Galway court reserves decision on rape and murder DNA retest

Siobhán Hynes, 17, was raped and killed in the early hours of 6 December 1998 at Tismeáin beach near Leitir Mór, Conamara, Galway. John McDonagh, then 27, was convicted of her rape and murder by a Central Criminal Court jury in 2001 and sentenced to life in prison. He lost an appeal in 2007 and a legal challenge in 2015 seeking access to forensic samples. In December 2025 the Court of Appeal heard his application to retest trial exhibits for DNA, with the State arguing that advances in DNA science alone do not justify re-examination. The three-judge court reserved its decision.
