The incident drew national attention because it happened inside a school, involved student attackers, and resulted in the death of Kendrick Castillo, an 18-year-old student who was remembered for trying to protect others. Public interest later grew as court records, witness testimony, and trial coverage revealed more details about the planning, the classroom attack, and the legal process that followed. The case was not only about one defendant. It became a larger story about school safety, youth violence, community grief, and the courage shown by students during a terrifying moment.
What Happened at STEM School Highlands Ranch?
The STEM School Highlands Ranch shooting occurred on May 7, 2019, in Highlands Ranch, Colorado. According to public reports, one student, Kendrick Castillo, was killed, and eight other students were injured. Erickson and Alec McKinney were identified as the two student attackers. The incident took place inside the school and became one of Colorado’s most discussed school violence cases because of the loss of life, the number of injured students, and the actions of classmates who tried to stop the attack. Police responded quickly, and both suspects were taken into custody.
The Role of Kendrick Castillo in the Case
Kendrick Castillo became central to the public memory of the case because of his actions during the shooting. Reports described him as one of the students who moved toward the attacker instead of running away. His bravery was widely recognized by classmates, family members, and the wider community. Kendrick was close to graduation and was remembered for his love of robotics, off-roading, and helping others. His death is the most painful part of the case and should remain the focus whenever the story is discussed. The public attention around Devon Erickson must never overshadow the victim, the survivors, or the families affected by the attack.
Devon Erickson and Alec McKinney
Devon Erickson was not the only person charged in the case. Alec McKinney was also involved and later pleaded guilty to multiple charges. Court coverage reported that McKinney testified during Erickson’s trial and described planning connected to the attack. This testimony became a major part of the prosecution’s case. The two defendants followed different legal paths, but both were ultimately convicted and sentenced. Their involvement made the case especially disturbing because both were students connected to the school environment where the attack happened.
The Investigation After the Shooting
After the shooting, investigators examined what happened before, during, and after the attack. Reports described weapons recovered in connection with the case and details that later appeared in affidavits, hearings, and trial testimony. Investigators also looked into communication between the defendants, possible planning, and the sequence of events inside the classroom. Because school shooting cases involve victims, minors, families, and trauma, the investigation was closely followed by local and national media. The details that emerged became important during the trial, especially when prosecutors worked to show intent, preparation, and responsibility.
The Charges Against Devon Erickson
Devon Erickson faced a long list of charges related to the attack. Public records and news reports state that he was convicted on 46 counts, including first-degree murder, attempted first-degree murder, conspiracy to commit first-degree murder, and supplying a juvenile with a handgun.

The jury reached its verdict in June 2021 after a trial that examined witness statements, evidence, and testimony from those connected to the case.
The Trial and Guilty Verdict
Devon Erickson’s trial ended with a guilty verdict in June 2021. Reports said the jury convicted him on all counts after several weeks of testimony. The trial was emotionally difficult for the community because it required survivors and families to revisit the events of the shooting. During the legal process, prosecutors argued that Erickson was responsible for his role in the attack, while the defense presented its own explanation of his involvement. In the end, the jury found him guilty on dozens of charges, including first-degree murder.

Erickson’s sentencing marked a major legal conclusion, but it did not end the grief or long-term impact for those affected.

It is a real tragedy involving a murdered student, injured survivors, grieving families, and a community that had to rebuild after violence.

How the Case Was Covered by Media
Media coverage of the case focused on the attack, the victims, the defendants, the trial, and the sentencing. Local outlets followed the courtroom process closely because the case affected a Colorado community directly. National outlets also reported on the verdict because school shootings remain a major public concern in the United States. However, responsible coverage matters.
