New unsolved murder evidence by July

GARDAÍ conducting a forensic ‘cold case’ review of the 1997 Grangegorman murders, which were never solved, expect to have preliminary findings by the end of July.

They hope there will be sufficient new evidence gleaned to bring charges against the principal suspect, Mark Nash, who is already serving a life sentence for the murder of two people in Roscommon later that same year.

Sylvia Shields, 59, and Mary Callinan, 61, both patients of St Brendan’s Psychiatric Hospital in Grangegorman, Dublin, were murdered on the night of March 6 to 7, 1997. Up to 30 stab wounds were found on each of their bodies.
