BANGKOK, Thailand - Two Lao-American men were shot to death Wednesday at a bus station in northeastern Thailand after returning from a trip to Laos, and Thai police suspect a political connection to the killings, a Thai television station reported.

The two men from Oregon, who claimed to be related to one of the now-defunct Lao royal families, used the names Thao Somvang and Thao Soukanh, the iTV television network said. It cited Karuna Chokpreecha, the former's wife, who witnessed the killings in Ubon Rachathani, 300 miles northeast of Bangkok.

“Thao” is a Laotian honorific roughly meaning “prince.”

The pair were shot by a man wearing a black hat as they waited to pick up their luggage after arriving by bus with four companions from the southern Lao province of Champassak, iTV reported. The men had arrived in Thailand on Oct. 17 and were scheduled to catch a flight back to the United States today.

The TV station showed a picture of an Oregon driver's license belonging to one of the victims, identifying him as Soukanh Visathep of Johnson City, born in 1942. The second dead man was not clearly identified in the report.

In Oregon, a woman who identified herself as Bounpaanh Manirajd answered a phone listed to Soukanh Visathep Wednesday night.

She said the two had been living together for nearly a decade, following her divorce and the death of Visathep's wife.

She said Visathep's daughter, Pamela, and her husband - whose last name Manirajd said she could not spell - were in Thailand and hoped to contact authorities to find out what happened.

She said the family hoped to bring the body back to Oregon.

Manirajd said Visathep had been traveling with his brother-in-law, Somveng Keonivong, but she did not know if he was the other victim in the shooting.

According to iTV, police suspected the men were killed because of possible links to a group opposed to the government of Laos, a single-party communist state.

Police with knowledge of the case could not be reached late Wednesday by The Associated Press.

The case appeared strikingly similar to one in January in which a Lao-American couple were shot dead in Nong Khai, another northeastern Thai town near the border with Laos.

Anouwong and Oulayvanh Sethathirath also had claimed to be descendants of a Laotian royal family, and apparently had contacts with some Laotian anti-government groups. They were known in their hometown of Fairview, N.C., as Phillip and Ashley McRowan.

In May, Thai police arrested Athit Klinchana, a suspected Thai hit man, who told them he was hired by the Lao government to assassinate its opponents, including the McRowans. He allegedly said he was paid $2,600 for each assassination.

During interrogation, police said they found he was linked to at least seven other killings.

The Lao government denied involvement. The status of the case is not known.

Somvang's wife was quoted saying by iTV.
