SALT LAKE CITY (AP) _ A Navajo man who helped stump the Japanese during World War II using a code based on his native language has died in suburban Salt Lake City. Ernest Yazhe’s daughter Melissa Yazhe tells The Salt Lake Tribune that her 92-year-old father died of renal failure Tuesday. Yazhe joined the U.S. Marines when he was 19 and became one of the hundreds of code talkers who played a vital combat role by transmitting battlefield messages in an unbreakable Navajo-based radio code.
