They tried to contact her, and Stern prevented it. I don't know how many sources you need. We now have Virgie, the private eye that Daniel spoke to and ANS's father, ALL SAY THE SAME THING.
The only source you would want to hear from is Stern, and he's a proven liar.
Daniel's friends, Ray Martino, maybe the Shelly's/Thompson, etc. could all shed some light. Even Larry might have some helpful info.
Also, didn't Ford Shelly say in court that when his daughter, Reilly (sp), wanted to call him the day of the clown video so she could leave because Anna was acting so strange and she was scared, that Howard told her she couldn 't because the phones were disconnected. Meaning perhaps that Anna also couldn't call out.
Does anyone remember this?
