Claremore Police said they were able to trace the blocked call back to Montgomery and when investigators confronted her, she confessed to calling in the bomb threat. Montgomery was arrested for making a terroristic threat.
"I don't think people who weren't here know the disruption that this caused, not just to our schools but to our city," Claremore Police Deputy Chief Steve Cox said.
Deputy Chief Cox said the threat allowed them to test their emergency plan.
"I hated that we had to go through that for our children," Deputy Chief Cox said. "That is something that we will learn from too. The schools will learn from and going forward it will make us even better."
He said they plan to get together with the involved agencies and review the response.
Overall, Deputy Chief Cox said they believe it went well.
"We had local community members from our churches from local businesses to just private citizens showing up at our three location sites providing food, providing snacks," Deputy Chief Cox said. "This was not even something we asked for. They reached out to us."
Claremore Public Schools said they will have classes Wednesday.
Police said Montgomery was booked into the Rogers County Jail later Tuesday evening. Her bail was set at $100,000 and she will appear in court on April 10.
