The shooting occurred around 10 a.M. Yesterday in Lorain, about 48 kilometers west of Cleveland. Police say the two children were playing alone in a bedroom when the boy found a loaded .40-caliber 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.
Police Capt. Roger Watkins says the investigation will be turned over to a county prosecutor's office to determine if criminal charges will be filed.
