A fresh wave of forensic evidence and canine alerts has reignited the chilling possibility that Charles Manson and his murderous family left behind a far larger trail of bodies than the world ever knew. New searches at two abandoned California ranches, once the cult’s strongholds, have uncovered chemical signatures consistent with human decomposition, prompting law enforcement to reconsider decades-old claims that Manson himself boasted of killing as many as 35 people.

The investigation, led by veteran police sergeant Paul Dosty and his cadaver dog Buster, has focused on the Spawn Ranch in the hills above Los Angeles and the remote Barker Ranch near Death Valley. Both sites were central to Manson’s “family” during the late 1960s. Dosty’s work, supported by forensic scientists from Oak Ridge National Laboratory, has detected volatile organic compounds that match those of decomposing human remains.
“We have multiple dog alerts, and the chemistry is strong,” Dosty said. “We believe we are very close to finding human remains.”
Manson was convicted of nine murders, including the infamous 1969 Tate-LaBianca killings that shocked the nation. But for decades, whispers from former followers and even Manson himself have hinted at a much higher body count. In a 1993 parole hearing, Manson said, “Maybe I should have killed 4,500 people.
Then I would have felt better.” Former family member Susan Atkins told a cellmate that there were “three people done in out in the desert.” Sandra Good, another prominent Manson follower, put the number at 35 to 40.
The new search has focused on a gully at the Spawn Ranch, where Dosty’s dog Buster alerted repeatedly, and a second cadaver dog, Kazam, confirmed the scent. Soil samples taken from that site, 18 inches below the surface, revealed chemicals that Dr. Mark Wise of Oak Ridge said “could be consistent with the presence of buried remains.”
Ground-penetrating radar also detected an anomaly in the same area, uphill from where the dogs alerted. “It’s a very discernible circle of rocks,” Dosty noted. “That’s a good area for us to pinpoint.”
But the dig at Spawn Ranch was cut short after crews encountered layers of asphalt and concrete debris dumped years after the Manson family left. The property owner asked the team to stop. Despite the setback, Dosty remains convinced.
“The dog continues to alert. The chemistry is still good. It would take an extraordinary effort to dig them up using mechanical means,” he said.
At the Barker Ranch, a similar story unfolded. In 2008, Dosty and a team of scientists conducted a two-day dig but were limited to shallow pits no deeper than three and a half feet. The local sheriff’s office declared the results conclusive, saying no human remains were found.
But Dosty and Dr. Arpad Vass, a world-renowned forensics expert, disagree. “The holes were too small, too shallow,” Dosty said.
“We should have dug 10 feet deep, 12 by 12 feet.” Vass’s instruments continued to detect chemicals associated with human decomposition at the site.
The Barker Ranch was where Manson and his followers hid after the Tate-LaBianca murders. It was a place of paranoia and violence. Former family member Linda Kasabian recalled that Manson once beat her and that “the atmosphere was very heavy.
Everyone was paranoid.” Another former follower, Dianne Lake, said that “anyone who crossed their paths was definitely in danger of being killed.”
Among the potential victims are a girl who “was not fitting in,” a backpacker who vanished, and three bikers who Susan Atkins brought to the ranch. Atkins said she never saw them again. There is also Ronald Hughes, the attorney for Manson follower Leslie Van Houten, who disappeared during a break in the trial after arguing with Manson.
His body was never found. James Willard, a family associate, was found shot and decapitated; his wife Lauren was buried in a basement. John Philip Haught, known as “Zero,” died in a suspected Russian roulette incident with a fully loaded gun.
Filippo Tenerelli, a biker with family ties, was found shotgunned to death near Death Valley, his vehicle found covered in blood on the way to Barker Ranch.
The Manson family’s killing spree extended beyond the two famous nights in August 1969. They murdered musician Gary Hinman after a 𝒹𝓇𝓊𝑔 deal gone wrong, and ranch hand Shorty Shea, whose body was finally found in 1977 after a confession. Yet even with these nine known victims, the list of missing persons connected to the family remains long.
The mystery of the missing victims has haunted investigators for decades. “The Manson family was a cult of cold-blooded killers,” said Ed Sanders, author of “The Family.” “They murdered without hesitation or remorse.
They enjoyed killing. And they wanted to 𝓀𝒾𝓁𝓁 as many people as possible.” The lack of a national missing persons database in 1969, and the primitive state of forensic science, left many cases unsolved.
Now, with advances in canine cadaver detection and soil chemistry, the search is resuming. Dosty and his team plan to seek permission for a larger, deeper dig at the Spawn Ranch using heavy equipment. “These are brothers and sisters whose sibling or child walked out the door one day and was never heard from again,” he said.
“I’m positive that an animal like Buster can be used to help identify a lot of the mysteries of history.”
The Manson case, four decades after the murders, continues to grip the American psyche. Every time one chapter closes, another opens. The hunt for Manson’s missing victims may finally be nearing its end.
But as the soil at Spawn Ranch and Barker Ranch continues to hold its secrets, one question remains: How many more bodies are buried in the silent, rugged hills where Manson’s family once roamed?
