Case closed: Skeletal remains are thought to be hiker missing in Rockies since 1983

Rocky Mountain National Park, Colorado — Skeletal remains found in Colorado's Rocky Mountain National Park are believed to be those of a 27-year-old man from West Germany who disappeared during a multi-day mountaineering trip nearly 40 years ago, park officials said Thursday.

The remains were found in August 2020 but weren't tentatively declared those of Rudi Moder until Thursday, CBS Denver explains.

Moder, an experienced winter mountaineer who was living in Fort Collins, Colorado, started his excursion over Thunder Pass and into the park on Feb. 13, 1983. His roommate reported him overdue Feb. 19, 1983.
