-snip- One of those killed, first-grade teacher Victoria Soto, died after hiding her students, a source told The Courant. Soto was a teacher in room 10, the classroom next to where the shooting began, the source said. She hid her students — 15 or 16 of them, some possibly in a bathroom — before the gunman entered the room. He wanted to shoot more people, the source said, but, seeing no one but Soto, he shot her, then left the room, the source sad.
