Spalding Gray was working on a new piece when he went missing last week. “His family last saw him Jan. 9, when he walked away from his SoHo apartment without his wallet after having seen the movie “Big Fish” with his wife, Kathleen Russo, and one of his sons. There have been subsequent reports that he was seen on the Staten Island ferry later that night, and Russo has said she fears he may have tried to jump off the boat.”
