Accused Aussie killer’s wrathful encounter with a woman after a motorbike accident weeks before he allegedly strangled Thai teen: ‘King Kong’

The chilling backdrop to one of the most horrific international crime stories has taken an alarming turn, as a local woman has exposed a volatile, rage-filled confrontation she had with accused Australian killer Simon Peter Carman just three weeks before his arrest. Carman, a 46-year-old from Ballarat, Victoria, was intercepted at Bangkok’s Suvarnabhumi International Airport as he aggressively attempted to board a Jetstar flight to Perth. His arrest followed the gruesome discovery of the body of 17-year-old Tunchanok “Cake” Donhomla, who weighed a fragile 40 kilograms and was found strangled, naked, and stuffed inside a black suitcase dumped along a Pattaya railway line. As Thai authorities piece together the final hours of the young victim, an encounter from Carman’s recent past has surfaced, painting a deeply disturbing portrait of a man allegedly prone to explosive outbursts and physically intimidating behavior.

The baseline of this newly revealed pre-crime behavior is anchored in the firsthand account of Khanittha Thongsuknmag, a local Thai woman who cross-examined Carman following a routine traffic accident in the coastal resort city. According to Thongsuknmag, the interaction unfolded roughly three weeks prior to the murder, after Carman was involved in a minor motorbike collision. Rather than resolving the logistical incident through standard, calm civic procedures or insurance exchanges, the Australian national allegedly erupted into an unbridled, aggressive display of temper that left witnesses at the scene deeply shaken. The local woman recounted that Carman’s towering physical presence and hostile posturing were so overwhelming and aggressive that she internally likened his furious demeanour to that of an enraged “King Kong”—a characterization that has now taken on a deeply sinister resonance in light of the brutal physical violence later inflicted upon a defenseless teenager.

This pattern of volatile, escalatory behavior aligns with the horrifying chronological timeline constructed by Pattaya City Police investigators regarding the night of the murder. Law enforcement officials allege that Carman picked up the 17-year-old near the Jomtien Beach area of Pattaya in the early hours of a Thursday morning. Closed-circuit television (CCTV) security footage captured the pair walking hand-in-hand as they entered the elevator of a residential condominium complex. According to Pattaya Police Superintendent Colonel Anek Srathongyoo, a violent and highly charged domestic argument broke out between the two inside the apartment, reportedly centered around a dispute over financial compensation. The disagreement quickly transformed into a fatal, one-sided physical struggle, with police alleging that Carman used his significant physical advantage to choke the teenager until she was completely motionless.

In a sequence of events that investigators described as cold and calculated, Carman allegedly hidden the victim’s body inside a bathroom for roughly twenty-four hours while desperately trying to formulate a crude logistical cover-up. CCTV cameras eventually captured the Australian national leaving the residential building entirely alone on Thursday night, laboring under the weight of a large, dark-coloured suitcase. The footage subsequently tracked him loading the heavy luggage onto the back of a motorcycle and navigating the streets toward a deserted, grassy corridor adjacent to a local railway track, roughly four kilometers away from the condominium. It was there that he dumped the suitcase containing the naked body of the high schooler before racing toward the capital in a frantic, failed bid to escape international justice and return to Western Australia.

Faced with a formidable array of physical and digital evidence—including distinct, visible scratch marks covering his neck and arms that strongly indicate a desperate struggle for survival by the victim—Carman has issued a complex legal defense while under intense interrogation. While initially denying any direct involvement in the teenager’s disappearance, the suspect later altered his narrative, claiming to investigators that the death was a catastrophic accident born out of self-defense. In video clips of his police interrogation leaked to Thai media, Carman claimed that the 17-year-old “got crazy” and allegedly threatened his face with a kitchen knife while he was opening his wallet to hand her 500 baht (approximately $15). “I was holding her down because she got crazy… It was out of my control,” Carman asserted to investigators, before offering a hollow message of regret to the victim’s grieving family.

However, Thai prosecutors and the victim’s devastated family are flatly rejecting any narrative of mitigation or self-defense, pointing toward the sheer disparity in physical size and the calculated steps taken to conceal the crime. The victim’s father, Thongchai Donhomla, expressed absolute heartbreak over the loss of his daughter, noting that she had grown up without a mother and worked tirelessly to support their modest household. The teenager’s stepmother, Oradee Bussarakum, has publicly implored Thai judicial authorities to pursue the absolute maximum penalty under local law, which for premeditated murder and the exploitation of a minor carries the death penalty. As the Department of Foreign Affairs and Trade (DFAT) continues to provide standard consular assistance to the detained Victorian man, the case is moving rapidly through the Pattaya Provincial Court, leaving a community horrified by the realization that the “King Kong” rage witnessed on a local roadway was merely a prelude to an unimaginable act of violence.
