Columbine Hero

David Sanders was a teacher at Columbine High School during the Columbine shooting. The 1999 massacre was carried out by two unhinged seniors. Sanders was captured in a still image here, as he warns students in the cafeteria that there were gunmen on the loose. Immediately after this image was captured, he ran into the hallway where he was gunned down by the psychopaths.
