20 Children Died in Newtown, Conn., School Massacre

(ABC) Twenty children died today when a heavily armed man invaded a Newtown, Conn., elementary school and sprayed staff and students with bullets.

The gunman, identified as Adam Lanza, 20, was found dead in the school.

Lt. Paul Vance said 18 children died in the school and two more died later in a hospital. Six adults were also slain, bringing the total to 26.

In addition to the casualties at the school, Lanza's mother Nancy Lanza was killed in her home, federal and state sources told ABC News.

According to sources, Lanza shot his mother in the face, then left his house armed with at least two semi automatic handguns, a Glock and a Sig Sauer, and a semi automatic rifle. He was also wearing a bullet proof vest.

Lanza drove to Sandy Hook Elementary School and continued his rampage, killing 26 people, authorities said. He was found dead at the school. It appears that he died from what is believed to be a self inflicted gunshot wound. The rifle was found in his car.
