Troopers with Tennessee Highway Patrol reported Killion's van crossed the center line, and he never hit the brakes before crashing head-on into Arrington's car. Arrington died at the scene.

Officials said Killion's blood alcohol level was .17 percent, twice the legal limit.

Authorities said Killion has four past DUI charges and lost his license 10 years ago. This was Killion's fifth DUI charge and the fifth time he has been charged with driving on revoked license.
