AUSTRALIAN TOURIST ACCUSED OF MURDERING GIRL, 17, FOUND IN SUITCASE CLAIMS HE ACTED IN SELF-DEFENCE

An Australian man accused of killing a 17-year-old Thai girl and concealing her body inside a suitcase has appeared in court in Thailand and pleaded not guilty to the charges.

Simon Peter Carman, 45, told the Pattaya Provincial Court that he acted in self-defence, claiming the teenager threatened him with a knife during a confrontation inside his condominium.

Carman is facing charges including premeditated murder, concealment of a body and offences involving a minor.

The case has attracted widespread attention after the teenager’s body was discovered inside a suitcase near railway tracks in Pattaya in June.

THE NIGHT THE TEENAGER DISAPPEARED

The victim was Tunchanok Donhomla, 17, from Thailand.

Police said CCTV footage captured Tunchanok entering a condominium in Pattaya with Carman during the early hours of June 25.

The footage reportedly showed the pair walking together and entering an elevator at around 3:34 a.m.

Later that evening, CCTV allegedly captured Carman leaving the building alone while carrying a large suitcase.

Investigators said he placed the suitcase on a motorcycle and travelled toward an area near railway tracks.

Two days later, Tunchanok’s body was discovered inside the suitcase.

CARMAN WAS ARRESTED AT THE AIRPORT

Carman was arrested at Bangkok’s Suvarnabhumi International Airport on June 27 as he was reportedly preparing to leave Thailand on a flight to Australia.

Police had been investigating Tunchanok’s disappearance and were tracking her last known movements.

Investigators later connected Carman to the case through CCTV footage and forensic evidence.

Police said DNA evidence recovered during the investigation matched Carman’s DNA.

An autopsy reported that Tunchanok suffered a brain injury and died from suffocation, according to ABC Australia.

“I ACTED IN SELF-DEFENCE”

Carman has consistently disputed the prosecution’s version of events.

During an interview from prison in August, he said he did not intend to kill Tunchanok and claimed she threatened him with a knife during an argument over money.

He said he had attempted to restrain her because he feared she would stab him.

Carman also claimed he did not know that Tunchanok was under 18.

At his latest court appearance, he again denied the charges and maintained that he had acted in self-defence.

These claims are allegations made by the accused and have not been established by the court.

POLICE QUESTIONED HIS INJURIES

Following Carman’s arrest, investigators reportedly noticed parallel marks on his neck and arm.

Police suspected the injuries could have been sustained during a struggle.

Carman offered a different explanation, saying the scratches had been caused by a spider, according to The Sun’s account of the case.

The circumstances surrounding those injuries remain part of the evidence being considered in the case.

THE SUITCASE BECAME A KEY PIECE OF EVIDENCE

CCTV footage is expected to play an important role in the prosecution’s case.

Police said cameras captured Carman leaving the condominium with the large suitcase and later transporting it on a motorcycle.

The suitcase was subsequently found near railway tracks in the Pattaya area with Tunchanok’s body inside.

Investigators have used the footage to reconstruct the movements of both Carman and the suitcase following the teenager’s disappearance.

FAMILY CALLS FOR JUSTICE

Tunchanok’s family has spoken publicly about the devastating loss.

Her father, Thongchai Donhomla, told ABC that he wanted the harshest punishment available if Carman is convicted.

The family has rejected Carman’s account of the incident and continues to seek justice for the teenager.

However, Carman remains legally presumed innocent unless and until a court finds him guilty.

BAIL DENIED

At his September 18 court appearance, Carman requested bail.

Prosecutors opposed the request, citing concerns about the possibility that he could flee Thailand.

The court denied bail, and Carman remains detained at Pattaya Remand Prison.

The Pattaya Provincial Court has scheduled a further hearing for October 12, 2026, when evidence in the case is expected to be examined.

If Carman is ultimately convicted of premeditated murder, he could face the death penalty under Thai law.

THE CASE NOW MOVES TO THE NEXT STAGE

For investigators, the CCTV footage, forensic evidence and the circumstances surrounding the suitcase remain central to the prosecution.

For Carman, the defence rests on his claim that Tunchanok threatened him and that he acted to protect himself.

Those competing accounts will now be tested through the Thai court process.

For the family of 17-year-old Tunchanok Donhomla, the proceedings represent another step in a case that began with a teenager disappearing in Pattaya and ended with the discovery of her body inside a suitcase.

The next major development is expected when the case returns to court on October 12.
