December 20, 2012, 7:07 amThere have been a number of mysterious threats about school shootings around Oregon and SW Washington. But school districts and police say there is no credible threat. Schools like Reynolds High School will add extra security today. Parents were contacted by the district as they left last night's Christmas concert. Lincoln County schools will close all their classrooms today because of online threats. The same goes for Jefferson County and the Banks School District in Washington County.
