(CNN) — Investigators are searching smashed computer parts for clues that might shed light on the Connecticut school shooting, including e-mails gunman Adam Lanza might have sent and websites he might have visited, a law enforcement official said Monday.
The official did not know how many computers were seized from the home where Lanza lived, but thinks there was more than one.
A second law enforcement official said investigators had removed computers from the house, but would not comment on their condition.
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.”
