It was a beautiful September day, just right for a boat trip, thought Mystic Island resident Fred Schaffer as he powered his craft through his lagoon and out to Great Bay. His wife, Marge, and a fishing buddy joined him for the voyage to Mott’s Creek Inn, where they would have lunch.

“It was a warm day, and I took off my jacket that had my keys in the pocket and threw it on the seat in the stern,” said Schaffer. “Then when we stopped at the restaurant, I said, ‘Where’s my jacket?’ It must have gone overboard when I sped up. I figured it flew out in the bay and we would never see it and the keys again.
