Who killed Hogan's Hero?

"Bob" Robert Edward

Crane

He was an American actor, drummer, radio host, and disc jockey known particularly for starring in the CBS sitcom Hogan's Heroes.

He was born July 13th, 1928, in Waterbury, Connecticut.

He was a drummer from age 11.

His first major role was on the Donna Reed show.

June 1978, Crane was living in the Winfield Place Apartments in Scottsdale, Arizona.
June 29, Crane's co-star Victoria Ann Berry, entered his apartment after he failed to show up for a lunch meeting.
That is when she discovered Crane.
He had been bludgeoned to death with a weapon that was never identified.
Investigators believed it to be a camera tripod.
An electrical cord had been tied around his neck.

Crane and John Henry Carpenter supposedly filmed themselves having sex with women.

Crane had a extensive collection of this in his home, which led the police to Carpenter.

Carpenter's rental car was impounded and searched.

Blood smears were found that matched Crane's blood type.

In 1990, Scottsdale Detective Jim Raines, re-examined the evidence from 1978 and persudaded the county attorney to reopen the case.

Raines discovered an evidence photograph of the car's interior that appeared to show a piece of brain tissue.

Even though the actual sample was lost, an Arizona judge said it was admissible.

June 1992, Carpenter was arrested and charged with Crane's murder.

During the 1994 trial, Crane's son Robert, testified that in the weeks before his father's death, Crane had repeatedly expressed a desire to sever his friendship with Carpenter.

Carpenter was acquitted and still maintains his innocence. 

After the trial, Robert Crane speculated publicly that Crane's widow, Patricia Olson, might have had a role in instigating the crime..
He alluded to his dad's will, which excluded him, his siblings, and his mother, and left the entire estate to Olson.

Maricopa County District Attorney Rick Romley, who prosecuted the case, is convinced that John Carpenter killed Crane.

Some people suggest that the women in the videos Crane and Carpenter "collected" might have not been too happy and had Crane killed.

The case remains unsolved.
