A St. Bernard Parish Sheriff’s Office deputy shot and killed a man after a confrontation Tuesday afternoon in Chalmette that briefly sent a deputy to the hospital, State Police said.

Authorities released few details about the incident, which occurred near the intersection of East St. Bernard Highway and Volpe Drive about 2 p.m.

State Trooper Evan Harrell said the dead man wielded a weapon of some sort during an “altercation” with a deputy.

Harrell said the deputy was injured while calling for backup from two other deputies, who arrived before the shooting. Harrell said he did not know why the deputy first approached the man who was killed.

One witness described a “quick and scary” fight to nola.com. The witness said a deputy and a man were fighting on the ground between the highway and parallel railroad tracks when another deputy standing nearby fired his gun.

Harrell said the deputy was injured by two “strikes” to the rear of his head, but he did not elaborate on what weapon was used.

The Sheriff’s Office has turned over the investigation of the shooting to the State Police.

Two hours after the shooting, the man’s body could be seen lying behind a Sheriff’s Office vehicle near the tracks.

Residents nearby watched the scene and waited for the chance to re-enter their blocked-off homes.

As of Tuesday evening, Harrell said, authorities were still trying to identify the man who was killed.

A Sheriff’s Office spokesman said the name of the injured deputy would not be released Tuesday.

Editor’s note: This story was changed Sept. 16 to make clear that State Police did not specify that the deputy taken to the hospital was not the deputy who shot the man.
