Grizzly Kills Yellowstone Hiker

A preliminary investigation into a hiker's death in Yellowstone National Park suggests the man was attacked by a grizzly bear.

While the exact cause of death has not been determined, investigators identified what appear to be defensive wounds on the victim's forearms, Yellowstone National Park said in a statement Saturday. A forensic autopsy is scheduled for Monday.

The victim, whose name has not been released, was found Friday in a popular off-trail area less than a mile from Elephant Back Loop Trail -- an area he was known to frequent. His body was partially eaten and covered.
