Two men were arrested on Tuesday in connection with the murder of two construction workers in Stung Treng province.

Khun Sok, 24, and his co-worker, Chan Sorphoan, 23, were both murdered on Sunday while fishing near their construction site in Srekor commune, according to Siv Sameth, the military police’s director of criminal investigations in Stung Treng.

The two men were fishing with suspects Vin Da and Sam Chanthouen when Da allegedly killed Sok with a machete, then turned on Sorphoan, killing him when he tried to escape.

Da has refused to cooperate with authorities, beyond admitting that he had had a dispute with one of the men over a woman in the past, Sameth said.

Chanthoeun admitted he helped hide the bodies after Da killed them, but claimed Da threatened to kill him if he didn’t. Chanthoeun also gave information leading to the discovery of the bodies.

“Authorities discovered the victim’s bodies had been slashed many times and have begun to decay,” Sameth said.

“Both suspects were charged with premeditated murder and will be sent to Stung Treng Provincial Court on Thursday.”
