I still believe Lee Peterson helped his son get rid of Laci's body. I have no evidence - just a gut feeling.
I could not understand why a family would help their son to possibly leave the country - unless they knew he was guilty. When Scott showed up in San Diego with a new hair color, a beard and mustache, his brother's driver's license and $10,000 in cash .. it made me a little suspicious that the family knew more than they were telling.
And .. the father will not look directly at people - even during interviews. He looks up or down or sideways - but never eye-to-eye. It's a very telling sign the father has something to hide.
If you're right, I hope the police are slowly, quietly building the case.
