HARRIMAN, Tenn. (WVLT) -- No court date yet and no bond for the 15-year-old who planned to kill another student at Harriman High School Thursday.

The teen allegedly confessed his plan when confronted by the principal and school resource officer in the cafeteria.

"It could have been very tragic, and who knows what could have happened?" Roane County Board of Education member Franklin Mee said.

A day after the sophomore was arrested, his fellow students continued their normal routine.

"It was a little scary," mother Jamie Wilmouth told Volunteer TV.

"I didn't hear anything from the school, or from my daughter," Wilmouth explained.
"A friend of mine got a message that they had a lock down. It wasn't an accurate message, but it was a message," she continued.

Wilmouth says she got most of her information from the news.
Mee says he found out by word of mouth.

"It was sort of a rumor. Someone was coming in saying, 'They had an incident at the high school', " Mee said.

The incident started over a girl.
The Roane County Sheriff's office told us the accused gunman decided he was going to end the problem with a gun.

"He evidently had his pistol in a hoodie," Mee explained.

Before school began, the teen bragged about his plan. Some concerned students took the threat seriously and passed on the information.

Principal Russel Jenkins approached from the front.
The school resource officer came up from behind.

"He had it laying on the table right in front of him and Mr. Jenkins just put his hand on it and said 'We need to go to the office and talk', " Jenkins said.

From there, they say he admitted he brought the loaded gun to shoot another student, then himself.

But that never played out.
Instead, the student was arrested.

Wilmouth says she doesn't want to be the last to know if something like this happens again.

"I did find out there's a way to get text alerts. And, I signed up for it immediately following it," she laughed.

The principal refused to talk to us about the situation today, saying he was worried about copy cats.

The director of schools did not return our calls.

Investigators tell us the juvenile system is going to try to figure out how a student-- who has never been in trouble before-- got to the point where he decided to use a gun to solve his problems.
