The Keddie Cabin Murders Were Not Baffling. They Were Mishandled.
How a viable suspect, a near-confession, a recorded tip, and a letter that reads like a murder admission were all allowed to evaporate before anyone was charged.
- Three people were murdered in Cabin 28 of the Keddie Resort on the night of April 11, 1981. A fourth victim, a 12-year-old girl, was taken from the scene and her remains were not recovered for three years. No one has ever been charged.
- The primary suspects, Martin Smartt and his friend John “Bo” Boubede, were questioned and allowed to leave Plumas County within days of the murders. Both died without being charged.
- Smartt allegedly confessed to a VA counselor weeks after the murders. The California Department of Justice was informed and dismissed the information as hearsay. It was not pursued.
- A letter Smartt wrote to his wife after leaving town contains language investigators have characterized as a near-confession. It was “overlooked” during the original investigation and never admitted as evidence.
- A tape recording of an anonymous caller providing specific information about the location of Tina Sharp’s remains was never admitted into evidence and was later found at the bottom of a storage box.
- The DOJ, when called in to assist, sent agents from its organized crime unit rather than homicide. That decision is understood to be connected to Boubede’s alleged organized crime ties, which meant the department’s response to a quadruple homicide was shaped around protecting an asset rather than solving the murders.
In April 1981, four people were murdered in a cabin in a small, isolated resort community in the mountains of Northern California. The victims were bound, bludgeoned, and stabbed. A 12-year-old girl was taken from the scene. Three younger children were found unharmed in a back bedroom the next morning. No forced entry. No arrests. No charges. Ever.
Over four decades of true crime retelling, the Keddie Cabin murders have been dressed in the language of impossibility. How did someone kill three people in a small cabin without the children in the next room waking up? How did a killer vanish from a remote mountain community with a single road in and out? How was a 12-year-old girl taken and not found for three years?
The framing is always the same: eerie, inexplicable, uniquely baffling. The reality is different. The case produced viable suspects within days of the murders. Those suspects were allowed to leave the county. One of them may have confessed to a counselor weeks afterward. One wrote a letter to his wife that investigators have spent years trying to get admitted as evidence. A tip that led to the recovery of a missing child’s remains was recorded, buried in a box, and forgotten.
The Keddie Cabin murders were not baffling. They were investigated poorly at moments that could not be recovered. Rita ruins it.
When Sheila Sharp arrived home on the morning of April 12, 1981, to change clothes before church, she found her mother, her brother, and his friend dead inside Cabin 28. She had spent the night next door with neighbors. The three younger children — Rick, Greg, and their friend Justin Smartt — were removed from a rear bedroom window by Sheila and a neighbor before police arrived.
The Plumas County Sheriff’s Office called in the California Department of Justice. This decision, made immediately, shaped the entire trajectory of the investigation in ways that would not be understood for decades. The DOJ sent two special agents from its organized crime unit. Not homicide. Organized crime.
The decision to dispatch organized crime agents rather than homicide investigators only makes sense in context: John “Bo” Boubede, one of the primary suspects, had alleged ties to organized crime in Chicago. He operated under at least two known aliases. The DOJ apparently treated Boubede’s presence as the operative fact, which meant the department’s approach to a quadruple homicide of a single mother and two teenagers was filtered through the lens of its own interests in Boubede rather than through the lens of solving the murders.
Special investigator Mike Gamberg later stated that both the DOJ and local deputies made “crucial mistakes” in the original investigation and that some individuals with the experience to properly work the scene and follow the leads were not allowed to do their jobs.
Martin Smartt, a neighbor who lived in Cabin 26 with his wife Marilyn and stepson Justin, quickly surfaced as a person of interest. He told investigators early on that a hammer of his had recently gone missing. He and Boubede both left Plumas County within days of the murders. Both were questioned. Neither was held. Both passed polygraph tests during the original investigation, which investigators later characterized as a procedural anchor that gave the early investigation reason not to push harder.
The FBI was briefly involved due to the presumed abduction of Tina Sharp but withdrew within weeks, deferring to the DOJ on the grounds that the state agency was doing adequate work. It was not.
The public narrative around the Keddie Cabin murders rests heavily on perceived impossibility: three people murdered quietly enough that children in the next room did not wake. But this is not impossible. It is, in fact, the expected pattern in multi-victim crimes where the attacker maintains control through speed, surprise, binding, and physical dominance. The victims were tied with rope and medical tape before they were killed. The binding was the mechanism of control, not the chaos of a struggle.
The medical tape used to bind the victims almost certainly came with the perpetrators. It was not a household item from the cabin. The attack was prepared. Someone brought supplies. That is not the profile of a random opportunistic assault. It is the profile of a targeted act by someone who expected to be there and planned to control the scene.
Confirmed: The victims were bound before they were killed. Medical tape was brought to the scene. The attack was planned, not spontaneous.
Confirmed: Martin Smartt reported a hammer missing shortly after the murders. That hammer was recovered from a pond near the crime scene in 2016.
Confirmed: Smartt wrote a letter to his wife after leaving the county that included the line: “I’ve paid the price of your love and now I’ve bought it with four people’s lives.” This letter was “overlooked” during the original investigation and was never admitted as evidence.
Confirmed: An anonymous caller contacted authorities in 1984 and directed them toward the location of Tina Sharp’s remains. The tape of that call was not admitted into evidence and was later found at the bottom of a storage box in the department.
Confirmed: A VA counselor reported in 2016 that Smartt had confessed to killing Sue and Tina Sharp during a session weeks after the murders. The DOJ was informed of this in 1981 and dismissed it as hearsay.
Confirmed: DNA recovered from crime scene tape was linked to a living, unidentified suspect in 2018.
Unestablished: The identity of all individuals present in the cabin that night. Investigators believe as many as six people may have been involved in the murders or the cover-up, and that at least two living individuals have knowledge as accessories after the fact.
On the Surviving Children
A persistent element of the mystery framing is the question of how three children survived in a back bedroom while three people were murdered in the adjacent room. The answer is the same answer that applies to most multi-victim crimes: the perpetrators prioritized their targets. The children were not killed. That is not a riddle requiring symbolic or ritualistic explanation. It reflects a decision made by whoever was in that cabin about who they had come for and who they had not. Leaving witnesses is a risk, but it is a risk offenders take regularly when the alternative is an escalating body count that increases exposure.
Justin Smartt, one of the surviving children and the stepson of Martin Smartt, later said he saw two men in the cabin that night. One had a mustache and long hair. The other was clean-shaven with short hair. Both wore gold-framed glasses. Composite sketches were released. Nothing came of them in the original investigation.
“We found evidence that was never brought forward by the officers and department of justice.” — Plumas County Special Investigator Mike Gamberg
Small-Town Proximity
Keddie in 1981 was a former resort community converted to low-income housing, with one road in and out, a population small enough that everyone knew everyone, and a social ecosystem in which law enforcement, suspects, and witnesses occupied the same daily geography. Martin Smartt’s stepson was one of the surviving children. Smartt’s wife had been friendly with Sue Sharp. A neighbor helped remove the children from the cabin window before police arrived.
Social proximity does not require corruption to create drag in an investigation. It only requires hesitation, deference, and a reluctance to aggressively pursue someone embedded in the same community. There is credible reporting suggesting the level of drag in this case exceeded hesitation: Sheila Sharp, the surviving daughter who discovered the bodies, has stated that she was told suspects were told to leave town. Special investigator Gamberg has characterized some evidence as having been deliberately buried.
The Organized Crime Complication
Boubede’s alleged organized crime connections introduced a layer of institutional interest that appears to have diverted investigative energy away from the homicides themselves. DOJ’s decision to send organized crime agents rather than homicide investigators is not explained by the facts of the murder. It is explained by Boubede’s background. When the interests of a law enforcement agency in its own sources and investigations run parallel to a homicide case, the homicide investigation frequently loses. That appears to be what happened here.
The Evidence That Was Not Pursued
The VA counselor’s report of Smartt’s alleged confession came in May 1981, weeks after the murders, while Smartt was still alive and locatable. The DOJ dismissed it as hearsay. Under California law, therapist-patient privilege does not protect confessions of murder: the Tarasoff duty and its statutory descendants require disclosure when a patient reveals past or ongoing serious crimes. Whether that legal framework was properly applied or simply bypassed is not established by the public record. What is established is the result: the information was dismissed and not pursued, Smartt was never confronted with it, and he died in 2006 without being charged.
The letter to Marilyn was “overlooked.” The tape recording of the anonymous caller was filed and forgotten. The hammer Smartt reported missing sat in a pond near the scene for 35 years before a tip from a Boubede family member led investigators to it in 2016.
This is not a case where evidence did not exist. Evidence existed at multiple points. It was not collected, not pursued, not admitted, or not found until the people most responsible for the murders were dead.
The Keddie Cabin murders became a recurring fixture in true crime media over the decades. The case has been covered by BuzzFeed Unsolved, ABC10’s Unsolved California series, numerous podcasts, and documentary productions. The 2017 film Cabin 28 took the murders as its direct inspiration, translating a case defined by institutional failure into a stylized home-invasion narrative that emphasized atmosphere and brutality while flattening every procedural dimension of the story.
The pattern is consistent across adaptations: the violence is amplified, the isolation is aestheticized, and the investigative failures become background texture rather than the central analytical problem. The case gets reframed as horror rather than accountability failure. Once that translation happens, the unanswered questions become features of the genre rather than indictments of an institution.
Myth always thrives where institutions falter. The longer a case remains open without a charge, the more it becomes content instead of investigation, and the more the victims become archetypes rather than people.
Sue Sharp was 36 years old. She had moved her five children to Keddie after separating from her husband, looking for a fresh start in a larger place than the trailer they had been living in. She had taken a typing class. She had a part-time job at the local Elks Lodge. She was apparently the kind of person who sat with a neighbor’s wife who was being abused and helped her think through how to leave. Three of her children survived. Two of the murdered victims were teenagers who happened to be in the wrong cabin.
Sheila Sharp was 14 years old when she came home to find her mother and brother dead. She has spoken publicly about the case for decades. She has said she believed there was a cover-up. She has said she carries the hope that the case will be solved, that it was reactivated with the 2016 hammer recovery and the 2018 DNA results, and that she has had to manage cycles of renewed hope and continued absence of resolution.
Tina Sharp was 12 years old. Her cause of death was never determined. Her remains were found near Feather Falls three years after she disappeared, identified by dental records. She died no earlier than six months after the murders, which means whatever happened to her after she was taken from Cabin 28, she did not die that night. That detail is in the record. It has no comfortable place in the mystery narrative.
When a case like this goes unresolved, the cost is not just unsolved status. It is permanent erosion of certainty for the people who survived it. The chain of custody becomes questionable, defense leverage grows, prosecutors hesitate, and families are asked to carry an open wound indefinitely while the case cycles through documentary series and podcast seasons. That is not justice. It is institutional failure dressed as mystery.
The Keddie Cabin murders are not unsolved because the crime was impossible to understand. They are unsolved because the investigation failed at consecutive critical junctures, and by the time those failures were identified and addressed, the primary suspects had died.
Martin Smartt allegedly confessed to a counselor in May 1981. That information was dismissed. He wrote a letter to his wife that investigators have spent years trying to get admitted as evidence. That letter was overlooked for decades. He reported a hammer missing and it sat in a pond near the crime scene for 35 years. An anonymous caller directed authorities to the location of a missing child’s remains and the tape was found at the bottom of a box.
None of this is mystery. All of it is failure. The case required basic investigative discipline: pursue the confession report, admit the letter, recover the hammer, process the tip tape. What it got instead was organized crime agents dispatched to cover a quadruple homicide, a social environment that discouraged aggressive pursuit of local suspects, and institutional inertia that lasted long enough for the most culpable individuals to age out of accountability.
The 2018 DNA result indicates at least one living person was present in that cabin. The investigation continues. Whether it produces a charge will depend on whether the institutional will that was absent in 1981 can be sustained long enough to see it through. The victims’ family has been waiting 44 years. The case is not cold. It is unfinished.
Rita ruins it anyway.
