What I heard was that at least three of her kids had never seen sunlight. I wasn't quite sure about it, but she'd been pregnant six times and three of her kids had been brought up solely in the cellar. But there was also some thing about how him and his wife had a few kids or grandkids of their own, so maybe he pulled the cult-story on three of them? There was a big page about the wife and three kids who grew up with normal lives, not knowing anything about what husband/granddad had done to their granddaughter/mother.
Also, I read the newspaper in town today; First four pages were about this, the next page was about a woman whose house was broken into, she was severaly beaten and her two kids died from their injuries, the next page was something about a little kid finding a buried treasure, then a dog that was attacked by some other dog while trying to defend her 75-year old owner which might die, and finally a two-page article about an Iraqi girl who fell in love with a british soldier and was attacked by her father when he discovered it. Her mother cried for her brothers to try and stop him, and when they found out what she'd "done" they helped the father beat and stab her to death. Happy, happy world.
