CINCINNATI (AP) -- Police in Cincinnati say they have questioned and released an 11-year-old boy who they believe fatally shot a 7-year-old neighbor. Authorities say the younger boy died Friday after being shot with a rifle in the basement playroom of his home. No charges have been filed. Police Sgt. Gary Connor said police are investigating the death as a negligent homicide. Two other children and an adult were in the home at the time. Connor says the 11-year-old is in a nurse's care because he has severe physical disabilities and needs access to medical equipment. Police are not disclosing his name. Connor says the 11-year-old appeared to be open and honest while talking with police in the company of his mother.
