(Oxford, OH)--At just after 2 o’clock Thursday afternoon, messages were sent to Miami University students telling them to "run, hide, fight" based on a report of a potential active shooter.  "We did have students sheltering in place and calls coming from the building.  We went ahead and issued the campus alert," said Miami’s police chief in talking  about something sounding like gunshots outside of McGuffey Hall.  Miami later gave the all clear after finding no evidence of gunfire or anyone injured.  The sounds are believed to have been fireworks.
