It's possible she got hypothermia quite early in her trek, given her gear selection for the conditions. Hypothermia would drive her off the trails and into a drainage possibly, making any contact with other hikers a moot point. If that is the case, she might never be found. It's amazing the conspiracy theory's floating around on FB, I sincerely hope her mother does not look at the many threads. To me, this is a scenario that has played out many times over the years and I see nothing suspicious or strange about any of it. The mountains this time of year, lull the inexperienced in and they pay a heavy price. The most frustrating part of it to me, is no matter how many times it happens, somebody else falls into the same trap in due time.
