An Orleans Parish grand jury has indicted two men in connection with a mass shooting in Central City last year that left five people wounded and one bystander dead.

Authorities allege that Brandon “Pooh” Butler, a 20-year-old former standout wide receiver for the Landry-Walker High School football team, and Darion Audrict, 21, were behind the gang-related Sept. 11 bloodbath at South Claiborne Avenue and First Street.

Earnest McKnight, a 63-year-old grass cutter who had stepped outside to buy a pack of cigarettes, was killed, and five other people were wounded.

Butler and Audrict were each charged Thursday with second-degree murder, five counts of attempted second-degree murder and one count of conspiracy to commit second-degree murder. Both were ordered held in lieu of $2.75 million bail.

Butler was already in custody on federal charges. Audrict was arrested Thursday, according to court records.

In January, an FBI agent labeled Butler a suspect in the shooting as well as in a drug-related murder attempt blocks away in Central City.

A state and federal anti-gang task force had been watching Butler and others in an alleged drug ring since August, according to a court filing from the FBI agent. At the center of the investigation was a house he said was used to stash guns and drugs at 2410 Josephine St., half a mile from the site of the Central City shooting.

Butler was arrested on gun and drug charges in August. But he was free on bond when the mass shooting took place.

Audrict had a criminal history as well. He pleaded guilty in 2015 to cocaine possession, unauthorized entry of an inhabited dwelling and resisting an officer in connection with an arrest two years earlier.

A steady drumbeat of gun violence has continued in Central City since the mass shooting. On Feb. 10, five people were wounded and a woman who had just immigrated from Honduras was killed in a shooting at Dryades and Second streets.

Police have not announced any arrests or suspects in that incident.
