ST. MARY PARISH -- Late Tuesday night, Troopers with Louisiana State Police Troop I investigated a single-vehicle crash on La. 182 at Sun Road, which killed two men.

According to investigating troopers, at 11:44 p.m., 25-year-old Bryan Mitchell of Houma was driving a 1994 GMC SUV west on La. 182.

For unknown reasons Mitchell drove off the right side of the road, entered a ditch, his vehicle overturned and struck a utility pole.

Mitchell, who was restrained, and 40-year-old Tyronne Gray of Thibodeaux, who was unrestrained, were pronounced dead at the scene by the St. Mary Parish coroner.

A third occupant in the vehicle, 33-year-old Anna Collette of Franklin, sustained moderate injuries and was transported to the hospital. Troopers are still working to determine if she was restrained.
