Twenty-seven people, including 18 children, have been killed in a shooting at Sandy Hook Elementary School, according to the Associated Press.
The suspected shooter is 20-years-old, a law enforcement source with knowledge of the investigation tells CNN’s Susan Candiotti.
The death toll is closer to 30 than 20, a federal law enforcement source in Washington told CNN’s John King. Most of those killed are children, the source said.
A law enforcement official said the shooter, who is dead, was from New Jersey and had ties to Sandy Hook Elementary School in Newtown. Authorities recovered a Glock and Sig Sauer 9mm handgun, but it was unclear who killed the shooter, who wore black combat garb and a military vest.
Local news outlets report that the shooting occurred inside a kindergarten classroom, and that all the pupils in that classroom are unaccounted for.
An official with knowledge of the situation said the 20-year-old gunman, whose name has not been released, also had a .223-caliber rifle. The motive is not yet known.
