CNN reports that the Colorado shooting at Arapahoe High School was over in 80 seconds.
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.
Pierson then fired another round down a hallway, then entered the library, where he fired again and ignited one of the Molotov cocktails, according to Robinson.
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."
By 12:35 p.m., it was all over.It was the presence of an armed person that ended the shooting:
The rampage might have resulted in many more casualties had it not been for the quick response of a deputy sheriff who was working as a school resource officer at the school, Robinson said.
Once he learned of the threat, he ran -- accompanied by an unarmed school security officer and two administrators -- from the cafeteria to the library, Robinson said. "It's a fairly long hallway, but the deputy sheriff got there very quickly."
The deputy was yelling for people to get down and identified himself as a county deputy sheriff, Robinson said. "We know for a fact that the shooter knew that the deputy was in the immediate area and, while the deputy was containing the shooter, the shooter took his own life."So much for the pro-criminal supporters cries that armed persons couldn't stop a shooting at a school. However, it is notable that the shooter took Joe Biden's advice to get a shotgun. Probably because he was a liberal.
