State v. Boaston (Slip Opinion)
153 N.E.3d 44
Ohio2020Background
- Ronald Boaston was convicted of murder for the strangulation death of his ex‑wife, Brandi Gonyer‑Boaston; he was sentenced to 15 years to life.
- The prosecution produced Dr. Scala‑Barnett’s autopsy report more than a year before trial, but the report did not state two opinions later elicited at trial: (1) time of death based on stomach contents ("within 1–2 hours" after a breakfast sandwich) and (2) that a rectangular abrasion under the victim’s chin was consistent with the buckle on a glove recovered from Boaston.
- Defense counsel met the coroner 19 days before trial and learned these opinions orally; the state declined to supplement the written report. The trial court allowed the coroner to testify to those opinions despite defense objections under Crim.R. 16(K).
- Key non‑expert evidence: evidence of Boaston’s stalking/jealousy (spyware, harassing calls/texts), threatening statements, suspicious actions (ATM withdrawals, fueling the victim’s car), cell‑tower records placing the victim far from home after she left, DNA on the victim’s clothing that included a Boaston‑male profile, and the victim’s body found partially wrapped in plastic in Fulton County.
- The Ohio Supreme Court held admission of expert opinion not disclosed in a Crim.R. 16(K) written report is error but found the error harmless here because the remaining evidence overwhelmingly supported guilt beyond a reasonable doubt.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether expert opinion testimony not set out in a Crim.R. 16(K) written report must be excluded | State: Crim.R. 16(K) requires a written summary but does not demand detailed "scientific reasoning;" trial court has discretion and noncompliance does not always require exclusion | Boaston: Opinions not in the written report violated Crim.R. 16(K) and must be excluded (prejudice and unfair surprise) | Error to admit expert opinion that was not disclosed in a Crim.R. 16(K) written report. |
| Whether the trial court’s discretion or waiver doctrines defeated the Crim.R.16(K) objection | State: Court can regulate discovery under Crim.R. 16(L) and defense conduct (meeting with coroner) shows no surprise/waiver | Boaston: He had no duty to force prosecution to supplement; rule’s remedy (preclusion) is mandatory | Crim.R. 16(K) is unambiguous and its exclusionary remedy is mandatory; waiver argument rejected. |
| What harmless‑error standard applies and whether error was prejudicial | State: Even if error, apply Crim.R. 52 and Morris/Harris harmless‑error framework; error did not affect substantial rights | Boaston: The excluded opinions were critical links and their admission prejudiced his defense | Apply Morris/Harris three‑part harmless‑error test; here the error was harmless because the remaining evidence established guilt beyond a reasonable doubt. |
| Whether, after excising the improperly admitted expert opinions, the remaining evidence supports the conviction | State: Remaining circumstantial evidence (jealousy/stalking, cell data, physical evidence, behavior) overwhelmingly proves guilt | Boaston: The coroner’s time‑of‑death and glove‑buckle opinions were the decisive links; without them the case is weak | Court: After removing the coroner’s opinion evidence, the remaining evidence still established guilt beyond a reasonable doubt. |
