As of Monday, June 29, 2026:
The investigation into the tragic death of 17-year-old Tunchanok Donhomla continues to unfold as international authorities and the Thai legal system address the case involving Australian national Simon Peter Carman, 46.
- Formal Charges: Carman has been officially charged with multiple counts, including murder, the concealment of a body, moving or destroying a body, and the abduction of a minor for indecent purposes.
- The Arrest: Carman was apprehended at Suvarnabhumi International Airport on Friday, June 26, 2026, while allegedly attempting to board a flight to Perth, Australia.
- The Evidence: Police have utilized CCTV footage that reportedly shows Carman entering a condominium with the victim in the early hours of Thursday, June 25. Subsequent footage shows him departing alone with a large suitcase, which was later discovered by authorities near a railway line in Pattaya containing the victim’s body.
- Suspect’s Statement: While in custody, Carman has denied the charge of murder. He has claimed the incident was “out of his control” and alleged self-defence, stating that a dispute over 500 Thai Baht led to a struggle during which the teenager allegedly threatened him with a knife.
- Family’s Plea: The victim’s family, including her father Thongchai Donhomla, has spoken out regarding their profound grief. Her stepmother has publicly requested the maximum possible penalty under Thai law, which can include the death penalty.
