Roeder was among 52 Americans held hostage in Iran for 444 days after their capture at the U.S. Embassy in Tehran. On the 30th anniversary of their release, at least 10 former hostages have said they will join each other for a reunion hosted by the U.S. Military Academy at West Point. (AP Photo, File)
