Author highlights untold stories from Arlington Cemetery in new book

There are hundreds of thousands of headstones at Arlington National Cemetery in Washington D.C. Every stone there tells a story. Majority of those buried are military veterans, but lying beside them are the loved ones who supported them and who have their own stories to tell. Those stories are highlighted in a new book "A Walk Among Heroes: Searching for America's Better Angels." Air force veteran and author Gary Zelinski spoke to FOX 11 about his book and what he uncovered.
