BRUNSWICK, Maine — A Maine duck hunter was rescued Wednesday after he went to retrieve the birds he shot and became stuck in deep mud, police said. He had been standing on the bank when he shot several ducks, but when he walked across the mud to retrieve them, he started sinking. Topsham was “unable to move, and the more he struggled, the deeper he became,” police said. Officers responding to the scene found Topsham waist-deep in the mud. Police said it took two officers to “pull and break the suction” to free Topsham from the mud.
