There is a possibility that Mayfield simply touched the same bag at a store.

Yeah, maybe. But there was enough of the print there and in good condition to lift it, study it and match it. I reckon if it just was a casual touch they wouldn't have enough to analyze.

Had Mayfield visited the area?

BTW, that's pretty good for the Alphabet Soup crowd to have spotted this fellow's fingerprint in the wreckage, whether or not there ultimately is a link. FBI and CIA getting their acts together.
