Danbury School Superintendent Kevin Walston says the district received a call this morning reporting that shots were fired in the vicinity of Danbury High School.  Walston says they have found no actual evidence that this has occurred, nor do they have any evidence that a gun was on campus.  Police have met with the student driving the reported car, but nothing has been substantiated.   Out of an abundance of caution the school temporarily went into shelter in place, but that has since been lifted.  The investigation is continuing.
