It was Hass who lead his partner Derek to his death. Here he is:

I've skied with him (I did not realize who he was until later) and he's a pleasant enough fellow to be around. He very well may have changed as a friend of his claims. On the other hand, I know that a two or three years ago he drove recklessly in a snowstorm despite being asked to take it easy by the afore mentioned friend. He ended up losing control and totaling someone's vehicle, so maybe he hasn't changed that much. It would, however, be extremely inappropriate for someone on this list to contact any of his employers to badmouth him.
I also happen to know the AMC hutperson who had to leave MacDonald Barr to die. It made the read all the more powerful. Not something I would ever want to experience.
