A former NYPD police officer who participated in the rescue operations after 9/11 has recently made a startling statement. Frank Marra says she saw a ghost while searching for survivors among the ruins of the World Trade Center. He described it as the ghost of an African American woman, who was dressed in white as a Red Cross worker from Second World War. The cop said the spirit looked as if it was trying to help with the rescue. Sgt. Frank Marra was not the only one who saw the specter, who a psychic medium has explained could have been a spirit, ‘soul collector’, guiding people to the afterlife.
