In this way, the captain of the first team chatted with Jiang Feng a few more words.

After a brief communication between the two parties.

The captain of the first team immediately made arrangements.

First divide the victims present and stare them separately one by one.

Prevent collusion.

Then, a group of people did not ask questions for the time being.

The captain of the first team followed Jiang Feng, and the two of them put on the spare gas masks that had just been taken down by the police officers who had just run to the police car.

Walked towards the room where Li Xintong was asked from Geng Li's mouth.

At the same time, there are also police officers in the living room on the first floor.

Responsible for collecting all the things that Jiang Feng had just said and keeping them as evidence.

The small building has a total of five floors, and Li Xintong's room is on the second floor.

Jiang Feng and the captain of the first team were wearing gas masks and gloves, and they didn't dare to relax their guard.

Although when they first rushed in, there were police officers in charge of confirming that no one else was present in the building.

But who knows, there will be some trap set by the murderer.

Don't underestimate these little traps or the spoofed little traps you see on TV dramas.

There have been police officers who have had accidents in this area before, so the subsequent police academy cadets have been specially trained and repeatedly taught on the blood lessons of their predecessors.

......

The door to Li Xintong's room was closed.

According to Geng Li and others below, it was because when they found Wu Tingting, they also smelled the smell of rotten eggs and felt that something was wrong.

So he closed the door of Li Xintong's room.

The captain of the first team reopened the door.

Jiang Feng and the captain of the first team entered Li Xintong's room.

In Li Xintong's room, there was nothing.

"Something is wrong, the information from Xiao Liu's side, as mentioned later, Li Xintong entered the subway with a pink backpack." The captain of the first team was surprised.

Jiang Feng said calmly: "Geng Li assigned a room to everyone who came to the party, and the murderer came to Li Xintong's room to kill Li Xintong, but Li Xintong was not in this room at all. ”

"Then Li Xintong either directed and acted in such a play, or he was in Wang Siyu's room at the time, to determine this, just go to Wang Siyu's room later and see if Li Xintong's pink backpack is there."

The captain of the first team nodded approvingly.

Jiang Feng stood still and didn't move, he continued: "The murderer didn't find Li Xintong in Li Xintong's room, does he know the special relationship between Li Xintong and Wang Siyu?" ”

"If you know, if you don't find it here, you will definitely go straight to Wang Siyu next, but what the murderer didn't expect is that the plan he thought was perfect was disrupted by Wu Tingting, who came to find Li Xintong, so he could only flee in a hurry."

"So, did the murderer know about it? Also, why didn't he kill other people, but came to kill Li Xintong? If it is a mutual murder between the murderers, they want to put all the blame on the other party, create the illusion of suicide in fear of crime, and make all the evidence chains of the case match, so that the police have no way to start, but can only choose to close the case, so as to create a perfect crime. ”

Jiang Feng muttered, and then rejected the idea just now: "But this doesn't logically make sense......

The captain of the first team listened to Jiang Feng's analysis, his head felt a little dizzy, and he was going around, what did Jiang Feng want to express?

The captain of the first team said simply and directly: "Li Xintong is the victim of the fourth case, why did the murderer kill her, isn't the reason very simple?" If we were to speculate, didn't you say before that Murderer B was able to imitate Murderer A's crimes, and the imitation was so successful. ”

"It is very likely that he has seen the murder process of Murderer A, and even knows the identity of Murderer A, and knows that Murderer A is going abroad to go overseas, and he is not in China on the day of the Qingming Festival, so he imitated the crime in China."

"If the fifth case is a parody of the crime, the fourth case is the last case of murderer A in China, and Li Xintong is very likely to have the information of murderer A? Or, Li Xintong is the murderer A? Or, Li Xintong and Wang Siyu are the murderers A! ”

Listening to the words of the captain of the first team, Jiang Feng seemed to have a string in his mind that had been hooked.

He fell into deep thought.

When the captain of the first team spoke, the work in his hands was not idle.

He had been paying close attention to the situation in Li Xintong's room.

But there was nothing in this room, and Li Xintong probably even sat here for a short time before leaving the room with his things.

There was one thing that caught the attention of the captain of the first team, though.

"There is also a red wine bottle on this table, is this Li Xintong and Wang Siyu still flirting here, and then go back to Wang Siyu's room? You can play, these two ......."

The captain of the first team held the bottle of red wine, but did not open it easily.

He looked at Jiang Feng on the side, patted Jiang Feng on the shoulder and said, "Don't think about it, all theories have to fall into practice, do you think this red wine bottle will be boring?" After all, in this room, Li Xintong did not leave any traces, but there was an extra bottle of red wine, which is really a bit strange. ”

Jiang Feng's eyes were fixed on the red wine bottle, and he didn't choose to open it.

Because he is now wearing a gas mask, which is so airtight, he can't judge the smell of the wine bottle.

And in Li Xintong's room, he didn't dare to take off his gas mask.

However, Jiang Feng had some guesses in his heart about red wine bottles.

Jiang Feng said: "Captain, don't open this red wine bottle, take it back for testing, and see if you can get fingerprints on the bottle, as well as ...... The bottle of red wine is likely to contain hydrogen sulfide gas. ”

When the captain of the first team heard this, he nodded.

Leaving Li Xintong's room, he handed over the red wine bottle to the police officer in the ventilated place outside, and asked the police to keep and collect the red wine bottle as evidence and take it to the police car.

Subsequently, the captain of the first team returned to Li Xintong's room.

I searched the room again, and I didn't miss any hidden places.

However, in Li Xintong's room, there was basically nothing to find.

Jiang Feng looked at the captain of the first team, thinking about the string that had just been touched in his mind, and he made his request: "Captain, let's go to Wang Siyu's room now and have a look?" ”

The captain of the first team nodded in agreement.

Suddenly, Jiang Feng took the lead in walking towards Wang Siyu's room.

The captain of the first team followed.

When the two arrived at Wang Siyu's room.

When he entered, Jiang Feng's eyes were extremely keen, and he noticed something.

That is, in the trash can of Wang Siyu's room, there is a condom with milky white liquid.

A special pungent fishy smell permeated Wang Siyu's room.

On the table next to him, Li Xintong's pink backpack was impressive.

The captain of the first team touched his nose, looked at Li Xintong's pink backpack, and said, "Good girl, is this still nostalgic?" ”

Just when the captain of the first team sighed.

Suddenly, the voice of a police officer came from inside the intercom.

"Captain, I am the police officer who stared at Wang Siyu, Wang Siyu turned himself in, saying that he was the murderer of the serial murders in Lutan City in the past five years."

“......”
