This is a evolving story and will be updated as more information is released.

Update: The Douglas County Coroner identified the 18-year-old killed in the shooting as Kendrick Castillo. Castillo attempted to lunge at one of the shooters, letting other students escape. He was then shot. He was only days away from his high school graduation, and his friends, family and community have praised him as a hero.

The two shooters appeared separately before a judge on May 8. 18-year-old Devon Erickson and the other shooter, whose name has not been released due to being a juvenile, are expected to be charged with murder and other crimes. All case related documents remain sealed, and a filing of charges is set for May 10.

At roughly 2:00 p.m. on Tuesday, May 7, two gunman opened fire in a K-12 school 10 miles south of DU at STEM School Highlands Ranch. An 18-year-old student was killed and eight students were reported injured, with the youngest victim being 15. Two students are in critical condition. It is unclear if the reported eight injured students includes the student who was killed.  

Authorities were able to respond quickly to the situation, which helped save more lives. The two gunmen walked, “deep inside the school,” and shot at students in two different locations. One gunmen is said to be a juvenile who attends the school while the other is an adult. Eyewitness testimony recalls one of the shooters pulling a gun out of a guitar case before firing on students.

Other eyewitnesses, like an 8-year-old students who reacted in bewilderment to what, she said, was hearing a gunshot for the first time and in her school. Other testimonies describe the shock and terror of older, high-school-age students.
