They initially struggled to find anyone with motive, but a journey into the nearby desert unearthed the key to unlocking the shocking case. A junior at Pocatello High School, Cassie was popular, earned good grades, and was known for being reliable. Police searched the crime scene. There was no murder weapon or signs of forced entry or a robbery.
John Ganske told Dateline. After school, Anna picked up Cassie and Matt and drove them to the home where the teens stepped up to watch the dogs and cats for the weekend. Anna checked in with her daughter with a call at around p. It was the last time she spoke to Cassie. At around 10 p. The blackout unsettled the teens. Matt called his parents and told them about it. He reluctantly went home when his folks picked him up at around p. Cassie declined to go with him since she was responsible for the pets.
He became a person of interest but had a solid alibi that cleared him from suspicion. Matt also revealed a fact that would change the course of the case. He told detectives that on September 22, two fellow students from the teens' school, Brian Draper and Torey Adamcik, had also been at the house. When they were interviewed by police, Draper and Adamcik claimed they went to a movie after leaving. When neither teen could recall what the movie they said they'd went to was about, that sent up a flare.
A theater employee who went to school with the teens confirmed that they were not at the movie. Draper agreed to take a polygraph test the next day. But before the exam began, he became distraught and said he needed to speak with the detectives. Accompanied by his parents, Draper stated that he and Adamcik had covertly returned to the home where Cassie was pet-sitting. They turned off the power to frighten Cassie and wore masks to disguise themselves. Draper claimed that he was shocked when Adamcik started stabbing Cassie.
Draper eventually led detectives to an area near Blackrock Canyon in Idaho where he and Adamcik had buried evidence of their heinous crime. Amid the clothing, weapons and masks, there was a burned videotape. Experts were able to salvage the tape β and what was on it chilled seasoned detectives. The video showed that Draper and Adamcik were determined to make their own real-life version of the slasher movie Scream.
