'I know who killed Tupac': Ex-gangster Keefe D confesses in new Netflix documentary he knows who pulled the trigger

A onetime gangster linked to the 1996 murder of Tupac Shakur has admitted he knows who shot the rapper dead.

Duane Keith Davis - also known as "Keefe D" - is the uncle of the number one suspect in the case, Orlando Anderson.

Davis claimed he was in the car in Las Vegas when a fellow passenger shot the 25-year-old music superstar four times, the Daily Mail reports.

Now a new Netflix documentary - Unsolved, the Tupac and Biggie Murders - has been released, based on the work of an LAPD investigative task force led by ex-cop Greg Kading. Kading's findings were based on a tape of Davis recorded under immunity.

It also shows an interview with Keefe D being asked if "Big Dre, Orlando. Who shot Tupac?"

He replies saying: "I'm going to keep it for the code of the streets. It just came from the backseat bro."

Executive producer of Netflix's Unsolved, Kyle Long, has called for Las Vegas police department to pursue Keefe D, according to the Daily Star.

"He went live on television and confessed to being an accessory to murder and the Las Vegas PD, as far as I know, is doing nothing about it," said Long.

"I just think it's outrageous."

Speaking months ago before the Netflix show, in a separate documentary titled Death Row Chronicles, Davis said he is now ill and wants to reveal what happened on the sad September night.

"I was a Compton kingpin, drug dealer, I'm the only one alive who can really tell you story about the Tupac killing," Davis said.

He added: "People have been pursuing me for 20 years, I'm coming out now because I have cancer. And I have nothing else to lose. All I care about now is the truth."

However, again he did not name the killer.

Tupac died six days after his shooting on September 7.

He had been driving with Death Row Records chief Suge Knight when a gunman in a white Cadillac is said to have pulled up beside his BMW, which was stopped at traffic lights.

The star was then shot in the chest, thigh and arm.

But nobody has been convicted of his killing.

Davis said his nephew was attacked and beaten by Tupac and members of his crew, prompting his desire for revenge.

Anderson was reportedly affiliated with the notorious Crips gang, while some of Tupac's associated were linked to their equally notorious Bloods rivals.

Anderson died in a gang shooting in 1998, but always denied involvement in Tupac's murder.
