FORT KENT, Maine — Family members who lost their Fort Kent home and almost all of their belongings to fire on Saturday were able to retain a precious part of their heritage due to an unlikely set of circumstances that occurred three days earlier, when a woman found a small urn on a shelf at a local store. Sandy Tagget of Fort Kent was shopping at the town’s Rite Aid on Wednesday afternoon when she came across an ornate, silver-colored urn containing ashes on a shelf in the toy aisle. At the suggestion of Rite Aid managers, Taggett brought the urn with the possibly human ashes to the Fort Kent police station.
