Joe Fanciulli, a retired police homicide detective with more than five decades’ experience, is conducting an independent investigation into the disappearance of Andrea Knabel. The single mother of two and member of “Missing In America” which specializes in finding missing persons vanished in Louisville, KY, on August 13, 2019. She was living with close family members, including her mother, at the time of her disappearance.

According to claims made by people he interviewed, Fanciulli says, “There was discord there when Andrea was staying there.” He also claims that Andrea was locked out of her mother’s home on the night she disappeared.

“My fear is that she reached out to the wrong person – somebody she could not even have realized she was potentially at risk with,” says the retired detective.
