A male body has been found in the area of Spicer's Marina in the Noank section of Groton, authorities said.
USCG officials said the body, which was found tangled in some lines late Wednesday morning, is that of an "older" male. They do not believe it is related to the recent missing boaters crews were searching for over the weekend.
Groton Town Police said the case does not appear suspicious and is being treated as an untimely death investigation.
Police are working to identify the body and locate next of kin.
No other information was immediately available.
