Tire tracks are visible on the side of the highway on Monday, Sept. 14, 2020 where Joe Boever’s truck sat Saturday night when he was killed while walking back to the vehicle outside of Highmore, S.D. For South Dakota Attorney General Jason Ravnsborg spending Saturday driving hundreds of miles on the state’s roads was not unusual. But by Sunday, it was clear that his latest trip was anything but routine — an investigation was underway that would later reveal he struck and killed a man walking along a rural stretch of highway.
