The Kansas Highway Patrol reported in a media release that just before 7 p.m. on Sunday a trooper performed a traffic stop on a Ford Windstar minivan with Oklahoma tags on US 40 highway, in front of Mittens Truck Stop at Oakley, for speedway.

While being placed under arrest for a felony warrant, the driver, Bryce Castell, 20, of Oklahoma City produced a firearm from his waistband.

Castell turned the gun on himself and died from the self-inflicted injury at the scene.
