Thanks for the ping, Ho...n
I'm certainly hoping there is a deep investigation of this whole Berg death. No matter what is discovered in the end, there are easily enough anamolies in this man's life to suspect linkages that have not yet been public. He may not have been anything but an innocent bystander, but somehow he may be a nexus around which an investigation might really turn up some interesting and useful new information.

I believe that more than Nick himself, those around him merit deep investigation. His father, his sister Sara, and Dylan Wrynn, who, while not assured to be in his circle, would likely have known him as well.
