After An Zixi returned to school, he immediately studied the notebook Cheng Xiao gave her.

She temporarily threw everything else behind her.

What she has to do now is to find clues and bring the murderer to justice.

The identity information of the four victims is one aspect. Studying their common points is perhaps the fastest way to find the murderer.

As for the reason why Cheng Xiao and the others did this, An Zixi didn't want to ask, but he could guess a little.

Of course, these are not important. As long as they are reasonable and legal, they can do whatever they want!

Cheng Xiao’s information is very detailed, and there are many internal information that ordinary people cannot access, such as the forensic identification materials, the identity background of the deceased, and the information at the crime scene, which are all sorted out in detail.

These are not stolen, are they? They must have some special and legal channels to get these. Also, don’t forget their family background, the families of these people are not simple!

Besides, has she done less about F method?

An Zixi stared at the information recorded in his notebook and was tranced.

The first victim was from Tianjin, Yang Shuqi, male, seventeen years old, and a quasi-year-old high school student.

He is still a child. He usually studies in school. He has good grades, basically has no social connections, and has no chance to contact people outside the school. How did he be missed by the murderer?

The reason he died was that his head was hit by a blunt weapon, which caused the skull to collapse. Let's put it this way, it was similar to the original owner's death, except that the original owner had intracranial hemorrhage and his skull collapsed.

To put it bluntly, it was just a harsh blow, and the other party did not leave him a trace of vitality.

An Zixi specially studied the fatal wound behind his head. Based on the size and shape of the wound, it should be caused by tools such as hammers.

Carrying the crime tools with you is very purposeful!

Some suspects commit passionate crimes and manslaughter! This situation is often emotional, unable to control one's emotions and temper for a while, pick up something and smash it over, causing death.

Most of the tools for committing crimes are made of local materials, such as stones in the wild, some indoor utensils, flower pots, etc.

Most of the people who commit crimes with tools such as hammers, axes, or wrenches are premeditated.

Yang Shuqi has a clean background. His parents are both intellectuals. They are usually kind to others and get along well with colleagues and neighbors. At least on the surface, they have no enemies.

Of course, all facts must be based on evidence, and some murderers' motives often exceed people's imagination and understanding.

The second victim was Li Dawei, who was a chef who used to work in the canteen of an agency. Later, due to an industrial injury, he left the front line of weighing spoons and became a purchasing agent in the logistics department.

Um……

There is a doubt.

An Zixi found a book and wrote down everything he thought of.

First of all, what happened to this person's hand injury? Could it be that there was a conflict with his colleagues after being injured, which led to a murder case!

Also, purchasing is a fat job, and it has a lot of contact with people in society. Is it possible that this situation is caused by profit-related matters, such as uneven distribution of spoils, or the filling of personal pockets, etc.?

It is also possible.

Moreover, Li Dawei has a bad temper and a too straightforward personality. It is said that he often has friction with people around him, so sometimes he may offend others and he doesn't know it himself.

It's interesting!

Li Dawei was killed by someone's throat slit. The murderer deliberately used his left hand to commit the crime, which was likely to be to confuse the police's attention. Of course, it is not ruled out that the situation was complicated at that time, so he could only use his left hand.

Anyway, the murderer is definitely not a left-handed person.

An Zixi drew two lines under Li Dawei's name, indicating that this person can focus on checking. His social background is more complicated than the first victim Yang Shuqi, and he is a local from the capital, so it is more convenient to check.

The third victim is also a male, Zeng Zhi, who is 66 years old, is the oldest of all victims. He used to be a workshop worker, retired for many years, and his life is relatively simple.

Zeng Zhi's wife died of a cerebral hemorrhage three years ago. Since then, Zeng Zhi, who was already taciturn, has become even more depressed. The neighbors all say that the old man is obviously in his sixties, but he looks like he is eighty years old and doesn't say a few words a day. Sometimes when you say hello to him, he seems to be unable to see anyone.

Anyway, it's a bit unloving.

This old man named Zeng Zhi turned out to be a technical model when he was in the unit. He was a turning worker, and polishing parts was his specialty. He was also the worst of the few people. He was dismembered and died, and his internal organs disappeared.

I don’t know what kind of deep hatred there was, but the murderer actually broke him out.

An Zixi drew a question mark under Zeng Zhi's name and his eyes fell on the last victim.

The six-year-old girl was still a flower bud and was actually killed.

This child was the only dead person who had not seen blood, and she was suffocated to death.

The face is white and blue, and the lips are blue and purple.

If the first few people may have enemies, or have offended people unconsciously without knowing it, then what was this little girl wrong?

Her name is Wenting, she is still in kindergarten. She is obviously innocent and cruelly killed by the murderer.

Fortunately, the child was not violated before his death, which is a blessing in disgrace.

But what is the reason!

Why did the murderer kill her? Could it be that he was seeking revenge from her parents?

Because adults take their anger at their children, this kind of revenge is also common! What's more, it's just psychological problems, so they attack the children.

But Wenting's situation is a bit special.

The three victims before her were all male, and they were of different ages and career backgrounds, so the murderer was not a psychopath. He was likely to have taken the lives of these four victims with a strong purpose.

They must have something in common, what are they?

An Zixi closed the book and fell into deep thoughts.

She wanted to find the murderer and seek justice for the deceased.

Nothing for anything else, just for Xiao Wenting, she is only six years old! Who is so cruel to take her life!

An Zixi spread out all the clues one by one and drew a character relationship feature map on the whiteboard.

The central location is a big question mark.

That's the murderer.

Three days passed quickly, and An Zixi found nothing. She couldn't wait to see Cheng Xiao, wanting to ask about the latest progress of the case.

But Cheng Xiao didn't have any new information to give her.
