About Kim Crumbo's case

Primary Source: New York Post

According to the New York Post, Search crews in Yellowstone National Park are looking for an ex-Navy SEAL described as a “monumental hero” who vanished during a canoe trip with his half-brother, who was found dead, officials said. Kim Crumbo, a 74-year-old Navy SEAL veteran who served two tours in Vietnam, was still missing Wednesday, September 22, 2021, after he never returned with his half-brother from their four-night trip on Shoshone Lake in Wyoming, park officials said. Rescuers on Monday, September 20, found the body of his brother, Mark O’Neill of Chimacum, Washington, along the eastern shore. O’Neill likely drowned, but an official cause of death has not been determined, park spokeswoman Morgan Warthin said. Near where his body was found, crews located a canoe, paddle, flotation device and other items, officials said. A vacant campsite was also located on the south side of the lake, which can be subject to high winds and sudden storms. A relative had reported the two experienced boaters missing Sunday when it became apparent they were overdue from their backcountry canoe trip. Both of the men had previously worked at Arizona’s Grand Canyon National Park in various capacities, including as river rangers, park officials said. Crumbo had co-founded the conservation group Grand Canyon Wildlands Council, which later joined forces with another group to form Wild Arizona. His colleague Kelly Burke said those who know Crumbo have been reconnecting over his disappearance “to hold each other up and put that energy in leaving the door open for him to walk back in.” “It’s Kim Crumbo, after all,” she said. “He’s a monumental hero and legend of a man. We can’t bring ourselves to believe he wouldn’t emerge from this.”
