(AP Photo/George Frey) (Newser) – Booze and a late-night hike in freezing temps might seem like a combination with the potential to go horribly wrong, but it was the added element of lost car keys that took a turn for the deadly in Utah's Provo Canyon. As Weather Underground reports, 20-year-old Hadley Boberg and a 21-year-old male were returning Wednesday from such a hike when they discovered that they'd lost the keys to her Jeep. They searched in vain for the keys, but as temps slid into the mid-20s overnight, Boberg at some point lost consciousness. Officials responding to her parents' report that she was missing found her body the next day. The male, who has not been named, was found wandering nearby; officials noted that he seemed confused and evasive and initially suspected him in Boberg's death. An autopsy later pinpointed alcohol and exposure as the cause of death.
