Great sadness and the ever looming question, WHY? still looms large across my life. Why did Klebold and Harris go into Columbine high school on April 20, 1999 and kill 13 people? Why did my nephew Greg Barnes, a junior this year at Columbine, then kill himself on May 4, 2000 less than two weeks after the one-year anniversary of the shooting?
