After the police got Roig and her class out of their room, she said she and the children were taken to the nearby fire station, which had been set up as a staging area for parents to come pick up their kids.
That fire house, where Christmas wreaths and poinsettias are for sale, has been turned into a place of grief where frantic parents were either reuniting with their children or learning that their children are dead, or were still waiting for word.
Children stared wide-eyed as they watched state police troopers in body armor, holding raised rifles, quickly rush to secure the scene at their school. Parents said they had never been so panicked. One father, hoping to preserve a semblance of innocence, shielded his son's eyes with his forearm.
Wasik's mother said she found out about a shooting through the school's alert system, which sent her a message about a lockdown, and is still in disbelief.
"It just doesn't seem real," she said. "It feels like a nightmare. You drop your kids at school, hugs and kisses, have a good day, I'll see you later and see you at the end of the day and you never know.. in 20 minutes from now what's going to happen. And you count your blessing everyday for what you have."
