According to their journals and video tapes, it is believed by investigators that the pair intended to detonate their propane bombs in the cafeteria at the busiest lunch hour, killing hundreds of students. After this, they would shoot survivors. They would also be able to stab or toss bombs. Eventually, bombs set in their cars in the parking lot would also detonate, killing more students as well as possibly any police officers, paramedics, firemen, or reporters who had come to the school. However, this failed to occur since the bombs in the cafeteria and cars failed to detonate.
