After shooting the victims in the head, the killer staged the scene, placed the incriminating evidence into a plastic bag, and tossed it into the river.

A human skeleton was discovered in the North Carolina marshlands. When investigators learned she'd been dead for 18 months, they knew it would be difficult to find out who she was, much less who killed her.

When two women went missing and were later found brutally murdered, police wondered if they were victims of a hate crime.

A young, attractive hairdresser was sexually assaulted and murdered in her own beauty salon. The evidence at the crime scene didn't match any of the suspects, and, after the initial investigation, the case went cold for ten years.

The killer probably hoped to cover their tracks by staging the crime scene. But investigators saw through the attempt almost immediately and turned to forensic science to learn what really happened that night.

A woman was brutally murdered in her home, and the only witnesses to the crime were the family dogs. An expert in canine behavior was convinced the killer knew both the victim and the animals, and he was determined to find out what the dogs had seen.

After the suspect was convicted of arson and murder, he maintained his innocence but was sentenced to 25 years in prison. He turned to the law books in the prison library and watched TV about forensic science, and set out to prove his innocence.

Tests reveal the race, eye color and hair color of the person responsible for killing two young women on Halloween night.

The only lead to finding a serial killer on the loose is a bloody fingerprint on the body of a victim.
