Tom and Graham work their way up the chain of command, looking for someone — anyone — who can explain how and why this incident was buried. One general claims he can't recall the incident. Another talks with the team at the Pentagon, then changes his story about Duncan Hunter's involvement.

As Tom and Graham work to track down the men in the courtyard, one of the wounded Marines has long remained elusive. His former comrades wonder if he's even still alive. Eventually, with help from Carlos, the team finds David. His chilling story reflects the lingering wounds of war.

Hoping to get their hands on the official investigation, the NPR team flies to Tucson. But problems begin shortly after arrival. The widow of a man who died in the explosion wants to know why the Marine Corps lied to her. Tom and Graham want to know why the recommended punishments were overturned. The team finally confirms a crucial detail from the original tip.

The wounded are evacuated. The battle subsides. Now the men of Echo 2/1 begin to wonder: What happened? The Marine Corps says "no records exist" but Tom and Graham find testimony before an obscure Congressional subcommittee that says otherwise. The team also finds that promises made — to Congress, to the families of the dead and to wounded Marines — have been broken. And, they hear from one man who knows exactly what happened in the courtyard of that schoolhouse — but they still have to wonder, why was this covered up?

NPR's Pentagon Correspondent, Tom Bowman, receives a shocking tip from a trusted source: A deadly explosion during the Iraq War was an accident—friendly fire, covered up by the Marine Corps—and the son of a powerful politician may have been involved. He partners with an old pal, Graham Smith, to investigate, and they discover the truth is even worse than the tipster realized. After dozens of interviews, the team patches together the story of the First Battle of Fallujah — the days and hours before the explosion — from the men who were there.

In our final episode of the season, we start researching the names on the secret list of 2,746 Cuban excludables. What we find confirms many of our suspicions about the arbitrariness of how the U.S. government created the list. Our reporting takes us — where else? — to Cuba, to finally track down the men on the roof and hear them tell their own stories. What had they hoped to find in this country and what had they found instead? Finally, our journey takes us to one last interview in a high rise in Vancouver, Canada, where we hear from the man who led the uprising at Talladega, and made the decision to take to the prison's roof to display banners made from bedsheets that read, Pray for Us and Please Media: Justice, Freedom, or Death.

Hosted by NPR's Pentagon correspondent Tom Bowman and Graham Smith of the Investigations unit, Taking Cover isn't just a show about the worst Marine-on-Marine friendly fire incident in modern history. It's a story of betrayal, brotherhood, and what's owed—to families, the wounded, and to the American public—when we send our young to war. Coming soon, after this week's conclusion of White Lies.

Since we began reporting this story, we've been after a list. A secret list. On it are the names of 2,746 people whom the US government deemed excludable, including the men on the roof. The government has kept this list so secret that at one point it went so far as to classify it. None of the Mariel detainees knew if their name was on the list or not. In fact, nobody knew what names were on the list. Until now. In Episode 7, the story of a list that sparked uprisings, separated families, and changed the trajectory of U.S. immigration policy. And the story of what we learned when we finally got our hands on it. Want to hear the next episode of White Lies a week before everyone else? Sign up for Embedded+ at plus.npr.org/embedded.

In Episode 6, we sneak into the graveyard of the Atlanta federal penitentiary with a radical peace activist to learn more about what happened in the prison in late 1984. A peaceful protest by detainees held in the Atlanta pen resulted in a violent crackdown, and one of the detainees, a man named Jose Hernandez-Mesa, was charged in federal court with inciting a riot. We tell the story of his trial — and the surprising verdict that began reshaping public opinion about the Mariel Cubans who were being detained.

On May 18, 1980, a man named Genaro Soroa-Gonzalez arrived in Key West from the port of Mariel. With no family waiting to sponsor him, he was sent by plane to a resettlement camp at an army base. There he was interviewed by the INS and, a few days later, he boarded another plane, this one bound for the federal prison in Atlanta. But wait - he'd committed no crime, so why was the US government detaining him? And how long could they hold him? In Episode 5, the story of Genaro Soroa-Gonzalez and the beginning of the indefinite detention of Mariel Cubans. Want to hear the next episode of White Lies a week before everyone else?
