The Coast Guard says 20-year-old Benji Aven was swimming from Salt Island to Westbrook early Monday when he vanished. Coast Guard officers were notified of his disappearance late Monday morning and began searching for him.
Other local and state emergency responders have joined in the search. They haven't found Aven yet. His hometown wasn't available.
The Coast Guard says the waters of the Long Island Sound can be especially hazardous at night.
