Jury unanimously convicts Valerie French Kilroy's husband of murder, rejecting insanity defence

A jury at the Central Criminal Court has unanimously convicted James Kilroy of the murder of his wife, Valerie French Kilroy, at their home in Kilbree Lower, Westport, County Mayo, in June 2019. The conviction marks the conclusion of his third trial since 2021, with previous proceedings having collapsed due to unforeseen difficulties. Kilroy had mounted an insanity defence, claiming he was suffering cannabis-induced psychosis when he fatally beat, stabbed and strangled his wife. The jury of eight women and four men rejected this claim after deliberating for approximately two hours. Expert psychiatric evidence was divided on whether cannabis-induced psychosis constitutes a valid defence under the Criminal Law (Insanity) Act, though the prosecution's consultant psychiatrist argued such conditions fall within the definition of intoxication rather than mental disorder. Mr Justice Tony Hunt, presiding, stated the verdict represented the correct outcome, noting that self-induced scenarios cannot serve as defences. Kilroy will receive the mandatory life sentence at sentencing on the following Monday, when the victim's family will be afforded the opportunity to address the court.
