Some reactive Satanists are teenagers or mentally disturbed individuals who have engaged in criminal activities. During the 1980s and 1990s, several groups of teenagers were apprehended after sacrificing animals and vandalizing both churches and graveyards with Satanic imagery. Introvigne stated that these incidents were "more a product of juvenile deviance and marginalization than Satanism". In a few cases the crimes of these reactive Satanists have included murder. In 1970, two separate groups of teenagers—one led by Stanley Baker in Big Sur and the other by Steven Hurd in Los Angeles—killed a total of three people and consumed parts of their corpses in what they later claimed were sacrifices devoted to Satan. The American serial killer Richard Ramirez for instance claimed that he was a Satanist; during his 1980s killing spree he left an inverted pentagram at the scene of each murder and at his trial called out "Hail Satan!" In 1984 on Long Island, a group  called the Knights of the Black Circle killed one of its own members, Gary Lauwers, over a disagreement regarding the group's illegal drug dealing; group members later related that Lauwers' death was a sacrifice to Satan. In particular, self-declared Satanist and alleged member of the Knights of the Black Circle, Ricky "the Acid King" Kasso, became notorious for torturing and murdering Lauwers while allegedly attempting to force Lauwers to declare "I love Satan" during the murder. On November 21, 1998, Jarno Elg, a Finnish Satanist, was sentenced to life in prison for murdering a 23-year-old man in Hyvinkää, Finland, eating some of the body parts and instigating others to participate in a ritual that included torturing the victim.
