Witnesses observed the disappearance of numerous workers at Kampong Chhnang Airport Construction Site.1719 They noted a correlation between the daily criticism/self-criticism meetings and the disappearances.1720 During those meetings workers were criticised for being sick or lazy, for work mistakes, for minor offences such as stealing tobacco or for having alleged connections with the Vietnamese.1721 Several witnesses saw trucks transporting workers outside of the airport who never came back.1722 Many witnesses said they could not be sure about the real fate of the disappeared persons as they did not see the execution.1723 394.
