Tupac was killed over 20 years ago, yet the people behind his murder remain unknown. That's despite several people claiming that they knew who killed him.
On September 7, 1996, Tupac on his way to a club from a boxing match was shot in his car, and died a week later from internal bleeding.
Now, in a new documentary, it has been revealed that the American rapper knew his killer, but the murder has remained unsolved as the Las Vegas Police Department never wanted to solve it.
The Oxygen-backed programme, Snapped: Notorious, will run for two hours and feature in-depth interviews with the people who were the last to see Tupac alive before he was fatally shot.
Those people include: Danny Boy, Yo-Yo, DJ Mister Cee, Pac's first manager Leila Steinberg and music journalist Toure.
The trailer paints a vivid picture of Tupac's last breaths on his deathbed in a Las Vegas hospital - and when asked if he knew who did it, he nodded his head.
Earlier this year, a new documentary featuring rap mogul Suge Knight tried to lift the lid further on the conspiracy.
Knight, who is behind bars himself on trial for a separate murder charge, was with Tupac on the night he died and, until now, had never previously revealed who he thought was responsible for his friend's death.
Documentary makers, Richard Bond and Michael Douglas Carlin, supposedly have a signed statement from Knight's criminal attorney, Thaddeus Culpepper, which states the story laid out in the film is all true.
Tupac Assassination: Battle for Compton shows a thorough investigation into the death of Tupac and if there was evidence of a cover-up.
A spokesperson for the film said: "Culpepper told Carlin individually that not only did Knight confirm the events portrayed in Compton, which portray Knight was the intended target and Shakur as collateral damage, as true, but also goes onto allege that these 1996 events may have been the first in a history of attempts on Knight's life."

The documentary now hopes to put a final stamp on the mystery that has surrounded the death of Tupac.
