TOKYO (AP) - The Kyodo News agency says Japanese prosecutors have charged a U.S. sailor in the stabbing death of a taxi driver near Tokyo. Olatunbosun Ugbogu is a 22-year-old Nigerian citizen serving in the Navy. The sailor is accused of killing the taxi driver near the U.S. naval base in Yokosuka, south of Tokyo, on March 19. The Navy handed Ugbogu over to Japanese authorities earlier this month. The news agency reported the indictment on Thursday.
