Over the years, we've lost many beloved stars in unusual ways. In some cases, the cause of death just doesn't add up and even experts can't determine precisely what happened. For those stars, the loss of life becomes that much more tragic.
In this gallery, we're looking back at celebrity deaths that have long been plagued by mystery. Click through the gallery for a closer look at 10 cases — starting with actor Bob Crane.
Bob Crane has one of the most mysterious and troubling deaths in Hollywood. The Hogan's Heroes actor died in 1978 when he was found bludgeoned to death at age 49. The death, which occurred while Crane was acting on a theatre tour, remains unsolved today.
The classic TV star's reputation was reconsidered after he died, as the public learned of his involvement with pornography and sex films — a secret lifestyle that may have had a role in how he died. A friend of Crane's once stood trial for the violent death, but he was acquitted. The unsolved case was also examined in the film Auto Focus.
