There are tons of videos, not just this picture. In one video a lady is heard saying to him, “Hi, Steve.”

1) another Freeper pulled up a Steven Paddock who was a former employee at NASA...
2) he had a pilots license which is very NASA like
3) its being rpoerted by AP and others he lived in Melbourne Florida which is 30/40 mins from NASA, Cape Canaveral...
the pink shirt the guy is wearing says NASA on it
That “Steve” part sounds dubbed in to my bad ears. Not saying it isn’t him though. Sure looks like him, NASA T-shirt fits, girlfriend looks like it could be Dunlay, etc.
