You're not the first to suggest it.
"Could there be money on the table for a matching organ that's needed now and Terri's a match? Immediate cremation and who's to know."
Now, THAT would definitely add a new, sinister dimension to the story. Let's pray that it is just wild speculation. Given the leading characters though, I think nothing is morally beyond them. It is already known that Felos has a book in the works on Terri's story and is a big pro-death advocate who fancies himself with godlike powers, as per quotes posted from his previous book. Still, it is a bit too morbid to contemplate.....at this point. Besides, if there were toxicity in the organs from the dehydration process, wouldn't that render them useless to a potential recipient?
IMO .. it is wild speculation
