The very fact that it is being alleged that the cause of death cannot be verified, is if you think about it, heavily trending against any form of violent death, even usual stranglings or asphyxia, and leaning toward some sort of drug overdose etc.
I also find it very curious that it is only now, after body found and all, that it ever hits the papers that MR VD was entertaining yet another person, in the home, while Mrs VD was out at the bar.
How many different lies does it take to establish that a person is hiding guilty knowledge?
There is very little to indicate that Westerfield did anything other than freak, when he learned that he had a corpse or other nasty crime evidence riding along with him in his camper-van.
BUMP and Ditto!! FDA
