Claire Davis, a 17-year-old senior, was identified by Arapahoe County Sheriff Grayson Robinson as the girl who was critically wounded Friday, December 13, in a shooting at Arapahoe High School. A student who carried a shotgun into the school in Centennial, Colorado, and asked where to find a specific teacher.

The student then opened fire before apparently killing himself, Robinson said. In less than 80 seconds, Karl Pierson "fired one random shot down a hallway," then entered an area where 17-year-old Claire Esther Davis was seated with a friend, "and shot the female victim point-blank" in the head. "There was no time for the victim to run from the shooter," Robinson told reporters on Saturday.

That ignited at least three bookshelves, causing smoke to pour into the library.

He then fired a fifth round and ran to the library’s back corner, "and there took his own life." " His intent was evil, and his evil intent was to harm multiple individuals, " Robinson said about Pierson, whose entrance into the school was documented on security cameras, as was the bulk of the one minute, 20 seconds of violence that ensued.

He added that, to his knowledge, the shooter and the victim did not know each other.
