HIGHLANDS RANCH, Colo. — Last month, because the 20th anniversary of the Columbine High School taking pictures approached, STEM School Highlands Ranch joined lots of of colleges close to Denver in closing briefly amid safety issues. The anniversary got here and went, and faculties returned to their routines.
But on Tuesday afternoon, the STEM faculty’s worst fears have been realized when 9 of its college students have been shot, one fatally, and two fellow college students have been being held as suspects.
“We know two individuals walked into the STEM school, got deep inside the school and engaged students in two separate locations,” Sheriff Tony Spurlock of Douglas County stated at a information convention.
At 6:45 p.m., about 5 hours after the taking pictures, the Douglas County Sheriff’s Office launched an announcement confirming that one of many 9 who had been shot, an 18-year-old man, had died.
Late Tuesday evening, the sheriff’s workplace identified one of the suspects as Devon Erickson, 18, but said it would provide no further information about him because “we still have interviews to conduct and we want to make sure we have the most accurate information.”
Police tape was strung up outside the prim brick suburban home where neighbors said Mr. Erickson’s family has lived since the late 1990s. A next-door neighbor who declined to be named described him as a quiet young man who sometimes deflected eye contact and played several musical instruments.
Sheriff Spurlock said the suspects, who were armed with a handgun and other weapons, confronted law enforcement officers when they arrived. He said the suspects, Mr. Erickson and one juvenile, were not injured.
“I can tell you that there were shots fired,” he said. “Our officers went in and engaged the suspects. We did struggle with the suspects to take them into custody.”
Sheriff Spurlock said neither suspect had been on law enforcement’s radar before the shooting and that the motive was unknown.
The sheriff said the injured students were age 15 or older.
Students who were not injured were taken to Northridge Recreation Center in Highlands Ranch, where hundreds of anxious parents gathered to look for their children on Tuesday afternoon.
“I heard a gunshot,” said Makai Dixon, 8, a second grader who had been training for this moment, with active shooter drills and lockdowns, since he was in kindergarten. “I’d never heard it before.”
Makai’s parents said they joined thousands of others in rushing to the school as news blazed through this suburban community.
“We’re more messed up than they are,” Makai’s mother, Rocio, said as they walked to their car.
The shooting at the Highlands Ranch charter school is the latest at an educational institution, rattling communities nationwide because young people have been put in mortal danger in places long considered safe havens. One week earlier, a man with a pistol shot six people on the last day of spring classes at the University of North Carolina at Charlotte, killing two.
On Tuesday, as wave after wave of classes were released from the recreation center in Highlands Ranch, high schoolers began walking out in tears, reaching for their parents’ arms and hugging their teachers.
Tyler Rush, 17, a junior, said he had been on the second floor of the school, just above where the shooting occurred. He said that it began during the day’s final period and that the school announced a lockdown in the middle school portion of the building. He and his classmates gathered in a corner and turned out the lights. Some cried. Some sat paralyzed.
He heard two gunshots.
“I was in a state of shock,” he said.
Littleton Adventist Hospital in Colorado said five people were transported there after Tuesday’s shooting. Two are in serious condition while three have been discharged, the hospital said. Sky Ridge Medical Center said two children were transported there and were in stable condition. Children’s Hospital Colorado said one victim had been treated at its south campus and then released.
While details of how the shooting happened remained sparse, one parent said students had tried to stop the attack.
Brad Bialy said his oldest son, Brendan, a senior, told him that he was in class when gunfire erupted. Mr. Bialy said his son told him that two students entered the classroom and one pulled a gun out of a guitar case.
He said his son and two friends tried to tackle the gunman but one of the boys was shot in the chest. Other students tried to stanch the bleeding by putting pressure on his chest, Mr. Bialy said.
“Thank God he’s fine,” Mr. Montoya said.
He said after news of the shooting broke, he could not reach his son and was in a state of shock until they were able to talk to each other.
“We are so lucky,” Mr. Montoya said.
Sheriff Spurlock said the school, which has about 1,800 students in kindergarten through 12th grade, had no police officer assigned to it and used private security instead, but he did not say what actions that security service may have taken during the shooting.
The sheriff said that the school alerted law enforcement “almost immediately after the first gunshots were fired” and that deputies arrived roughly two minutes later.
“I have to believe that the quick response of officers that got inside that school helped save lives,” the sheriff said.
Earlier in the day, local news media showed video footage of tear-stricken parents gathering near the school as at least two air ambulance helicopters arrived at the scene after the shooting, which was reported before 2 p.m.
Gov. Jared Polis of Colorado said the state government was monitoring the situation.
“We are making all of our public safety resources available to assist the Douglas County Sheriff’s Department in their effort to secure the site and evacuate the students,” he said on Twitter. “The heart of all Colorado is with the victims & their families.”
STEM School will be closed for the rest of the week, the Douglas County schools superintendent, Thomas S. Tucker, said late Tuesday. Other schools in the district remain open, he added, with “heightened security.”
Douglas County is an affluent area south of Denver with about 350,000 people. It sits next to Jefferson County, home to Columbine High School, and students there are already primed to watch for gunmen.
Last month, hundreds of schools in the Denver area were closed as law enforcement searched for a Florida woman who they said had made threats ahead of the 20th anniversary of the deadly shooting that claimed 13 lives at Columbine High School, which is about seven miles from the site of Tuesday’s shooting.
The woman, Sol Pais, 18, was found dead on April 17 of an apparent self-inflicted shotgun wound in the mountains west of Denver.
Douglas County is more conservative than traditionally blue Denver, and like much of the region has been at the center of the national debate over gun violence.
Last month, Mr. Polis signed into law a so-called Red Flag bill, allowing authorities to take guns from people deemed a threat after a court hearing. The bill divided the state, and some sheriffs said they would not enforce it, while some counties began calling themselves “Second Amendment sanctuaries.”
In Douglas County, the county commission criticized the bill, saying they feared it threatened constitutional liberties, while Sheriff Spurlock emerged as one of its most vocal supporters.
The area’s history of gun violence was front and center in last year’s election for its United States representative. Jason Crow, a Democrat, unseated Mike Coffman, a five-term Republican incumbent supported by the National Rifle Association.
Mr. Crow campaigned openly on gun control — including universal background checks, a ban on assault weapons and restrictions on high-capacity magazines — and the issue dominated the race.
He was one of several public figures to express his sorrow on Twitter on Tuesday.
“It is with broken hearts that we respond to the news coming out of Highlands Ranch,” he wrote. “We still don’t have all the details regarding the situation at STEM school, but we do know this: we have a public health crisis on our hands. This cannot continue.”
Patrick Neville, a Columbine survivor and the top Republican lawmaker in the Colorado House of Representatives, said in a statement that the shooting was a reminder “of the need to secure our schools.”
He said armed security guards and facility upgrades were the best way to keep students safe.
“School safety programs which include armed security and safety upgrades to school facilities are the best way to stop these criminals from harming our children,” he said.
There have been several high-profile shootings in Colorado in recent years.
In 2010, a man shot two students with a high-powered rifle at a suburban middle school near Highlands Ranch.
In 2012, 12 people were killed at a movie theater in Aurora, Colo., about 20 miles northeast of Highlands Ranch.
In 2013, a student in Centennial, Colo., killed himself after he fatally shot another student in the head.
