While staying at a downtown Los Angeles hotel in 2013, 21-year-old college student Elisa Lam disappeared, with the only clue as to what happened being some security camera footage of her acting very strangely in an elevator on the night of her disappearance. She was found nearly three weeks later in a water tank on the hotel's roof, but how she got there — and why — remains a mystery.

Rodney Alcala was convicted of murdering five people between 1977 and 1979, and later was convicted of killing two more. However, many believe it's possible that number should be even higher, with investigators finding over 1,000 photos he took of many more women in his home. But the most bizarre part of his tale is that — at the height of his killing spree — Alcala appeared as a contestant on The Dating Game... and won.

In one of the most notorious heists in history, an unknown man — who has since been dubbed "D.B.

In 2004, the third wife of police officer Drew Peterson — Kathleen Savio — was found dead in an empty bathtub, covered in bruises with stab wound on her head. However, the autopsy ruled her death an accidental drowning. Three years later, the fourth wife of Peterson, Stacy Ann Peterson, disappeared, and this time Peterson came under the eye of investigators. It was alleged that the original autopsy of Savio was a coverup by some of Peterson's friends in the police department, and he was convicted for killing her. Stacy, however, has never been found, and Peterson has never been charged in her case.

Already turned into a movie starring Jack Black, the case of convicted killer Bernie Tiede got even stranger after the film's release.
