The only survivor of one of the two Sandy Hook Elementary School first-grade classrooms where Adam Lanza shot and killed 20 children tricked the gunman by playing dead,the girl’s pastor(牧师)said.

“She ran out of the school building covered from head to toe with blood and the first thing she said to her mom was,“Mommy,I’m OK but all my friends are dead” Pastor Jim Solomon told ABC News’ Lara Spencer this weekend

“Somehow,at that moment, by God’s grace,she was able to act as she was already dead.”he said.

The girl, a 6-year-old whose name is not being announced for privacy(隐私)reasons,was the first student to appear from the lockdown(封锁)at Sandy Hook,Solomon said.He said the young girl described the shooter to her mom in a way that only a young child can.

“Well, she saw someone who she felt was angry and someone she felt was very mad,”Solomon said. “I think it's impossible without the help of God. She has wisdom beyond her years, for sure’’

Of the 20 children killed on Friday in the Newtown,Conn., school, eight were boys and l2 were girls Six staff members,all female, were also killed. The gunman,whose mother was also killed by him before he went to the schoo1 classrooms, was found dead at the present spot.

“The mom told me—and I thought this was very insightful(有深刻见解的)—that she was suffering from what she felt was survivor’s guilt because so many of her friends no longer have their children but she has hers,” Solomon said how the girl’s mother and father are handling the trauma(伤害).“I don’t know whether l would have the type of faith that they have if the same thing happened to me.”
