After stabbing her, he showed their mother fabricated KakaoTalk chats to convince her not to make a report on his sister.

The mother had initially filed a missing persons report mid Februrary but he had convinced her to cancel it. The fabricated conversation claimed the sister had left for a trip with her boyfriend. The man had even faked concerned messages to his sister’s account.
