In 2009, Jared Fishman was a young prosecutor working on low-level civil rights cases in the Justice Department when a file landed on his desk. That folder contained two items: a story from  The Nation  magazine looking into a mysterious death in New Orleans following Hurricane Katrina, and an autopsy report for a man named Henry Glover, whose charred remains were found in a burned-out car two weeks after the storm. The autopsy report, bafflingly, listed no cause of death.
