Podcast revisits 2017 death of Joe Deacy in Mayo

Joe Deacy, a 21-year-old man from London of Mayo descent, was found unconscious outside a house at Gortnasillagh, near Swinford, Co. Mayo, in the early morning of 12 August 2017. He had serious head injuries from blunt force trauma and died the following evening in Beaumont Hospital, Dublin. Gardaí first treated the incident as an accident, then upgraded it to a murder investigation, and no arrests or charges have been reported. An RTÉ podcast published on 14 August 2026, nine years after his death, revisited the case, and gardaí said they believe the key to solving it lies within the local community.
