A gunman walked up behind a gambler and shot him dead during a hi-lo dice game at a funeral in Phatthalung on Wednesday night.
Two other people were wounded by exiting bullets.
The murder occurred at a house where funeral rites were being held for a 76-year-old man. Police were called to the scene about 10.30pm.
