A Mansfield man hunting last weekend at a state park in Alaska was attacked and killed by a grizzly bear. 22-year old Austin Pfeiffer died in the attack Sunday, just two days before his birthday. Pfeiffer was at the park with two other Ohio men hunting for moose, and was attacked by the bear while he was field-dressing a moose that he had just killed.  The National Parks Service says his death is first-known bear mauling fatality at that park since it was established in 1980.
