An investigation continues after a Saint Joseph man accidentally shot his 11-year-old son in the face while they were discussing gun safety. The boy was taken to Heartland with serious injuries and was then flown to Children’s Mercy Hospital for treatment. Police say the father and son were cleaning guns and planning a hunting trip when a weapon went off. The bullet struck the boy in the cheek and lodged below his jaw. Police may present evidence to the prosecuting attorney this week for possible charges.
