Keffe D at center of Tupac murder trial as defendant and key witness

Duane 'Keffe D' Davis, the Las Vegas defendant in Tupac Shakur's 1996 murder, is also the prosecution's key witness because the case rests largely on his past statements in a 2019 book, interviews and a police proffer; prosecutors say his accounts are credible, while the defense argues they are false, making for a rare trial dynamic where the defendant also serves as the main witness, with a verdict potentially life in prison.
