A Thai woman accused of killing her former husband, a U.S. diplomat, has been sentenced to one year in prison for violating Myanmar’s immigration laws, according to a lawyer familiar with the case. The ruling was handed down Tuesday by a court in Kamayut township, Yangon.

The woman, Pavinee Supasirivisan, was found guilty under a legal provision that applies to foreign nationals who commit crimes within Myanmar. The law carries a potential sentence ranging from six months to five years in prison. Pavinee is currently detained at Insein Prison.

Despite the sentence for immigration violations, the lawyer indicated that Pavinee may still face a murder trial in Myanmar’s legal system. The lawyer spoke on condition of anonymity, citing concerns about possible repercussions from the country’s military-backed government, which maintains strict control over the flow of information.

The case has attracted international attention due to the victim’s identity. While neither U.S. nor Myanmar authorities have officially disclosed the victim’s name, multiple Western media outlets have identified him as Daniel Paul Riva. Riva, aged 43, reportedly served as an assistant regional security officer for the U.S. State Department. An online obituary bearing his name notes that he died on the same date as the reported incident and mentions his work at several U.S. diplomatic missions.

The circumstances surrounding the alleged killing remain unclear, and Myanmar officials have not released further details. The legal process in Myanmar may continue to evolve as questions about the case persist.
