Anniversary of Harry Dunn's death: 'I won't stop' until Anne Sacoolas goes through UK justice system, says Harry's mother

On the first anniversary of Harry Dunn's death, his mother Charlotte Charles speaks of her determination to bring the suspect to trial in the UK. Anne Sacoolas was charged with causing death by dangerous driving after a crash outside RAF Croughton in Northamptonshire in August last year, which resulted in the 19-year-old's death. She claimed diplomatic immunity and returned to the United States.
