The court of appeals decided State v. Shelton, ___ N.C. App. ___ (2019) yesterday, determining that the evidence of the defendant’s impairment was sufficient when he took impairing drugs hours before crashing his vehicle into a pedestrian after his brakes failed. Two aspects of the case are of particular interest: (1) the court’s evaluation of the sufficiency of the evidence in a case where no one opined that the defendant was impaired; and (2) how the State obtained evidence that drugs remained in the defendant’s system in the first place.
