A single-vehicle crash Saturday night on La. 347 near Delcambre Road killed two St. Martinville residents, State Police spokesman said Sunday.

At 10:22 p.m., Danny Boudreaux, 45, was traveling south on La. 347 in his 1997 Chevrolet Corvette when he ran off the road to the left in an area of the road with a slight left curve, said Trooper 1st Class Stephen Hammons of Troop I.

The car hit a ditch, overturned several times and struck a tree, Hammons said in a news release.

Boudreaux was not wearing a seat belt and was ejected from the car, but his passenger, Tammy Boudreaux, 44, was wearing a seat belt, Hammons said.

The St. Martin Parish Coroner’s Office pronounced both people dead at the scene, Hammons said.

Troopers are unsure if impairment played a role in the accident and submitted a toxicology sample to the State Police Crime Lab in Baton Rouge for analysis, Hammons said.
