Heather Martin is interviewed in Aurora, Colo., on Thursday, April 11, 2024. Martin, a survivor of the 1999 shooting at Columbine High School in suburban Denver, hid with 60 other students in a barricaded office during the attack. It's been a quarter-century since two gunmen killed 12 fellow students and a teacher at the school, and the trauma of that day continues to shadow Martin and others who were there.
