Jan...it probably wasn't him, but my relatives told me that he had approached them panhandling down on Quarrier St. and they recognized him.
I guess, on the West Side, there are all sorts of characters who approach people, unfortunately. I've been to the Dollar Store there right on Wash. St., if that is the one you are referring to, and always felt a bit uncomfortable because of the proximity of the many bars, knowing the way desolute characters frequent the area.
In PM, I can tell you a description of my stalker
