A single-vehicle accident in eastern Iowa’s Marion County has claimed the life of a man from southwest Iowa. The Iowa State Patrol reports 47-year old Jason Cameron Willey, of Clarinda, died when the 2011 Chevy Camaro he was a passenger in, missed a curve and ran off the road before impacting a ditch and rolling several times. Willey was ejected as the car rolled, and died at the scene. He was not wearing a seat belt. The driver, 24-year old Jalen Zachary Frost, of Corydon, was injured and flown by helicopter to Mercy Hospital.  Authorities say Frost was buckled-up at the time of the accident, which happened at around 6:10-p.m. Monday on Highway T-15 southbound, near the intersection of Highway S-71.
