Ironton Police Chief Dan Johnson released a statement on Thursday about the ongoing investigation into threats made against Ironton Elementary School.

“Nothing new for release concerning the threat to Ironton Elementary School at this point,” Johnson posted on the IPD’s Facebook page. “Our department must rely on outside agencies to conduct certain aspects of this investigation and we are at the mercy of their time schedule. As soon as we have information that can be released without compromising the investigation we will share that information.”

On Sept. 12 Ironton Schools Superintendent Dean Nance closed Ironton Elementary and Middle schools after a shooting threat was made on the Internet.

This past Tuesday a bombing threat was made against schools in nearby Greenup, Ky., via social media.

“This case and the Greenup County case are very different and unrelated,” Johnson said.

The Associated Press reported on Wednesday an 11-year-old girl has been charged with first-degree terroristic threatening in the Greenup case.

Lawrence County Sheriff Jeff Lawless issued a statement via Facebook about the Ironton and Greenup school threats.

“The Ironton Police Department is heading up the investigation and things are moving forward,” Lawless said. “I was glad to see that the Kentucky officials were able to quickly determine who made the threat against their school. We have been less fortunate as the website we are dealing with is not as cooperative. Everything that can be done is being done.”
