This episode of Radio 4's Woman's Hour series looks at how the Yorkshire Ripper's crimes affected the 25 children he left motherless. Almost 30 years ago, a young woman went missing in the early hours of the morning. When they found her body, only yards away from the house where her four young children had been sleeping, the police were yet to realise they had a serial killer in their midst. Wilma McCann was the first victim of Peter Sutcliffe who became known as the Yorkshire Ripper. Her son, Richard, explains how the loss of his mother and the media's obsession with the Ripper killings affected his life.
