Pattaya, Thailand
A 46-year-old Australian man from Western Australia has been charged in Thailand with the murder of a 17-year-old Thai girl whose naked and brutally beaten body was discovered stuffed inside a suitcase dumped beside railway tracks in Pattaya. The case has rapidly gained worldwide attention due to its shocking details, the suspect’s self-defense claim, the victim’s family’s demands for execution, and new revelations by Australian media about his background, including a history as a former truck driver on workers’ compensation, his loner and “slow” personality, improper gun ownership, strange habits, and extensive online pursuit of women via the Threads platform.
According to Thai police and CCTV evidence reported across multiple outlets, Simon Peter Carman allegedly picked up 17-year-old Tunchanok Donhomla (also referred to as her Thai nickname “Cake”) from the Jomtien beach area in the early hours of June 25th, 2026. CCTV footage captured the pair walking hand-in-hand into Carman’s rented condominium on Jomtien Second Road around 3:34 a.m. Police allege both parties initially agreed to engage in sexual services.
Hours later, Carman allegedly killed the teenager during a dispute over payment. Thai police reports indicate they had agreed on 1,000 baht but an argument erupted when Carman reportedly offered only 500 baht. Carman has claimed he acted in self-defense after the girl allegedly threatened him with a knife and attempted to rob him. He told investigators she “disappeared from the room while I was asleep” in one account, which CCTV evidence clearly proves false. He claimed scratches on his body were caused by spiders in his room, not a struggle with the victim.
Carman allegedly placed the body in a suitcase, transported it on a motorcycle (visible on CCTV wheeling the suitcase out around 9:25–9:48 p.m. that day and strapping it to his bike), and dumped it in long grass beside railway tracks roughly 4 km from the condo. The body was discovered shortly after his arrest. A friend had reported Tunchanok missing earlier that day.
Carman was arrested at Bangkok’s Suvarnabhumi Airport late on June 27, 2026 (local time), minutes before boarding a Jetstar flight to Perth trying to flee the country. He faces four charges currently: Murder, concealment of a body, moving or destroying a body, and taking a minor aged 15–18 for sexual purposes. He has denied all charges and says his actions were only self defense, despite the girl being less than half his size.
In Thailand, a murder conviction can carry the death penalty (by lethal injection) or significant imprisonment. The victim’s family has publicly expressed profound grief and called for the maximum penalty. Stepmother Oradee Bussarakum told media she wants him executed, stating, “I told the police I want him executed. As a (step)mother, I don’t know what else to say.” Father Thongchai Donhomla described being “deeply saddened,” noting his daughter was helpful and had no history of drug use. The family rejected Carman’s self-defense claims.
In custody video footage, Carman addressed the family directly: “I feel bad for what happened to your daughter… It was out of my control.” He urged them to “tell other girls… just to be careful.” When questioned about scratches and bruising on his neck and arms, he attributed them to spiders as noted. Police noted the injuries were consistent with a struggle involving fingernails. His statements were universally described as bizarre and insincere.
Australian outlets, including The West Australian, news.com.au, and others, have published further details about Carman’s life in Australia, painting a picture of a former truck driver living on disability and workers’ compensation payments due to injuries.
Carman was born in Ballarat, Victoria. He grew up in Jerramungup (about 440 km southeast of Perth), with his family later moving to Albany. He lived in Perth’s southern suburbs, including Casuarina and Rockingham (including a unit in an industrial estate). He worked as a truck driver (including runs between Western Australia and regional Victoria) and as a mechanic and handyman.
He sustained significant injuries, including back and neck issues (reportedly pins/rods in his spine from a suspected motor accident in his 20s, and other trauma). These led to him living on a disability pension and workers’ compensation payments. He reportedly moved to Thailand about eight months prior seeking a cheaper lifestyle and medical treatment (Australian surgeons reportedly declined or he sought alternatives for back issues). In Thailand, he rented a modest Jomtien condominium for around A$100 per week and took on occasional handyman or odd jobs, even though he didn’t have a work permit. It is unclear what visa he was on.
Neighbors and acquaintances in Australia described him as a loner who kept to himself, socially awkward or “slow” (nicknamed “Simple Simon” by some), and sometimes aggressive or prone to outbursts, particularly when on strong pain medication. Some noted he lived messily, slept all day and was nocturnal, and had limited social interactions. Others expressed shock at the allegations, describing him as generally non-violent in their experience but agreeing be was a loner and spoke and acted very slowly.
A significant revelation involved firearms. Carman owned a collection including a .22 calibre Hornet rifle and a shotgun, which he reportedly stored improperly with ammunition in a box, breaching Western Australian gun storage laws. Associates described concern over his ownership. WA Police seized the guns around a year before he left for Thailand; his firearms licence was suspended, and he reportedly lost an appeal to reclaim it. His driver’s licence was also revoked around the same period although it is not clear why.
Australian media, particularly The West Australian, discussed Carman’s public activity on the Threads platform (Meta’s text-based app linked to Instagram). He maintained a public account you can view here and spent months using repetitive, copy-and-paste style messages to contact women worldwide, often seeming to respond to clear fake bots or AI profiles. Common openers included variations of “Hello Gorgeous, how are you doing?” or “Where are you located?” before revealing his location and attempting to move conversations off-platform.
Public replies dating back to at least January 2025 showed him commenting on posts by women sharing intimate or provocative content. Examples include replying “Too fat” to a woman asking if she was his type, responding “yes” to a post about liking Asians, and stating “I’m here, 45 !!” in another interaction. He had previously mentioned living in Rockingham and, in October (prior year), confirmed his relocation to Thailand.
This online behavior aligns with reports of him pursuing romantic or sexual interests, consistent with his relocation to Thailand and the circumstances of the alleged incident.
The case exploded across global media and social platforms within hours of Carman’s arrest and the discovery of the body. Major outlets including ABC News Australia, The Guardian, South China Morning Post, Nine.com.au, news.com.au, 7NEWS, Al Jazeera, Channel News Asia, and Reuters provided rapid coverage. Social media amplified it through videos of the arrest, CCTV descriptions, family statements, and the graphic “suitcase murder” elements.
Australian media’s deep dives into his personal history, disability pension, gun seizure, Threads activity, and neighbor accounts, added layers that fueled further sharing and discussion. Topics trending included safety for women in Pattaya, sex tourism, self-defense claims versus family calls for justice, and the contrast between his quiet expat life and the allegations. The story’s combination of international crime, a minor victim, a foreign suspect attempting to flee, and sensational disposal method drove widespread outrage and commentary on platforms like TikTok, Instagram, Reddit, X, and Facebook.
As of the latest reports, Carman remains in custody in Pattaya, Thailand as the investigation continues (with up to 84 days for completion initially although if he continues to deny the charges the case could take years). He is presumed innocent until proven guilty in a court of law. The Australian Department of Foreign Affairs and Trade has provided consular assistance. So far, he has not been granted bail and this is extremely unlikely.
