The Jefferson Parish Sheriff’s Office is investigating a possible murder and attempted suicide on Jutland Drive in Marrero, where firemen burst through the back door of a burning house shortly after 1 p.m. Monday to find a dead woman on the floor and a man lying on top of a knife in a nearby hallway.

The man, who was badly burned, was still alive and was taken to the hospital for treatment of his burns and slash wounds to his neck, JPSO spokesman Col. John Fortunato said.

The woman had what appeared to be several stab wounds to her chest and was pronounced dead at the scene.

Deputies have not identified the dead woman or the man who was taken to the hospital.

A billow of black smoke from the fire at 1705 Jutland was spotted by neighbors and people at the nearby John Ehret High School, where JPSO intervention officer Eric Lentz was stationed.

He was among the first on the scene, along with traffic enforcement officer Jerry Bonds.

Firefighters with the Marrero-Harvey Volunteer Fire Department No. 1 knocked down the back door and soon saw the burned and wounded body of the woman on the floor.

After spotting the man, they rolled him over and saw the knife, Fortunato said.

The man was taken first to West Jefferson Medical Center then transferred to Interim LSU Hospital.

David Alexander, who owns the house next door to 1705 Jutland, said he was friendly with the woman who lived there but didn’t know her very well.

“It’s just a sad thing,” he said.

Another neighbor, John McCall, said he called 911 at 1:20 p.m. when he saw the smoke and then helped a deputy get through a back gate with an ax that he had.

He said the smoke was too thick to get into the house until firefighters arrived.
