Evidence: Brad Meltzer (born April 1, 1970) is an American political thriller novelist, non-fiction writer, TV show creator, and comic book author. Using his TV show, Brad Meltzer's Lost History, he told the story of the missing flag and asked Americans for their help in returning it. Four days later, a former Marine walked into a fire station in Everett, Washington, said that he saw Meltzer's TV show, and that he now wanted to return the flag. Meltzer unveiled the flag at the National September 11 Memorial & Museum in New York, where it is now on display.
