When all other avenues of investigation have been exhausted, cold case detectives turn to cutting edge science: forensic investigative genetic genealogy. This new technique is unlocking seemingly impossible cold cases, often bringing conclusions decades after the crime took place. Criminals who have hidden in the shadows for years find there’s no escaping advancements in forensic science and their own family tree DNA. Using interviews with investigators, forensic scientists, family members of murder victims, crime journalists and more, Bloodline Detectives tells the story of how this new tool is revolutionising cold case crimes. Supplemented with archival material from the case and reconstructions of the crime scene, this series will appeal to all those with a passion for true crime.
Weeknights at 20:00 from 12th February until 8th March.
