Murdered Cali Swag District member M-Bone real name may have been targeted after a Twitter war over a girl ... sources connected with the group told TMZ.
Tmz sources say M-Bone's friends have been in touch with cops, telling investigators after he got back to L.A. from his tour, he got involved with a girl. M-Bone's friends say a guy who lived in the woman's building didn't like the relationship, and allegedly began threatening M-Bone via Twitter.
Tmz were told M-Bone did not back down and the two men started cyber smack-talking each other.
TMZ has learned ... the black car in which M-Bone was shot is registered to the woman.
Cops are trying to figure out why M-Bone was driving the woman's car and whether the cyber war is in any way related to the shooting.
Witnesses tell how the shooter fired, left, then pulled a U-turn and came back around, possibly to see if he hit his target. So it might not be random, as first suspected.
