Updated: The deceased suspect of this incident has been identified as Karl Halverson Pierson, 18, who had recently been removed from the debate team.
Two people were reported injured on Friday the 13th of December 2013, a year after the Friday the 14th of December 2012 school shooting in Newtown, Connecticut. Today's afternoon shooting at a suburban Denver high school left the suspect dead from a self-inflicted gunshot, according to the sheriff.
The shooting occurred at Arapahoe High School, in Centennial, Colorado. It is located 6 miles from Littleton, and is in the Littleton School District. The mascot of the high school is the Arapahoe Warrior.
Police, who surrounded the school, described the scene as a "active shooter situation" until the suspect student shooter was found dead.
Students were seen calmly exiting the building single file with their hands above their hands, gathering on a school track, at about 1:30 local time.
The Denver Post said there are reports of a fire at the school, home to about 2,200 students.
Considering this blog's attention to the name game, the copycat effect, and especially the name Aurora, this entry about Centennial from Wikipedia is intriguing:
Since the city is relatively new, many people in the Denver-Aurora metropolitan area do not recognize the area by the name “Centennial,” especially since neighboring Aurora, Englewood and Littleton are assigned by the United States Postal Service as the “default” place names for the ZIP codes serving Centennial. Thus, mailing addresses in which “Aurora,” “Englewood” or “Littleton” appear may actually be in Centennial. This causes considerable confusion, as Centennial and Englewood do not even share a common boundary, while some portions of Centennial are surrounded by Aurora and vice versa.
