Multiple reports say a Thailand bar owner has testified that Perth man Simon Carman disputed a bill about a week before he is alleged to have murdered 17-year-old Tunchanok Donhomla. According to the accounts, the earlier incident involved an argument at the bar over the cost of sexual services. The bar owner says Carman challenged the charge, indicating a disagreement over the amount due.

The reports also state that investigators later alleged Carman killed Donhomla after another dispute. Both outlets frame the disputed-bill episode as part of a timeline leading up to the alleged murder, but they do not provide further details about the subsequent killing beyond the existence of the earlier argument.

As reported, Carman is linked to the case through allegations in relation to Donhomla’s death. The coverage reflects the bar owner’s claims and describes the earlier dispute as relevant background to the matter under investigation, without attributing guilt beyond the allegations.
