Australian truck driver Simon Carman, 45, could receive a substantially reduced prison sentence if he is convicted of murdering Thai teenager Tunchanok Donhomla, 17, in Pattaya and reaches a compensation agreement with her family under Thai law. Carman is being held at Pattaya Remand Prison after being charged with murder following the discovery of the teenager’s body, concealed in a suitcase left in long grass near railway tracks.

Carman, from Perth’s southern suburbs, was arrested at Bangkok’s main international airport, while police alleged he was preparing to leave Thailand on a flight to Australia. He denies murdering Tunchanok, known as Cake, and claims he acted in self-defence. Police have said their investigation remains ongoing.
According to police sources cited by the Daily Mail, discussions over financial compensation for the victim’s parents, Thongchai Donhomla and Oradee Bussarakum, are expected to form part of the legal process. The sources stressed that compensation does not prevent prosecution, but may be considered by the court alongside a guilty plea and expressions of remorse when deciding any sentence.
One police source said the family could be asked what level of compensation they would accept, with negotiations continuing until an agreement is reached. The source gave one million baht, about AU$43,000, as an example figure, noting it represents around eight years’ wages for someone earning the provincial minimum wage per day.
The same source claimed that a guilty plea could reduce a sentence by 50 per cent, while a compensation agreement accepted by the victim’s family could carry significant weight during sentencing. They suggested that, in such circumstances, a convicted offender could potentially be released after as little as seven years. Under Thai law, however, compensation alone does not guarantee a reduced sentence, with the final decision resting with the court.
Prison officials told the Daily Mail that Carman has shown no visible emotion since his arrest and has not received visits from family, friends or members of the local expatriate community. He has been transferred to the hospital wing of Pattaya Remand Prison and is being housed separately from the main prison population for safety reasons.
The Daily Mall reported that authorities said Carman can be held at Pattaya Remand Prison for up to 84 days while detectives continue gathering evidence. Police have stated that he is cooperating with the investigation.
