EXCLUSIVE: Prosecutors Set to Unveil Bombshell 'Long-Buried' Hotel Reservation That Places Gang Boss Duane 'Keffe D' Davis at the Scene in Las Vegas on the Fateful Night Tupac Shakur was Gunned Down

The man accused of orchestrating the murder of Tupac Shakur has claimed he wasn't in Nevada when the rap icon was gunned down in Las Vegas in 1996.

But RadarOnline.com has learned prosecutors in the case are ready to drop some long-buried evidence that allegedly places former gang member Duane "Keffe D" Davis at the scene of the crime.

Shakur was shot four times by an unidentified assailant in a drive-by shooting on the Las Vegas strip on September 7, 1996. He died six days later at age 25.

More than twenty-seven years later, Davis was taken into custody. The 63-year-old's trial is set to begin Monday, August 10, but in a jailhouse interview with KLOS just before his day in court, Davis insists he had "nothing to do with nobody’s murder."

However, prosecutors say Davis' wife made a hotel reservation in Sin City in her name when the murder occurred, and they can prove it. Investigators said a room at the then-Monte Carlo Resort, now Park MGM, was booked in the name of Paula Clemons.

Investigators shared they had been poring over hotel records, looking for names of known gang members. Clemons' reservation did not originally raise any red flags, as she reportedly was not a gang member at the time.

Prosecutors additionally said Davis previously gave a homicide detective a statement in 2009, in which he "attempted to elude responsibility for the murder of Shakur," but reportedly admitted that he was in Las Vegas at the time of the murder for a Mike Tyson fight.

As Radar has reported, the fateful night all started with a brawl at the MGM Grand hours earlier, when members of a rival gang attacked Davis' nephew, Orlando "Baby Lane" Anderson, after the fight.

Davis allegedly confessed to the crime in his explosive tell-all, COMPTON STREET LEGEND, writing that after Anderson's beatdown, he gathered up some fellow gang members and went out for revenge.

Before long, Davis and his crew caught up with Shakur and the shooting began.

"Tupac made an erratic move and began to reach down beneath his seat," David wrote. "It was the first and only time in my life that I could relate to the police command, 'Keep your hands where I can see them.'"

"Instead, Pac pulled out a strap; that’s when the fireworks started. One of my guys from the backseat grabbed the Glock and started busting back."

Years later, Davis tried to explain his admission to the killing in the book was just a ploy to make money for his family.

Davis has remained in custody on $750,000 bail since he was arrested in connection with Shakur's murder. His attorney, Carl Arnold, also indicated his client made false public statements about the killing and should not be taken seriously.

Additionally, Arnold alleged that Davis' constitutional rights were violated after his previous confessions.

"Mr. Davis cooperated with law enforcement over the course of more than a decade, relying on repeated assurances that his statements would not be used against him – yet those very statements now form the core of the State's case," Arnold said in a statement.

He also stood by Davis' claim that he wasn't in Nevada at the time.
