This episode travels to Tunbridge Wells to investigate the shocking murder of Terry Edmonds. Seventeen-year-old Terry travelled to Tunbridge to visit friends when she disappeared. But 12 days later, her body was discovered, stuffed into a suitcase and abandoned in a multi-storey car park. A blood pattern analyst, Jo Millington, was called on by police to help the investigation. Complex DNA results led to two hung juries. When the time comes for a third trial, Jo is determined to do all she can to counter the suspect's defence and discover if a blood stain on their clothing was made at the time of the murder or afterwards. Through many experiments, Jo is able to place the suspect at the crime scene close to the time of the murder. The killer is convicted at the third trial and sentenced to life in prison. With insightful interviews from Jo Millington and retired chief superintendent Paul Dockley. In November 2020, in Horley, the body of 62-year-old Nigel Chapman is discovered in his bedroom, stabbed to death. Police are sure the murderer had attempted to clean up the crime scene, and a search of a nearby river uncovers blood-stained clothing concealed in a bin bag. Detectives reach out to forensic search specialist Peter Faulding to look for items missing from Nigel's home and anything else that may be related to the crime. Peter uncovers crucial evidence that helps police convict Nigel's friend, Jennifer Lloyd, of the murder.
