The dead at the school include 18 children, ranging from kindergarden through to Grade 4. Two other children died later in hospital.
The gunman opened fire Friday morning (December 14th,2012) inside a school where his mother worked.
He blasted his way through the building as young students cowered helplessly in classrooms while their teachers and classmates were shot.
The gunman killed himself. Gov. Dannel P. Malloy says someone who lived with him also died.
Photos were taken of young students crying, others looking frightened, while being escorted by adults through a parking lot in a line, the childrens' hands on each others shoulders.
The shooting happened in Newtown, 60 miles northeast of New York City.
The suspect is 24-year-old Ryan Lanza. Police say his younger brother is being held for questioning as a possible second shooter. A law enforcement official says the boys' mother, Nancy Lanza, is presumed dead and worked at the school as a teacher.
The official added that Ryan Lanza's girlfriend and another friend are missing in New Jersey.
According to the official, the suspect drove to the school in his mother's car. Police say three guns were found at the scene. A rifle was recovered from the back of a car at the school, and two pistols were recovered inside the school.
