Baton Rouge police are investigating the fatal shooting Thursday of a North 31st Street man who died in his backyard — about six weeks after an unrelated shooting death in the same neighborhood.

“I’m so tired of this,” said East Baton Rouge Parish Metro Councilwoman C. Denise Marcelle, who arrived at the scene in her district to comfort the family.

Darius Johnson, of 2746 N. 31st St., was shot and killed at about 4:15 p.m., and Emergency Medical Services officials said he was pronounced dead at the scene.

Johnson, 23, was found in the backyard of his residence, behind a row of houses along a treeline near basketball courts at a neighborhood park.

Neighbors said he was running from the park when he was shot.

Marcelle said Johnson was about to graduate from a technical school.

Visibly shaken, Marcelle said, “This is a senseless murder.”

Just a month and a half ago, a dispute over a young woman’s driving on Iroquois Street, a block from Thursday’s shooting, apparently sparked a street brawl between two families that ended with her stepfather shot dead. Walter Houston, 33, died on the way to a hospital Sept. 15 after being shot in the chest that evening.

“We’ve had enough,” said East Baton Rouge Parish District Attorney Hillar Moore, who also was at the scene of Thursday’s fatal shooting and who makes it a point to visit murder scene investigations.

Cpl. Don Coppola Jr., a Baton Rouge Police spokesman, said there are no known suspects or motives at this time in the Johnson slaying.

Police asked that anyone with information about the shooting contact the Violent Crimes Unit at (225) 389-4869 or Crime Stoppers at (225) 344-7867.
