Samuel Little, 78, may certainly be among the "most prolific serial killers in U.S. history" according to an FBI report released this week.
Little has told investigators about 90 murders he may have committed as authorities have evidence of his ties to 34 of them. He began speaking in exchange of a prison transfer.
Investigators are racing to identify as many of his victims as possible because Little is in poor health and will likely die in prison while he serves multiple life sentences.
His history of crimes started in 1956 when he was first arrested for charges like shoplifting, drug charges...His victims span more than a dozen states from coast to coast, while he can't remember the date, he remembers the victims and details about the killings.
