Summary

Mark Nash has been found guilty of murdering two women at sheltered accommodation in Grangegorman, Dublin, in March 1997. A Central Criminal Court jury returned a unanimous verdict after deliberating for over four hours on Monday, 20 April 2015. The trial lasted 48 days, during which 71 witnesses gave evidence. Nash, 42, originally from England with Dublin addresses, had pleaded not guilty to the murders of Sylvia Sheils, aged 59, and Mary Callanan, aged 61. The prosecution's case rested on admissions made by Nash, forensic evidence including DNA found on his jacket, and a caterpillar boot print discovered at the scene. Nash is already serving a life sentence for murders committed in Ballintober, Castlerea, County Roscommon, in August 1997. Mr Justice Carroll Moran imposed a life sentence for the Grangegorman murders. The case had remained unsolved for eighteen years before a DNA breakthrough in 2009 led to Nash's formal charging in October of that year.
