(NEWTOWN, Conn.) -- Twenty children died Friday when a heavily armed man invaded a Newtown, Conn., elementary school, after killing his mother at her home and driving to Sandy Hook Elementary and spraying the school with bullets.

The gunman, identified as Adam Lanza, 20, killed himself inside of 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.

Late Friday, police said Nancy Lanza's body was found in the family home. According to sources, Lanza shot his mother in the face, then left the house armed with at least two sem-automatic handguns and a semi-automatic rifle.

State and federal authorities believe his mother may have once worked at the elementary school where Adam went on his deadly rampage, although she was not a teacher, according to relatives, perhaps a volunteer.

Adam Lanza was "obviously not well," a relative told ABC News.

Family friends in Newtown also described the young man as troubled and described his mother Nancy as very rigid. "[Adam] was not connected with the other kids," said one friend.

As part of the investigation authorities searched the New Jersey apartment of Adam's older brother Ryan in Hoboken, New Jersey.

Police had initially identified Ryan as the killer, until he sent out a series of Facebook posts saying it wasn't him and that he was at work all day.

Sources told ABC News that Ryan, 24, works as a senior person in Ernst and Young's tax practice in Manhattan.

"He's a tax guy and he is clean as a whistle," a source familiar with his work said.

Ryan has worked at the firm four years.

Today, the NYPD and FBI went to Ernst & Young and removed Ryan's laptop and other possessions, which is part of the normal investigative process.

Officials were interviewing Ryan and his father, but neither person was under any suspicion, multiple sources said.

Sources said the shooter was armed with a Glock semi automatic handgun and a Sig Sauer semi automatic handgun, law enforcement sources told ABC News. Additionally, .223 caliber shell casings--a rifle caliber--were also found at the scene. He was wearing a bullet-proof vest when he opened fire in the elementary school.

Among the dead in the school was the gunman's mother, who was a teacher's aide, sources told ABC News. Many of the students slain were in class with her when she was killed.

First grade teacher Kaitlin Roig, 29, locked her 14 students in a class bathroom and listened to "tons of shooting" until police came to help.

"It was horrific," Roig said. "I thought we were going to die."

She said that the terrified kids were saying, "I just want Christmas...I don't want to die. I just want to have Christmas."

A tearful President Obama said there's "not a parent in America who doesn't feel the overwhelming grief that I do."

The president had to pause to compose himself after saying these were "beautiful little kids between the ages of 5 and 10." As he continued with his statement, Obama wiped away tears from each eye.

He has ordered flags flown as half staff.

The alert at the school ended when Vance announced, "The shooter is deceased inside the building. The public is not in danger." The massacre prompted the town of Newtown to lock down all its schools and draw SWAT teams to the school, authorities said Friday. Authorities initially believed that there were two gunmen and were searching cars around the school, but authorities do not appear to be looking for another gunman.

It's unclear how many people have been shot, but 27 people, mostly children, are dead, multiple federal and state sources tell ABC News. That number could rise, officials said.

It is the second worst mass shooting in U.S. history, exceeded only by the Virginia Tech shooting in 2007 when 32 were killed before the shooter turned the gun on himself. Friday's carnage exceeds the 1999 Columbine High School shooting in which 13 died and 24 were injured.

The Newtown shooting comes three days after masked gunman Jacob Roberts opened fire in a busy Oregon mall, killing two before turning the gun on himself.

Friday's shooting occurred at the Sandy Hook Elementary School, which includes 450 students in grades K-4. The town is located about 12 miles east of Danbury.

State Police received the first 911 call at 9:41 a.m. and immediately began sending emergency units from the western part of the state. Initial 911 calls stated that multiple students were trapped in a classroom, possibly with a gunman, according to a Connecticut State Police source.

Lt. Paul Vance said that on-duty and off-duty officers swarmed to the school and quickly checked "every door, every crack, every crevice" in the building looking for the gunman and evacuating children.

A photo from the scene shows a line of distressed children being led out of the school.

Newtown Public School District secretary of superintendent Kathy June said in a statement that the district's schools were locked down because of the report of a shooting. "The district is taking preventive measures by putting all schools in lockdown until we ensure the safety of all students and staff," she said.

State police sent SWAT team units to Newtown.

All public and private schools in the town were on lockdown.

"We have increased our police presence at all Danbury Public Schools due to the events in Newtown. Pray for the victims," Newtown Mayor Boughton tweeted.
