NORMAN, Okla. (AP) — Investigators have identified the three storm chasers killed in a two-vehicle crash at a rural West Texas intersection.

Sgt. John Gonzalez of the Texas Department of Public Safety identified the storm chasers as 57-year-old Kelley Gene Williamson and 55-year-old Randall Delane Yarnall, both of Cassville, Missouri, and 25-year-old Corbin Lee Jaeger of Peoria, Arizona.

Gonzalez said a Chevrolet Suburban driven by Williamson ran a stop sign at the intersection and slammed into the Jeep driven by Yarnall with Jaeger as a passenger. Gonzalez said Yarnall and Jaeger were wearing seatbelts but Williamson was not.

The three were all killed instantly.
