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 murdering his wife Valerie French Kilroy at their home in Kilbree Lower, Westport, County Mayo, in June 2019. The verdict came after the jury of eight women and four men deliberated for approximately two hours, rejecting the defence argument that Kilroy was suffering cannabis-induced psychosis at the time of the killing. The conviction marks the conclusion of proceedings that have spanned three trials since 2021, with two earlier attempts having collapsed owing to unforeseen difficulties. Throughout the trial, Kilroy's defence team called psychiatric experts who concluded he met the legal criteria for a finding of not guilty by reason of insanity, attributing his actions to drug-induced psychosis. The prosecution's consultant psychiatrist disputed this assessment, arguing that cannabis-induced conditions should be classified as intoxication rather than mental disorder under the Criminal Law (Insanity) Act, and therefore cannot constitute a valid legal defence. Mr Justice Tony Hunt, presiding over the trial, instructed the jury to consider the ordinary legal meaning of intoxicating influence in evaluating the insanity defence. Following the conviction, the judge observed that the verdict accorded with established legislative policy, noting that self-induced circumstances cannot serve as grounds for acquittal on grounds of insanity. The evidence presented to the jury indicated that Kilroy caused his wife's death through blunt force trauma, strangulation, and stabbing. A mandatory life sentence was imposed at sentencing proceedings the following Monday, when members of the victim's family were given the opportunity to address the court. In October 2024, Kilroy was granted legal aid by the Court of Appeal to pursue an appeal of his conviction, with funding provided for two counsel to act on his behalf.
