A 25-year-old Houma man was killed in a single-vehicle crash Monday afternoon on La. 3134 in Jefferson Parish, State Police said.

Edgard Santos Gonzales of Houma was driving a 2002 Nissan Pathfinder north on La. 3134 at La. 45 shortly before 4:30 p.m. when he lost control and drove into a drainage ditch, State Police said. The vehicle rolled over and came to rest on its roof, partially submerged in water.

A passing motorist pulled the Pathfinder out of the ditch, but it was empty. A search of the area found Gonzales submerged in the water.

Gonzales, who was not wearing a seat belt, was pronounced dead at the scene. He was the only occupant of the vehicle.

State Police said whether Gonzales was impaired is unknown; routine toxicology test results are pending.

It was raining heavily at the time of the crash.
