UPDATE: Park officials have said that Wieferich’s death has been ruled a suicide.
Authorities in Yellowstone National Park are investigating the death of a concessions worker who had been reported missing after failing to show up for work.
A search began on Tuesday for Kassandra “Kassie” Wieferich, who had reportedly missed several shifts at work and failed to meet a family member the previous afternoon as planned.
After a brief search in the Old Faithful Lodge area, the body of the 21-year-old woman from Twin Bridges, Mont., was located not far from the point she was reportedly last seen by a fellow employee.
Park officials said information about Wieferich’s death was not released by the park’s public affairs office until Wednesday to allow for notification of family members.
The incident remains under investigation by National Park Service rangers and special agents. Additional information was not immediately available.
