Police claim Charles Johnston, 63, shot a nurse, with whom he was said to hold a grudge, and two other men Thursday at Doctors Hospital, the Columbus Ledger-Enquirer reported. The nurse had reportedly treated Johnston's mother before she died in 2004.

Two of the men, the nurse and an administrative assistant, were shot inside the hospital while the third, identified as a truck driver, was shot in the hospital parking lot as the suspect left the hospital.

Police shot and wounded Johnston outside the hospital as the suspect fled the shooting scene. He has since been released from the hospital and was in police custody, the Ledger-Enquirer said.
