The three boys—Rick and Greg Sharp, and their neighbor Justin Smart—were found unharmed in one of the bedrooms. One theory suggests that Marty Smart, Justin's stepfather, was involved in the murders and spared the boys because one of them was his own son.
Three murder weapons—a bent steak knife, a bloody butcher knife, and a claw hammer—were found inside the cabin. Blood evidence suggested the victims were moved or staged before the killers left, but no DNA from the killers was initially identified.
Despite Marty Smart's suspicious behavior and statements, the Plumas County Sheriff's Department let him go after one interview and did not consider him a suspect. Some speculate this was due to the then-sheriff Doug Thomas's personal friendship with Marty.
The anonymous caller suggested the remains might belong to Tina Sharp, who had gone missing three years prior. This is significant because the caller knew about the remains before they were publicly identified, raising suspicions about their involvement.
DNA was found on a strip of white medical tape used to bind the victims. This DNA matches that of a known living suspect, which could be a key to solving the case. However, the identity of the suspect has not been disclosed.
The most widely accepted theory involves a love triangle between Marty Smart, Marilyn Smart, and Sue Sharp. Marty and Sue were allegedly having an affair, and Sue was counseling Marilyn to leave Marty. This led Marty to enlist his friend Bo Bobadie to kill Sue and the others.
The hammer found at the bottom of the pond matches the description of the one missing from Marty Smart's garage. Its intentional placement suggests it was hidden there to avoid detection, potentially linking it to the murders.
There is a $5,000 reward for information leading to the arrest of the killer or killers. Tips can be submitted to the Plumas County Sheriff's Office at 530-283-6360.
The case faces challenges due to mishandled forensic evidence, lack of credible leads, and the death of primary suspects. Despite new forensic evidence and ongoing investigations, the case remains unsolved, with the identity of the DNA match on the tape still unknown.
#258 - Part 2: 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.
