The DNA mistake that let a killer walk free for 12 years | Forensic Investigators

A 15-year-old girl is brutally murdered and left near a stormwater drain. With no DNA technology available at the time, investigators are forced to rely on blood types, witness accounts and forensic clues to find her killer. Lloyd Clarke Fletcher becomes a prime suspect, but an early DNA test appears to clear him. Twelve years later, a horrific attack on another young woman leads police back to Fletcher — and a second DNA test finally reveals the truth. A chilling case that shows how forensic science can solve crimes long after they were committed. #ForensicInvestigators #TrueCrime #DNA #ColdCase #AustralianTrueCrime
