“I don’t think they understand the severity and magnitude of these comments,” said Nicole Bailey as she dropped her child off at the school.
Action News Jax called Duval County Public Schools – a spokesperson refused an interview about the issue.
They said they share parents' frustration, but pointed out that other schools have also seen multiple threats.
In Mandarin High School received 2 threats in less than 24 hours.
Action News Jax Crime and Safety Expert Ken Jefferson said customizing the code of conduct for threat prone schools would help.
Bailey explained, “It’s sad, it’s heartbreaking that these students have to go through this.”
On Friday, district leaders say they have been ale to track down and discipline people responsible for some of the threats – they would not specify which situations.
