As you say, there are no swans in the cesspool, so we'll see.
The newspapers are reporting nothing about what Shasta is telling authorities about her brother's whereabouts. Which may indicate that he's still alive. God willing!
In the horrible Geraldo interview on FOX, the Dad stated that he had never known this guy, before.
I do not think that the Dad ever wanted anyone killed, or hurt, but I think he did want to kidnap his kids. And when you start messing around with the kind of people that do that stuff....well, this is what happens.
