Why is it that in the case of Dongguan female college students' school toilet being killed, the criminal actually received a suspended death sentence instead of the death penalty? Why can the rich commute the death sentence to a suspended death sentence? This man should be sentenced to death, he does not have the conditions for a light sentence. First molesting and then killing, the circumstances are bad, and he molested another female classmate the day before killing, which is a recidivist and is extremely harmful to society. In any case, you should be sentenced to death. However, there is no death sentence now, on the pretext that it has not caused significant social impact. This completely misreads the law. As a legal worker, I personally think this is a serious illegal act. I suggest that the family of the deceased appeal and request the procuratorate to protest.
