I just spoke to the office of the avian vet who did the necropsy on Neo. He said there were lesions on his liver and kidneys. He believes it was either a toxin or infection. He wants to send samples off for further testing so I won't know for sure until after July 5th. He does think it's possible that it was something he was born with. If anyone here has any insight, even if it is a guess, I would welcome your ideas.
