Duane Davis, who goes by the nickname “Keffe D,” wrote a tell-all book in 2019 laying out his role in the fatal shooting of hip-hop legend Tupac Shakur.

The book, “Compton Street Legend,” opens in Las Vegas on the night of September 7, 1996, with a play-by-play account of his plan to confront Tupac and Death Row Records CEO Marion “Suge” Knight in retaliation for an earlier fight. Davis wrote that he got a gun, hopped in a Cadillac with three others, and drove around looking for the pair. They spotted Tupac in a car and then pulled up next to it, he wrote.

“No words exchanged, the time for talking had passed, the sh*t was about to go down!” he wrote.

That version of events now represents the key evidence against Davis as he prepares to stand trial in one of America’s most notorious unsolved murders. Prosecutors say Davis was the “shot caller” of the group that fatally shot Tupac and wounded Knight in 1996 and is the only person among them still alive.

The prosecution’s case is largely built on the defendant’s own words, including his book, podcast and documentary interviews and statements to police. The jury will not have a murder weapon, getaway vehicle or surveillance video of the shooting – but they’ll have his statements.
