According to CBS affiliate WJAX in Jacksonville, new court documents show Kessler admitted to investigators that she, had been running from the FBI for 25 years and was wanted in several states.

They also reported a man questioned by the FBI said investigators told him they were looking into Kessler possibly being a serial killer.

Kessler disappeared from Butler County back in 2004.

However, police say she was living under an assumed name and using a fake Social Security Number in Florida.
