Rapper Mac was indicted on a second-degree murder charge Tuesday related to a shooting at a nightclub in Slidell, La., last month, according to APB News.

The 22-year-old rapper (born McKinley Phipps) faces life in prison. He has not entered a plea and is scheduled to be arraigned Wednesday. He initially was charged with first-degree murder. St. Tammany Parish prosecutor Joe Tosterud could not be reached for comment.

Mac, who is signed to Master P's No Limit Records in Louisiana, was arrested Feb. 22 at his home in Baton Rouge, La. The night before, police said, the rapper shot and killed Barron Victor Jr., 19, during a dispute at Club Mercedes. Victor was attempting to break up a fight, police said. Mac was scheduled to perform at what was billed the "World War Party."

Mac released his debut album, World War III, in the fall. The album debuted at #44 on the Billboard 200 albums chart before fading quickly. The rapper's act and his album are saturated with war imagery, camouflage and references to murder and assassination. His song titles have included "Murda, Murda, Kill, Kill" and "Assassin Nation" (RealAudio excerpt).
