The FBI's forensic examiner, who testified at Pillault's sentencing, performed an examination of Pillault's computer and found numerous documents pertaining to the creation of bombs and other explosive devices. Pillault's computer also had folders entitled “columbine” and “serialkiller,” which contained pictures relating to the Columbine shooting and other high-profile serial killers. The forensic examiner also found evidence that Pillault had searched on YouTube.com for “Super Columbine Massacre RPG,” a game that recreated the Columbine Massacre. In addition, Pillault had searched on YouTube and Google for instructions on how to make a sawed-off shotgun and information about Molotov cocktails.
Part 1
The first witness was Dr. Heather Ross, a forensic psychologist who was ordered by the district court to complete a psychiatric examination of Pillault and to report on mental illness, treatment options, and risk assessment. Dr. Ross testified that Pillault started using drugs and alcohol at the age of fourteen and that prior to his arrest he smoked marijuana and drank vodka every day. Dr. Ross discussed Pillault's mental history and explained that Pillault had previously attempted suicide and was hospitalized for aggression and depression. Dr. Ross concluded that “should Mr. Pillault continue to abuse substances his risk for future dangerousness ․ is moderate to high risk; but would be much lower if he was to be able to avoid using substances in the future.”
Part 2
The district court also heard testimony from two of Pillault's ex-girlfriends, whom we will refer to as GF1 and GF2. GF1, who started spending a significant amount of time with Pillault in the eleventh grade, testified about his aggressive tendencies and described him as a bully who frequently got into fights. She testified that Pillault was obsessed with Columbine and that he admired Dylan Klebold, one of the shooters involved in the Columbine massacre. According to GF1, Pillault planned to attack Oxford High School and drew specific plans in a notebook detailing how he would carry out the attack. GF1 claimed that Pillault warned her not to go to school on April 20, the anniversary of the Columbine shooting. GF1 also testified that on one occasion, Pillault asked her to take him to Home Depot, where he purchased a long copper pipe that he said he later used to make a pipe bomb.
GF2 testified that she had known Pillault since the fifth grade and that she was dating him during the months surrounding his arrest. GF2 agreed that Pillault was obsessed with Columbine and claimed that he frequently threatened to reenact Columbine at Oxford High School. She believed that Pillault's threats were serious and that he truly wanted to go through with the attack. According to GF2, Pillault had a few specific plans for how he would initiate his attack, one of which involved breaking through the glass walls of the school's cafeteria using pipe bombs and smoke bombs. GF2 claimed that Pillault planned to save up money to buy guns and that she and Pillault went to Wal–Mart to look at gun prices. GF2 testified that on one occasion, Pillault tried to make a bomb out of a glass Sprite bottle, which he filled with kerosene. GF2 testified that she had known Pillault since the fifth grade and that she was dating him during the months surrounding his arrest.
Part 3(Think this did the biggest damage)
Given that the guy had a history making these threats, mental/addiction issues which manifested themselves into aggression and depression bouts, and had done some research into making molotv cocktails and sawed-off shotgun made him a very possible risk which the courts acted strictly against.
