As Emanuel Augustus continued Wednesday to fight for his life, police issued a warrant for the arrest of a 21-year-old man accused of shooting the Baton Rouge boxer in the head.

Christopher Stills is being sought on attempted second-degree murder, felon in possession of a handgun and illegal use of a weapon, said Cpl. L’Jean McKneely, a Baton Rouge police spokesman.

Augustus, 38, also known as Emanuel Burton, has remained in critical condition since he was found lying on Louisiana Avenue near Government Street at around 8 p.m. Monday, said Cpl. Don Coppola, a police spokesman.

Through his decade-long career, Augustus competed against revered fighters like Micky Ward and Floyd Mayweather Jr. before returning to Baton Rouge.

But recently, a longtime friend had told Augustus to quit boxing, in part because he had been badly roughed up in a few of his latest fights. A former trainer of his said Tuesday the ex-fighter had left Texas without a suitcase or driver’s license, and few possessions to speak of.

Augustus was shot near the boxing gym where he first trained while growing up. Police found red boxing gloves near the scene.

There was no new information on the suspect in the shooting, other than he was last seen in north Baton Rouge. Details surrounding the incident remained unclear on Wednesday, Coppola said.
