Overview: In central Newcastle, a teenage girl has been raped by a stranger in a local park. It is the job of Northumbria Police's head of forensics Kirsty Potter and senior investigating officer Shelley Hudson to find the unknown suspect and put him behind bars as quickly as possible. With every hour that passes the chances of obtaining forensic evidence reduce and intimate forensic samples from the teenager who has been raped are fast-tracked to a specialist lab in order to try and identify the suspect. A scour of local CCTV identifies a man wearing the same distinctive jacket as the teenager described. Alongside the traditional forensic search for body fluids, DNA and fibres, the police also deploy the rapidly evolving skills of their digital forensic team. Criminals may think they can withhold passwords and delete incriminating search histories from their computers, tablets and smart phones, but it won’t give head of digital media Jerry Hewitt and his team too much difficulty.
