The girl whom Ranzenberger raped for years, testified at his sentencing calling him a “psychopath, monster.” She said “He’s smooth, charming, and manipulative… He was able to hide the monster he was in every word he spoke. His coworkers and family didn’t know he was a child molester.” The victim described Ranzenberger as “a slug of man” and “a pathological liar.”

They are hiding in plain site. This girl's point that he was charming is important. Duplicitous cons are always charming. They groom the children but also use the same personal skills to con adults to trust them with the kids or to not suspect them.
