Naruthai Port was the sole survivor of the house fire which killed her husband, 72, and 17-year-old son Worraphat Sukkaew around 3am on November 30 in Ao Nang, Krabi.
Mrs Naruthai was taken to Krabi Hospital with serious burns following the blaze, and yesterday (December 1) spoke to police about the events leading up to the fire.
Mrs Naruthai told police that before the fire started, she and her husband had an argument about Worraphat, who lived with them, and how he used the internet too often. She also told police she was jealous because she thought Mr Port was cheating on her, and this made him angry.
She said that Mr Port then locked all the doors in the house before cutting the tube to a gas tank, and ignited the gas, which set the house on fire.
When the fire started she tried to open the doors, but was unable to because all the locks had been changed, presumably by Mr Port.
She cried out for help and her neighbour called police. Mrs Naruthai was rescued after police smashed the window, and she was taken to Krabi Hospital with serious burns. Police said at the time they believed the fire was started by arson, based on the state of the gas cylinder and also two motorbikes that were found nearby with the petrol tanks open, the seats up, and fuel-soaked towels inside.
Mr Port’s body will be sent for an autopsy to determine the cause of death.
The couple worked as real estate agents in Ao Nang and also ran a hotel.
