Israel Keyes (Alaska & Lower 48, 2001–2012)

Though based in Anchorage, Alaska, Israel Keyes traveled extensively throughout the continental United States between 2001 and 2012. Keyes is notorious for having “kill kits” buried in various states, which he would dig up to commit murders, then rebury. He confessed to multiple murders—including the 2012 abduction and killing of 18-year-old Samantha Koenig in Anchorage—before taking his own life in prison.
