The woman hadn’t shown up for work in two days, and her boss reported her missing. When her body was found, the evidence pointed to suspects who claimed they had nothing to do with the crime. The victim, herself, would help police to prove they were lying.

The investigation of an exotic dancer’s disappearance led police to an isolated 75-acre site where someone had been shot and cremated.

A young mother is murdered after years of domestic abuse. There are clues at the scene: bloody footprints and DNA from the victim’s rape kit. But the evidence which will conclusively tie the killer to the crime is on a freshly baked hamburger bun.

In the late 1990s, one criminal terrorized an entire community. Witnesses refused to speak out. They knew the consequences could be deadly.

In this special episode, we take a closer look at cases previously featured on this series. Our goal is to explore more fully some of the investigative methods and techniques that have made the FBI the premier law enforcement agency in the world.

A man calls 911 claiming his wife fell down the stairs and died. Rescue workers respond, and do indeed find the woman dead at the base of the stairs. There is a large amount of blood on and around the body. The medical examiner concludes the woman died as a result of a blunt force trauma, and begins the search for a murder weapon. Blood spatter also proves the woman was beaten before she fell, or was placed at the base of the stairs. The man’s prints are found on a champagne bottle, but not the glasses, leading investigators to believe he beat his wife with the bottle. Blood spatter is found on most of the man’s clothing, proving he beat his wife to death.

When a young man confessed to the rape and murder of a woman in a restaurant, police were convinced the case was solved. Eight years later, another man imprisoned for an unrelated crime, admitted HE committed the murder. But authorities viewed that admission as unfounded. They could not understand why an innocent man would confess to a crime he did not commit, and if he were innocent, why he said nothing during his eight years in prison.

When two boys are viciously attacked while fishing in a nearby pond, authorities spring into action. They suspect a group of teenage thugs, but lack solid evidence. It would take the murky waters of a fishing hole to provide clear evidence, and help authorities reel in the boy’s attackers.

The body of a young woman was found in an icy Ohio waterway. She had been strangled to death, and most of the evidence had been washed away by the rushing water. Investigators conducted a painstaking examination of the victim’s body and clothing, and discovered a tiny clue – hardly bigger than a human hair. That clue would enable police to determine where the victim had been just before she died; it would also lead them to her killer.

In a small South Carolina town in 1991, 17-year-old Crystal Faye Todd, a popular high school student, was raped and murdered.

When his DNA matched semen at the crime scene, he couldn’t believe it. Neither could his mother, his girlfriend – and even Crystal’s mother. Ken had a solid alibi for the night of the murder, and he asked a question no one could answer: “If I had killed her, why would I have given blood?”
