Keddie, a quiet and peaceful resort town of log cabins, was the site of a horrific quadruple homicide in 1981. On the night of April 11, 14-year-old Sheila Sharpe had gone to a neighbor’s house to spend the night. When she came home in the morning, she found that her mother, Sue, her brother Johnny and his friend Dana had all been tied up and stabbed to death. Her younger sister, Tina, was missing, yet her younger brothers, Ricky and Greg, and their friend Justin were unharmed in the brothers’ bedroom.
The police were at a loss to uncover a killer or a motive. The murder victims had been relentlessly tortured. Sue and Johnny had been struck with a hammer, and Dana had been strangled. The stabbing had been so violent that the blade of the murder weapon, a steak knife, was bent backward.
Incredibly, Ricky and Greg said that they had slept through the attack. But Justin changed his story several times. In one of his accounts, he said that he witnessed the murders and Tina being taken. In other statements, he claimed to have dreamed the incidents he described.
In 1984, Tina’s skull was found 50 kilometers (30 mi) away from Keddie. Her cause of death could not be determined, but it seemed that she had died the night of the attack. Meanwhile, the search for the murderer was at a standstill. There were still no suspects, although Justin’s father, Martin Smartt, and his friend Bo Boubede acted strangely when they were interviewed by police.
Smartt even described how the murders might have been carried out yet was never pressed further. Years after the murders, his therapist claimed that Smartt once said that he had killed Sue because she encouraged his wife to divorce him. He supposedly killed Tina, too, but denied killing Johnny and Dana. Both Smartt and Boubede are long dead, however, and the case remains officially unsolved.

On November 12, 2008, a couple near the northern California city of Eureka found 23-year-old Christine Walters naked and bleeding on their doorstep. They took the incomprehensible young woman to a hospital, where she refused to explain what had happened to her. After she was discharged, Walters told her mother in Wisconsin that she had been chased by demons through a forest after she participated in a shamanic ritual. Her mother offered to fly to California to get her, but Walters insisted that she would fly back to Wisconsin by herself.
According to her mother, Walters acted paranoid on the phone over the next few days. She believed that the forest demons were trying to hunt her down. She couldn’t say why she was bleeding and naked that day because the demons would hear her. On November 14, Walters left her ID and backpack at a coffee shop and walked out. She was never seen again.
Walters had been staying on the West Coast for the four months preceding her disappearance. She had fallen in love with northern California’s natural beauty and alternative lifestyle scene. According to friends and family back home, she had met a group of like-minded spiritualists. Walters was a trusting person, and it’s possible that she might have become involved with a dangerous crowd among the alternative community.

In the early hours of August 30, 2013, 19-year-old college student Bryce Laspisa was driving home from northern California when he called his parents and told them that he was going to pull over and sleep. Bryce, who had been visiting his girlfriend, never returned home that morning. Around 8:00 AM, an officer from the California Highway Patrol showed up at the Laspisas’ home in Laguna Niguel to tell them that Bryce’s crashed car had been found near Castaic Lake.
The car had been discovered lying on its side with its back windshield cracked open. There was no sign of Bryce, although his wallet, phone, and laptop had been left behind. While he might have been able to get out of his car, authorities speculated that he could have suffered a head injury in the crash. Despite numerous searches of the area, both by air and foot, Bryce Laspisa has never been found.
Rather than being the unfortunate victim of foul play, Bryce’s parents believe that their son is still alive. A few days before his disappearance, Bryce hadn’t been acting like himself. He had broken up with his girlfriend on August 28, and his parents reported him missing the next day after he failed to give them a promised phone call. After police found Bryce unharmed at a rest stop, he called his family and said that he was fine.
As for the crash near Castaic Lake, some people have theorized that Bryce ran away from home. Several unconfirmed sightings have placed him in Washington, Nevada, and Oregon.

Shortly before noon on October 12, 1944, 20-year-old Georgette Bauerdorf was found dead in her apartment in West Hollywood. Bauerdorf, an aspiring actress and the daughter of a wealthy oil tycoon, was discovered facedown in the bathtub with a washcloth stuffed into her mouth. At first, police thought that Bauerdorf might have drowned after slipping and becoming unconscious, but the autopsy concluded that she had been beaten, raped, and suffocated.
Although all of her valuable jewelry had been left untouched, the killer did steal $100 and a car from Bauerdorf. The car was found 20 kilometers (12 mi) away from her apartment the next day. Police also discovered that a light outside her apartment had been unscrewed and turned off. Her front door was unlocked, which suggested that the killer either had a key or forced his way in after luring Bauerdorf to open the door.
Bauerdorf was a hostess at a Hollywood club that entertained servicemen, so police speculated that the killer might have been somebody she knew there. A coworker told them that Bauerdorf had a strange ex-boyfriend whom she had gone out with the previous month. The man was a serviceman who dearly loved Bauerdorf, but she didn’t have the same feelings and broke up with him. The authorities tried in vain to find the man, but he was never located.
A year after Bauerdorf’s death, the Los Angeles police received a bizarre note claiming that her killer was a soldier who served in Okinawa. “The murderxx (sic) of Georgette Bauerdorf was Divine Retribution,” it said. “Let the Los Angeles police arrest the murderer if they can.”

On January 16, 1973, Michaele Benedict was chatting inside with some friends while her four-year-old daughter, Anna Waters, was playing in the backyard of their home in San Mateo County. At about 2:20 PM, after not hearing Anna for quite some time, Michaele realized that her little girl wasn’t in the backyard anymore. After searching her property for about 30 minutes, Michaele called the police. Initially, investigators feared that Anna had fallen into a nearby creek and drowned, but no trace of her was found in or near the water.
Although the accusation has never been proven, some investigators and family members believe that Anna’s biological father, George Henry Waters, may have abducted her. Waters was a prestigious doctor who suffered from paranoid schizophrenia. His friendship with a shady psychic named George Brody destroyed his marriage with Anna’s mother. He went off to live with Brody in San Francisco after their divorce.
Brody, a mysterious and manipulative con man, insisted that Anna was the reincarnation of a woman he had once known. Strangely, Waters never showed any concern over Brody’s obsession with his daughter. When Brody died in 1981, Waters committed suicide two weeks later.
Years after Anna went missing, her half brother, Nonda, remembered an incident that he and Anna had never told their parents about. A month before her disappearance, Anna and Nonda had been playing in front of their home when an unfamiliar man and woman pulled up to them in a Chevrolet Impala. The couple tried persuading Anna to get into their car but left after she refused. Whether this couple had anything to do with Anna’s later disappearance was never established.

On April 15, 1994, the lifeless body of a nude woman was found floating in the water off a beach at San Diego’s Point Loma community. The woman was horrifically mutilated. Her right leg had been torn off, and other pieces of flesh were either missing or covered in bite marks and bruises. Although nobody could locate her clothes or ID, a butterfly tattoo on her shoulder eventually led authorities to identify the Jane Doe as Michelle Von Emster, a 25-year-old drifter who lived in the area.
According to Brian Blackbourne, the San Diego medical examiner who conducted the autopsy, Emster was alive when she was savagely attacked. Her neck had been broken, and some of her ribs were cracked, too.
Given the severity of her injuries, Blackbourne concluded that Emster was attacked by a great white shark and then died from massive blood loss and drowning. The bite marks on her body, which were too small to have been caused by a great white, probably came from blue sharks after she died. Blackbourne ruled that Emster’s death was nothing more than a tragic accident.
Many shark experts, however, dismissed Blackbourne’s conclusion. Contrary to what we see in Jaws, shark attacks are rare, especially in the waters where Emster’s body was found. Blackbourne confessed that he knew nothing about sharks. He consulted a marine biologist, who later acknowledged that there was no direct evidence of a great white being involved.
Even if Emster had been attacked by a great white, skeptics point out that it could have occurred after her death. After all, a number of strange details about the case are still unanswered. Why, for example, have her clothes never been found? Her roommate, who had dropped her off at the beach the night before her body was discovered, said that Emster was wearing a green trench coat.
The temperature that night was only 15 degrees Celsius (60 °F), so why would she have been swimming naked anyway? And how did she get sand in her lungs? Over the years, a number of theories have been advanced—from suicide to murder—yet Emster’s death still remains a hotly debated mystery.
