Nobody knows why Alexander Cahoy died suddenly while hiking the Continental Divide Trail. He was 32, fit and seemingly healthy, an experienced hiker.
"I have to come to terms with the fact that I may never know," said his father, Tom Cahoy of Minneapolis.
The hiker from Minneapolis had been out of contact for a few days when a search team found him June 9 at his campsite in the Colorado mountains. He was in his sleeping bag, his possessions arranged neatly around him. An autopsy produced no answers.
"Everybody says there was no trauma, no distress," Tom said. "He apparently died peacefully in his sleep on top of a mountain at over 12,000 feet."
When fellow hiker Tim Brugman last saw Alex, a couple of days before he died, he was on "a really sketchy section" of snowy trail called Knife Edge, "walking along with ease."
Alex's mother, Julie Cahoy, talked to him on June 4. He'd lost his glasses, so she mailed a spare pair and some cookies to Silverton, Colo. He called to say he'd received them.
When Julie didn't hear from her son for a few days, she called the local sheriff's office, which sent out a search and rescue team. Later that night, she got a call from the coroner.
Alex always loved being outdoors, his parents said. He cross-country skied as a small child, joining the Minnesota Youth Ski League when he was 6 or 7.
