As featured in the BBC drama Four Lives.

On 18 June 2014 Sarah Sak's son, Anthony Walgate, was murdered by serial killer Stephen Port after they met on dating app Grindr. Two years later Stephen Port was sentenced to life imprisonment at the Old Bailey in November 2016. The case received extensive press coverage not only because of the horrific nature of the crimes but also because the police refused to investigate Anthony's death despite three more bodies being found in near identical circumstances. It was not until Scotland Yard's crime squad took over that Stephen Port was arrested, charged, convicted and sentenced to life in prison.

Sarah Sak's courage and perseverance helped to achieve justice for her much-loved son and now she campaigns for better policing, to recognise and link crimes, support families, counter homophobia and raise greater public awareness of the dangers of dating sites/apps, to prevent further deaths.

In A Life Stolen Sarah will tell the story of the murder of her son in full for the first time in an attempt to understand how this happened and what might have been done to prevent it.
