All they need do, is give these boys a polygraph. That's all. And IF Paulus knows his son is soooo innocent, why would he hesitate? Of course, they might need permission from the Muhderland..LOL.

So what happens if N is found in the sea, what's left of her, a la Laci Peterson? If J and the three still won't crack, they'll just say she went swimming and, being drunk, drowned. Right from the getgo they've taken great pains to blame the victim and smear her name. To hear J talk, he did N one favor after another that night, and then, after acting like a total gentleman for hours, suddenly leaves a defenseless girl, if drunk...according to him...to sleep on the beach. Doesn't pass the smell test.
