An investigation of the former home of Charles Manson's "family" could turn up evidence of other victims of Manson and his followers. There are reports of hitchhikers who came by the ranch and were never seen again, and one of two women who came to the ranch and fled in the night to go to the police, claiming Manson had threatened them.
It is entirely likely that Charles Manson and the Family had more victims than the Tate-LaBianca murders indicated, but, as a former investigator says, those were the only murders they could solidly link to the Family. A criminal enterprise like the Family would have readily killed outsiders to keep them quiet, or the other victims could have been early casualties of "Helter Skelter."
Serial killers are frequently only charged with a portion of their crimes. Ted Bundy was charged with one murder in Utah, an abduction in Colorado, and five murders in Florida, for which he was executed. But according to other victims discovered and Bundy's own confession, he likely murdered at least 20 women. Gary Ridgeway, the Green River Killer, is believed to have killed 49 prostitutes and runaways, but he said, "I've killed so many women I've lost count." Russia's Andrei Chikatilo has one of the highest confirmed body counts in the history of serial killers, at 53 known victims, but his count could also be higher. As we all know, serial killers are known liars. The reverse of this is also sometimes true. The hundreds of victims Henry Lee Lucas once claimed has since been scaled to a confirmed three; his mother, his girlfriend, and his former landlady. And there's no way to know how many of his patients Dr. Harold Shipman murdered, although some estimates place the number in the hundreds.
Happy belated Saint Patrick's Day. I hope you spent the evening like I did, getting drunk with my significant other while listening to a classic Irish rock band at an American version of an Irish pub. I also hope your hangovers are gone.
