"[Ramirez] worked for him," Kelly said at a scathing news conference Wednesday. "I'd think he'd be knocking on the door...if your employee's murdered in front of you, you think you might want to talk to police."

The commish groused that the hip-hopster's silence has made it difficult for detectives to solve the murder and may result in the case going before a grand jury, where Rhymes and other witnesses would be called to answer questions under oath. In that scenario, if the rapper decides to obstruct, he could face the same fate that befell Lil' Kim.

"I find it quite disturbing," Kelly continued. "This individual was shot in front of a lot of people."

Ramirez was killed around 1:30 a.m. outside an industrial warehouse as Rhymes and an all-star entourage, including DMX, Missy Elliot, Mary J. Blige and G-Unit members Lloyd Banks and Tony Yayo, were filming a music video for a remix of his new single, "Touch It."

According to authorities, an unknown assailant fired more than a dozen bullets into a crowd of nearly 500 on-set extras, hitting Ramirez in the chest. The perp managed to drive off without being caught. Detectives recovered a semi-automatic pistol, believed to be the murder weapon, from an adjacent lot. No suspects have been identified and no arrests have been made.

The boys in blue theorize the shooting had something to do with a beef between Yayo and a producer, whom Allhiphop.com identified as Ruff Ryders president Swiss Beatz. Yayo reportedly had a confrontation with studio security earlier in the evening and police believe the trigger man might have been an acquaintance of Yayo who may have even have left the scene in the G-Unit star's vehicle.

The 29-year-old Ramirez, who had been working for Busta since the mid-1990s, was unarmed at the time and is thought to have simply gotten in the way.

Investigators are seeking a court order to obtain video footage taken inside the warehouse that night in the hopes of identifying a suspect in the killing.

Rhymes' camp has refused to comment on Kelly's remarks. However, the "Gimme Some More" emcee did release a statement saying Ramirez was "not only security for me, but he was a friend, one of the rare friends that you come across that you can trust with your life."

Rhymes attended a wake last week at a Manhattan funeral home for Ramirez, who left behind a wife and three children.
