Columbine shooter’s mother says she thinks of victims daily

Dylan Klebold, 17, and Eric Harris, 18, on April 20, 1999, carried out, at the time, the most deadly school shooting in the nation’s history.

In the interview – which aired on Friday night – Mrs Klebold described how she had struggled in the years after the shooting.

In advance of it, CNN talked with Terri Roberts whose own son Charles killed five in a mass shooting at an Amish schoolhouse in Lancaster County in 2006.

“You can’t change what happened in the past and if I looked forward and focused on the positive in my life that’s what’s really important and that’s what helps and makes me get up every day”, she said. She concluded, “I have forgiven you and only wish you the best”.

In her first interview since the massacre that shocked a horrified public, Sue Klebold tells Diane Sawyer, “There is never a day that goes by where I don’t think of the people that Dylan harmed”. Her book, A Mother’s Reckoning: Living In The Aftermath Of Tragedy, is available to pre-order now.

During the interview, Klebold told the longtime ABC anchor that she believed that she was a good mother up until the shootings, and had no idea her son was capable of such a heinous crime.

But in an incredible gesture of forgiveness, Hochhalter took to Facebook Thursday to post a letter to Sue Klebold, the mother of Dylan Klebold, one of the Columbine shooters.

In her lengthy essay for O Magazine in 2009, Mrs Klebold wrote: ‘In the weeks and months that followed the killings, I was almost insane with sorrow for the suffering my son had caused, and with grief for the child I had lost’. “But I didn’t know”.

“It’s one thing to write 23 letters to those who were injured and 13 letters to those who had lost family members but to personalize each one – that speaks a lot”, she said. Sue admits that it’s hard to reconcile with the knowledge of what her son did. “I would feel exactly the way they did”. Most of us do not see suicidal thinking as the health threat that it is. “That it was a completely different world that he was living in”.

“I don’t ever, for a moment, mean to imply that I’m not conscious of the fact that he was a killer, because I am”, she said. The book’s publisher has said that Klebold will donate the profits from her book to charities devoted to mental health issues.

Sue Klebold says she feels “huge” guilt and much “self-loathing” when she thinks of her 17-year-old son Dylan’s fatal actions at Columbine high school.
