Judge Rinder's Crime Stories S06E01 - Nova Welsh

The barrister examines more real-life cases, beginning with the death of Nova Welsh, who was found dead in a cupboard at her home in Birmingham in 1981, but no one was convicted. Thirty-five years later police decided to look again at the old evidence and hoped DNA from a piece of chewing gum left at the scene would help them finally catch up with the killer.
