Nguyen, a South Vietnamese general who briefly gained control of the government in a coup and went on to lead a "government in exile" in California, has died. Nguyen died Jan. 11, 2013, at a San Jose, Calif., hospital after struggling with diabetes-related health problems, said Chanh Nguyen Huu, who succeeded Nguyen as head of the Garden Grove, Calif.-based Government of Free Vietnam in Exile. He was 86. (AP Photo/Horst Faas, File)
