FOX Logo-ReducedA gunman opened fire Friday inside Sandy Hook Elementary School in Connecticut, killing 27 people, including 18 children.

Students were told to close their eyes by police as they were led from the building—some were crying, others looked visibly frightened, as they were escorted by adults through a parking lot, holding onto each other’s shoulders.

As the investigation continues, parents across the country are becoming panic-stricken, wondering how they can move forward and feel safer taking their children back to school, a place that many view as a second home for their family.

They may not be able to process information. They may not be able to pay attention or think straight. It’s a way for our emotions to shut everything down because the situation is so horrific we’re not ready to deal with it. “
