The "plastic" for the bed, suggests premeditation. Which was it...drunk impulse or premeditation? DW would have NEVER slept with a plastic mattress cover. He was to hot-blooded and perspired easily..(JMO).. Ever try to sleep on one of those? Talk about "sweating"...geeze.
I think DW was only trying to protect his son from the publicity concerning the kids porno exploration, because he never, ever dreamed it would go this far when he said it was HIS porno.
DW was acting like a father, sheltering his own son, but didn't know it was going to be the entire MOTIVE in a case against him.

If Danielle was a sleepwalker, was there a gate at the top of the stairs so she won't fall down them at night? If not, maybe she wasn't a sleepwalker. Also, wasn't it the masterbedroom where Damon shampooed the carpet because of the dog. Maybe it wasn't the dog that peed there, maybe it was Danielle when she died???
