Basson said at 10:40 a.m. that students were about to be released from those classrooms to move on with the rest of their school day.
Police and school officials have not yet been able to identify who wrote the threat, but school resource officers continue to work on it, Basson said.
“We take these types of situations very seriously, even when the threat proves to be non-credible,” she said.

Basson said a “one-call” message was being sent to all parents of high school and those middle school students who were at the high school, explaining the situation.
