MEMPHIS, Tenn. -- Thursday was a scary day for kids at Ross Elementary School, where a man showed up with a loaded gun.

Police said it was a domestic fight between parents of a student there.

No kids or faculty were hurt, and even though the man who brought the gun is in custody, plenty of kids were still shaken.

Amber Wilson, a fourth-grader, said, "I thought something bad was going to happen."

Emotions ranged from timid and scared to blissfully innocent and unaware.

Fifth-grader Joshua Davis said simply, "I was just eating some Oreos when my teacher told us we can. Then, I got on the computer and played Bingo!"

However, parents of Ross Elementary students understood all too well the danger their babies were in. Jacque Townsend's son goes to the school.

"The Sandy Hook thing...that's what went through my head, kids getting killed," he said, his eyes tearing up. "I didn't want that to happen here at Ross Elementary. So, it was scary."

Police said a man and woman got into a fight at the school over their child.

The man was carrying something you hope to never see on the school campus.

"We have located a gun inside the school," Memphis Police Director Toney Armstrong said. "The gun was fully loaded."

When police arrived, the man tried to run.

Eric Wilson, a second-grader, said he saw him.

"I looked in the window in my classroom, and I saw somebody running by the outside door. I thought it was the person that broke in," he said.

Armstrong said, "They had a physical fight with that individual. The fight started inside of the school and spilled out into the parking lot. Officers deployed a chemical agent to subdue the suspect and eventually, he was arrested."

Kids said their teachers locked classroom doors and tried to keep them calm.

"She was trying to protect everybody," Amber Wilson said of her teacher. "We couldn't eat lunch at the time, so she had a bucket full of stuff that we could eat and gave it to us."

Now that parents have their kids back in their arms, some worry Halloween, a day dedicated to spooks and scares, may be too much for these little ones to handle.

Parent Adrevia Carmichael said, "People are already going to have on their scary costumes, and then she's already had a real-life incident with a gun involved. So now it's going to be like everyone is a monster."

So far, police have not released the name of the suspect.
