A kindergarten teacher who poisoned 25 children, killing one of them, after an argument with a rival staff member has been sentenced to death by a court in central China.

In its official ruling Monday, the Jiaozuo Intermediate People’s Court in Henan province described killer Wang Yun’s motives as “despicable” and “vicious”. “She should be punished severely in accordance with the law,” the ruling said.

The court heard that in the lead-up to the poisoning, Wang had quarreled with another teacher at the Jiaozuo kindergarten over how best to handle the students.

Then, on the morning of March 27, 2019, Wang added nitrite to porridge supplied by the school and intended for the other teacher’s students. Wang had previously bought the nitrite online.

According to the US Centers for Disease Control and Prevention, nitrite is toxic and a likely carcinogen used in fertilizers, food preservation and even munitions and explosives. At high levels, it can stop the human body from properly absorbing oxygen.

Wang had previously been caught trying to poison her husband, surnamed Feng, in February 2017 after an argument. On that occasion, Wang poured nitrite into a glass used by Feng, causing minor injuries.

At the time of the 2019 kindergarten poisoning, one parent told China’s state-run tabloid Global Times he had received a call from the kindergarten saying his child had vomited and fainted. When he arrived, his child was unconscious.

“The vomit was all over (their) pants. There were other children who were also throwing up, and they looked pale,” the father, surnamed Li, said.
