Multiple bombs. An arsenal of guns. Months of detailed planning for killing his family and then unleashing explosives and bullets on his classmates at Waseca's junior and senior high school.
It was all meant to happen on April 20, the 15th anniversary of the rampage at Columbine High School, John David LaDue told police.
By chance, LaDue was arrested last week as he was making final preparations for the attack that he was forced to postpone in April when the 20th fell on Easter Sunday. But the shocking details of the arsenal that the 17-year-old high school junior had amassed — undetected and unsuspected — masked another disturbing fact: His fascination with Columbine was hardly unique.
Instead, the portrait of LaDue spelled out in criminal charges is that of just the latest angry, disturbed teen who fell prey to the "Columbine effect," deciding to vent his frustrations and alienation in a murderous replay of the nation's most infamous school massacre.
Twelve students and one teacher died that day in April 1999, along with the two teenage gunmen, who killed themselves. A decade and a half later, the images still resonate: the grieving parents, the scrambling police officers, the videos of the shooters taking target practice. For adolescents who may also be battling the first signs of mental illness, Columbine strikes a chord, according to a number of experts on school violence and student psychology.
"Shooters get their inspiration from different places, depending on their own grievances and their own background," said Bruce Shapiro, executive director of the Dart Center for Journalism and Trauma at Columbia University. "But there's no doubt that many of these shooters learn from past events."
Steve Brock, president-elect of National Association of School Psychologists and a member of a national emergency response team who has visited the sites of school violence, including the 2005 shootings in Red Lake, Minn., said LaDue's plans for Waseca look a lot like Columbine because he had a similar motivation: He wanted the same, shocked attention.
"Young people see these acts and the incredible amount of attention given to it and believe, somehow, they'll derive some benefit," said Brock, a professor and school psychology program director at California State University, Sacramento.
