“TELL THE OTHER GIRLS TO BE CAREFUL.”

Those were the exact, bone-chilling words that just came out of the mouth of 46-year-old Australian suspect Simon Peter Carman as Thai police escorted him in handcuffs. He’s accused of stripping a 17-year-old girl naked, stuffing her into a travel suitcase, and dumping her by the Pattaya railway tracks—yet before the media cameras, he chose to play the role of a concerned protector.

True crime forums and women’s safety groups on X and TikTok are absolutely exploding with fury over this video footage, and criminal psychologists are weighing in on the terrifying manipulation tactic happening right before our eyes. Is this a classic textbook case of criminal gaslighting, or is there an even darker, hidden message meant for someone else entirely? The internet has just decoded the psychological profile of the Pattaya predator, and it is disturbing.

See the shocking media footage and find out why experts say his “advice” is a major warning sign.

In the immediate aftermath of a brutal crime, the public expects to see a suspect display panic, shame, or absolute silence under the glare of media cameras. But as 46-year-old Australian national Simon Peter Carman was paraded by police through a gauntlet of reporters following his arrest for the murder of 17-year-old Thunchanok “Cake” Donhomla, he delivered a line that has triggered a mᴀssive wave of internet fury and sparked a deep dive into criminal psychology across X, Reddit, and TikTok.

Staring directly into a flashing wall of lenses, the Perth native—accused of stuffing the naked body of a teenager into a black suitcase and dumping it along a remote Pattaya railway line—issued a calm, unsolicited warning:

“I feel very bad… Please tell other girls just to be careful.”

The footage of the exchange went viral within minutes of its broadcast. Rather than eliciting sympathy or framing the incident as an tragic accident, Carman’s remarks have been met with intense international outrage. Women’s rights advocacy groups, legal commentators, and online true crime communities are actively deconstructing the statement, labeling it a textbook display of “victim-blaming gaslighting”—a psychological defense mechanism used by high-level predators to deflect guilt and manipulate public perception even after being caught red-handed.

TikTok creators specializing in body language analysis have seized on the raw, unedited footage of Carman’s walk perp-walk. Viewers pointed out his lack of physical deflection—he did not hang his head or avoid eye contact. Instead, he locked eyes with reporters to deliver his message.

Commentators online have noted that this behavior aligns perfectly with clinical definitions of antisocial personality traits, where the perpetrator genuinely believes they can charm or manipulate their way out of a catastrophic forensic reality.

The 500-Baht Provocation Theory

What has amplified the online fury is how Carman’s “advice” intersects with his official defense strategy leaked from the Pattaya interrogation rooms. Reports indicate that Carman claimed the victim “went crazy” and threatened him with a kitchen knife following a bitter disagreement over a 500 Baht (roughly $20 USD) nightlife transaction, forcing him to act in self-defense.

On Reddit’s r/Pattaya and r/Thailand, communities of expatriates and locals are calling out the sheer hypocrisy of this defense. “He wants the world to believe he’s a victim of a wild local teenager, and that his warning to other girls is about safety,” wrote one forum moderator. “But the physical evidence tells an entirely different story. You don’t accidentally kill someone in self-defense, strip them entirely naked, fold them into a piece of luggage, and take a leisurely swim afterwards. His words are an insult to the victim’s family.”

True crime sleuths argue that the “she had a knife” narrative combined with his “be careful” statement is a coordinated effort to frame the deceased 17-year-old as the aggressor. Because the victim is ᴅᴇᴀᴅ and cannot defend her reputation, Carman is utilizing his media access to establish a narrative that paints young local women in Pattaya’s entertainment zones as volatile risks, thereby justifying his alleged use of lethal force.

“He’s trying to tell the world she didn’t play by the rules, so what happened was inevitable,” a TikTok commentator observed in a viral video analyzing the case. “It’s the oldest, ugliest trick in the book.”

Lashing Out on X: International Outrage

The global response on X has been unyielding, with many comparing Carman’s demeanor to notorious historical cases where killers adopted a helpful or paternalistic tone with the press or police before their full crimes were unmasked. Citing his background as a middle-aged foreign national targeting an impoverished underage girl from Kalasin, users have transformed the quote into a rallying cry against the broader culture of predatory tourism in Southeast Asia.

“When an older man with a history of domestic issues in Australia kills a vulnerable teenager and then tells other teenagers to ‘be careful,’ it sends a chill down your spine,” wrote an Australian human rights activist on X. “It reads like a threat. It reads as if he’s saying: Look what I did to her because she stepped out of line. The rest of you are next if you aren’t careful.“

This darker interpretation has fueled theories on Discord true crime servers that Carman’s message wasn’t aimed at the general public at all, but was a specific, intimidating message directed at other young women in his immediate Jomtien neighborhood who may have known about his private life or past visitors to room 402.

The Forensic Fight Ahead

While Simon Carman continues to test his manipulative messaging in front of the press, Thai prosecutors are preparing a dossier that relies strictly on cold, hard forensics rather than narrative spin.

Medical examiners are currently focusing on the defensive wounds found on Carman’s arms and neck. The presence of deep, vertical fingernail scratches heavily refutes his claims of a clean, immediate self-defense struggle against a knife, pointing instead to a prolonged, agonizing struggle where the victim fought desperately for air while being strangled.

Ultimately, Carman’s brief stint as a media advisor is likely to backfire. Legal experts commenting on Thai court proceedings note that judges in Chonburi province view a lack of genuine remorse and attempts to blame the deceased as aggravating factors. Instead of securing him a lighter sentence, his chilling words before the cameras may be the very thing that cements his path toward Thailand’s maximum criminal penalties.
