It is practically impossible for vicious crimes to disappear. What we need to do is to carefully identify and analyze the incidents that have already occurred and prevent similar incidents from happening again as much as possible. We , JTBC , covered the investigation of Jeong Yoo-jeong, who was handed over to trial for murdering and abandoning her peers.
Reporter Hyo-Jeong Seo and Dr. Ra will tell you what the investigative authorities paid attention to in the way Jeong Yoo-jung committed the crime and in her words and actions after being arrested.

The apartment where the incident took place was quiet.
But people were afraid to even talk about it.
[Apartment official: Because the elderly are shocked… I’m so scared that I come out of my dreams, but please don’t hold the elders and talk to them.]
According to the prosecution, Mr. Jeong메이저사이트 showed cruelty by stabbing the victim more than 110 times with a weapon in the course of the crime.
Traces of damage were also found on parts of the body that did not cause fatal injuries.

Jung’s brutal and elaborate method continued even after the crime.
At the time of the investigation, he said to the prosecutor, “Obviously he killed the victim, but he came back to life and talked to me,” and asked him to “do his mental evaluation.”

[I came because of her grandfather, Yoo-jeong.]
An apartment in Busan where Jeong Yoo-jeong lived alone with her grandfather.

She says that growing up without being properly cared for was the main reason she committed the crime.
Two days before the murder, it was confirmed that she spoke on the phone with her father and said words to the effect of predicting the murder.
