Davis had been in critical condition after being shot at point-blank range at Arapahoe High School in suburban Denver on Dec. 13.

Arapahoe County Sheriff Grayson Robinson says Davis appeared to be a random target.

Friends and well-wishers had been posting prayers online and raising money to help pay for her medical care.

Authorities say 18-year-old Karl Pierson, who entered the school armed with a shotgun, a machete and three Molotov cocktails, was likely targeting a librarian who had disciplined him. Robinson says Pierson shot Davis before killing himself. The librarian escaped the school unharmed.
