The Arapahoe High School student shot by a classmate December 13th died on Saturday.
Seventeen-year-old senior Claire Davis had been in critical condition after being wounded at point-blank range by 18-year-old Karl Pierson while sitting with a friend in the school library. Authorities believe she was shot at random.
Authorities say Pierson was likely targeting a librarian/coach who dismissed him off the speech and debate team when he entered the suburban Denver high school with a shotgun, a machete and three Molotov cocktails. Arapahoe County Sheriff Grayson Robinson said Pierson shot Davis before killing himself.
He bought the gun legally at a local store on December 6th. Anyone over the age of 18 is allowed to buy a shotgun in Colorado. Only those over 21 can legally buy a handgun.
Steve Miles is an English teacher who taught Pierson as a freshman and said the librarian who ran the speech team dismissed Pierson, but he didn't know why.
Fellow students described Pierson as outspoken and smart, not a loner. They also said he held communist views.
