Connecticut investigators released more details into how the horrific tragedy at Sandy Hook Elementary School unfolded last Friday. The shooter's rampage lasted all of 10 minutes but has forever changed the community of Newtown.
During those 10 minutes, 20 children and six adults were shot and killed. All them were shot multiple times with a high-power rifle, some of them up close.
Connecticut State Police Lt. Paul Vance said gunman Adam Lanza shot through the glass near the front door and forced his way in through the opening. Once inside, sources told Eyewitness News he shot principal Dawn Hochsprung and school psychologist Mary Sherlach. Both women rushed toward Lanza in an attempt to stop him and paid with their lives.
According to sources, Lanza then went into substitute teacher Lauren Rousseau's classroom and shot her and all 14 children. He then went into Vicky Soto's class. She was able to hide seven of her children in a closet. But Lanza shot her and six of her students while she was trying to shield them.
Police said Lanza shot himself in the head when he heard sirens from the first officers arriving on scene.
Sandy Hook Elementary School and Lanza's home will remain a crime scene indefinitely. Lanza shot his mother, Nancy, at the home he shared with her before going on the shooting rampage at Sandy Hook.
Investigators found smashed computer parts at the Lanza home and have sent them to Washington, DC, in hopes that federal investigators will find clues that might shed light on the shooting. They are also looking at emails the gunman might have sent and websites he might have visited, a law enforcement official said Monday.
Investigators are also hoping to find any surveillance video that may have been captured of the gunman in the weeks or days leading up to the shooting that could offer clues.
Authorities said Lanza had no criminal history, and it was unclear whether he had a job.
Federal authorities visited local gun ranges but found no evidence that the gunman trained for the attack or was an active member of the recreational gun community. Investigators also have interviewed gun dealers trying to determine whether there was any training or other behavior that precipitated the attack.
The Associated Press reports that Lanza was described as a bright but painfully awkward student who seemed to have no close friends. In high school, he was active in the technology club. The club adviser remembered that he had "some disabilities" and seemed not to feel pain like the other students. That meant Lanza required special supervision when using soldering tools, for instance. He also had an occasional "episode" in which he seemed to withdraw completely from his surroundings, the adviser told The Associated Press.
