A fifth person has died of injuries suffered in a head-on collision Friday in Acadia Parish, State Police said on Saturday.

Joshua Lejeune, 24, Port Barre, died at a local hospital, Trooper 1st Class Stephen Hammons said.

Also Saturday, State Police identified two other people who died in the wreck as a mother and son. They are Laura Bartram, 44, and her 23-year-old son, Justin, both of Opelousas, Hammons said in a news release.

The Bartrams and Lejeune were in a 2005 Honda Civic driven by Jacob Courville, 22, of Eunice, when the wreck happened about 2:30 p.m. Friday, just south of Eunice, State Police have said.

The Honda was headed north on La. 13 when it crossed the highway’s center line for reasons that are still under investigation.

It collided with a southbound 2002 Chevrolet Tahoe, State Police said.

Courville was wearing a seat belt, but Lejeune and the Bartrams were not.

A passenger in the Chevrolet who was not wearing a seat belt, Jamie Prejean, 29, of Mamou, was pronounced dead at the scene, Hammons has said.

The sole survivor of the wreck, the driver of the Chevrolet, 48-year-old Chaman Richardson, also of Mamou, was taken to a hospital with moderate injuries. He was wearing a seat belt.

Troopers do not know if impairment was a factor in the crash, but routine toxicology samples were collected and submitted to the State Police Crime Lab for analysis.
