US diplomat Daniel Riva was found dead in Myanmar in May 2026 in what authorities are treating as a suspected murder case involving his Thai ex-wife. The case has drawn international attention due to the victim’s diplomatic role and the sensitive security environment in which the investigation is taking place. Officials confirmed he was discovered at the Sakura Residence & Hotel in Yangon, a location often used by expatriates and foreign staff.

Riva, aged 43, was found with fatal stab wounds to the head and neck. The site is located close to the US Embassy in Yangon, Myanmar’s largest city. Authorities have not released a full forensic report and independent verification has been limited due to restricted media access in the country.
The suspect is Pavinee Supasirivisan, a Thai national and former spouse of Riva. She who previously worked as a pastry chef and reportedly studied at a culinary school in Bangkok. She was initially detained on immigration-related matters before being formally charged with murder. Under Myanmar law, the charge could carry penalties ranging from long-term imprisonment to the death penalty.
Court reports indicate she has appeared in Yangon court for preliminary hearings focused on immigration violations, while the murder charge is being handled separately. Officials have not confirmed whether she has entered a plea.
Riva served as a US Diplomatic Security Service officer, working on the protection of US diplomatic missions and investigations into transnational crime, including passport and visa fraud, human trafficking, organised crime and terrorism-related activity. He had previously been posted in Suriname and Timor-Leste, where colleagues described him as a committed officer with strong engagement in international security cooperation.
The investigation is being conducted under Myanmar’s military-run judicial system, where court transparency is limited and journalists are often barred from proceedings. The US State Department has acknowledged Riva’s death but has declined to release further details, citing family privacy. Legal experts note that proceedings are expected to be slow, with immigration and homicide cases progressing separately.
Observers have highlighted concerns over due process and safety for foreign diplomatic personnel operating in Myanmar, given the country’s unstable post-coup environment and restricted judicial oversight. Authorities have not provided a confirmed timeline for a full murder trial and the case remains under active investigation.
