Of course, such doesn't mean that he was a Mormon, but it does make it quite possible, indeed likely. Many of the U.K. media reports gave, not surprisingly, glowing reviews of the life and service of the brave, young hero. (As here.) None, evidently, have said whether he was Mormon.
1. If this young man was a Mormon, then why isn't this part of the stories while the same U.K. press mentions regularly the religion of the man who invaded the home of the Burmese dissident? Such suggests an anti-Mormon bias, I think. (There is a slight case to be made in that Yettaw was supposedly researching a book on religion ...)
2. In all of my reading of news articles about the church, it is as true in media as it is in face-to-face life. The best public relations the church has is through people who live the gospel fully. Stories of our missionaries and of our volunteers -- and of our brave soldiers like this young man appears to be -- are almost always the most positive stories about the church. Let your light so shine remains true. Let's hope the press picks up on the Mormon angle, insofar as they pick up on it for the Burmese story.
