A string of bomb threats reported across the country Thursday appear to be hoaxes, but they still caused problems at several locations coast to coast. Missouri was not excluded. Several locations across the state reported receiving the threats, including at least one school in the lake area. The School of the Osage says a staff member at the middle school received an email threat near the end of the school day. School officials said they followed all procedures for such an instance. That included contacting local, state, and federal law enforcement agencies. A sweep of the school was conducted with no evidence of a credible threat found.
