On October 23, 1982, O'Neill suffered a gunshot wound in her home on McClain Street in Bedford, New York. Police officers who interviewed O'Neill determined that she had accidentally shot herself in the abdomen with a .38 caliber revolver at her 30-acre, 25-room French-style estate while trying to determine if the weapon was loaded. Her husband at the time (fifth), John Lederer, was not in the house when the handgun was discharged, but two other people were in the house. Detective Sgt. Thomas Rothwell was quoted as having said that O'Neill "didn't know much about guns."
