A hiker was killed by a grizzly bear in Yellowstone National Park last week, the National Parks Service said a preliminary investigation had found.

Although an exact cause of death was yet to be determined, the service said investigators had identified what appeared to be defensive wounds on the man’s arms.

It said the victim had been found “partially consumed” in the vicinity of the Elephant Black Loop Trail, near Lake Village, on Friday afternoon.

“Based on partial tracks found at the scene, it appears that an adult female grizzly and at least one cub-of-the-year were present and likely involved in the incident,” the National Parks Service said in a statement.
