What Happened
The grieving father of a 17-year-old Thai girl found dead inside a suitcase near railway tracks has forcefully rejected self-defence claims made by the Australian man accused of her murder. Simon Peter Carman, 45, broke his silence from inside Pattaya Remand Prison to maintain that he acted in self-defence during a confrontation with Tunchanok Donhomla.
However, the teenager’s father dismissed the public statements entirely, telling 7NEWS in a direct interview, I don’t want to hear his apology. The family has expressed deep sorrow over the loss of their only child and is calling for the maximum penalty if Carman is convicted.
The Timeline
Thai police have outlined a timeline of the events, alleging that Carman met Tunchanok along Pattaya’s Beach Road in the early hours of June 25 before returning with her to his accommodation. Security footage subsequently captured Carman leaving the building alone several hours later, and later video allegedly showed him moving a large suitcase out of the premises.
Tunchanok’s body was discovered hidden inside a suitcase near railway tracks just two days after she was last seen alive. An autopsy revealed that she died from suffocation. Carman was later apprehended by authorities at Bangkok’s Suvarnabhumi International Airport on June 27 as he prepared to board a flight bound for Perth.
Who Said What
Speaking to the ABC’s Foreign Correspondent in his first media interview since his arrest, Carman claimed that an argument over money escalated rapidly when Tunchanok allegedly attempted to stab him with a knife. He stated during the interview that he tried to restrain the teenager and did not intend to kill her.
Describing the fatal encounter as an unavoidable situation, he added that he felt deeply sad about what had happened. Carman has pleaded not guilty to all charges against him, and his account represents his own version of events, which has not yet been established or tested in a court of law.
Tunchanok’s father voiced strong, unwavering opposition to Carman receiving bail and firmly rejected any expressions of remorse from the accused. “I have already lost my child,” he told 7NEWS, explaining further that Tunchanok was his only child and that his entire family had placed all of their hopes in her future.
Why This Matters
Carman currently faces four distinct charges, including murder, concealing a corpse, and an offence relating to taking a minor for indecent purposes. Under Thai legal provisions, a murder conviction carries a severe potential penalty of life imprisonment or death.
Pattaya police recently confirmed that they have officially completed their criminal investigation and are in the process of transferring the complete case file to prosecutors, where Carman’s self-defence claim will be carefully evaluated against the gathered prosecution evidence during upcoming legal proceedings. The father has explicitly called for either life imprisonment or the death penalty if Carman is ultimately convicted.
What Is Still Unclear
The exact timings are unclear, as this timeline contains some discrepancies from previous reports. While police allege the pair returned to his accommodation in the early hours of June 25, the precise moment of death remains a critical point for the defence’s self-defence argument.
Carman has maintained he did not know Tunchanok was 17, claiming he believed she was aged somewhere between 25 and 35. This discrepancy regarding her age is central to the charge of taking a minor for indecent purposes. The investigation concludes with the case moving to prosecutors, where these specific details will be scrutinised.
Background Context
Prior to her tragic death, Tunchanok, who was affectionately known by family and friends as “Cake,” lived with her father and stepmother in Kalasin. Her stepmother shared details about the teenager’s life, noting that she had assisted the family by selling fruit or floral garlands.
According to her stepmother, Tunchanok had traveled to Pattaya only after expressing a personal desire to see the sea. This trip ended tragically when her body was found stuffed inside a suitcase near railway tracks around a 10-minute drive from Carman’s accommodation in Jomtien.
Legal Proceedings
Pattaya Police Colonel Anek Srathongyoo said investigators would submit the case file to prosecutors on Monday, 17 August 2026, with prosecutors having until September 18 to decide whether to indict Carman. The accused man has been detained at Pattaya Remand Prison for almost two months following the death of Thai teenager Tunchanok Donhomla.
In his first account of what he claims happened inside his room, Carman told the ABC he had met Tunchanok while she was with two friends and said she subsequently followed him home. He claimed he gave Tunchanok 500 baht – about $21 – before she demanded more money and produced a knife.
Carman said he repeatedly asked her to put the knife down as the pair struggled, before she eventually “went limp”. The prison interview was a rare one, with the ABC reporting it was the first foreign news organisation in at least 15 years to receive permission to interview a foreign inmate inside a Thai prison.
Family Statement
The family’s grief is compounded by the loss of their only child. “I have already lost my child,” he told 7NEWS, explaining further that Tunchanok was his only child and that his entire family had placed all of their hopes in her future.
Speaking separately to the ABC, he urged the relevant authorities to impose the maximum possible sentence available if Carman is ultimately convicted, calling explicitly for either life imprisonment or the death penalty. The father has made it clear that any apology from the accused is insufficient given the magnitude of the loss suffered by the Donhomla family.
Investigation Status
Pattaya police recently confirmed that they have officially completed their criminal investigation and are in the process of transferring the complete case file to prosecutors, where Carman’s self-defence claim will be carefully evaluated against the gathered prosecution evidence during upcoming legal proceedings. The case now moves to the judicial phase where the conflicting narratives will be tested.
Conclusion
The Donhomla family stands firm in their rejection of the accused man’s narrative, while the legal system prepares to weigh the evidence presented by both sides. As prosecutors review the file, the focus remains on determining whether Carman’s claims of self-defence hold up against the physical evidence and witness testimony gathered during the investigation.
