WHO SHOT BIGGIE & TUPAC? is an investigative crime special examining two of the greatest murder mysteries in pop culture history. The special, which digs deep into the entangled murders of hip-hop’s most legendary adversaries – rappers Tupac Shakur and Biggie Smalls – airs Sunday, Sept. 24 (8:00-10:00 PM ET/PT) on FOX. The two-hour investigation will be led by actor and rap music icon Ice-T and award-winning journalist and documentarian Soledad O’Brien.

Biggie and Tupac: two larger-than-life personalities – and former friends – were gunned down within months of each other in the late 1990s. Shakur was fatally shot in a drive-by shooting in Las Vegas on September 13, 1996. Smalls, born Christopher George Latore Wallace, was killed by an unknown assailant in a drive-by shooting in Los Angeles on March 9, 1997. It has been 20 years since their murders, and no one has been held accountable. The plot-twisting mystery surrounding their deaths, combined with allegations of police corruption, gang connections and a fierce rap rivalry, are all theories about what might have played a role in their untimely deaths – and what might have resulted in a failure to close their cases. Both murders remain officially unsolved.

WHO SHOT BIGGIE & TUPAC?, from Critical Content, the producers of last season’s “The Case Of: JonBenét Ramsey,” will lead viewers through an investigation re-examining these legendary homicides by uncovering new details and revealing never-before-heard accounts. The special will feature interviews with former private investigators, police officers, informants and hip-hop insiders, including Doug E. Fresh, Funkmaster Flex and former Death Row Records executive Suge Knight. For the first time ever, the best friends of Tupac and Biggie – Lil’ Cease and E.D.I. Mean – will reunite on camera to talk about the friendship between the two rappers, their untimely deaths and the East Coast/West Coast fallout. Additionally, an exclusive, never-before-released audio recording of Biggie talking about the shooting of Tupac will be unveiled. The special also will focus on how both artists lived and what those lives meant, as the 20th anniversary of these unsolved mysteries is marked.
