As far as I can tell, there were no bomb threats at any schools in Ohio today. There was one yesterday at Wadsworth High School, which could possibly be the one Jamer goes to, but it's about 2.5 hours away from the location of his ISP.
I find it hard to believe that a bomb threat at a school would fail to be reported in any news outlet whatsoever. I realize it probably wouldn't make national news, but local news stations would publish it just because it's a relatively big story and parents and other people in the community need to know about it.
