SUITCASE HORROR: Beautiful Thai teen ‘Cake’ found naked and stuffed in a bag by railway tracks after night with Australian tourist – family demand he is EXECUTED as they bury their only child
She was just 17. A dutiful daughter from a quiet village in north-east Thailand who promised to bring home clothes for her baby cousin. A girl whose nickname was Cake, who looked after her great-aunts and smiled through a tough life without her mother.
Thanchanok Donhomla – known to everyone who loved her as Cake – never came home.
Instead, in the early hours of a Saturday morning in late June 2026, Thai police found her naked body bent double and stuffed inside a black suitcase discarded beside railway tracks in the seedy resort city of Pattaya.
The teenager had been strangled. Her face was bruised and swollen. Her teeth were broken. The suitcase had been left like rubbish near the tracks, a short distance from the condominium where she was last seen alive.
An Australian man, 45-year-old former truck driver Simon Peter Carman, from Ballarat in Victoria, has been charged with her murder. Police say he was arrested at Bangkok’s Suvarnabhumi Airport while allegedly trying to flee the country on a flight back to Australia. Officers noted scratch marks on his neck and arms.
Carman has been charged with murder, concealing a corpse, moving or destroying a body, and taking a minor aged between 15 and 18 for indecent purposes. He remains in custody in Pattaya and has denied the charges. Thai police say he will be held for up to 84 days while they gather evidence.
The case has horrified Thailand and sparked fury across Australia. Cake’s grieving family have made their feelings clear: they want the death penalty. They do not want compensation. They want justice.
The last hours of a girl who just wanted a holiday
Thanchanok Donhomla grew up in Kalasin province, about 480 kilometres from the bright lights and dark underbelly of Pattaya. She was an only child. Her parents divorced when she was two. She lived with her father, Thongchai Donhomla, and her stepmother, Oradee Bussarakum.
She was the kind of teenager who helped around the house, cared for elderly relatives and looked after a baby cousin. Friends and family remember a sweet, responsible girl who had somehow acquired the cheerful nickname Cake. Her father used to call her Dukdik – restless wriggler – but Cake stuck.
On 16 June she told her parents she wanted to visit a friend in Pattaya. It was meant to be a short holiday. She promised to bring back clothes for the baby.
CCTV would later show her walking hand-in-hand with Carman into a condominium block at around 3.35am on the Thursday. Security footage captured the pair passing a guard and stepping into a lift. It was the last time anyone outside that room would see her alive.
A friend reported her missing on the Friday. The same friend later went to Carman’s rented room. By then, police say, Cake was already dead.
Officers traced Carman’s movements with the suitcase using CCTV. The body was discovered around 11pm on the Friday night – naked, folded into a 26-inch black suitcase left beside the railway line, roughly ten minutes from the condo.
Autopsy results confirmed the cause of death as strangulation. There were no serious wounds to the face or head beyond the bruising and swelling consistent with a violent struggle. Police say Carman allegedly told investigators the girl came at him with a knife during an argument about money and that he had strangled her unintentionally. No knife was ever found.
‘I just want him executed’
The pain in Kalasin is raw and public.
Cake’s stepmother, Oradee Bussarakum, did not hold back. ‘I just want him executed,’ she said. ‘I even asked the police if I could hit him, if I could beat him.’
Her father, Thongchai, spoke with quiet devastation. ‘My daughter had no mother, so whenever she wanted anything, she would find a way herself, and she always helped me too,’ he said. The family want the legal process to take its course. They have made clear they are unlikely to accept any compensation that might be offered under Thai custom.
Hundreds of local people attended the ritual to give Cake a peaceful afterlife. Her body was returned to the family after the autopsy in Bangkok. The community performed traditional ceremonies. Her ashes were later interred at a local Buddhist temple.
In the photographs that have circulated, an elderly relative holds a framed portrait of the smiling teenager – the same soft-faced girl with the red lipstick and gentle expression that has become the face of this tragedy.
The Australian in the black singlet
Simon Peter Carman cut a striking figure when Thai police paraded him after his arrest. Stocky, short-haired, wearing a black sleeveless top, he was photographed being led through the airport and later through Pattaya streets by officers.
Friends and acquaintances in Australia have described a man who had become increasingly isolated over the past decade. He had worked as a truck driver. Those who knew him said he had withdrawn from many of his old social circles.
Police say he was staying in a cramped rented room in Pattaya. Photographs later released show the small space where the alleged murder is said to have taken place – a basic kitchen area, wooden doors, the ordinary setting for an extraordinary crime.
Carman remains in detention. Thai law allows suspects to be held for extended periods while investigations continue. A trial date has not yet been set. Murder in Thailand can carry the death penalty or a lengthy prison sentence of 15 to 20 years or more.
A city of sunshine and shadows
Pattaya has long lived a double life. By day it is a beach resort packed with tourists. By night it is a place of bars, go-go clubs and transactional relationships that draw men from across the world. The murder of a 17-year-old has sent a chill through the city’s sex-work community. Many young women and girls who work or socialise in the area have spoken of increased fear.
Cake was not a sex worker, her family and friends insist. She was a teenager on a short visit to see a friend. That fact has only deepened the sense of horror. She could have been any girl, anywhere – a point made repeatedly by those who knew her.
The speed of the Thai investigation has been widely noted. From the moment the friend reported her missing to the discovery of the body and the arrest at the airport, police moved with remarkable efficiency. CCTV proved decisive. The suitcase was found within hours of the missing-person report.
The lingering questions
Why did a 17-year-old from a rural province end up in a condo with a middle-aged Australian tourist in the early hours? What exactly happened inside that room? Why was her body disposed of so callously beside a railway line?
Police continue to gather evidence. Carman’s alleged account of a fight over money and a knife has been met with scepticism by investigators, who note the absence of the weapon and the nature of the injuries.
In Australia, the case has prompted difficult conversations about the behaviour of some nationals overseas. In Thailand, it has reinforced long-standing concerns about the vulnerability of young people in tourist hotspots.
For Cake’s family, the legal process is only beginning. They have buried their daughter. They have performed the rituals. Now they wait for a courtroom in Pattaya to deliver what they see as the only acceptable outcome.
Thanchanok Donhomla was 17 years old. She liked looking after her family. She promised to bring home clothes for a baby. She smiled in photographs with soft eyes and red lipstick.
She will never grow older than the girl in those pictures.
And somewhere in a Thai prison cell, the man accused of ending her life waits for the full weight of the law to fall.
