A New Orleans man has filed suit against the city and the state of Louisiana for abandoning his 91-year-old mother after Hurricane Katrina. The woman, Ethel Mayo Freeman, died outside the Convention Center on Sept. 1 after she failed to receive needed medical care. She died sitting in her wheelchair. Images of her were broadcast around the world as her corpse remained outside the Convention Center. Her son, Herbert Freeman, says he watched over his mother’s body for two days. But help never came. He is suing the city and state for wrongful death. Her story is featured in Spike Lee’s new documentary on Katrina which premieres tonight.
