According to the book, "Weird New England," Bigfoot sightings have also occurred in the swamp. The book contends that the creatures are generally calm, but that at one point in the 1970s, one went "haywire," killing pigs and sheep belonging to local farmers. Police with attack dogs searched the swamp for two days, but found no sign of the Bigfoot creature.
