A man accused of orchestrating Tupac Shakur’s 1996 killing is on trial. Here’s what to know.

Key Points:

• Duane “Keffe D” Davis, charged with murder related to Tupac Shakur’s 1996 killing, is set to go on trial in Las Vegas with jury selection starting Monday; the trial is expected to last about a month.
• Prosecutors aim to prove Davis orchestrated the shooting and provided the weapon, not that he fired the fatal shots, with Davis’ memoir detailing his involvement but not identifying the shooter.
• The trial will feature 35 to 45 witnesses, including former Las Vegas Mayor Oscar Goodman, Shakur’s family members, and gang affiliates, while Davis’ defense plans to call only a few witnesses.
• Marion “Suge” Knight, the only other eyewitness in the car that night and currently serving a prison sentence, has not agreed to testify, though his testimony could be pivotal.
• Speculation surrounds possible celebrity involvement, including Sean “Diddy” Combs, who Davis accused in his book of wanting Shakur and Knight dead; however, Combs has denied involvement and is not listed as a witness.
