State v. Wright
2017 Ohio 9041
Oh. Ct. App. 4th Dist. Lawrenc...2017Background
- Defendant John F. Wright was convicted by a jury of three drug offenses based on a controlled buy and pills seized from him; he was sentenced to a combined ten-year term.
- Evidence included a prescription bottle with 98 pills marked "A214" and a bag of 95 pills consisting of several markings (M30, A215, 224, K8, A214).
- BCI forensic scientist Stanton Wheasler chemically tested six pills total — one from each differently marked group — and each tested positive for oxycodone; his lab report referenced hypergeometric sampling but he did not apply that method in this case.
- Wheasler testified he could only state within a reasonable degree of scientific certainty that the six tested pills were oxycodone; he explicitly testified he did not test a sufficient sample from larger groupings (e.g., would need ~20 of 63 M30 pills) to infer reliably about the remainder.
- Wright moved to exclude the untested pills and for acquittal (Crim.R. 29) arguing the state proved at most 135–180 mg oxycodone from tested pills, below statutory bulk thresholds; the trial court denied exclusion and the Rule 29 motion, leaving the sampling/weight question for the jury.
- The appellate court held the trial court erred: because the expert did not use an acceptable random/hypergeometric sampling method and could not opine, with a reasonable degree of scientific certainty, about the untested pills, the untested pills lacked the required scientific foundation and should have been excluded; conviction reversed and case remanded for new trial.
Issues
| Issue | Plaintiff's Argument (Wright) | Defendant's Argument (State) | Held |
|---|---|---|---|
| Admissibility of untested pills | Remaining untested pills lacked foundation because expert did not test a statistically sufficient sample to opine as to the whole population | Expert is accredited, followed lab protocol (one-per-marking), and jury should weigh reliability | Court held trial court erred; untested pills should have been excluded because expert could not opine with reasonable scientific certainty about them |
| Timing of exclusion motion | Motion was timely once expert testified about sampling limitations | Question of weight and credibility for jury; no basis to exclude after report/testimony in evidence | Court found motion timely under Evid.R. 103 and trial court misapplied law by refusing to consider sampling testimony |
| Use of hypergeometric/random sampling method | Where expert did not employ accepted random sampling, inference to population is unreliable | Sampling protocol defended as standard practice; jury may accept or reject | Court accepted that hypergeometric sampling is acceptable generally, but because it was not used here, the inference was unsupported and pills beyond the six tested were inadmissible |
| Double jeopardy/retrial bar | (Implicit) Excluding evidence could require acquittal; retrial might be barred | State argued retrial allowed | Court held error was trial error; retrial is not barred (Double Jeopardy does not preclude retrial for evidentiary trial errors) |
