how about this guy Rodney Longman?
https://www.findthemissing.org/cases/4674/0/
the height, weight and eye color (gray) are all about right. hair color is listed as brown but in his picture it is a bit lighter. his face looks a little thinner than the composite sketch but who's to say?
originally missing from Nebraska but according to his info, he was last seen in Miami (no particular date) with another man and a pregnant woman. not clear if the last date known alive was Nebraska or Miami.
as for the intitals on the billfold, it could have been stolen.
I don't know how to do the side by side pics so I can only attach links.
