He faces charges of murder, illegal possession of a gun and obstructing an investigation by hiding a body and denying any knowledge of it, even though subsequent DNA tests proved that the rotting contents of the bin were the remains of Ms Rungnapa.
His next hearings before the Phuket Provincial Court are scheduled for February and March next year. He has reportedly not requested bail.
Dokset was arrested on February 28 after a tip-off that Ms Rungnapa’s body was stashed in his house. She had not been seen for the best part of three years.
Dokset denies killing her, saying that she died during an argument with him, when he pushed her and her head hit a wall.
