Sounds like he isn't rational. As has been said, his fate may already be sealed.

I feel bad for his family and friends.

Hikermor, thanks for your service. I have an M.S. in Animal Ecology but moved over to a more technical field in grad school when many government grants dried up. I always had a secret desire to be a national park ranger - not so much enforcement but more research or service (if there there is such a thing). Too late now as retirement is in sight. Instead I'll just enjoy the outdoors I love so much.
