Klebold joined Harris at the library entrance. The two walked out of the library at 11:36. Cautiously, fearing the shooters' return, 10 injured and 29 uninjured survivors began to evacuate the library through the north emergency exit door, which led to the sidewalk adjacent to the west entrance. Kacey Ruegsegger was evacuated from the library by Craig Scott. Had she not been evacuated at this point, Ruegsegger would likely have bled to death from her injuries. Patrick Ireland, unconscious, and Lisa Kreutz, unable to move, remained in the building. Patti Nielson crawled into the exterior break room, into which Klebold had earlier fired shots, and hid in a cupboard.
