Simon Peter Carman was arrested in June after Thai teen sex worker Tunchanok Donhomla went missing in Pattaya. Her body was found stuffed in a suitcase near railway tracks shortly afterward. At a recent court hearing, Carman faced charges including murder and concealing a corpse; he could receive the death penalty if convicted of premeditated murder. During the hearing, Carman indicated he would change his plea to guilty on the charge of hiding the victim’s body after being advised by a judge that evidence against him was strong. The victim's family, who will meet Carman for the first time in court, seeks the death penalty and has filed a civil lawsuit for $49,000 in damages.

Story summary
Tunchanok Donhomla, a 17-year-old Thai teenager known as "Cake," was found dead in June near railway tracks outside Pattaya, Thailand. Her naked body was inside a black suitcase. The teen had last been seen with Simon Peter Carman, an Australian truck driver from Perth, two days prior to the discovery.
Carman, 45, has since been arrested and charged with intentional murder, concealing a corpse, moving or destroying a corpse, and abducting a minor for indecent purposes. He could face life imprisonment or the death penalty if convicted. In court appearances, Carman initially denied all charges but later pleaded guilty to concealing the body after being advised that evidence against him was strong.
The victim's family has filed both criminal and civil cases against Carman. They are seeking $70,500 in compensation and have expressed a desire for the death penalty as they feel it would be justice for Tunchanok's life. The father of the teen stated that he felt angry upon seeing Carman deny the charges during their first face-to-face encounter in court.
