Former Investigator Greg Kading Presents His Theories on the Tupac and Biggie Cases

In early October 2011, a man who had worked as an investigator for the Los Angeles Police Department on the Tupac and Biggie cases came forward publicly. Greg Kading presented his self-published book Murder Rap, which was covered by Complex and the LA Weekly.

What Kading Claims

Kading relied primarily on statements from a Crips member: Duane “Keffe D” Davis reportedly told police that he had been offered a million dollars to kill Tupac and Suge Knight, and that the order came from Sean Combs. According to Kading’s documents, Knight in turn ordered the murder of Biggie in retaliation for Tupac’s death. The report did not contain statements from the accused. Complex pointed out that it remained unclear how reliable the sources were, because some witnesses testified to avoid their own legal trouble.

Biggie’s cousin Lil’ Cease expressed doubts to RapFix. Every few months a new theory surfaced. He did not know Kading, and he did not believe that Combs had ordered Tupac’s death.

What Came of It

Keffe D’s statements played a central role years later: In 2023, he was charged in Las Vegas for the crime, and in 2026 he was found guilty by the jury. The verdict is not final, and an appeal has been announced.
