Grangegorman: ‘Most horrific crime scene’

A lead investigator in the 1997 murders of two psychiatric patients by serial killer Mark Nash said it was the “most horrific crime scene” he ever witnessed.

Retired detective sergeant Alan Bailey said it was something that would stay with him for the rest of his life.

Sylvia Shields, 59, and Mary Callinan, 61, were found stabbed to death at their sheltered accommodation in Grangegorman Psychiatric Hospital, Dublin, on March 7, 1997.

Nash is serving a double life sentence for their murders. This is in addition to two other life sentences: for the killing of couple Carl and Catherine Doyle in Roscommon in August 1997.

The Grangegorman murders sparked an inquiry into the garda investigation which resulted in a heroin addict, Dean Lyons, being charged with the women’s murders in July 1997.

Speaking on Today with Sean O’Rourke on RTÉ, Mr Bailey said the day he went to the scene would remain forever with him.
