Prosecutors in Japan are appealing a previous ruling that acquitted Saki Sudo of murdering her ex-husband, Kosuke Nozaki, by administering a lethal dose of methamphetamine. The Osaka High Public Prosecutors Office is dissatisfied with the verdict and has appealed to the Supreme Court. The prosecution presented circumstantial evidence, including that Sudo had searched for terms like "methamphetamine death" on her smartphone.
