Stacy was last seen while visiting Yosemite National Park with her father and six others on July 27, 1981. The group reached a cluster of cabins designed for overnight stay at Sunrise High Sierra Camp, tied up their horses and went indoors to freshen up. Stacy changed clothes and left the cabin, carrying her camera, so she could photograph the lake. Stacy invited her father to join her, but he declined and an elderly man from their group went with her instead. They went downhill towards the lake and the rest of the group watched them from above. They saw Stacy's companion sit down. Stacy walked further on towards the lake, went behind some trees and disappeared from sight. After a few minutes, when she didn't return, the other members of the group went to look for her. An extensive search of the park, involving helicopters, dogs and dozens of volunteers, turned up no indication of Stacy's whereabouts. The only trace ever found of her was the lens from her camera, around the treeline area where she was last seen. She lived in Saratoga, California in 1981.
