Four Delaware (Lenape) American Indians entered the schoolhouse near present - day Greencastle, Pennsylvania, and shot and killed schoolmaster Enoch Brown and nine children (reports vary). Only two children survived . However, this incident may only incidentally be considered a school "shooting" because only the teacher was shot, while the other nine victims were killed with melee weapons . </Td> </Tr> </Table> <Tr> <Th> Date </Th> <Th> Location </Th> <Th> Deaths </Th> <Th> Injuries </Th> <Th> Description </Th> </Tr>
