ABERDEEN, S.D. (AP) – A man who pointed an unloaded shotgun at a South Dakota Highway Patrol trooper has pleaded guilty to an aggravated assault charge. Authorities accused Randall Jungwirth of pulling the shotgun on a trooper who was checking on Jungwirth’s stopped vehicle on a Spink County road last November, and pulling the trigger twice before fleeing on foot. Jungwirth was found the following day hiding in an abandoned mobile home near Ashton. Jungwirth faces up to 25 years in prison when he is sentenced June 11 on the charge of aggravated assault of a law enforcer. In exchange for his guilty plea, prosecutors dropped a felony drunken driving charge.
