Although no one's been convicted for the death of Christopher "Notorious B.I.G." Wallace since his 1997 slaying, it appears a task force made up of local and federal law enforcement agencies is still actively searching for the killer.

According to CNN, two sources close to the investigation say the agencies began to pursue leads again a couple of months ago when they came across new information involving the Los Angeles Police Department, L.A. County District Attorney's Office and the FBI.

Biggie, 24, was killed in Los Angeles on March 9, 1997, after leaving a music industry party. The gunman pulled up to his Suburban driving a Chevy Impala and opened fire on Biggie, who was sitting in the passenger seat.

Six months earlier, a gunman killed rapper Tupac Shakur while he rode in a car driven by Suge Knight, the head of Deathrow Records at the time. Much like Big's case, and as most of you know, that murder remains unsolved also.

Of course, the main theory since the slayings is that both of these senseless murders happened because of an on-going West Coast vs. East Coast feud and their respective labels -- Sean "Diddy" Combs' Bad Boy Records, which Biggie was signed to, and Deathrow, which Tupac was signed to.

Retired Los Angeles Police Detective Russell Poole, who worked on the Notorious B.I.G. case, told CNN he believes Knight was behind Biggie's murder, although he was behind bars for violating his probation at the time of the killing. He added that he retired early from the LAPD, in part, because he was discouraged from following leads in the case that involved police officers, some of who worked off-duty for Death Row Recrds.

"I think I was getting too close to the truth," Poole said. "I think they feared the truth would be a scandal."

Poole said one of the officers he believes is involved in Biggie's death is David Mack, who was sent to prison the same year Biggie was killed for robbing a bank. Mack was released from federal prison on May 14.
