The 60-year-old man arrested last week in the 1996 killing of rapper Tupac Shakur appeared in court for the first time Wednesday in Las Vegas, where a judge opted to delay his arraignment for at least two weeks.

Duane Keith Davis, known as "Keffe D," was expected to be arraigned on a charge of murder with use of a deadly weapon in a gang-related homicide. But when he appeared in court, dressed in a Clark County Detention Center jumpsuit, Davis said his defense attorney needed two weeks to arrange to be present.

State Judge Tierra D. Jones granted a continuance, delaying the arraignment until October 19.

Davis is accused of orchestrating the shooting that cut short the life of Shakur, a 25-year-old trailblazer whose brief, prolific career cemented his legacy as one of the most influential hip-hop artists of all time. His untimely death added a grim layer to that mystique, and for years it had been the subject of conspiracy theories.

Shakur's slaying also was the subject of a decadeslong investigation by police that culminated last week with Davis' arrest following his indictment by a grand jury. He is the only suspect in the case still alive, police said.

For years, Davis has placed himself at the scene of the crime, stating publicly he was in the front seat of a white Cadillac when it pulled up alongside Shakur's car and shots rang out from the back seat. Shakur was shot four times and died six days later.

Authorities have cast Davis as the alleged ringmaster of the plot to kill Shakur, which they contend was retaliation for an attack on Davis' nephew, Orlando Anderson, that stemmed from a broader conflict between two gangs in Compton, California.

Shakur and Marion "Suge" Knight, then-CEO of Death Row Records, were affiliated with the Mob Piru gang, said Jason Johansson, the homicide lieutenant of the Las Vegas Metropolitan Police Department, at a Friday news conference. Davis and Anderson were affiliated with the Southside Compton Crips, Johansson said.

At the time of the fatal shooting, Shakur was in Las Vegas to see Mike Tyson box at the MGM Grand Hotel, an event that was also attended by Davis and his nephew. While leaving the fight, members of Death Row Records kicked and punched Anderson near an elevator bank inside the MGM, Johansson said, playing surveillance footage that showed Shakur and Knight among the participants.

Afterward, Davis "began to devise a plan to obtain a firearm and retaliate against Suge Knight and Mr. Shakur," Johansson said. Davis got a gun, then got into the white Cadillac with Anderson, Terrence Brown and Deandre Smith, the lieutenant said.

Anderson and Smith were in the back seat, according to a copy of the indictment. And at some point, Davis provided the gun to the back-seat passengers, Johansson said.

Then, someone pulled the trigger -- though the indictment doesn't say who. Either way, Davis "was the shot-caller for this group of individuals that committed this crime," Johansson said.

"He orchestrated the plan that was carried out to commit this crime," he said.

Anderson denied involvement to CNN before his death in a 1998 gang-related shooting.

Davis confessed to his role in the crime in 2009, but authorities couldn't bring charges due to a proffer agreement -- in which a suspect agrees to provide potentially useful information in an investigation that generally cannot be used as evidence against the suspect -- a former detective on the case, Greg Kading, told CNN on Friday.

The investigation was "reinvigorated" in 2018, Johansson said, in part thanks to "Davis' own admissions to his involvement." Authorities felt it was their last opportunity to solve the case and bring charges, he said.

Police in July searched the Henderson, Nevada, home of Davis' wife, looking for writings or documents related to Shakur's murder, according to an affidavit requesting a search warrant. They seized a copy of Davis' memoir, in which he wrote about street gang life and the shooting of Shakur, describing himself and Knight -- in prison on a manslaughter charge in an unrelated case -- as the only two living witnesses to the shooting.
