A Breaux Bridge man died Friday morning after the vehicle he was in drove off a highway and crashed into a tree, according to State Police.

He was not wearing a seat belt, Master Trooper Brooks David said in a news release.

State Police were called shortly before 11:55 a.m. to La. 96 near Zeb Drive west of Catahoula, where the 2007 Toyota Tundra driven by Joseph Charles, 49, of Breaux Bridge, had been traveling east on LA 96 and, for unknown reasons, traveled off the left side of the roadway and struck a tree, David said.

Charles, who was wearing a seat belt, was transported to a local hospital and treated for moderate injuries.

The front seat passenger, Christopher Alexander, 31, was not wearing a seat belt and suffered fatal injuries, David said. Alexander was pronounced dead on scene by the St. Martin Parish Coroner’s Office.

Shawn Dural, 37, also of Breaux Bridge, a rear seat passenger, was wearing a seat belt and sustained moderate injuries. Dural was transported to a local hospital for treatment, David said.

It is unknown if impairment is a factor in the crash. A standard toxicology sample was obtained from Charles and submitted to the Louisiana State Police Crime Lab for analysis. The crash remains under investigation and charges are pending.
