Eight students were injured Tuesday after a shooting at STEM School Highlands Ranch in Colorado, just miles away from Columbine High School.
Two suspected shooters, an adult male and a juvenile male and both students, are in custody, Douglas County Sheriff Tony Spurlock said late Tuesday. One allegedly had a handgun, but Spurlock would not specify the type of guns used in the attack.
Deputies responded to the scene within two minutes, just before 2 p.m. local time, and "engaged the suspects," Spurlock said. The shooters fired at two different locations at the school, he said.
Police do not believe there are any more suspects.
Four victims were taken to Littleton Adventist Hospital in serious condition and one in fair condition, according to Denver 7. One was transported in good condition to Children's Hospital Colorado and two in unknown condition to Sky Ridge Medical Center.
Spurlock said all victims were students, 15 years and older, but did not identify anyone.
STEM School Highlands Ranch is located about 7.5 miles southeast of Columbine High School, where 13 people were killed on April 20, 1999.
Colorado Gov. Jared Polis said in a statement he was making all public safety resources available to assist in securing the site and evacuating students.
"We are monitoring the situation in real time," he said. "The heart of all Colorado is with the victims & their families."
The FBI has taken over the crime scene, Spurlock said. A suspect's car was found in a parking lot and officials are working to get search warrants for the car and both suspects' houses.
STEM School Highlands Ranch runs from kindergarten to 12th grade and serves 1,800 students.
Kelley Paulson, the mother of two students at the school, told the news outlet she first heard about the shooting through a text message from a friend who was in the school.
"She said 'guns, shooting, oh my god, oh my god.' And she could hear them and that's how I first knew," she told KMGH. "The next thing I know, I heard my son, who is calling me because all of the kids who were in middle school ... all immediately ran out of the building."
