State v. Kochensparger, 2016 Ohio 2870

Jonathon Kochensparger was tried on consolidated indictments for second-degree felonious assault and child endangering (for injuries to a 3‑month‑old), two fifth‑degree heroin possession counts, complicity to possess heroin (fifth degree), and one first‑degree misdemeanor possession count.
On the injury date, Kochensparger was the sole caregiver; the infant was later found lethargic with vomiting and intracranial bleeding; medical experts for the state testified the injuries were non‑accidental, consistent with shaking.
Shelter and jailmates testified about Kochensparger’s state that day (complaining the baby wouldn’t stop crying) and an inculpatory admission to a cellmate; police found heroin residue and paraphernalia in a shelter room and in Kochensparger’s car; he admitted recent heroin use to his parole officer.
Defense presented a medical expert who opined cortical vein thrombosis could explain the injury; state rebutted with another expert excluding that diagnosis.
Trial court granted the state’s pretrial joinder motion; Kochensparger was convicted on all counts after jury verdict and appealed claiming ineffective assistance, manifest‑weight insufficiency, and Confrontation Clause violations for admission of medical records.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Whether defense counsel was ineffective for not renewing a severance objection at close of the state’s case	State: joinder was proper; evidence of each crime simple and direct	Kochensparger: counsel should have renewed severance objection to avoid prejudice from joinder	Not ineffective — renewal would have been futile; appellant failed to show prejudice under Strickland
Whether felonious assault and child endangering convictions are against the manifest weight	State: medical and circumstantial evidence support intentional abuse by defendant	Kochensparger: injuries may be non‑abusive; testimony identifying him as perpetrator unreliable	Affirmed — jury reasonably credited state experts and circumstantial evidence; verdict not against manifest weight
Whether complicity to possess heroin conviction is against the manifest weight	State: evidence showed more than mere presence — shared drug use, paraphernalia, admissions	Kochensparger: mere access/occupation insufficient to prove possession	Affirmed — evidence supported complicity/accomplice liability; not merely presence
Whether admission of medical records violated the Confrontation Clause	State: records were created for treatment (primary purpose), thus non‑testimonial	Kochensparger: records were created to build a prosecution and thus testimonial	Affirmed — records served treatment purposes and were non‑testimonial under the primary‑purpose test (Crawford/Bryant/Maxwell)
