After the public security organ approves the arrest, it will file a public prosecution with the local people's court in a few days. At that time, the court should use relevant notices to inform family members to appear in court. In this case, if there are no other secrets or operations, the death penalty should be executed immediately according to the situation you described. (1, child 17 years old, there is no problem that children are too young to raise; 2, the cause is related to extramarital affairs, and it does not belong to the situation that can be considered appropriate)

The specific prosecution of the court depends on where the public security organ caught it. It should be prosecuted directly in the local area. If the incident occurs in a foreign country, it may also be handed over to the court where the suspect's household registration is located by the public security organ where the incident occurred.
