National Forensic Doctor

After finishing the hotpot meal, everyone returned to the office and started working overtime as expected.

The police officers who didn't have time to run away because they were craving for hotpot were a little annoyed, but no one wanted to run away at this time. They could only take out their own tasks and start investigating along the route they climbed in by climbing the outer wall.

Once the direction has changed, the evidence that needs to be collected and the content that needs to be investigated will change greatly.

For example, when it comes to climbing an outer wall, most people might think that they should have checked the surrounding surveillance cameras a long time ago. In fact, if the word "surrounding" is not limited, it will make people despair.

There may not be many surveillance cameras that can capture the exterior wall of Avi's apartment, but they are not necessarily official surveillance cameras. They may be surveillance cameras installed by private businesses or individuals. Of course, the more likely scenario is that no surveillance camera can capture the exterior wall of Avi's apartment, or the part that can be captured may not capture anyone.

If we want to draw a line for the flow of people around Avi, based on the four nearest intersections, there will be dozens of surveillance cameras involved. If we check them one by one, even if Jiang Yuan is involved and the time limit is tightened, it will still take thousands of hours of police time.

If the judgment of the time of death is looser, for example, it is replaced by the term "death at night", the manpower cost of monitoring the surrounding area will soar.

Of course, as the difficulty of this case gradually increases, the investment of resources will also increase by the same amount. The manpower brought by Jiang Yuan’s backlog case task force alone can make up for the staffing gap in the Zhengguang Bureau.

In addition to collecting surveillance videos and reviewing surveillance, taking more detailed and oppressive statements from people in Avi's apartment is also a heavy task.

The apartment building itself is not big, with a total of 6 floors, and each floor has five, six, seven or eight rooms of different sizes.

Apartment buildings or apartment complexes are very small compared to the size of Beijing, but checking each room to see if there are any signs of prying doors or windows is a very difficult job.

Tao Lu pulled Huang Qiangmin over with him, and before Jiang Yuan began to arrange the direction of the investigation, he said, "Jiang Yuan, if you can avoid entering the house, try not to enter the house. First find the room the murderer has been to and then search the house. This will be better."

Jiang Yuan couldn't help but look at Huang Qiangmin.

Huang Qiangmin himself had been the chief of the criminal police team, so he could understand Tao Lu. He just spread his hands to Jiang Yuan and said, "This will save the trouble of the foreigner asking you for a search warrant."

"Then take them all away from the apartment. There's no need to tell them what we are going to do." Jiang Yuan has handled so many cases, so he has a way.

Tao Lu suddenly felt like he was being tricked by Jiang Yuan, and hurriedly said, "Send someone out, and we'll go in to search. There will be a lot of problems later, especially with such a large-scale search, so we should try to avoid them if possible."

"Let them come out. We won't search the house yet." Jiang Yuan paused, then continued, "Let's check outside first. However, I started by checking the walls and the building because I was afraid that the suspect would wake up and wipe off the marks on the windows."

Tao Lu frowned: "This... the residents have been ruled out as suspects, right?"

"Even if they are victims, they may have various thoughts. We cannot predict what foreigners think." Liu Jinghui came here to wait for evidence. At this time, he said, "The residents may not know the situation. Now that they see our large-scale search, they may ask for help from some residents..."

Tao Lu looked at Liu Jinghui sharply: "Do you think the residents are still involved in the case?"

"What we are discussing is a possibility." Liu Jinghui smiled: "This case involves so many people. To be honest, anything could happen to anyone. Now because the victim is a foreigner, it is difficult for us to investigate her interpersonal relationships, and we don't know if she has any fatal economic dealings. So now we don't know why she died, but..."

Liu Jinghui said "but" and paused out of habit, waiting for two seconds before continuing: "In fact, the murderer put the victim in a sexual asphyxiation position, which means that the murderer is likely familiar with Martina, and people who are familiar with Martina may have some kind of relationship with the residents of this apartment. Therefore, even if the residents themselves have been ruled out as suspects, we should still treat them as suspects."

"You..." Tao Lu couldn't help but point at Liu Jinghui: "What you said is not entirely wrong."

None of them had a deep discussion on this topic, but Tao Lu still made arrangements according to Jiang Yuan and Liu Jinghui's requests.

Suspects, insiders, or groups of people involved in the case are also a very complicated form for the police. Tao Lu felt that Liu Jinghui was still trapped in the Eastern Train murder-like thinking, thinking that there were all villains in the apartment, or that there was a possibility that many people were involved in the case.

If such a thing happened in reality, it would be too horrifying, but Tao Lu had to admit that Liu Jinghui's guess made some sense.

There are many times when men and women like Martina, who are famous and have countless friends around them, also have increasing enemies in their corners.

It is not uncommon for people to kill because of lust. Moreover, it is known that two residents of the apartment have had affairs with Martina. It can be imagined that she must be a popular and envied member of the entire apartment.

In this environment, the killer could have entered the apartment with an accomplice, or by taking advantage of a resident's psychology, or by receiving unexpected help from a resident. Although the saying "a righteous man has many supporters, an unrighteous man has few" is not very appropriate, for the police, many murders actually happened in this way: intentional or unintentional help and indulgence by people around him, intentional or unintentional indifference and permissiveness by people around him...

Because of what happened in the past few days, there were not many people living in the Avi Apartment, so the police started to clear it out. Although there were some arguments, they quickly completed the clearing with the help of Avi Airlines and embassy staff.

At this time, Jiang Yuan started his survey from outside the apartment complex.

The latest novel is published here first!

When he did this, not only the residents but also some reporters waiting outside began to realize the change.

Among the reporters waiting outside Avi's apartment at this time, there are several Chinese reporters and more foreign reporters.

The reporter who was interested in Benli immediately rushed over and asked with a microphone: "Excuse me, do the police think that the murderer entered Avi's apartment from outside?"

To them, murder committed by their own people and murder committed by outsiders are obviously two different concepts.

The police on the scene naturally did not answer the reporters' questions, but just pushed them away.

Jiang Yuan had walked around the courtyard wall before, but did not find any obvious traces.

This time, he looked around again and found a few points that seemed to be true, but he couldn't be sure. The courtyard wall was too low and its material was not easy to leave marks. In the past few days, the dust in the capital had begun to cover up the marks.

Jiang Yuan had to spend a lot of effort to carefully distinguish these points, and he looked at them for a long time before he stood up.

"How is it?" Cui Qishan asked impatiently.

"It is indeed a climbing point." Jiang Yuan nodded, and then slowly said: "It proves that someone did enter by climbing... Let the lift go in."

If he wanted to see the marks on the exterior wall of the apartment, he naturally needed to observe by sticking close to the wall. At this time, he needed things like lifts and cranes to help.

The reason why this project was not done before was naturally because it would make too much noise. However, for the established task force, as long as there is a definite direction and some equipment is used, it is a small matter.
