No disrespect to your thoughts and point of view but WC’s body language are far from that of a socially awkward individual. Behavioral analysis has been practiced for many years by investigators. If you’re a trained observer you can distinguish between social ineptitude and high anxiety while answering questions. WC may just be a guy, no doubt, but it’s my opinion that his body language contradicts much of what he said. Now, he may not care one bit about a missing girl and may even find it amusing. Feigning concern for the situation could account for some of his tells and erasures.
