The person allegedly punched Wagner from behind in retaliation and then continued to punch him until he lost consciousness, police said.
Police responding to the incident found the victim “alone and officers could not speak to him to get any information, let alone contacts,” according to WWL-TV.
The alleged assailant, who is now wanted on a second-degree battery charge, reportedly left the scene with another individual, according to a photo released by the New Orleans Police Department.
While police have not publicly identified Wagner as the victim, his family spoke with WWL-TV and claimed he suffered a traumatic brain injury, which he may not survive.
