Test results found that a woman in her 20s, a person surnamed Kim, suspected of causing the deaths of two men by giving them drug-laced drinks, falls under psychopath (antisocial personality disorder).
The Gangbuk Police Station in Seoul said on the 4th that an analysis of the Psychopathy Checklist–Revised (PCL-R) evaluation for Kim found that Kim meets the criteria for a psychopath.
The psychopathy diagnostic test quantifies personality traits of psychopaths, such as callousness, impulsivity, lack of empathy, and irresponsibility. It consists of 20 questions, with a maximum score of 40 points.
In Korea, a score above 25 is generally classified as psychopathic, and Kim is understood to have scored above that threshold on this test.
Police sent the results to prosecutors that day.
Kim is suspected of handing drug-laced drinks to three men in their 20s from Dec. 14 last year to on the 9th, causing two to die and one to lose consciousness.
Kim reportedly claimed that Kim mixed medication prescribed at a hospital into a hangover remedy, carried it around, and handed it over after disputes with victims at places such as motels.
However, investigators are leaning toward premeditated murder rather than accidental injury, considering that Kim sharply increased the amount of medication starting with the second crime and searched for terms such as "lethal dose of sleeping pills" and "risks when taken after drinking" using generative artificial intelligence (AI) ChatGPT.
