CR 2023-01-0233-B

DECISION AND JOURNAL ENTRY

Dated: September 11, 2024

SUTTON, Presiding Judge.

{¶1} Appellant, the State of Ohio, appeals from two orders of the Summit County Court 

of Common Pleas, excluding testimony and evidence the State sought to introduce at the trials of 

Appellees, Demonte and Demetrius Carr (“the Carrs”). This Court reverses.

I.

{¶2} The Carrs were each indicted on charges of aggravated murder, murder, felony 

murder, felonious assault, having weapons under disability, and multiple firearm specifications. 

Demonte Carr was indicted in Criminal Case No. CR2023-01-0233(A). Demetrius Carr was 

indicted in Criminal Case No. CR2023-01-0233(B). The State theorized that the Carrs murdered 

J.A. the day after he murdered their brother. It sought to prove its theory through a report generated 

by CyberCheck and testimony from Adam Mosher, the creator of that software. The report 

purported to show that (1) J.A. was present in the area where the Carrs’ brother was murdered 
2

 

around the time of his death, and (2) the Carrs were present in the area where J.A. was murdered 

around the time of his death. The defense received a copy of the CyberCheck report in discovery.

{¶3} On June 7, 2023, the attorneys for Demonte Carr sent a letter to the State. The letter 

requested information about CyberCheck and Mr. Mosher. It included requests for the sources, 

data, and programs CyberCheck used to generate its report, including any proprietary machine 

learning software, artificial intelligence software or algorithms, proprietary code structures, third 

party open source intelligence applications, and data gathering APIs. Defense counsel reserved 

the right to file a motion to compel if the State failed to provide the requested items.

{¶4} On September 20 and 21, 2023, respectively, the Carrs filed nearly identical 

motions to compel. They moved to compel the State to provide them with the information 

Demonte Carr had requested in July. They argued the information was necessary to properly 

evaluate a Daubert and/or suppression challenge and to help their experts prepare for trial. Without 

access to Mr. Mosher’s software, they argued, their experts were unable to evaluate his work and 

the conclusions reached in the CyberCheck report. They asked the trial court to hold a hearing 

and exclude the CyberCheck evidence if the State failed to respond to the discovery request. 

{¶5} The trial court held a motions hearing at which the State, defense counsel for each 

of the Carrs, and Mr. Mosher appeared. The hearing took place on September 29, 2023, six days 

before the trial was set to commence in both cases. At the conclusion of the hearing, the trial court 

notified the State that it would be granting the motions to compel. It gave the State 48 hours to 

provide the requested discovery to defense counsel. The court later journalized its order.

{¶6} The State filed a written response to the trial court’s order. The State indicated that 

the items defense counsel had requested were not in its possession. The State also indicated that 

the Carrs had made no attempt to subpoena those items directly from Mr. Mosher/CyberCheck, 
3

 

the third-party private vendor in possession of the requested items. The State argued the only 

appropriate discovery sanction, if any, was for the trial court to continue the trial and allow the 

Carrs to subpoena the information they needed directly from Mr. Mosher/CyberCheck. 

{¶7} The trial court reviewed the State’s written response and issued an identical order 

in both cases. Citing Crim.R. 16(L)(1), the court excluded any evidence regarding CyberCheck 

from the scheduled trial. The State immediately appealed from the trial court’s orders in each case. 

This Court consolidated the two appeals for briefing, argument, and decision. 

{¶8} The State’s appeals are now before us. The State assigns one error for review. 

II.

ASSIGNMENT OF ERROR

THE TRIAL COURT ABUSED ITS DISCRETION BY EXCLUDING 

TESTIMONY AND ASSOCIATED EVIDENCE FROM THE CYBERCHECK 

REPORT.

{¶9} In its sole assignment of error, the State argues the trial court abused its discretion 

when it excluded the CyberCheck evidence based on a perceived violation of Crim.R. 16. For the 

following reasons, we sustain the State’s argument.

{¶10} Crim.R. 16 governs discovery in criminal cases. The rule is designed “to provide 

all parties in a criminal case with the information necessary for a full and fair adjudication of the 

facts, to protect the integrity of the justice system and the rights of defendants, and to protect the 

well-being of witnesses, victims, and society at large.” Crim.R. 16(A). “The rule aims ‘‘to prevent 

surprise and the secreting of evidence favorable to one party.’” State v. Huguley, 2017-Ohio-8300, 

¶ 16 (9th Dist.), quoting State v. Darmond, 2013-Ohio-966, ¶ 19, quoting Lakewood v. Papadelis, 

32 Ohio St.3d 1, 3 (1987).

{¶11} Under Crim.R. 16(K), a party who wishes to introduce expert testimony must 

supply opposing counsel with a summary of their expert’s qualifications and “a written report 

summarizing the expert witness’s testimony, findings, analysis, conclusions, or opinion . . . .” 

Crim.R. 16 also gives defendants the right to have copies or photographs of certain items “which 

are material to the preparation of a defense, or are intended for use by the prosecuting attorney as 

evidence at the trial, or were obtained from or belong to the defendant, within the possession of, 

or reasonably available to the state, subject to the provisions of this rule . . . .” Crim.R. 16(B). 

The rule “requires the state to produce only items in the prosecutor’s custody, and it is sufficient 

to inform the defendant of the whereabouts of documents in possession of another, if such 

documents are to be used against the accused at trial.” State v. Luskin, 1990 WL 203479, *2 (9th 

Dist. Dec. 12, 1990).

{¶12} If a party fails to comply with Crim.R. 16 or a discovery order of the court, “the 

court may order such party to permit the discovery or inspection, grant a continuance, or prohibit 

the party from introducing in evidence the material not disclosed, or it may make such other order 

as it deems just under the circumstances.” Crim.R. 16(L)(1). “[A] trial court must inquire into the 

circumstances of the alleged violation of Crim.R. 16 and must impose the least severe sanction 

consistent with the purpose of the discovery rules.” State v. Darmond, 2013-Ohio-966, ¶ 27. The 

court also should consider: “(1) whether the failure to disclose was a willful violation of Crim.R. 

16, (2) whether foreknowledge of the undisclosed material would have benefited the accused in 

the preparation of a defense, and (3) whether the accused was prejudiced.” Id. at ¶ 35.

{¶13} “We review a trial court’s decision regarding a Crim.R. 16 discovery violation for 

an abuse of discretion.” State v. Pieronek, 2019-Ohio-4305, ¶ 20 (9th Dist.). An abuse of 

discretion implies that the trial court’s attitude was unreasonable, arbitrary, or unconscionable. 
5

 

Blakemore v. Blakemore, 5 Ohio St.3d 217, 219 (1983). “A trial court may abuse its discretion 

where it fails to engage in a sound reasoning process.” Pieronek at ¶ 20.

{¶14} In support of their respective motions to compel, the Carrs produced (1) the 

discovery request Demonte Carr sent to the State on June 7, 2023, (2) the curriculum vitae of their 

experts, (3) a transcript from a hearing in State of Ohio v. Deshawn Coleman, and (4) various 

emails, affidavits, and filings from other court cases. The third and fourth items were offered to 

establish credibility concerns about Mr. Mosher’s qualifications, experience, and prior sworn 

testimony in other matters. The defense also informed the court that a different trial judge in 

another Summit County case had recently issued a ruling about CyberCheck evidence. The trial 

court was aware of the ruling and noted that “[t]he decision was that . . . CyberCheck had to turn 

over the stuff or it couldn’t be used.”

{¶15} The prosecutor informed the trial court that the State had complied with all 

discovery requests by providing defense counsel with the evidence currently in the State’s 

possession. The court did not doubt the veracity of that representation but asked whether 

CyberCheck would be turning over the information the defense had requested. The State 

responded that CyberCheck/Mr. Mosher had yet to be subpoenaed or ordered by the court to do 

so. The State also argued that Mr. Mosher’s hypothetical refusal to comply with a future subpoena 

or court order would be an action outside the State’s control. The trial court responded that it was 

the State’s obligation to issue any required subpoenas, as the State was the party seeking to admit 

the CyberCheck evidence.

{¶16} As discussions at the motions hearing continued, Mr. Mosher notified the court that 

the State had asked him for the information requested in the motion to compel. The trial court 

then placed Mr. Mosher under oath. Mr. Mosher testified that he was “getting confused on two 
6

 

different things” because he also had been asked to divulge information about CyberCheck in 

another pending case. He testified that, in the other case, he had offered to physically meet with 

the defendant’s experts “where we would spend days, and they can see how the algorithms and 

how the technology works.” He indicated that he made that offer because he was unwilling to 

“blindly send [that information] off, even under a protective order . . . .” The State noted that the 

defense was requesting propriety information. It also noted that the defense had not requested a 

Daubert hearing to test Mr. Mosher’s methodologies or his qualifications.

{¶17} The trial court acknowledged that the information the defense sought was not in the 

State’s possession. Nevertheless, it indicated that it would not admit the CyberCheck evidence at 

trial without the defense being given the requested information. The trial court gave the State 48 

hours to provide that information to defense counsel. When the State failed to comply with that 

order, the court excluded the CyberCheck evidence.

{¶18} Having reviewed the record, we must conclude that the trial court abused its 

discretion when it excluded the CyberCheck evidence pursuant to Crim.R. 16(L)(1). Initially, we 

note that only Demonte Carr sent a discovery request to the State on June 7, 2023. The request 

was sent by his attorneys, in his name, citing only his criminal case number. There is no indication 

in the record that his brother, Demetrius Carr, ever sent the State a written demand requesting the 

CyberCheck evidence. When Demetrius Carr filed a motion to compel, he cited his brother’s 

request for discovery. Yet, Crim.R. 16 only requires the State to provide discovery “[u]pon receipt 

of a written demand for discovery by the defendant . . . .” (Emphasis added.) Crim.R. 16(B). It 

is unclear to this Court how the State could fail to comply with a discovery request in the case of 

Demetrius Carr when that request was never made. See Papadelis, 32 Ohio St.3d at 3 (“Crim.R. 

16 contemplates an informal step – that being the demand or written request for discovery of one 
7

 

party upon another party.”). Because no one raised this issue in the trial court, however, we merely 

note the discrepancy in conducting our review. 

{¶19} No one has suggested that the State willfully violated Crim.R. 16 by refusing to 

turn over the information the Carrs requested. See Darmond, 2013-Ohio-966, at ¶ 35. It is 

undisputed that the State gave the Carrs all the information it had in its possession. The question 

is whether the additional information the Carrs sought was “reasonably available to the state” even 

though it was not in the State’s immediate possession. Crim.R. 16(B). 

{¶20} The general rule in this district is that the State only must produce items in its 

possession and “inform the defendant of the whereabouts of documents in possession of another, 

if such documents are to be used against the accused at trial.” Luskin, 1990 WL 203479, at *2 (9th 

Dist.). Yet, the role Mr. Mosher and CyberCheck play is less than clear, given that CyberCheck 

is a law-enforcement-only tool specifically designed to aid the State in conducting criminal 

investigations. This Court is mindful that even private entities can engage in state action in certain 

instances. See, e.g., State ex rel. Ohio AFL-CIO v. Ohio Bur. of Workers’ Comp., 2002-Ohio6717, ¶ 13 (drug testing conducted by private employers to aid the State in determining workers’ 

compensation eligibility constituted state action). The trial court did not expressly state why it 

determined the information was reasonably available to the State, but that determination is implicit 

in the trial court’s order to exclude the evidence. If CyberCheck is acting as an instrumentality of 

the State, an argument exists that its data, algorithms, and software ought to be deemed reasonably 

available to the State. However, we need not decide that issue to resolve this appeal because, even 

assuming the State failed to satisfy its obligations under Crim.R.16, the record reflects the trial 

court did not engage in a sound reasoning process when it excluded the State’s evidence. See 

Pieronek, 2019-Ohio-4305, at ¶ 20 (9th Dist.).

{¶21} As previously noted, a trial court must consider the circumstances behind any 

alleged Crim.R. 16 violation and “must impose the least severe sanction consistent with the 

purpose of the discovery rules.” Darmond, 2013-Ohio-966, at ¶ 27. The exclusion of the State’s 

evidence was not the least severe sanction available to the court under the circumstances herein. 

Although Demonte Carr requested the CyberCheck evidence four months before trial, the Carrs 

waited until two weeks before trial to file their motions to compel. They never notified the court 

there was an issue with discovery before that point, so there was no prior discovery order 

commanding the State to produce that information. The Carrs also never asked for a Daubert

hearing or moved to suppress the evidence. Moreover, neither Mr. Mosher, nor CyberCheck was 

ever subject to a subpoena or court order to produce the information Demonte Carr sought to elicit. 

Compare Cincinnati v. Ilg, 2014-Ohio-4258, ¶ 7-9 (defendant subpoenaed the Ohio Department 

of Health and the program administrator for alcohol and drug testing when the prosecutor did not 

produce specific records from the breathalyzer machine used to test his blood alcohol 

concentration). Mr. Mosher did note that he had offered different criminal defense attorneys in 

Summit County the opportunity to have their experts meet with him, review his software, and see 

how it worked. It is unclear from the record whether he would have extended the same offer to 

the attorneys in this case or whether such a meeting would have sufficed. That option was never 

explored. Nor were the options of a continuance for the purpose of issuing subpoenas to Mr. 

Mosher/CyberCheck or scheduling a Daubert hearing. The court only gave the State 48 hours to 

comply with the discovery request and immediately excluded the evidence when the State failed 

to comply. Compare State v. Woods, 2014-Ohio-4429, ¶ 21 (4th Dist.). Under the foregoing 

circumstances, we must conclude that the court abused its discretion by doing so. Accordingly, 

the State’s sole assignment of error is sustained.

III.

{¶22} The State’s sole assignment of error is sustained. The judgments of the Summit 

County Court of Common Pleas are reversed, and the causes are remanded for further proceedings 

consistent with the foregoing opinion.

Judgments reversed,

and causes remanded.

There were reasonable grounds for this appeal.

We order that a special mandate issue out of this Court, directing the Court of Common 

Pleas, County of Summit, State of Ohio, to carry this judgment into execution. A certified copy 

of this journal entry shall constitute the mandate, pursuant to App.R. 27.

Immediately upon the filing hereof, this document shall constitute the journal entry of 

judgment, and it shall be file stamped by the Clerk of the Court of Appeals at which time the period 

for review shall begin to run. App.R. 22(C). The Clerk of the Court of Appeals is instructed to 

mail a notice of entry of this judgment to the parties and to make a notation of the mailing in the 

docket, pursuant to App.R. 30.

Costs taxed to Appellees.
