Wang Yun, a kindergarten teacher was handed a prison sentence by a Chinese court after she was found guilty of poisoning 25 nursery schoolchildren.
The case happened in March of last year when the children were poisoned while having breakfast at school, with one of the children ending up losing his life.
It appears that the teacher had an argument with her colleague over how the children in Jiaozuo city should be handled, with the accused poisoning her colleague’s class.
In the past, Wang had been caught trying to poison her husband with the same poison, sodium nitrite, which is used in explosives and which causes cancer. The man luckily survived.
