But, according to many conspiracy theorists, it is because there was no murder and, like many celebrities before and after him who went to an early grave, he faked his own death.
The 300-pound rapper, whose real name was Christopher Wallace, was shot dead in a drive-by execution in Los Angeles on March 9, 1997, at the age of just 24.
An unknown black male driving a Chevrolet pulled alongside the music legend and fired a hail of bullets at his SUV.
He was shot four times and later died of his injuries.
It was just six months after the similar execution of rapper Tupac Shakur, 25, who was shot in a car in a drive by shooting in Las Vegas, Nevada, on September 7 1996, and died six days later.
that case has never been solved and even more conspiracy theories abound that Tupac is also still alive and faked his own death.
Videos on YouTube claims bullets did not penetrate into the interior of the car and there was no blood inside.
They also point to suggestions relatives and friends filmed grieving during interviews about his death were not actually crying.
Outlandish theories that Biggie survived the shooting have been doing the rounds online for years.
Many of the theories suggest a link to the murder of Tupac Shakur, because of similarities in the drive-by shootings and the two’s involvement in hip hop rivalry between the scenes of the East Coast and West Coast USA.
East Coast Wallace was from Brooklyn and his label, Bad Boy Records, was in New York.
Tupac was also from New York but his label, Death Row Records, was in Los Angeles, on the West Coast.
Other theories concern a CIA involvement or a police cover up.
The conspiracy theories were fuelled this year when an image taken at a party which it was claimed showed the Notorious B.I.G., his stage name, surfaced online.
Initially it was thought the picture had been taken at a bachelor party in the Greek island of Crete.
Kitojo, who appears to live in the UK, shared the picture with the caption: “I don’t know if I was too drunk last night but I swear biggie came to my bachelor party… Biggie is alive… #hangoverpt4 #biggieisalive.”
Shocked fans of the fallen hip hop icon were rocked with disbelief over the photo.
Most agreed the suited and booted man, wearing a open beige jacket over a pristine white shirt, bore an uncanny resemblance to Big Poppa, in their remarks in the comments sections of social media.

But, this particular sighting was soon laid to rest when the real man in the picture came forward.
Jordan Anderson, 21, from Leicester, could not believe he became an internet sensation after the “drunken” selfie of him partying in Brighton emerged online.
The Biggie Smalls doppelganger, a music producing undergraduate at Northampton University, said he “couldn’t believe it” when the bizarre theory gathered pace.
He said: “I was on the way to rehearsal when a friend forwarded me a screenshot of the article.
“I thought, this is crazy, crazy. I couldn’t believe it, I was like ‘oh my days’.”
But, he said it was not the first time he was compared to Biggie.
Other videos on YouTube show alleged Biggie Smalls alive and well long after his death, including seated at an Eminem gig in 2010.
But, in truth, there is no real evidence to suggest Biggie is still alive and all theories have been dismissed as pure fiction.
