Thailand. A 46-year-old Australian national from Western Australia, Simon Peter Carman, has been formally remanded to Pattaya Prison after being intercepted by immigration authorities at Bangkok's Suvarnabhumi Airport.

Carman was apprehended while attempting to board a flight to Perth following the discovery of the naked body of 17-year-old Tunchanok "Cake" Donhomla.

Her body, bearing severe signs of facial trauma and suspected strangulation, was found stuffed inside a black suitcase abandoned alongside Pattaya's railway tracks.

While initially telling authorities the teen simply vanished while he slept, subsequent interrogation reports from local media outlets like Thairath indicate Carman has shifted his stance.

He now claims he acted in self-defense during an escalation over service pricing. He alleges he panicked after she suffered fatal injuries, keeping the suitcase in his bathroom for a day before disposal.

Pattaya City Police mapped clear surveillance footage showing the pair entering a condominium complex hand-in-hand at 3:30 AM.

Fifteen hours later, Carman is captured on camera dragging the heavy black suitcase out alone, strapping it to a motorcycle, and disappearing near the railway tracks for 9 minutes before returning empty-handed.

When confronted by investigators regarding deep fingernail scratches covering his neck and arms, Carman dismissed the physical marks to Pattaya police, claiming on video that they were caused by a spider.

In a chilling twist, Thai police told reporters that they are actively reviewing two unsolved cold cases from the past two years in the Pattaya region. Both involved female victims stuffed into matching luggage and dumped. Forensic units will cross-examine evidence to determine if a broader pattern exists.

Background checks from ABC News Australia show Carman grew up in Western Australia. His firearms license was suspended and his weapons were seized by Australian police in 2023 following local court interventions before he moved to Thailand 8 months ago.

The victim's grieving father, Thongchai Donhomla, expressed profound heartbreak, stating that his daughter was an only child who worked tirelessly to support the family.

The family has publicly demanded the maximum punishment. Under Thai criminal law, the combination of premeditated murder, body concealment, and offenses involving a minor carries a maximum penalty of death.

Australian Simon Peter Carman lived his normal life, going out, washing his clothes and talking to neighbours after allegedly murdering a teenage girl and stuffing her body inside a suitcase in Thailand, police say.

Carman remains in high-security detention without bail as forensic teams finalize the autopsy report.
