Lee Soo-jeong, a professor of criminal psychology at Kyungpook National University, appeared on YTN’s “Newswide” on Wednesday and said that the video shows a glimpse of “personality disorder factors.
“It’s very possible that it’s another version of Jung Yoo-jeong (apologizing to the bereaved family),” Lee said, analyzing that “her steps are very light, and she’s trying very hard to achieve the action she’s aiming for.”
“The problem is that this is after the murder has already taken place, so it’s a very uncharacteristically cheerful look,” he said, noting that “when a normal person, even a criminal, kills someone, they’re very panicked and scared, wondering ‘what to do about it,’ and this doesn’t show that fear or panic.”
“I think the prosecution will probably do a psychological analysis at a later date,” Lee said, adding, “It’s a very unique scene that leads me to believe that there’s something called ‘borderline personality disorder,’ which is a little bit different than just ‘psychopath,’ and that there are some personality disorder factors.”
Lee also mentioned “stealing the victim’s identity” as a possible motive. “(The victim) was a popular tutor online, and I think she was trying to steal her identity as a way to overcome her handicap,” Lee told MBC.
