Tupac Shakur was fatally shot on September 7, 1996, in Las Vegas, Nevada, US and died six days later from his injuries.
But conspiracies have long-since swelled that the hip-hop icon actually faked his death to escape the limelight and go into hiding.
Ahead of what would have been the rap legend’s birthday, a fresh conspiracy has emerged that the Hit Em Up star used a body double to cover up his death.
The theory goes that a man named Devon Clark was approached by the iconic rapper to act as his body double, because he feared he would get attacked.
Devon was chosen, truth-seekers claim, because he was suffering from HIV/AIDs and did not have much time left.
Among those to believe in the theory is YouTube star Danny, who runs channel Wired Up TV.
In a video posted in February, Danny explained: “Tupac told Devon Clark: ‘I’m going to pay you some money if you do me a favour.
“‘Your whole family will be taken care of forever and they will never have to suffer again.
“‘Something is going to happen to me but before it does I need you to do this with me’.”
Danny then added fuel to his conspiracy fire by posting a photo supposedly showing Devon Clark in a second video in May.
“We came across this picture, right here,” he explained.
“That is Tupac, that is Big Stretch in the passenger seat and Mr Devon Clark right there with him.”
“Devon” bears a startling similarity to Tupac, as he stands outside of the car, although there is no concrete proof whatsoever of his identity.
Danny also believes Tupac’s own dad, Billy Garland, may have hinted at the cover-up in an infamous interview.
In a clip of the chat seen above, Billy is seen recalling seeing Tupac in the hospital after the shooting.
He says: “I saw something that resembled my son, but didn’t look like my son.”
According to Danny, Billy was left confused because the person in front of him wasn’t his son at all and was, in fact, Devon.
But the so-called truth-seeker isn’t the only one who believes in the theory.
Another YouTuber – Thugavelli – posted a clip back in September in which he analysed the now-famous CCTV footage of the fight in the MGM Grand hours before Tupac’s death.
The fight involved Tupac and his entourage inflicting a beating on Orlando Anderson, who was a member of a rival gang.
It led to Anderson being seen as the prime suspect in the rapper’s murder case – after cops identified his revenge motive – but charges were never laid against him.
In his analysis, Thugavelli claimed the fight was a set-up to let Tupac escape and be replaced by Devon.
The footage shows the rapper leaving the room, before appearing to return moments later to fight Anderson.
Thugavelli points to the moment Tupac reappears as being unusual.
“Everyone else comes in from the back-right entrance but the body double enters from the left behind the plinth,” he claimed in the clip.
“It would be impossible for the real Tupac to enter from the left as he and the Deathrow crew were leaving the fight from the right entrance.
“Exit Tupac, enter Makaveli (aka Devon Clark).”
As bonkers as the theories surrounding the legendary rapper are, there is no doubt that they will continue to rumble on for years to come.
