Nearly three decades after Tupac Shakur died following a 1996 shooting in Las Vegas, the only criminal trial ever brought in the case is underway. Duane “Keffe D” Davis, 63, has pleaded not guilty to murder with a deadly weapon with the intent to promote, further or assist a criminal gang.

Prosecutors do not accuse Davis of personally firing the shots. Their case is that he helped organize the attack and supplied the weapon after a confrontation involving Shakur’s entourage and Davis’s nephew, Orlando Anderson, at the MGM Grand earlier that evening.

Jurors have heard a recording of a 2008 law-enforcement interview in which Davis described being inside the white Cadillac involved in the shooting and identified Anderson as the shooter. Prosecutors say the interview, later media appearances and Davis’s 2019 memoir form a central chain of evidence.

The defense argues that Davis repeatedly exaggerated or invented stories for attention and money, and that investigators failed to independently prove important parts of his accounts. His lawyer has described the prosecution’s version as fiction. Davis’s earlier interview also raises legal questions because detectives made assurances about how information from that cooperation would be used; prosecutors argue later public statements removed any protection.

The trial has also shown the difficulty of litigating a case this old. Several people connected to the events have died, memories have faded and some witnesses have been reluctant to testify. Those limitations are likely to remain central as jurors weigh Davis’s own words against the supporting evidence.

Davis remains presumed innocent. The jury—not decades of speculation around one of hip-hop’s most discussed unsolved cases—will decide whether prosecutors have proved the charge beyond a reasonable doubt.
