Out of respect for the Newtown victims and their families, Dick's Sporting Goods has removed all guns from its store closest to Newtown, the company said.
Dick's, one of the largest sporting goods retailers in the world, also has suspended the sale of some semiautomatic rifles nationwide, the company said.
It was unclear how long Dick's will keep its suspension of "modern sporting rifles."
For Sandy Hook kids, no school until January
The current plan is for the children to resume school in January at the former Chalk Hill Middle School, eight miles away in neighboring Monroe, Newtown Superintendent of Schools Janet Robinson said in a letter to parents.
"We need to tend to our teachers' and students' needs to feel comfortable after this trauma in this new place," she wrote.
Teachers may call parents "to invite you to visit Chalk Hill with your child this week to walk around and see the classroom and get familiar with this new Sandy Hook home."
At least two more victims, 6-year-olds Jessica Rekos and James Mattioli, had burials scheduled for Tuesday.
Across town, hearses can be seen traveling along roads with police escorts. Some have tiny coffins. Onlookers break down crying at the sight.
The gunman's computer
Investigators have so far been unable to retrieve data from a computer taken from the home of the gunman, Adam Lanza, a law enforcement official said Tuesday.
It appears that Lanza had smashed the computer, extensively damaging the hard drive, the official said, adding that the FBI is assisting Connecticut State Police in trying to retrieve data from the computer.
Grim new details
Lanza's mother was shot four times in the head while she slept in her bed, Connecticut Chief Medical Examiner H. Wayne Carver said Tuesday.
Adam Lanza killed himself with a shot to the front of his head from a handgun, the medical examiner said.
Toxicology tests are under way to determine whether Adam Lanza had taken medicines, Carver said.
Shedding new light on the gunman
While Carver said he was told that Adam Lanza had Asperger's syndrome, officials are working to determine whether that diagnosis was correct, and whether he may have had other diagnosable problems.
A former director of security for Newtown Public Schools shed new light Monday night on the gunman, Adam Lanza.
Richard Novia said Lanza had Asperger's syndrome, based on documents and conversations with Lanza's mother, who was killed shortly before the Sandy Hook massacre.
Novia said that as part of his job, which he left in 2008, he would be informed of students who might pose problems to themselves or others.
He also said he received "intake information," which he said "is common for any students troubled or impaired or with disabilities." The idea was to keep track of and help students who may need it.
However, Novia said he never thought Lanza was a threat and certainly never thought he was capable of such violence.
Russ Hanoman, a friend of Lanza's mother, previously told CNN that Lanza had Asperger's and that he was "very withdrawn emotionally."
CNN has not been able to independently confirm whether Lanza was diagnosed with autism or Asperger's, a higher-functioning form of autism. Both are developmental disorders, not mental illnesses.
