I'm not done with thinking WG is involved. Call me crazy, but I saw some signaling going on in the mall video. I still think it is possible that a hand off was going on. JM might not have disappeared her, but he knows who he handed her off to. I have no idea what Hannah was up to that night, but I see someone a bit confused. She had walked off that buzz by the time she met JM. Been there done that. So what happened next?
I agree about WG. I'm not convinced at all that his actions were those of a good samaritan. I'd be really surprised if he was able to entirely sell that one to LE either. I know they say he's in the clear but is he really. Blind Freddy can see from the video surveillance that he was onto HG and not in a concerned way. I do think, though, that JM is involved in her disappearance. Whether he was acting alone or with others time will tell. Hopefully time will reveal all.
