Green Valley Fire says the man was target shooting in a desert area when the 3-year-old accidentally shot him with a .22-caliber gun. Authorities did not elaborate on how it happened.
The father drove himself to the area of the Canoa Road Exit on Interstate 19 and contacted 911 for help. An ambulance took him to the University of Arizona Medical Center, where he was treated for non-life threatening injuries.
The 3-year-old was not injured, Green Valley Fire says.
