His posts to CDC's FB were all over the place, but came in clusters, and at all different times of the day.
I wonder if he thought he was being crafty. A group of posts all coming from one location in the morning, a group in the evening from another, etc., with none of the locations tracing to him.
Just a thought.
Another thought I have had since the beginning is that his extremely risky behavior regarding the FB posts is an indicator of wanting to be caught, and stopped. If that is the case, he may very well have been posting from the comfort of his own living room, just waiting for LE to come get him.
He seems relatively self aware, he knows what he is, and I don't think he likes it. This may sound out there, given who we are talking about, but I really don't think he wanted to kill KB, but knew that sooner or later he would 'have to' unless he was caught.
