LORAIN, OHIO—Police say a 3-year-old Ohio girl is in critical condition after being shot in the head by her 4-year-old brother, who found a gun in a dresser.

The shooting occurred around 10 a.m. Sunday in Lorain, about 50 km west of Cleveland. Police say the two children were playing alone in a bedroom when the boy found a loaded .40-calibre handgun.

A police report says the father of the 3-year-old girl was holding her in his arms when officers arrived. The report says the 4-year-old boy was crying and that he repeatedly told an officer he was sorry.

Lorain police Capt. Roger Watkins says the investigation will be turned over to the Lorain County prosecutor’s office to determine if criminal charges will be filed.
