It was tough for many parents across the country to send their kids back to school today, but for some parents in Russell County, Virginia it was even harder, because of a Facebook comment.

"I debated really whether to send my son to school or not, you know, because it's kind of frightening to put your kid on a bus and not really know if you're going to see them get off the bus," said Katherine Johnson, a mother whose children go to Russell County schools.

Russell County Superintendent of Schools, Brenda Hess, declined an interview, but told us this in a written statement:

"There was a threat posted on Friday night via Facebook alleged to have been made by a Lebanon High School student.  In the message, the Connecticut Elementary School shooting and Lebanon Elementary School were referenced..."

We sat down with Russell County Sheriff Steve Dye. He told us the comment was more 'inappropriate' than threatening, but it's not being overlooked.

"The individual was picked up and detained," he said.

The sheriff emphasized that students were never in any danger, but when it comes to kids, he said you can never be too careful.

"Anytime there's an issue involving any of the schools, I would always prefer to over-respond as to under-respond," said Sheriff Dye.

That's why Monday there were increased patrols outside and inside Russell County schools.    

It's something we're told the sheriff's department would have done anyway following Friday's tragic events for reassurance, but it's a relief to parents still wanting to hold on tight to their kids.

"It does put my mind at ease, because I know they are really good people, and they are dedicated to the safety of everybody," Johnson added.

We learned this juvenile suspect in this case is charged with making a threat.

Sheriff Dye said the student had a hearing Monday and was put back in juvenile detention with another hearing set for early next month.
