Forensics: The Real CSI

A 34-year-old man is fatally stabbed as he visits a group of friends who are socialising in one of the bedrooms of a multi-occupancy property in Birmingham. With vital evidence compromised during the attempts by paramedics to save his life, detectives use CCTV and financial transactions to track their suspect and apprehend him just before he boards an international flight out of the country. The forensic team employ a mixture of traditional and digital methods to try to determine whether or not the witnesses are telling the truth.
