Sue Klebold is the mother of Dylan Klebold, one of the two shooters at Columbine High School who, in 1999, killed twelve students and a teacher, and wounded more than 20 others before taking their own lives. In our conversation with we explore how current day mass tragedies continue to affect her. We also look at how tragedies like Columbine occur - and how someone's thinking can become suicidal and homicidal. Before publishing her book, A Mother’s Reckoning: Living in the Aftermath of Tragedy, Sue spent 15 years excavating every detail of her family life, and trying to understand the crucial intersection between mental health problems and violence. Instead of becoming paralyzed by her grief and remorse, she worked to advance mental health awareness. Sue is donating all author’s profits from her book to organizations that promote brain health and prevent suicide.
