Trial begins in Tupac Shakur's 1996 murder case.

Duane 'Keffe D' Davis, 63, stood trial Monday in Las Vegas on a charge of murder with a deadly weapon in the 1996 killing of Tupac Shakur. Davis has pleaded not guilty.

• Shakur was struck four times and died six days after the September 7, 1996 shooting.
• 27 years passed before Davis was indicted in 2023 — the first arrest in the case.
• Three other men alleged to have been in the car with Davis have since died.
• Death Row Records co-founder Marion 'Suge' Knight appears on the prosecution witness list.

Why it matters: Prosecutors say Davis organized the shooting as retaliation after Shakur's entourage beat Davis' nephew at the MGM Grand hours earlier. Under Nevada law, organizing a killing carries the same murder charge as pulling the trigger.

• Davis' 2019 memoir and 2018 media interviews revived a cold case and became the prosecution's central evidence.
• Prosecutor Marc DiGiacomo stated: 'Had he decided to never write the book, he would not, probably, have ever been prosecuted for the crime.'

How 36 sources split on this story

Where they split: The core dispute is whether Davis' memoir and public statements are credible admissions or fictionalized accounts written for commercial gain.

What’s next: Knight has said he does not intend to cooperate if called to testify, per Fox News.

• Co-author Yusuf Jah is on the witness list; he told an investigator he did not believe Davis fully read his own book.
• No account — Davis' or prosecutors' — identifies who actually fired the shots at Shakur.
• Whether Suge Knight will testify and what he would say remains unresolved.
• The killing of Christopher Wallace in 1997 remains unsolved; its connection to this case has not been established in court.
