which serial killer killed the most people

The most prolific serial killer in recent history is generally considered to be Samuel Little, who confessed to murdering 93 women between 1970 and 2005. The FBI's analysis supported the credibility of his confessions, making him widely described as the most prolific in U.S. history. He died in December 2020 while serving a life sentence. Please note that counts for historical cases can vary depending on sources and how victims are documented, but Little’s attribution is the most extensively cited figure in contemporary reporting.
