Obviously you were flat out WRONG and a court believed it had PLENTY of evidence to convict Peterson. It didn't convict him for being a piece of Shiite but because of the presence of the bodies EXACTLY where he had been, a location where they would have NEVER been without him. That alone was sufficient.
Now you might argue that this was only coincidental. Maybe but it looks like even GOD himself wanted the SoB to fry. Just looking at Jackie Peterson should have been enough to convince one that he was guilty.
