In re A.S., 2019 Ohio 2359

A pizza-delivery driver was assaulted and robbed after being lured to a Price Hill residence; the victim could not identify the attackers.
Police traced the pizza order to juvenile M.B.; M.B. identified “Black Tino,” later shown to be A.S., and implicated A.S. in the robbery.
Fingerprint matches from the victim’s vehicle linked prints in a database to A.S.; magistrate relied on that evidence and recommended adjudication.
A.S. objected, contesting fingerprint authentication and arguing the evidence failed to prove his guilt beyond a reasonable doubt.
The juvenile court excluded the fingerprint evidence on independent review but credited M.B.’s identification and testimony that A.S. punched the victim, adjudging A.S. delinquent.
This appeal challenges (1) manifest weight of the evidence and (2) whether the juvenile court improperly disregarded the magistrate’s credibility findings under Juv.R. 40.

Issue	Plaintiff's Argument (State)	Defendant's Argument (A.S.)	Held
Was adjudication against the manifest weight of the evidence?	M.B.’s in-court ID and testimony, corroborated by police investigation, support adjudication.	M.B.’s testimony was inconsistent and incredible; fingerprint evidence was excluded, leaving unreliable testimony.	Adjudication not against the manifest weight; court found M.B.’s testimony credible as to A.S.
Did the juvenile court violate Juv.R. 40 by failing to defer to magistrate’s credibility findings?	Court may undertake independent review of objected matters and weigh credibility de novo.	Juvenile court improperly overruled magistrate’s credibility assessment without new evidence.	No violation; juvenile court properly performed independent review under Juv.R. 40(D)(4).
