Jung Yu-jung, who "killed the peer," examined psychopaths...Beyond the category of normal people

Psychopath diagnostic test, out of 40 points for 20 questions...A psychopath with a score of 25 or higher

Jeong Yu-jeong's motive is "I want to kill"...Police conduct a diagnostic test for reinforcement investigation

It is known that the psychopath diagnostic test level of Jung Yoo-jung (23), a so-called "woman killer of Busan age," exceeded the category of normal people.

According to Yonhap News Agency on the 6th, the police are currently analyzing the results of the psychopath diagnosis test conducted on Jeong Yu-jeong. The police are expected to submit the results to the prosecution as early as the 7th after making a comprehensive judgment, believing that Jeong Yu-jeong did not fall into the normal category as a result of the psychopath test.

The psychopath diagnostic test consists of a total of 20 questions, with a score of 40 points out of 40, and in Korea, a psychopath is usually considered when a score of 25 or higher. It is known that the general public scores around 15 points.

In addition to the test score, clinical experts comprehensively judge psychopath diagnosis based on ▲ subject's past track record and growth process ▲ mental health medicine diagnosis ▲ past criminal behavior data ▲ profiler interview results.

The police conducted a psychopath diagnosis test as a reinforcement investigation, believing that although Jung Yu-jeong confessed to the crime, the motive was still not clear.

Jeong Yu-jeong continued to deny the crime after her emergency arrest in the early morning of the 27th of last month, a day after the crime, but confessed to the crime on the 31st of the same month, saying, "I did it because I wanted to kill him."

The prosecution, which received the case on the 2nd, plans to conduct an investigation until the 11th, when the arrest deadline for Jung Yu-jeong ends, and extend the arrest deadline once more if necessary.
