Episode 2

With suspects under attack, Karen’s cold case review has just become a live investigation overnight. But is the perpetrator Rosie’s killer, out to silence potential snitches? Or are they a wounded family member or friend, out to exact revenge? Finding the answer could give Karen her strongest hope yet of solving the case. In 1996, the discovery of an abandoned car leads to the arrest of one of the students, but with a lack of physical evidence, the investigation founders – until a potential eye witness brings DI Maclennan new hope. Exploiting the contacts of her best friend River in the hope of finding out more about a suspicious ex-partner of Rosie’s, Karen makes a shocking discovery.
