Earlier this week, a kindergarten teacher in central China was sentenced to death for poisoning 25 students by feeding them nitrite-laced porridge over an argument she had with one of her colleagues
In the incident, which happened in the central Chinese province of Henan, the teacher had an argument with her colleague over how best to handle the students, CNN reported on Tuesday, 29 September.
Next morning, the teacher added sodium nitrite, that she had previously bought online to poison her husband, to porridge supplied by the school for the other teacher's students.
One of the students died in January this year after spending 10 months in hospital. The incident had happened in March last year, prompting global headlines and outrage.
According to BBC, while sodium nitrite is often used as a food additive for curing meat, it can be toxic in high amounts as it can stop the human body from properly absorbing oxygen.
On Monday, 28 September this year, the Jiaozuo Intermediate People's Court in Henan province sentenced the teacher — identified as Wang Yun — to death, describing the teacher as "despicable and vicious".
In its official ruling, the court said that she had put sodium nitrite into the porridge of the young students of another teacher in "revenge" after they had "argued over student management issues".
She should be punished severely in accordance with the law.
The teacher had previously poisoned her husband
According to the court, Wang had previously been caught trying to poison her husband in February 2017 after an argument. On that occasion, the husband survived after suffering minor injuries.
The court said that despite knowing that sodium nitrite was harmful, she went ahead "with no regard for the consequences"
The kindergarten teacher concealed her reasons for the poisoning after carrying out the crime and her "motives were despicable", the court said, adding that her "criminal methods and circumstances were exceedingly bad, with especially severe circumstances", according to an AFP report.
In China, death sentences are carried out by lethal injection or by firing squad.
