According to Federal Bureau of Investigation (FBI) Samuel Little is America’s most prolific serial killer with about 50 confirmed killings.
Little has confessed to 93 murders, and FBI crime analysts believe all of his confessions are credible. Law enforcement has been able to verify 50 confessions, with many more pending final confirmation.
Little says he strangled his 93 victims between 1970 and 2005. Many of his victims’ deaths, however, were originally ruled overdoses or attributed to accidental or undetermined causes. Some bodies were never found.
