2. Frederick Cecil McLean
Widely believed by cops to have sexually abused several children—one as young as five years old—Frederick Cecil McLean has been in hiding since 2005 when US Marshals issued a warrant for his arrest in California.
With strong ties to the Jehovah’s Witness church, McLean is believed to have used the institution to get close to children so he could abuse them. As the owner of a successful car restoration business, he is believed to have sold all of his assets after being confronted by his family.
