Calm Nash pictured hours before killings
This is the final picture of serial killer Mark Nash enjoying a table quiz - just hours before he carried out a gruesome double murder.
Nash stabbed and mutilated Sylvia Sheils and Mary Callanan at their sheltered accommodation in Grangegorman, Dublin, later that night in March 1997.
In the picture obtained by RTE, he is surrounded by people and looking relaxed at the table quiz in the GPO.
Hanging on his chair is his black velvet jacket, which would retain crucial DNA evidence that would lead to his eventual conviction.
Only a matter of hours after the table quiz ended, he wore the same jacket as he stabbed Sylvia shield and Mary to death.
For years it retained the DNA of both victims - but it would be over a decade until advances in forensic science indicated the presence of the DNA of both murder victims.
On Monday a Central Criminal Court jury took just over four hours to unanimously find Nash guilty of the murders.
Nash was already in jail for killing Catherine and Carl Doyle at their home in Castlerea, Co Roscommon, in August 1997.
