Kate Morgan’s daughter, Lona, died after her friend Ian Edwards lost control of the car they were travelling in. He was found guilty of causing death by dangerous driving and was sentenced to three years and nine months in prison. “I was pleased that he’d got some sort of punishment but the length of the prison term didn’t matter to me. Twelve days or twelve years, it wouldn’t bring Lona back. Over the next few weeks I realised I still had questions I wanted answers to.”

John Mcgowan is the head porter at Durham Cathedral. He lives on site. One night in November 2013 he became aware of noise on the roof of the Chapter House. He went to investigate and saw that four people had climbed up some scaffolding and were putting themselves in much danger as the roof is very high and there is a steep drop into the river at one side.
