I grew up in Calaveras County California and went to school with a person I know to be a solid citizen. She later moved to Oregon and lived near and went to church with Robbie Parker when both lived in Oregon. Parker and his wife moved to Connecticut after that. From her I got a different account of things. Parker is an ordinary human thrown into a media circus and extraordinary events. He and his wife were both freaked out and horrified at events, as any rational person would be . I will go into more detail later but I can explain why the nervous smile on his face and why I find it plausible. Bottom line - he is a real guy with a real daughter that really [bleep] died that day.
I said this before and I will say it again. I find it totally plausible. I understand why some might find it odd. But I would caution and ask how you would feel if your daughter died that day, and because of strange circumstances everyone went around calling you an actor.
