You can speculate that it could be many things but the issue with most of these locations is they have illegal building code and health violations, they usually get shut down when the town decides to run inspections across all of the businesses in that area. You have to be careful if the owners avoid inspections, thats when usually the police step in and raid the place.
I'm not an expert, but don't town inspectors drive official Edgewater labelled cars? I see them being driven around many other towns.
And someone mentioned "unmasking" the johns. Very hard to do without AI/face recognition unless you know them or ask for ID. 20-30 random guys walking into a building and it'd be difficult to guess where they are from, unless she's photographing license plates and doing searches.
My guess is since Edgewater is a really rich people town, she's probably a PI hired by a wife suspecting her husband of cheating.
Or it's Mary Murphy doing a story on massage places/sex trafficking after she did one on Flushing a couple of months ago?
