Crimes involving Satanism or the occult

Roderrick Justin "Rod" Ferrell (born March 28, 1980) is an American murderer and cult leader. He was a member of a loose-knit gang of teenagers from Murray, Kentucky, known as the "Vampire Clan". Ferrell claimed to be a 500-year-old vampire named Vesago, a character he created for himself after becoming obsessed with the role playing game Vampire: The Masquerade. It was his mother, Sondra Gibson, who first introduced this game to Rod. In 1998, Ferrell pleaded guilty to the double slaying of a couple from Eustis, Florida, becoming the youngest person in Florida on Death Row at that time. Originally sentenced to death, Ferrell's penalty has since been reduced to life imprisonment.

Scott Edgar Dyleski (born October 30, 1988) is an American murderer, convicted of murdering his neighbor, Pamela Vitale, the wife of prominent attorney Daniel Horowitz. He received the maximum penalty allowed by the law, life in prison without parole. As a juvenile at the time of the murder, he did not qualify for the death penalty. The murder was committed on October 15, 2005, when Dyleski was 16 years old. He is currently serving his sentence in California State Prison, Corcoran. In 2018, Dyleski's sentence was reduced to 25 years to life in prison, after the state of California passed Senate Bill 394, which gives juveniles tried as adults and sentenced to life without parole a chance for eventual freedom. He will be eligible for parole in 2030.

Sara María Aldrete Villareal (born September 6, 1964) is a Mexican serial killer who was convicted of murder while heading a drug-smuggling and human sacrifice cult with Adolfo Constanzo. The members of the cult, dubbed by the media as The Narcosatanists (Spanish: "Los Narcosatánicos"), called her The Godmother ("La Madrina"), with Constanzo as "The Godfather" ("El Padrino"). The cult was involved in multiple ritualistic killings in Matamoros, Tamaulipas, including the murder of Mark Kilroy, an American student killed in Matamoros in 1989. She received a sentence of 62 years.

Sean Richard Sellers (May 18, 1969 – February 4, 1999) was an American triple murderer, one of 22 persons in the United States since the reinstatement of the death penalty in 1976 to be executed for a crime committed while under the age of 18, and the only one to have been executed for a crime committed under the age of 17. His case drew worldwide attention due to his age as well as his jailhouse conversion to Christianity and his claim that demonic possession made him innocent of his crimes.
