FORT WAYNE, Ind. (AP) — Authorities say a weekend shooting that wounded a woman and a boy happened accidentally after children found a loaded gun at a northeastern Indiana home and it went off.

Fort Wayne police say officers called to the home Sunday morning found the 24-year-old woman and the boy inside with single gunshot wounds. They were hospitalized in critical condition, but the woman’s condition was upgraded to stable condition Monday.

Police say a shot struck the boy and went through his body before hitting the woman, who was asleep on a couch. The child was initially listed as being 5 years old, but police later said he was 4.

The shooting is under investigation. Police say people need to make sure guns are properly stored to prevent such accidental shootings.
