A 4-year-old boy was in a pick-up truck with his father, 29-year-old Christopher Upenieks, of Mason City, Iowa, when the boy picked up a handgun and fired it. The bullet hit Upenieks in the knee.
When police arrived the two were in the parked truck outside their home. Upenieks was taken to the hospital and treated for non-life threatening injuries.
Upenieks, who has a concealed weapons permit, has been charged with child endangerment and allowing a minor access to a firearm for leaving a loaded, unsecured firearm where the child could access it.
