On October 12, 1978, Nancy Spungen went from being the notorious girlfriend of Sex Pistols bassists Sid Vicious to a victim of a horrific stabbing in New York City's Chelsea Hotel. Spungen was only 20 when she and Vicious were partying with members of the local punk scene. A deluge of drugs and alcohol makes it impossible to know exactly what happened on the night of her death, but while Vicious was pinned with the murder it's theorized that a local drug dealer stabbed Spungen in the abdomen before fleeing the scene and leaving Vicious to take the wrap. Vicious never served time for the murder. He passed away from a drug overdose not long after Spungen's death.

When it comes to unsolved crimes from the 1970s the disappearance of Jimmy Hoffa is one that continues to fascinate. Hoffa's disappearance in 1975 remains one of the most high profile alleged mafia hits of the 20th century, and easily the biggest cold case in America. Hoffa was the president of the International Brotherhood of Teamsters labor union for nearly 15 years, and he's believed to have multiple connections to organized crime, and on July 30, 1975, Hoffa was on his way to meet with New Jersey Mafia boss Anthony Provenzano at Machus Red Fox, a restaurant in Michigan.

Hoffa disappeared sometime after arriving in Michigan, and there are a ton of theories about what happened to him. Some people believe he was abducted by federal agents, others believe he was thrown out of an airplane, and others have theorized that he's buried in a swimming pool somewhere. The most likely theory is that Hoffa is buried in a steel drum somewhere in a landfill in New Jersey. The FBI began surveying the site in 2021 but has yet to release their findings.
