A father was killed and his son severely injured when a tree toppled by a powerful storm fell on their tent in a northeastern Minnesota forest this weekend, according to sheriff's officials. The father and teenage son were camping at Duncan Lake with another man and his son on Father's Day in the Boundary Waters Canoe Area Wilderness in the Superior National Forest about 10:30 p.m. Sunday when the storm began, according to the Cook County Sheriff's Office. A second emergency call at about the same time involved a man camping on Clove Lake who had also been injured by a falling tree, according to Cook County sheriff's officials. The injured boy was taken to a hospital and then airlifted to Duluth; there was no immediate word on his condition. In St. Louis County, three people with the outdoor education program Outward Bound were injured in an indirect lightning strike near Crooked Lake, according to the sheriff's department.
