President Barack Obama teared up Friday as he addressed the nation after a mass shooting in Newtown, Conn. left 27 people dead, including 18 children.

A shooting rampage in this small Connecticut town on Friday morning left 28 people dead, including 20 children killed inside their elementary school, authorities said.

The dead included the suspected gunman, whom law enforcement sources identified as Adam Lanza, 20. Police said that Lanza first apparently killed his mother, Nancy Lanza, at the home they shared in Newtown. Then he drove in her car to Sandy Hook Elementary, the school at which Nancy Lanza taught kindergarten.
In the car, authorities said, were three guns: a .223 caliber “Bushmaster” rifle and two pistols, a Sig Sauer and a Glock.

At the school, authorities said, Adam Lanza shot and killed six adults — including the school’s principal — and 20 children. They were shot in two different rooms of the school, police said.

Police were called to the school after 9:35 a.m., and officers searched the classrooms for a shooter. When they found the gunman, however, he was dead by his own hand. No officer fired a shot.

One other person was injured in the shooting, but survived.

Friday’s shooting became the second-deadliest in U.S. history, after the rampage that killed 32 students at the Virginia Tech campus in Blacksburg, Va. It happened in a country that had grown darkly accusto.
