Our first case delves into the gripping investigation of the 2004 murder of 37-year-old David Morley, who was brutally attacked by a gang of youths on a chilling spree of random, unprovoked violence along London’s South Bank. \n\nDetective Nick Scola leads the case, meticulously analysing CCTV footage to trace the gang’s trail as they prowled the streets for their next victim. Although surveillance offers crucial glimpses into the night’s events, hard evidence remains elusive, leaving investigators at a standstill. \n\nKey footage is discovered showing the suspects' hands pressed against a metal door during one attack, but police are presented with a frustrating obstacle as extracting fingerprints proves challenging. In a breakthrough moment, crime scene manager Callum Sutherland and his forensic team devise a bold approach: building and using their own superglue gas chamber to lift the difficult fingerprints from the scene. This innovative method provides the damning evidence needed to finally identify the suspects and bring them to justice. With revealing interviews from retired officer Nick Scola, Callum Sutherland and news reporter Ronke Phillips. \n\nOur second investigation is a very different type of case... Expert witnesses help solve all types of crime, not just violent ones. Where there’s money to be made, criminals will stop at nothing to deceive and defraud their victims. And in the world of celebrity memorabilia, the stakes are high. So when officers become suspicious about one prolific seller of signatures of famous footballers, they need an expert with a very special skill to help. Autograph analyst Garry King proves the signatures are fraudulent and helps detectives pinpoint the company behind the scam.
