Chapter 304 Brainstorming
On the morning of the third day after the incident, the criminal investigation detachment conference room.
Qin Yong looked exhausted.
This sudden murder drained everyone's energy.
Qin Yong only slept for seven hours in the past three days, and the criminal policemen working on the front line basically never came back.
Zhang Hui has been making do in the car for two nights.
"Each group will 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 to enter the apartment building from the night before the crime to 8:30 in the morning."
"We checked everyone's information one by one, and investigated what Lu Chuan did. We conducted a focused investigation on adult males within the range of footprint identification and analysis.”
“We even asked all adult males within the height, weight, and age range to take off their shoes for confirmation.”
"There is a high probability that the murderer...is not in the apartment."
It was not easy for Sun Jun's group to come to this conclusion. In two nights and three days, they collected all the suspects in the apartment. People checked it all over.
However, looking at it now, the possibility of residents in the apartment building committing crimes has basically been ruled out.
"How was the investigation of Zhou Yang's social relationships?"
Ren Qiang shook his head: "We visited Zhou Yang's parents and close friends."
“Zhou Yang has no fixed job and usually lives on the monthly income from his parents.”
“We also investigated his bank account information and found that Zhou Yang has a bad online loan record. .”
"Zhou Yang's social relationships are relatively complicated, and the people he often interacts with are all social idlers who are not doing their jobs properly and are idle."
"According to Zhou Yang's account, Xiao Wang Zhi explained that Zhou Yang does not have a fixed female partner. Friends, but he has several sexual partners."
"Judging from Zhou Yang's economic conditions, we think it is unlikely that he will commit murder for money."
"In terms of vendetta, Zhou Yang. Although Yang doesn't listen to his parents at home, in fact he is just a follower in their circle."
"We can usually get together to drink, play games, etc., and have no criminal record. .”
"The possibility of enemies...especially enemies that can kill people is not high."
"As for love murder, we focused on investigating and interviewing several girls who have a relationship with Zhou Yang."
"There are four people in total, none of whom have fixed jobs. They usually hang out among a group of idle social workers. Sometimes they go to bars to lead dancers, sell drinks and so on."
"None of these four girls have any jobs. They have regular boyfriends and are not married. There are many men who have relationships with them. "At present... the possibility of love murder has been basically ruled out."
Dozens of people from Operations Group 1 and Operations Group 2 have not rested in 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 connections around Zhou Yang do not have the motive to commit the crime.
“Let’s talk about whatever ideas everyone has.”
This is the time to brainstorm and brainstorm.
This is how homicide detection works. Often when there are major clues, the case may not really be solved.
But when there are no clues, or the clues that have been found are all broken, it is very likely that the case will be solved suddenly due to some accident.
"Team Qin, first of all, we can be sure that the murderer should be a habitual criminal or premeditated to commit the crime." Zhang Hui first put forward his own opinion.
“Tell me the basis.”
“The murderer’s fingerprints were not collected at the crime scene, 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 drag marks. The murderer threw Zhou Yang from the rooftop After Bailanhe, he deliberately dealt with the traces of dragging Zhou Yang."
"The fact that the murderer managed the scene so cleanly can only mean two things. Either he committed the crime in advance and planned the murder process long ago. All of them are either experienced or have had the experience of killing people, so they are more cautious."
"I even suspect that the murderer may know that the surveillance in the apartment is damaged, so he killed at this time."< br>
A criminal police officer 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 deposits only amounted to more than a thousand yuan. Are you seeking wealth and murder?"
"For a thousand yuan?"
"As for the murder of love, the team leader just now explained that this possibility is unlikely."
"So, our most important direction now is to find out why the murderer killed Zhou Yang. "
"Old Hu, you are wrong to say that. There does not have to be a motive for killing, and committing a crime for one thousand yuan does not necessarily mean there is no reason. "
"Three years ago, did you forget about the case at the beach where the old man who picked up rags was killed to steal fifty yuan?"
Everyone expressed their opinions when it came to the direction of the investigation of the case.
Qin Yong listened carefully to everyone's guesses and reasoning.
Suddenly, Qin Yong turned his head and looked at Liu Guodong and Lu Chuan, who was sitting next to Liu Guodong.
"Xiao Lu, what do you think?"
As soon as Qin Yong spoke, everyone's discussion ended.
Moreover, they all looked at Lu Chuan, who looked a little shocked.
Lu Chuan is a field investigator 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.
Police reasoning, in fact, plays with people's hearts. It is the insight and analysis of the psychological activities of criminal suspects after handling more cases.
What everyone just said was actually something I have seen before in the process of handling cases.
When everyone speaks, they are supported by their own experience in handling cases. Some opinions 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.
Lu Chuan provided technical support from beginning to end.
Unexpectedly, Qin Yong would ask him for his opinions on the reasoning of the case during the analysis meeting.
“Captain Qin, I think there is still a possibility of seeking wealth and murder.”
"Oh, why do you say that?"
Actually, the discussion just now focused on why the murderer wanted to kill Zhou Yang, killing for love, seeking wealth or revenge?
“Zhou Yang’s bank card only has more than 1,000 yuan, and there are also online loan records, indicating that his financial situation is not good.”
“Everyone who is familiar with Zhou Yang should know , he lives on the money given by his parents every month.”
“I read the inquiry transcript of Zhou Yang’s father. He gives Zhou Yang 3,560 yuan every month, and it is not in the form of transfer. Him.”
Zhang Hui nodded, he knew this best.
He was the one who asked Zhou Yang’s father.
