Man found not guilty of murdering his mother by reason of insanity

Summary

A 32‑year‑old man with schizophrenia, Niall Stapleton, was found not guilty of murdering his 51‑year‑old mother, Siobhan Stapleton, by reason of insanity. The murder took place on 25 May 2012 at their home in Kilfane, Thomastown, Co. Kilkenny, when the mother was struck on the head with the handle of a garden implement, resulting in blunt‑force trauma. Stapleton admitted causing the death but claimed he believed his mother had been replaced by an impostor. Forensic psychiatrists for both sides agreed he met the legal requirement for a special verdict of not guilty by reason of insanity. A jury of seven men and five women deliberated for over two hours before reaching that verdict. The case is scheduled to return to the judge for a further committal order.
