Sue Klebold is the mother of Dylan Klebold, one of the two shooters who committed the Columbine High School massacre, murdering 12 students and a teacher. She’s spent years excavating every detail of her family life, trying to understand what she could have done to prevent her son’s violence. In this difficult, jarring talk, Klebold explores the intersection between mental health and violence, advocating for parents and professionals to continue to examine the link between suicidal and homicidal thinking.
