Progress in the mysterious case of a man and woman found dead. A search of their car revealed two used condom packets, cough medicine, and nerve inflammation medication. Locals describe the moment they found the bodies and suspect the deceased were not from the local area around here.
Rescue officials from the Ruamkatanyu Foundation were alerted to the discovery of a man and woman’s bodies inside a sedan registered in Bangkok, parked in Soi Bang La Waek 15. The deceased were later identified as Mr. Worapon, 45, and Ms. Patcharin, 27, as previously reported.(Mysterious deaths of man and woman found in car with used condoms; authorities investigating cause.)
On 4 July 2026, reports indicated that an initial inspection inside the car showed no signs of assault or missing belongings. It was noted the vehicle was equipped with a donut-shaped LPG gas tank at the rear. Additionally, cough medicine, two packets of used condoms, and medication for nerve inflammation belonging to Mr. Worapon were found inside.
Initial findings from Siriraj Hospital doctors estimated the victims had been dead for about 8 to 10 hours. Rescue workers then transported both bodies to Siriraj Hospital for autopsy to determine the cause of death.
Meanwhile, Mr. Jamrat Kaewkrajang, 68, a local resident, said he went to retrieve his car from a garage around 3 a.m. to take his wife to the market. He noticed the victims’ sedan parked by the fence with the engine running. He knocked on the window to ask them to move but received no response, assuming they were asleep, so he drove off. When he returned around 5 a.m., the car was still there but the engine was off, so he went back inside his home.
At about 10 a.m., he checked again and saw the car still parked in the same spot. Feeling concerned as no one answered his calls and the car was locked from the inside with sunshades covering the windshield, he called neighbors to help. They found a man unconscious inside the car and a woman unconscious beside it, frothing at the mouth. They then contacted police to investigate.
He said he did not recognize the deceased, especially the man, and believed they were not locals from this area. He estimated the car had been parked since around 11 p.m. He admitted feeling shocked by the incident, as there had never been a death like this in the alley before.
Mr. Sarawut, 22, younger brother of Ms. Patcharin, said his sister worked as a swimsuit salesperson. After finishing work late at night, she told him a friend would pick her up to attend a birthday party and left home around 2 a.m. He had never met the man who was driving but knew his sister was talking to a man. He did not want to interfere in his sister’s affairs. The car where the bodies were found was only about 30 meters from the house he rented with his family.
CCTV near the scene showed the vehicle arriving at 2:08 a.m. on 4 July 2026. Around 3 a.m., Mr. Jamrat knocked on the car window but received no response, suggesting the couple had already died. The time from parking to death was about 90 minutes. Doctors initially suspect excessive carbon dioxide inhalation but plan to analyze a Yeti cup found to see if any substances were mixed inside. Another theory is the car overheated; the hood was left slightly open to cool the engine, but the engine may have shut off due to overheating. Afterward, the couple may have become exhausted and fallen asleep, causing them to suffocate and die.
