Bob Crane’s Kinky Murder — Son Accuses Celebrity Stepmom

Kinky “Hogan’s Heroes” star Bob Crane was murdered by his second wife! That’s the shocking claim by the actor’s son — who fingered his stepmother, "Hogan Heroes" actress Patricia Olson, during a bombshell world exclusive interview with The National ENQUIRER. [GRAPHIC PHOTOS FOLLOW...]

“She was the only one who stood to gain anything from my dad’s death!” said Robert Crane Jr., of the still-unsolved crime. “She inherited everything!” The sitcom star was 49 when he was savagely bludgeoned to death in a sleazy Scottsdale, Ariz., apartment on June 29, 1978.

An electrical cord was tied around his neck in what police described the grisly surroundings as “a passionate crime scene.” The prime suspect was Bob’s bisexual pal, John Henry Carpenter, whom the actor was set to ditch after years of cavorting in orgies together!

Carpenter was charged with murder in 1992, but was acquitted. Robert Jr. still remains convinced his stepmother (seen here with Crane and costar Robert Clary) killed his father!

Olson had played Bob’s love interest, Hilda, on the show under the stage name Sigrid Valdis. But they were headed for a bitter split, according to Robert Jr.!

Sadly, the charges made by Bob's bitter son will go uncontested, with Olson having died in 2007. She's buried beside Bob in Los Angeles — and she isn't the only suspect besides Carpenter in Crane's sordid death!

Sources also came to The ENQUIRER saying that the actor — who was obsessed with shooting private X-rated videos of his raunchy romps — was slain by a mob boss!

The insiders said that notorious criminal Dominic Brooklier had Crane whacked after the star backed out from making a porn film! Bob's son, however, still blames his wickedly sexy stepmother. “This was CLEARLY a murder of passion,” he said. “There were vicious blows to the head. She would have the passion to do that!”
