A Cheyenne man is dead following a rollover accident just north of Chugwater Sunday morning.

The Wyoming Highway Patrol says 21-year-old Vincent Paustian was headed south on I-25 around 10:00 a.m., when he lost control of his car and rolled it multiple times.

Paustian, who was not wearing his seat belt, was thrown from the car and died on scene.

Excessive speeding may have contributed to the crash which marks the 19th highway death in the state this year.  There were 48 fatalities during this same period last year.
