Marohpee Itae, 26, was found dead in front of his house in Rangae district. His body was riddled with AK47 bullets. He had been granted bail while on trial in a provincial court in connection with violence in the predominantly Muslim region.
Lt Col Suthipong Sophonsukkul, deputy commander of Rangae police, said militants in the same cell as Marohpee might have wanted to silence him so that they would not be incriminated in court.
