View StoryThe attack occurred in March of 2019 in a kindergarten school in Jiaozuo city; police were called after the children collectively began vomiting and falling unconscious.
According to prosecutors, Wang Yun's motive was revenge against another teacher at the school, after a dispute over "student management issues".
While sodium nitrate is used as a food additive in processed meats, it can be highly toxic in large amounts.
