Editor: An open letter to the citizens of Statesboro and Bulloch County: On Wednesday of this past week, Georgia Southern University experienced a potential hazardous substance threat on our campus. The office of admissions, located in Lewis Hall on Sweetheart Circle, received a package via UPS that, when opened, contained traces of a white powdery substance. The university’s emergency response plan was immediately implemented, and within a matter of minutes, representatives from the local, area, state and federal law enforcement agencies arrived to monitor the situation.
