DENVER (AP) -- The mother of one of Columbine High School massacre gunman Dylan Klebold says she prayed that her son would kill himself.
The Denver Post reports Saturday that Sue Klebold made her statement in a new book titled: "Far From the Tree: Parents, Children, and the Search for Identity."
In a chapter about crime, author Andrew Solomon examines how parents of criminals find themselves "morally diminished."
Sue Klebold told Solomon that, "I saw the end product of my life's work: I had created a monster."
Twelve students and a teacher died at the school on April 20, 1999, before Klebold and Eric Harris committed suicide.
Sue Klebold says she held out hope that her son had not killed anyone before a sheriff's report documented that he did.
