On the chilling afternoon of June 29, 1978, the almost-50-year-old Hogan's Heroes star was discovered bludgeoned to death. He had a ligature tied around his neck, which a medical examiner later suggested was used to strangle him.

Crane's autopsy report indicated that he died as a result of blunt force impact to his head, but renowned forensic pathologist Dr. Michael Hunter believes the series of events that led up to the actor's cold killing is perhaps even darker than the murder itself.

"Going through hundreds of statements to the police, I have discovered that Bob Crane was addicted to sex and documenting his sexual conquests with photographs and the new medium of home video," Hunter says, noting that the behavior "caused both of his marriages to collapse and his career to nosedive."

"I think it's highly likely that Bob's addiction to sex and pornography also played a role in his murder," he hypothesized.

Some experts have linked Crane's brutal divorce battle to the tragic incident, while others thought the Mob might have been involved. But everyone has always seemed to agree on one thing – that the actor's addiction to sex, [expletive] and filming himself in the act played a significant role in his ultimate demise.

Following his death, police found Crane's apartment full of home video cameras, lights and editing equipment. They assumed that one of his tripods was the murder weapon.

Soon, they turned their attention to a home video equipment salesman, who had introduced the actor to the then-new technology. He was even featured in several of Bob's sex tapes.
