Keddie Cabin Murders: Unsolved California Crime That Remains a Mystery
The Keddie Cabin Murders in scenic Plumas County, California, have haunted residents and true crime enthusiasts for over four decades.
On April 11, 1981, Cabin 28 turned from a vacation retreat into a macabre crime scene. Sheila Sharp, returning from a friend’s house, discovered the mutilated bodies of her mother, Sue, her brother John, and John’s friend Dana Wingate. The horrifying reality that these were not mere accidents but homicides struck the community hard.
Sue Sharp, the matriarch, moved her family to Keddie seeking a fresh start. A devoted mother, she aimed to provide a better life for her five children.
On that fateful night, the tranquil resort failed to shield them from the coming terror. The scene Sheila walked into could only be described as harrowing: bloodstains marred the walls, and the victims were bound with medical and electrical tape.
The brutality did not end there.
Tina Sharp, Sue’s 12-year-old daughter, was missing. Her disappearance added another layer of dread.
The community’s initial shock turned into frustration as the investigation dragged on without solid leads. Law enforcement scoured for clues but found little that pointed directly to the killers. Fragments of a knife, a bent but unexplained hammer, and Sue’s broken glasses were critical yet perplexing pieces of evidence.
Local law enforcement, despite their efforts, couldn’t break the case. Even with involvement from the FBI, the puzzle of Cabin 28 remained unsolved.
The suspects, musicians and townsfolk alike, were interrogated yet no conclusive evidence emerged.
The case’s complexity deepened when remnants of Tina’s skull were discovered three years later in a forest 50 miles away. This discovery intensified media coverage and public intrigue but did little to solve the mystery.
The emotional toll on the Sharp family and the community was immense. Residents grappled with fear and suspicion, worried the perpetrators were among them. Societal analyses suggested the heinous crime exposed darker, unfathomed undercurrents of their seemingly idyllic life.

Why Do the Murders Remain Unsolved?
The Keddie Cabin Murders baffle many due to one key question: why do they remain unsolved?
Despite extensive efforts, the case has endured decades without resolution, fueling endless speculation.
Lack of Evidence and New DNA Evidence
Insufficient physical evidence posed a major challenge for investigators. The crime scene at Cabin 28 was contaminated, complicating efforts to gather concrete clues.
Witnesses were scarce, leaving authorities grasping at straws. Imagine a town gripped by fear, with residents eager for answers yet helpless in providing them.
In 2013, hope briefly ignited when new DNA evidence surfaced. Although this breakthrough seemed promising, it led nowhere. The DNA, still unmatched, left investigators frustrated.
Role of County Sheriff
The Plumas County Sheriff’s Office faced harsh criticism for mishandling the case.
Initial responders failed to secure the scene, allowing contamination. Key leads were overlooked, and crucial evidence likely slipped through the cracks. Under Sheriff Doug Thomas, investigative missteps left many wondering about potential missed opportunities.
You’d think a high-profile case like this would receive utmost care, yet the truth is, procedural mistakes hampered progress. Missteps like these eroded trust within the community.
Suspects and Their Alibis
Over the years, several suspects emerged, including Martin Smartt and John “Bo” Boubede.
Despite suspicions, each suspect had seemingly credible alibis. Smartt, a known figure in Keddie, claimed he was with Boubede all night. You might think that repeated questioning would break someone, but in this case, reliable stories prevailed.
The police couldn’t crack their alibis, and with limited evidence, no charges held. The suspects walked free, leaving a trail of unanswered questions behind them.
These factors combined to keep the mystery alive, perpetuating a cloud of uncertainty over Keddie, California.

Marty was known for his volatile relationship with Marilyn, leading to frequent domestic disputes. This turbulent relationship raised suspicions when the murders occurred.
Marty reportedly confessed to a therapist, saying he had even confessed to Marilyn, who later recanted her statement. Investigators found Marty’s erratic behavior suspicious, yet they never gathered enough evidence to charge him.
