Colorado High School Shooter Identified
Karl Pierson is identified as the shooter at Arapahoe High School, who shot a student inside the school while seeking “revenge” on a staffer there.
Pierson, 18, went into the school armed with a shotgun looking for the school’s librarian, Tracy Murphy — who was head of the school’s speech and debate team and who had recently kicked Pierson off the team, sources told the CALL7 Investigators.
“We were just in the library doing some work and we heard a loud bang. I thought it might have been someone dropping something, but then I heard two more,” said senior Max Minne. “I knew it was a gun for sure.”
Minne, who was studying in the library during his 5th period class, said he started to approach the front door of the library to see what was happening.
“The shooter just ripped through the door, started yelling ‘Where’s Murphy?’ — That’s the main librarian of the school. I saw him bust through the door of the library with a gun, so I just took off and started yelling, ‘Everyone get out! Everyone get out!'”
