Ranger finds 'partially consumed' body of hiker in Yellowstone National Park

A hiker in Yellowstone National Park was killed by a grizzly bear sometime last week, the National Park Service says.

The man, whose name has not been released, was an experienced hiker who worked in urgent care clinics inside Yellowstone. An initial investigation has found that he had what appeared to be defensive wounds on his arms, NBC News reports, but an exact cause of death is unknown. A ranger found his "partially consumed" body near the Elephant Back Loop Trail on Friday. That trail is currently closed.

The National Park Service said based on "partial tracks found at the scene," it appears an "adult female grizzly and at least one cub-of-the-year were present and likely involved in the incident." Wildlife biologists have set up traps in the area, and any bears who are found to have participated in the attack will be euthanized.
