The family of a murdered woman has spoken of the “mental torture” after prison authorities — unknown to the family — granted temporary release to their mother’s killer, and then revoked it after they went public to protest against the decision.

Ronan Quinn said his family had gone through “enough trauma” since his mother, Christine, was stabbed 35 times by Mark Costigan at her home in Kilkenny in December 2002.
