Gunman, 18, wounds classmate in Colorado school
CENTENNIAL, Colo. – A teenager who may have had a grudge against a teacher opened fire Friday with a shotgun at a suburban Denver high school, wounding a fellow student before killing himself.
Quick-thinking students at Arapahoe High School alerted the targeted teacher, who quickly left the building. The scene unfolded on the eve of the Newtown massacre anniversary, a somber reminder of the ever-present potential for violence in the nation’s schools.
The wounded student, a 15-year-old girl, underwent surgery and was in critical condition. Authorities originally said a second student was wounded, but Arapahoe County Sheriff Grayson Robinson said Friday night that the other girl taken to a hospital was covered in blood from the first student and wasn’t injured.
Robinson identified the shooter as Karl Halverson Pierson, 18. The sheriff did not elaborate on any possible motive except to say Pierson had a “confrontation or disagreement” with the teacher. He didn’t know if the injured girl was intentionally shot.
Pierson made no attempt to hide his weapon after entering the school from a parking lot and asking for the teacher by name, Robinson said.
When the teacher learned that he was being targeted, he left “in an effort to try to encourage the shooter to also leave the school,” the sheriff said. “That was a very wise tactical decision.”
Jessica Girard said she was in math class when she heard three shots.
“Then there was a bunch of yelling, and then I think one of the people who had been shot was yelling in the hallway, ‘Make it stop,'” she said.
Two suspected Molotov cocktails were also found inside the school, the sheriff said. Robinson said one was lit and thrown, but no one was injured.
The school was swiftly locked down. Within 20 minutes of the first report of a gunman, officers found Pierson’s body inside the school, Robinson said.
