A serial killer has drawn 10 more creepy sketches of his alleged victims in an attempt to help law enforcement track his killing spree. Samuel Little, a former boxer who has confessed to 93 murders over a span of 35 years, has been drawing pictures of his victims since 1996. The FBI previously released 16 of the sketches, and has now released 10 more in a bid to find out who they were. The alleged victims Little has drawn all appear to be young women and are all wearing lipstick. None of his drawings has been matched with any unidentified murder victims so far, so it’s impossible to know whether the confessed killer is accurately recalling intricate details like the jewelry and hairstyles of his victims—or if he just made it up. Most of Little’s known victims were vulnerable women working as prostitutes.
