The Colorado State Patrol is investigating a rollover crash that killed a man Friday night.

The crash happened on Colorado Highway 78 in Pueblo County, about nine miles east of Beulah.

Troopers say a 29-year-old man from Divide crashed into a guardrail when he failed to negotiate a curve. The car rolled several times and the driver was thrown from the car.

Troopers say he wasn't wearing a seat belt at the time of the crash.
