Do you suspect someone you know might be a psychopath? Evidently, you are not alone. According to a new study, Wyoming has the fifth highest percentage of psychopaths in the country.

A student at Southern Methodist University analyzed crime data to determine which states had the most citizens with psychopathic tendencies. The District of Columbia had the most psychopaths, per capita followed by Connecticut, California, New Jersey, New York, and Wyoming.

Research suggested that West Virginia had the lowest percentage of psychopaths. Vermont, Tennesee, North Carolina, and New Mexico rounded out the bottom five.
