FAB IN TROUBLE

Police are investigating a possible link between Fabolous and the murder of a rapper near a Queens nightclub. The NY Daily News reports:

NYPD detectives aren't sure what role, if any, the Fab might have played in the March killing. A surveillance video shows Fabolous leaving Club Amazura seconds before a mystery gunman shot Greg (G-Baby) Brown in the back.

"[Fabolous] is about to get in the car as the shooting goes down," said a police source who watched the video.

Police and G-Baby's relatives say the rappers - both from Bedford-Stuyvesant - had a longstanding beef, though a source said they'd put it behind them.

"My son was going to talk to Fab in a car, and he got shot three times," grieving mother Roxanne Brown said. "I don't know what's going on. I just want to know who killed my son."

Homicide investigators have yet to interview Fabolous, whose real name is John Jackson, and won't until they get more information on his possible connection to the slaying. Police haven't made an arrest in the March 13 shooting, and Fabolous hasn't been named as a suspect.

G-Baby, 22, was a protégé of rapper Memphis Bleek. Memphis Bleek signed G-Baby to his record label, Get Low Records.

News of the young rapper's murder spread on the Internet after Fabolous wrote about it on Twitter seven hours after the shooting.

"Lost a soldier in the field this morning," he tweeted. "R.I.P. G Baby."

The night of the murder, G-Baby went to Club Amazura in Jamaica, Queens. G-Baby was asked to perform onstage while the crowd of 1,900 revelers anxiously awaited Fabolous' arrival.

Fabolous got there around 3a.m., said former NYPD hip-hop crimes investigator Derrick Parker, who was at the concert helping with security. Fabolous left the stage an hour later, Parker said. Soon after he left the club, there was gunfire at Archer Ave. and 143rd St.

G-Baby was shot in the back, and a person cops said was an innocent bystander was wounded in the groin. The second victim, a 20-year-old man, survived.

Parker has worked with detectives from the 103rd Precinct and the NYPD's intelligence unit acting as a bridge between the hip-hop community and police.

"G-Baby and Fabolous had beef before, but they supposedly squashed all of that," Parker said.
