Dylan Klebold's Mother Talked About His Son's Crime With Diane Sawyer; 'The Guilt I Felt Is Huge'

Almost two decades ago, the Columbine High School shooting rampage gripped the entire country in horror as two nihilistic teenagers stormed the school and killed 13 people before taking their own lives.

For 17 years, Sue Klebold has been living with guilt for what her son Dylan did. Even up to this day, she still couldn't believe how her beloved son could turn into horrible person capable of mass murder.

The embattled mother of one of the killers only spoke a few times regarding the shooting incident in the past and turned down previous invitations for TV interviews. This time, however, she broke silence in an interview with ABC's Diane Sawyer.

She never saw it coming. Every day since 1999, she is still hounded by guilt for the missed warning signs that could have stopped her son from committing mass murder with his friend Eric Harris.

"I had all those illusions that everything was OK because, and more than anything else, because my love for him was so strong. If I had recognized that Dylan was experiencing some real mental distress, he would not have been there," said Klebold during the interview as quoted by CNN.

While she felt deep remorse and guilt for all the victims who died that day, she also counted her son as one of the victims.

"He was a human being. I feel that Dylan was a victim of some kind of malfunction going on in his brain," she explained as mentioned in a report by The Guardian.

According to a report by USA Today, Klebold's interview came three days before the release of her book titled "A Mother's Reckoning: Living in the Aftermath of Tragedy"- the proceeds shall be donated to a charitable research foundation focusing on mental illness.
