 Following a joint trial with his Co-Defendant Olalekan Rufai, a jury convicted 

Defendant-Appellant Adedayo Adegboye of five counts of aiding and abetting health 

care fraud, in violation of 18 U.S.C. §§ 1347 and 2. On appeal, Adegboye argues that the 

trial evidence was insufficient to establish, beyond a reasonable doubt, that he knowingly 

and willfully participated in the fraud. Having jurisdiction under 28 U.S.C. § 1291, the 

panel majority affirms Adegboye’s convictions. Judge Matheson writes separately to 

dissent. 

I. BACKGROUND 

 We incorporate the facts, procedural history, and legal background from our 

opinion in the related appeal of United States v. Rufai, No. 12-6034, see §§ I, II.B. 

II. THERE WAS SUFFICIENT EVIDENCE TO SUPPORT ADEGBOYE’S 

CONVICTIONS 

 Adegboye argues that the Government failed to present sufficient evidence to 

prove beyond a reasonable doubt that he committed health care fraud as a principal or as 

an aider and abettor. Because the Government does not contend that he is guilty as a 

principal, however, we focus here only on whether there was sufficient evidence to 

convict him for aiding and abetting health care fraud. 

Adegboye acknowledges that his business associate Joshua Ohaka committed 

health care fraud by submitting false claims to Medicare through Adegboye’s company, 

First Century Medical Supply (“First Century”). And Adegboye does not dispute that his 

acts in fact contributed to Ohaka’s health care fraud generally, which would encompass 
3 

the incidents underlying the five substantive fraud counts charged against Adegboye. On 

appeal, Adegboye argues that the Government failed to present sufficient evidence from 

which a reasonable jury could have found, beyond a reasonable doubt, that he knowingly 

and willfully aided Ohaka’s fraudulent scheme. 

A. Relevant legal principles 

Our decision to affirm Adegboye’s convictions is grounded on two legal 

principles. First, we review the sufficiency of the evidence to support Adegboye’s 

convictions de novo, asking “whether a reasonable jury could find [him] guilty beyond a 

reasonable doubt.” United States v. Anaya, --- F.3d ---, 2013 WL 4308093, at *4 (10th 

Cir. Aug. 16, 2013) (internal quotation marks omitted) (alterations omitted). In making 

this determination, we must “consider all evidence and reasonable inferences in the light 

most favorable to the government, and we may not weigh evidence or consider credibility 

of witnesses.” United States v. Renteria, 720 F.3d 1245, 1253 (10th Cir. 2013). “Rather 

than examining the evidence in bits and pieces, we evaluate the sufficiency of the 

evidence by considering the collective inferences to be drawn from the evidence as a 

whole.” United States v. Bader, 678 F.3d 858, 873 (10th Cir. 2012) (internal quotation 

marks omitted) (alteration omitted), cert. denied, 133 S. Ct. 355 (2012). “[T]he evidence, 

together with the reasonable inferences to be drawn therefrom, must be substantial, but it 

need not conclusively exclude every other reasonable hypothesis and it need not negate 

all possibilities except guilt.” United States v. MacKay, 715 F.3d 807, 812 (10th Cir. 
4 

2013) (internal quotation marks omitted), petition for cert. filed, (U.S. Aug. 26, 2013) 

(No. 13-274). 

Second, to obtain a conviction for aiding and abetting, the Government had to 

prove beyond a reasonable doubt that Adegboye “(1) willfully associated himself with 

[Ohaka’s] criminal venture and (2) sought to make the venture succeed through some 

action of his own.” United States v. Rosalez, 711 F.3d 1194, 1205 (10th Cir. 2013) 

(internal quotation marks omitted) (alteration omitted), petitions for cert. filed, (U.S. June 

25, Aug. 9 and 26, 2013) (Nos. 13-5160, 13-5782, 13-6149). “[C]onduct of the 

defendant or special circumstances may justify the inference that the defendant associated 

himself with the criminal objective.” United States v. Burks, 678 F.3d 1190, 1198 (10th 

Cir. 2012) (internal quotation marks omitted) (alteration omitted). 

B. There was sufficient evidence to support Adegboye’s convictions for aiding and 

abetting Ohaka’s health care fraud 

1. Joshua Ohaka’s underlying fraud

Because the Government charged Adegboye with aiding and abetting his business 

associate Joshua Ohaka’s health care fraud, we begin by addressing briefly Ohaka’s 

fraudulent scheme. Ohaka’s modus operandi was to create a durable medical equipment 

company; qualify that company as a Medicare provider; submit false claims to Medicare 

through that company until Medicare became suspicious and began requiring the 

company to submit proof of its claims; unable to present proof, Ohaka would then create 
5 

a new company through which to continue his fraud.1 Ohaka began this scheme by using 

his own company, Optimed, through which he filed fraudulent Medicare claims from 

2005 through approximately October 2006. He continued the scheme with Vitacare, a 

company Ohaka formed in his wife’s name in 2007, and then he used his second 

company, Providence, beginning in 2008. Later, Ohaka paid Helen Etinfoh to let him use 

her name to operate another company, Luant and Odera, in 2008. This was likely due to 

the fact that, by this time, Medicare had flagged for investigation any company that was 

related to Ohaka. And Ohaka continued his fraud through First Century, a company that 

he formed with Defendants Adegboye and Rufai in the fall of 2007. 

The false claims Ohaka filed through these companies included billing Medicare 

for equipment that he never provided Medicare beneficiaries, billing Medicare for more 

expensive equipment than the equipment he actually provided beneficiaries (i.e., 

providing power scooters, but billing Medicare for more expensive power wheelchairs), 

and providing beneficiaries with medical equipment that was medically unnecessary and 

not prescribed for the beneficiaries by their doctors, as Medicare required. Often 

Ohaka’s companies would bill Medicare using the code CR (catastrophe-related), which 

indicated that a Medicare beneficiary had lost previously prescribed medical equipment 

during a catastrophe, such as a hurricane. By using this code, Medicare would reimburse 

 

1

 Although we refer in this opinion only to Medicare, Medicare frequently acted through 

various contractors. Those contractors, for instance, acted on Medicare’s behalf to 

review applications to be a Medicare provider, conduct site visits of applicants, process 

and pay provider claims for reimbursement, and investigate possible fraud. 
6 

Ohaka’s company for replacing the lost medical equipment without first requiring proof 

that a doctor had prescribed the equipment for the Medicare beneficiary. 

Ohaka opened four of the five companies he used to carry out his fraud (Optimed, 

Vitacare, Providence and First Century) in Oklahoma, stocked them with minimal to no 

inventory, and hired a very few employees to man the stores and company offices. The 

same employees often worked for several of Ohaka’s companies. The only real business 

these companies had was to file claims with Medicare seeking reimbursement. Ohaka 

carried out his fraud by, first, using “recruiters” to obtain information from Medicare 

beneficiaries, who usually lived in Texas or Louisiana. Then Ohaka, who lived in Texas, 

would send this information to his employees in Oklahoma, direct them to use that 

information to prepare the Medicare claim forms, his employees would do so and then, 

pursuant to Ohaka’s instructions, send the completed claim forms either back to Ohaka or 

to a billing company he used to bill Medicare.2

 

 

2

 Evidence indicated that Ohaka would send “recruiters” out to take orders from real 

Medicare beneficiaries. Even though those beneficiaries had never been prescribed 

motorized scooters or wheelchairs, the “recruiters” apparently asked the beneficiaries if 

they wanted a scooter or wheelchair, promised to deliver one, and then obtained from the 

beneficiaries the information needed to file a claim for reimbursement from Medicare. 

Sometimes Ohaka would not provide the beneficiaries with any equipment, but still bill 

Medicare. Sometimes Ohaka would provide the beneficiary with a power scooter, but 

bill Medicare for a more expensive power wheelchair. (As explained in footnote 3, infra., 

the five substantive counts of Medicare fraud charged against Adegboye appear to be this 

type of fraud.) And sometimes the beneficiaries would not ask for any equipment, but 

Ohaka would send them a power scooter anyway and then bill Medicare. 

 
7 

2. Evidence that Adegboye aided and abetted Ohaka’s fraud 

The specific question presented in this appeal is whether there was sufficient 

evidence from which a jury could find, beyond a reasonable doubt, that Adegboye 

knowingly and willfully aided and abetted Ohaka’s fraud.3

 “To establish knowledge and 

willfulness, ‘the Government must prove that the defendant acted with knowledge that 

his conduct was unlawful.’” United States v. Franklin-El, 555 F.3d 1115, 1122 (10th Cir. 

 

3

 The United States charged Adegboye with six counts. The jury acquitted Adegboye of 

Count 1, charging him with conspiring to commit health care fraud. The jury also 

convicted Adegboye on Counts 2 through 6, charging him with aiding and abetting five 

substantive counts of health care fraud. Briefly summarized, the evidence regarding each 

of those counts was as follows: Count 2 – On August 20 or 21, 2008, First Century 

provided Medicare beneficiary Mary Smallwood with a power scooter, but charged 

Medicare instead for a more expensive power wheelchair, for which Medicare 

reimbursed First Century $3,516. Smallwood’s doctor had not prescribed either power 

mobility device for Smallwood, as required for Medicare reimbursement. Count 3 – First 

Century billed Medicare for providing Medicare beneficiary Rosa Mason, on July 15, 

2008, a power wheelchair, which her physician had not prescribed, and for which 

Medicare reimbursed First Century $3,516. Count 4 – On July 15, 2008, First Century 

provided Medicare beneficiary Gladys Tatum with a power scooter, but billed Medicare 

instead for a more expensive power wheelchair, for which Medicare reimbursed First 

Century $3,516. Tatum’s doctor did not prescribe either power mobility device for her. 

Count 5 – On August 4, 2008, First Century provided Medicare beneficiary Ms. Glendale 

Sanders a power scooter, but billed Medicare instead for a more expensive power 

wheelchair, for which Medicare reimbursed First Century $3,516. Sanders’ doctor did 

not prescribe either device for her. Count 6 – On May 28, 2008, First Century provided 

Medicare beneficiary Martha Eddington a power scooter, but billed Medicare for a more 

expensive power wheelchair, for which Medicare reimbursed First Century $3,516. 

Eddington’s doctor had not prescribed either device for her. Each of these beneficiaries 

lived in Texas or Louisiana. And in each of these cases, First Century, in billing 

Medicare, used the code CR, which was to be used when a Medicare beneficiary lost her 

medical mobility equipment due to a catastrophe such as Hurricanes Katrina, Rita, and 

Gustav. None of these Medicare beneficiaries, however, had been impacted by such a 

catastrophe. Medicare would allow a claim of $4,000-5,000 for a power wheelchair, for 

which Medicare would pay approximately $3,516. On the other hand, Medicare would 

allow a claim of approximately $2,000 for a power scooter. 
8 

2009) (quoting Bryan v. United States, 524 U.S. 184, 191-92 (1998) (internal quotation 

marks omitted) (emphasis omitted).) We conclude there was sufficient evidence to 

support Adegboye’s convictions. More specifically, there was sufficient evidence from 

which a reasonable jury could have found the following: 1) Adegboye knew that he and 

Defendant Rufai were straw owners of First Century, that First Century’s only business 

was with Medicare and its beneficiaries, and that it was actually Ohaka who was 

operating the company; 2) Adegboye knew that he and Rufai were straw owners because 

Ohaka wanted to hide his involvement in First Century from Medicare; 3) Adegboye 

knew that Medicare was reimbursing First Century hundreds of thousands of dollars for 

providing medical equipment to Medicare beneficiaries, and yet First Century had no 

inventory and no apparent means to purchase inventory; 4) Adegboye knew Medicare 

beneficiaries were complaining that they were not receiving equipment they had ordered 

from First Century; 5) when Medicare began investigating First Century and throughout 

Medicare’s investigation, Adegboye actively tried to cover up the fraud Ohaka was 

committing through First Century; and 6) Adegboye profited from First Century’s fraud. 

Considered together, this evidence was sufficient to support the jury’s ultimate finding, 

beyond a reasonable doubt, that Adegboye knowingly and willfully aided and abetted 

Ohaka’s fraud. 
9 

a. Evidence that Adegboye knew that he and Rufai were straw owners 

of Ohaka’s company, First Century, whose only business was with 

Medicare and its beneficiaries 

 

We begin by considering what Adegboye knew about First Century. There was 

evidence from which the jury could have found, beyond a reasonable doubt, that 

Adegboye knew that he and Rufai were straw owners of First Century and that it was 

Ohaka who actually ran the company. At Ohaka’s direction, Rufai incorporated First 

Century in September 2007, naming Adegboye as First Century’s president and Rufai as 

its vice president. There is no indication that, in doing so, Adegboye or Rufai contributed 

any capital. 

A month later, Adegboye, who lived in New York, visited Oklahoma City with 

Rufai. At that time, directed by Ohaka, Adegboye and Rufai opened bank accounts for 

First Century. There is no indication in the record as to who made any financial 

contribution to First Century, and in what amount, when these bank accounts were 

opened. Also at this time, Adegboye and Rufai, still directed by Ohaka, also obtained 

general liability insurance for First Century and began making arrangements to lease 

commercial space. Adegboye was also present when Ohaka hired an employee, Tracina 

Pratcher, to work for both Ohaka’s company Vitacare and for First Century. 

There was also evidence from which a jury could have found that Adegboye knew 

that First Century’s business model was to provide only durable medical equipment that 

would be reimbursable by Medicare. Although by January 2008, First Century opened in 

a shopping center storefront, manned by one employee, Pratcher, First Century had no 
10 

inventory and never attempted to provide equipment in any context other than to 

Medicare beneficiaries. Thus, although ostensibly open in January 2008, First Century 

did no business until after Medicare approved it as a Medicare provider on May 20, 2008. 

There was further evidence from which the jury could have found that Adegboye 

knew, not only that Ohaka was actually the one operating First Century, but that Ohaka 

was doing so in conjunction with his other companies. In addition to the evidence that 

Ohaka hired Pratcher to work at both Ohaka’s company Vitacare and at First Century, 

Adegboye was present when Ohaka directed his employees to train Pratcher on how to 

complete the Medicare reimbursement forms. And Ohaka had his Vitacare office 

manager contact Adegboye several times regarding administrative details that needed to 

be addressed on First Century’s behalf. 

Further, Adegboye and Rufai were the only signatories on First Century’s bank 

accounts, and it was only Adegboye who wrote checks on the accounts. This put 

Adegboye in a position to know that First Century was incurring expenses—rent, wages, 

office equipment, remodeling work—but was not paying those expenses, at least not out 

of First Century’s bank account. In fact, Bank of America eventually closed First 

Century’s initial bank account due to inactivity. Not until several months after Medicare 

began reimbursing First Century, in August 2008, did Adegboye pay First Century’s rent, 

payroll and other overhead expenses from First Century’s new bank accounts. And once 

Adegboye began paying those expenses for First Century, he also wrote checks for rent, 

insurance and payroll for several of Ohaka’s other companies. Thus, Adegboye knew 
11 

that he and Ohaka were operating First Century in conjunction with Ohaka’s other 

companies. 

From all of this evidence, then, a jury could have found that Adegboye knew, from 

the outset of First Century’s incorporation, that he and Rufai were straw owners of First 

Century, which did business only with Medicare beneficiaries, and that Adegboye knew 

that it was actually Joshua Ohaka who was running First Century, and running it in 

conjunction with his other companies.4

 

b. Evidence that Adegboye knew that Ohaka wanted to hide from 

Medicare the fact that Ohaka was actually operating First Century 

There was also evidence from which a reasonable juror could have found, beyond 

a reasonable doubt, that Adegboye knew that this business arrangement he had with 

Ohaka, Rufai and First Century, in which he acted as one of the straw owners of First 

Century, was the result of Ohaka’s desire to keep from Medicare the fact that he was 

actually operating First Century. It was Adegboye who completed the application for 

First Century to become a Medicare durable medical equipment provider. In making this 

application, Adegboye misrepresented to Medicare that he alone owned and operated 

First Century. See Franklin-El, 555 F.3d at 1121, 1123 (relying in part on the 

defendant’s misrepresentations to uphold his conviction for health care fraud). 

 

4

 Neither the defense nor the dissent disputes that a jury could have found that Adegboye 

knew 1) that he and Rufai were straw owners and 2) that it was Ohaka who was actually 

running First Century. 
12 

More specifically, the Medicare application required Adegboye to list “[a]ll 

persons who have a 5 percent or greater ownership (direct or indirect) interest” in First 

Century; “all officers and directors” of First Century; “[a]ll managing employees,” 

defined as “a general manager, business manager, administrator, director, or other 

individual who exercises operational or managerial control over, or who directly or 

indirectly conducts, the day-to-day operations” at First Century, whether or not that 

person is a First Century employee; and “[a]ll individuals with a partnership interest” in 

First Century. (Gov’t Ex. 1F, Section 6.) In response, Adegboye falsely listed only 

himself, as an owner of 5% or more of First Century and as First Century’s managing 

employee. Adegboye did not list Joshua Ohaka (or even Rufai for that matter) in any 

capacity. This same section of the Medicare application further inquired whether any 

listed person had been suspended from any federal health care program such as Medicare. 

A jury could have found, then, that Adegboye misrepresented to Medicare that he, 

and not Ohaka, owned and operated First Century. Adegboye made this 

misrepresentation despite the one and one-half pages of notice to Medicare billing 

applicants that making false representations in the application is a crime. 

The Medicare application further mandated that the applicant update any of the 

required information. Later, during and after the Medicare approval process, when 

Medicare twice directed Adegboye to revise First Century’s documentation to list First 

Century’s office manager as a managing employee, Adegboye still never mentioned 

Ohaka. 
13 

Further, when Medicare first began investigating First Century, in October 2008, it 

asked for a number of documents and other information that would bring First Century 

into compliance with Medicare’s requirements. Adegboye, who assisted in providing 

First Century’s response to Medicare’s request, still did not indicate that Ohaka was 

involved in operating First Century. Even months after First Century ceased operating, 

Adegboye and his attorneys, in explaining to investigating officials why Ohaka, and not 

Adegboye, had possession of First Century’s records, indicated only that Ohaka was 

Adegboye’s friend and still never mentioned that Ohaka played any role in operating 

First Century. A jury could infer from this conduct that Adegboye, from the outset of 

First Century’s incorporation, knowingly helped Ohaka hide from Medicare the fact that 

Ohaka was the one actually operating First Century. 

On appeal, Adegboye points out that the documents he submitted to Medicare 

showed that First Century was connected with Ohaka. More specifically, as part of the 

application to become a Medicare provider, Adegboye provided Medicare with copies of 

contracts between First Century and Ohaka’s company Vitacare in which Vitacare agreed 

to sell First Century medical equipment and to service equipment for First Century’s 

customers. Ohaka signed one of those contracts. Nonetheless, this fact was not enough 

to flag, for Medicare, Ohaka’s involvement in operating First Century. Nor does it 

absolve the misrepresentations Adegboye made in applying, on First Century’s behalf, to 

become a Medicare provider. 
14 

From the evidence presented at trial, then, a jury could have found, beyond a 

reasonable doubt, that Adegboye knew that Ohaka did not want Medicare to know First 

Century was Ohaka’s company and Adegboye took action to hide that fact from 

Medicare. From this evidence alone, a jury might be able to infer that Adegboye thus 

knew that Ohaka was committing Medicare fraud through First Century. But there was, 

in any event, still more evidence from which a jury could infer that Adegboye knew the 

specifics of Ohaka’s health care fraud. 

c. Evidence that Adegboye knew that Medicare was reimbursing First 

Century for medical equipment it purportedly provided to Medicare 

beneficiaries, yet First Century had no inventory of durable medical 

equipment, nor any apparent means to purchase such inventory 

Although Adegboye was the straw owner of First Century, he was not completely 

an absentee owner. Instead, he remained involved with the company’s operation 

throughout its existence.5

 Two aspects of Adegboye’s continued involvement with First 

Century, in particular, put Adegboye in a position to know about the company’s 

fraudulent Medicare billing. First, after applying on First Century’s behalf for a 

Medicare billing number, Adegboye remained one of First Century contacts with 

Medicare. And second, Adegboye (with Rufai) was the only one with control over First 

 

5

 This fact provides a contrast between Adegboye, whose convictions we uphold here, 

and his co-defendant Rufai, whose convictions we reverse in an accompanying opinion. 

There was no evidence presented to the jury that Rufai’s involvement in First Century 

continued after January or perhaps March 2008, several months before Medicare 

approved First Century to be a Medicare provider and, thus, several months before First 

Century began filing false claims for reimbursement with Medicare. Adegboye, on the 

other hand, remained involved with First Century throughout its existence. 
15 

Century’s bank accounts. Cf. United States v. Dazey, 403 F.3d 1147, 1156, 1160 (10th 

Cir. 2005) (upholding fraud conviction in part because defendant controlled bank 

accounts of fraudulent investment company). 

As the person controlling First Century’s bank accounts, a jury could have found, 

beyond a reasonable doubt, that Adegboye knew the following: First Century never had 

an inventory of durable medical equipment. Nor did First Century have funds to 

purchase equipment. 

When Rufai incorporated First Century, neither Adegboye nor Rufai contributed 

any capital. Nor was there any evidence that First Century obtained financing or other 

funding to purchase inventory from any other source. First Century’s initial bank 

account, opened in October 2007, was eventually closed for lack of activity. And, 

although First Century incurred expenses during its start-up period—rent, wages, 

insurance, office equipment, remodeling its rented commercial space—First Century 

itself did not pay those expenses. Thus, in its start-up phase, First Century did not have 

funding to purchase inventory.

When Adegboye initially applied for First Century to be a Medicare provider, in 

January 2008, Adegboye did submit agreements he had signed with two of Ohaka’s other 

companies, Optimed and Vitacare, extending credit to First Century to facilitate its 
16 

purchasing inventory from those two Ohaka companies.6 But there is no indication that 

First Century ever purchased inventory from these two Ohaka companies. 

During its pre-approval inspection of First Century, in March 2008, Medicare’s 

inspector noted that First Century had little inventory on hand, only a manual wheelchair 

and a walker contributed by First Century employee Tracina Pratcher. Due to the lack of 

inventory, Medicare, before approving First Century to be a Medicare provider, requested 

additional information from First Century in order to establish that it would be able to 

purchase durable medical equipment to supply Medicare beneficiaries. This is because 

Medicare has found that one of the telltale signs of fraudulent billing is a company’s lack 

of inventory. In response to Medicare’s inquiry, Adegboye, in April 2008, provided 

Medicare with a letter of credit from a non-Ohaka company, Summit Durable Medical 

Equipment Co. There is no indication, however, that First Century purchased equipment 

from Summit until late September 2008. 

Medicare approved First Century to be a Medicare provider on May 20, 2008. 

First Century immediately began submitting claims to Medicare for reimbursement, even 

before it reopened its bank accounts on May 30, 2008. Yet there is no indication that 

 

6

 Medicare did not consider at least the letter of credit from Optimed to be valid, for 

purposes of First Century’s application to be a Medicare provider, because Adegboye 

failed to provide Medicare with a copy of this agreement that included both parties’ 

signatures. 
17 

First Century had any inventory, or had yet purchased medical equipment, at this point in 

time.7

 

Through the next four months, from May 20 to September 30, 2008, First Century 

billed Medicare $1.2 million for equipment provided to 150 Medicare beneficiaries. And 

beginning August 1, 2008, Medicare deposited over $300,000 into First Century’s bank 

accounts. And yet there was no indication that First Century had ever purchased or paid 

for any durable medical equipment up until September 19, 2008. Adegboye’s continued 

involvement with First Century and his control over First Century’s bank accounts placed 

him in a position to know this. 

Moreover, Adegboye physically visited First Century’s Oklahoma City storefront 

sometime in September 2008. It was during this same time period that Medicare, on 

September 22, 2008, conducted the unannounced inspection of First Century that 

eventually led to that company’s downfall. During that inspection, Medicare noted that 

First Century had almost no inventory at its office location (one manual wheelchair), the 

employee manning the store did not know the name of the owner and, although 

Adegboye, in the application he filed on First Century’s behalf, indicated that First 

 

7

 The record contains a receipt issued by one of Ohaka’s companies, Luant and Odera, to 

First Century, dated May 7, 2008. That receipt indicates that First Century purchased 

thirty-nine power wheelchairs for a sum of $39,000, for which First Century paid cash. 

First Century, with Adegboye’s participation, submitted this receipt to Medicare in 

November 2008, after Medicare began investigating, among other things, First Century’s 

lack of inventory. A jury would not have had to credit this evidence, however, in light of 

contradictory evidence from First Century employees, particularly Florida Raines, that 

First Century had no inventory during this time period. See Dazey, 403 F.3d at 1160. 

Adegboye does not specifically rely upon this receipt, either at trial or on appeal. 
18 

Century would keep its customer files at the First Century storefront, there were only 

about ten files there, and those were incomplete and filled primarily with empty forms. 

From that evidence, a jury could further infer that Adegboye, because he had physically 

visited First Century at approximately the same time as Medicare’s inspection, was aware 

that First Century, in September 2008, had no inventory and minimal to no customer 

files. 

From this evidence, then, a reasonable jury could have found, beyond a reasonable 

doubt, that Adegboye knew that Ohaka was committing health care fraud through First 

Century, knew the essential nature of that fraud, and knowingly and willfully aided that 

fraud. There is, however, still more evidence to support Adegboye’s convictions. 

d. Evidence that Adegboye knew First Century customers were 

complaining about not getting equipment they ordered and receiving 

equipment that they had not ordered 

There was also some evidence that Adegboye was generally aware that First 

Century customers had been calling to complain about not receiving equipment they 

needed, and receiving equipment that they did not request. This evidence, considered 

with the other evidence previously mentioned, would further support the jury’s finding 

that Adegboye knew of Ohaka’s fraud and knowingly and willfully aided it. 

 e. Adegboye’s efforts to cover up First Century’s fraud 

Perhaps the most compelling evidence that Adegboye knowingly and willfully 

aided Ohaka’s fraud was evidence that Adegboye actively tried to cover up Ohaka’s 

fraud, once Medicare began investigating First Century, in the fall of 2008. See United 
19 

States v. Verners, 53 F.3d 291, 295 (10th Cir. 1995) (upholding conviction for aiding and 

abetting drug trafficking where, among other things, defendant actively attempted to 

conceal drugs). After Medicare’s unannounced site visit to First Century, in September 

2008, Medicare, on October 15, 2008, notified First Century that it had failed to comply, 

in a number of ways, with Medicare’s standards applicable to durable medical equipment 

companies. One of the deficiencies Medicare noted was that “[t]he inventory displayed 

during your site inspection is not sufficient based on the amount you bill Medicare.” 

(Gov’t Ex. 1N at 2.) (Recall that First Century, between May 20 and September 30, 

2008, billed Medicare for over $1.2 million for medical equipment provided for Medicare 

beneficiaries, yet there is no evidence that First Century purchased or otherwise acquired 

any inventory during this same general time period.) “In order to prove compliance with 

this [Medicare] standard,” Medicare directed First Century “to submit all invoices for the 

month of June 2008, along with all credit agreements and contracts for inventory. These 

credit agreements and contracts must contain all the information required by [Medicare] 

to be considered valid.” (Id.) Medicare gave First Century twenty-one days to correct 

this and a number of other deficiencies in its compliance with Medicare standards. 

Adegboye participated in preparing First Century’s response to this notice and its 

attempt to correct the cited deficiencies. In response to Medicare’s direction to submit 

First Century’s June 2008 invoices, First Century submitted, among other documents, an 

invoice from another of Ohaka’s companies, Luant and Odera, indicating that on May 7, 

2008, Luant and Odera sold First Century $39,000 in power wheelchairs, for which First 
20 

Century paid cash;8 a list indicating that First Century had purchased over $74,000 in 

medical equipment from Summit between June 1 and November 7, 2008; and invoices 

from Summit to First Century dated between September 19 and November 6, 2008. 

In addition, within one week of Medicare’s October 15, 2008 notice to First 

Century, Adegboye wrote a check on one of First Century accounts for $115,000, payable 

to one of Joshua Ohaka’s other companies, Providence, purportedly for the purchase of 

equipment. Adegboye himself then endorsed the check for Providence and deposited the 

check in Providence’s account. While First Century did have contractual relationships 

and letters of credit with other companies owned and operated by Joshua Ohaka, there is 

no evidence that First Century had any such relationship with Ohaka’s Providence. Nor 

is there any indication that First Century actually obtained any medical equipment from 

Providence. A jury could reasonably have found, beyond a reasonable doubt, that 

Adegboye’s thus transferring over $115,000 in funds from First Century to Providence, 

and his participation in submitting to Medicare the wrong invoices, were efforts 

Adegboye undertook to cover up the health care fraud that Ohaka was committing 

through First Century. The jury could, thus, have found beyond a reasonable doubt that 

Adegboye knew of Ohaka’s fraud and aided it. 

 

8

 As previously mentioned, the jury would not have been required to credit the veracity of 

this receipt, in light of contrary testimony from Florida Raines, who was working at First 

Century at this time, that First Century did not purchase any medical equipment and did 

not have any inventory during this same time period. See Dazey, 403 F.3d at 1160. 
21 

But there is still more. In October 2008, Medicare placed First Century on 

prepayment status, meaning Medicare would not reimburse any more claims from First 

Century until First Century submitted to Medicare documentation to prove each claim 

submitted. When First Century could not comply with Medicare’s requests for 

documentation of its claims, and when First Century failed to correct its noncompliance 

with Medicare’s standards for durable medical equipment suppliers, Medicare, in January 

2009, revoked First Century’s Medicare provider number. At that time, Medicare again 

requested First Century’s records. No one, including Adegboye, responded to that 

request for months. 

In July 2009, the United States indicted Joshua Ohaka for health care fraud 

committed through another of his companies, Luant and Odera. In August 2009, 

Adegboye’s attorney sent a letter notifying the Federal Bureau of Investigation (“FBI”) 

that when FBI agents in Houston seized documents from Ohaka, they also seized First 

Century’s records. Adegboye’s attorney explained to the FBI that the reason Ohaka had 

First Century’s records was because Adegboye had given those records to Ohaka for 

“safekeeping,” when Adegboye was in the process of moving First Century to New York. 

Adegboye’s attorney asked the FBI to sort through the records it had seized from Ohaka 

and remove First Century’s records and return those to Adegboye, so he could respond to 

Medicare’s request for his First Century records. Adegboye still did not reveal Ohaka’s 

role in operating First Century. 
22 

Medicare apparently asked Adegboye again for First Century’s records on 

September 16, 2009. In response, Adegboye sent a sworn affidavit to Medicare, 

indicating the following: He owned First Century; because of financial difficulties, 

Adegboye decided to move First Century from Oklahoma City to New York; for this 

reason, Adegboye requested that his long-time friend Ohaka box First Century’s files and 

ship them to Adegboye in New York; because Ohaka lives in Texas, he first took First 

Century’s records to his home in Houston; when the FBI seized Ohaka’s files, agents 

seized First Century’s files, too; although Adegboye’s attorney had requested that the FBI 

locate First Century’s files and return those to Adegboye, Adegboye had not yet heard 

back from the FBI. For these reasons, Adegboye asked Medicare for additional time to 

respond to its request for First Century’s records. Adegboye, then, continued to 

misrepresent that he was First Century’s owner and Ohaka was not involved in running 

the company.9

 

 

9

 This case is distinguishable from United States v. Rahseparian, 231 F.3d 1257 (10th Cir. 

2000), on which the dissent relies. In Rahseparian, this Court reversed Jack 

Rahseparian’s convictions for mail fraud and conspiracy to commit mail fraud, which 

were based solely on false exculpatory statements that Rahseparian made to police one 

and one-half years after the conclusion of a fraudulent scheme operated by others through 

a business with which Rahseparian was tangentially involved. Id. at 1261-64. This Court 

concluded that Rahseparian’s after-the-fact exculpatory statements did not support the 

inference that he knew of the fraud at the time it was occurring. Id. at 1264. In this case, 

assuming Adegboye’s September 2009 after-the-fraud affidavit was an exculpatory 

statement—if Adegboye had not known of Ohaka’s fraud, a more exculpatory statement 

might have been that it was really Ohaka who was running First Century—there was, 

unlike in Rahseparian, additional evidence indicating Adegboye had been aware, the 

entire time, of Ohaka’s scheme to defraud Medicare through First Century, and that 

Adegboye acted to facilitate that scheme throughout First Century’s existence. Thus, a 
23 

Even more telling, however, was that, just a month before Adegboye and his 

attorney indicated to investigators that Ohaka was not involved in running First Century, 

Adegboye was taking a markedly different tone with Ohaka. On July 6, 2009, Adegboye 

sent Ohaka an email stating the following: 

I know you have refused to pick my calls. No PROBLEM. But the issue of 

First Century is a recurring decimal, not untill [sic] we sit down and tackle 

the issue like matured and responsible adults, we are only postponing the 

evil day. And i [sic] pray it does not get to that stage. 

Please go through the attached doc. [a collection notice indicating that 

Adegboye, as First Century’s rent guarantor, owed over $43,000 for First 

Century’s unpaid rent] and advise. They claim no key was giving [sic] to 

them., [sic] which you confirmed to be true. 

I will be expecting your call. 

(Ex. 31.) 

From this evidence, viewed together with the other evidence previously 

mentioned, a jury could find, beyond a reasonable doubt, that Adegboye knowingly and 

willfully aided Ohaka’s fraud, including actively trying to cover it up. 

 f. Adegboye profited from First Century’s fraud 

Lastly, there was evidence that Adegboye profited some from First Century’s 

fraud. This evidence further supports the jury’s finding, beyond a reasonable doubt, that 

Adegboye knew about Ohaka’s fraud and willfully aided it. See Verners, 53 F.3d at 295 

(upholding conviction for aiding and abetting drug trafficking where, among other things, 

 

reasonable jury could have found that Adegboye’s September 2009 affidavit was a 

continuation of his efforts undertaken throughout the fraudulent scheme to help Ohaka 

conceal from Medicare his involvement in First Century. 
24 

evidence indicated that defendant benefitted from drug trafficking occurring in her 

home). 

g. Viewing this evidence as a whole, a reasonable jury could have 

found Adegboye guilty, beyond a reasonable doubt, of knowingly and 

willfully aiding and abetting Ohaka’s health care fraud 

Viewed in isolation, there could be innocent explanations for at least some of these 

circumstances, explanations which could have led a reasonable jury to find that Ohaka 

had duped Adegboye into unknowingly being the straw owner of a company through 

which Ohaka was defrauding Medicare. But viewing the evidence as a whole, a 

reasonable jury could also have found that Adegboye knew all along that Ohaka was 

defrauding Medicare through First Century, that Adegboye knowingly and willfully 

associated himself with that venture, and that Adegboye took action to help the venture 

succeed. That is sufficient evidence for a reasonable jury to find beyond a reasonable 

doubt that Adegboye aided and abetted the five substantive fraud counts charged against 

him.10 See United States v. Phillips, 543 F.3d 1197, 1210 (10th Cir. 2008) (affirming 

aiding-and-abetting convictions where, “[e]ven if none of the[] facts, taken alone, would 

be sufficient proof to uphold [the defendant’s] convictions, the combination” of facts 

supported by the evidence was sufficient to uphold the convictions). 

 

10 We do not read Adegboye’s brief to make a separate argument that his convictions 

were the result of jury confusion and mistake. But, to the extent he is making such an 

argument, we reject that contention as well. In response to the jury’s notes sent to the 

trial court during the jury’s deliberations, the court gave jurors additional instructions that 

cleared up any confusion. 
25 

III. CONCLUSION 

The question of whether there was sufficient evidence to support the jury’s 

finding, beyond a reasonable doubt, that Adegboye aided and abetted Ohaka’s fraud is a 

close one. But the jury found that Adegboye knew about Ohaka’s fraudulent scheme, 

willfully associated himself with that scheme, and acted to aid that scheme’s success. 

Because the Government presented sufficient evidence from which a reasonable jury 

could have reached that finding, beyond a reasonable doubt, we AFFIRM Adegboye’s 

convictions. 

 
12-6035, United States v. Adegboye

Judge MATHESON, dissenting1

 The majority correctly concludes the sufficiency of the evidence issue “is a close 

one.” Maj. Op. at 24. The Government presented substantial evidence that Medicare 

fraud occurred at First Century. In the related appeal of United States v. Rufai, No. 12-

6034, we concluded that the Government proved Mr. Ohaka knowingly committed 

Medicare fraud and Mr. Rufai and Mr. Adegboye performed functions at First Century 

that enabled Mr. Ohaka to do so. But proving what happened is not the same as proving 

knowledge. In Rufai, we held the evidence was insufficient to prove that Mr. Rufai 

knowingly aided and abetted health care fraud. Although Mr. Adegboye’s case is a closer 

one, I would hold the same here. The Government’s strong case against unindicted 

Medicare defrauder Mr. Ohaka should not be improperly imputed to others. 

 The critical issue is whether Mr. Adegboye knew about the fraudulent Medicare 

billing scheme at First Century and intended to defraud Medicare. At trial, the 

Government presented no direct evidence of Mr. Adegboye’s knowledge and intent, so 

the issue is whether the jury could reasonably have inferred knowledge and intent beyond 

a reasonable doubt based upon the circumstantial evidence. See United States v. 

Rahseparian, 231 F.3d 1257, 1262 (10th Cir. 2000). 

 

1 This dissenting opinion incorporates by reference the discussion of facts, procedural 

history, and legal background from Sections I.A., I.B., II.A. (except II.A.3.), II.B., and 

II.C.1. from this court’s unanimous opinion in the related appeal of United States v. 

Rufai, No. 12-6034. 
2 

A. Circumstantial Evidence 

After careful review of the record, I believe the circumstantial evidence relevant to 

the central question of Mr. Adegboye’s knowledge and intent falls into the following 

categories: (1) Mr. Ohaka’s role in managing First Century and committing Medicare 

fraud; (2) Mr. Adegboye’s role in setting up and maintaining First Century as a straw 

owner scheme; (3) Mr. Adegboye’s role in securing Medicare billing approval; (4) Mr. 

Adegboye’s role in managing First Century; and (5) Mr. Adegboye’s affidavit to 

Medicare, submitted after Mr. Ohaka had been indicted for health care fraud in Texas, 

omitting Mr. Ohaka’s role in First Century.2

1. Mr. Ohaka’s role at First Century 

Mr. Ohaka recruited Mr. Rufai and Mr. Adegboye and directed them in setting up 

the company. Testimony of First Century and Vitacare employees established that Mr. 

Ohaka played the dominant role in First Century’s management, including from May 

2008 to September 2008 when First Century was submitting false bills to Medicare. 

Although Mr. Adegboye was present at some hiring interviews (for employees who 

initially worked at Mr. Ohaka’s other DME companies and later at First Century), Mr. 

Ohaka hired the employees and decided who would work at each of the DME companies, 

including First Century. He decided which company would pay the employees and what 

 

2

 The majority opinion points to other evidence that it describes as evidence of a “cover 

up.” For reasons I explain below, this evidence does not support conclusions about Mr. 

Adegboye’s knowledge. 
3 

work they would do. He also monitored whether bills had been paid and whether First 

Century had renewed its state permits. He received First Century’s email correspondence 

from the NSC and forwarded it to Mr. Adegboye. Mr. Ohaka procured the Medicare 

customers, directed the employees in filling out the Medicare paperwork, and decided 

whether First Century or one of his other companies would submit the claims. 

Mr. Ohaka’s DME company employees considered him to be the manager and/or owner 

of First Century. Ms. Pratcher, a Vitacare and First Century employee, testified that 

Messrs. Ohaka, Rufai, and Adegboye were partners in the medical supply business, 

including Vitacare and First Century, with Mr. Ohaka as the senior partner. She testified 

that she called Mr. Ohaka with questions or problems whenever she could not get in 

touch with Mr. Rufai or Mr. Adegboye. Ms. Rinker testified that she had assumed Mr. 

Ohaka was an owner of First Century, and because of this belief she told inspectors at the 

March 2008 site inspection that First Century’s owner had other DME companies. She 

further testified that Mr. Ohaka was her first point of contact for First Century business, 

that First Century and Mr. Ohaka’s other businesses were run the same way, and that 

“[t]hings were always jumbled in between the businesses.” Trial Tr. at 227. 

 Mr. Ohaka called the shots at First Century. Employees recognized him as the 

owner and lead manager. It is reasonable to conclude that Mr. Adegboye regarded Mr. 

Ohaka similarly, that he knew Mr. Ohaka controlled what happened at the company. 

Without more proof, however, it does not follow Mr. Adegboye knew everything that Mr. 

Ohaka did, including submission of false billing claims to Medicare. 
4 

2. Straw owner scheme 

Mr. Adegboye’s actions to set up and maintain First Century from September 2007 until 

January 2009 support a finding that he knew he was a straw owner. The Government 

presented substantial evidence that Mr. Adegboye and Mr. Rufai acted as straw owners at 

First Century while Mr. Ohaka managed the company behind the scenes. Mr. 

Adegboye’s name was listed on all First Century legal documents: articles of 

incorporation, bank accounts, service agreements, purchase agreements, leases, insurance 

contracts, and Medicare application materials. Mr. Ohaka’s name did not appear on any 

of these documents. 

 Although silent business partners are not uncommon in lawful enterprises, a jury 

could conclude that the straw owner scheme established for First Century raised a red 

flag to Mr. Adegboye that “something was amiss” at First Century. See United States v. 

Lovern, 590 F.3d 1095, 1106 (10th Cir. 2009). But knowing that something was amiss is 

not sufficient to conclude that Mr. Adegboye knew Mr. Ohaka was planning to or did 

submit false bills for Medicare reimbursement. See id. (reversing conviction for 

insufficient evidence). 

3. Medicare billing approval 

 From January 2008 to May 2008, Mr. Adegboye participated in securing Medicare 

billing approval for First Century. On January 8, he signed and submitted First Century’s 

enrollment application materials to bill Medicare. The application warned of criminal 

penalties for providing false information. It also warned that “payment of a claim by 
5 

Medicare is conditioned upon the claim and the underlying transaction complying with 

[Medicare] laws, regulations, and program instructions” and that the Medicare provider 

could not “submit claims with deliberate ignorance or reckless disregard of their truth or 

falsity.” Government Trial Ex. # 1F, Aplee. Suppl. Appx. at 61. In Section 6 of the 

application, Mr. Adegboye was required to list any individuals with a five percent or 

greater ownership, anyone with a partnership interest, and all managing employees. 

 In the initial application, Mr. Adegboye listed only himself as an owner and 

managing employee, which was consistent with the virtual absence of business activity at 

First Century during the period of pre-Medicare approval,3

 but inconsistent with Mr. 

Ohaka’s assistance in setting up First Century. Mr. Adegboye attached to the application 

a letter of credit signed by Mr. Ohaka. Despite a continuing duty to update the 

application, he never listed Mr. Ohaka as an owner or managing employee,4

 even though 

a jury could reasonably infer that Mr. Adegboye knew Mr. Ohaka was managing First 

Century as a Medicare reimbursement business. On the enrollment materials, Mr. 

 

3 Ms. Raines testified that when she worked at First Century, before it was approved to 

bill Medicare, First Century only sold some scrubs. Nothing in the record indicates any 

other non-Medicare sales at First Century. 

4

 He certified that he would notify the NSC of any changes to the information in the 

application within 30 days. This requirement was reinforced after the March and 

September 2008 site inspections, when the NSC discovered first Ms. Rinker and later Ms. 

Unsell at the store and informed Mr. Adegboye that he should list them as managing 

employees. He did so as to Ms. Rinker but listed Ms. Unsell as a “delegated official,” 

someone with “the authority to [make] changes and updates to the” Medicare application. 

A delegated official must be listed elsewhere in the application as an owner or managing 

employee. 
6 

Adegboye directed that all email correspondence from Medicare be sent to an email 

address belonging to Mr. Ohaka, one that did not identify Mr. Ohaka as the recipient. 

 I address below whether Mr. Adegboye’s handling of the Medicare application is 

“enough to transform the government’s weak evidence . . . into proof [of knowledge] 

beyond a reasonable doubt.” United States v. Leos-Quijada, 107 F.3d 786, 795 (10th Cir. 

1997) (reversing for insufficient evidence).

4. Mr. Adegboye’s role at First Century 

 Mr. Adegboye functioned as a straw owner and was mostly in New York and 

absent from the First Century office in Oklahoma. He visited occasionally and stayed in 

touch by telephone and email, but the record lacks evidence that he visited during the 

time that First Century submitted the false bills to Medicare underlying the charges in the 

indictment. He helped run the business by paying bills,5

 responding to issues raised by 

employees, and communicating with Mr. Ohaka. He also withdrew funds from the First 

Century bank account for personal use. In addition to submitting application paperwork 

to Medicare, he was responsible for submitting First Century’s required filings to state 

authorities.6

 Ms. Rinker testified that she told Mr. Adegboye that customers complained 

 

5 Mr. Adegboye wrote checks from the First Century account for the rent of Luant, 

Optimed, Providence, and Vitacare and for Ms. Rinker’s salary, as well as a check to 

Harco Heating and Air for services provided to Vitacare. Although a federal agent 

testified that there was no evidence First Century purchased supplies from Providence, 

First Century sent $56,000 via wire transfers to an account held by Providence. 

6

 On May 11, 2008, Mr. Ohaka emailed Mr. Adegboye to tell him that First Century had 

not submitted a renewal application required by the Oklahoma state health authority. 
7 

of not receiving their equipment or receiving equipment they did not order. 

 The Government argues that Mr. Adegboye’s First Century activities permit an 

inference that he knew about health care fraud because it would be unusual not to have 

such knowledge with his level of involvement. This argument goes too far. For example, 

Ms. Rinker was even more involved in running Mr. Ohaka’s businesses, including First 

Century, and she at most had a suspicion that Mr. Ohaka was committing health care 

fraud. See Rahseparian, 231 F.3d at 1264 (noting that “suspicion is insufficient to 

support an inference that [an individual] intended to join” a criminal scheme). 

 The majority opinion emphasizes that Mr. Adegboye was told that customers had 

complained about not receiving equipment. The problem, however, is that the 

Government did not present evidence that Mr. Adegboye knew anything about the 

volume of complaints. All businesses receive at least some customer complaints, and 

First Century was a new business that was just establishing its operations. The 

Government did not show that Mr. Adegboye knew enough about the complaints to 

determine they were a result of fraud instead of something more benign, such as slow or 

disorganized operational processes. 

5. False exculpatory statements to Medicare 

 First Century ceased operations in January 2009. Mr. Ohaka was indicted in July 

2009. At trial the Government presented an affidavit Mr. Adegboye sent to Medicare in 

September 2009 that understated Mr. Ohaka’s role at First Century. 

 After-the-fact statements to hide one’s involvement in illegal activity “are 
8 

admissible to prove circumstantially consciousness of guilt or unlawful intent.” United 

States v. Davis, 437 F.3d 989, 996 (10th Cir. 2006); see also United States v. Bailey, 327 

F.3d 1130, 1140 (10th Cir. 2003) (stating that “[i]ntent may be inferred from evidence 

that the defendant attempted to conceal activity,” from misrepresentations, and from 

knowingly making false statements). But such evidence has low probative value under 

our precedent. 

 Our decision in Rahseparian, 231 F.3d 1257, is instructive. We reversed 

defendant Jack Rahseparian’s convictions for money laundering, mail fraud, and 

conspiracy to commit mail fraud because the evidence was insufficient to show criminal 

intent. Id. at 1260. The case concerned Genesis Marketing, a telemarketing business 

through which sons Ardie and Steve defrauded customers by failing to deliver products 

and prizes to them. Id. The customers sent checks to a mailbox. Id. at 1261. Mr. 

Rahseparian retrieved the checks and deposited them in three bank accounts, two 

belonging to his business, and one established in his and Steve’s names. Id. He called 

Ardie almost every day to ask about how many checks to expect and the dollar amount. 

Id.

 Although Mr. Rahseparian facilitated the fraud by accepting and depositing the 

checks, and although he had frequent contact with his son, we held this was not enough to 

prove intent. The Government relied primarily on false exculpatory statements Mr. 

Rahseparian made to law enforcement officers when they first asked him about the 

source of the deposited funds. Id. He denied knowing anything about Genesis, the 
9 

mailbox, and the joint bank account, and stated falsely that he cashed Genesis checks for 

someone for whom he did catering events. Id. 

 We said there was “no evidence [Mr. Rahseparian] was aware of the 

misrepresentations being made to customers, or that they were not receiving their 

products or prizes.” Id. at 1263. We also said the “[f]alse exculpatory statements cannot 

by themselves prove the government’s case.” Id. The statements did “clearly support an 

inference that by then [he] had a suspicion of criminal activity.” Id. at 1264. “[E]ven if 

[he] were suspicious of his sons’ activities at the time he was depositing their checks, 

such a suspicion is insufficient to support an inference that he intended to join known 

criminal activity.” Id. 

 In his affidavit to Medicare explaining that he had asked the FBI to return First 

Century documents to him so that he could turn them over to Medicare, Mr. Adegboye 

described Mr. Ohaka as a “close friend” but falsely implied Mr. Ohaka had nothing to do 

with First Century. By this time, Mr. Adegboye knew that Mr. Ohaka had been indicted 

in Texas for health care fraud and therefore had reason to conceal that he was in business 

with Mr. Ohaka at First Century. Does this evidence show that Mr. Adegboye knew 

about Mr. Ohaka’s health care fraud at First Century when it occurred? Rahseparian 

teaches that false exculpatory statements made months after the alleged criminal activity 

ceased have limited probative value to show such knowledge. 

 Although we have recognized that false exculpatory statements can be evidence of 

consciousness of guilt, see United States v. Caldwell, 560 F.3d 1214, 1220 (10th Cir. 
10 

2009) (stating “the jury could infer Mrs. Caldwell’s guilty knowledge [of events taking 

place over three years before] if they disbelieved her exculpatory testimony”); Davis, 437 

F.3d at 996 (stating “false exculpatory statements [made eight days after a bank robbery 

to an FBI agent investigating it]. . . are admissible to prove circumstantially 

consciousness of guilt or unlawful intent”), such statements do not necessarily indicate 

knowledge of criminal activity at the time it occurred. Rather, as we noted in 

Rahseparian, such statements may indicate no more than an after-the-fact realization that 

the declarant, unbeknownst to him, may have been involved earlier in illegal activity, 

with the accompanying desire to distance himself from suspicion as much as possible. 

231 F.3d at 1264. Mr. Adegboye’s affidavit misstated Mr. Ohaka’s role at First Century, 

but it came almost a year after the fraudulent activity had ceased. It may show that Mr. 

Adegboye knew about the Medicare fraud “by then,” id., and that he may have been 

suspicious 12 months earlier, but it is not enough to support an inference of knowledge 

about the fraudulent billing when it was occurring. 

 The majority opinion suggests that evidence in the record shows that Mr. 

Adegboye made efforts to “cover up” First Century’s fraud. But apart from Mr. 

Adegboye’s Medicare affidavit discussed above, the evidence the majority cites does not 

demonstrate a cover up and does not go to Mr. Adegboye’s knowledge. For example, 

after Medicare informed First Century that its inventory was too low, Mr. Adegboye 

provided Medicare with invoices indicating that First Century had purchased inventory 

from other companies, including an invoice for $115,000 from Providence, which was 
11 

owned by Mr. Ohaka. Mr. Adegboye wrote a check from First Century’s account in the 

amount of $115,000 and deposited it directly into Providence’s account. 

 The majority infers from this that Mr. Adegboye was covering up First Century’s 

fraud. This inference might be reasonable if Mr. Adegboye had not actually delivered the 

funds to Providence, but he did so. The inference might also be reasonable if there was 

evidence Mr. Adegboye knew that Providence would not ultimately deliver the inventory, 

but there was no such evidence. Mr. Adegboye was in New York, and everyone agrees 

he had little involvement in First Century’s operations. These facts simply do not tell us 

anything about Mr. Adegboye’s knowledge of the fraud. 

B. Totality of the Circumstances 

 “Sufficiency of the evidence determinations are made by assessing the totality of 

the circumstances in the individual case.” Torres v. Mullin, 317 F.3d 1145, 1164 (10th 

Cir. 2003). The Government’s evidence painted a picture of Mr. Adegboye as a mostly 

absentee participant in a business for which he allowed his name to be used as a principal 

but in which Mr. Ohaka was in charge and actively managed operations. A jury could 

infer that Mr. Adegboye knew that (1) he was a straw owner and that Mr. Ohaka was 

running First Century; (2) First Century’s business served only Medicare beneficiaries; 

(3) First Century depended on Medicare reimbursements for its revenue; (4) Medicare 

had found deficiencies in its operations; (5) he misrepresented the true ownership and 

management of First Century to Medicare when First Century was seeking and 

maintaining Medicare enrollment approval and (6) later when he submitted an affidavit to 
12 

Medicare after operations had ceased; and (7) customers had complained about not 

receiving equipment. The Government also presented evidence that, while Mr. Ohaka 

and First Century were committing Medicare fraud, Mr. Adegboye paid bills, withdrew 

funds, and interacted with First Century employees, Mr. Rufai, and Mr. Ohaka.7

 

Of the foregoing, the Government’s case turns mostly on how Mr. Adegboye 

handled the application to enroll First Century as a Medicare provider. He listed only 

himself on the original application. Later he added Ms. Rinker and Ms. Unsell when 

Medicare inspectors told him to do so. Even though the enrollment form called for 

identification of managing employees and for updating the form, and even though Mr. 

Adegboye knew that Mr. Ohaka was managing First Century, Mr. Adegboye never listed 

Mr. Ohaka (Mr. Ohaka’s name did appear on an attachment to the original application). 

But even if a jury could reasonably infer that Mr. Adegboye knowingly concealed Mr. 

Ohaka’s identity from Medicare, could it further infer that Mr. Adegboye knew that Mr. 

Ohaka was falsely billing Medicare? The issue is very close, and the needed inference 

itself rests on an inference. 

 This is where the two key parts of the standard of review come into play. The first

 On July 6, 2009, well after First Century’s billing privileges had been revoked and just 

before Mr. Ohaka was indicted, Mr. Adegboye emailed Mr. Ohaka (copy to Mr. Rufai) a 

letter from the attorneys of First Century’s landlords about debts First Century owed. Mr. 

Adegboye told Mr. Ohaka that they needed to “sit down and tackle the issue like matured 

[sic] and responsible adults,” or they were “only postponing the evil day.” Government 

Trial Ex. # 31, Aplee. Suppl. Appx. at 586. This email may indicate that Mr. Adegboye 

expected Mr. Ohaka to help with First Century’s rent, but it does little or nothing to show 

that Mr. Adegboye knew of Mr. Ohaka’s fraudulent billing scheme.

part asks what a reasonable jury could find about Mr. Adegboye’s knowledge. A 

reasonable jury could find by inference that Mr. Adegboye knowingly concealed Mr. 

Ohaka’s name on the Medicare enrollment forms. From this inference and the other 

evidence, a reasonable jury could suspect and also possibly infer that Mr. Adegboye 

knew about Mr. Ohaka’s submitting false bills to Medicare. The second part of review 

asks whether a reasonable jury could draw this second inference beyond a reasonable 

doubt. An affirmative answer would establish the remaining essential element of the 

aiding and abetting offense—that Mr. Adegboye knew about Mr. Ohaka’s false billing 

scheme. The Government must present substantial evidence that a jury could draw this 

inference from the Medicare enrollment inference. Based on review and analysis of the 

record, and viewed in the light most favorable to the Government, the Government fell 

short. 

Adding the straw ownership scheme, customer complaints, and other evidence 

does not strengthen the Medicare application evidence as a basis to infer Mr. Adegboye’s 

knowledge of false billing, nor does it solve the problem that his activity in the business 

lacked an evidentiary connection to the Medicare billing.8

 His affidavit downplaying Mr. 

Ohaka’s role in First Century may support consciousness of Medicare fraud when he 

 

8 The customer complaint evidence is based on Ms. Rinker’s testimony, which fails to 

establish the number and types of complaints, what Mr. Ohaka told Ms. Rinker to tell Mr. 

Adegboye, what she actually told him, or how the complaints differed from delivery 

miscues that product supply businesses typically face, especially in the starting months of 

a new business. And she ultimately testified that she did not tell him about any 

“particular” complaints. Trial Tr. at 226, 249-50, 308-09, 312.

signed it, but the affidavit statements were made after Mr. Adegboye knew about Mr. 

Ohaka’s indictment for health care fraud in Texas and about one year after First Century 

last billed Medicare. 

 This case is similar to Rahseparian. In that case, we said the government’s 

evidence – that Mr. Rahseparian (1) served as the contact for the Genesis Marketing 

mailbox, (2) conducted Genesis’s banking through his own personal business accounts, 

thereby commingling funds and making them more difficult to trace, (3) talked daily with 

his son about incoming checks, (4) purchased “lead sheets” for Genesis using a cashier’s 

check rather than a business check, and (5) made false exculpatory statements to 

investigators months after the alleged fraud ended – was insufficient for a reasonable jury 

to find that he knew Genesis was committing telemarketing fraud. 

Like Mr. Rahseparian, Mr. Adegboye made false exculpatory statements to the 

government months (about a year) after the fraudulent activity had ended. The 

Rahseparian court said that the false exculpatory statements alone were insufficient. I 

would reach the same conclusion about Mr. Adegboye’s affidavit, which was less 

incriminating than Mr. Rasheparian’s statements to investigators. As in Rahseparian, the 

prosecution presented evidence in addition to Mr. Adegboye’s false exculpatory 

statement. Although that evidence may have been a bit stronger than in Rahseparian – 

the Medicare billing approval evidence in particular – it was, as in Rahseparian, 

insufficient to infer knowledge of the alleged billing fraud beyond a reasonable doubt.

Mr. Ohaka recruited Mr. Adegboye and Mr. Rufai to be the front men for his fraudulent 

business. It is possible that Mr. Adegboye was duped into thinking he had been given a 

legitimate business opportunity and later may have suspected the business was illicit in 

some way, especially after Mr. Ohaka had been indicted. On the other hand, as the 

indictment alleged, he may have been aware of Mr. Ohaka’s billing scheme and First 

Century’s fraudulent Medicare claims at the time of the criminal activity. But if the latter 

is true, the Government did not prove it beyond a reasonable doubt, directly or 

circumstantially. Mindful of the standard of review that applies to a sufficiency of the 

evidence challenge, I would reverse Mr. Adegboye’s conviction for aiding and abetting 

health care fraud.9

 

9 After arguing that the evidence was insufficient to support his conviction, Mr. 

Adegboye contends that the only explanation for his aiding and abetting convictions and 

his acquittal for conspiracy is that the jury was confused and mistaken on the law. This 

argument appears to attempt to reinforce Mr. Adegboye’s insufficiency of the evidence 

argument rather than stand as a separate issue. In particular, he argues that the jury held 

him strictly liable for the actions of First Century because he was responsible for its 

dealings as its owner and because he signed the Medicare applications. Because I would 

hold that the evidence was insufficient, the court need not reach this argument.
