Isabelle, the wolf that last month crossed a perilous ice bridge between Isle Royale and the mainland, was as unlucky in death as she was in love.
National Park officials on Friday said that an investigation found she was killed with a tiny, low-velocity air gun pellet more suitable for squirrels than wolves that slipped between her ribs and hit an artery. After finding her way across 20 miles of ice, she bled to death on the Grand Portage Indian Reservation at the edge of Lake Superior in the northeast corner of Minnesota.
