Case Facts & Court Holding

Key Facts & Case Background

Kenneth Yarborough drove his van into a parked station wagon at a pre-existing accident scene on an interstate highway, killing a four-year-old child. Witnesses testified Yarborough appeared intoxicated, and police found alcohol in his van. He was charged with homicide by vehicle, which requires proof of reckless driving, but was acquitted. However, based on Yarborough’s admission that he did not “attend to everything” while driving, the jury was instructed on involuntary manslaughter with the predicate “unlawful act” being the misdemeanor of careless driving. The jury convicted him of this fourth-degree felony. The careless driving statute, NMSA 1978, § 66-8-114(B), requires only a showing of ordinary negligence (operating a vehicle in a “careless, inattentive or imprudent manner”). Yarborough appealed, arguing that a felony conviction cannot be based on a showing of mere civil negligence.
