ABILENE, Texas -

A 23-year-old Abilene man was killed late Sunday in a single-vehicle accident in the 6800 block of US Highway 84 (Winter’s Freeway).

Daniel Tristan, who wasn’t wearing a seat belt, was traveling west in a 2002 Chevrolet Trailblazer when the vehicle entered the grass median and overturned multiple times, ejecting him, Abilene police said in a news release Monday.

Justice of the Peace Mike McAuliffe pronounced him dead at the scene, police said.

"It is not known at this time if alcohol was a factor," Abilene Police Department spokesman George Spindler said in the release.

The investigation continues.
