ABC Samuel Granillo survived the 1999 shooting at Columbine as a 17-year-old junior. He was in the cafeteria when the shooting started and found himself hiding from the shooters in a nearby supply room with 17 other terrified students. The supply room's door had no lock and Sam soon heard the shooters' voices on the other side. Sam immediately understood that if he couldn't keep the door shut everyone in the room would probably die.
Now 32 years old, Sam is still struggling with the traumatizing memories of the violence he encountered that day. Even though they're ever-present, he is able to live a fairly normal life for eleven months of the year — but everything changes when the month of April comes around.
"It's spring. The weather is beautiful. Everything is blooming with life. And all I think about is death," Sam says.
And he's not the only one. Fifteen years after the massacre, the lives of many Columbine survivors come to a stand-still as the shooting anniversary nears.
