Dave Cullen: Columbine

The custodian was running late on Tuesday. He hit the stop button at 11:14, and no bombs were visible; neither was Eric or Dylan. While waiting out the rewind, the custodian got a phone call. He talked, and the tape sat a little longer. He got the new tape in and hit Record at 11:22, leaving an eight-minute gap. The first frame shows the bombs visible and students near the windows beginning to react. Something peculiar outside has caught their attention.

Columbine ran on a bell schedule, and most of its inhabitants followed a strict routine. Several of them had broken it Tuesday morning. Patrick Ireland, the junior afraid to ask Laura to the prom, liked variety. Some days he spent “A” lunch in the library, others in the cafeteria. He had stayed up late talking to Laura on the phone again, and still had to finish his stats homework. So he headed to the library with four of his buddies as Eric and Dylan positioned the duffel bags. Patrick sat down at a table just above one of the bombs.

Cassie Bernall, the Evangelical junior who had transferred to Columbine to enlighten nonbelievers, pulled up a chair near the window. It was unusual to find her in the library at this hour. She was also behind on her homework, trying to complete an English assignment on Macbeth . But she was happy she had finished the presentation she would be making to her youth group that night.

Mr. D was oddly absent from the cafeteria. His secretary had booked an interview, delaying his rounds. He sat in his office at the opposite end of the main corridor, waiting for a young teacher to arrive. Mr. D. was about to offer him a permanent position.

Deputy Neil Gardner, the community resource officer, worked for the sheriff’s department but was assigned full-time to Columbine. He normally ate with the kids, and “A” lunch was his optimal chance for bonding, a key element of his job. He wore the same security uniform with the bright yellow shirt every day, so he was easy to spot. Tuesday, Gardner took a break from his normal routine. He didn’t care for the teriyaki on the menu, so he went for takeout from Subway with his campus boss— an unarmed civilian security guard. It was a beautiful day, lots of kids were outside, so they decided to check out the smokers. They ate their sandwiches in Gardner’s squad car, in the faculty lot beside the smokers’ pit on the opposite side of the school.

Robyn Anderson sat in her car nearby. She had driven out of the senior lot just about the time Eric and Dylan were hauling the bombs in, but had missed them. She’d swung around the building to pick up two friends. She got antsy—lunchtime was slipping away. Five minutes passed, maybe ten. Finally, the girls appeared. Robyn snarled at them, and they drove off. On the opposite end of the school, shots had already been fired.

A freshman named Danny Rohrbough went to the commons to meet up with two buddies. After a few minutes, they decided to head out for a smoke. If the bombs had worked, that choice might have saved him. He might have gotten out just in time. They headed out a side exit at the worst moment, directly alongside the senior parking lot.

The bombers spent a minute or two by their cars. They knew the diversionary bomb should have already blown three miles to the south. In fact, it had fizzled. A surveyor working in the area had moved it, and then the pipe bombs and one of the spray cans had detonated, producing a loud bang and a grass fire. But the propane tanks—the main explosive force—lay undisturbed in the burning field. The decoy was Eric’s only big bomb to ignite at all, but one of his dumber ideas. Officials learned of it just as the shooting started, four minutes before the first call from the school. The chief effect was to alert authorities that something was amiss in the area. Nothing of consequence was diverted.

Eric and Dylan had to proceed on faith.

As far as Eric and Dylan knew, cops were already speeding south. They would see the commons disintegrate, though. Each car was positioned for a perfect view. The cafeteria would explode in front of them; they would watch their classmates be torn apart and incinerated, and their high school burning to the ground.

At 11:18, the school stood intact. Some kids had already made it through the lunch lines and were strolling outside, settling onto the lawn for a little picnic. No sign of disturbance. The timing devices were not precise. No digital readouts with seconds counting down in red numerals; they were old-fashioned clocks with a third little alarm hand positioned two-fifths of the way between the 3 and the 4. But they should have blown by now.

Hundreds of targets streamed out the student entrance. They hopped into their cars and zipped away. Time for Plan B. There was no Plan B. Eric had staggering confidence in himself. He left no indication that he planned for contingencies. Dylan left no indication that he planned much of anything.

They could just proceed to Act II: mow the departers down in a cross fire and advance on the exits as scripted. They still could have topped McVeigh. But they didn’t. The bomb failure appears to have rattled one of the boys.

No one observed what happened next. Either boy might have panicked, but Eric was unflappable, the reverse of his partner. The physical evidence also points to Dylan. Eric apparently acted swiftly to retrieve his emotional young partner.

We don’t know whether they employed their hand signals, or how they came together. We know that Eric was in the prime location yet abandoned it to come to Dylan’s. And Eric moved quickly. Within two minutes, Eric had figured out that the bombs had failed, grabbed his packs, crossed the lot to Dylan’s car, rushed with him to the building, and climbed the external stairs to the west exit. That’s the first place they were observed, at 11:19.

Their new position set them on the highest point on campus, where they could survey both lots and all the exits on that side of the building. But it took them away from their primary target: the student entrance, still disgorging students. They could no longer triangulate or advance aggressively without separating.

At 11:19 they opened the duffel bags at the top of the stairs, pulled out the shotguns, and strapped them to their bodies. They locked and loaded the semiautomatics. One of them yelled, “Go! Go!” Somebody, almost certainly Eric, opened fire.

Eric wheeled around and shot at anyone he could see. Dylan cheered him on. He rarely fired. They hit pedestrians among the trees, picnickers to the south, kids coming up the stairs to the east. They tossed pipe bombs down the stairs, into the grass, and onto the roof. And they shared a whole lot of hoots and howls and hearty laughs. What a freaking wild time.

Rachel Scott and her friend Richard Castaldo were the first down. They had been eating their lunch in the grass. Eric shot Richard in the arms and torso. He hit Rachel in the chest and head. Rachel died instantly. Richard played dead. Eric fell for it.

Danny and his smoking buddies Lance Kirklin and Sean Graves were headed up the dirt path toward the stairs. They saw the gunmen firing, but assumed it was a paintball game or a senior prank. It looked like fun. They rushed straight toward the shooters, to get closer to the action. Danny got out ahead, making it halfway up the stairs. Eric pivoted and fired his carbine rifle. A shot tore through Danny’s left knee: in the front and out the back. He stumbled and began to fall. Eric fired again and again. As Danny collapsed, he took a second bullet to the chest, and a third to the abdomen. The upper round went straight through him as well, causing severe trauma to his heart. It stopped pumping immediately. The third shot lacerated his liver and stomach, causing major organ damage and lodging inside.
