Three storm chasers were killed Tuesday in a crash east of Lubbock, according to KLBK.

It happened just before 3:30 p.m. in the town of Spur. The area was under a tornado warning at the time.

The victims were reportedly chasing the storm when they crashed into another vehicle. A black suburban driving north on FM 1081 went through a stop sign and collided with a black jeep that was heading westbound on FM 2794 around 3:30 p.m. Tuesday, DPS Sgt. John Gonzalez confirmed.

DPS officials identified Kelley Gene Williamson, 57, of Cassville, Mo., as the driver and Randall Delane Yarnall, 55, also of Cassville, Mo., as the passenger in the suburban. They say Williamson was not wearing a seatbelt at the time of the crash.

The victim in the Jeep has been identified as Corbin Lee Jaeger, 25, of Peoria, Ariz.

The Texas Department of Public Safety and the Dickens County Sheriff’s Department are investigating.
