A Topsham man had to be rescued on Wednesday afternoon after he became stuck up to his waist in coastal mud in Brunswick. Alexander told emergency dispatchers he had shot several ducks from the shore, and when he went to retrieve them he suddenly sank. Brunswick police officers used their department’s Marine Patrol air boat to reach Alexander. It took two officers to break the suction and get Alexander into the boat, according to the department. The Brunswick Police Department cautioned that coastal mudflats are unstable and can have “honey pots” that act like quicksand — the more a person moves, the deeper they sink.
