Legal question: When the police catch one of the murderers, how should the victim identify the murderer?

First of all, it is true that your brother is injured now. After the murderer was caught, he said that he would lose money and not go to jail. It is impossible to go to jail without losing money. Now the public security organs should not only investigate the criminal responsibility of the murderer, but also investigate his civil responsibility and demand compensation. You can hire a lawyer. If you are a poor family, you can also apply for legal aid!
