A shooting at a Connecticut elementary school Friday left 27 people dead, including 18 children, an official said.

The official spoke on condition of anonymity because the investigation was still under way. Another official, speaking on condition of anonymity for the same reason, said the gunman at Sandy Hook Elementary in Newtown was killed and apparently had two guns.

Stephen Delgiadice said his 8-year-old daughter heard two big bangs and teachers told her to get in a corner. His daughter was fine.
