Lottery officials in the communist country of Laos are rigging the system, with drawing results often showing numbers that vanish from purchased tickets or that are considered unlucky, sources tell RFA. In one case, the winning number 134 appeared only as 5 on tickets sold throughout the day of an Oct. 14 drawing, and was later changed to 662.

The winning ticket was sold at a Plaid Pantry convenience store in Portland, and the winner is reportedly an Iu Mien immigrant, an ethnic group that came to the U.S. through a refugee rescue program and helped American forces in Vietnam during the war. He or she will receive a lump sum payment of about $422 million after federal and state taxes are taken out. Under Oregon law, with a few exceptions, lottery winners cannot remain anonymous.

The winner’s name will not be released until he or she goes through the lottery’s scheduling and security process, and the prize money is distributed. The news of the win was welcomed in the city’s large Iu Mien community, which includes a Buddhist temple, a church, social organizations and businesses. It also comes as a relief to many Iu Mien immigrants, who are struggling financially in the wake of years of low wages and high unemployment in their home country. The Oregon winner will not be allowed to keep his or her identity secret unless the person signs a document authorizing it.
