LITTLETON, Colo. (December 21, 2013) Claire Davis, 17, died at a Colorado Hospital after more than a week in critical condition.
Davis was shot on December 13th by a classmate at Arapahoe High School.
Police say 18-year-old Karl Pierson shot Davis at random before killing himself.
They say Pierson was likely targeting a librarian who had disciplined him.
He entered the school with a shotgun, a machete, and three Molotov cocktails.
The librarian escaped the school unharmed.
The school is about eight miles east of Columbine High School in Littleton, where two teenagers killed 12 classmates and a teacher before killing themselves in 1999.
