An autopsy report released Thursday for a man shot and killed while camping with his family says he was struck in the back. Glenn Martin, 60, of Palmer Lake, was killed July 3 when he was struck by an apparently errant bullet in the Rainbow Falls area of the Pike National Forest, between Woodland Park and Deckers in Douglas County. The single bullet struck Martin in the back and traveled diagonally, striking his left lung and aorta, according to a report from the Douglas County Coroner's Office.
