More than 20 years ago, beloved West Coast rapper Tupac Shakur was shot down in Las Vegas, marking the death of a great and the end of an era. While he was tragically taken from us too soon, the 25-year-old Shakur has had an active post-mortem, headlining at Coachella in holographic form and sparking some of the greatest conspiracy theories in pop culture history.

The question of who killed Tupac—a trusty conversation topic across college dorm rooms and Twitter feeds—has gone unanswered for over two decades, but not for lack of trying. One well-worn theory is that the FBI shot Tupac, and were also responsible for Biggie Smalls’ murder six months later. Less cynical fans would like to think that Biggie and Tupac, while enemies by the end of their short lives, have been reunited in fake death and are enjoying a permanent vacation in a secluded town in New Zealand. If the idea of two of America’s greatest rappers denouncing their fame and fortune to become unemployed Kiwis sounds far-fetched to you, you’re not alone. Former LAPD cop Greg Kading believes that Sean Combs hired a million dollar hitman to take out Pac, and that Death Row Records’ Suge Knight, who was in the car with the rapper the night he was murdered, retaliated by ordering the attack on The Notorious B.I.G.

Then again, some backseat detectives believe that Knight was actually responsible for Tupac’s murder himself, with rumors swirling that the rapper was planning to leave Death Row Records and start his own label. Controversial former N.W.A manager Jerry Heller, now deceased, confirmed in a 2015 interview that Suge Knight “unquestionably put the hit out” on Shakur, adding, “I think Suge got what he deserved.”

While Knight emerged physically and legally unscathed from the two ‘90s shootings, he’s currently facing life in prison after a 2015 Compton hit-and-run. According to a statement from the Los Angeles County District Attorney’s Office, “Following an altercation on Thursday outside a Compton restaurant, Knight allegedly was driving his truck when he ran over two men standing in the parking lot.” While Knight’s lawyer has said that the incident was unintentional, Knight's other colorful crimes include repeated parole violations, aggravated assault, and second-degree robbery, not to mention numerous traffic violations.

Of course he knows, since he is the one who ordered the hit.
