I am a local, having lived in this valley for several years. I did not know Morgan but know many people who knew her. Until fairly recently I was even more local and that's probably why I am so interested in the blog and the situation as a whole. Having read through these threads, I have information on two questions that have come up.
One is about the horse facility behind the house. I haven't been on the premises recently enough to tell you whether or not any specific medications are there. But I can say that meds for horses are kept in two main places (feed room and office refrigerator) and are not locked up or monitored in any consistent way. Lots of people are in and out of these two places and it would not have seemed strange for any person who had a horse or rode there to be close to meds.
The second issue is about snow. I clearly remember reading about M's death in the paper, discussing it with people at my house, and realizing certain things. I thought back to the night she died and the next morning (December 2) and remembering what we did that morning -- we went out to play in the first real snow of the year.
Last winter was a very weird snow year in the valley (the ski and tourist industry freaked out completely). We got almost no snow until December 1-2. It is unusual that there would have been no snow at all in Carbondale until then, but that's exactly what happened last year. That said, Carbondale is noticeably warmer than Aspen (being lower in elevation) and snow that sticks in Aspen often melts right off in Carbondale.
