Melanie Road, 17, was murdered on her way home from a nightclub in Bath in 1984. She had been out with her boyfriend and friends, but Melanie had been sexually assaulted and brutally stabbed 26 times on her way back home. A milkman found her body the following day. After multiple lines of enquiries and arrests, the police weren't able to find the killer, and despite recovering a large amount of DNA evidence at the scene, the case went cold.

The real breakthrough came in 2014 when the DNA database returned a familial match, leading the police to married father Christopher Hampton. This man had brutally murdered Melanie on the night in 1984 and had been at large for 30 years.
