The FBI has confirmed an imprisoned murderer who confessed to 93 murders over four decades is the most prolific serial killer in US history. Police have matched Samuel Little, 79, to 50 cases from 1970 to 2005 thus far. He has been serving life in prison since 2012 for the murders of three women. Little targeted vulnerable individuals, mostly black women, many of whom were sex workers or drug users, officials say.
The FBI has released sketches made by a serial killer of his alleged victims, in the hope that they may help solve dozens of unsolved homicides. Samuel Little, who is serving a life term without the possibility of parole after being found guilty in 2014 of three murders in California, last year confessed to killing 90 women over nearly four decades, which, if confirmed, could make him one of the deadliest serial killers in American history.
