TAIPEI (Taiwan News) -- Police responded to a call at 6 p.m. Tuesday evening about a couple sitting motionless in a parked car on Yuantong road in New Taipei City's Zhonghe District.
After breaking the windows to open the locked BMW, the officers discovered that the two, a 49-year-old man surnamed Song and a 49-year-old woman surnamed Chen, were dead, reported China Times.
Police say that the man's lower body was nude and the woman's face was lying on his lap, indicating she may have been performing oral sex on him.
Thus far, police have seen no signs of foul play or suicide, but will investigate further to determine the actual cause of death.
As the car had been idling for an extended period of time, police believe the couple either died of hypoxia, due to poor air circulation, or carbon monoxide poisoning caused by exhaust entering and accumulating inside the tightly sealed vehicle.
The eldest sister of the woman, whose family surname is Chen, said that her younger sister had left the home at 8 p.m. on Monday night, but the next morning she received notice from her employer that she had not arrived at work. She then headed straight to the New Taipei City Banqiao District police station to help locate her sister.
Last week in Chiayi Country on April 26, two men were found dead inside a parked car that had been idling for up to five hours, and are believed to have died as a result of carbon monoxide poisoning. One of the men was found holding his phone with the last message he had sent to his friend on the social media app Line, which read that he felt "hot and uncomfortable."
