Taoiseach Enda Kenny has given a commitment to meet with Mary Boyle's Twin sister Ann Doherty.
Mary Boyle disappeared from her grandparent's farm at Cashelard near Ballyshannon on the 18th of March 1977. It is now Ireland's longest running missing person case.
Last week, Ann Doherty visited Pearse Street Garda Station along with the country singer Margo O'Donnell who also made a statement to Gardai alleging the identity of Mary's killer.
Donegal Deputy Pearse Doherty says it's a positive development.......
