I was watching on older 20/20 ep tonight on WE television. They were intervewing her on what happend. She stated that she was awoken by one of her sons touching her saying "mommy, mommy", she sat right up and saw something out of the corner of her eye.. she got up and saw someone running past her island in her kitchen, and then run out towards the garage, where he droped the knife. She then turned around and saw her boys were hurt started screaming, and called 911
Not one time during the interview did she say she fought with him, that they struggled, and she fought for her life, that that she woke up with him laying on her trying to rape her.
She later realized he must have slit her throat
while she was sleeping on the couch 
Cause everyone can sleep through something like that.!!
That 30 min clip put the last nail in the coffin as for as I am concerend. She did it, and she lied about it!!!!
