Principal killed while lunging at Connecticut gunman; names and ages of victims released
After what she guessed was about an hour, officers came to the door and knocked, but those inside couldn't be sure it was the police.
"One of them slid his badge under the door, and they called and said, 'It's OK, it's the police,'" she said.
The district superintendent said she was told another teacher pushed students in the kiln room until police let them out.
Investigators believe Lanza attended the school several years ago but appeared to have no recent connection to it, a law enforcement official speaking on condition of anonymity said. It was not clear whether he held a job.
At least one parent said Lanza's mother was a substitute teacher at the school. But her name did not appear on a staff list. And the official said investigators were unable to establish any connection so far between her and the school.
The law enforcement officials insisted on anonymity because they were not authorized to discuss the unfolding investigation.
Lanza's older brother, 24-year-old Ryan Lanza, of Hoboken, N.J., was questioned, and investigators searched his computers and phone records, but he told law enforcement he had not been in touch with his brother since about 2010.
For about two hours late Friday and early Saturday, clergy members and emergency vehicles moved steadily to and from the school. The state medical examiner's office said bodies of the victims would be taken there for autopsies.
The gunman forced his way into the kindergarten-through-fourth-grade school, authorities said. He took three guns into the school — a Glock and a Sig Sauer, both semiautomatic pistols, and a .223-caliber Bushmaster rifle, according to an official who spoke on the condition of anonymity. The weapons were registered to his slain mother.
Lanza and his mother lived in a well-to-do part of prosperous Newtown, about 60 miles northeast of New York City, where neighbors are doctors or hold white-collar positions at companies such as General Electric, Pepsi and IBM.
His parents filed for divorce in 2008, according to court records. His father, Peter Lanza, lives in Stamford, Conn., and works as a tax director for GE.
The gunman's aunt Marsha Lanza, of Crystal Lake, Ill., said her nephew was raised by kind, nurturing parents who would not have hesitated to seek mental help for him if he needed it.
"Nancy wasn't one to deny reality," Marsha Lanza said, adding her husband had seen Adam as recently as June and recalled nothing out of the ordinary.
Catherine Urso, of Newtown, said her college-age son knew the killer. "He just said he was very thin, very remote and was one of the goths," she said.
Lanza attended Newtown High School, and several news clippings from recent years mention his name among the honor roll students.
Joshua Milas, who graduated from Newtown High in 2009 and belonged to the school technology club with him, said that Lanza was generally a happy person but that he hadn't seen him in a few years.
"We would hang out, and he was a good kid. He was smart," Joshua Milas said. "He was probably one of the smartest kids I know. He was probably a genius."
The mass shooting is one of the deadliest in U.S. history, and among school attacks is second in victims only to the 2007 Virginia Tech massacre, which left 33 people dead, including the gunman. Reaction was swift and emotional in Newtown and beyond.
"It has to stop, these senseless deaths," said Frank DeAngelis, principal of Colorado's Columbine High School, where a massacre in 1999 killed 15 people.
