Despite forensic evidence and viable suspects, the case remained unsolved due to a combination of factors, including a lack of DNA evidence, poor handling of the investigation by the Plumas County Sheriff's Office, and the disappearance of a key witness, Tina Sharp. The investigation was also criticized for not following up on leads and ignoring critical forensic evidence.
The Sharp family moved to Keddie, California, in July 1979 after Sue Sharp divorced her abusive husband, James Sharp. She wanted to start a new life away from him and closer to her brother, Don Davis, who lived in California.
The police failed to realize that Tina Sharp was missing for several hours into the investigation, which was later criticized as a significant mistake. This delay gave potential abductors a head start, complicating efforts to find her.
Key forensic evidence included a bent steak knife, a butcher knife, a claw hammer, and blood spatter patterns. The walls had bloody stab marks, and an unknown fingerprint was found in the blood. The phone cord was cut, and the lights and drapes were turned off, suggesting the killers tried to cover their tracks.
Justin Smart gave conflicting stories about the night of the murders, initially claiming he was asleep and heard nothing, then saying he dreamed about the murders, and later stating he witnessed them. Under hypnosis, he described two men who entered the cabin, leading to a fight and Tina being taken away.
The police suspected multiple people were involved due to the brutal nature of the attacks and the strength of the victims, particularly the two teenage boys, John and Dana. It was considered unlikely that a single person could overpower and kill all three victims without a struggle.
Neighbors reported hearing muffled screams from the cabin at around 1:30 AM, but the boys inside the cabin claimed they slept through the entire night and heard nothing. This discrepancy raised questions about the boys' accounts and the timeline of the murders.
The Plumas County Sheriff's Office faced criticism for several reasons, including failing to realize Tina Sharp was missing, not following up on leads, ignoring critical forensic evidence, and not enlisting the help of qualified forensic experts. The investigation was described as poorly managed and lacking in thoroughness.
The discovery of Tina Sharp's remains exactly three years after the murders raised suspicions about whether someone knew more about the case. The timing was seen as potentially significant, leading to questions about the motives and actions of those involved.
Sue Sharp was the only victim partially covered with a blanket, possibly because she was visible through the bedroom door and the killer wanted to hide her from the other children. Another theory suggests this was done out of respect or to avoid looking at her during the murder.
#257 - Part 1: One night in April 1981, a grisly quadruple murder took place in the small northern California town of Keddie. To this very day, the case remains unsolved. But that doesn’t mean there isn’t any forensic evidence or suspects.
