Columbine shooting

AL DIAZ / MIAMI HERALD

Most students who committed deadly school attacks over the past decade were badly bullied, had a history of disciplinary trouble and their behavior concerned others but was never reported, according to a U.S. Secret Service study released Thursday.

In at least four cases, attackers wanted to emulate other school shootings, including those at Columbine High School in Colorado, Virginia Tech University and Sandy Hook Elementary School in Connecticut. The research was launched following the shooting at Marjory Stoneman Douglas High School.

In the decades since two gunman attacked Columbine High School, ushering in a new era in which mass shootings have become commonplace in America, the building has turned into a tourism magnet for those curious about the school's dark history. And fears have persisted that the site has provided inspiration for copycat killings.

Over the past few months, visitors hoping to glimpse the school have been coming in droves, hitting record levels, perhaps fueled by the shooting's 20th anniversary.

Is it time to demolish the school?

On April 20, 1999, as two students carried out the deadly shooting at Columbine High School, senior Heather Martin was barricaded in a choir office with 60 other students. It would be several hours before emergency responders found the room and were able to help the group get out.

"I only saw the aftermath," she said. "I didn't see anything as it was happening." But she was shocked to find out that the perpetrators were two of her peers, including one she had grown up with.

It took her 10 years to return to her alma mater.

Sol Pais, the 18-year-old Miami Beach High student who traveled to Colorado, bought a shotgun and threatened violence against schools, has died of an apparent self-inflicted gunshot wound, police said Wednesday.

The FBI had said Pais was “armed and dangerous” and believed to be somewhere in Colorado after making “credible” threats days before the 20th anniversary of the Columbine High massacre that ushered in the modern era of mass shootings at U.S. schools.

Guy Grace, a school-security official whose Colorado community was rocked by the 1999 murders at Columbine High School, shared school-hardening solutions Wednesday with a commission formed after this year’s mass shooting at Marjory Stoneman Douglas High School in Parkland.

At schools across the country today, students are getting up from their desks and walking out when the clock strikes 10 a.m. They're participating in the National School Walkout, part of the movement that has taken hold among students to call for action to end gun violence.

Today marks 19 years since the shooting at Columbine High School in Littleton, Colo., in which two high school students shot and killed thirteen people.

It’s been 19 years since the shooting at Columbine High School in Colorado, a little more than two months since the massacre at Marjory Stoneman Douglas and just a few hours since a student in Ocala was hit with a bullet in his ankle.
