The family of a woman who was murdered alongside her two daughters on Christmas Day have said they feel “retraumatised” by the prospect that the killer could be released within months.

Sharon Whelan (30) and her daughters Zara (seven) and two-year-old Nadia were killed by postman Brian Hennessy at their home in Windgap, Co Kilkenny, in 2008.
