The man who wrote a 50-year-old message in a bottle found on Wednesday has been tracked down. ABC located Paul Gilmore, who wrote the letter when he was 13, through his family in Australia and England, who say that he’s currently on a cruise in the Baltic and he doesn’t know his letter has been found yet. But his family was pleasantly surprised by the resurfacing of his letter. “It’s amazing, absolutely incredible,” his sister Annie Crossland said, according to ABC.
