MANILA — Police say a radio journalist has been fatally shot by a motorcycle-riding gunman in the northern Philippines. Cabanatuan city police chief Eli Depra said no motive was known for the killing of Julius Cauzo early Thursday. His colleague at DWJJ radio station, Elena Quijano, says he had received death threats but it was unclear why. He was the vice president of the provincial press club. The media watchdog Center for Media Freedom and Responsibility says if his death were found to be work-related, he would be the fourth journalist killed in the Philippines this year. — AP
