One 18-year-old male student is dead and seven others are injured after two classmates, one adult male and one juvenile, opened fire at a school in Denver, Colorado.
Gunfire erupted at STEM School Highlands Ranch on Tuesday afternoon at 1.53pm local time.
Douglas County Sheriff Tony Spurlock said shots were fired in two separate locations in the high school section of the campus, which serves grades kindergarten through 12th.

Administrators reported the gunfire immediately and deputies arrived on the scene within two minutes.
Spurlock said officers engaged the suspects and there was a struggle to bring them down. Neither suspect was injured in the confrontation.
Spurlock declined to identify the suspected shooters but said they are both believed to be students at the school.

Douglas County Sheriff Tony Spurlock said the suspects, a juvenile and an adult, were believed to be students at the school. Spurlock said there were no other suspects in the case, but authorities were still investigating at the scene.
According to a criminal background check, his only prior run-ins with the law include citations for careless driving and driving an unsafe vehicle.
Late Tuesday evening, the Douglas County Sheriff’s Office identified the 18-year-old alleged shooter as Devon Erickson.
“We will not be releasing any photos at this time as it could jeopardize this critical on-going invest.,” the sheriff’s office tweeted. “We still have interviews to conduct and we want to make sure we have the most accurate information.”
Multiple sources close to the investigation told late Tuesday night that the second suspect, who is a minor, is a transgender male who was in the midst of transitioning from female to male

The Douglas County Sheriff’s Office confirmed on Twitter that one of the eight victims, an 18-year-old boy, had died about two hours after the shooting.
Local media outlets previously reported that five victims were taken to Littleton Adventist hospital, where four are in serious condition and one is in fair condition.
Another two patients, both juveniles, were reportedly transported to Sky Ridge hospital where they are both in stable condition.
An eighth victim is said to be in good condition at Children’s Colorado hospital.
Spurlock declined to identify any of the students by name but said they were all aged 15 or older.
He said the families of seven victims were in contact with authorities, who have yet to make contact with the eighth victim.

Elementary school children were seen walking out of the school with their hands in the air as authorities started evacuating the scene.

Frantic parents have told how their children sent them texts and called them to tell them that shots had been fired.
The more than 1,800 students who attend the STEM school are being connected with their parents at reunification centers.
There was no school resource officer at the scene when the suspects opened fire.
Witnesses say one victim was seen being carried out by a cop on their shoulder. Another was seen being taken out on a stretcher, according to a witness.

Hundreds of people took to Twitter after news of the shooting broke to express their horror that yet another American school had been targeted.
The so-called #stemshooting is the 43rd incident of gunfire reported on a school campus so far in 2019 and the 116th mass shooting overall this year.
The STEM campus is located just seven miles from Columbine High School, where 13 people were killed and more than 20 were injured on April 20, 1999 – just over 20 years ago.
One student at a nearby high school tweeted: ‘Being a student in Colorado is terrifying. Threats, secure permitters, lockdowns, missing school because of credible threats, and now another school shooting. I’m tired. What is the government doing to help us? My death is inevitable. Please talk about this.’

Another user tweeted: ’20 years later, 7 miles from Columbine, and 0 actions taken in Washington to protect kids from gun violence.’
The STEM school, which has about 1,800 students from kindergarten through high school, is located off South Ridgeline Road and Plaza Drive in Highlands Ranch.
The school did not have a School Resource Officer assigned to the building, but it did have private security, Spurlock said.
