Samuel Little

If what he says is true, Samuel Little would be one of the worst serial killers in U-S history.

The 78-year-old claims that between 1970 and 2005, he murdered 90 people, mostly women, around the country. That includes some in Tampa, Plant City, and elsewhere around Florida.

Now investigators, including University of South Florida forensic anthropologist Erin Kimmerle, are trying to determine the validity of Little’s claims, as well as the identities of some of his victims.
