Five months later, the Sharps had found a semblance of community in their new home, with the children having made friends amongst the other residents of the Keddie cabins. On the night of the murders, Sue was at home while her two youngest sons, Rick and Greg, and their friend Justin Smartt played in an adjacent room. Tina, Sue’s youngest daughter, returned home around 10 o’clock, after an evening of watching television with the neighbors in Cabin 27. Sue’s oldest son John had spent the day in the town of Quincy with his friend Dana Wingate. The pair was last seen walking along State Route 70. They returned home to Cabin 28 later that night, presumably retiring to John’s basement bedroom. Whether they entered the home with the murders actively in progress or became aware of intruders after hearing a disturbance upstairs is unknown. In either case, John and Dana would not survive the night.

Upon entering, she discovered three bodies on the living room floor of Cabin 28. Sue, John, and Dana's bodies had been left, sprawled across the floor. A search of the premises revealed the trio of younger boys still in their room, alive and unharmed. With the help of neighbors, Sheila removed the three children. The final member of the Sharp family, 12-year-old daughter Tina, was nowhere to be found.

The three victims found in the cabin had met a violent end. Their bodies were bound with medical tape and appliance wire; they had been stabbed, bludgeoned, and strangled to death. Examinations revealed that the victims suffered blows from at least two different hammers of varying sizes, and Sue and John had been stabbed repeatedly. Sue had also been bludgeoned with a Daisy Powerline 880 rifle, while Dana Wingate was strangled to death by hand. Sue was discovered lying on her side by the living room couch and was nude from the waist down. She had also been gagged with a blue bandana and her own panties—they had been secured on her face with medical tape. Her wrists and ankles were also bound with medical tape and two rounds of electrical wire. There was also wire that tied her ankles together—her ankles and wrists were tied so tightly that her legs and knees were drawn toward each other. She had been covered with a blanket and sheet that belonged to Tina. Johnny’s hands were placed on his abdomen and taped tightly at the wrists with medical tape. His ankles were wrapped twice and tightly knotted with an extension cord. Dana had also been bound with medical tape.

Detectives also discovered that the telephone had been left off the hook and the lights had been shut off with all the drapes fully closed. Various weapons were found at the scene, including a table knife, a butcher knife, and a bloody hammer. Other weapons—including the Daisy rifle—were not recovered. Some evidence, such as a second bloody knife, turned up in a trash bin behind the Keddie general store. In interviews, Justin Smartt told detectives that he had dreamt details of the murder only to later confirm that he had actually witnessed it. Under hypnosis, Justin claimed that he had seen Sue with two men: one with a mustache and long hair and one clean-shaven with short hair. John and Dana then entered the home and began arguing with the men. The argument became violent. The three were still alive when Tina entered the room. One of the men took her out the back door, before coming back to kill Sue, John, and Dana.

Composite sketches (above) were made based on Justin's descriptions, but never led to any identification. In April of 1984, three years after the slayings occurred, part of a skull was found 29 miles away near Camp Eighteen in neighboring Butte County. The discovery prompted a thorough examination of the area, revealing a jawbone and several other bones. The fragments were eventually determined to belong to young Tina. The discovery of Tina’s remains compounded a case already steeped in mystery. Why was the body of Tina Sharp found so far away from Cabin 28? How could a murder with so much physical evidence remain unsolved? The abundance of loose threads, in conjunction with what appeared to be a substandard investigation, have prompted some to suspect a police cover-up.

Some theorists believe that mob, gang, or police connections were responsible for the bungling of the case and the destruction of the property–but without the complete facts, it's hard to know whether incompetence, conspiracy, or mere bad luck have left the Keddie murders unsolved.

In 2008, Marilyn Smartt (mother of Justin) claimed in a documentary on the murders that she suspected her husband Martin Smartt and his friend Bo Boubede were responsible for the murders of Sue, John, Dana, and Tina. In the same documentary, Sheriff Doug Thomas stated that Martin had successfully passed a polygraph examination about the murders–of course, the use of polygraphs in criminal cases has become increasingly discounted in recent years. It was later confirmed that Martin was close with the Sheriff of Plumas County despite the fact that both Martin and Bo had criminal records.

Several new pieces of evidence and information came to light, which may finally help crack this cold case. First, though the primary suspects in the slayings, Marty Smartt and Bo Boubede, are now deceased, new details continue to emerge that suggest their culpability. According to People magazine , Smartt's anger toward Sue Sharp for interfering in his marriage was a viable motive for the killings. After the murders, he wrote a letter to his wife Marilyn, which was only discovered after the case was reopened in 2013: “I’ve paid the price of your love & now that I’ve bought it with four peoples lives, you tell me we are through … Great! What else do you want?” Though Marilyn claims she never received the letter and was only made aware of it after the murders by the authorities, she confirmed that it was in Smartt’s handwriting. Even more potentially incriminating is a therapist in Reno, Nevada, to whom Smartt allegedly confessed the murders.
