ABC News’ Diane Sawyer has landed the first television interview with Sue Klebold, mother of Columbine killer Dylan Klebold. While announced this morning, the primetime interview will not air until February ’16, coinciding with the publication of Klebold’s book, A Mother’s Reckoning: Living In The Aftermath Of Tragedy.

The interview will air during a one-hour ABC News special about school shootings, the lasting impact on the community, ideas for prevention, and mental health.

Klebold writes about the murders of 13 people in the school, committed by her son and Eric Harris at Columbine High School in a suburb of Denver, on April 20, 1999. Another 24 were injured; the two gunmen took their own lives in the school, ending the massacre. Klebold has said she is donating all of her profits from the book to research and to charitable foundations with a focus on mental health issues.

Excerpts from Sawyer’s in-depth interview will air across all ABC News platforms, including Good Morning America, World News Tonight With David Muir, Nightline, ABCNews.com, ABC News Radio and ABC NewsOne.
