ON APPEAL FROM THE 

UNITED STATES DISTRICT 

COURT FOR THE EASTERN 

DISTRICT OF KENTUCKY

BEFORE: SILER, GILMAN, and GIBBONS, Circuit Judges.

JULIA SMITH GIBBONS, Circuit Judge. Darmus Dalton was convicted of 

conspiracy to intentionally distribute and to possess with intent to distribute oxycodone in 

violation of 21 U.S.C. § 846. The district court sentenced him to 235 months’ imprisonment. 

On appeal, Dalton challenges his conviction and sentence. Because Dalton was not deprived of 

his right to a fair trial due to the cumulative effect of alleged improper expert opinion testimony 

and alleged prosecutorial misconduct, and because his sentence was not procedurally 

unreasonable, we affirm.

I.

From December 2009, Darmus “Bubby” Dalton sold oxycodone and other pills in 

Somerset, Kentucky. He sold pills directly to addicts. He sold pills to other dealers. And other 

dealers sold pills on his behalf.
No. 12-6170

United States v. Dalton

Dalton obtained oxycodone pills in two principal ways. First, he purchased pills from 

other dealers. Second, Dalton traveled to pain clinics in Florida and Georgia. On these trips, 

Dalton traveled with other persons whose expenses he financed. These persons obtained

oxycodone prescriptions from pain clinics and filled the prescriptions at nearby pharmacies. 

Dalton financed the trip expenses, doctor visits, and pharmacy charges. In exchange, Dalton

received approximately half of the pills obtained. Sometimes, in exchange for the financing, 

Dalton charged more: fifty pills plus half of the remainder of the prescription. Dalton would also 

pay persons to drive on these trips.

A federal grand jury indicted Dalton for conspiring with Craig West, Blake Gumm, 

William Padgett, Christi Combs, Joseph Stripling, and Andrea Ridner, between December 2009 

and February 11, 2011, to intentionally distribute, and to possess with intent to distribute, 

oxycodone, in violation of 21 U.S.C. § 846. The indictment also included a forfeiture count, 

seeking a $360,000 judgment representing the gross proceeds of the conspiracy.

After a three-day joint trial, a jury convicted Dalton, West, and Combs. Following an 

evidentiary hearing on Dalton’s objections to the presentence report (PSR) and the government’s 

forfeiture claim, the district court sentenced Dalton to 235 months’ imprisonment, a three-year 

term of supervised release, and ordered him to forfeit $200,000. Dalton timely appealed.

II.

On appeal, Dalton submits that the cumulative effect of improper expert opinion 

testimony and government misconduct during closing arguments violated his right to a fair trial. 

“‘The cumulative effect of errors that are harmless by themselves can be so prejudicial as to 

warrant a new trial.’” United States v. Adams, 722 F.3d 788, 832 (6th Cir. 2013) (quoting United 

States v. Sypher, 684 F.3d 622, 628 (6th Cir. 2012)). To obtain a new trial based upon 
No. 12-6170

United States v. Dalton

-3-

cumulative error, a defendant must show that the combined effect of individual harmless errors 

was so prejudicial as to render his or her trial fundamentally unfair. Id. Only the cumulative 

prejudicial effect of errors may undermine the fairness of a trial. United States v. Trujillo,

376 F.3d 593, 614 (6th Cir. 2004) (“‘[A] cumulative-error analysis should evaluate only the 

effect of matters determined to be error, not the cumulative effect of non-errors.’” (quoting 

United States v. Rivera, 900 F.2d 1462, 1471 (10th Cir. 1990))). Thus, when determining a 

cumulative-effect claim, the court determines if the defendant’s allegations of error have merit 

and, if so, considers whether the combined effect of the errors was so prejudicial as to warrant a 

new trial. See, e.g., id.; Baze v. Parker, 371 F.3d 310, 330 (6th Cir. 2004).

A.

Dalton first argues that the district court erred by admitting the expert testimony of 

Detective Randy Hunter regarding the pattern Hunter observed in unrelated oxycodoneconspiracy investigations in Kentucky. A “trial court’s determination whether [a] proffered 

expert opinion will assist the trier of fact to understand the evidence or to determine a fact in 

issue, is . . . review[ed] for abuse of discretion.” United States v. Jones, 107 F.3d 1147, 1151 

(6th Cir. 1997) (internal quotation marks and citation omitted). Under Federal Rule of Evidence 

702, a person with “specialized knowledge” qualified by his or her “knowledge, skill, 

experience, training, or education” may give opinion testimony if it “will help the trier of fact to 

understand the evidence or to determine a fact in issue.” Fed. R. Evid. 702. The proponent of an 

expert witness should pose qualifying and foundational questions before proceeding to elicit 

opinion testimony. United States v. Johnson, 488 F.3d 690, 698 (6th Cir. 2007). “Courts 

generally have permitted police officers to testify as experts regarding drug trafficking as long as 

the testimony is relevant and reliable.” Id. (citing United States v. Lopez-Medina, 461 F.3d 724, 
No. 12-6170

United States v. Dalton

-4-

742–43 (6th Cir. 2006)). And we “‘regularly allow[] qualified law enforcement personnel to 

testify on characteristics of criminal activity, as long as appropriate cautionary instructions are 

given, since knowledge of such activity is generally beyond the understanding of the average 

layman.’” Id. (quoting United States v. Swafford, 385 F.3d 1026, 1030 (6th Cir. 2004)); see also

United States v. Pearce, 912 F.2d 159, 163 (6th Cir. 1990) (“Law enforcement officers may 

testify concerning the methods and techniques employed in an area of criminal activity and to 

establish ‘modus operandi’ of particular crimes. Knowledge of such activity is generally 

‘beyond the understanding of the average layman.’” (quoting United States v. Espinosa, 827 F.2d 

604, 611 (9th Cir. 1987))). 

In Dalton’s trial, the government established that Detective Hunter had specialized 

knowledge regarding pill-trafficking conspiracies connecting eastern Kentucky and south 

Florida. After the government laid a foundation and began to elicit opinion testimony, Dalton 

objected that Hunter’s opinion would not assist the jury in determining a fact in issue. The 

government then laid a broader foundation, inquiring into Detective Hunter’s presentations at 

national law-enforcement conferences concerning pill-trafficking in eastern Kentucky. Detective 

Hunter then testified generally to operations of oxycodone conspiracies similar to the conspiracy 

alleged in this case. Hunter gave opinion testimony as to the source of oxycodone that he had 

seen in eastern Kentucky, the prevalence of particular kinds of pills, their respective street prices, 

the organizational structure of groups trafficking pills from south Florida to eastern Kentucky, 

the prevalence of cash-strapped pill abusers in these groups and the concomitant necessity of 

sponsors, the rate of return to the sponsor for financing the trips to Florida pain clinics, and the 

patterns of medical record-keeping at the pain clinics and pharmacies that supplied the 

prescriptions and pills. The district court denied Dalton’s oral motion to exclude this testimony, 
No. 12-6170

United States v. Dalton

-5-

concluding that it was helpful because the details of oxycodone trafficking are usually beyond 

lay understanding. Further, the district court gave appropriate cautionary instructions regarding 

Hunter’s testimony.

Relying on out-of-circuit case law, Dalton argues on appeal that expert testimony about 

patterns of drug-trafficking activity is not admissible for the purpose of bolstering the testimony 

of a cooperating witness. See United States v. Cruz, 981 F.2d 659, 663 (2d Cir. 1992). In Cruz, 

the Second Circuit held that the district court abused its discretion by allowing the expert 

testimony of a law enforcement special agent describing typical drug-trafficking operations in 

the Washington Heights neighborhood of New York and the function of a broker in drug 

trafficking between Washington Heights and the Albany area. Id. at 660. The Cruz court 

doubted that the agent’s testimony was helpful to the jury. It concluded that the testimony was 

impermissible because the government’s principal purpose was to bolster the testimony of a 

cooperating fact witness “where the [fact] witness’s version [of events] is not attacked as 

improbable or ambiguous evidence of such conduct” and where the expert witness’s “testimony 

logically adds nothing to the believability of the [fact] witness’s account.” Id. at 663. Leaning 

on Cruz, Dalton submits that the testimony of the fact witnesses as to the operation of the 

conspiracy was easily comprehensible and, hence, Detective Hunter’s opinion testimony 

impermissibly served only to bolster the testimony of the fact witnesses. 

Even if Cruz were precedent for this court, it would not control here. First, unlike in 

Cruz, Dalton attacked the credibility of the fact witnesses’ version of events—indeed, his theory 

of the case was that they had lied. Moreover, Sixth Circuit precedent permits law-enforcement 

officers to “testify concerning the methods and techniques employed in an area of criminal 

activity and to establish ‘modus operandi’ of particular crimes.” Pearce, 912 F.2d at 163 
No. 12-6170

United States v. Dalton

-6-

(finding, as here, that “[t]he trial court’s decision to permit the expert testimony occurred after all 

other evidence had been introduced”). Detective Hunter’s testimony was relevant for that 

purpose. He testified about how pill-trafficking conspiracies are established, how they operate, 

and how sponsorships are prevalent. It was not an abuse of discretion for the district court to 

conclude that the details of oxycodone trafficking—particularly the details concerning the 

necessity and development of sponsorship in pill-trafficking organizations—are not within the 

ambit of lay knowledge. See Johnson, 488 F.3d at 698. Thus, the district court did not err in 

concluding that Detective Hunter’s opinion testimony reasonably assisted the jury “to understand 

the evidence.” See Fed. R. Evid. 702. 

Dalton also contends that Hunter’s opinion testimony describing a previous investigation 

of a large-scale, pill-trafficking conspiracy (“Operation Flamingo Road”) accomplished 

indirectly what is prohibited to the government in closing arguments—namely, an exhortation to 

jurors to convict a defendant in an attempt to respond to a drug problem in their community. The 

government correctly points out that Dalton mischaracterizes Hunter’s testimony. Detective 

Hunter testified as to his participation in Operation Flamingo Road to establish his qualifications 

and to lay the foundation for his opinion testimony as to the operation of pill-trafficking 

conspiracies. His testimony regarding his involvement in prior investigations of similar 

conspiracies does not amount to a call for an eastern Kentucky jury to respond to the drug 

problem touching their community. Moreover, Hunter did not express an opinion on Dalton’s 

guilt, did not testify as to Dalton’s characteristics, did not remark on the credibility of the fact 

witnesses, and did not express an opinion on what the law requires—in short, Hunter did not 

intrude on the provinces of the jury or the court. Accordingly, the district court did not err in 

admitting Detective Hunter’s opinion testimony.
No. 12-6170

United States v. Dalton

B.

Dalton also submits that the government made flagrantly improper remarks during its 

rebuttal closing argument. We employ a two-step inquiry to determine whether prosecutorial 

misconduct occurred. United States v. Henry, 545 F.3d 367, 376 (6th Cir. 2008) (citing United 

States v. Francis, 170 F.3d 546, 549 (6th Cir. 1999)). First, we determine whether a statement 

was improper. If so, we then examine whether the statement was so flagrant as to warrant 

reversal. Id. We “consider[] four factors in determining whether a statement was flagrant: 

(1) whether the prosecutor’s remarks or conduct tended to mislead the jury or prejudice the 

defendant; (2) whether the remarks were isolated or extensive; (3) whether the remarks were 

accidentally or deliberately made; and (4) the overall strength of the evidence against the 

accused.” Id. (citing Francis, 170 F.3d at 549−50).

Dalton did not object at trial to the remarks he now challenges on appeal. Thus, his 

prosecutorial-misconduct claim is reviewed for plain error. Henry, 545 F.3d at 376. Plain-error 

review requires us “to determine whether ‘(1) an error occurred in the district court; (2) the error 

was obvious or clear; (3) the error affected defendant’s substantial rights; and (4) this adverse 

impact seriously affected the fairness, integrity, or public reputation of the judicial 

proceedings.’” Id. at 376−77 (quoting United States v. Emuegbunam, 268 F.3d 377, 406 (6th 

Cir. 2001)). “‘Only in exceptional circumstances in which the error is so plain that the trial 

judge and prosecutor were derelict in countenancing it will this court reverse a conviction under 

the plain-error standard.’” Id. (quoting Emuegbunam, 268 F.3d at 406).1

 

1 Because Dalton cannot establish that the district court erred in admitting Detective 

Hunter’s testimony, the court does not need to determine how to cumulate unpreserved error 

(reviewed for plain error) with preserved error (reviewed for harmless error). The Sixth Circuit

In his first claim of prosecutorial misconduct, Dalton contends that counsel for the 

government, AUSA Stephen Smith, improperly placed his own personal integrity at issue during 

the government’s rebuttal closing argument. Dalton points to the following remarks by the 

prosecutor:

Likewise, the suggestion to you that if Detective Janutolo was just not so lazy and 

was just not so incompetent, and that prosecutor over there wasn’t so coercive, 

then he’d played these audiotapes of these meetings with these witnesses, you’d 

find out the real truth. See, him and that detective, and according to Mr. Norfleet 

[Dalton’s counsel], there’s a conspiracy, and Steve Smith [the AUSA making this 

rebuttal argument] sits right in the middle of it, ladies and gentlemen, and he’s got 

a motive to make up on Christi Combs and Mr. West and Mr. Dalton. He wants 

to get them all convicted wrongfully. They’re innocent, but he’s going to coerce, 

he’s going to bribe and promise these witnesses something that he can’t even do. 

Because the judge already told you, he’s the one that’s going to sentence these 

people. And if you believe Mr. Norfleet’s version of these facts, you’ve got to 

believe that Mr. Smith and Detective Janutolo are part of a conspiracy to 

manufacture a case against these clients who are innocent and should walk freely 

out the doors of this courthouse.

In reply, the government contends that these remarks were made in response to Dalton’s 

counsel’s contentions made in closing argument that the government made “promises” and 

“coached” the witnesses. For example, Mr. Norfleet argued:

Now, you know, you’ve heard me a lot, and honestly, I probably got on your 

nerves somewhat when I would ask all the detectives, Did you record these 

statements? You know why I wanted to have the statements? I’d like to play 

them for you, and I’ll tell you. . . [why] I would like to play them for you. I 

would like to hear the promises that was made. I would like to hear how they was 

coached about who ultimately made the decision about the sentence, about what 

the judge has to consider to get there, and what this man can file to get a sentence 

reduction, and how the process works before this man files a sentence reduction. 

And it could have been done. . . . They’re not recorded for a reason. They don’t 

want the defense to have them, because it hurts them.

 

has not directly addressed this issue. United States v. Warman, 578 F.3d 320, 349 n.4 (6th Cir. 

2009).
No. 12-6170

United States v. Dalton

-9-

Even considering that AUSA Smith’s remarks were made in reply to Dalton’s comments, the 

injection of his personal integrity in rebuttal argument was arguably improper. In United States 

v. Young, the Supreme Court explained that “the prosecutor’s opinion carries with it the 

imprimatur of the Government and may induce the jury to trust the Government’s judgment 

rather than its own view of the evidence.” 470 U.S. 1, 18−19 (1985). Thus, it is improper for a 

prosecutor to assert his or her own credibility to bolster the credibility of a witness. It is also 

improper for the prosecutor to suggest that the prosecutor knows something that the jury does not 

know and thereby convey the impression that the jury should simply trust the government’s 

judgment. Hodge v. Hurley, 426 F.3d 368, 378 (6th Cir. 2005). Accordingly, the Fifth Circuit 

has held improper an unequivocal statement by a prosecutor that, for the jurors to believe the 

defendant’s account, they must believe in a government conspiracy. See United States v. Gracia, 

522 F.3d 597, 601−02 (5th Cir. 2008). In this case, the prosecutor lampooned Dalton’s attack on 

the credibility of the witnesses by suggesting that his theory of the case entailed that AUSA 

Smith himself was engaged in an illicit conspiracy to convict Dalton on false pretenses. By 

implying that this premise was ridiculous, the prosecutor indirectly suggested that he knew 

something the jurors did not (i.e., that there was no such conspiracy) and implied that the jury 

should trust the government’s judgment. 

The dispositive inquiry, however, is not whether AUSA Smith’s comments were 

improper, but whether the comments were so flagrant as to require reversal and so adverse that 

they seriously undermined the fairness of the judicial proceedings. Taken in context, AUSA 

Smith’s comments were not reversibly flagrant. We “afford wide latitude to a prosecutor during 

closing argument, analyzing disputed comments in the context of the trial as a whole and 

recognizing that inappropriate comments alone do not justify reversal where the proceedings 
No. 12-6170

United States v. Dalton

-10-

were ‘otherwise fair.’” Henry, 545 F.3d at 377 (quoting Young, 470 U.S. at 11); see also United 

States v. Hitow, 889 F.2d 1573, 1579 (6th Cir. 1989) (“Even if certain comments are found to be 

inappropriate, they . . . must be examined within the context of the trial to determine whether the 

prosecutor’s behavior amounted to prejudicial error.” (internal citation omitted)). “In order to

make an appropriate assessment . . . [this] court must not only weigh the impact of the 

prosecutor’s remarks, but must also take into account defense counsel’s opening salvo. Thus the 

import of the evaluation has been that if the prosecutor’s remarks were ‘invited,’ and did no 

more than respond substantially in order to ‘right the scale,’ such comments would not warrant 

reversing a conviction.” Young, 470 U.S. at 12−13.

We take into account defense counsel’s remarks that precipitated the government’s 

remarks. Id. at 12. In closing arguments, Dalton’s counsel made speculative remarks about 

unrecorded conversations between the prosecution and the fact witnesses concerning alleged 

promises of the government’s assistance in seeking sentencing reductions in exchange for 

inculpatory testimony. In response to these remarks, AUSA Smith’s comments that Dalton’s 

theory implies an incredible government conspiracy were, if not invited, then deliberately made 

to “right the scale.” See id. at 13. As made in response to Mr. Norfleet’s imputation of 

impropriety, we do not find that AUSA Smith’s remarks misled the jury to convict on a basis 

other than the evidence presented.

Nor did AUSA Smith’s comments constitute plain error. “Generally, an error does not 

affect substantial rights unless it is prejudicial—in other words, the error ‘must have affected the 

outcome of the district court proceedings.’” United States v. Bailey, 488 F.3d 363, 368 (6th Cir. 

2007) (quoting United States v. Olano, 507 U.S. 725, 734 (1993)). Dalton bears the burden of 

showing that the outcome of the trial would have been different but for AUSA Smith’s allusion 
No. 12-6170

United States v. Dalton

-11-

to a straw-man government conspiracy. See id. (“The defendant bears the burden of persuasion 

that the error was prejudicial.”). He fails in carrying that burden here. The testimony of Elridge, 

Robert Gumm, Blake Gumm, Hampton, Ard, Campbell, Fitzer, Stripling, and Burdine supports 

the conclusion that the jury verdict would not have been different. Hence, the prosecutor’s 

remarks cannot be said to rise to the level of plain error. His statements, although arguably

improper, “were not such as to undermine the fundamental fairness of the trial and contribute to 

a miscarriage of justice.” Cf. Young, 470 U.S. at 16.

Second, Dalton claims that AUSA Smith commented on Dalton’s failure to testify, 

thereby violating his Fifth Amendment privilege against self-incrimination. See Bowling v. 

Parker, 344 F.3d 487, 514 (6th Cir. 2003) (“The law is clear that the prosecution cannot 

comment on a defendant’s decision not to testify at trial.” (citing Griffin v. California, 380 U.S. 

609, 615 (1965))). Dalton highlights the following remark that the prosecution made during 

rebuttal closing argument:

[A]nd see this trash that Mr. Norfleet wants to call trash. It’s their trash, ladies 

and gentlemen. Those are their friends. These documents back there, these 

ledgers and diaries set forth that the trash that he’s talking about are their friends. 

I didn’t pick them. I didn’t come in here and script these witnesses. They got 

problems. They’ve admitted they had problems. They violated the law. They 

admitted they violated the law. Not everybody here’s admitted that. It’s going to 

be your decision whether or not they have.

In response, the government contends that the statement—“not everybody here’s admitted 

that”—referred to the credibility of Combs, which the prosecution addressed directly moments 

after making the challenged remark.

When a statement is challenged as an indirect comment on the defendant’s decision not to 

testify, we use four factors to evaluate such a statement: “‘1) Were the comments manifestly 

intended to reflect on the accused’s silence or of such a character that the jury would naturally 
No. 12-6170

United States v. Dalton

-12-

and necessarily take them as such; 2) were the remarks isolated or extensive; 3) was the evidence 

of guilt otherwise overwhelming; 4) what curative instructions were given and when.’” Bowling, 

344 F.3d at 514 (quoting Lent v. Wells, 861 F.2d 972, 975 (6th Cir. 1988)). Applying this 

framework, the prosecution’s statement does not rise to constitutional error. It is not manifest 

that the comment was intended to reflect on Dalton’s decision not to testify. Nor is the character 

of the passing remark so pronounced that the jury naturally and necessarily would have 

understood the remark as a comment on Dalton’s silence. Further, the challenged statement was 

isolated, and the evidence of Dalton’s guilt was strong, supported by the testimony of no less 

than eight fact witnesses. The prosecutor therefore did not violate Dalton’s privilege against 

self-incrimination as alleged by Dalton.

C.

In sum, Dalton’s cumulative-error claim fails; there are no errors to cumulate. Dalton 

cannot establish that the district court erred by admitting Detective Hunter’s opinion testimony. 

Nor can Dalton show that the prosecutor’s remarks during rebuttal closing argument were plain 

error.

III.

Dalton additionally challenges the procedural reasonableness of his 235-month sentence 

on appeal. The presentence report (PSR) found that Dalton was responsible for 

84,900 milligrams of oxycodone—the equivalent of 568.83 kilograms of marijuana—and 

determined that, pursuant to USSG § 2D1.1(c)(6), Dalton’s offense had a base level of 28. The 

PSR then found that Dalton was an organizer or leader of a criminal activity that involved five or 

more participants and was otherwise extensive. Accordingly, the PSR added four levels pursuant 

to USSG § 3B1.1(a) for a total offense level of 32. The PSR calculated that Dalton’s criminal 
No. 12-6170

United States v. Dalton

-13-

history score was six, establishing a criminal history category of III. Both the government and 

Dalton objected to the drug quantity determined by the PSR, and Dalton objected to the fourlevel increase for being an organizer and leader in the conspiracy. Dalton also objected to his 

guilt, the assessment of two criminal history points for committing the instant offense while 

under a sentence for third-degree rape, and the suggestion that there was an aggravating factor to 

justify an above-guidelines sentence.

At the sentencing proceeding, the district court found that the government established by 

a preponderance of the evidence that Dalton was responsible for 200,000 milligrams of 

oxycodone. The district court primarily based this finding on Hampton’s trial testimony and 

emphasized that the 200,000-miligram quantity was conservative. Accordingly, the district court 

sustained the government’s objection and overruled Dalton’s drug-quantity objection to the PSR.

Turning to the four-level enhancement, the district court overruled Dalton’s objection, 

concluding that Dalton was an organizer or leader “based on the evidence presented at trial,” and 

applied the four-level increase pursuant to USSG § 3B1.1(a). The district court then denied 

Dalton’s criminal-history-points objection as moot, and adopted the PSR “with the previous 

modifications.” The district court determined that Dalton’s offense merited a total offense level 

of 36 and a criminal history category of III, and accordingly was subject to a guidelines range of 

235 to 293 months. The district court then heard allocution as to the appropriate sentence, 

considered the sentencing factors under 18 U.S.C. § 3553(a), and imposed a bottom-of-the-range 

sentence of 235 months.

On appeal, Dalton claims the sentence was procedurally unreasonable because the district 

court improperly calculated the guidelines range and based the sentence on clearly erroneous 

facts. Specifically, Dalton lodges two procedural-reasonableness challenges: First, he claims 
No. 12-6170

United States v. Dalton

-14-

that the district court’s drug-quantify finding was erroneous. Second, he disputes the four-level, 

aggravating-role enhancement applied pursuant to USSG § 3B1.1.

A.

We review criminal sentences for both substantive and procedural reasonableness. Gall 

v. United States, 552 U.S. 38, 51 (2007). “Reasonableness is determined under the deferential 

abuse-of-discretion standard.” United States v. Battaglia, 624 F.3d 348, 350 (6th Cir. 2010). In 

determining procedural reasonableness, one factor this court assesses is “whether the district 

court properly calculated the Guidelines range.” Id. at 350–51. If the district court misinterprets 

the guidelines or miscalculates the guidelines range, then the resulting sentence is procedurally 

unreasonable. United States v. Bolds, 511 F.3d 568, 579 (6th Cir. 2007). “The court’s legal 

interpretation[s] of the Guidelines are reviewed de novo, but its factual findings are reviewed 

under the clearly-erroneous standard.” Battaglia, 624 F.3d at 351. “And the government bears 

the burden to ‘prove, by a preponderance of the evidence, that a particular sentencing 

enhancement applies.’” United States v. Stubblefield, 682 F.3d 502, 510 (6th Cir. 2012) (quoting 

United States v. Dupree, 323 F.3d 480, 491 (6th Cir. 2003)).

We review a district court’s drug-quantity determination as a factual finding under the 

clearly erroneous standard. United States v. Jeross, 521 F.3d 562, 570 (6th Cir. 2008) (citing

United States v. Sandridge, 385 F.3d 1032, 1037 (6th Cir. 2004)). If the exact amount of drugs is 

undetermined, “an estimate will suffice, but . . . a preponderance of the evidence must support 

the estimate.” United States v. Walton, 908 F.2d 1289, 1302 (6th Cir. 1990); see also United 

States v. Hernandez, 227 F.3d 686, 699 (6th Cir. 2000) (“Approximations are completely 

appropriate.”). A district court may not “hold a defendant responsible for a specific quantity of 

drugs unless the court can conclude the defendant is more likely than not actually responsible for 
No. 12-6170

United States v. Dalton

-15-

a quantity greater than or equal to the quantity for which the defendant is being held 

responsible.” Walton, 908 F.2d at 1302; see also Sandridge, 385 F.3d at 1037 (holding that “the 

court may make an estimate supported by competent evidence, but that the evidence supporting 

the estimate must have a minimal level of reliability beyond mere allegation, and the court 

should err on the side of caution in making its estimate” (internal quotation marks omitted).

Further, the district court’s estimate may be based upon physical evidence (such as seized 

drugs) or testimonial evidence. United States v. Pruitt, 156 F.3d 638, 647 (6th Cir. 1998). 

“[T]estimonial evidence from a coconspirator may be sufficient to determine the amount of 

drugs for which another coconspirator should be held accountable.” United States v. Swanberg,

370 F.3d 622, 625 (6th Cir. 2004) (quoting Hernadez, 227 F.3d at 697). This court “afford[s] the 

district court’s credibility determinations regarding witness testimony great deference.” United

States v. Esteppe, 483 F.3d 447, 452 (6th Cir. 2007). “Clear error will not be found where two 

permissible views of the evidence exist.” Jeross, 521 F.3d at 570 (citing Anderson v. City of 

Bessemer, 470 U.S. 564, 573−74 (1985)). And “a district court’s approximation of drug quantity 

is not clearly erroneous if it is supported by competent evidence in the record.” Id. (citing 

United States v. Brannon, 7 F.3d 516, 520 (6th Cir. 1993)).

Here, a preponderance of evidence supports the district court’s conservative estimation 

that Dalton was responsible for 200,000 milligrams of oxycodone. At the sentencing hearing, 

the district court heard the testimony of Detective Anthony Janutolo. Janutolo subpoenaed the 

available records of medical providers under investigation and created a summary thereof. 

Janutolo testified that those records demonstrate that, over a five-month period, Dalton was on 

average responsible for 16,500 milligrams per month. The district court then credited 

Hampton’s testimony that he and Dalton travelled together to Florida fifteen to twenty times to

obtain oxycodone. Extrapolating from the average milligrams acquired per month and a 

conservative estimate of the number of trips that Hampton and Dalton took to obtain oxycodone, 

the district court estimated that Dalton was responsible for 202,500 milligrams.2

Moreover, the record contains ample evidence of quantities of oxycodone for which 

Dalton was responsible apart from the district court’s extrapolation based on the medical records 

and Hampton’s testimony. For example, based on trial testimony, Detective Janutolo estimated 

that Robert Gumm sold between “102,000 to 136,000 milligrams” of oxycodone on behalf of 

Dalton over the period from November 2009 to April 2010. Detective Janutolo also estimated 

Blake Gumm purchased between “19,840 to 23,680” milligrams from Dalton. In addition, 

Eldridge bought 80-milligram tablets from Dalton “on a regular basis” from February 2010. 

Hampton saw Dalton purchase 300 pills from West. And Campbell traded his motorcycle to 

Dalton for twenty 80-milligram pills. The district court considered all of this record evidence, 

made an estimation “out of an abundance of caution,” and found Dalton responsible for 200,000 

milligrams.

Dalton now argues that the district court improperly extrapolated its estimation of the 

quantity of oxycodone for which he was responsible. He specifically contends that the district 

court’s reliance on Hampton’s testimony as to the number of trips Dalton took to Florida 

(fifteen) was erroneous. First, Dalton submits that Hampton’s testimony was not credible 

because Hampton admitted he was using oxycodone on a daily basis and during his direct and

Excluding those co-conspirators whom Dalton sponsored, Detective Janutolo’s 

summary indicates that Dalton himself received oxycodone four times: On April 23, 2010, he 

obtained 180 oxycodone 30-milligram pills; on May 21, 2010, he obtained 210 oxycodone 30-

milligram pills; on June 21, 2010, he obtained 240 oxycodone 30-milligram pills; and on July 21, 

2010, he obtained 240 oxycodone 30-milligram pills.

cross examinations at trial he could not answer various questions because his memory was 

impaired by drug use. But the district court found Hampton’s testimony “corroborated,” “never 

impeached,” and “extremely credible.” This determination is afforded great deference. See 

Esteppe, 483 F.3d at 452. Moreover, testimonial evidence from Hampton, one coconspirator, 

can be sufficient to determine the quantity of drugs for which Dalton, another coconspirator, is 

responsible. See Swanberg, 370 F.3d at 625.

Dalton also contends that Hampton’s testimony does not establish that Dalton made at 

least fifteen trips to Florida to obtain oxycodone. Dalton argues that when Hampton estimated 

making fifteen to twenty trips, Hampton gave his answer in response to a leading question and 

that other portions of his testimony make clear that the estimation actually referred to the total 

number of trips he had made either on his own or with others. The record, however, does not 

support Dalton’s interpretation. During direct examination, Hampton responded to AUSA 

Smith’s straightforward question about the number of visits Hampton and Dalton made together: 

“Q. And how many trips do you think you made to Florida with Mr. Dalton for the purpose of 

getting these oxycodone pills? A. I don’t know the exact amount, anywhere from fifteen to 

twenty probably.” Dalton attempts to equivocate Hampton’s estimation of the number of trips 

that Dalton took to Florida to obtain oxycodone with Hampton’s testimony to the percentage of 

times that Dalton sponsored Hampton on their joint trips. But those are different inquiries, and 

Hampton’s testimony regarding the latter does not call into question the district court’s reliance 

on his testimony that Dalton made at least fifteen trips to Florida.

The district court’s conservative estimate that Dalton was responsible for 200,000 

milligrams of oxycodone was supported by competent evidence in the record. Therefore, it is 

not clearly erroneous.

B.

Next, Dalton challenges the four-level, aggravating-role enhancement applied due to his 

role as an organizer or leader of a criminal activity. See USSG § 3B1.1(a). We review a 

sentencing court’s factual findings regarding a defendant’s role in a conspiracy for clear error. 

Hernandez, 227 F.3d at 699. Whether these facts warrant a sentence enhancement pursuant to 

§ 3B1.1(a) is a legal conclusion subject to de novo review. Id. (citing United States v. GortDiDonato, 109 F.3d 318, 320 (6th Cir. 1997)). “To apply the § 3B1.1 enhancement, the 

government must establish, by a preponderance of the evidence, the elements of § 3B1.1.” GortDidonato, 109 F.3d at 320 (citing United States v. Ledezma, 26 F.3d 636, 644 (6th Cir. 1994)).

USSG § 3B1.1(a) calls for a four-level increase “[i]f the defendant was an organizer or 

leader of a criminal activity that involved five or more participants or was otherwise extensive.” 

USSG § 3B1.1(a). USSG § 3B1.1 commentary application note 2 provides that to qualify for the 

enhancement, a defendant must have been the organizer or leader of one or more participants in 

the criminal activity. USSG § 3B1.1, comment. (n.2); see also United States v. Baker, 559 F.3d 

443, 449 (6th Cir. 2009) (enhancement requires only that defendant supervised or managed “one

of the five or more other participants” (quoting United States v. Robinson, 503 F.3d 522, 529 

(6th Cir. 2007))). Application note 4 provides that “[f]actors the court should consider include 

the exercise of decision making authority, the nature of participation in the commission of the 

offense, the recruitment of accomplices, the claimed right to a larger share of the fruits of the 

crime, the degree of participation in planning or organizing the offense, the nature and scope of 

the illegal activity, and the degree of control and authority exercised over others.” USSG 

§ 3B1.1, comment. (n.4). Application note 4 also makes clear that there can “be more than one 

person who qualifies as a leader or organizer of a criminal association or conspiracy.” Id.
No. 12-6170

United States v. Dalton

-19-

The district court correctly applied the § 3B1.1(a) sentencing enhancement. First, the 

conspiracy involved five or more participants. Four codefendants pled guilty. Two 

codefendants were found guilty by the jury. 

Second, the record supports the district court’s conclusion that Dalton was an organizer 

or leader of the conspiracy. Dalton played the part of an organizer because he financed the travel 

expenses of co-conspirators to Florida for the purpose of obtaining oxycodone. He covered trip 

expenses, doctor visits, and pharmacy charges of several co-conspirators. He organized and paid 

a co-conspirator to drive him to Florida for the purpose of obtaining oxycodone. Dalton also 

claimed the right to a larger share of the fruits of the conspiracy, collecting fifty percent or more 

of the pills obtained by the co-conspirators whom he sponsored. Dalton sold some of the pills he 

obtained to other dealers, and other dealers sold pills on his behalf.

Dalton submits that the four-level enhancement does not apply because United States v. 

Ward held “that ‘the mere fronting’ of [drugs] alone is insufficient to support finding a 

management relationship.’” 37 F.3d 243, 248 (6th Cir. 1994) (quoting United States v. Possick, 

849 F.2d 332, 336 (8th Cir. 1988)). The Ward court noted that “fronting” drugs is merely a 

variant of a traditional buyer-seller relationship and, by itself, does not establish a drugsupplier’s leadership or organizational role. Id. Dalton suggests that there is no difference 

between the “fronting” of drugs and his activity in this case. Ward, however, does not guide our

decision. First, Ward noted that “[t]he government provided no evidence that Ward set prices or 

arranged drug transactions.” Id. Here, Dalton arranged numerous expeditions to Florida to 

obtain oxycodone, which he later sold or had sold on his behalf in Kentucky. Second, Dalton did 

more than merely “front” drugs. See id. Dalton organized the Florida oxycodone expeditions, 

financed the up-front costs, and, in at least one case, paid for a co-conspirator to work as a driver. 
No. 12-6170

United States v. Dalton

Dalton’s financing supports the four-level enhancement. See United States v. Bates, 78 F.3d 

585, 1996 WL 84631, at *4 (6th Cir. 1996) (unpublished table disposition) (affirming 

defendant’s four-level enhancement under § 3B1.1(a) where defendant financed an out-of-state 

trip to obtain illegal drugs and provided expense money). Moreover, but for his sponsorship and 

leadership some of the drug transactions forming part of the conspiracy would not have 

occurred.3 Therefore, the district court did not err in applying the four-level enhancement.

Because the district court’s conservative estimate that Dalton was responsible for 200,000 

milligrams of oxycodone was supported by competent evidence in the record and because the 

district court did not err in applying the aggravating-role sentencing enhancement, Dalton cannot 

show that the 235-month sentence was procedurally unreasonable.

IV.

For the foregoing reasons, we affirm Dalton’s conviction and sentence.

 

3 Burdine’s testimony is particularly illuminating: “To begin with, there was no 

agreement between us because originally the deal was that I would drive; that was my primary 

goal or responsibility, was to drive. And once we were about half-way there, Mr. Dalton, 

through conversation with me, realized that I had a current MRI, and asked if I wanted to have 

him pay for me to be seen, and if so, you know, then I got my prescriptions, we would make 

arrangements after that. But I’m not sure if the arrangements were made prior or after, but I do 

know that he suggested or said that he takes 50 off the top and then half of what’s left.”
