Parents react

Gina Larkins, who has a daughter in 8th-grade at the Jackson Memorial Middle School, said she was on her way to drop off her daughter who's in 3rd grade when she saw police activity around the middle school.

“I received a phone call from the superintendent that the middle school and high school was on lockdown and all the elementary schools would be closed. I just pulled in waiting to hear further information," said Larkins.

Parents in the area were already on edge this week following the horrific mass shooting at a Florida school.

"I just want to get my daughter and hug her and hold her. I thought it would never happen here but obviously, that is not the case," said Larkins, who was emotional at the thought of what could've happened.

Body armor in book bag

One father whose child goes to the school said he put a piece of armor in his 8th-grade son's backpack over the weekend, in response to the school shooting in Florida.

That father, Don Casey, said a friend who is in support of gun control posted something on Facebook about a man who put regular textbooks in a bag and shot it with a .45, a 9 mm and an assault rifle.

"The handguns didn't go through the first two textbooks. They barely made it through one. I had repainted the shotstop so they gave us this body armor and I put that in my son's book bag."

Student describes moments of uncertainty

The 12-year-old heard teachers screaming to get inside the classroom and the next thing she knew, she was hiding and crouching down with her fellow peers near the teacher's desk.

"I dropped everything. My phone, my chrome book, my book bag and me and my friends ran into the classroom and then we all hid. We were probably there for about 20 minutes," she said.
