An imprisoned murderer is being investigated after confessing to 90 killings across four decades in the US. “Over the course of that interview in May,” said Palazzolo, who was sitting down the hall combing through data with Williamson, “he went through city and state and gave Ranger Holland the number of people he killed in each place. Jackson, Mississippi—one; Cincinnati, Ohio—one; Phoenix, Arizona—three; Las Vegas, Nevada—one.” In total, Little confessed to 90 killings, and Palazzolo and Williamson have been working to match up evidence to as many confessions as they can. Authorities first announced Little’s confessions earlier this month, but the Federal Bureau of Investigation reported Wednesday that its Violent Criminal Apprehension Program (ViCAP) has confirmed 34 murders so far, with many others still pending confirmation.

“Little will be confirmed as one of, if not the most, prolific serial killers in US history,” Bland said in a statement. The FBI said it was working with the Department of Justice, Texas Rangers and dozens of state and local agencies to match Little’s confessions to unsolved murders across the country. The FBI reported Little was actually charged with killing women in Mississippi and Florida in the early 1980s but escaped indictment in the case in Mississippi and conviction in the other.
