A shooting Tuesday afternoon at a
school in
Colorado sent at least eight people to the hospital and two suspects are in custody, the sheriff's office said.
Authorities believe that the two suspects behind the incident at STEM School Highlands Ranch -- an adult male and a juvenile male -- are students of the school, Douglas County Sheriff Tony Spurlock said during a news conference.
The suspects "walked into the STEM school, got deep inside the school and engaged students in two separate locations," the official said. "There were a number of students that were shot and injured."
Of the eight students taken to nearby hospitals, several are listed in critical condition, according to Spurlock. "No staff or officers" were injured, the sheriff's office
tweeted.
