I just read the story in full. The reason I can't find other news of it is that he (Demmick) hasn't been officially charged, just accused by one of his victims.

Impressive that they went to Congress to raise awareness, but not surprising that hardly anyone reported it.

I'll be just fine and dandy
Lord, it's like a hard candy Christmas
I'm barely getting through tomorrow
But I won't let sorrow get me way down.
