The results of the psychopath (antisocial personality disorder) diagnostic test for Jang, 24, who killed a high school girl she did not know and injured a male high school student by wielding a weapon, will be released on the 11th.
According to Gwangju Gwangsan Police Station on the 10th, police plan to announce on the 11th the results of the Psychopathy Checklist-Revised (PCL-R) diagnostic test conducted on Jang, who is under arrest on charges of murder and attempted murder.
The diagnostic test was conducted to check for antisocial tendencies, given that Jang committed the crimes against high school students without any particular motive or purpose.
The PCL-R test evaluates 20 items, including impulsivity, lack of empathy, and irresponsibility, and assigns a score. The total score is 40 points, and in Korea, a score of 20 or higher is generally classified as psychopathic.
Police are also continuing an investigation to determine Jang's motive and whether the crime was premeditated. In particular, to verify whether Jang's statement that the crime was spontaneous is true, they are analyzing secured movement routes and activity records and the case is under investigation.
They also plan to examine the facts related to a complaint filed on the 4th by a Vietnamese woman acquainted with Jang at a police station in North Gyeongsang Province.
Around 12:11 a.m. on the 5th, Jang allegedly killed A, a 17-year-old second-year high school girl, on a quiet walkway in Wolgye-dong, Gwangsan-gu, Gwangju, and wielded a weapon at B, another 17-year-old high school student who tried to stop it.
