Rapper Big Paybacc was shot dead in a MCDonald's branch in Palmdale, California on Thursday (06Nov14).

The hip-hop star, real name Habeeb Ameer Zekajjm, was dining in the fast food chain when a man walked in and fired the fatal shot.

Jessica Jefferson, Zekajjm's girlfriend, tells CBS News, "For them to be that bold to run up to someone in a MCDonald's in daylight, in front of people, kids you know, and to just take some kind of vengeance on somebody... it's inhumane. Everybody loves him... He's a good rapper, and he has so many followers, and people who stand behind him. He really is a good, solid person."

A spokesman for Los Angeles County Sheriff's Department says in a statement, "There was no altercation... This guy just walked in through one door, shot him and left out another door. So it looked like something personal. He had something against this individual. It wasn't like he shot up the MCDonald's. He just shot him and left."

The 38-year-old musician was signed to Baymaac Records in 2010 and once started a feud with Lil Wayne after taking offence to a comment he made about infamous street gang The Crips.
