The name Klebold should ring a bell, but not a happy one.
Dylan Klebold and Eric Harris were the two Columbine High School students who shot and killed 13 people at the school in 1999; they wounded 24 others before killing themselves.
The crime itself is incomprehensible to most of us, perhaps more so for Sue Klebold, Dylan's mother. She wrote a book about her journey before and after Columbine, .
The book is now out in paperback, with all profits going to research and charities working on mental illness. Sue Klebold shares her story with us.
