Dylan Bennet Klebold was born on September 11, 1981, in Lakewood, Colorado, to Thomas and Sue Klebold. On the day after the shooting, Klebold's mother remembered that shortly after Klebold's birth, she described what felt like a shadow had been cast over her, warning her that this child would bring her great sorrow. "I think I still make of it what I did at that time. It was a passing feeling that went over very quickly, like a shadow." Sue said in an interview with "Colorado Public Radio". Klebold was soon diagnosed with pyloric stenosis, a condition in which the opening between the stomach and small intestines thickens, causing severe vomiting during the first few months of life. Sue later assured herself that the feeling she had that her son would bring her immense sorrow, was that her son would be physically ill.
