Police, firefighters, HazMat units, mobile labs, the National Guard, the state police and the FBI turned out May 12 in response to a report of a white, powdery substance falling out of an envelope at Bar Harbor Bank & Trust’s operations center May 12. Investigation showed that the substance was not hazardous, but investigators have been unable to identify the material, in part because there wasn’t much to test. — ELLSWORTH AMERICAN PHOTOS BY CYNDI WOOD
