Tragedy In Connecticut: 20 Children, 6 Adults Killed At Elementary School
The nation watched in horror Friday as the scope of a tragedy in Newtown, Conn., became clear. As a visibly upset President Obama said at midafternoon, "our hearts are broken."
At Newtown's Sandy Hook Elementary School, authorities say, a gunman identified by federal law enforcement officials as 20-year-old Adam Lanza fatally wounded 20 children — some as young as 5, according to the president — and six adults. One other person was injured. Lanza was found dead at the scene.
It ranks as the worst such attack at an elementary, middle or high school in the nation's history, horribly surpassing the 13 people killed by two students at Colorado's Columbine High School in 1999.
The incident began around 9:30 a.m. ET. Sandy Hook is a K-4 school. According to state records, there are about 670 students enrolled there.
We have been monitoring and updating as this story develops. Bear in mind: During breaking news events, there's often conflicting information coming from various news outlets. We will focus on what's coming from credible outlets and sources.

Earlier today, sources told NPR and other news outlets that the shooter was Ryan Lanza. They have since worked to clear up the confusion. Authorities are executing search warrants at the Lanza home in Newtown. The brothers' mother, according to multiple news reports was a teacher at the school.
Update at 7:15 p.m. ET. Teacher: 'You Could Hear The Shots, And There Were A Lot Of Gunshots":
KPCC's Air Talk spoke with Abbey Clements, a second grade teacher at the school, who describes how at first she thought the noises were chairs falling. As she realized they were gunshots, she helped students get to safety. "It just breaks my heart," she said of the children and friends who died. "And my heart breaks for those little students who had to listen to those gunshots," she said. "I couldn't stop the sound coming through."
Update at 7 p.m. ET. Audio From Police Radio Calls:

Update at 6:30 p.m. ET. "Evil Visited This Community."
Trying to describe what happened in his state today, Gov. Dan Malloy (D) said a short time ago that "evil visited this community." But, he vowed, "we'll get through this."
In Newtown, NPR's Joel Rose reports, people "seem numb ... they describe themselves as numb."
Update at 6:10 p.m. ET. Expressions Of Grief:

"There will be a mass in St. Rose of Lima Church at 7pm tonight (Friday), and the church will be open all evening for prayer."
"Most mass killers have suffered some kind of chronic depression and frustration," Northeastern University professor of sociology and criminology Jack Levin tells NPR. "Over a long period of time they externalize responsibility, blaming everybody but themselves for their failings."
At 2:45 p.m. ET, we posted that a law enforcement source in position to know told NPR's Carrie Johnson that the gunman's name was Ryan Lanza. Other news outlets have been reporting that the gunman might be Adam Lanza, said to be Ryan's brother. The law enforcement source now advises NPR that news outlets should wait for Connecticut authorities to resolve the confusion.
As you see, we're working to clear things up. In the interest of not repeating misinformation, we've removed the 2:45 p.m. ET update so that someone coming to this post won't be confused.
