Anyone have any clue who this could be?

For basically an entire decade or even a little longer, this man was considered the go to expert for all things child abuse. The thing is though, he often was the one doing the abusing. Hundreds and hundreds of children across the country that he would meet with to identify if they had been sexually abused, he would then abuse. He would then say the child had been abused and day care workers or parents would be arrested. Our "expert" would then have several followup sessions with the victims where he would abuse them again before moving on to the next town. Even more crazy is that he was usually paid for these interviews where he was abusing children.
