Apr 27, 2005 · 23m

A house erupted in flames on a cold January night, killing one person and injuring another.

It would take a nationally known fire investigator to determine what happened, and who was responsible.

E2. Marked for Life

May 18, 2005 · 23m

In 1957, California police searched for a man who had committed several crimes in one night – including murder, but after following thousands of leads, eventually, the case turns cold.

E3. Plastic Puzzle

Jun 1, 2005 · 23m

Jun 29, 2005 · 23m

When an elderly couple died in a suspicious house fire, their son became the prime suspect. The son insisted he was innocent; he said he tried to extinguish the fire by pouring water on it, but that only made it worse. Investigators turned to forensic science to determine if the fire had been set deliberately, or if it was an unfortunate accident.

E5. Soiled Plan

Jul 6, 2005 · 23m

A mother of two young children went missing and, less than a day later, her body was found.

Twenty years later, advances in technology enabled investigators to see the evidence in a new light, and discover it pointed directly to the killer.

E6. Headquarters

Jul 13, 2005 · 23m

When hunters reported finding a skull in a Texas canyon, police find bits of clothing, a woman's shoe, some small bones and a strand of hair.

Now all they had to do was find her killer.

E7. One for the Road

Jul 20, 2005 · 23m

A married couple decided to escape the cold of winter with a mini-vacation in Key West.

E8. Army of Evidence

Jul 27, 2005 · 23m

A mother of two young children was found dead in her bedroom. It appeared she had killed herself: There were suicide notes near her body, and a pistol was in her hand.

E9. Shear Luck

Aug 3, 2005 · 23m

In 1991, when the wife of a serviceman was brutally murdered in the Philippines, the Air Force Office of Special Investigators swung into action. Clues led to the victim's husband, but he insisted he was innocent. To find out if he was telling the truth, investigators would have to do something unprecedented: Reassemble a 5-1/4 inch computer disk which had been cut to pieces with pinking shears.

E10. Tagging a Suspect

Aug 10, 2005 · 23m

Bombings are difficult to solve, because the perpetrator isn't usually at the scene, and the evidence goes up in smoke. But there are clues if investigators know where to look. In this case pieces of plastic the size of grains of sand, held the key to a man's murder.

E11. Strong Impressions

Aug 17, 2005 · 23m

The wife of an Air Force officer was found dead in her bed, with a plastic laundry bag near her face. At first glance, it appeared she'd been doing laundry, fell asleep, rolled onto the bag, and suffocated. But further investigation proved that the scene had been staged. Her death wasn't an accident; it was cold-blooded murder.

E12. Cereal Killer

Aug 24, 2005 · 23m

When a fire destroyed most of a home and a young boy went missing, police organized the largest search in the history of their small town.

E13. Crash Course

Aug 31, 2005 · 23m

A highway patrolman was dispatched to what he thought would be a routine traffic accident until he looked in the car. While he had no formal training in forensic science, he had seen hundreds of accidents – but never as much blood as this. He was shocked by the coroner's ruling of accidental death, and then an anonymous phone call breathed new life into his investigation.

E14. A Leg Up on Crime

Sep 7, 2005 · 23m

The decomposed body of a young woman was discovered in a Bakersfield irrigation canal. If there was trace evidence, it had been washed away. Another victim was found in that same canal a year later; this time, the perpetrator had been careless. The shoe prints found at the scene would lead police to the most unlikely of killers.

E15. Tight-Fitting Genes

Sep 14, 2005 · 23m

A behavioral profile is helpful in a murder investigation, but it's not a road map to the killer. One such profile caused the Baton Rouge Police Department to search for the wrong man. They might not have made an arrest, had it not been for a DNA picture of the suspect, painted by a molecular biologist. [also marked as S10:E15]

E16. Deadly Valentine

Sep 21, 2005 · 23m

An obstetrician returned home from the hospital and found his wife on the floor of the bathroom. She was covered with blood and not breathing.

His version of events was not supported by the blood spatter evidence, and investigators had to determine why. [also marked as S10:E17]

E17. Picture This

Sep 28, 2005 · 23m

E18. Oily in the Morning

Oct 5, 2005 · 23m

When police recovered the submerged car of a man reported missing, they expected to find his body – but it wasn't there.

The investigation which followed would uncover an obsession turned deadly, and the motive for murder. [also marked as S10:E19]

E19. Gold Rush

Oct 12, 2005 · 23m

Emergency dispatch received a call from a man who said his girlfriend shot and killed herself. Police found the victim in the caller's house, lying in a pool of blood with the gun next to her on the floor. The autopsy revealed that the gunshot wound was not self-inflicted and the evidence found on her body would give police a golden opportunity to catch her killer.

E20. Four on the Floor

Oct 19, 2005 · 23m

A Native American woman was brutally killed in the desert of New Mexico, and the crime scene was rich in forensic evidence: tyre tracks, shoe impressions and even the murder weapons. The site was less than 10 miles from another crime scene where, two years earlier, a male Native American was beaten and stabbed to death. Police began to wonder: was a serial killer on the loose?

E21. Writer's Block

Oct 26, 2005 · 23m

A brilliant young architect became ill and died just before she was to testify in a criminal trial. The autopsy revealed she'd been poisoned with arsenic; it was a slow and painful death, so suicide was unlikely. Investigators had to determine who among her family, friends and business associates had a motive for murder. [also marked as S7:E22]

E22. A Clean Getaway

Nov 2, 2005 · 23m

An employee of a dry cleaner was raped and murdered in the store, and investigators thought themselves fortunate to have two eyewitnesses.

E23. Prints Among Thieves

Nov 9, 2005 · 23m

E24. Unholy Alliance

Nov 16, 2005 · 23m

When a young woman disappeared, police feared she was the latest victim in a string of similar crimes but the MO wasn't quite right. A pair of bloody gloves, unique tire tracks, and ordinary grass and pine needles provided investigators with some extraordinary clues.

E25. Signed, Sealed & Delivered

Nov 23, 2005 · 23m

Two men were convicted of intentionally shooting and killing a passenger in a moving car, their friend was granted immunity for testifying against them, and the case was closed. Then a bomb exploded in the family home of the state's witness, instantly killing his father. Investigators turned to forensic science, hoping to determine if this was an act of revenge and if there was a way to link the two deadly crimes.

E26. Cop Out

Dec 14, 2005 · 23m

Jan 11, 2006 · 23m
