In Yala violence, Suchai Chaisith, 46, was found dead with multiple gunshot wounds to his head and torso at a house in tambon Ban Rae. Three spent 9mm casings were found at the scene.
Suchai was at a house used for durian trading when a gunman on a motorcycle opened fire on him. He was shot in the head, chest and abdomen.
Police said the victim, a resident of Songkhla's Hat Yai district, ran a durian trading business and they were investigating if the shooting was a business conflict or the work of insurgents.
