Rescue crews search for former Navy SEAL after half-brother found dead in Yellowstone National Park

Rescue crews in Yellowstone National Park recovered the body of a 67-year-old Washington state man and searched around a lake Tuesday for his half-brother after the pair failed to return from a backcountry canoe trip.

A 10-person ground crew was walking the shoreline of Shoshone Lake looking for Kim Crumbo, a 74-year-old former Navy SEAL from Ogden, Utah, Yellowstone officials said. A helicopter from nearby Grand Teton National Park was helping in the effort.

Rescuers found the body of Mark O'Neill of Chimacum, Washington, on Monday along the eastern shore, where a canoe, paddle, flotation device and other items were found Sunday. A vacant campsite was found on the south side of the lake.
