Look Back at the 1997 Kidnap and Murder in Seoul Committed by a Woman 8-Months Pregnant

I had not heard of this criminal case before, but it is really terrible. How can a pregnant woman kidnap and kill an 8-year old girl?:

On the evening of Aug. 30, 1997, a telephone rang inside an apartment in Seocho District, an affluent neighborhood in southern Seoul. 
  
The voice on the line was calm. 
  
“Is this Na-ri’s house?” the woman asked. “Na-ri is doing fine.”

The next day, the phone rang again. 
  
“Bring a bank card with 20 million won [$14,000] in it,” the woman said. 
  
“I only have cash,” the mother replied, her voice shaking. 
  
“Then you will not be able to see your child,” the caller said and hung up. 
  
Only later would the family learn that this was not a negotiation. Another call that night was traced to a cafe in Myeong-dong, central Seoul. 
  
With no leads, police made the investigation public on Sept. 3. The missing child was Park Na-ri, a second-grade student at a nearby elementary school. Her full name was Park Chorong Chorong Bitnari.  (……………..)

The day after her father came forward, police arrested Jeon at an inn in Sillim-dong, in Gwanak District, southern Seoul. Pesticides were found at the scene. Jeon later told police she had intended to kill herself. Her parents, according to reports, had urged her to do so before her arrest. 
  
She was about a month from giving birth. 
  
Based on Jeon’s testimony, police were dispatched to the basement office of her husband in Sadang-dong, Dongjak District. Her husband worked as a director of children’s theatrical productions. 
  
An officer at the scene later said he nearly slipped on the floor because it was covered in blood. 
  
Na-ri’s body was found inside a hiking backpack.

You can read the rest at the link, but Jeon was sentenced to life in prison and after giving birth her daughter was put up for adoption to the United States.
