A 33-year-old man accused of killing his wife and burning her body after they celebrated his birthday together was taken for a reenactment of the crime on Wednesday.

Sirichai Rakthong is charged with the murder of Chonlada Muthuwong, 27, in Nonthaburi province and then burning her body in a rubber plantation in Prachin Buri.

During the reenactment he allegedly confessed to assaulting his wife at their house in Pak Kret district of Nonthaburi and also at two locations on Chaeng Wattana Road in Nonthaburi. The vicious assaults on Chaeng Wattana Road were caught on CCTV and the recordings have been shown on TV news.

Police said the couple celebrated his birthday together on Saturday, and the beatings began around 3am on Sunday.

The victim's burned skeleton and a burned suitcase were spotted in a rubber plantation in Sri Mahaphote district of Prachin Buri on Tuesday night.

Police said Chonlada's bracelet and gold ring were found with the burned remains. Her mobile phone signal had also been detected in the area.

According to police, Mr Sirichai said he and his wife were both drunk at his birthday party, and she made reference to his ex-girlfriend.

Police said the woman most likely died at the house after being hit on the head with a hard object.

Later on Sunday morning, Feb 18, Mr Sirichai realised his wife was dead. He stuffed the body in a suitcase which he placed in their car. He stopped at a petrol station near their home to buy petrol, which he used to burn the body in the suitcase when he reached the plantation in Prachin Buri, according to police.
