NEWTOWN, Conn. -- State Police Lt. J. Paul Vance, during a morning news conference in Newtown, told reporters from around the nation and from overseas that 20-year-old Adam Lanza forced his way into the building prior to the shooting.
"I can tell you it's believed he was not voluntarily let into the school at all, that he forced his way into the school, but that's as far as we can go on that," Vance said.
He said that responding police forced their way into the school and "broke many windows."
Between the school and Lanza's mother's house on Yogananda Street, where she was found dead, Vance said there was "very good evidence in this investigation that our investigators will be able to use in hopefully painting the complete picture as to how and more importantly why this occurred."
He declined to detail the evidence.
"I just simply want you to understand that we still have Major Crime detectives and Newtown detectives working at the scene in the school," he said. "That is not completed. That probably will not be completed for at least another day and a half to two days. I'm not putting a time limit on it. It could take longer. As I explained to you at previous press conferences we've done everything we need to do to literally peel back the onion, layer by layer, okay and examine every crack and crevice of that facility and that does not exclude the outside of the building."
Vance said there are three major crime teams in the town. The Chief Medical Examiner was still in the process of identifying victims and as soon as he is finished, Vance said identities will be announced.
At least two handguns and an assault-style rifle were involved in the murders.
"The weaponry that was recovered by our investigators was discovered in close proximity of the deceased," Vance said.
