For six unforgettable seasons, the charismatic actor Bob Crane lit up our screens as Colonel Robert Hogan in the classic comedy Hogan’s Heroes. Playing the role of a clever American serviceman leading a group of Allied prisoners during World War II, Bob’s charm and wit made him a household name. Week after week, audiences tuned in to watch his team of POWs outsmart their clueless German captors with daring acts of espionage and sabotage.

However, the story took a chilling turn in 1978. While Hogan’s Heroes continued to thrive in syndication, tragedy struck in Scottsdale, Arizona. Bob, who had been performing in a dinner theater production, was found brutally murdered in his bed. The crime scene was anything but ideal for investigation—contaminated with fingerprints, footprints, and hair samples. Bob’s eldest son, Robert, recalls the harrowing experience of visiting the crime scene alongside his father’s attorney and business manager. “It was a scene of chaos,” he says, “and unfortunately, the investigation didn’t receive the attention it deserved.”

As details of the case unfolded, the public learned of another side of Bob Crane. Today, what might be labeled as sex addiction was a significant part of his personal life. He had a history of infidelity, involving numerous women, and often documented these encounters with the help of his close friend, John Henry Carpenter, an expert in home video equipment. This aspect of Bob’s life painted a complex picture of a man who struggled with balancing his public persona and private desires.

Despite being known as a happy-go-lucky guy, Bob’s personal life had its darker moments. His addiction caused significant upheaval, including the dissolution of his 21-year marriage to Anne, the mother of his son Robert. He remarried Patricia, an actress known professionally as Sigrid Valdis, whom he met on the set of Hogan’s Heroes. Patricia was just one of several women Bob pursued during his time on the show, further complicating his personal relationships.

Bob’s career also suffered due to his personal choices. During the filming of the family-friendly movie Superdad in 1973, co-starring a young Kurt Russell, Bob shared explicit photos with crew members. This behavior caught the attention of executives at Walt Disney Productions, who were understandably upset. “News travels fast in this business,” Robert explains, “and soon it was all over publications like the National Enquirer. It was a tough pill for Dad to swallow.”

Reevaluating His Choices: Bob Crane's Journey Toward Change

As Bob approached his 50th birthday, he began reflecting on his life and decided it was time for a fresh start. He confided in his son about his plans to divorce Patricia and distance himself from Carpenter. “He wanted to turn over a new leaf,” Robert recalls. Tragically, Bob’s life was cut short just weeks before his milestone birthday.

In 1992, Carpenter found himself on trial for the murder of Bob Crane. Prosecutors argued that since there was no sign of forced entry into Bob’s apartment, the killer must have been someone Bob knew. They suggested Carpenter was upset about the end of their friendship and, in a fit of rage, bludgeoned Bob to death with a camera tripod. Blood traces matching Bob’s type B blood were also discovered on the door of Carpenter’s rental car, further complicating the case.

Despite the circumstantial evidence, the jury acquitted Carpenter in 1996. Diana, Carpenter’s wife of 42 years, stood by her husband, stating, “He made some poor decisions in life, but I truly believe he didn’t kill Bob Crane. John was a good man, contrary to what some might think.”

Years later, in 2016, new tests were conducted on the crime scene samples. These revealed the presence of another unidentified male, yet no new suspects emerged. To this day, the identity of Bob Crane’s killer remains a mystery.
