SAC CITY, Iowa (AP) — An Iowa man has pleaded not guilty to providing alcohol to a teenager before a fatal car crash in August. Twenty-one-year-old Matthias Stork, of Breda, entered his written plea Wednesday in Sac County District Court on two counts of selling, giving or supplying alcohol to a minor resulting in death. The Sioux City Journal reports his trial is scheduled to begin in March.

Stork is accused of supplying beer to a 17-year-old in August who later drove a vehicle. The teen’s car crashed into a vehicle driven by 16-year-old Bailey Jacobsen. She and her passenger, 16-year-old Lindsey Quirk, both of Wall Lake, were killed.

The teen driver has pleaded not guilty to vehicular homicide. Authorities say his blood alcohol level was above the legal limit for driving.
