Spectators view the outside of the boarded-up cafeteria. The partially-detonated propane bomb in a duffel bag left behind by the shooters blackened the floor and set off the overhead sprinklers. If it had fully detonated, it most likely would've dropped the library down on the cafeteria. It finally half-blew when Dylan threw something at it (caught on cafe surveillance but -what- was thrown couldn't be made out), taking out the front windows. Eric Harris and Dylan Klebold tried several times to get it to blow, including shooting at it. (See next picture.)Ĭhairs melted by the partial detonation of the propane bomb left in the cafeteria. In the background you can see the blue duffle bag that contained the other bomb, the one that partially detonated and took out the front windows. One of the propane bombs found in the wrecked cafeteria, pulled out of the kitchen by officials. The tented yellow cards on the tables are police evidence markers. Dan Rohrbough's body can be seen at the base of the stairs on the sidewalk. The white things heaped on the ground are window blinds. At the bottom of the photo on the far right is the broken window of the teacher's lounge where SWAT released students and teachers from the school. At the top of the photo you can see broken glass from the shot-up doors.
