What really happened at the Guantanamo Bay detention facility on the night of June 9, 2006?

According to the US government, three detainees — all imprisoned as part of the global war on terror — hung themselves in their cells that night. But Army Staff Sergeant Joseph Hickman, who was on guard that night at Camp Delta, came to believe something very different: that the three men were murdered in a secret CIA black site at Guantanamo.

After leaving the Army, Hickman spent years looking into the deaths. His investigation has led him to write a new book, Murder at Camp Delta.
