When the situation in the Colorado Highlands Ranch STEM school went critical, Kendrick Castillo skipped the “Run, Hide” and went directly to “Fight”. As reported in
multiple news outlets , Kendrick sacrificed his life by rushing the shooter allowing other students to escape. A friend who is in a
Marine Corps deferred entry program, Brendan Bialy, also rushed and restrained the shooter.
It has been reported that there were no metal detectors at the school. Also reported somewhere is that the school’s private security, a former Marine, also ran to the scene and restrained a shooter.
