This week, we take a look at the legacy of one of Ireland's most gruesome gangs of serial killers: the Shankill Butchers. Cliodhna Morrissey's grandfather, Joseph, was murdered by a gang of UVF killers in February 1977. Her father, Paul, identified the remains of his father. He was never the same again. Cliodhna speaks about the knock-on effect that affected the grandchildren who still live with the death of both their father and grandfather today.
