"From the classroom we seen through the window," said Nalya Woll, a junior at Binghamton High School. "I've seen the sniper out on the roof. It was just scary. We've seen the hostages come out they had white wrapped around them. It was just pretty traumatic."

"It was bad because I didn't know how she was like I was scared," freshman Maria Colom said. "I was crying but as soon as they let us know that the guy got caught I was happy to know that but I still don't know if she's dead or not."

"It was nervous for all of us and we had people coming to the doors. We had to tell them that we were on lockdown and they were visitors and we still couldn't let them in," said Julie Breid of Binghamton.
