State v. Thorn, 2018 Ohio 1028

Jason Thorn attempted a fraudulent return at Walmart: he picked up three routers, handed them to customer service for store credit on a gift card, and was detained by store security before receiving any gift card. Deputies arrested him for theft and, incident to arrest, found heroin on him.
Thorn was incarcerated in Pennsylvania on a parole violation and did not attend multiple preliminary hearings in Belmont County; he submitted a February 23, 2015 inmate request to Pennsylvania authorities referencing the Interstate Agreement on Detainers (IAD).
Thorn filed multiple pro se IAD/speedy-trial motions in Belmont County (Sept. 2, 2015 and March 7, 2016); the trial court denied them, concluding he never filed the required IAD demand/certificate and later waived IAD rights by letter.
Thorn was tried by jury and convicted of fifth-degree felony possession of drugs and first-degree misdemeanor theft; he moved for acquittal (Crim.R. 29) on the theft count at trial, which was denied.
At sentencing the court credited Thorn with seven days in jail (recognizance bond otherwise issued) despite Thorn’s claim he served 215 days in Belmont County; court concluded most detention was under Pennsylvania custody via the IAD and double-credit would result.
Thorn appealed raising three assignments of error: (1) IAD/speedy-trial violation and dismissal, (2) entitlement to 215 days jail credit, (3) insufficiency of evidence for theft conviction.

Issue	Plaintiff's Argument (State)	Defendant's Argument (Thorn)	Held
Whether Thorn substantially complied with the IAD such that the 180-day speedy-trial period ran and dismissal was required	State: Thorn did not file the required written demand/certificate under Article III, so IAD did not trigger	Thorn: He substantially complied (inmate request to superintendent) and the 180-day clock ran; dismissal required	Court: Thorn failed to file the formal demand/certificate; did not substantially comply; denial of dismissal affirmed
Whether Thorn is entitled to 215 days jail-time credit against his Ohio sentences	State: Most time in Ohio custody was actually under Pennsylvania custody via IAD/parole detainer; credit limited	Thorn: Trial court promised credit and he relied on it; entitlement to full 215 days (promissory estoppel)	Court: Credit limited to seven days; promissory estoppel inapplicable against state and double-credit would occur if full credit awarded; affirmed
Whether evidence was insufficient to convict Thorn of theft because he never obtained or exerted control over the gift card	State: Thorn engaged in a fraudulent return scheme and thus knowingly sought to obtain the gift card even if he never physically possessed it	Thorn: He never obtained or exerted control over anything of value; trial court should have granted acquittal	Court: Conduct initiating fraudulent return constituted obtaining/exerting control for theft purposes; sufficiency of evidence supports conviction; affirmed
