Newtown begins heartbreaking process of saying goodbye

At a time when Newtown should be reveling in holiday cheer, the grief-stricken community is beginning the grim task of lowering little coffins into the ground.

Newtown, Conn.

At a time when Newtown should be reveling in holiday cheer, the grief-stricken community is beginning the grim task of lowering little coffins into the ground.

Children were among the mourners at 6-year-old Jack Pinto's funeral.

Noah Pozner, another 6-year-old whose family said he could get what he wanted just by batting his long eyelashes, will also be buried.

And the heartbreaking ritual will continue for days.

Jessica Rekos on Tuesday. Benjamin Wheeler on Thursday. Madeleine Hsu, Friday. All of them 6 years old.

But even after the families of the 20 children and six educators killed at Sandy Hook Elementary School say their last goodbyes, it's unlikely that the tight-knit Connecticut community will ever be the same.

"It's incomprehensible, the pain here," resident Darla Henggeler said. "You can't imagine. We're still in shock. I can't let my heart go there because it's so overwhelming.

"I think once it settles in, I think my heart will break."

Clues about what happened, but not why

It's possible that no one will ever know what led gunman Adam Lanza to kill his mother, Nancy, in their home before taking her guns and raining hell on Sandy Hook Elementary School and eventually killing himself.

"There was no connection between the shooter and the school," Connecticut State Police Lt. J. Paul Vance said Monday, citing school authorities in Newtown.

But one mother told CNN Monday that the gunman was once a student at Sandy Hook. Cynthia Jaroszewksi said the shooter was in first and third grade there with her daughter, Rebecca.

As the investigation continues, two wounded adults who survived the shooting could play a key role in helping reconstruct what happened, Vance said.

The adults "were wounded in their lower extremities" and are recovering from their injuries, Vance told reporters. Investigators will not release their names, he said, because they are witnesses in the case.

Earlier, Vance had said only one person was injured in the shooting. A parent who was at Sandy Hook during the shooting said Friday that the school's vice principal was injured. The second wounded survivor's identity was unclear Monday.

"Our investigators will, in fact, speak with them when it's medically appropriate," Vance said, "and certainly they will shed a great deal of light on the facts and circumstances of this tragic investigation."

Authorities were searching smashed computer parts seized from the gunman's home for clues that might shed light on the shooting, including e-mails he might have sent and websites he might have visited, a law enforcement official said Monday.

Officials were tight-lipped about details of their investigation. Hundreds of troopers, detectives and other police are piecing together clues, Vance said, analyzing every round of ammunition and every weapon, in addition to every detail of the gunman's medical history.

"I'm not at liberty to discuss any of the information so far uncovered, but suffice it to say ... we will cover every single facet," he said.
