On Friday December 13, 2013 a day before the one year anniversary of the Newtown, Connecticut school shooting, another occurred at Arapahoe High School in Centennial, Colorado.

The shooter identified as Karl Pierson, age 18, entered the school with a shotgun demanding to see his debate teacher, Tracey Murphy, to confront her. After the teacher was notified that Pierson was looking for her, she immediately left the school. Witnesses state that Pierson became agitated and fired shots.

Pierson shot Claire Davis, age 17, a student at Arapahoe, in the head. It is now confirmed that after he shot Davis, he turned the gun on himself which resulted in his immediate death. Davis was brought to, Littleton Adventist Hospital, where she underwent surgery and is in critical condition, in a coma. “She is an innocent young lady, and she was an innocent victim of an evil act of violence,” said Country Sheriff Grayson Robinson.

After the shooting, students of the school were evacuated to the track.

Arapahoe sophomore, Nicholas Harguth-Galyas,  shared his experience with reporter Jamie Galyas. “Later they came back and got us out [after being under lock down]. We were all patted down and then walked across the cafeteria and outside. We had to hold out hands over our head and walked across to the track and was patted down again. We were questioned multiple times if we saw anything. There were hundreds of Swat, FBI, and police officers that all had machine guns such as AK-47 and Commandos. Some even had dogs. We then hugged all our friends and I was reunited with my teacher and was the first class to go on a bus to Euclid Middle School where I would be picked up by my mom.”

After an investigation, it was confirmed that two Molotov Cocktails were found in the school. Harguth-Galyas stated that the bombs did go off in the school. Pierson is said to have acted alone and there is now investigators searching Pierson’s home, car, and another home he had access to.
