Victoria Soto, 27, teacher

(AP) -- She beams in snapshots. Her enthusiasm and cheer was evident. She was doing, those who knew her say, what she loved.

And now, Victoria Soto is being called a hero.

Though details of the 27-year-old teacher's death remained fuzzy, her name has been invoked again and again as a portrait of selflessness and humanity among unfathomable evil. Those who knew her said they weren't surprised by reports she shielded her first-graders from danger.

"She put those children first. That's all she ever talked about," said a friend, Andrea Crowell. "She wanted to do her best for them, to teach them something new every day."

Photos of Soto show her always with a wide smile, in pictures of her at her college graduation and in mundane daily life. She looks so young, barely an adult herself. Her goal was simply to be a teacher.

"You have a teacher who cared more about her students than herself," said Mayor John Harkins of Stratford, the town Soto hailed from and where more than 300 people gathered for a memorial service Saturday night. "That speaks volumes to her character, and her commitment and dedication."
