Amnesty International has urged authorities to ensure that the family of Karen human rights activist "Billy" learn the truth of what happened to him after he was last seen in the custody of Kaeng Krachan National Park officials on April 17, 2014, saying his suspected killing should not go unpunished.

MAJOR INTERNATIONAL human rights groups slammed Thailand’s failure to provide justice to the relatives of enforced disappearance victims, four years after Karen activist Pholachi “Billy” Rakchongcharoen went missing.
