REQUIEM FOR A DJ:
Fans set up a shrine yesterday outside the Queens studio where Jam Master Jay was gunned down, complete with a tribute scrawled on a sneaker.
November 1, 2002 -- Police fear more violence could follow the execution-style shooting of hip-hop pioneer Jam Master Jay, and rushed to protect a young protégé of the fallen Run-DMC star.
Sources said a rapper known as 50 Cent, who was discovered by Jay and recently signed a million-dollar contract with Eminem's label, was under police protection following the Wednesday-night shooting.
Cops were also guarding other music-industry figures who may be targeted following the killing of 37-year-old Jay, whose real name was Jason Mizell.
"They're going to guard them whether they like it or not, with or without their permission," said one source. "There won't be any murder wars here."
Last night, sources said the slaying may be linked to the 1999 murder of another Queens rapper, Freaky Tah, whose real name was Raymond Rogers.
The triggerman in that murder was from Albany, as is one of the women who was in the studio at the time of Jay's shooting.
And 50 Cent was shot three times in a May 2000 attack in Queens. He had been stabbed two months earlier.
"Cops are going to provide protection to a few people who they believe could be on the unfriendly side of this story," said a source. "This is a revenge kind of thing."
Cops were looking into several previous shootings for clues into the murder of Jay, who was killed by a bullet to the head in his 24/7 Jamaica, Queens, recording studio Wednesday night.
Police believe he probably knew his killer.
The rapper's family gathered yesterday at his Queens Village home to mourn, as friends, including Darryl "DMC" McDaniels, paid their respects.
"The family is confident that the circumstances that led to this event are being investigated and handled in an efficient and professional manner by capable law-enforcement personnel," they said in a statement.
The hip-hop community has been decimated by violence, including the tit-for-tat slayings of rappers Tupac Shakur and Notorious B.I.G., whose murders are unsolved.
Hip-hop insiders said Run-DMC was never associated with the violent style known as gangsta rap.
Cops said they were also looking into other recent cases of violence related to the hip-hop world, including shootings in Fort Greene, Brooklyn, and a gunfight outside a West Village rap radio station.
They said Jay's killer was buzzed in to the studio by someone inside who may have known him, raising the possibility the rapper was set up. There were six people in the studio at the time.
The gunman went up a flight of stairs to a second-floor landing and entered a lounge area where the rap star was sitting on a couch with a close associate, 25-year-old Urieco Rincon, and a female rapper. The three were playing video games. Cops said the room smelled of marijuana.
Cops said Mizell was shot at close range on the left side of his head, leaving powder burns. Rincon was shot in the leg.
Meanwhile, police sources said they were investigating threats against 50 Cent, a 26-year-old former boxer whose real name is Curtis Jackson.
Mizell discovered and recorded 50 Cent several years ago, before his record was picked up by Eminem.
Sources said gang intelligence units specializing in hip-hop violence had talked to California and Florida cops and determined that the young rapper's life could be in danger.
