Chapter 455

The anti-drug situation in some parts of the country is still very severe, so the armed police who set up checkpoints on the highway to check cars all carry bright long guns.

But on the other hand, drug dealers in the city generally keep a low profile, like mice living underground. Except for occasionally scaring people, they do not appear in the public's field of vision.

Even if it is a criminal police team, if you don't specifically raise a few special situations, it is very common to not be able to hand over drug-related personnel when it comes to the task.

Therefore, the criminal police sent by Changyang City were slightly excited when they heard the information about drug dealers.

Bai Jian couldn't care about this, and immediately said: "The focus of this case is still the homicide case. We now have two main investigation directions. First, Wang Xingzhai's interpersonal network must be dug out as much as possible. Second, Wang Xingzhai should have at least two mobile phones, and it is likely that he used other names, so we must find them."

Everyone nodded when they heard it.

In a certain sense, people's mobile phones today already have the attribute of replacing themselves. Through mobile phones and mobile phone verification codes, almost all of a person's information and external communication channels can be modified and controlled.

With the assistance of the network security brigade, Wang Xingzhai's mobile phone number under his own name was easily implemented, including the number, SMS, and information in WeChat, Momo, Tantan, and other online chat software. The content was basically chatting...

Judging from Wang Xingzhai's consumption situation, he must have an income channel. If Wang Xingzhai is really a drug dealer, then it is not surprising that he has a second or third mobile phone.

If his other mobile phones can be found, the case will be relatively easy to solve.

Bai Jian saw that everyone agreed and immediately began to assign tasks.

Jiang Yuan took the initiative to ask for orders to investigate Wang Xingzhai's home.

Crime scene investigation was originally his skill in starting his career. As for other tasks such as hotel investigation, visiting prostitutes, and questioning nightclub beauties and hair-cutting brothers according to the WeChat list, Jiang Yuan himself was not very interested, so he left it to others to do.

Renheng Binhu.

The landlord of the house rented by Wang Xingzhai arrived earlier than the police, and stood in front of his house, not daring to enter.

When the police called him, they had already reminded him. Middle-class people with families and businesses are always very obedient.

Mu Zhiyang asked a few questions as usual, made a simple record, and came to report to Jiang Yuan, who was dressed neatly: "The landlord should have no problem. He is a staff member of a local state-owned enterprise. Four years ago, he sold the welfare housing assigned by the previous unit, bought a new house in Renheng, and rented it out after decoration. 180,000 a year, which is higher than my salary!"

"The rent-to-sale ratio here is not bad." Jiang Yuan evaluated with a professional eye.

Mu Zhiyang remembered Jiang Yuan's background, immediately stopped the complaint that was about to fall out, coughed twice, and said: "Wang Xingzhai should only plan to live for one year. After he goes to the nightclub, he goes to the hotel. Only a few common artillery friends will be brought over. It is estimated that when they break up, he should change places to live."

"If the identity is true, he will change places from time to time without artillery friends making trouble." Tang Jia was originally a police officer in Changyang City, and he also came to the scene.

Jiang Yuan just nodded, let the security guard of the community be a witness, and took two trace inspectors from Changyang City to start the crime scene investigation.

The home of a bachelor looks very simple at first glance. A bachelor who is single 6 times a week is also a bachelor.

Wang Xingzhai also asked a housekeeping aunt to do things, but that was mainly sweeping and mopping the floor and organizing items. Toothbrushes, combs, and other things in the bathroom were easily extracted for DNA. Sheets, floors, and bedside tables were also the focus of the search.

Jiang Yuan also carefully wiped the cabinets hanging everywhere.

He did it slowly and marked it in detail. In the eyes of the other two trace inspectors, it was a bit too trivial and a waste of time.

Jiang Yuan remained unmoved.

He was not from a traditional trace inspection background, and no trace inspection master took him to do things. It was purely technical thinking, or rather, he relied on strong technology to make a flat A, but because the output was too high, the trace inspectors who followed him, even if they had 10 or 20 years of experience and mastered some special skills, could only follow silently.

Not a word, and didn't want to speak.

Carpet bombing sounds actually quite weak, but if it is changed to carpet bombing, it makes people feel a bit powerful.

Jiang Yuan doing trace inspection is equivalent to carpet bombing, sweeping from beginning to end, without skills, without emotions, purely outputting and outputting.

This kind of thing is very difficult for ordinary trace inspectors to achieve. The efficiency cannot keep up, and the detail actually cannot reach—what Jiang Yuan did to a wardrobe and the samples he took might require an LV2 trace inspector to sweep a two-bedroom and one-living room.

In addition, it actually requires laboratory cooperation. Jiang Yuan does all serious cases and cold cases, and it is normal to have several times the inspection needs. Ordinary trace inspectors are naturally not so tough.

Jiang Yuan swept Wang Xingzhai's house for more than 4 hours and swept it once.

Before leaving, Jiang Yuan stood still again, called the landlord over, and said: "I remember before saying that the room was rented to Wang Xingzhai after decoration. There was no tenant before, right?"

"No."

"Then the dining table and chairs inside, the wear and tear is a bit high." Jiang Yuan refers to a dining table with six chairs.

The dining room and living room of the house are connected, and the dining room is adjacent to the kitchen.

The dining table is horizontal, backed by the kitchen, three chairs on one side, and three chairs adjacent to the living room on the outside are very convenient and can be used at any time. The side leaning against the kitchen is slightly tense. If there are no guests in daily life, the two innermost chairs should not be used.

But as far as it is concerned, the two outermost dining table chairs are obviously commonly used, and the back and legs of the chairs have relatively heavy dragging traces, which is also one of the key points of Jiang Yuan's previous collection. I think it is also because of Wang Xingzhai's daily dining.

However, the innermost chair also has more traces of use, which is slightly unreasonable. Unless Wang Xingzhai has a particularly favorite posture and often needs chair cooperation—even so, taking the innermost chair is a bit too special...

The landlord only worried about being implicated, took a look, and hurriedly said: "The dining table and chairs were bought by himself. These things in the kitchen and dining room were brought by himself."

"Take it out and study it again." Jiang Yuan signaled the camera to come forward and keep shooting.

The two innermost chairs were taken out. It was obvious that the inner chair was used more frequently. While the middle chair had burrs, the legs of the innermost chair were already worn.

When sweeping evidence just now, Jiang Yuan and others had already noticed this point, but careful observation did not find any problems. They guessed that maybe the position of the chair was changed, and did not go into it.

However, after sweeping a circle of the four-bedroom and two-living room house, there was nothing illegal, so we had to look back and suspect the small places before, such as this set of tables and chairs.

Two trace inspectors and Mu Zhiyang turned the two chairs over and over for several minutes, but found no mechanism.

"Seems like no problem?" A trace inspector twisted and broke it, and decided to give up.

In this process, Jiang Yuan was also observing the traces on the chair, and the more he looked, the more he felt something was wrong.

He didn't take it over to try to find the mechanism, and said: "Split it."

Some cleverly designed mechanisms, even if it is a high-level trace inspector, may not be able to find them. Not to mention those delicate and beautiful wooden utensils in ancient China, just take a small medicine bottle that is difficult for children to open, or Listerine mouthwash, many people can't take the correct way to open it after studying for a few minutes.

Some more delicate ones, such as certain special models of lighters like zippo, it is normal for people who are not familiar with them to touch them for a long time and not know how to light them.

However, searching is not just playing puzzle games. Searching is a real open-world game. Jiang Yuan feels that the chair is wrong, so he can split it and see. It is best to find something. If he can't find it, he can't find it. What can he do?

It is not easy to talk about the positive image units in modern times. The Japanese invaders, puppet troops, and spies who engaged in searching in those years were the same.

A trace inspector took a planer used for trace inspection, clicked a few times, and smashed a table leg open.

Empty.

He didn't say anything, and continued to smash the second leg.

With a click, this leg was smashed open, and he saw metal components inside, as well as more bags of small white pills.

"Take photos, take evidence, call." Jiang Yuan ordered with a sense of relief.

Finally, there was a harvest. From his point of view, this shows that the main blocking point of the murderer is indeed on burying the corpse. The corpse was found, the source of the corpse was confirmed, and the elimination of the clues of tracing back was not so meticulous.

At the same time, the system page was updated again:

Task progress: 352/X

Compared to when Jiang Yuan looked before, it increased by two points.

Jiang Yuan's eyes looking at the two trace inspectors became much gentler.

The two trace inspectors were full of emotions and excited.

The trace inspector holding the planer played a flower trick, just when the new discovery made the leader happy, and realized his professionalism.
