Ohio Ct. App.2023Background
- Seven‑month‑old J.F. was found unresponsive after an overnight stay with defendant Joshua Mounts; hospital treatment revealed a right parietal skull fracture and left subdural bleed. Hospital clinicians reported recent traumatic injury and suspected abuse.
- Mounts was charged with aggravated murder and felony murder; jury acquitted on aggravated murder but convicted on felony murder; sentence 15 years to life.
- State experts (including Drs. Makoroff and Dean) testified the skull fracture and fresh blood at the fracture site showed recent blunt‑force trauma; Dr. Dean’s autopsy/histology showed no healing.
- Defense experts (Drs. Wiens, Chundru, Guajardo) testified the injuries showed healing and were older; dispute arose over original histology slides vs. recut slides.
- Trial court excluded portions of defense expert testimony about original histology slides under Crim.R.16(K) after defense counsel acquiesced; lay witnesses described Mounts’s distant demeanor and behavior at the scene.
- On appeal Mounts raised four claims: manifest‑weight of the evidence, improper limitation on defense experts, improper use of a lay witness as an expert, and prosecutorial misconduct in rebuttal closing.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether conviction is against the manifest weight of the evidence | State: jury could credit hospital and coroner experts and lay witnesses showing recent trauma and suspicious caregiver conduct | Mounts: evidence was conjectural; defense experts showed injuries were older and not recent | Court: Deferral to jury credibility determinations; evidence did not weigh heavily against conviction — no miscarriage of justice; assignment overruled |
| Whether trial court erred by prohibiting defense experts from testifying beyond their written reports (Crim.R.16(K)) | State: rule requires timely expert reports; exclusion proper for undisclosed opinions | Mounts: trial court improperly limited Wiens/Guajardo and allowed state experts freer scope | Held: Mounts waived complaint by acquiescing at trial and abandoned undeveloped claims; no preserved error |
| Whether lay witness Casteel was presented as an expert and improperly opined that Mounts’s behavior showed guilt (Evid.R.701) | State: Casteel was a lay witness with EMS experience; his demeanor observations were perception‑based and helpful | Mounts: Casteel was effectively treated as an expert and improperly testified that behavior indicated guilt | Held: No abuse of discretion — Casteel not held out as an expert; lay opinion admissible under Evid.R.701 and jury could weigh it |
| Whether prosecutor’s rebuttal comments amounted to prosecutorial misconduct | State: comments addressed expert bias, credibility, and weight; fair argument on motivations and credibility | Mounts: prosecutor disparaged defense experts, vouched for state witnesses, and improperly referenced uncalled state experts | Held: Only one remark was objected to and it was proper (bias/pecuniary interest). Remaining remarks reviewed for plain error; although some comments (e.g., referencing additional uncalled state experts) were improper, Mounts failed to show plain error that affected the outcome — no reversal |
