A man has pleaded not guilty to murdering two women in sheltered accommodation in Grangegorman 18 years ago.

Mark Nash, with addresses at Prussia Street and Clonliffe Road in Dublin, will go on trial at the Central Criminal Court this Wednesday for the killings of Sylvia Shields and Mary Callinan in March 1997.

The two women were living in sheltered accommodation attached to St Brendan's Hospital in Grangegorman in Dublin.

The jury has been told they will hear references to a man named Dean Lyons - who has since died - and to Catherine and Carl Doyle who died in Roscommon, as well as a Sarah-Jane Doyle.
