Everyone was just traumatized, he said.
Richard Wilfords 7-year-old son, Richie, is in the second grade at the school. His son told him that he heard a noise that sounded like what he described as cans falling.
The boy told him a teacher went out to check on the noise, came back in, locked the door and had the kids huddle up in the corner until police arrived.
Theres no words, Wilford said. Its sheer terror, a sense of imminent danger, to get to your child and be there to protect him.
