Given the similarities between the shooters at Columbine and Martin Peyerl and the short amount of time between their respective rampages , it is possible Peyerl was influenced by the massacre at Columbine High School on April 20 , 1999 . Martin commented one day leading up to November 1 , 1999 that it was " completely crazy what these guys have done " and that he believed Harris ' and Klebold 's actions to be " something we should do "
