CENTENNIAL, CO – Investigators say that within 80 seconds, 18-year-old Karl Pierson entered Arapahoe High School in Centennial, Colorado, shot a fellow classmate and killed himself last Friday.
Claire Davis remains in critical condition, reportedly in a coma with brain trauma.
“Everyone that saw him realized that he was armed with a shotgun. The individual also had multiple rounds of shotgun ammunition strapped across his body, and he was also armed with a machete,” said Arapahoe County Sheriff Grayson Robinson.
It’s believed that Pierson’s target was his debate coach Tracy Murphy, who had suspended him from the team in September. The brevity of the attack is in-part attributed to the school’s active shooter protocol, and the fast action of an on-campus deputy, who was closing in on Pierson when he took his own life.
Davis’ family is asking people to pray for her recovery.
