MIDLAND A 24-year-old security guard from Midland was killed early Wednesday after his truck rolled over on State Highway 191 just west of Midland, Department of Public Safety communications operator Gilbert Villarreal said.

Scott Mark Wanamaker, a security guard with the Transportation Security Administration, was pronounced dead at the scene of the crash when his eastbound 2003 Ford Ranger rolled into the shoulder at 1:40 a.m. Wednesday.

According to a report Villarreal read from DPS Trooper Beau Martinez, Wanamaker began drifting into the center lane west of State Highway 158. He overcorrected and began rolling.

Wanamaker was not wearing a seatbelt, Villarreal said. The report did not state whether Wanamaker's body remained in Ford.
