Yoo Young-chul's murder spree was fueled by a deep-seated hatred for women and the wealthy. After a life marked by a criminal record, a broken family, and imprisonment, he meticulously planned his attacks. Operating primarily in Seoul, he would pose as a police officer or a suitor to gain entry to the homes of the rich elderly, binding, bludgeoning, and stabbing them.
