ABERDEEN, S.D. (AP) — An Aberdeen man has been sentenced to 15 years in prison with five years suspended in a crash that killed a man just weeks away from getting married. Nineteen-year-old Carson Maunu earlier pleaded guilty to vehicular homicide in an agreement with prosecutors. Maunu originally faced three felonies. Maunu was driving a pickup truck last June that crossed the center line on an avenue in Aberdeen, and collided with a motorcycle, killing 27-year-old Casey Kulm, of Groton. Brown County State’s Attorney Ernest Thompson said Maunu had been drinking alcohol that night and left the scene of the crash. Thompson argued for a 15-year sentence.
