The murder of 18-year-old Louise Smith rocked the city of Bristol, after she disappeared on Christmas Eve in 1995. Over 3000 people were tested to see if they matched DNA found on Louise. But when they get a hit, a student called David Frost, the police find out they can't arrest him as he had flown all the way to South Africa. Murdertown puts location centre stage. Each episode tells the compelling, step-by-step story of how one extraordinary murder was solved and how it fit a disturbing wider pattern in one particular city. With interviews from victims, witnesses and police officers, Murdertown tells the story of some of the most shocking murders in the UK and examines the impact they had on local communities around them.
