A customer finds a pregnant Bangkok teacher dead behind the wheel of her Mazda after ten silent hours. Police seize a charcoal brazier and a farewell letter accusing her boyfriend, already named in an assault complaint, of rejecting their unborn child.
A pregnant Bangkok primary school teacher was found dead inside her Mazda on Sunday, three days after accusing her boyfriend of assault. Waritthaporn, 25, had apparently lain undiscovered for ten hours outside a Bang Kapi convenience store. Police found burnt charcoal inside a brazier and a farewell letter thanking her struggling parents. However, it also accused her boyfriend, a prospective second lieutenant, of rejecting their unborn child after a two-year relationship. Hua Mak police suspect carbon monoxide poisoning but are awaiting an autopsy. Meanwhile, investigators must unravel the bitter paternity dispute, her final movements and the unresolved August 27 assault complaint.

A pregnant Bangkok teacher was found dead inside her car on Sunday after a bitter paternity dispute. Police found a charcoal brazier behind the driver and a farewell letter addressed to her parents. The 25-year-old also accused her boyfriend of refusing to accept their unborn child.
The red Mazda 2 stood outside a convenience store on Soi Ramkhamhaeng 60. The location is in Hua Mak subdistrict, Bang Kapi district. A customer noticed the young driver slumped motionless behind the wheel. After watching the vehicle for some time, the customer raised the alarm.
In response, Hua Mak Police Station sent investigators to the scene on August 30. Police Lieutenant Colonel Banyong Daengruang, an investigative officer, answered the call. Police Colonel Prasopchok, the station superintendent, led the operation. Forensic officers and a medical examiner from the Police General Hospital joined them.

At the same time, Ruam Katanyu Foundation volunteers sealed off the area. Investigators then opened the Mazda and found the teacher in the driver’s seat. She had shown no response before officers entered the vehicle. Police estimated that she had been dead for approximately ten hours.
The dead woman was identified as Waritthaporn, 25, from Samut Prakan province. Initial reports withheld her surname. She taught primary school pupils in Bangkok’s Bang Khen area. Notably, she was pregnant when she died.
Inside the rear of the Mazda, police found a small charcoal brazier. Burnt-out charcoal remained inside the container. Investigators suspected toxic fumes had filled the enclosed car. Pending an autopsy, police believed carbon monoxide poisoning caused her death.
However, the vehicle contained more than the suspected means of death. Officers also discovered a farewell letter written by Waritthaporn. It thanked her parents for raising her despite severe financial hardship. Their sacrifices had paid for her education and helped her become a teacher.

In particular, Waritthaporn credited her parents with giving her a future. They had struggled with poverty but continued supporting her studies. She ultimately qualified as a teacher and began working with young children. Her final message acknowledged everything they had done for her.
The letter then turned to her boyfriend and their two-year relationship. Waritthaporn wrote that she loved him deeply. Later, she became pregnant and started taking careful precautions for the unborn child. Her boyfriend then refused to accept that he was the father.
Consequently, the paternity dispute became central to the initial police inquiry. Waritthaporn’s letter described resentment and despair over his refusal. It also connected that rejection with her final decision. Police identified the boyfriend only as a prospective second lieutenant.
For now, his full name and age remain undisclosed. Police also gave no details about his military status, training or organisation. Furthermore, his account of the relationship was absent from the released information. No paternity test result was mentioned.

Separately, Waritthaporn had reported another serious dispute only three days before her death. She entered Hua Mak Police Station during the evening of Thursday, August 27. There, she accused her boyfriend of physically assaulting her. The reported attack took place at their apartment.
According to her complaint, the assault left her injured. Police did not describe the injuries or release photographs of them. Nor did they disclose what triggered the reported violence. Even so, the complaint placed the couple’s relationship before police days before her death.
On another front, investigators have not revealed whether they questioned the boyfriend after that complaint. No arrest or criminal charge was announced in the supplied information. Police also did not say whether Waritthaporn returned to their apartment. Three days later, a stranger found her dead inside the Mazda.
The timeline now forms a critical part of the investigation. Waritthaporn reported the apartment assault on Thursday evening. By Sunday, she had been dead for an estimated ten hours. Meanwhile, the farewell letter placed the pregnancy dispute at the centre of her despair.

Against that background, Police Lieutenant Colonel Banyong outlined the initial assessment. Investigators believed the death followed the boyfriend’s refusal to accept paternity. That position came from the letter and evidence inside the car. Nevertheless, forensic doctors must still confirm precisely how Waritthaporn died.
At the scene, officers carefully documented every item inside the Mazda. They photographed the brazier and examined the burnt charcoal. Additionally, they secured the farewell letter for the case file. Other contents of the vehicle were also checked for evidence.
As part of this, forensic officers examined the driver’s area and rear compartment. They reported no other person inside the car. No public information indicated a struggle within the Mazda. The vehicle remained parked directly outside the convenience store.
In parallel, police began reconstructing Waritthaporn’s final movements. They did not disclose when she drove into Soi Ramkhamhaeng 60. Likewise, no security camera footage was described in the initial reports. The reason she selected that location also remained unknown.

Crucially, the customer’s vigilance led to the discovery. The Mazda’s driver had remained slumped over for an unusually long time. The customer eventually realised that something was seriously wrong. Police and rescue workers were then called to the store.
By that stage, Waritthaporn had apparently been dead for many hours. Investigators placed the interval at around ten hours. However, only the autopsy can provide a firmer medical estimate. The examination will also check for suspected carbon monoxide poisoning.
Afterwards, Ruam Katanyu Foundation volunteers removed her body from the driver’s seat. They transported it to the Police General Hospital in Bangkok. Forensic doctors will conduct a full post-mortem examination. The results will enter the continuing Hua Mak police investigation.
Beyond the autopsy, officers must examine the August 27 assault complaint. That report predates Waritthaporn’s death by only three days. It also names the boyfriend referenced in her farewell letter. Yet no findings concerning that accusation were announced on Sunday.
At present, the assault accusation remains under examination. The boyfriend’s response to it has not been published. Similarly, his position on Waritthaporn’s written account remains unknown. Police have released no evidence supporting or disproving paternity.
Autopsy and assault inquiry remain crucial after three grim clues emerge from the teacher’s death
In the meantime, officers contacted Waritthaporn’s relatives and confirmed her identity. Her family learned that forensic doctors would examine the body. Once the legal procedures are finished, relatives can collect her remains. They will then hold religious rites.
Most significantly, police recovered three major elements from the unfolding case. The first was the charcoal brazier inside the Mazda. The second was Waritthaporn’s farewell letter. The third was her police complaint about the reported apartment assault.
Taken together, those facts created a grim three-day sequence. A pregnant teacher reported being attacked by her boyfriend on Thursday. On Sunday, she was found dead with a letter describing his paternity rejection. Burnt charcoal lay inside a brazier behind her.

Even so, the autopsy will determine the official cause of death. Investigators must also establish the timing of her final journey. They will review the car, letter and earlier complaint. Any further action will depend upon the evidence collected.
Ultimately, police are treating the case as suspected suicide through carbon monoxide poisoning. That remains an initial assessment rather than a completed forensic finding. The assault complaint also remains unresolved. Hua Mak police are continuing inquiries while awaiting the autopsy report.
