New details are emerging concerning the murder of Cali Swag District member M-Bone, as the slain hip-hop star's girlfriend is speaking out on the case.

M-Bone's girlfriend, whose name was not revealed, tells TMZ that M-Bone took her car out after she picked him up from the airport. He apparently was in Inglewood, Calif., heading to a studio to record music, when she got the call that he had been shot in the head. He was standing outside a liquor store by his girlfriend's car when he was murdered.

The girlfriend also says that M-Bone was receiving threats by a neighbor who was jealous of Cali Swag District's success. The man apparently lives in the same apartment complex that M-Bone resided in with his girlfriend.

Meanwhile, a man nicknamed "Bubba," who appeared as a dancer in Cali Swag District's video for their hit 'Teach Me How to Dougie,' was apparently a witness to the shooting. He supposedly was inside the car and was struck by broken glass in the face when M-Bone was shot.

Police officers are still looking for the killer, who fled the scene after the shooting.
