I haven't had the heart to keep up on the threads but have kept up in prayer.
I read somewhere that she has been in this state about 13 years and that her problems may have started as a result of domestic violence (it was implied that he choked her and she suffered her stroke or heart attack as a result of that, that she showed signs of damage from a choking incident but that they didn't look for it until a year after the event.) Since then I've felt very strongly that the husband is simply trying to kill his wife so that his crime will be covered up. He fears her recovery more than her death.
Does that sound like a pretty accurate reading? It doesn't seem like a 'right to die' case as much as it seems like a premeditated long term murder attempt.
