What is currently reported
Emergency services responded shortly after 05:00 on 13 October 2026 to a domestic fire at Birch Avenue in the Birchwood area of Waterford City. In a public statement, An Garda Siochana said two adults and two children died. Two other children were admitted to Children’s Health Ireland at Crumlin with critical injuries at the time of the statement.
Gardaí said they had opened a murder investigation into what they described as an arson attack. The residence was declared a crime scene for technical examination, and the coroner and State Pathologist were notified. These facts establish the status of an investigation, not the identity of any person responsible, a motive, or a final account of how the fire started.
Fire-safety lessons that do not depend on the investigation
- If a fire or heavy smoke is detected, alert everyone, leave by the safest available route and call 112/999 from a safe place.
- Do not use lifts in a building fire. Close doors behind you only when doing so does not delay escape.
- If smoke blocks the escape route, do not force your way through it. Move to a safer room or balcony where possible, close the door, call emergency services and make your location visible.
- Do not re-enter a burning or smoke-affected home for possessions.
- Neighbours can call emergency services, avoid obstructing access, and share only observed information with responders; do not attempt a rescue that places additional people in immediate danger.
