In 1988, Lorraine Benson disappeared on her way home from a Christmas party in South West London. At first, her parents hung on to hope that she would return unharmed, but when police discover a discarded earring Lorraine’s mother gave to her, the tragic truth soon comes to light. Someone is reported missing every 90 seconds. Each episode of When Missing Turns to Murder features one case as it reveals powerful and emotional testimony from families and friends of those who have disappeared. Every story intimately shares the moment when a family changes forever – when a missing persons enquiry turns into a murder investigation. As each programme unfolds police and authorities investigate and bring the perpetrators to justice.
