Crime scene: 162 mystery solving puzzles to find out who the murderer is

Chapter 7 The Murderer's Name

A young man has died next to a 26-storey building. Police believe the deceased fell to his death from the roof of the building.The police found that the character "森" was written on the palm of the deceased with a pen, as if implying the name of the murderer, but due to limited time, only one character was written.The pen fell on the ground next to his hand, and there were only his fingerprints.It seems that he took out a pen and wrote on the palm of his hand while falling from the building.

The police found five suspects who were also on the roof of the building at the time of the incident based on the reports of the people watching the elevator. They all knew the deceased and found them, but none of them admitted that they were the murderers.

Their names are: Zhang Yu, Liu Sen, Zhao Fang, Zhang Sen, and Yang Yizhou.At this time, the police remembered the word on the palm of the deceased and identified the murderer. Do you know who the murderer is?Why him?

[Answer] The murderer is Zhang Sen.From the point of view of reasoning, first read the names of the five people "Zhang Yu, Liu Sen, Zhao Fang, Zhang Sen, Yang Yizhou" and you will find that if the murderers are Zhao Fang and Yang Yizhou, then the victim only writes in their names. A single character in the name can represent the murderer, because there is no other person whose name has the same character, such as "Fang" in Zhao Fang or "Zhou" in Yang Yizhou, and the names of the three people "Zhang Yu, Liu Sen, and Zhang Sen" There are the same characters in the letter, if the murderer is Zhang Yu, the victim can just write "Yu", so it is not him.Similarly, if it is Liu Sen, only writing "Liu" can represent him, so Zhang Sen is the only murderer left.
