One man is dead and a woman was injured after an all-terrain vehicle crash on Old Alton Road in Madison County. Police said 41 year old Donald W. Enyart Senior of Granite City and 28 year old Shelly Smith of Madison crashed after trying to change lanes on a rural road. Enyart was airlifted to St. Louis University Hospital where he later died.

Smith was also taken to SLU hospital for treatment of minor injuries. Neither rider was wearing a helmet, and authorities speculate that alcohol may have played a role in the accident. The accident took place Wednesday evening near Old Alton Road and Meadowlane Drive in Mitchell, just north of I-270.
