Just a little bit about hiking the PCT - my son-in-law had a chance to hike the first part of the trail last year as part of a veterans group. He is 28, a big strong guy, used to the outdoors, and he served two tours in Iraq when he was younger so he was trained for the desert and mountains. In the first week, they saw rattlesnakes and scorpions every day, which was kind of freaky, and he had no wifi until he was near a town. So he usually couldn't call the family until nightfall if he was lucky. The rocky trail is not easy on the feet, and he kept sliding and spraining his ankle until it started swelling and he had to give up the hike. As others have mentioned, parts of the trail were closed in the past year due to mudslides and avalanches, and the hikers were warned about snow and ice up high (if they could make it that far). Based on all that, I would say something has definitely happened to this young man.
