One person is dead and three others injured after a four-vehicle accident in Morgan County. The crash happened on Highway 5 north of Valley Road Friday afternoon. The chain-reaction accident began when a vehicle went over the center line and hit the second vehicle from behind. That sent vehicle 2 into a motorcycle, ejecting the rider as the bike crashed into a fourth vehicle. 51-year old Micheal Benton of Wentsville has been identified as the man riding the Harley Davidson. He was pronounced dead on the scene. 31-year old Andrew Jackson and 13-year old Nathan Jackson, both of Gravois Mills, were in car one. The older Jackson was seriously injured and taken to University Hospital, while Nathan was sent to Lake Regional with moderate injuries. A 54-year old man from Barnett, William Vogt, suffered minor injuries.
