'Life has been hell' sister of murdered IRA victim speaks for the first time

Winston Cross was 18 years old and was about to start a new life in the army when in 1974 his life was cut short. He was abducted, tortured for three days in Donegal before being shot by the IRA along with his friend Joseph Slater. His parents were later told it was a case of mistaken identity. Until now his family have never talked publicly about his murder or the devastating impact it had on their family. His only sister Sharon Austin has now for the first time told how their family fell apart. She details it all in a new book - Beyond the Silence - which features the stories of 28 women from Derry who lost loved ones during the Troubles or suffered in other ways.Enda McClafferty has been speaking to Sharon and she begins by talking about the moment she learned her brother was murdered.
