There is a frustrating tendency among those who were there to not want to give details about what happened. The information I received was useful to state they did CPR, but the person was very adamant that they would provide no other information, but did say things which might be personal in nature otherwise. I am most interested in the events of the day leading up to the incident, specifically if there were warning signs, and then S/S at the time, and what happened. People don't seem to want to say things like that. It's always the same, "very sad", "I'm devastated", and so forth. I get that, but losing your head and having one's emotions won't bring back the person. If anything, telling the details of what happened might help some body.
Mike was known for certain types of writing and logs as well as over the top hike event posts. Things like his Ortega Double last month. He didn't do it, and if you read his logs, he talked frequently about his energy being off. Mike wrote about being diabetic in a log a year or so ago. https://hikearizona.com/x.php?x=136414
I lost a hiking partner in Tucson right after I moved to Phoenix in 2015. I suspect an MI. His wife responded to an email of mine informing me of my friends death, but basically just said, "stop emailing me and take his address out of your rolodex". Clearly, information would not be forth coming.
I do look for the details of this event as I think things like this are better shared, because as anyone who has knowledge of heart attacks knows, warning signs are usually present for days before, sometimes much longer than that.
May have had a low grade fever? Was sweating even hiking down the hill.
From his November 26th A Trail log. If he was doing that, he may very likely have been ignoring warning signs for quite a while.
