Civil Appeal from the Cuyahoga County Court of Common Pleas Case No. CR-16-608045-A

SEAN C. GALLAGHER, J.:
Michael Riley appeals the denial of his application for postconviction
DNA testing, in which he claims advances in DNA collection techniques could lead to the detection of DNA material that would have been outcome determinative had
it been available at trial. For the following reasons, we affirm.
This postconviction proceeding has a long history despite a
preliminary issue with Riley’s 2022 application for the State to conduct
postconviction DNA testing — his implicit concession that no parent sample exists.
The existence of a parent sample of biological material, material containing human
DNA, is a statutory prerequisite to the trial court’s accepting an application for
postconviction DNA testing under R.C. 2953.74(C)(1). Riley’s concession is
dispositive.
In 2016, Riley was indicted on charges of aggravated murder, felony
murder, attempted murder, four counts of felonious assault, discharge of a firearm
on or near prohibited premises, improperly handling a firearm in a motor vehicle,
and having a weapon while under a disability. The charges arose from a drive-by
shooting in which a person wearing unique clothing that enabled witnesses to
identify Riley entered the back seat on the driver’s side of a vehicle, all of which was
recorded on surveillance cameras. The video depicted shots being fired from the
window of the door Riley entered. State v. Riley, 2024-Ohio-5712, ¶ 2, citing State
v. Riley, 2019-Ohio-981, ¶ 3 (8th Dist.). The shots struck and killed Juan Mitchell
and injured another. The trial court sitting as the trier of fact “found Riley not guilty
of aggravated murder because, according to the trial court, the identity of the person
who had fired the gun or guns from the car could not be determined.” Id. at ¶ 2,
citing Riley, 2019-Ohio-981, at ¶ 38. The trial court expressly found Riley complicit in the remaining offenses and sentenced him to an aggregate prison term of 26 years
to life. Id.
As part of his postconviction challenges, Riley filed an application for
DNA testing under R.C. 2953.71 to 2953.81 seeking to retest the shell casings
collected during the investigation of Riley’s crimes. According to Riley’s application,
“[i]n the past, obtaining useful DNA off shell casings was almost always unsuccessful
because the testing standards were not sensitive enough to capture the small
amount of touch DNA present.” Citing a professional article published in 2016, Riley
argued that there could still be touch DNA present on the shell casings, uncollected
by the forensic examiner who collected the original samples from the shell casings.

gun-recovering-dna-bullet-casings (accessed Mar. 31, 2026) [available at
https://perma.cc/JML7-2PWG]. The trial court denied the application, but before
it could issue findings, Riley perfected an appeal. The panel affirmed the denial of
the application after accepting the trial court’s belated findings, concluding that the
DNA testing would not be outcome determinative. Notwithstanding, the Ohio
Supreme Court reversed with three justices claiming it was error for the trial court
to accept the State’s proposed findings, three justices claiming the appellate court
erred by considering the appeal filed before the findings were made by the trial
court, and one justice in favor of dismissing the appeal as improvidently allowed.
See generally Riley, 2024-Ohio-5712. As the Ohio Supreme Court recognized in the earlier appeal of the
postconviction DNA testing application, this matter arises from Riley’s “application
seeking DNA testing of six shell casings discovered at the scene of the shooting.” Id.
at ¶ 4. As noted in the application, however, the lab testing conducted before trial
“detected an ‘insufficient quantity of human DNA’ on the swabs collected from the
outer surface of the casings.” Id. “Riley argued in his application that
‘advancements in DNA testing technology not available’ at the time of his trial made
it possible to test the casings again and yield a result that would exclude him as the
shooter or establish who the shooter was.” Id. In other words, according to Riley,
the State’s forensic examiner could collect a new sample of biological material from
the shell casings for further testing. This request is outside the realm of testing
permitted under R.C. 2953.74(C)(1) when that language is applied as written.
“A court may accept an R.C. 2953.73 application for DNA testing only
if it determines that six conditions apply, [one] of which [is] central to this
appeal. . . . [T]he court must determine that biological material was collected from
the crime scene or the victim and that the parent sample still exists.” State v.
Bonnell, 2018-Ohio-4069, ¶ 19, citing R.C. 2953.74(C)(1). In his application for
DNA testing, Riley claimed it was possible to collect new biological material from
the bullet casings secured during the investigation based on advancements in
forensic collection techniques. As the State argued in the hearing conducted on
remand, in order for the trial court to accept an application for postconviction DNA
testing under R.C. 2953.74(C)(1), however, the court must determine that biological material was both collected from the crime scene (or victim) for the
offense at issue and that parent sample still exists. See Riley, 2024-Ohio-5712, ¶ 12
(“It is axiomatic that there must be some proper biological material to test.”). If no
parent sample exists, the trial court may not accept the application. Bonnell at ¶ 19.
“Parent sample” is defined as “biological material first obtained from
a crime scene or a victim of an offense for which an offender is an eligible offender,
and from which a sample will be presently taken to do a DNA comparison to the
DNA of the subject offender under sections 2953.71 to 2953.81 of the Revised Code.”
The phrase “biological material” expressly means “any product of a human body
containing DNA.” “Biological material may include blood, semen, hair, saliva, and
skin tissue.” State v. Warren, 2022-Ohio-4743, ¶ 13 (2d Dist.), citing R.C.
2933.82(A)(1)(a)(ii). The “collection of a shell casing does not necessarily establish
the collection of biological material.” Id. The collection and retention of a parent
sample of biological material from an item must exist at the time of the application.
R.C. 2953.74(C)(1). Collecting new biological material from tangible objects like
shell casings does not fall under the definition of what constitutes an existing parent
sample of “biological material.”

R.C. 2953.74(C)(1). Collecting new biological material from tangible objects like
shell casings does not fall under the definition of what constitutes an existing parent
sample of “biological material.”
As the Ohio Supreme Court also recognized in an earlier appeal, the
State’s argument has been steadfast: “the swabs collected from the six shell casings
had been consumed during the lab testing and therefore could not be tested again.”
Riley, 2024-Ohio-5712, at ¶ 5. Riley does not contend and, in fact, has never
claimed otherwise, leading the trial court to the conclusion that the original samples of biological material collected no longer existed. As Riley stated in his
application and later clarified in the proceedings following the remand from the
Ohio Supreme Court, he is not seeking a DNA test on a sample taken from the
parent sample currently in existence. Instead, he is requesting the State’s forensic
examiner to generate a new sample of biological material by attempting to collect
additional biological material from the shell casings held in evidence. Tr. 41:20-
42:7. Riley’s request does not adhere to the limitations of R.C. 2953.74(C)(1).
Riley’s argument is based on the tacit concession that no parent
sample exists, and he is expressly seeking the collection of an additional sample of
biological material retrieved from tangible evidence for further testing.1 If such a
request is permitted, it is not through the statutory procedure outlined in R.C.
2953.71 to 2953.81, under which this case proceeded to force the State to conduct
additional DNA testing. See R.C. 2953.84 (“[S]ections 2953.71 to 2953.81 of the
Revised Code . . . are not the exclusive means by which an offender may obtain
postconviction DNA testing, and the provisions of those sections do not limit or
affect any other means by which an offender may obtain postconviction DNA
testing.”).
Riley’s argument primarily focused on the State forensically
obtaining a new sample of biological material from the shell casings and from which
1 The State presented this argument to the trial court at the hearing conducted on
remand from the Ohio Supreme Court. Tr. 44:9-22. further DNA testing could occur.2 He is not requesting the State to test a sample
taken from a parent sample as statutorily defined.3 His claim is limited to advances
in collecting the biological material from shell casings, and as a result of this
distinction, Riley’s application was fatally flawed. Under R.C. 2953.74(C)(1), the
trial court was unable to do anything but reject the application based on Riley’s
argument and the information submitted along with the application. State v.
Marshall, 2025-Ohio-3132, ¶ 11 (1st Dist.) (“If any of the factors listed in R.C.
2953.74(C) are not satisfied, the court is precluded from accepting the
application.”), quoting State v. Emerick, 2007-Ohio-1334, ¶ 15 (2d Dist.), overruled
in part on other grounds by State v. Wilson, 2024-Ohio-4712 (2d Dist.), and R.C.
2953.74(C); see also State v. Williamson, 2018-Ohio-2226, ¶ 10 (8th Dist.)
(concluding no parent sample existed and therefore the trial court did not err in
denying the postconviction application for DNA testing). By seeking the collection
of new biological material from the shell casings, Riley is implicitly conceding that
2 Although the trial court concluded that a parent sample existed in paragraph 20
of the findings of facts and conclusions of law, that conclusion is irrelevant to Riley’s only request, which seeks new testing samples be collected from the shell casings. The trial court’s statements referred to the original samples that contained insufficient biological material for further testing. Riley is not asking for any additional testing of those samples but instead seeks that new samples be preserved from the shell casings directly. 3 It should be noted that the analysis surrounding advances in DNA testing pertains to whether a “definitive DNA test” occurred in the trial proceeding. A “definitive DNA test means a DNA test that clearly establishes that biological material from the perpetrator of the crime was recovered from the crime scene and also clearly establishes whether or not the biological material is that of the eligible offender.” Because there was no “definitive DNA test” in this case, Riley’s discussion regarding R.C. 2953.71(U) is not relevant to the analysis. no parent sample exists for the purposes of R.C. 2953.74(C)(1). If there is relief to
be had, it is not through R.C. 2953.71 to 2953.81 as this case has been presented.
Accordingly, any arguments pertaining to whether the requested
DNA testing would be outcome determinative are moot.4 In light of our conclusion
that no parent sample exists under R.C. 2953.74(C)(1), it cannot be determined that
the trial court erred in concluding that a scientifically sufficient amount of material
does not exist from which a test sample could be extracted under subdivision (C)(2).
The absence of a parent sample necessarily means that there is insufficient material
under (C)(2). The decision of the trial court denying the application for DNA testing
is affirmed.
It is ordered that appellee recover from appellant costs herein taxed.
The court finds there were reasonable grounds for this appeal.
It is ordered that a special mandate issue out of this court directing the
common pleas court to carry this judgment into execution.
4 Even if the issue was not moot, the panel’s conclusion that the postconviction
DNA would not be outcome determinative because Riley was found guilty of complicity and not implicated as the shooter, still holds true. State v. Riley, 2023-Ohio-2588, ¶ 48 (8th Dist.). The Ohio Supreme Court’s decision reversing the panel decision rested on procedural grounds, not as to the merits of that conclusion. See generally Riley, 2024- Ohio-5712. A certified copy of this entry shall constitute the mandate pursuant to Rule
27 of the Rules of Appellate Procedure.
