Duane Davis said he'd never told anyone the story. Jurors just heard him walk police through the night Tupac was killed

Duane "Keffe D" Davis leaned back in his chair at the defense table and appeared to watch the screen without expression as jurors at his murder trial heard his recorded voice describe the night Tupac Shakur was killed.

"Nothing you say today will be used against you," Greg Kading, who was a Los Angeles Police Department detective, told Davis in the recording.

The hours-long interview — part of a proffer agreement related to drug charges — was recorded in July 2008, when Davis sat down with LAPD detectives investigating the murder of Christopher Wallace, the rapper known as the Notorious B.I.G.

"I ain't never told nobody that story," Davis said in the recording.

Davis told investigators, "If we would have been on my side, I would have blast."

At another point, detective Daryn Dupree jokes about the fame awaiting Davis if he shares what he knows: "Oprah's going to be, like, 'Mr. Davis, we really appreciate it.'"

"Everybody was a suspect at that time," Dupree testified Thursday.

Prosecutors allege Davis handed a gun to his nephew, Orlando "Baby Lane" Anderson, who fired at Shakur from the back seat of a white Cadillac.

Attorneys for Sean "Diddy" Combs, who has faced years of unproven insinuations about his alleged involvement in Shakur's death, pushed back on claims made in court.

"Davis has denied his own claims, maintaining that he made the statements to gain fame and notoriety and that they were not true," Combs' representatives said in a statement.

Court will continue Friday morning and prosecutors are expected to play another recording from 2009.
