MARRERO — A man driving a tractor following a Friday night Carnival parade was on life support after being hit by an intoxicated driver early Saturday morning, according to the Jefferson Parish Sheriff’s Office.

About 2:50 a.m., 52-year-old Marrero resident Don Dauzat was operating a John Deere tractor as part of a group of tractors being repositioned following Friday night’s east bank parades, said Sheriff’s Office spokesman Glen T. Boyd.

Dauzat was crossing Lapalco Boulevard at Paxton Street on a green light when he was hit by a 2002 Ford Explorer driven by 54-year-old Gretna resident Michael Burrie, Boyd said. Burrie had disregarded a red light, Boyd said.

The tractor rolled over and Dauzat was ejected onto the road.

Dauzat, who suffered severe head trauma, was on life support in critical condition at Interim LSU Hospital as of Saturday afternoon, Boyd said.

Burrie was taken to West Jefferson Medical Center with minor injuries. He was booked on counts of driving while intoxicated, reckless operation and vehicular negligent injury.

If Dauzat dies, the charges will be upgraded to include vehicular homicide, Boyd said.
