Fashion Police

Sworded Scheme

In 2004, Mary Ann Clibbery was found brutally murdered in her Illinois business and investigators had to determine if this was a robbery gone wrong or a calculated murder. The evidence at the scene told police what happened and they got a huge break when evidence from the murder was found on top of a nearby frozen river.

Frozen Assets

In 2006, Texas real estate agent Sarah Anne Walker was found brutally murdered in a model home. Weeks later, a witness came forward who may have seen the killer and police used forensic hypnosis to help him recall every detail of the man's appearance. His description was used to create a composite sketch, which police used to draw the killer out of hiding.

House Hunting

In 2003, St. Cloud teenager Jason MacLennan returned home after a night out with friends and discovered his father Ken's body lying in a pool of blood. There were shoe impressions outside in the new-fallen snow; because the victim's wallet and watch were missing, the motive may have been robbery. But before making that determination, police needed to find out who had the most to gain from his death.

Shoot to Thrill

In 2006, Nevada politician Kathy Augustine died mysteriously during a hard-fought re-election campaign and the medical examiner could neither isolate the cause of death, nor explain the tiny puncture wounds discovered during the autopsy. Upon deeper analysis, investigators focus on her husband Chaz Higgs, a critical care nurse who had ready access to succinylcholine.

Political Thriller

In 1996, Virginia Beach police arrive at the Makdessi apartment to find Elise Makdessi and her lover Quincy Brown dead. Elise's husband Eddie had reported that he killed Quincy Brown in self defense after Brown had murdered Elise. Eddie gave the police a videotape Elise had made a week before, alleging that she had been the victim of sexual harassment and assault while in the Navy. Investigators found evidence that her allegations may have been part of an elaborate scheme for financial gain. Hoping to separate fact from fiction, they turned to forensic science.

Double Cross

In 1999, Patrick McRae was found dead in his Des Moines home and the crime scene was awash with blood. Analysis showed it had come from two people, one of whom was female. The male DNA was McRae's, which meant the killer was a woman. Leads dried up and the case went cold until a suspect arrested for drug possession offered police a deal, and told a bizarre tale of an exotic dancer named Andrea Morris who listened to the voices in her head.

Dancing with the Devil

In 2000, the body of exotic dancer Rachel Siani was found beneath a New Jersey bridge and investigators wondered if she had committed suicide.

Police look at customers at the gentlemen's club and co-workers who had vendettas against the victim.

Last Dance

In 2000, construction manager Darrell North was found dead in his work trailer in Ft. Worth, Texas. When investigators arrived, they found that he had been stabbed 46 times, described as overkill and indicating a personal relationship between the victim and the attacker. Police hoped that, during the struggle, the killer had left some of his own blood and his DNA behind. Their challenge was to find it. Forensic science points to an unlikely suspect.

Constructive Criticism

In 2000, Judy Southern arrived home from work and was shot by a gunman waiting within. Her husband Allen arrived shortly afterwards, called 911 to report his wife had been shot and drove her to the hospital. She died on arrival and the investigation focused on her husband Allen, but forensic analysis and a suicide note found at the scene pointed to the killer.

Home Evasion

In 1986, Gary Dale Larson was stabbed to death in his Edmond, OK, home and then the killer sexually assaulted Larson's girlfriend Janet Haynes. Hayne's story seemed farfetched: The perpetrator was wearing only underwear and gloves broke into the house, stabbed Larson to death, then raped and terrorized her for hours afterwards. But, the evidence at the scene supported her story, and investigators turned for help to the FBI and their criminal profilers.

Window Watcher

In 1991, Dorothy Donovan was murdered in her Dover, DE home and police are skeptical when her son Charles Holden stated that she was murdered by a hitchhiker he had picked up. Their suspicions were heightened when he refused to take a polygraph test and they turned to forensic science. Would the blood and fingerprint evidence at the crime scene support Charles' story or prove his guilt?

Stranger in the Night

In 2001, Ginger Hayes and her infant son Nicholas were abducted during a carjacking and the crime had been reported by a witness within minutes of occurrence. 45 minutes after the kidnapping, When Ginger and Nicholas were found 50 miles away, Ginger had been beaten to death, but Nicholas was still alive. Further analysis of Ginger's car and evidence at the scene where Ginger was found both led to her killer.

Kidnapping

In the early hours of a morning just before Christmas, a college co-ed was abducted from the parking lot of her apartment.

Seedy Intentions

Digital enhancement of security camera video shows that what appears to be a casual encounter is actually a forced abduction, leading to murder. The perpetrator's M.O. is remarkably similar to another murder which occurred five months earlier, 15 miles away. When investigators learn the crimes might not be isolated or random, they also realize a serial killer may be on the loose.

DNA Dragnet

The woman had been sexually assaulted, stabbed repeatedly, and left for dead. She survived, and gave police a detailed description of her attacker. When someone who fit that description practically turned himself in, police were sure they had their man... until the DNA evidence proved them wrong.

Smiley Face

The victim was a self-made man who never minced words. Perhaps he was murdered by a disgruntled client or employee. Perhaps the racy photos in his safe held the clue to solving the crime. Or perhaps with the help of the IRS, investigators could follow the money and find the killer.

Dirty Laundry

A family vacation turns into a nightmare when the wife is found face-down in the lake. There are no witnesses and little conclusive evidence to help police determine if they're dealing with a suicide, an accident, or something more sinister... until a forensic pathologist uses a groundbreaking technique to discover the truth.

Drowning Sorrows

Needle in a Haystack

The victim had been stabbed more than a hundred times, leaving her bedroom soaked with blood. Even though her body was positioned in a suggestive way, she hadn't been sexually attacked. Was this a sex crime, or was it a random act of violence?

Room with a View

Hair Line

A bullet-riddled car, a missing driver, and no witnesses. Was this an ambush or a random attack? Had the victim been abducted or was she dead? The answers lay in a unique clue so tiny it was measured in millionths of a meter.

All That Glitters Is Gold

Even though their daughter had run away before, she'd always come back. Her parents were sure this time would be no different, but they were wrong.

Office Visit

In 2007, Brian & Beverly Mauck were found dead in their Graham, WA home. The killer obviously spent a great deal of time at the scene, wiping away his fingerprints and obscuring shoe impressions he’d tracked through blood trails on the floor.

Palm Saturday

Terrified, the young girl hid in her bedroom while her mother, Crystal Perry, was attacked and stabbed to death in her home in Bridgton, ME, on May 12, 1994. Investigators had a wealth of evidence: shoe impressions, distinctive blood drops, and the killer’s DNA. What they didn’t have was a basis for comparison.

Shoe-In for Murder

On December 10, 2003, a gunman opened fire as a family of four entered their home, killing two and wounding the others.
