Aloys Krost, a 62-year-old physics professor from Germany, went missing on October 1, 2013, while hiking the Pinnacle Trail in Lake Arrowhead, California. Krost was visiting the U.S. for a conference when he joined a group hike in the San Bernardino Mountains. At around 5:45 p.m., he became separated from his hiking companions and was never seen again. Despite being an experienced hiker and hunter, Krost had no hiking equipment with him when he vanished.
Extensive search efforts, including rescue teams and search dogs, were launched to find him, but no trace of Krost has been discovered. The search area, known for its rugged terrain, presented significant challenges. Investigators believe he likely became lost in the wilderness, but the lack of any physical evidence has left the case unsolved. Krost's disappearance remains a mystery, and authorities continue to seek information that could provide answers.Last Seen: Oct 1, 2013
