The deaths of Tupac Shakur and Christopher Wallace aka Notorious BIG are two of the most mysterious cases in hip hop history. Even after 15 years of local and federal police investigations and numerous conspiracy theories, the truth behind who actually killed one of them has never surfaced. Well, CNN’s Anderson Cooper has cracked open the case files again due to new clues surfacing on the death of Christopher Wallace.

Per the AC360 blog:

A task force made up of local and federal law enforcement agencies is actively pursuing leads into the 1997 slaying of hip hop artist Christopher Wallace, better known as Biggie Smalls or Notorious B.I.G., according to two sources familiar with the investigation. According to one law enforcement source, the investigation into the 13-year-old unsolved case was “reinvigorated” months ago as a result of new information, but the source would not elaborate further because of the ongoing investigation that includes the Los Angeles Police Department, L.A. County District Attorney’s Office and the FBI.

On March 9, 1997, Smalls, 24, was shot and killed when leaving a music industry party at the Petersen Automotive Museum in Los Angeles. Los Angeles police said a lone gunman in a Chevy Impala pulled alongside the suburban and opened fire on Smalls, who was in the passenger seat. Witnesses described the suspect as being an African-American man wearing a suit and bow tie.

The main theory behind Smalls’ shooting was payback in a so-called rap war between East and West Coast hip hop artists and their record companies-Bad Boy Entertainment in New York, which represented Smalls, and Death Row Records, headed by Marion “Suge” Knight, in Los Angeles. Six months earlier in Las Vegas, a gunman opened fire on a car driven by Knight, killing one of his top artists Tupac Shakur. That murder remains unsolved also.

Hopefully, this new information will solve Biggie’s murder…finally.
