Officials are identifying the principal as one of the victims in the Connecticut elementary school rampage.
Gerald Stomski is the first selectman of Woodbury, Conn. He says police told him that Sandy Hook Elementary Principal Dawn Hochsprung was among the 26 people the gunman shot to death at the school Friday.
He says she was a principal in Woodbury until a few years ago. He says residents were mourning her death.
Stomski says she had "an extremely likable style."
Hochsprung had been principal at Sandy Hook Elementary since 2010. Hochsprung had frequently tweeted photos from her job and wrote upbeat tweets about what was going on at the school.
More hauntingly, several publications report she wrote a letter before the school year outlining new safety measures including locked doors during school hours.
WASHINGTON (AP) - A law enforcement official says some guns owned by the mother of the gunman in the Connecticut elementary school rampage match the models of the guns used in the shooting.
The official cautions that investigators haven't conclusively linked the guns used in the rampage to the ones the woman owned.
The official says state police records show the woman had legally purchased five firearms and all were registered in Connecticut. Authorities are still trying to account for all the guns.
The official was not authorized to speak to reporters about the investigation and spoke only on condition of anonymity.
Authorities say the woman's 20-year-old son killed her Friday, then opened fire inside the school in Newtown, massacring 26 people, including 20 children, then killed himself.
Police aren't say what may have motivated a man to open fire inside two classrooms at a Connecticut elementary school today, but a law enforcement official who has been briefed on the investigation says the gunman was believed to suffer from a personality disorder
Twenty-six people, including 20 children, were killed in the shooting rampage before the gunman shot and killed himself. Police say another adult was found dead at a second location.
A law enforcement official has identified the gunman as 20-year-old Adam Lanza, the son of a teacher at the Sandy Hook Elementary school. The official says Lanza killed his mother at their home before driving his mother's car to the school.
Police say the killer carried two handguns into the school, while a rifle was found in the back of a car. They say the shootings took place in two classrooms, but they are not providing details on exactly how it unfolded.
Students and their parents describe teachers locking doors and ordering the children to huddle in classroom corners or hide in closets as shots echoed through the building. Authorities said the shootings took place in two nearby classrooms, but they gave no details on exactly how they unfolded.
A law enforcement official briefed on the investigation of the Connecticut school massacre says the brother of the gunman has been "extremely cooperative" and is not under arrest.
The official tells The Associated Press that Ryan Lanza, of Hoboken, N.J., is still be being questioned but is not in custody and is not believed to have any connection to the school killings.
The official spoke on condition of anonymity because he was not authorized to speak publicly on the investigation.
The official says Ryan Lanza's computers and phone records were being searched but only "in an abundance of caution." He says Ryan told authorities he had not been in touch with his brother in recent years.
A law enforcement official says the suspect in the Connecticut school shootings is 20-year-old Adam Lanza, the son of a teacher at the school where the shootings occurred. A second law enforcement official says the boy's mother, Nancy Lanza, is presumed dead.
The first official says Adam Lanza's older brother, 24-year-old Ryan, of Hoboken, N.J., is being questioned by police. An earlier report from a law enforcement official mistakenly transposed the brothers' first names.
Both officials spoke on the condition of anonymity because they were not authorized to speak on the record about the developing criminal investigation.
The first official said Adam Lanza is dead from a self-inflicted gunshot wound.
An official with knowledge of a shooting at a Connecticut elementary school says 27 people are dead, including 18 children.
The official spoke on condition of anonymity because the investigation is still under way.
Another official, speaking on condition of anonymity for the same reason, says the gunman is among the dead.
The killings happened at Sandy Hook Elementary School in Newtown, about 60 miles northeast of New York City.
State police say Newtown police called them around 9:40 a.m. A SWAT team was among the throngs of police to respond.
Photos from the scene showed young students -
some crying, others looking visibly frightened -- being escorted by adults through a parking lot in a line, hands on each other's shoulders.
