Two students are in custody after opening fire on their classmates at a Denver-area charter school Tuesday, police say. Sheriff Tony Spurlock says the suspects—one adult and one juvenile—were taken into custody within around two minutes of reports of shots being fired at the STEM School Highlands Ranch, the Denver Post reports. Authorities say an 18-year-old man was killed and eight other students were injured. "We know that two individuals walked into the STEM School, got deep inside the school and engaged students in two separate locations," Spurlock says. "There were a number of students that were shot and injured." The adult in custody has been named as Devon Erickson, 18. Spurlock says the injured students are all age 15 or older, the AP reports.
Authorities, who say the suspects had at least one handgun, have not commented on a motive. The Post reports that a Honda sedan with the words "(expletive) society" on the door and a pentagram with the numbers "666" on the hood was towed from the Erickson family home Tuesday night. Spurlock says the school, which has more than 1,850 students in kindergarten through 12th grade, doesn't have a resource officer assigned to it, but uses private security. Brad Bialy tells the New York Times that his son Brendan and two friends tried to tackle a gunman who entered a classroom and pulled a gun out of a guitar case. He says one of the boys was shot in the chest during the attempt to stop the shooting. (The shooting comes just weeks after local schools marked the 20th anniversary of the Columbine massacre.)
