Bill Barrett says he and his puppy were out for a walk, searching for seashells on Plum Island Beach, when the leg turned up. "We walked over there, and I said no leave it," the Newbury man tells WCVB. "It was the lower half of the leg with foot still attached, sock on the foot." Police have since cordoned off the area, brought in cadaver dogs, and found more remains that washed up south of the initial find, CBS Boston reports. Officials say police will try to identify the body parts by combing through missing person cases. No word yet on whether the remains belong to a man or woman, but Barrett says that "the sock was big enough that it looked like a guy."
