Killer Clues: Forensics is a true crime series where the smallest piece of evidence cracks the most baffling cases. Each episode follows a single murder investigation and the forensic breakthrough, from DNA and genetic genealogy to digital footprints, cell records, and trace evidence, that turns an unsolvable case into an airtight conviction. The series shows how science speaks for victims who can no longer speak for themselves, proving that no matter how careful the killer, the evidence always remembers.
