Actually, I posted too soon. I just got home, and my wife heard from Brittany. He took a turn for the worse
She said, "today has been hard", and that's probably why she hasn't communicated. I'll post her contact information for those of you who requested it.
Her dad is currently in the hospital in Dubrovnik, Croatia. They are paying a lot of money for an apartment close, so any recommendations are appreciated. I'm not sure if they can move him, but I'm trying to find out.
