More than 20 years after the murder of Tupac Shakur, the man who was riding in the same car with the rapper the evening he was shot in a drive-by on a Las Vegas street says he knows who killed the hip-hop star.

The Daily Mail reported that Death Row Records co-founder, Marion "Suge" Knight, is claiming that his ex-wife and a Death Row security chief murdered Tupac, but the "Dear Mama" artist wasn't the intended target. Knight claims that he was actually the person they meant to kill and Tupac was simply "in the way."

A signed affidavit from Knight's lawyer, Thaddeus Culpepper, alleges that his client "has known for many years that Reggie Wright Jr. and his ex-wife Sharitha were behind the murder of Tupac."

But why after all this time would Suge, who for years refused to name names about those responsible for Tupac's death, come forward now?

Apparently his reasoning is due to the 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?"'

Knight was reportedly so perplexed by the findings and told Culpepper that the theories and allegations were true. He also said that Wright Jr. and Sharita planned the hit on him because if he died Sharita would get everything and assume control of Death Row Records.

White Jr. previously denied this claim to AllHipHop and pointed out that those who tried to implicate he had something to do with Tupac's murder have all died in the past decade.

"I believe in karma," he said. "All these people are dropping dead. I keep telling people God don't like ugly. I hope people learn a lesson from this."

So, should we really believe Suge Knight about this or that this documentary, verses others, has finally solved the murder? Perhaps we just want to believe the we will someday know who killed one of rap's biggest and brightest stars even though a case like this may not be solved in our lifetime.
