Chris's Myspace page
After the OJ maneuver, his guilt is getting more and more self-substantiated.
Lot's of people consoling Chris (recently) on his Myspace page. If I were the KBI, I'd be lloking at his private messages to them to see what they were consoling him about. The timeline looks suspicious/coincidental. I would be looking to see if he was telling them that his girlfriend was stepping out on him. Might establish motive.
...but then again, I'm not a cop...so what do I know?
