Men Presumed Dead on Crashed Plane In Wyoming

CODY, Wyo. -- Authorities say two elderly brothers on board a single-engine plane found crashed on a mountain in northwest Wyoming are presumed dead.

The Park County Sheriff Office says the determination was made after viewing the crash site from the air. The danger of avalanche made it too risky to put people on the rugged, snowy mountain just outside Yellowstone National Park. The 1963 Mooney M20C was last seen May 6 departing Yellowstone Regional Airport in Cody.

On board were 84-year-old Robert L. Zimmerman of Huntsville, Alabama, and 86-year-old Ward H. Zimmerman of Seattle. The plane was reported missing Saturday and was found Monday at about 9,900-foot elevation on a 60-degree slope with a large cornice above it. The brothers were headed from Cody to Twin Falls, Idaho, and then to Seattle.
