FBI Confirms This is The Most Prolific Serial Killer In American History; And No Death Penalty

The 79-year-old inmate was already serving three consecutive life sentences in California when he confessed to another 90 killings last year. On Monday, the FBI confirmed that its investigators verified 50 of those deaths and are seeking help to confirm the rest of the unmatched confessions.

The FBI’s Violent Criminal Apprehension Program, also known as ViCAP, began connecting Little to unsolved murders after a Texas Ranger tied the inmate to a 1994 cold case in the city of Odessa.

Not long after, Little confessed to strangling 93 women across the country between 1970 and 2005.

Gary Ridgway, dubbed the Green River Killer, was convicted of 49 murders and confessed to about 20 more. Ted Bundy and John Wayne Gacy each murdered upwards of 30 people, but Bundy was suspected of more.
