Tupac Shakur's killing in a drive-by shooting has been clouded in mystery, with conspiracy theorists suggesting that it was hip-hop icon Suge Knight who was behind the murder of the All Eyez On Me hitmaker. Tupac was 25 when he was gunned down in Las Vegas on September 1996.

The Death Row Records co-founder - who is currently in jail and facing murder charges in a separate case - has now named two people who he thinks are responsible for the death of the rapper.

According to his attorney Thaddeus Culpepper's affidavit, Knight has alleged that his ex-wife Sharitha and Reggie Wright Jr (former Death Row Records security chief) were responsible for Tupac's murder and that they also tried to kill him.

"Knight has known for many years that Reggie Wright Jr. and his ex-wife Sharitha were behind the murder of Tupac and attempted murder of Knight," Knight has said in the affidavit, according to Daily Mail.

Knight apparently named Wright Jr and Sharitha as the ones responsible for Tupac's murder after he came to know the "salient points" of a new documentary - Tupac Assassination: Battle for Compton.

"When our book came out and we were working on the movie, we gave the salient points of the book (Tupac: 187 The Red Knight) to Thaddeus Culpepper, who read them to Suge Knight," said co-director Richard Bond.

"Suge's initial response was, 'Who the hell are these guys?' a source said."He admitted to Culpepper that the theories in the movie were true."

According to the documentary, it was Knight who was the real target of that fatal shooting and that Tupac was just "collateral damage". The documentary has also claimed that shooting happened because Wright Jr and Sharitha wanted to take over Death Row Records, founded in 1991 by Dr. Dre, The D.O.C., Dick Griffey and Knight.

Former LAPD detective Russell Poole told Vice in 2015, "Suge wasn't divorced yet and if he died in that hit, she'd get most of everything... So she went to Wright Jr., who was in charge of Death Row and ran it while Suge was in prison."

Wright Jr. has denied these allegations.
