The New Orleans Police Department officer who shot and killed a man Saturday morning in the Lower 9th Ward was identified Sunday as Detective Timothy Bender.

NOPD spokesman Tyler Gamble did not identify the dead man but said he was 60.

Police said Saturday that Bender, who was in the neighborhood on an unrelated investigation, was flagged down near Caffin Avenue and Chartres Street about 9:30 a.m. by someone who said a man had been driving erratically down the street. The detective caught up with the man and a physical altercation followed, Gamble said.

The situation escalated to the point where Bender shot the man, who died at the scene about 10:15 a.m. Bender was not injured.

Police Superintendent Michael Harrison said the officer was defending himself and felt he had to draw his weapon and fire.

The man who was killed lived about a block away from the shooting and had been involved in an argument with his wife preceding the incident. He left his house and got in his pickup, crashing through a wooden fence as he exited the driveway. He hit a parked car across the street, drove away and hit at least one more parked car before his truck came to a rest in a driveway about a block away.

Neighbors said the man also hit several houses.

What led to the altercation with the officer is under investigation, Gamble said.

Authorities also are investigating whether the man who was killed had a weapon. Gamble said no gun was recovered at the scene.
