Thus it seems that Barbour's ideas about Satanic cults came not from any personal experience in one, but instead from watching false, stereotyped caricatures of them horror movies and sensationalized television shows. For another excellent in-depth look at Satanism in popular culture, see folklorist Bill Ellis's "Raising the Devil: Satanism, New Religions, and the Media" (2000, University Press of Kentucky).
Not only is Barbour not the first person to claim to have killed far more people than she likely did, but she's also not the first to have falsely claimed to have participated in Satanic serial killings.
A woman writing under the name Lauren Stratford authored a best-selling 1991 book titled "Satan's Underground," in which she described, in gory confessional detail, her first-hand experience inside a Satanic cult. Stratford admitted to horrific acts, including torture killings and killing babies in the name of the Devil.
The book was enormously popular and influential, especially in Christian circles, during the "Satanic panic" hysteria that swept across America in the late 1980s and early 1990s. Later investigation revealed that Stratford's confession was completely false; she had never joined any Satanic, serial-killing cult. It was all made up for attention.
