Victoria Derbyshire speaks to Penny and John Clough, the parents of a nurse murdered by her former boyfriend whilst he was out on bail. In October, Jonathan Vass was sentenced to a minimum 30 years in jail for stabbing Jane Clough - the mother of his child - to death. He killed her to stop her giving evidence against him after she filed rape charges against him. Her parents, Penny and John, tell Victoria Derbyshire about the anger they feel towards the legal system that they say let their daughter down.
