On the 6th, the Busan Metropolitan Police Agency announced the results of the psychopath test, Jeong Yoo Jung, who was not in the normal category.
With a score of 40, out of 20 questions with a maximum score of 1-2 for each question.
The media say that suspects in major cases like murder show anxious attitudes and behaviors, but Jeong Yoo Jung does not.
Quoting JTBC News, on the 5th, Jeong Yoo Jung showed a calm appearance.
During the 6 days in the detention center, he exhibited abnormal behavior as a suspect in a murder case.
According to joongang.co.kr's report on the 6th, a police officer said about Jeong.
"There's nothing like that (anxious look), it's normal (regarding the food)," said one policeman.
It can be confirmed that Jeong Yoo Jung ate all the food that was distributed three times a day and slept soundly.
The expert also noticed CCTV footage of Jeong Yoo Jung walking with a suitcase right after the murder.
He was dragging the suitcase with such a light step that it was hard to believe that he had taken care of the murder.
"There is something called borderline personality disorder, but it is a very unique sight that leads us to assume that personality disorder exists," said Lee Sujeong, professor of criminology at Kyonggi University.
Quoting todaykorea.co.kr, as a result of digital forensics, it was confirmed that Jeong Yoo Jung had been intensively searching for 'murder' online since February this year, three months before the crime.
At that time, Jung Yoo Jung was preparing for work, and it is known that she developed an interest in murder by watching many crime investigation programs in broadcast media or on the Internet.
Prior to committing the crime, it was also revealed that he had borrowed crime-related novels from the local library after searches such as 'murder', 'murder without a body', and 'murder case'.
Jeong Yoo Jung, born in 1999, lived with his grandfather for about 5 years after graduating from high school without interacting with the outside world. There is no other person's contact information on the phone, nor contact history. /kpopchart.net
