Hi Rich,
The only one of those photos with any hope of revealing anything is the center photo in that is shows the back side of some of the drywall.
One piece toward the left against the wall has two lines of what looks like writing, unfortunately though, even zoomed to 400% I cannot make the writing out.
To the right are two pieces with the backside showing, and have end tapes on them, but again, I cannot make anything out on them.
What part of South Florida are you in: Miami-Dade, Broward, Palm Beach or Southwest Florida over by Naples and Ft. Meyers? What city?
Do you have any other photos which may show the back side of the drywall with writing on it?

Typically, all of the drywall is purchased from one distributor at the same time, and typically the drywall would all be the same brand. The different color may be from exposure to sunlight, or it may be from different brands (different brands are not all the same color) from having to run out and buy a few more pieces, unintentionally mixing brands.
there appears to be no markings to indicate this is Chinese drywall.
And no markings to indicate it is not Chinese drywall. At this point I would not want to presume either, so do not take my statement as meaning it may be Chinese drywall, only as meaning that you do not know either way.
I am a construction consultant (

- First go into the garage attic and look at the top side of the drywall, if there is no second floor over the garage the backside of the drywall should be visible as the garage ceiling is usually not insulated. Always start with the easy stuff first.
- Second would be to go into the attic over the living spaces and move some insulation around, seeing if you can find anything there, but moving insulation around is not a real fun thing to do.
Also my copper looks OK and I have no sulphur smell.
