Sourigna Vongsa's eldest son, Vongsa, was executed due to his involvement in a political conflict during the Laotian Civil War. The conflict was primarily between the Royal Lao Government and the communist Pathet Lao, which was supported by North Vietnam. Vongsa was accused of being a key figure in the anti-communist resistance, and his execution was part of a broader campaign by the communist regime to eliminate opposition and consolidate power after the fall of the Royal Lao Government in 1975.

The political climate in Laos at the time was extremely volatile, with many individuals facing persecution for their political beliefs or affiliations. Vongsa's execution was emblematic of the harsh measures taken by the new government against former officials and their families, as they sought to establish control and suppress dissent.
