Gabriel Wheeler described how his teacher at Briarwood Elementary School helped save his and other students lives by putting her hands over children's heads when the ceiling collapsed on top of them.
"It was like the three little pigs, the big bad wolf coming to huff and puff on your house," the teacher, Julie Simon, recalled. "There was this monster coming and we could hear it approaching ... The debris was falling, and we could feel the house was falling across the street. You knew it was coming straight for you."
Gabriel's father, David, says of Simon, "We love her" -- a sentiment echoed by his son.
"She helped save my son's life, she helped save other students' lives, and we're proud of her," David Wheeler said. "She's a member of our family for the rest of our lives."

"I've had 500 text messages from people all over the music world saying what are we doing, we want to help," he said.
