Details surrounding the horrific elementary school shooting in Newtown, Connecticut, are still unfolding. With reports that dozens of people are dead — mainly children — authorities are working diligently to comprehend what unfolded.

With accounts of what happened inside Sandy Hook Elementary are just starting to trickle out, MSNBC played video of one young girl sharing her terrifying experience inside of the school:

“I was in the gym and I heard like seven loud booms — and the gym teachers told us to go in the corner so we all huddled. and I kept hearing these booming noises and we all — well we didn’t scream. We started crying, so all the gym teachers told us to go in the office where no one could find us. So, then a police officer came in and told us to run outside, so we did and we came in the fire house and waited for our parents.”
