An outspoken radio journalist has been shot dead while hosting a singing contest in the Philippines, police said Tuesday, the latest killing in the world's most dangerous country for journalists. An unidentified gunman approached Desidario Camangyan, 52, during a village songfest in the small southern city of Mati on Monday night and killed him, according to local police. "The victim was about to sit down after emceeing (the contest) when the assassin climbed up the back of the stage and shot him at close range," said regional police spokesman Senior Superintendent Querubin Manalang. "It was dark and loud where the shooting took place, so no one really noticed." Manalang said the motive and people behind the murder remained a mystery.
