Search underway for former Navy SEAL missing after trip to Yellowstone, brother found dead

A search was underway on Thursday for a former Navy SEAL still missing after a four-day trip to Yellowstone with his brother, who has since been found dead.

Crews this week have been walking the shoreline of Shoshone Lake while a helicopter continues searching from above for Kim Crumbo, a 74-year-old veteran from Utah. Rescuers on Monday found the body of his brother, Mark O’Neill, a Washington resident, in the same area along “with a canoe, paddle, PFD and other personal belongings,” according to a statement from the National Park Services.

He likely drowned but a cause of death has not been released.

Family members reported the men, both retired from the park service, missing on Sunday, when they failed to return from a weekend getaway at the national park.

In addition to his military service, Crumbo spent more than 20 years serving as a river ranger, park ranger and wilderness coordinator in Grand Canyon National Park, The Salt Lake Tribune reported. He is also member of the Potawatomi Tribe and worked “directly with diverse individuals including Navajo, Hopi, Paiute, Havasupai, Hualapai, Zuni, and Ute folks,” according to the Rewilding Institute, a conservation program on which he served as a board member.

John Davis, the executive director of the institute, called Crumbo “one of North America’s strongest wilderness and wildlife advocates for decades.”

He and his brother were last seen alive near Shoshone Lake, which covers 13 square miles and has an average temperature of around 48 degrees, with survival time estimated to be only 20 to 30 minutes in such cold water, officials said. The lake also can be subject to high winds and sudden storms.
