Two young women were murdered, one in 1992 and the other ten months later in 1993, and the cases remained unsolved for over twenty years. Police discovered identical DNA on both victims, yet it did not match any known individual in the database.

is a programme presented as a single episode. It's positioned as a documentary‑style investigation that focuses on a cold case that has lingered for decades. The title hints at an attempt to reveal the identity of a perpetrator linked to a series of violent crimes, and the episode structures its narrative around the forensic clues that have emerged over time. The core of the episode centres on two murders of young women that occurred ten months apart, one in 1992 and the other in 1993. Both killings remained unsolved for more than twenty years, leaving families and investigators without closure. Throughout the programme, the audience learns that forensic teams discovered identical DNA material on each victim. Despite this striking connection, the DNA profile didn't match any individual in existing criminal or civilian databases, leaving the case open. The programme highlights the prolonged investigative effort, noting how the identical DNA evidence has both linked the two crimes and simultaneously frustrated attempts to identify the perpetrator. It underscores the challenges faced by law enforcement when a biological trace points to a single unknown source, and you'll see why the murders have persisted as an unresolved mystery despite advances in forensic technology.
