Chapter 339：

"what"

Fang Mu was also thinking at first, but came back to his senses after hearing the voice.

"What do you think"

"Uh"

Fang Mu hesitated.

With Fang Ze here, if he gives his own opinion, it seems that there is a kind of feeling of being in a class.

If it's wrong, it's not a shame.

Seeing Fang Mu's concerns, Fang Ze smiled and said, "But it's okay to say, the key to solving a case is to brainstorm, it's not a matter of one person."

Fang Mu is considered to be the best reserve policeman he has ever seen.

If the police can have another talent like Fang Mu in the future, Fang Ze doesn't mind giving him more space to play, so that the other party can grow rapidly.

Hearing Fang Ze's words, Fang Mu hesitated for a moment before saying, "I think the murderer has a strong purpose."

"At the very least, there is no mental problem, but it is very extreme."

"Very likely, with anti-social personality."

Fang Ze's eyes lit up, and he smiled and said, "Continue."

Fang Mu nodded and said, "I think there are two motives for the murder."

"The first is for oneself, and the second is for revenge on society."

"This person must have suffered a lot since childhood, or in other words, suffered a lot of blank stares, which led to his personality."

Tai Wei and Liu Mingyuan looked at Fang Mu.

This analysis sounds good, but it seems to be useless.

Fang Ze didn't care at all, and said: ""

Fang Mu nodded slightly.

Fang Ze said: "Tell me in detail."

"it is good."

Fang Mu thought for a while, and said: "Male, between twenty-five and thirty-five years old, thin and thin, looks non-aggressive, and may even be a good man."

"Longing for blood, my body suffers from a congenital disease."

"This disease is very likely to be incurable, but the murderer imagines that blood can save him."

"Psychologically, extremely distorted, killing people will bring him pleasure."

"I ended up living alone without a stable job."

He stopped talking.

Judging from the current clues, he can only speculate so far.

After listening to Fang Mu's words, Fang Ze looked at him in surprise.

Unexpectedly, this kid was even better than he imagined by a li of money.

Apart from other things, Fang Mu is indeed very talented in criminal psychology.

The image of the murderer portrayed by the other party is basically consistent with his psychological profile.

First is gender.

The crime probability of men is already higher than that of women. Coupled with the gender, age and identity of the deceased, it can be judged that the murderer is very likely to be a man.

Then there is age.

Age is directly related to the degree of physical and mental development of the individual and the amount of social experience.

Therefore, the crime rate of different age groups is also different. Generally speaking, the high-incidence area of ​​crime is between the ages of fifteen and 15 to forty.

The low-incidence area is 15 years old and under 15 years old, and 50 years old and above.

If it is a felony of homicide, the scope can be further narrowed to 20 to 35 years old.

That, coupled with the nature of random serial killings, can continue to narrow the field.

Of course, we're talking about probabilities here, not facts.

Also, being thin.

The murderer has a distorted psychology.

When a person like him commits a crime, he enjoys the pleasure very much.

If conditions permit, the murderer should be more willing to watch the deceased struggle to die.

However, since the murderer chose to tie up the deceased, it shows that he is not a person of good physical fitness.

The target of the crime was a woman, and the murderer was so cautious, as if worried that the victim would struggle out of control.

From this, it can be inferred that the murderer was thin and weak.

I have no self-confidence when facing women.

Finally, there is physical illness.

People don't do weird things for no reason.

Seemingly abnormal behavior, in fact, can find the reason.

Then, why did the murderer drink the blood of the dead? The most likely possibility is that blood has a fatal temptation to the murderer.

In other words, it is very useful for murderers.

What causes the murderer to desire blood? It can only be caused by disease.

And there is no cure for this disease.
