MISSION (AP) – A 3-year-old boy is in critical condition after being shot in an apartment in northeast Kansas’ Johnson County.

KSHB-TV 41 reports that the child was taken to Children’s Mercy Hospital after he was wounded Thursday afternoon with a 9 millimeter handgun.

Mission police believe a single bullet went through the boy’s left arm and hit his abdomen.

The boy was at home with his father, the father’s roommate and the roommate’s fiance at the time. Police said the gun was “out and available.”
