Consider this a new volume in the school shooting stories that keep mounting in this country. It has been reported that Adam Lanza went on a shooting rampage at Sandy Hook Elementary School in Newtown, Connecticut.

ABC News reports that over 20 people, primarily children, have been killed. The gunman is said to be among the reported deaths. At present, there is speculation that there may have been a second shooter, but those reports have not been confirmed. A random purple van in Danbury is also believed to be in connection with the shooting:

The first 911 call reportedly came in just after 9:40 a.m., stating that multiple students were trapped in a classroom with a gunman, who authorities say was an adult who had at least two guns. The school locks its exterior doors during the school day, so it is unclear how the gunman or gunmen gained access to the building.

Students were escorted from the building and evacuated to a nearby firehouse, and a reverse 911 call went out to parents. Some children could be seen reuniting with their parents outside the firehouse, but at least one group of students remain unaccounted for.

Some children of Sandy Hook Elementary School  are already being treated for trauma.

Sandy Hook Elementary School reportedly has over 600 students from kindergarten through fourth grade. One entire class of children has not been accounted for. The school is still being searched by authorities and some families are still missing children in this desperate hour:

Superintendent of schools Kathy June released the following statement: “Due to reports of a shooting as yet unconfirmed, the district is taking preventive measures by putting all schools in lockdown until we ensure the safety of all students and staff. All public and private schools in the town are in a lockdown situation.”

At present, this elementary school shooting is positioned to be the worst in American history.

UPDATE: Associated Press has confirmed 27 dead.
