An 18-year-old man was killed on Tuesday after two students entered a school in Highlands Ranch, Colorado, and opened fire, authorities said.
The shooting took place at STEM School Highlands Ranch, a public charter school with 1,850 students, from kindergarten to 12th grade. Douglas County Sheriff Tony Spurlock said the suspects, whose names have not been released, entered the school and opened fire in two classrooms. Deputies arrived within minutes, and after a struggle, the suspects were arrested.
Spurlock said the suspects were not known to authorities before Tuesday. The victim's name has not been released. Eight other students were injured, with two in serious condition, The Associated Press reports. STEM School Highlands Ranch is seven miles away from Columbine High School in Littleton, where two students killed 13 people 20 years ago last month.
