The rankings are based on the number of victims in a given state by a single killer. Washington State, for example, was the killing ground for perhaps the country’s most prolific serial killer: Gary Leon Ridgway, aka “The Green River Killer.” With 49 confirmed victims (and possibly more) in WA, The Green River Killer terrified Washington residents from 1982 – 1998 before being caught. He is currently serving life in prison.
In addition, this graphic from SecurityBaron.com displays data about each killer, including: their Modus Operandi, method of killing, whether they were caught or convicted, and whether they were executed, are on death row, died in prison, or are serving life in prison.
