UPDATE | 1 dead in school shooting outside Denver

HIGHLANDS RANCH, Colo. (AP) — Authorities say an 18-year-old male student was killed in a shooting at a suburban Denver school.

The Douglas County sheriff’s office confirmed the death in a tweet Tuesday but didn’t identify the student killed in the shooting at STEM School Highlands Ranch.

The death appears to be separate from the eight people who were treated at hospitals.

Two students are listed in serious condition, two are listed as stable with injuries that are not life-threatening, one is in good condition and three have been released.

Authorities have taken two students into custody after the shooting in the affluent community of Highlands Ranch near where two students shot and killed 13 people at Columbine High School 20 years ago.

HIGHLANDS RANCH, Colo. (AP) — A shooting at a suburban Denver middle school injured eight people today, and two suspects were in custody, authorities said.

Several people are in critical condition.

Douglas County Undersheriff Holly Nicholson-Kluth says there is a possible eighth injury and doesn't believe there are any other shooters, but tactical teams were still searching room by room. She did not know if there were fatalities or other details about the victims or the extent of their injuries.

Lines of firetrucks, ambulances and law enforcement vehicles from multiple agencies were at the school and medical helicopters landed on a grassy field.

The shooting occurred at the middle school at STEM School Highlands Ranch, a public charter with more than 1,850 students in kindergarten through 12th grades.

The sheriff's office said deputies responded around 1:50 p.m. to the school in the Highlands Ranch community about 15 miles south of Denver.

Nicholson-Kluth said police and deputies got there almost immediately and heard shots as they arrived. The school is near a sheriff's department substation.

The sheriff's office directed parents to a nearby recreational center to pick up their children.
