Samuel Little: Inmate is most prolific serial killer in US history, FBI says

The inmate who claims to have killed more than 90 women across the country is now considered to be the deadliest serial killer in U.S. history, the Federal Bureau of Investigation said. Samuel Little, who has been behind bars since 2012, told investigators last year that he was responsible for about 90 killings nationwide between 1970 and 2005. In a news release on Sunday, the FBI announced that federal crime analysts believe all of his confessions are credible, and officials have been able to verify 50 confessions so far.
