National Forensic Doctor

The anti-drug situation in some areas of the country is still very serious, so much so that the armed police who set up road jams to check vehicles all carry bright long guns.梈

But on the other hand, drug dealers in the city generally keep a low profile, like rats living underground. Except for occasionally scaring people, they do not appear in the eyes of the general public.

Even if it is a criminal police team, if it does not have a few special agents, it is very common that it cannot hand over drug-related personnel when the time comes to hand over tasks.

Therefore, the criminal police dispatched by Changyang City were a little excited when they heard the information from the drug dealers.

Bai Jian couldn't care about this, and immediately said: "The focus of this case is still the murder. We now have two main directions of investigation. First, Wang Xingzhai's interpersonal network must be dug out as much as possible. Second, There should be at least two mobile phones in Wang Xingzhai, and they may have different names, so we need to find them out."

Everyone nodded after hearing this.

Nowadays, a person's mobile phone, in a certain sense, has the property of replacing the person. Through mobile phones and mobile phone verification codes, almost all of a person's information and communication channels with the outside world can be modified and controlled.

The mobile phone number in Wang Xingzhai's own name, and with the assistance of the Internet Security Team, it was easy to verify the number, text messages, and information in online chat software such as WeChat, Momo, and Tantan. Its content is basically about talking about sex...梈

As far as Wang Xingzhai's consumption situation is concerned, he must have an income channel. If Wang Xingzhai is really a drug dealer, it would not be surprising that he has a second and third mobile phone.

If his other cell phones could be found, the case would be relatively easy to solve.

Seeing that everyone agreed, Bai Jian immediately started assigning tasks.

Jiang Yuan volunteered to go to Wang Xingzhai's home to investigate.

Crime scene investigation was originally his skill. As for other tasks such as going to hotels to investigate, looking for prostitutes, and asking about nightclub Tiancai and Facai brother according to the WeChat list, Jiang Yuan himself was not very interested, so he left it to others. Just do it.

Yanlord Marina Lake.

The landlord of the house rented by Wang Xingzhai arrived earlier than the police. He stood in front of his house and did not dare to go in.梈

The police had already reminded him when they called him that middle-class people with families and jobs have always been quite obedient.

As usual, Mu Zhiyang asked a few questions, made a simple note, and came over to report to the neatly dressed Jiang Yuanlai, saying: "There should be no problem with the landlord. An employee of a local state-owned enterprise sold the welfare housing allocated by his previous unit four years ago. , bought a new house in Yanlord, rented it out after renovation, it’s 180,000 yuan a year, which is higher than my salary!”

"The rental-to-sale ratio here is good." Jiang Yuan commented with a professional eye.

Mu Zhiyang thought of Jiang Yuan's background, and immediately stopped the complaints that were about to come out, coughed twice, and said: "Wang Xingzhai should only plan to stay for a year. After he usually goes to nightclubs, he goes to hotels. There are only a few He will bring over his frequent sex friends. I guess after the breakup, he will have to change his place to live."

"If the identity is correct, he would change places from time to time without his gangsters making trouble." Tang Jia was originally a police officer in Changyang City, and he also came to the scene now.

Jiang Yuan just nodded and asked the security guard of the community to serve as a witness. He took two trace inspectors from Changyang City and began to conduct on-site investigation.

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

Wang Xingzhai also hired housekeeping aunts to do some work, but they mainly involved sweeping and mopping the floor and organizing items. DNA could easily be extracted from toothbrushes, combs and other items in the bathroom. The sheets, floor and bedside tables were also the focus of the search.

Jiang Yuan also carefully wiped the cabinets hanging everywhere.

He did it slowly and made detailed marks. In the opinion of the other two mark inspectors, it was a bit too trivial and a waste of time.

Jiang Yuan remained unmoved.

He is not from a traditional trace inspection background, and he does not have a trace inspection master to guide him in his work. He just has a purely technical thinking. In other words, he just relies on his strong skills to get an A draw, but because the output is too high, even if he follows his trace inspection, With ten or twenty years of experience and some special skills, I can only follow and do things silently.

Silent and unwilling to speak.

Indiscriminate bombing actually sounds quite weak, but if you switch to carpet bombing, it feels a bit powerful.梈

Jiang Yuan's trace inspection was equivalent to carpet bombing from beginning to end, without skills or emotions, just output after output.

This kind of thing is difficult to do with ordinary trace inspection. The efficiency cannot keep up, and the level of detail is actually not up to the mark. What Jiang Yuan did to a wardrobe and take samples may require LV2 trace inspection to scan the room. Two bedrooms and one living room will do.

In addition, it actually requires the cooperation of the laboratory. Jiang Yuan dealt with all serious cases and backlogged cases. It was normal to require several times more inspections. General trace inspections were naturally not so tough.

Jiang Yuan spent more than four hours sweeping the house in Wang Xingzhai.

Before leaving, Jiang Yuan stopped again, called the landlord over, and said, "I remember saying before that after the room was renovated, it was rented to Wang Xingzhai. There were no tenants before, right?"

"No."

"The dining table and chairs there are a bit worn." Jiang Yuan pointed to a dining table with six chairs.梈

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, with its back to the kitchen, and three chairs on one side. The three chairs in the adjacent living room outside are very convenient and can be used for sitting at any time. The side next to the kitchen is a little more tense. If there are no guests on a daily basis, the two innermost chairs should be No one uses it.

But from the current point of view, the two outermost dining tables and chairs are obviously commonly used. The backs and legs of the chairs have heavy signs of dragging, which is also one of the focuses of Jiang Yuan's previous collection. Presumably it is also because Wang Xingzhai dines every day.

However, the innermost chair also has many signs of use, which is a bit unconventional. Unless Wang Xingzhai has a particularly favorite posture, he often needs a chair to match it - even so, using the innermost chair is a bit too special...

The landlord was only worried that he would be implicated. After taking a look, he quickly said: "He bought the dining table and chairs himself, and he brought everything in the kitchen and restaurant himself."

"Take it out and study it again." Jiang Yuan motioned for the camera to come forward and keep filming.

The two innermost chairs were taken out, and it was obvious that the innermost chairs were used more frequently. While the middle chair still had rough edges, the innermost chair's legs and feet were already worn.梈

Jiang Yuan and others had noticed this when they were scanning the evidence just now, but they could not find any problems after careful observation. They speculated that the position of the chair might have been changed, but they did not go into details.

However, after scanning the house with four bedrooms and two living rooms, there is nothing illegal at all. Then we have to go back and question the small things before, such as this set of tables and chairs.

The two tracers and Mu Zhiyang turned the two chairs over and studied them for several minutes, but they couldn't find anything like a mechanism.

"There seems to be no problem?" A trace examiner twisted and broke it and decided to give up.

During this process, Jiang Yuan was also observing the marks on the chair, and the more he looked at it, the more he felt something was wrong.

He didn't take it over to try to find a mechanism or anything, he just said: "Cut it open."

Some very intricately designed mechanisms may not be found even with high-level trace inspection. Not to mention the exquisite and beautiful wooden utensils in ancient China, just take a small child-proof medicine bottle or Listerine mouthwash. Many people can't open it in the correct way after thinking about it for several minutes.梈

For some more sophisticated lighters, such as zippo and other special models, it is normal for an unfamiliar person to feel them for a long time and not know how to start a fire.

However, search is not just a puzzle game. Search is a real open world game. If Jiang Yuan feels something is wrong with the chair, he can split it open and take a look. If he finds something, it is best. If he can't find it, he can't find it. How about it.

It’s hard to say what kind of units have a positive image in modern times. Back then, the Japanese invaders, puppet troops and spies conducted searches in the same way.

A tracer picked up an adze used for trace inspection and cracked a table leg open with a few clicks.

Empty.

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

With a click, the leg was smashed open, and there were metal components inside, as well as more bags of small white pills.梈

"Take photos, collect evidence, and make phone calls." Jiang Yuan gave the order feeling slightly relaxed.

Finally, something was gained. From his point of view, this showed that the main blocking point for the murderer was indeed the buried body. The body was found, the source of the body was confirmed, and the elimination of traceable clues was not so detailed.

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

Mission progress: 352/X

Two more points were added than when Jiang Yuan saw it before.

Jiang Yuan looked at the two trace inspectors next to him with much gentler eyes.

The two trace inspectors were full of emotions and excited when they were seen.梈

The trace inspection using a hand-held planer was even more fun. I treated it as a new discovery to make the leader happy and realize his professionalism.
