How to do the murder investigation task of Helmet City in The Elder Scrolls 5?

Find the body, ask people around, and reply to the guards.

Go to the castle for help, go to the cemetery and ask the priest's autopsy report.

Find it from the body, follow the blood on the ground (there is a beach at regular intervals), and find the home of the deceased (you can walk directly).

Report to the castle and ask the relatives of the deceased for keys to enter the house for search (or simply pry the lock into the house).

Report to the castle with amulets and notes. The hapless court mage was arrested (one stage of the task was completed).

A few days later, someone was killed in the street, which was a follow-up mission.

The court mage said that when he went to the crime scene, he had divined the time when the murderer committed the crime, and then sent you to patrol the streets.

Finally, I saw a man walking behind a woman with a knife in the street (the guard ignored him and passed with soy sauce). . ), after he stabbed the victim, you killed him and the mission was over.
