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

"Checked." Zhang Shungu walked to the projector and put a copy of information.

Owner, Lu Zhicun

Mobile phone number, 1583423XXXX

ID number, 370202199308221125

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

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

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

"yes."

Han Bin continued, "In addition, when Team Leader Zhu investigates and monitors, he should pay attention to the time node of 7:46, and use it as a reference to determine the key investigation time."

"knew."

Han Bin looked at Ding Xifeng beside him, "Captain, what else do you have to give?"

Ding Xifeng said, "From the existing evidence, the general time for the suspect to enter the victim's home is probably around 7:30 to 8:00. If this time is in summer, it is not too late. But it starts dark at around 5:00 in winter, and it is already considered evening at 7:30.

At that time, the victim had a dog accompanying him at home. It was almost impossible for the suspect to pick the lock and would definitely be discovered. I think it should be the victim who opened the door on his own initiative, but it was already evening. If he was someone he didn't know, the victim might not have opened the door.

Therefore, it is very likely that an acquaintance commits the crime. When checking the relationships around the suspect, pay more attention to those who have the motivation to commit the crime."

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

Some of them shook their heads, while others remained silent.

"Okay, let's start here first. Let's investigate separately. Team Han will be responsible for the specific tasks." Ding Xifeng said this and looked at Han Bin on the side, "If there is any situation, report to me in time."

"yes."

Ding Xifeng closed the notebook and said, "Okay, let's go."

...

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

He checked the files of the three cases in detail again, and read them very carefully and seriously.

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

He prefers to imitate crimes or hire murders.

First of all, it is about imitating the crime. After the 821 case occurred, some cases and methods of committing crimes were revealed. The latter will continue to commit crimes according to the 821 case model, with the purpose of transferring the charges and the police's investigation direction to the 821 case.

Imitation is just some appearances, but his psychological characteristics are not consistent with the real murderer, and his behavioral performance will be different.

As for hiring and killing, the same way of killing is the same, but the purpose of killing is for money. Whoever gives the money will kill the murderer. The choice of the target is not based on the subjective consciousness of the murderer, and the psychological characteristics are naturally not in line with the serial murderer.

Han Bin used the exclusion method. If it was imitation, then the second case and the third case would be imitated.

The first murderer was called the original murderer, imitating him as the imitator.

The same murder pattern in these three cases means 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 only the third case was committed by the murderer.

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

The first case was done by the original murderer, and the next two cases were done by the murderer.

In response to these three possibilities, Han Bin once again analyzed the traces of the three cases, but found that these three possibilities are still unrealistic, and any two cases do not meet the essential characteristics of the serial murderer.

There are only two possible outcomes. The first possibility is that there is a second imitation murderer, and the three murderers each committed a case.

The second possibility is that these three cases are not imitational crimes.

Han Bin felt that the possibility of two imitating murderers was extremely small, and he was more inclined to the latter.

Then there is only one possibility left, hiring to kill people.

This employment killer is very smart. He deliberately disguised himself as a serial killer to cover up the real purpose of the killer and to protect the employer. As long as the employer is not exposed, his business website will not be exposed and he can continue to hide it.

After receiving the task, the murderer will look for the moral flaws on the target and use this moral flaw as a reason to kill the victim, leading the police's investigation direction to other directions, and preventing the police from tracing the hired person behind the scenes.

Perhaps some people may think that the murderer's three goals have moral flaws, which is too coincidental.

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

Similarly, if a person is deeply jealous and even hired to kill people at all risk, there will definitely be some shortcomings in the murdered person, and he will not slap him in the face.

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

Although there is no tangible evidence, Han Bin still believes in his judgment. He is ready to adjust the direction of the investigation and cannot be led by the murderer to investigate the case by hiring a murderer.

Hiring a murder is different from passionate murder.

The victim and the murderer have a deep connection, either with emotions, grudges or huge conflicts of interest.

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

The victim must know him or her behind the scenes, and can be investigated from the victim's surrounding relationships.

...

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

When Han Bin arrived at the office of the second group, Zhang Shungu was already taking the transcript.

"Korean Team."

"Captain, you are here."

"You guys keep going." Han Bin pulled a chair and sat down.

Zhang Shungu and Feng Na were taking notes for a young man. The man was wearing work clothes, like an employee of JD Express.

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

"It's mine, but my phone was stolen. I re-issued the number this morning."

"When did your phone get stolen?"

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

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

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

"I have two mobile phones, one is a smartphone, and I contact my family. The other is an elderly phone, which is charged for the phone bill and used as a work phone. I remember that after contacting the person who received the express delivery, I put my work phone on the tricycle and I used my smartphone to watch videos."

"Due to the nature of my work, I often call in my work cell phone, but after watching the video for a while, I found that there was no call for a while. I felt something was wrong, so I looked for my work cell phone, but the phone on the tricycle disappeared.

At that time, I didn't expect that my phone would be lost. Even if I couldn't sell it for a few dozen yuan, who would steal it? But after searching for it for a long time, I couldn't find it, so I called the phone number and found that it couldn't be reached. I knew that my phone was really stolen.

Speaking of this, Lu Zhicun sighed and said annoyed, "Who do you think is so immoral? People steal this broken phone? I was really angry at that time because this is my work phone. Without this phone, how can I contact customers?

But it was already seven o'clock and the business hall was closed. I couldn't get the number again. I could only go to one night and went to get the number early the next morning. I didn't even have lunch, so I finally delivered the remaining express delivery."

Zhang Shungu asked, "Yesterday, have you ever been to Moxiang Academy Community?"

"No."

"Do you know someone named He Jun?"

“Don’t know.”

"Where were you last night between 7:46 and 11:00 last night?"

"I went back to the company at around 7 o'clock, explained the situation to our supervisor, and invited the supervisor to have a meal and went home after nine o'clock in the evening."

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

Han Bin sat aside and didn't say anything, just listened quietly, and basically understood Lu Zhicun's situation.

First of all, this case is so complicated that apart from that mobile phone number, Lu Zhicun has nothing to do with this case. If he was really the murderer, it would not be possible to expose it with such inferior means, and it would have no meaning.
