Dawn Hochsprung, 47, principal

(AP) -- Dawn Hochsprung's pride in Sandy Hook Elementary was clear. She regularly tweeted photos from her time as principal there, giving indelible glimpses of life at a place now known for tragedy. Just this week, it was an image of fourth-graders rehearsing for their winter concert; days before that, the tiny hands of kindergartners exchanging play money at their makeshift grocery store.

She viewed her school as a model, telling The Newtown Bee in 2010 that "I don't think you could find a more positive place to bring students to every day." She had worked to make Sandy Hook a place of safety, too, and in October, the 47-year-old Hochsprung shared a picture of the school's evacuation drill with the message "safety first." When the unthinkable came, she was ready to defend.

Officials said she died while lunging at the gunman in an attempt to overtake him.

"She had an extremely likable style about her," said Gerald Stomski, first selectman of Woodbury, where Hochsprung lived and had taught. "She was an extremely charismatic principal while she was here."
