Police will conduct a second evaluation to determine whether Jang (24), who killed a female high school student by brandishing a weapon on a downtown street in Gwangju, is a psychopath (antisocial personality disorder).
Park Sung-joo, head of the National Office of Investigation (NOI), said at a regular press briefing on the 11th that a second profiler interview will be conducted with Jang, who was arrested on charges of murder and attempted murder.
Earlier, police deployed profilers and conducted a Psychopathy Checklist-Revised (PCL-R) assessment on Jang. The score was below the threshold (25 points), and police determined Jang does not meet the criteria for a psychopath.
The Deputy Minister said, "We conducted the first profiler interview and plan to conduct a second," adding, "We will share the comprehensive interview results after completing the second interview."
Around 12:11 a.m. on the 5th, Jang was arrested and later detained on charges of stabbing to death A (17), a second-year high school student, with a weapon on a walkway near a university in Wolgye-dong, Gwangsan District, and wielding a weapon at B (17), another high school student.
