Released by the Texas Department of Public Safety:
A DPS Highway Patrol corporal was killed in an on-duty traffic crash Monday night in Montague County.
Corporal David Ralph Slaton, 56, was killed in a two-vehicle wreck two miles south of Ringgold. The Montague County Sheriff's Office received a 911 call reporting the crash at 10:42 pm.
Cpl. Slaton, who was stationed in Bowie, was driving his patrol car northbound on US 81. Brett Douglas Noga, 37, from Morrison, Okla., was driving a 2007 Peterbuilt truck-tractor-semitrailer southbound on 81. Investigators believe that Cpl. Slaton struck a cow in his lane, and the impact of the collision caused his vehicle to go into the southbound lane. The two vehicles struck head-on in the southbound lane.
Brett Douglas Noga, the driver of the truck-tractor-semitrailer, was not injured and was not transported to a medical facility. Cpl. Slaton's body was taken to the Southwestern Institute of Forensic Sciences in Dallas.
The Texas Highway Patrol Crash Investigation Team will conduct an investigation of the wreck.
