A Colorado high school student with an apparent grudge against a teacher wounded a classmate with a shotgun before killing himself, chilling a state that's still trying to make sense of mass shootings at Columbine High School and an Aurora movie theater.
Quick-thinking students at Arapahoe High School on Friday alerted the targeted teacher, who quickly left the building. Police immediately locked down the scene on the eve of the Newtown massacre anniversary — a somber reminder of how commonplace school violence has become.
A student armed with a shotgun apparently killed himself after opening fire at a Colorado high school, wounding two fellow students, police said Friday.
Arapahoe County Sheriff Grayson Robinson said the armed student entered the school and said he was looking for a specific teacher, calling him by name through the hallways. Robinson said another student confronted the gunman and then was shot.
"The teacher began to understand that he was being looked at [and] exited the school," Robinson said.
