John McDonagh's Court of Appeal bid to retest forensic evidence in Siobhan Hynes murder case

John McDonagh, 51, was found guilty in 2001 by a Central Criminal Court jury of the rape and murder of 17-year-old Siobhan Hynes, who was killed at Tismeain beach in Keeraunbeg, Connemara, Galway, in the early hours of 6 December 1998. He was sentenced to life in prison. In 2007 an attempt to introduce new evidence was refused by the courts. In December 2025 the Court of Appeal heard McDonagh's application to retest forensic fibre evidence, with the defence arguing his conviction was a miscarriage of justice and the State opposing the retests; the matter was to continue the following Tuesday.
