NEWTOWN, Conn. (AP) — A man opened fire Friday inside the Connecticut elementary school where his mother worked as a teacher, killing 26 people, including 20 children, by blasting his way through two rooms as youngsters cowered helplessly in the building.
The gunman killed himself and another person was found dead at a second scene, bring the toll to 28, authorities said.
The attack, coming less than two weeks before Christmas, was the nation's second-deadliest school shooting, exceeded only by the Virginia Tech massacre that left 33 people dead in 2007.
Panicked parents raced to Sandy Hook Elementary School, about 60 miles northeast of New York City, looking for their children. Students were told to close their eyes by police as they were led from the building.
Schoolchildren — some crying, others looking frightened — were escorted through a parking lot in a line, hands on each other's shoulders.
"Our hearts are broken today," a tearful President Barack Obama, struggling to maintain composure, said at the White House.
Youngsters and their parents described teachers locking doors and ordering the children to huddle in the corner or hide in closets when shots echoed through the building.
A law enforcement official identified the gunman as 20-year-old Adam Lanza, the son of a teacher. A second law enforcement official said his mother, Nancy Lanza, was presumed dead.
Adam Lanza's older brother, 24-year-old Ryan, of Hoboken, N.J., was being questioned, the first official said. Earlier, a law enforcement official mistakenly identified Ryan as the shooter.
Both officials spoke on the condition of anonymity because they were not authorized to speak on the record about the unfolding investigation.
Robert Licata said his 6-year-old son was in class when the gunman burst in and shot the teacher.
"That's when my son grabbed a bunch of his friends and ran out the door," he said. "He was very brave. He waited for his friends."
He said the shooter didn't utter a word.
Stephen Delgiadice said his 8-year-old daughter was in the school and heard two big bangs. Teachers told her to get in a corner, he said.
"It's alarming, especially in Newtown, Connecticut, which we always thought was the safest place in America," he said. His daughter was fine.
Mergim Bajraliu, 17, heard the gunshots echo from his home and ran to check on his 9-year-old sister at the school. He said his sister, who was fine, heard a scream come over the intercom at one point. He said teachers were shaking and crying as they came out of the building.
"Everyone was just traumatized," he said.
Mary Pendergast, who lives close to the school, said her 9-year-old nephew was in the school at the time of the shooting, but wasn't hurt after his music teacher helped him take cover in a closet.
Richard Wilford's 7-year-old son, Richie, is in the second grade at the school. His son told him that he heard a noise that "sounded like what he described as cans falling."
The boy told him a teacher went out to check on the noise, came back in, locked the door and had the kids huddle up in the corner until police arrived.
"There's no words," Wilford said. "It's sheer terror, a sense of imminent danger, to get to your child and be there to protect him."
Obama promised action to prevent such tragedies again but did not say what that would be.
The scene was one of the most outwardly emotional moments of Obama's presidency.
"The majority of those who died were children — beautiful, little kids between the ages of 5 and 10 years old," Obama said.
He paused for several seconds to keep his composure as he teared up and wiped an eye. Nearby, two aides cried and held hands as they listened to Obama.
"They had their entire lives ahead of them — birthdays, graduations, wedding, kids of their own," Obama continued about the victims. "Among the fallen were also teachers, men and women who devoted their lives to helping our children."
