I could be wrong, but i thought he said that he tried to contact her a couple times after Daniel died. I'm not sure if he said he tried to call by phone and couldn't get thru or not. But he did say that he left messages "call your dad" on her website and go no reply.
You are correct, I heard him say the same thing. I remember thinking that it was pretty compelling evidence that HKS wasn't letting any of her family call her. It's not just Virgie saying it. It's Daniel (through the PI) and now ANS's father.
I did hear him say that, and also Howard said they'd tried, as well. The whole family situation is just sad. No one was close, for whatever reasons.
