Attending ex-girlfriend's wedding, arresting the groom's officer on the spot

Chapter 304 Brainstorming

On the morning of the third day after the incident, the meeting room of the Criminal Investigation Detachment.

Qin Yong's face was exhausted.

This sudden murder drained everyone's energy.

Qin Yong had only slept for seven hours in the past three days, and the front-line criminal police basically didn't come back.

Zhang Hui has been improvising in the car for two nights.

"Let each group report the situation first."

"Sun Jun, you come first."

Sun Jun also had an extremely tired look on his face.

His group is mainly responsible for checking personnel information inside the apartment building.

"We investigated everyone who swiped their cards into the apartment building from the night before the incident until 08:30 in the morning when the incident occurred."

"I checked everyone's information one by one, and conducted a key investigation on the adult males within the scope of Lu Chuan's footprint identification and analysis."

"Even, we asked all adult men within the height, weight, and age range to take off their left shoes for confirmation."

"The murderer is most likely... not in the apartment."

It was not easy for Sun Jun and his group to come to this conclusion. In two nights and three days, they checked all the suspects in the apartment.

However, looking at it now, the possibility of committing crimes by residents in the apartment building is basically ruled out.

"How is the investigation of Zhou Yang's social relations?"

Ren Qiang shook his head: "We visited Zhou Yang's parents, as well as close friends."

"Zhou Yang doesn't have a regular job, and usually lives on the money his parents send every month."

"We also investigated his bank account information and found that Zhou Yang had bad online loan records."

"Zhou Yang's social relationship is relatively complicated, and the people he often interacts with are all social idlers who are not doing their jobs and doing nothing."

"According to what Wang Zhi told Zhou Yang, Zhou Yang doesn't have a regular girlfriend, but has several sexual partners."

"Judging from Zhou Yang's economic conditions, we think that the possibility of murder is not very high."

"In terms of vendetta, although Zhou Yang doesn't listen to his parents at home, in fact he is a follower in their circle."

"Usually we can get together to drink, play games and the like, and have no criminal record."

"The enemy...especially this kind of enemy who can kill people, the possibility is not high."

"As for the murder of love, we focused on investigating and interviewing a few girls who were related to Zhou Yang."

"There are four people in total, and none of them have fixed jobs. They usually hang out among a group of idle social people. Sometimes they go to bars to lead dancers, sell alcohol and so on."

"None of these four girls have regular boyfriends, nor are they married. There are quite a few men who have relationships with them."

"Currently... the possibility of love killing is basically ruled out."

Action Group [-] and Action Group [-], dozens of people, have not rested for the past few days, trying their best to find out Zhou Yang's situation.

However, judging from the current situation, the people with specific social relations around Zhou Yang did not have the motivation to commit crimes.

"If you have any ideas, let's talk about it."

At this time, it is time to brainstorm and brainstorm.

The case of homicide detection is like this. Often when there are important clues, the case may not be really settled.

But when there are no clues, or the clues that have been found are broken, it is very likely that the case will be solved suddenly due to some accident.

"Captain Qin, first of all, we can be sure that the murderer should be a habitual offender, or premeditated."

Zhang Hui first put forward his own views.

"Tell me the basis."

"At present, no fingerprints of the murderer have been collected at the scene of the crime, and the fingerprints on the aluminum alloy door handle have also been determined to be cleaning and patrolling security."

"The ability to collect fingerprints means that the murderer did not erase the fingerprints, which means that the murderer wore gloves when committing the crime."

"Let's talk about the treatment of dragging marks. After throwing Zhou Yang from the rooftop into the Bailan River, the murderer deliberately dealt with the traces of dragging Zhou Yang."

"The murderer's ability to handle the scene so clean can only explain two points. Either he committed the crime premeditated and planned everything in the killing process long ago, or he is experienced and has murder experience, so he is more cautious."

"I even suspect that the murderer may know that the surveillance in the apartment is damaged, so he killed at this time."

A criminal policeman nodded: "I agree with Zhang Hui's analysis, but there is a fundamental question, why did the murderer kill?"

"When we investigated Zhou Yang's bank account information, we found that his bank deposit was only more than 1000 yuan, did he commit suicide?"

"For 1000 yuan?"

"As for love killing, the team leader just explained that it's not very likely."

"So, our most important direction now is to find out why the murderer killed Zhou Yang."

"Old Hu, you're wrong to say that. There doesn't have to be a reason for the murder, and it doesn't necessarily mean there is no reason to commit the crime for 1000 yuan."

"Three years ago, you forgot the case of the one at the seaside, where you killed the old man picking up rags in order to grab 50 yuan?"

When it comes to the direction of case investigation and handling, everyone expresses their opinions.

Qin Yong listened carefully to everyone's conjectures and reasoned.

Suddenly, Qin Yong looked sideways at Liu Guodong and Lu Chuan who was sitting beside Liu Guodong.

"Xiao Lu, what do you think?"

As soon as Qin Yong's words came out, everyone's discussion came to an end.

Moreover, they all looked at Lu Chuan, who had a somewhat startled expression.

Lu Chuan is a current surveyor and a technical criminal policeman. He has basically no front-line experience, and as far as Lu Chuan himself is concerned, he is not very good at reasoning.

The reasoning of the police is actually playing with people's hearts. It is the insight and analysis of the criminal suspect's psychological activities after handling too many cases.

What you said just now is actually what you have seen in the process of handling cases before.

When everyone speaks, they are supported by their own experience in handling cases. Some views may seem absurd, but they have actually happened.

Lu Chuan attended the meeting today because he questioned the nature of the death at the time and is now a member of the task force.

From beginning to end, Lu Chuan did technical support.

Unexpectedly, at the analysis meeting, Qin Yong would ask him for his opinion on the reasoning of the case.

"Qin team, I think there is still a possibility of murder."

"Oh, why do you say that?"

In fact, everyone's discussion just now mainly focused on why the murderer wanted to kill Zhou Yang, whether it was love, murder, or revenge?
"Zhou Yang's bank card only has more than 1000 yuan, and there are online loan records, which shows that his financial situation is not good."

"Anyone who is familiar with Zhou Yang should know that he lives on the money given by his parents every month."

"I read Zhou Yang's father's interrogation record. He gave Zhou Yang 3560 yuan a month, and it was not in the form of transfer."

Zhang Hui nodded, he knew this best.

He was the one who questioned Zhou Yang's father.
