Hit-skip wrecks create challenges for investigators who piece cases together

Lt. Christopher Kinn, a reconstructionist with the Ohio State Highway Patrol, talks about his work piecing together the details surrounding hit skip crashes at the State Patrol headquarters on West Broad Street in Columbus. The troopers in Knox County arrived at the crash scene, the one where someone had hit and killed a motorcyclist but didn't stop, and found a crucial piece of evidence the fleeing vehicle had left behind: a running board.
