Police have arrested a woman who allegedly conspired with her mother and half-brother to murder her estranged South African husband in Kaeng Khoi district of Saraburi province.
Kacharin Duvel and her half-brother Surasith Panchathepmonkol have been charged with the murder of Oswald Heinrich Duvel, 50, a South African national reported to have been working in Thailand as the manager of a design company.
Police found Duvel's naked body on the roadside on Sept 30. He had been shot through the mouth. Initially, Ms Kacharin and her family denied knowing anything about the killing, police said.
Police then learned that Ms Kacharin and Duvel were fighting in court for the custody of their three-year-old child.
The victim's car was found abandoned on the roadside and investigators found evidence linking his wife and her half-brother to the murder.
They were questioned again and later confessed to the murder, police said.
Police said Ms Kacharin admitted she lured Duvel to his death, offering him the chance to see his son.
Her half-brother is the suspected shooter, police said. Ms Kacharin had allegedly planned the murder with her mother, Woraporn Panchathepmongkol, and half-brother.
The accused widow told police she was tricked into marriage so that her husband could work in Thailand.
They later split up and Duvel said he wanted custody of their child.
Ms Kacharin and Mr Surasith have been charged with premeditated murder, while her mother, Woraporn, will be a state witness, police said.
A wake for Duvel will be held tonight from 7.30pm in a marquee outside Bar 20-2 in the Queen's Park Plaza bar area on Sukhumvit Soi 22.
