Suspect arrested in 1996 Tupac Shakur shooting death

A grand jury has indicted Duane Keith "Keffe D" Davis on charges of murder with use of a deadly weapon in connection with the 1996 killing of rapper Tupac Shakur, Las Vegas authorities announced.

Davis, 60, was arrested Friday morning in Las Vegas, according to authorities. His wife's Henderson home was searched in July as part of the ongoing investigation into the shooting.

Shakur was shot and killed while leaving a boxing match on the Las Vegas Strip. His untimely death - the rapper was just 25 - has been the subject of conspiracy theories and a decadeslong investigation.

At a Friday news conference, authorities painted Davis as the ringmaster of a plot to kill Shakur as retaliation after an attack on his nephew. Davis has long placed himself at the scene of the crime, saying he was in the front seat of the white Cadillac that came up beside Shakur's car when shots rang out from the back seat, killing the musician. The rapper was shot four times and died six days later.

"For 27 years, the family of Tupac Shakur has been waiting for justice," said Las Vegas Metropolitan Police Department Sheriff Kevin McMahill at the news conference.

"The investigation started on the night of September 7th, 1996," McMahill said. "It is far from over. It has taken countless hours, really decades, of work by the men and women of our homicide section to get to where we are today."

Jason Johansson, the police department's homicide lieutenant, said the murder was a "retaliatory" attack after a conflict between two gangs based in Compton, California. Shakur and Marion "Shuge" Knight, the former CEO of Death Row Records, were affiliated with the Mob Piru gang in Compton, while Davis was affiliated with the Southside Compton Crips, according to Johansson.
