Cpl. David Ralph Slaton, 56, was northbound on U.S. Highway 81 about 10:45 p.m. when he struck a cow that had wandered onto the road east of Wichita Falls along the Oklahoma border.

The impact pushed his vehicle into the northbound lanes, where he hit a southbound semi, said Tela Mange, a spokeswoman for the Texas Department of Public Safety.

Slaton died at the scene. The truck driver, 37-year-old Brett Douglas Noga of Oklahoma, was not injured.

Slaton joined DPS in 1974 and was stationed in Bowie for his entire career.
