Police have confirmed more than 36 cases so far, a tally that puts Little among the deadliest serial killers, according to the FBI.
He strangled all his victims and dumped their bodies, often in wooded areas. Without a gunshot or knife wound, many of the deaths were blamed on overdoses or accidents and murder investigations were never opened. The victims were often involved in prostitution or addicted to drugs. Their bodies sometimes went unidentified.
According to the FBI, Little remembers his victims and the killings in great detail. He remembers where he was, and what car he was driving. Through the portraits you can see he remembers his victims vividly. He is less reliable, however, when it comes to remembering dates.
