Three other victims, a female and two males were also shot and transported to UMMC [University of Mississippi Medical Centre] for medical treatment. Their injuries are not life threatening", Hinds County Sheriff Lee D. Vance said.
According to the press release citing the preliminary investigation findings, the shooting occurred after a fight inside the M-Bar Club between the suspect and at least one other person.
