The testimony of an alumni came out when Kim Tae-hyun, the suspect in the'Murder Case of Three Mothers and Daughters in Nowon-gu', "was a scary child who was suddenly outraged" when he was in school.



Today (6th) Mr. A, who was a friend of Mr. Kim's school days, said in a media interview, "I was a good friend, but even though I was playing a joke, I suddenly cursed and got angry." That part was scary."



“I also sent a message to my friends who had lost contact with me, saying,'How are you?'. When I actually met, I asked my friends'Can I go to your house today?' I said.



The police today investigated by using a profiler to interview Kim in person.



The profiler plans to review the situation before and after the crime by analyzing environmental factors such as the background of growth in order to understand Kim's criminal sentiment.



In addition, the police plan to comprehensively consider the results of the interview and investigate whether or not there is a psychopathic tendency.



Kim is accused of stabbing three mothers and daughters with a weapon in an apartment in Nowon-gu on the 23rd of last month.



The police are confirming the circumstances in which Mr. Kim carefully planned the crime in advance, such as searching the Internet for information necessary for the murder, and further investigate the exact details.
