Firefighters made a heroic rescue on Tuesday when a dog fell through the ice on the Mystic River near Boston.
A woman and her two daughters were walking along the Mystic River around 4:30 p.m. with their black lab, Lucy, when officials say Lucy spotted swans in the middle of the river and broke away to run onto the ice. The ice gave way and Lucy plunged into the frigid waters, unable to get herself out.
