Walter R. Reca was a paratrooper and claimed he’d been a spy. Carl Laurin published a book last year about his friend Reca. According to D.B. Cooper & Me: A Criminal, a Spy, My Best Friend, Reca admitted to Laurin that he was the missing hijacker. Reca supposedly taped a confession several years before he died, and swore Laurin to keep his secret until after his death. In those years, Laurin never considered taking the story to the FBI.
