Upper Peninsula authorities are investigating the accidental shooting of a man who was in the woods with his 3-year-old son.

A Houghton County sheriff's department news release says 37-year-old Albert Miller of Chassell Township was with his son, Adam, when the boy fell and caused Miller's .22-caliber weapon to fire.

WLUC-TV says a bullet penetrated Miller's lung. He underwent surgery and was in stable condition at Portage Health System.

The shooting happened Saturday in Chassell Township.
