After the shooting , Newman was interviewed by the police and remained determined that he did not want his parents to be present during questioning , however Newman 's father had arrived sometime after to ask for the questioning to stop until a lawyer would be consulted . During questioning Newman stated that he wanted to use the attack as a way to end abuse from his father , brother , and others . He said he was tired of being called " stupid " by them . He researched the Columbine High School massacre on the Internet and planned the attack about a week in advance . He conclusively decided against using a knife because " he did not want to be up close when blood came out of any of the victims " . The night before the attack , Newman 's father had given him a collection of ammunition which included three live .38 caliber rounds . When his parents left the house to eat , he took his mother 's handgun from a small safe in his father 's closet and hid it in his backpack
