Samuel Little is a self-confessed serial killer responsible for brutally murdering more than 90 people. The 78-year-old is in jail, and he's been sketching his alleged victims, some of whom haven't even been identified.
The FBI just released 10 of his sketches with the hope they will soon discover the identities of the women Little says he killed. Sixteen other sketches were previously released. Little is the most prolific serial killer in the U.S. He is currently in prison after being convicted of killing three women in California.
