People of Michigan v. Kellie Nichole Stock

Summary

The Michigan Supreme Court reversed the portion of the Court of Appeals judgment upholding the defendant's convictions for operating while intoxicated causing death and causing serious impairment. It held that an unidentified cocaine metabolite in the defendant's urine, without evidence identifying the metabolite or showing that it was itself a controlled substance, did not sufficiently prove that cocaine was in her body when the crash occurred. The court remanded for further proceedings, including consideration of whether resentencing on the remaining convictions was required.
