Authorities say at least 26 people, including 18 children, were killed Friday when a gunman clad in black military gear opened fire inside a Connecticut elementary school.
The shooter, identified as 24-year-old Ryan Lanza, lived in Hoboken, N.J., and had ties to Sandy Hook Elementary School in Newtown, Conn., according to officials. The gunman was found dead inside the building, but it remains unclear who killed him.
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 shooter was armed with a .223-caliber rifle. The motive is not yet known.
Police are also questioning another man in connection with the shooting. Witnesses told the Connecticut Post that a handcuffed man, dressed in camouflage, was led out of a nearby woods by officers.
