During the school shooting, Calderon was locked in a closet with fellow students for three to four hours.I was in a closet, locked for four hours with people who I would consider almost family, crying and weeping on me, begging for their lives. I understand what it’s like to text my parents, ‘Goodbye, I might never ever, ever get to see you again. I love you.’ I understand what it’s like to fear for your life.At the time of the shooting, Calderon was 16 years old and junior at the high school.
Activism
Four days after the shooting, Calderon and others had co-founded an activist movement they named "Never Again", which advocates for stricter background checks prior to gun purchases.
Calderon was one of the surviving students interviewed by Lulu Garcia-Navarro of NPR that same night.
