State v. Carroll, 2016 Ohio 374

In Nov. 2013 Carroll parked at a Best Western, opened his trunk, and was seen on hotel surveillance reaching into the gravel landscaping behind his car; hotel clerk observed disturbed gravel afterward.
Police recovered a pill bottle under the disturbed gravel containing 56 individually wrapped baggies of an off‑white substance; total weight of the substance was 21.31 grams.
BCI forensic scientist tested 21 of the 56 units using hypergeometric (random) sampling; all 21 tested positive for cocaine, yielding a 95% confidence that ≥90% of units were cocaine.
Carroll’s lone witness (his girlfriend) testified they had been smoking marijuana, saw another man in the area, and that Carroll checked the area and trunk; the jury found her testimony not credible.
A jury convicted Carroll of possession of cocaine in an amount ≥20 g but <27 g (second‑degree felony); the trial court imposed a mandatory five‑year prison term.
On appeal Carroll argued (1) insufficient evidence/manifest weight error as to possession and (2) insufficient proof of the quantity because not all units were tested; the Fourth District affirmed.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Whether evidence sufficed to prove Carroll knowingly possessed cocaine	State: surveillance, clerk and officer testimony, disturbed gravel, and discovery of the bottle at the spot inferred Carroll placed the bottle; supports constructive/actual possession	Carroll: defense testimony denied knowledge; argued the State failed to prove he knowingly possessed the drugs	Court: Evidence (video + corroborating witness/officer testimony) permitted reasonable inference of possession; verdict not against manifest weight or insufficient
Whether hypergeometric/random sampling supported finding of ≥20 g of cocaine	State: expert’s hypergeometric sampling and conclusion that the multi‑unit, similarly packaged sample was cocaine justified attributing the total weight to cocaine	Carroll: expert admitted 100% certainty would require testing all units and did not weigh tested units; argued State should have tested every bag to prove quantity	Court: Accepted hypergeometric/random sampling as legally sufficient; expert’s 95% confidence that ≥90% of 56 units were cocaine supported conviction for ≥20 g and <27 g
