I assume law enforcement is not telling us everything they know about the recent bank robbery, allegedly by a woman, but it’s fun for we armchair detectives to play with this. It seems likely that an adolescent might be involved. This boy or girl meets the bank robber behind some obstruction, and very quickly receives identifying clothing, or perhaps a disguise (it could be a man), plus the loot, stuffs it in a bag which is put in the bike basket, and rides off, visible and yet invisible to everyone. The robber than walks away in plain daylight, but relatively quickly getting out of sight, and maybe out of town.
I think it would be fun for other people in town to suggest their own ideas about the case, and share them in letters to the editor. Who knows, maybe someone will come up with something useful.
