Kendrick Castillo was the 18-year-old sole victim of the May 7 Colorado school shooting. He died while trying to tackle one of the shooters.
The attackers were identified by law enforcement officials as 18-year-old Devon Erickson and 16-year-old Maya McKinney, also known as Alec. The two allegedly walked into the STEM School Highlands Ranch, a charter school outside of Denver, through an entrance without metal detectors and opened fire in two classrooms.
