Another thought on the recently-released image:
Consensus on here seems to be that Vicky, at least, has been careful to avoid places where security cameras might catch a view of her. If it IS Casey in the image, he doesn't seem too worried about being caught on cam...not even bothering to wear a mask which might partially hide some details. If Vicky is still alive and is the one pulling the strings, wouldn't she be wary of local businesses which might contain security cameras?
Just thinking here.
