'Hogan's Heroes' Star Bob Crane's Murderer to Be Revealed on Live TV

The man who viciously murdered Bob Crane, the star of the iconic TV show "Hogan's Heroes," may be exposed on TV after a 38 year unsolved mystery.

Crane was bludgeoned to death with a camera tripod in his Scottsdale apartment back in 1978. He and his good friend, John Carpenter, were deep into kinky sex ... secretly filming various sexual configurations involving numerous women.

Carpenter's rent-a-car was seized by cops just days after Crane's murder, and they found blood inside. Carpenter was tried for murder, but there was a problem. DNA was not perfected then, and the jury found him not guilty because there wasn't conclusive proof it was Crane's blood.

Enter Phoenix Fox 10 anchor John Hook. More than a year ago, Hook started working with the Maricopa County Attorney's Office and convinced prosecutors to release enough blood so state-of-the-art DNA tests could be conducted.

The DNA results are in. Hook is mum, but he will reveal the results Monday on the 9 PM news.

If the blood is a match with the blood found in Carpenter's car, it's close to a slam dunk he was the killer, but he can't be prosecuted for 2 reasons ... double jeopardy, and he's dead.
