Sue Klebold, the mother of Columbine killer Dylan Klebold, told ABC News’ Diane Sawyer that when the Columbine tragedy happened, she couldn’t stop thinking about the victims and their families.

“I just remember sitting there and reading about them, all these kids and the teacher,” Klebold said in an exclusive interview that will air in a special edition of “20/20” Friday at 10 p.m. ET on ABC.

“And I keep thinking– constantly thought how I would feel if it were the other way around and one of their children had shot mine,” she continued. “I would feel exactly the way they did. I know I would. I know I would.”

On April 20, 1999, Dylan Klebold and Eric Harris opened fire at Columbine High School, killing 12 students and one teacher, and wounding 24 more people before taking their own lives. The tragedy not only shocked the community in Littleton, Colorado, but stunned the nation and forever changed how school administrations and law enforcement handle school shootings.

“There is never a day that goes by where I don’t think of the people that Dylan harmed,” she said.

“You used the word ‘harmed,’” Sawyer observed.
