Las Vegas \u2014 The man who prosecutors say orchestrated the 1996 killing of rap icon Tupac Shakur is scheduled to go to trial Monday, almost 30 years after the fatal drive-by shooting in Las Vegas.Duane "Keffe D" Davis, 63, faces a single count of murder with a deadly weapon with the intent to promote, further or assist a criminal gang in Shakur\u0027s death. He\u0027s been jailed since late 2023 and has pleaded not guilty. For decades, Shakur\u0027s unsolved killing has gripped hip-hop fans. He\u0027s considered one of the most influential rappers of all time with songs that speak to the human experience of love, heartache and familial relationships. When Shakur died, he was in the midst of a fierce battle for dominance in a music scene increasingly shaped by rival gangs. The trial, which is expected to last about a month, likely won\u0027t reveal who pulled the trigger. Instead, prosecutors hope to prove that Davis was the shot caller and provided the weapon.Gunfire came from the Cadillac that Davis was in, and he\u0027s one of the only people there that night who is still alive. Prosecutors say if Davis hadn\u0027t written explicitly about the killing, or talked about it in interviews, it\u0027s likely no one would have been charged.How Shakur\u0027s killing unfolded \u00a0On Sept. 7, 1996, Shakur was in the passenger seat of a black BMW and Death Row Records co-founder Marion "Suge" Knight was driving. They had just watched Mike Tyson knock out Bruce Seldon and were headed to a nightclub where Shakur was scheduled to perform. But at a red light near the Las Vegas Strip, a white Cadillac pulled up beside them and gunfire erupted. Shakur was shot multiple times and died six days later, while Knight survived with minor injuries. Knight is serving a 28-year prison sentence for a fatal hit-and-run. The case went cold until Davis began making public statements about his involvement as a leader of the South Side Compton Crips. In 2019, he published a tell-all memoir. The book, along with interviews Davis gave, revived the police investigation. Davis\u0027 defense attorneys argue there is no evidence he directed the shooting and the state relies on witnesses who weren\u0027t there. The defense said Davis left the narcotics trade in 2009 and worked a steady job before illness forced him to retire in 2014. For Shakur\u0027s family, the last 30 years have been exhausting and stressful, his stepbrother Maurice "Mopreme" Shakur said. Sitting through the trial will be retraumatizing, Shakur said, but he\u0027s "cautiously optimistic" justice will come. "I hope that the trial is fair, and we find out the truth," he said.Gang rivalry behind slaying? \u00a0Hundreds of pages of grand jury transcripts portray Tupac Shakur\u0027s shooting as a culmination of a longstanding feud between rival record labels Death Row Records and Bad Boy Records and rival gang sects Mob Piru and South Side Compton Crips. Witnesses said South Side Compton Crips hung out with and provided protection to Bad Boy Records, which was founded by Sean "Diddy" Combs and included rappers like The Notorious B.I.G., or Christopher Wallace. Mob Piru, part of the larger Bloods gang, was associated with Death Row Records, which featured rappers like Shakur, Snoop Dogg and Dr. Dre. The rival gangs fought and retaliated against each other both before and after Shakur\u0027s death. Prosecutors allege Davis orchestrated the shooting to get revenge after Shakur and his entourage beat up Davis\u0027 nephew, Orlando "Baby Lane" Anderson, at the MGM Grand hours before Shakur was killed.Davis denied any involvement in an\u00a0interview with CBS Las Vegas affiliate KLAS-TV. The prosecutors\u0027 case relies on "Compton Street Legend," the book Davis co-authored about the shooting and his time in the Crips, as well as police and media interviews he participated in. Davis\u0027 attorneys unsuccessfully fought to block the use of the book and a recording of a 2008 police interview in the trial. They argued the book was fictionalized and had a co-author, making it impossible to know which parts Davis wrote. They also argued Davis\u0027 interview with a federal task force investigating the deaths of Wallace and Shakur was supposed to be confidential and not used against him. The memoir says that Shakur and his entourage "crossed the line" when they beat up Anderson. "We couldn\u0027t let no record company studio gangsters do us like that," the book says. Davis was in the passenger seat of the Cadillac and passed a gun to the back seat earlier that night, according to the book. When they encountered Shakur and Knight, Davis claimed to see Shakur reach for a weapon and wrote that "one of my guys from the back seat grabbed the Glock and started bustin\u0027 back." No weapon was found in Knight and Shakur\u0027s car, according to retired Las Vegas police Detective Clifford Mogg, who was assigned to the investigation in early 2018.Shakur relative says justice "unattainable"\u00a0 \u00a0Mopreme Shakur said nothing would bring back his stepbrother. "That would be justice for me," he said. "But we all know that is unattainable." Mopreme Shakur said he wants allegations that Combs was involved to be explored further. In his book, Davis claims that Combs wanted Knight and Shakur killed. Combs has denied having any involvement in Shakur\u0027s death. He\u0027s serving roughly four years in prison after being convicted of prostitution-related charges. Combs\u0027 attorney did not return emailed requests from The Associated Press for comment. Shakur sold over 75 million records worldwide with hits like "California Love," "Changes" and "Dear Mama." His songs spanned from party anthems to deep social commentary. The issues he discussed still resonate with people 30 years later, history professor Jeffrey O.G. Ogbar said. "I can\u0027t think of anyone else in the history of hip-hop who\u0027s had a greater impact in such a short period of ...
