Centennial, Colorado (CNN) -- It started just before 12:33 p.m. on Friday, moments after the high school senior and debate club member parked his car in the student lot at Arapahoe High School in suburban Denver, then -- wearing a bandolier containing shotgun shells and carrying a pump-action shotgun, a machete and a backpack holding three Molotov cocktails -- walked through a door adjacent to the library.

"He took no effort to conceal the fact that he was armed," said Arapahoe County Sheriff Grayson Robinson.

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.
