A friend has a secret recipe for treating cowhide moss at home, but he doesn't have a medical qualification certificate. He treated a girl a few days ago. Which girl died? What will happen?

According to the relevant laws, you should bear the corresponding criminal responsibility and civil liability for compensation. In criminal cases, 15 may be more than seven years. It is better to look at the other party's age, income and family factors to compensate, and hope that the victim will not sue. These all need to be identified in the relevant judicial departments whether the deceased has a direct or indirect relationship with your friend. Better find a better lawyer.
