(AllHipHop News) A witness to the slaying of 22-year-old Brooklyn, rapper Greg G-Baby Brown claims the rapper was assassinated in front of a packed nightclub in March of 2009. G-Babys mother claimed Fabolous and her son had a longstanding feud that was supposed to have been put to rest. "My son was going to talk to Fab in a car, and he got shot three times," Roxanne Brown told The New York Daily News. "I don't know what's going on. I just want to know who killed my son."According to Ms. Brown, her son was going to meet Fabolous the night he performed at Club Amazura. Another source said that G-Baby was supposed to perform with the rapper the evening in question. The unnamed source, who was also shot, claimed that as the shooting broke out, G-Baby ran. But a gunman followed G-Baby and shot him three times in the back. Another innocent bystander was wounded in the groin, with as many as 10 witnesses nearby. "There was a whole bunch of people on the corner, like 10 people," the source also told The New York Post. "G-Baby was next to me. When I turned around, I got hit. I heard four shots. G-Baby ran. They started shooting at him. They were targeting him.The witness said the Bed-Stuy native, who was signed to Memphis Bleeks Get Low Records, collapsed in front of Fabolous van and died. Bouncers for Club Amazura allegedly moved G-Babys body so that Fabolous and his entourage could leave the venue. Police are investigating if Fabolous had any role in the shooting, which they believe was organized. G-Baby and Fabolous had beef before, but they supposedly squashed all of that," said concert attendee and former NYPD hip-hop crimes investigator Derrick Parker, aka The Hip-Hop Cop. Police have not questioned, or named Fabolous as a suspect in the murder of Greg G-Baby Brown.
