Recent developments in the investigation of Tupac Shakur's 1996 murder have revealed that confidential documents from the Notorious B.I.G. murder case implicate several prominent figures from the 1990s music scene. The files, retrieved by retired Los Angeles detectives, are crucial for building a case against Duane 'Keefe D' Davis, who has been charged with orchestrating Tupac's assassination. According to sources, these documents include witness testimonies from as early as 1997, pointing directly at Keefe D before he made subsequent confessions. Prosecutor Marc DiGiacomo noted that the evidence compiled from thousands of pages could significantly strengthen the prosecution's case, which some insiders believe lacks a viable defense for Keefe D. The information is said to include accusations against major music personalities of the era, although many details may never be made public. This renewed scrutiny of the East Coast-West Coast rap feud's violent background highlights the ongoing complexity of these high-profile murder cases.
