CENTENNIAL, COLO.: A teenager who wounded a fellow student before killing himself at a suburban Denver high school entered the building with a shotgun, a machete, three Molotov cocktails and ammunition strapped to his body, likely intending to track down a librarian who had disciplined him, authorities said Saturday.
After firing a round down a hallway, Karl Pierson, 18, shot a fellow student who just happened to be sitting nearby with a friend as he headed toward the library. Claire Davis, 17, was shot in the head at point-blank range and remained hospitalized Saturday in critical condition.
Authorities originally said a second student was wounded, but on Friday night clarified that the other girl taken to a hospital was covered in blood from the first student and wasn’t injured.
Pierson set off one of the devices, but killed himself just one minute and 20 seconds after entering the building because he knew a sheriff’s deputy assigned to the school was closing in, Arapahoe County Sheriff Grayson Robinson said at a news conference.
Pierson’s original target was believed to be a librarian who coached the school’s speech and debate team. The librarian, whose name was not released, had disciplined the teen in September for reasons that haven’t been disclosed.
The librarian was able to escape the school unharmed, Robinson said.
The sheriff also said Davis appeared to be a random target. Based on Pierson’s arsenal, Robinson believes the teen intended to hurt many others at the school just 8 miles from Columbine High School.
“His evil intent was to harm multiple individuals,” Robinson said.
Pierson legally purchased his shotgun at a local store a week before the shooting and bought the ammunition the day of the shooting. Anyone 18 and older is allowed to buy a shotgun in Colorado; only those over 21 can legally buy a handgun.
According to Robinson, Pierson fired another round down the hallway after wounding Davis. Pierson then entered the library, fired one shot and detonated one Molotov cocktail, which caused three bookshelves to catch fire. After that, he fired a fifth round, ran to a corner and shot himself.
Robinson said investigators believe Pierson made some kind of threat in September, after the librarian disciplined him.
“We are looking into that, to the degree that it was understood, and then what interactions or interventions took place,” the sheriff said. No other details on the threat were released.
Students and a teacher described Pierson as a smart and sometimes goofy student who often talked about his beliefs during class, sometimes even debating his teachers. They said he was outspoken about his Communist-leaning political views. They also said he was an Eagle Scout who finished at the top of speech competitions.
Pierson competed in extemporaneous speaking — in which students prepare short speeches on current events — in the National Forensic League’s national tournament in June in Birmingham, Ala. He didn’t advance to the elimination rounds, the league said.
“I think he [Pierson] really cultivated his speech and argument skills and really thought that was a big part of his identity,” said Steve Miles, an English teacher who taught Pierson as a freshman.
Zach Runberg, 18, a fellow senior from Pierson’s English class, said the teen was funny and made intelligent jokes.
“He would speak for himself,” Runberg said. “He would not be afraid to tell someone how he feels.”
Pierson, whose parents were divorced, lived at least part of the time with his mother in a higher-end neighborhood in suburban Highlands Ranch. The front door was covered with plywood Saturday after authorities conducted a search overnight.
Meanwhile, the family of the wounded student issued a statement Saturday asking for privacy and saying she is suffering from severe head trauma.
