Student Killed in Colorado STEM School Shooting Tuesday, Others Remain Injured

A student has died from the STEM school shooting in Colorado on Tuesday afternoon, the Douglas County Sheriff's Office stated. Seven others remain injured, and two suspects—one adult male and one juvenile male—have been taken into custody for the mass shooting at the school in Highlands Ranch.

"It is with extreme sadness that we can confirm that 1 student at the STEM School was killed in today's #stemshooting incident," the sheriff's department tweeted. "The immediate family has been notified. Douglas County Coroner Jill Romann has not officially identified the student is stating it's an 18 year old male."

The Douglas County Sheriff's Office responded to shots fired around 1:50 p.m. MT on Tuesday. The department initially called the scene "active and unstable."

Douglas County Sheriff Tony Spurlock said his officers arrived within two minutes of the call, as their office is located near the school. He said the rapid response most likely prevented further carnage within the charter school.

"I have to believe that the quick response of the officers that got inside that school helped save lives," Spurlock said in this Associated Press report.

"This is a terrible event, this is something that no one wants to happen in their community," Spurlock said. "But we are going to investigate and get to the bottom of this."

Holly Nicolson-Kluth, who's the Douglas County Undersheriff, said an administrator first reported the shooting that began in the middle school portion of the K-12 academy.

"As officers were arriving at the school, they could still hear gunshots,"Nicolson-Kluth said.

As of 5:08 p.m. MT, three of the eight injured students had been released from the hospital. Two students remained in critical condition and the condition of the other three were unknown at the time.

The names and genders of the injured students, who Sheriff Tony Spurlock said were all ages 15 and older, were not released. The sheriff called the event "terrible," and that his department would work to reach conclusions to why this happened.

Colorado Gov. Jared Polis said he would make the state's public-safety resources available to help secure the school and protect the students..

"The heart of all Colorado is with the victims and their families," Polis said in a statement.

Here is a timeline of events as they happened today.

Highlands Ranch is located approximately 8 miles from Columbine, which just saw the 20th anniversary of its deadly school shooting pass just two weeks ago.

FBI and ATF agents reportedly arrived to assist the investigation.
