The Lords of Chaos was a self-styled teen militia formed on April 13, 1996, in Fort Myers, Florida, United States.
It was led by Kevin Donald Foster (born Kevin Donald Bates; June 16, 1977).
The group gained notoriety for a crime spree that ended with the April 30, 1996 murder of one of the boys' teachers, Mark Schwebes, who served as Riverdale High School's band director.
The Lords of Chaos predate the more notorious Columbine High School massacre in Colorado by three years.
The case has been documented, most extensively in Jim Greenhill's true crime book about the case, Someone Has to Die Tonight.
It is also the subject of a Dateline NBC special, When A Killer Calls, as well as being mentioned in Lords of Chaos: The Bloody Rise of the Satanic Metal Underground by Michael Moynihan & Didrik Søderlind, the book even borrowing the group's name.
