「モンスターを倒した。これで一安心だ」58歳母の首に包丁を刺して殺害→遺体をバラバラに解体…“医学部9浪”の娘（31）が犯行後に取った“驚くべき行動”（文春オンライン） - Yahoo!ニュース

This page excerpts a nonfiction work about a 2018 murder case in Shiga Prefecture involving a daughter who killed her 58-year-old mother. The daughter, who spent nine years attempting to enter medical school, endured prolonged interference and abuse under her mother's control during a prison-like exam preparation period. After being severely scolded for possessing a hidden smartphone a month before the crime, she developed clear murderous intent. She prepared a weapon by attaching a kitchen knife to a back scratcher and hid it, waiting for an opportunity while her mother slept during massage sessions. Despite multiple chances, she hesitated repeatedly before finally acting.
