Original story:

A woman is dead after crashing in Marrero with a Jefferson Parish Sheriff's Office deputy on Monday, the agency said.

The fatal wreck happened at the corner of Barataria Boulevard and Mount Rushmore Drive at 9:21 a.m., the Sheriff's Office said.

The name of the victim was not immediately available.

Louis Mitchell, who lives nearby on Mount McKinley Street, was getting ready to walk his dog when he heard the crash. He rushed to the scene and he and another man helped the deputy out of the cruiser and to the side of the road.

Mitchell said the deputy, who was heading west on Barataria Boulevard, had an abrasion on his arm and right leg. He said the deputy expressed disbelief that the woman had pulled into the intersection as he sped through it. The woman was turning east from Mount Rushmore on to Barataria.

“He was dazed,” he said. “He was shook up so bad. He said, ‘I don’t understand how she could pull out like that.’”

Mitchell then ran to the other vehicle and what he saw sent chills up his arm. The driver’s side window was shattered and he saw the woman, who he estimated was in her 70s, gasp for her last breaths.

“She was in bad condition,” he said. “I couldn’t stand to look at it too much — I had to get away from it.”

“I knew at that moment she was dead,” he added.

Michael Rodriguez said Mount Rushmore Drive, where he lives, is one of three streets in a row that need traffic lights.

"They need to put a light here, College and Pritchett," he said.
