ABERDEEN, S.D. (AP) – A man who pointed an unloaded shotgun at a South Dakota Highway Patrol trooper has been sentenced to serve 10 years in prison. Forty-six-year-old Randall Jungwirth, of Athol, earlier had pleaded guilty to aggravated assault of a law officer. In exchange for his guilty plea, prosecutors dropped a felony drunken driving charge. Jungwirth must serve at least half of his sentence before being eligible for parole. Authorities say Jungwirth pulled a shotgun on a trooper who was trying to administer a field sobriety test last Nov. 6 and squeezed the trigger twice before fleeing when the officer took cover behind his vehicle. Jungwirth was found hiding in an abandoned mobile home near Ashton the next day.
