S4 E1 • Invisible Intruder

Police received a call from Darlie Routier one morning telling them of her two sons' murders. However, police were unsure about the validity of Darlie's story and began an intensive search of the crime seen. The police determined the killer by analyzing blood spatter, doing behavioral profiling and analyzing Darlie's 911 call. The evidence proved that Darlie killed her two oldest sons with a knife, inflicted wounds on herself, cleaned the evidence and created a story of a crazed intruder who had come in the house. Darlie's motive was to obtain the $5,000 each of her sons had in a bank account.

S4 E7 • Ties That Bind

Two young boys were found tied and murdered with similar wounds within three months of each other. The rope used to tie the boys was very unique: it was made of left-over garbage in South Korea and used by the air force. Another clue turned up when one of the boy's brother was hypnotised and remembered a uniformed man in a tan car. Shortly after, someone noticed a strange car and gave the licence plate number to police. This vital information led to the conviction of John Joubert, an air force-enlisted man who carried the same exact rope used to bind the two boys.

S4 E8 • Body of Evidence

Karla Brown was the youngest of three girls in the Brown family. After many failed relationships, Karla became engaged to Mark Fair. The couple began moving into their dream home in June 1978. On the morning of June 20, Mark left for work and Karla remained at home. When Mark and a friend returned home that evening, they found Karla dead. The condition of Karla's body told investigators that she was a victim of sexual assault; she had resisted, struggled, and was killed. The Police questioned Paul Main and John Prante, who lived across the street. They were considered low-level suspects. After a second autopsy, they were able to re-examine bite marks. A Computer enhancement gave a better view of the bite marks, and the science of forensic odontology identified John Prante. On July 15, 1983, five years after the murder, Prante was found guilty and sentenced to 75 years in prison.

S4 E9 • Accident or Murder?

Clayton Johnson, a Nova Scotia schoolteacher, left for work on the morning of February 20, 1989. At 7.40 AM, the school bus arrived to pick up the Johnson children. At 7.51 Mrs. Molloy arrived to drop off her child at the Johnson home. She found Janice Johnson lying at the bottom of the basement stairs in a pool of blood. Clayton Johnson later married a 22-year-old member of his Pentecostal congregation. When homicide investigator Brian Oldford heard this, he became suspicious and decided to reinvestigate. He learned that Clayton had taken out a $125,000 life insurance policy on his first wife, Janice, shortly before she died. Clayton Johnson was charged with the first-degree murder. By examining the photos and nature of the injuries, they were convinced that she had fallen backwards. The accidental fall scenario would also account for the complete lack of defensive wounds on Mrs. Johnson or Mr. Johnson. Testimony was presented to the Canadian high courts and a decision is pending.

S4 E10 • Core Evidence

At 16 months of age, Anne Grace Gimmenstad became very ill and was rushed to the hospital, and within two weeks died. Following extensive medical examinations, it was determined that Anna had been the victim of the deadly bacteria E-Coli. Anna'a mother recalled a trip to the grocery store when Anna pointed excitedly at her favorite drink, Odwalla apple juice. As early as 1993, tests on samples of Odwalla juices found high levels of general bacteria. Federal and state inspections reports confirm that the company used two loads of apples with relatively high defect levels on the day the juice was made. The genetic markings on the E-Coli in the victims matched the bacteria found in the product bottled that day. Odwalla pleaded guilty to violating Federal food safety laws and agreed to pay a $1.5 million fine for the outbreak of E-Coli in its juices.
