Detective from The Future

Han Bin said, "Have you found out the identity of the owner?"

"I found it." Zhang Shungu walked to the projector and put a piece of information.

Owner, Lu Zhicun

Mobile number, 1583423XXXX

ID number, 370202199308221125

Address, Wuye Community, Jiuhua Road, Chengnan District, Qindao City.

Zhang Shungu continued, "There is another situation to show that Lu Zhicun's mobile phone number is still in use and can be located."

Ding Xifeng said, "Then determine his location as soon as possible and take him to the police station for a record."

"Yes."

Han Bin continued, "In addition, when team leader Zhu is investigating and monitoring, he should pay attention to the time node of 7:46, and use it as a reference to determine the key investigation time."

"understood."

Han Bin looked at Ding Xifeng, "Captain, what else do you want to tell?"

Ding Xifeng said, "Judging from the existing evidence, the approximate time for the suspect to enter the victim's home is likely to be around 7:30 to 8:00. If this time is in the summer, it is not too late. But at 5 o'clock in winter. It started to get dark for many days, and it was already night at half past seven.

At that time, the victim was accompanied by a dog at home. It is almost impossible for the suspect to pick the lock and he will definitely be found. I think the door should be opened by the victim, and it was already night. If it is someone who doesn’t know, the victim may not open the door.

Therefore, there is a high possibility that acquaintances committed the crime. When investigating the surrounding relationship of suspects, pay more attention to those who have the motive of committing the crime. "

Ding Xifeng glanced at his watch, "What else do you want to say about this case?"

Some of them shook their heads, some were silent.

"That's it, the meeting will be here first. Let's investigate separately, and the specific tasks will be taken care of by the Korean team." Ding Xifeng said this, and looked at Han Bin on the side, "If you have any situation, report to me in time."

"Yes."

Ding Xifeng closed his notebook, "Okay, let's end the meeting."

...

Han Bin arranged the task in detail, and then returned to his office.

He checked the files of the three cases in detail again, carefully and carefully.

The victims of these three cases have moral flaws, but none of them are illegal, and the law cannot punish them. On the surface, it is also a condition for the murderer to find the target of the crime.

Han Bin infers the criminal's behavior pattern based on the traces left at the crime scene, further infers the psychological characteristics, and then infers the suspect's next behavior characteristics.

However, Han Bin analyzed the three cases and found that in addition to the appearance of moral defects and Z Peugeot, the three cases did not conform to the psychological profile of the serial murderer.

He is more inclined to imitate crimes or hire to kill.

First of all, let’s talk about imitation. After the occurrence of the 821 case, some facts and modus operandi were revealed. The latter will continue to commit the crime in accordance with the 821 case model, with the purpose of transferring the crime and the direction of police investigation to the 821 case.

The imitation is only some appearances, but the psychological characteristics of him and the real murderer do not match, and there will be differences in behavior.

As for hiring to kill, the way to kill is the same, but the purpose of killing is for money, whoever gives the money, and who the murderer kills. The choice of the target is not based on the subjective consciousness of the murderer, and the psychological characteristics of the serial murderer naturally do not match.

Han Bin used the method of exclusion, if it was imitation, then the second and third cases would be imitated.

The first murderer is called the original murderer, imitating it is called the imitation murderer.

The homicide patterns in these three cases were the same, indicating that one of the murderers committed two cases.

Then there are only three possibilities.

The first and second cases were committed by the original murderer, and the imitation murderer only carried out the third case.

The first and third cases were done by the original murderer. The second case was committed by a murderer. The original murderer felt offended and executed a third case.

The first case was committed by the original murderer, and the latter two cases were committed by the imitation murderer.

In view of these three possibilities, Han Bin analyzed the traces of the three cases again, but found that these three possibilities were still not valid, and any two cases did not meet the essential characteristics of a serial murderer.

With this result, there are only two possibilities. The first possibility is that there is a second imitation murderer, and the three murderers each have made a case.

The second possibility is that these three cases are not imitations.

Han Bin felt that the possibility of two imitation murderers was extremely small, and he preferred the latter.

Then there is only one possibility left, hire to kill.

This hired murderer is very clever. He deliberately pretended to be a serial killer in order to cover up the real purpose of the murder and to protect the employer. As long as the employer does not expose, his business network will not be exposed, and he can continue to hide.

After receiving the task, the murderer will look for the moral flaw on the target, and use this moral flaw as a reason to kill the victim, direct the police's investigation direction to other directions, and prevent the police from tracking down the hired behind the scenes.

Some people may think that the three goals of the murderer are morally flawed, which is a coincidence.

In fact, this situation can be reversed. It is not easy for you to find good students in ordinary schools, but if you go to Tsinghua and Peking University, you can find them with your eyes closed.

In the same way, if a person is deeply hated and even hired to kill at risk, there will definitely be some shortcomings in the slain, and a slap will not sound.

It is not difficult for a killer to find a reason.

Although there is no real evidence, Han Bin still believes in his own judgment. He is prepared to adjust the direction of the investigation and cannot be led by the nose by the murderer to investigate the case by employing murder.

Hiring killing is different from passion killing.

The victim and the murderer will have a deep connection, either emotional, enmity, or a huge conflict of interest.

Professional killers have certain anti-reconnaissance capabilities, and it is not easy to find their whereabouts.

The victim must have known the employer behind the scenes, which can be checked from the victim's surrounding relationship.

...

At five o'clock in the afternoon, Han Bin received a report call, and Lu Cunzhi had been found.

When Han Bin rushed to the second group office, Zhang Shungu was already taking notes.

"The Korean team."

"Captain, you are here."

"You continue." Han Bin pulled a chair and sat down.

Zhang Shungu and Feng Na are taking notes to a young man who is dressed in overalls, like employees of JD Express.

Zhang Shungu continued to ask, "Lu Zhicun, is the phone number 1583423XXXX yours?"

"It's mine, but my phone was stolen. The number was reissued this morning."

"When was your phone stolen?"

Lu Zhicun thought for a while, "It should be around 7 o'clock last night, I don't know the exact time."

"Where did you lose it? How did you lose it?"

"I lost it at the entrance of Changdao District, Nongye Road, and Yongxi District. I delivered the courier, and I was responsible for the courier in that community. I pulled a cart and parked at the east gate and called the person who took the courier. , I took the goods out of the car and waited for them to come to the east gate to pick them up."

"I have two mobile phones, one is a smart phone, to communicate with family members. The other is an elderly phone, which is charged with the phone bill and used as a work phone. I remember that after contacting the delivery person, I put my work phone On the tricycle, I watch the video on my smartphone."

"Because of the nature of my work, my work cell phone often comes in, but I watched the video for a while and found that there was no call for a while. I felt something was wrong, so I looked for my work cell phone, but the cell phone on the tricycle was gone. .

At that time, I didn't expect that the mobile phone would be lost. The broken mobile phone could not be sold for dozens of dollars. Who would steal it? But I didn't find it after searching for a long time, so I called the phone number and found that I couldn't get through. I knew the phone was really stolen.

Speaking of this, Lu Zhicun sighed and said annoyed, "Whoever you said is so wicked, this broken phone is stolen. I was really outraged at the time because this is my work phone. Without this phone, how can I Contact the customer.

But it was already seven o'clock and the business hall was closed, so I couldn't make up the number if I wanted to. I had to last one night. I went to make up the number early the next morning. I didn't even bother to eat at lunch, and finally delivered the rest. "

Zhang Shungu asked, "Yesterday, did you ever go to the Moxiang Academy community?"

"No."

"Do you know someone named He Jun?"

"do not know."

"Where were you between 7:46 and eleven last night?"

"I went back to the company at more than seven o'clock to explain the situation to our supervisor, and then asked the supervisor to have a meal, and then went home after nine o'clock in the evening."

Zhang Shungu asked, "What is your supervisor's name? Who else is in your family..."

Han Bin sat aside and didn't speak, but listened quietly, and he had a basic understanding of Lu Zhicun's situation.

First of all, this case is so complicated. Apart from the mobile phone number, Lu Zhicun has nothing to do with this case. If he is the murderer, it is impossible to expose it by such inferior means, and it has no meaning.

Han Bin is more inclined to believe his words.
