Andy Cash marks four years since stabbing three siblings to death in Tallaght
In the early hours of 4 September 2022, Andy Cash, 30, stabbed his three younger siblings hundreds of times at their home on Rossfield Avenue, Tallaght, Dublin, killing 18-year-old Lisa Cash and eight-year-old twins Chelsea and Christy Cawley. Cash had been at a family event before taking a taxi to the house, where he stabbed Lisa 71 times, Chelsea 65 times, and Christy 107 times before throwing Christy from a first-floor window. He left the house, told the taxi driver to call 999, then returned inside. Cash pleaded guilty to three murder charges in May 2024 and was sentenced to three life sentences, and is serving his sentence in Portlaoise Prison. The four-year anniversary of the killings was marked in September 2026 with floral tributes at the victims' graves.
