A Yellowstone National Park hiker whose body was found last week was mauled and killed by a grizzly bear, authorities confirmed Monday.
The hiker was identified as 59-year-old John Wallace of Chassell, Mich. He was traveling alone and had pitched his tent in a campground along the Mary Mountain Trail on Wednesday.
His body was discovered Friday morning by two hikers. An autopsy conducted on Sunday confirmed that Wallace died of traumatic injuries from a bear attack.
