Just outside because of Xu Mo's words, there was a heated discussion and it became a pot of porridge.

The three people in the interrogation room seemed very calm.

Xu Mo said this, the main purpose was to test Fang Mu.

Judging from Fang Mu's overreaction, his previous speculation was preliminarily confirmed.

Therefore, Xu Mo was not in a hurry, just waiting for Fang Mu to take the initiative to ask himself.

Chen Shi is a newcomer, although he has also heard of the 628 case, but he does not know the specific details, so he does not react much.

On the contrary, it was Fang Mu, and his reaction was the biggest among the three.

But he soon realized that he had lost his temper, and quickly adjusted his mind and slowly sat back.

"I'm sorry, I'm a little excited."

Xu Mo nodded and said, "It's okay, although I don't know what the 628 case is, it definitely involves human life, and there is more than one, the police have always attached great importance and persistence to unsolved murders, so I understand you very well." ”

A policeman was actually comforted by the suspect, which made Chen Shi feel very awkward, and even a little incredible.

But whether it was Fang Mu or the police officers in the observation room, they all felt normal.

Because they have had more contact with Xu Mo, similar things have happened more than once.

Although it is a very shameful thing for the police to be comforted by the masses, the police are also human beings, and the pressure is very great, and they will also be tired, angry, and out of shape.

If they are not understood, they will collapse sooner or later.

There are actually not a few police officers who collapse because they are overwhelmed, retire early, or even leave the police force.

After Fang Mu sat down, his expression looked calm, but he twisted his neck and kept stroking his earlobe, obviously he was not as calm as he looked.

Fang Mu was silent for a few seconds before he spoke: "Thank you for your understanding, however, the normal process still has to be followed, I hope you can understand." ”

Xu Mo nodded, and said naturally: "This is natural, after all, every citizen has the obligation to cooperate with the police, and I am a good person who abides by the law, so I will naturally fully cooperate." ”

When Chen Shi heard this, he felt very uncomfortable, and he was a little uncomfortable.

A criminal suspect actually said that he was a good person, so isn't he, a policeman, a saint?

Fang Mu remained silent, he looked at Xu Mo, did not directly ask about the murderer of the 628 case, but once again shifted the topic to the current case.

At this time, Fang Mu also reacted, Xu Mo made such a move, not only to test them, but also to take the opportunity to get more information.

He is not a rookie who is just starting out, so naturally it is impossible for Xu Mo to succeed.

Xu Mo was not surprised by this, after all, there were few real fools in the world.

If Fang Mu was a fool, it would be impossible for him to be a policeman, let alone the captain of the criminal investigation squadron.

So, Xu Mo unusually cooperated with what he knew.

Actually, Xu Mo didn't know much, and it didn't take long for him to finish telling.

After listening to Xu Mo's story, Fang Mu frowned.

According to Xu Mo, he was at the scene of the crime when he woke up, and he was attacked, causing him to lose his memory, so he did not know why he was at the scene of the crime.

But it is worth noting that when Xu Mo woke up, he saw the black shadow man smashing Chen Xuefeng with a hammer.

Judging from Xu Mo's description, Chen Xuefeng should have died or was on the verge of death at that time, falling into a severe coma.

Of course, whether Chen Xuefeng died at that time or not does not matter for the time being.

Importantly, there was indeed a fourth person at the scene, in addition to the two deceased and Xu Mo.

According to Xu Mo, this black shadow man was the murderer who killed Chen Xuefeng and Shen Jiayi.

As for why there were Xu Mo's fingerprints and blood stains on the murder weapon, it was naturally the murderer who stuffed the murder weapon into his hand after attacking him.

But herein lies the problem.

Fang Mu and they have investigated the scene many times, and so far they have only found traces of Xu Mo and the three of them, and there is no trace of the fourth person.

It stands to reason that if the black shadow man is really the murderer of the 628 case, it is indeed easy to clean up the scene.

But the problem is that the scene of Chen Xuefeng's murder can be described as miserable and unbearable.

If the murderer wants to clean up the scene, it is very troublesome and tedious, and it takes a lot of time.

However, the scene of the crime was very empty and very close to the lower town.

The lower town is extremely chaotic, at night, the lower city is more lively than during the day, and someone may appear nearby at any time, how strong does the murderer have to be to spend a lot of time cleaning up the scene?

Even if this person is the murderer of the 628 case and has a strong psychological quality, is he not afraid of exposure?

According to Xu Mo, he was framed by the other party, and the reason was because he had been investigating the 628 case, and the other party was worried that he would be exposed, so he did so.

But in this way, the contradiction arises.

In order not to expose himself, since the murderer chose to kill and then blame Xu Mo, why did he waste time and risk exposure to clean up the scene?

Perhaps, the murderer did this to cover up his traces, but isn't he afraid of being seen by others?

Or is there some special reason for the murderer to be sure that he will not be seen.

What made Fang Mu most puzzled was that the black shadow man could obviously kill Xu Mo directly, which would not only avoid exposure, but also completely solve Xu Mo's trouble.

Why did he choose this time-consuming, laborious, and likely way to expose himself directly?

Of course, Fang Mu also took into account what Xu Mo said, the black shadow man knew him and knew him very well, so he probably didn't kill him out of some concern.

But the more this is the case, the more the black shadow man should kill Xu Mo.

After all, in many homicides, the victims are people who are familiar to the murderer, and even many homicides occur because the murderer chooses to kill because he is worried that his acquaintance will be exposed or betrayed himself.

The more Fang Mu thought about it, the more suspicious he felt, and he even suspected that the so-called black shadow man did not exist, and all of this was made up by Xu Mo.

Before, Chen Shi thought so.

After all, they did not find any trace of the existence of the fourth at the scene.

There is also a possibility that the so-called fourth person was actually a hallucination after Xu Mo was attacked during the crime.

It may also be that Xu Mo's own mental state is problematic, and under external stimulation, he fantasizes about such a person.

But no matter which possibility it is, the core is that there is no fourth person at the scene, and Xu Mo is the real murderer.

It's just that Xu Mo took the illusion as reality because of his amnesia, and he didn't know that the person was actually killed by him.

But there are a couple of issues that suggest that there is likely to be a fourth person at the scene.
