There are a lot of things that are just about unthinkable in this one...a little boy being directed to have sex with his mother on his 8th birthday...the first of many such meetings.The boy was introduced by his father to porn when he was seven. There was life in filthy surroundings with hygiene practically unheard of. But they were part of the scene that led to sentencing in luzerne county court of 45 year old Carol Hann for crimes that included child rape and incest. The boy's father, Robert Caravella, awaits sentencing. the report says the incidents happened in homes on North Chestnut Street in Nanticoke and Gould street in Plymouth.
