The Asian Human Rights Commission is calling for proper investigation into the murder of a Takeo province farmer, who was found dead in a canal near his home May 8.

No one has been arrested in the murder of Cheang Som, 56, from Ta O Khang Choeung village, who was killed following an argument with a former police official, the Commission said.

Som Horl, 25, son of the victim, said he and the surviving family were living with horror and intimidation.

The unsolved murder comes ahead of July’s national election and amid election violence, including the deaths of at least two other activists.
