Search for missing man in Yellowstone moves from rescue to recovery

MAMMOTH HOT SPRINGS, Wyo. — After five days of searching, efforts to locate Kim Crumbo at Shoshone Lake in Yellowstone National Park transition from rescue to recovery today, Sept. 24, announced Yellowstone National Park in a press release.

Over the past five days, crews swept all the trails in the area, searched the entire Shoshone Lake shoreline by boat and gridded the open water by helicopter. They did not find Crumbo.

Today, crews from the National Park Service’s Submerged Research Center will begin using sonar equipment to detect clues in the water. Park search crews continue to search for Crumbo by foot and boat, with assistance from Grand Teton National Park’s interagency helicopter. Recovery efforts will continue for the next several days as conditions warrant.

Crumbo, 74, and his half-brother Mark O’Neill, 67, were reported overdue by a family member on Sunday, Sept. 19 from their four-night backcountry trip to Shoshone Lake. Yellowstone National Park search and rescue crews located O’Neill’s body along the east shore of Shoshone Lake in Yellowstone National Park Monday, Sept. 20.

Both O’Neill and Crumbo are National Park Service (NPS) retirees, and Crumbo is a former Navy Seal.

This incident remains under investigation. “While we cannot comment further about the specifics of this investigation, we will provide updates when appropriate to do so,” the park said.

“If you have information that could help investigators piece together a timeline of events, or if you were in the Shoshone Lake area between Sept. 12-19, please contact us, if you have not already, at 307-344-2428 or”

“A sincere thank you to the public who have expressed interest in assisting with the search. We ask the public to maintain distance from any law enforcement personnel and search crews, equipment, vehicles and their related activity for the safety of the public in this remote area and to protect the integrity of our work,” Yellowstone said.
