NEWTOWN, Connecticut (AP) -- A grieving Connecticut town braced itself Monday to bury the first two of the 20 littlest victims of the school gunman. Authorities could not say when or whether the school, now a crime scene and forever a place of tragedy, would reopen.
State police Lt. Paul Vance said that it could be months before police turn Sandy Hook Elementary School back over to the district. The people of Newtown, consumed by loss, were not ready to address its future.
"We're just now getting ready to talk to our son about who was killed," said Robert Licata, the father of a student who escaped harm during the shooting. "He's not even there yet."
Classes were canceled Monday, and Newtown's other schools were to reopen Tuesday. The district made plans to send surviving Sandy Hook students to a former school building in a neighboring town but could not say when.
On Sunday, President Barack Obama pledged to seek change in memory of the 20 children and six adults slain Friday by a gunman packing a high-powered rifle. The president slowly recited the first names of the children.
"What choice do we have?" he said. "Are we really prepared to say that we're powerless in the face of such carnage, that the politics are too hard?"
Authorities said Sunday that the gunman, 20-year-old Adam Lanza, was carrying an arsenal of hundreds of rounds of especially deadly ammunition, enough to kill just about every student in the school if given enough time.
The shooter decided to kill himself when he heard police closing in about 10 minutes into the attack, Connecticut Gov. Dannel P. Malloy said Sunday on the ABC program "This Week."
The first funerals were for two 6-year-olds: Jack Pinto, a year-old New York Giants fan who might be buried in wide receiver Victor Cruz's jersey, and Noah Pozner, who liked to figure out how things worked mechanically. His twin sister, Arielle, who was assigned to a different classroom, survived the shooting.
"He was just a really lively, smart kid," said Noah's uncle Alexis Haller, of Woodinville, Wash. "He would have become a great man, I think. He would have grown up to be a great dad."
With more funerals planned this week, the road ahead for Newtown, which had already started purging itself of Christmas decorations in a joyful season turned mournful, was clouded.
"I feel like we have to get back to normal, but I don't know if there is normal anymore," said Kim Camputo, mother of two children, 5 and 10, who attend a different school. "I'll definitely be dropping them off and picking them up myself for a while."
Jim Agostine, superintendent of schools in nearby Monroe, said plans were being made for students from Sandy Hook to attend classes in his town this week.
Newtown police Lt. George Sinko said he "would find it very difficult" for students to return to the same school where they came so close to death. But, he added, "We want to keep these kids together. They need to support each other."
Connecticut Education Commissioner Stefan Pryor said state construction employees are giving their advice on renovating Sandy Hook, which serves grades kindergarten through four.
It wasn't just Newtown concerned about the next steps for its schoolchildren. Across the country, vigilance was high.
In an effort to ensure student safety and calm parents' nerves, school systems asked police departments to increase patrols and sent messages to parents outlining safety plans they said are regularly reviewed and rehearsed.
Teachers girded themselves to be strong for their students and for questions and fears they would face in the classroom.
"It's going to be a tough day," said Richard Cantlupe, an American history teacher at Westglades Middle School in Parkland, Fla. "This was like our 9/11 for schoolteachers."
Communities were on edge. In nearby Ridgefield, Conn., schools were locked down after a suspicious person was seen near a train station.
At an interfaith service in Newtown on Sunday evening, Obama said he would use "whatever power this office holds" to work with law enforcement, mental health professionals, parents and teachers to prevent more tragedies like Newtown.
The president met privately with families of the victims and with the emergency personnel who responded to the shooting. Police and firefighters got hugs and standing ovations when they entered for the public vigil, as did Obama.
"We needed this," said the Rev. Matt Crebbin, senior minister of the Newtown Congregational Church. "We need to be together here in this room. ... We needed to be together to show that we are together and united."
As Obama read some of the names of victims early in his remarks, sobs resonated throughout the hall. He closed by slowly reading the first names of each of the 20 children.
"God has called them all home," he said. "For those of us who remain, let us find the strength to carry on and make our country worthy of their memory."
Authorities say the gunman shot his mother, Nancy Lanza,
