Summary

In a murder trial in the Central Criminal Court, a 32‑year‑old man named Niall Stapleton pleaded not guilty to the killing of his 51‑year‑old mother, Siobhan Stapleton, who died on 25 May 2012 from blunt force trauma to the head after being beaten with a garden fork handle. Stapleton, a college graduate with schizophrenia, claimed he believed his mother had been replaced by an impostor. Dr Stephen Monks, a forensic psychiatrist, testified for the defence, stating that Stapleton was suffering from a mental disorder at the time of the killing, had active symptoms of schizophrenia, and did not understand the nature or wrongness of his act. Monks argued that Stapleton met the criteria for a not‑guilty‑by‑reason‑of‑insanity verdict and recommended he remain at the Central Mental Hospital. The trial continues before Mr Justice Garret Sheehan. Niall Stapleton was found not guilty by reason of insanity.
