Yes, I'll play devil's advocate too, it would help prove a guy I know isn't involved in all this. Lori's wearing a hooded jacket and boots, black leggings are plenty warm in this weather (not that I know from experience). But, Alex who appears with Lori, in Alex's truck, never wears anything during any of those clips other than the heavy jacket and hood. This guy is wearing a thinner jacket, looks like my friend...walks like my friend...built like my friend. Ugh. I'm getting sick.
ETA: I've watched all these clips again and again. I'm not convinced it is or is not Chad. The Nov 24th could be the same man as the presumed Alex. It could be. Hopefully LE can figure this out with other data.
