Upon admitting the murder, he found out that Hang was keeping secrets to the company and Japan after the business scheme in 2001. When he asked him about the scheme, he didn't answer his question and told him that he is late for his meeting. Angry for not telling him about it, he grabbed his own trophy and bashed him to death.
