STEM shooting: What is known so far

Nine students were shot shortly before 2 p.m. May 7 at STEM School Highlands Ranch. Here are key details known to Colorado Community Media:

• STEM senior Kendrick Castillo was killed. Castillo was shot while trying to save others from one of the armed suspects, classmates have said.
• Eight students were wounded. All students have been treated and released from area hospitals.
• Two suspects, both STEM students, were arrested. One is Devon Erickson, 18. He was booked on 29 counts of attempted first-degree murder and one count of first-degree murder, according to court records. The other suspect is a juvenile. The sheriff’s office is identifying the suspect as a female, but the suspect’s lawyer says his client uses male pronouns, such as “he.” That suspect will not be identified by Colorado Community Media unless charged as an adult by the 18th Judicial District Attorney’s Office. It was not immediately known what charges this suspect will face.
• Authorities say two handguns were found at the scene during the early stages of their investigation. No motive for the shooting has been given by authorities.
• Both suspects made their first court appearance on May 8. A second court appearance scheduled for May 10 was postponed until Wednesday, May 15, at the Douglas County Justice Center in Castle Rock.
• STEM School Highlands Ranch is a K-12 charter school of about 1,800 students at 8773 S. Ridgeline Blvd., west of Broadway and south of C-470. STEM does not have a school resource officer, but employs a private security firm. A security guard was at the school the day of the shooting, and the owner of the security company says the guard helped detain one of the suspects.
