The Las Vegas Metropolitan Police on Friday arrested a Nevada man, identified as Duane Keith Davis, also known as “Keefy D” or “Keffe D.”

We gathered that the man is believed to be the last living suspect investigated in the 1996 shooting of Tupac Shakur.

According to NBC News, law enforcement sources revealed that Davis was arrested in relation to the long-unsolved case of the slaying of Shakur, even though it was not immediately clear what charges would be filed against him.

The 25-year-old rapper was fatally wounded in a drive-by shooting on 7 September 1996 in Las Vegas and died on 13 September.

The report noted that a police statement revealed that the Las Vegas Metropolitan Police Department Sheriff Kevin McMahill and Clark County District Attorney Steve Wolfson scheduled a 3:30 p.m. ET news conference to discuss “an arrest made in the murder of Tupac Shakur,”  

Of the four people thought to be in the car that attacked Shakur, Davis is the last known survivor.

Orlando Anderson, Davis’ nephew, has long been suspected of pulling the trigger. Anderson was killed in a 1998 gang shooting in Los Angeles.

In July, a search warrant was issued on Davis at his home near Las Vegas, looking for laptops and other electronic devices in connection with the decades-long investigation.

It was said that Shakur and his entourage were in Las Vegas for a heavyweight bout between Mike Tyson and Bruce Sheldon. The rapper and his friends were stopped near East Flamingo Road and Koval Lane when a Cadillac pulled alongside, and someone inside that car opened fire, mortally wounding Shakur.

“I ended up pulling Tupac out of the car,” retired LVMPD Lt. Chris Carroll told NBC affiliate KSNV over the summer, just after the search warrant was served on Davis. “I spoke to him. He was still alive. He was still breathing.”
