>> shepard: casey stegall on scene. casey, we are still watching from above as they work frankly much more slowly than before in the wreckage of this elementary school i don't have to tell you has been devastated. very little left here except for what the authorities have told the nbc station is a search and recovery mission. there are scenes like this playing out all over this town it's our belief. of course, the choppers hover. house after house after house stories unbelievable day and more. our coverage continues after this.
