A woman in her 40s who murdered her two-day-old baby out of fear that her pregnancy from an extramarital affair would be exposed has been brought to trial 10 years after the crime.

The Tongyeong Branch of the Changwon District Prosecutor's Office announced that it has formally indicted 47-year-old, identified by her surname A, on murder charges.

A is accused of leaving her two-day-old daughter, infant B, in the front seat of a parked car with the engine turned off and windows open for an hour and a half starting around 5:15 p.m. two days after giving birth to the baby girl in January 2016 during the peak of winter, causing her to die of hypothermia.

It was confirmed that the average temperature around the scene at the time was 5.73 degrees Celsius (42°F), a condition too harsh for infant B, who was born prematurely with a low birth weight of 2.16 kilograms.

The case almost ended as a perfect crime, but A was caught during a comprehensive local government investigation into unregistered "ghost infants" who were issued temporary newborn management numbers but lacked resident registration.

Goseong County, South Gyeongsang Province, requested an investigation in December 2024, stating that "the safety and whereabouts of the child could not be verified."

During the prosecution's investigation, A reportedly stated, "I was having an affair at the time, and there was a possibility that infant B was the child of the other man, so I committed the crime to hide it from my husband."

In addition, A initially told investigative authorities that she had buried the deceased baby girl in the ground, but later changed her statement to claim she threw the infant into the sea off Goseong County.

The body of the deceased baby girl was ultimately never found.

Initially, charges of abandoning the baby's body could have been applied to A, but the statute of limitations had expired.

Infant B was identified as the sixth child born to A. At the time, A was raising four children with her husband, and due to financial difficulties, she had reportedly put another child born just before infant B up for adoption.
