At the time, he had been employed to maintain the home she was killed in, and was the only person to have access as the homeowners lived overseas.Commissioning Editor for the documentary, Emile Nawagamuwa, said: "Leah's disappearance moved the nation. At the heart of this story is a family who have faced unimaginable heartbreak with extraordinary courage."We are privileged that John, Claire and Jade have chosen to share their experience with us for the first time."This is an important and necessary film that not only honours Leah's memory, but also sparks vital conversations about how we ensure tragedies like this never happen again.”Series director, Adam Luria, added: “Leah’s story is one of the most shocking and heart-breaking that the UK has seen in recent years."We’re hoping this documentary will support her parents, John and Claire, and her sister, Jade, as they seek changes to British legislation to ensure something like this can’t happen to another family in the future.”Article continues belowThe coroner had concluded Leah was was most likely the victim of an "unwarranted sex attack" but the exact cause of her death could not be determined.Her remains had been discovered in plastic bags in the loft of a property on Loxbeare Drive after a handyman visited the property, tasked with eradicating a nasty smell.The Search for Leah Croucher: A Parent’s Nightmare is in production and will be available to stream on U and U&W in 2026.
