After the autopsy was completed, Jiang Yuan washed himself clean, and then he was stuck in traffic all the way back to the office building of the Criminal Police Detachment of Zhengguang Bureau.
It's already three hours later.
The criminal police from Zhengguang Bureau and the Jiang Yuanji Case Special Team were sitting in the conference room and had already thought about the case.
When Tao Lu heard that Jiang Yuan had come, he counted the time to come to the conference room and sat together to listen to the case.
Tao Lu first asked: "What's the attitude of Avi Airlines? Have the victim's family contacted you?"
No matter which dynasty it is, the case of a victim or not is different.
Needless to say, those cases that have been successfully completed, look at the wrong cases that can be reversed. Behind them are either the victim's family members, or the police or other people involved in the case will not let go, and finally they can reverse the situation.
The same foreigner cases, Burmese cases and Italians’ case pressures are obviously different.
The fourth brigade was the head of the case. Xiao Si immediately stood up and saluted and said, "Avi Airlines' lawyer contacted us and asked about the situation. After we replied, there was no news. The victim's family did not contact us."
"This is how it is." Tao Lu couldn't help but feel a little surprised.
Cui Qishan knew what Tao Lu wanted to ask, and coughed twice and said, "Avi Airlines is probably a little worried."
Tao Lu looked over.
Cui Qishan quickly continued: "The crime scene, which is the apartment where the victim lives, is the apartment provided by Avi Airlines to his employees. Judging from the surveillance video, the victim returned to the apartment at around 9 o'clock that night and did not go out again. There is no surveillance inside the apartment, but there are surveillance on the door and exterior walls of the apartment, so the criminal is likely to live in the apartment."
Tao Lu couldn't help but raise her head: "How many people live in the apartment?"
"28 households, 46 people." Cui Qishan replied: "All of them are employees and families of Avi Airlines, mostly foreigners. 38 are foreigners. There are also a few children."
Tao Lu immediately understood and said, "The criminals are their own people, no wonder-""
"It's almost the same." Cui Qishan said, smiling, looking at Jiang Yuan, and said, "I've taken the footprints of the scene. Team Jiang, please take a look."
"Okay." Jiang Yuan had nothing to be pretentious. The cooperation with Zhengguang Bureau was originally long-term. Besides, I've come here-
Cui Qishan was familiar with Jiang Yuan's habits and was ready. With a wave of his hand, his subordinates quickly released the footprints they had taken on the scene.
If floor tiles are laid indoors, it is relatively difficult to identify footprints. If there is more dust in the room or the soles are dirty, it is fine. If not, many traditional footprint extraction methods will not be so easy to use.
Footprint extraction is essentially similar to fingerprint extraction. The easiest solution is to sprinkle powder and then extract it with tape. However, most humans wear shoes while walking, resulting in less funding for sweat, fluid and other ingredients in the footprint, which increases the difficulty of leaving traces.
Fortunately, Zhengguang Bureau can afford a "laser footprint detector". Although it is difficult to extract, many footprints are still extracted, most of which are barefoot.
"Randomly, more than 5 people appeared in this room." Jiang Yuan looked at all more than 100 footprint photos and said, "One person wearing shoes, Martina herself, and more than three other men."
"Fortunately, I didn't open a party." Cui Qishan was not surprised and said again: "Martina flew from Italy. I have already taken the footprints of the people in the room that day. I will show you the male ones first? There are also the footprints of the people who entered and left the apartment two days ago. I haven't collected them all, because several of them are foreigners, and we don't have relevant data."
Without Jiang Yuan's command, Cui Qishan moved himself.
Jiang Yuan didn't move his butt, just nodded, and the photo in front of him changed.
Jiang Yuan stretched out his hand again, and the Wei Shizhen next to him handed the tea to his hands.
Mu Zhiyang and others twitched their eyes. Some second generations looked harmless, but you didn't know what they were rolling in private.
It is also very difficult to compare footprints, especially when shoes are different, you can often only compare one approximation first and then compare it carefully.
Jiang Yuan asked everyone to continue the discussion. He looked at his footprints for a while and finally wrote two names on the paper.
"The person wearing shoes is also a man, but he is not a resident in the apartment. Another barefoot man is not sure of his identity." Jiang Yuan said, handing Cui Qishan a note with simpler parameters such as height, weight and age.
Cui Qishan hurriedly put away, breathing a sigh of relief, and said, "If this is the case, the murderer will be with these two people who have found their identities. It is not that difficult to choose one of them."
Judging by the time of death, there are only residents in the apartment when Martina died, and the footprints of the residents were collected. Since this is the case, the murderer should be among these two residents.
As for the owners of the two non-appointed residents, they are likely to have entered and exited Martina's apartment before. If they can find the murderer directly, they may not have to investigate their identities.
Xiao Si next to him added coldly at this time: "If you have bad luck, it may be possible that the murderer did not leave any traces."
Xiao Si was one of the cold-faced, stinky and ignorant criminal police officers who were abandoned by the 7th Brigade and finally taken in by the 4th Brigade. Cui Qishan, the captain of the brigade, took over the position late, and the Beijing Central Committee was rare, and Xiao Si was indeed capable, so he could only keep him in the team.
After staying for a long time and being slapped more often, Cui Qishan didn't care, just said, "It's very difficult to kill someone, and it's also strangled. It's difficult to leave no traces. Can the footprints around the household body indicate who the murderer is?"
Cui Qishan also asked. What Xiao Si said was indeed possible.
Jiang Yuan shook his head: "The deceased died in the bed, and the sheets were pulled under the bed, and the footprints were no longer visible - you can try using trace evidence to find evidence, or see if there are any residues such as dandruff."
Cui Qishan responded, looked at Tao Lu and asked, "Do you want to bring the two people whose footprints match up to ask first?"
These are all analysis often done in case handling, and there is nothing special. If you want to say anything special, that is, the victim and the suspect are both foreigners.
However, this is not too strange for the current police detectives. Just do things according to the rules.
Now there is evidence that the two have been in and out of the deceased's apartment room, and it is natural to ask for a question.
Tao Lu agreed after thinking about it, and only reminded him: "Collection of more relevant information and witness testimony, should the two live alone or with others?"
This involves whether there is any evidence of absenteeism. Before Cui Qishan could look carefully, Xiao Sixian next to him said, "The two are married men, one lives with his wife, and the other has a wife and two children."
"Two married men ran into a single woman's apartment room," Tao Lu shook her head: "I'm old and can't keep up with the times. You guys separate their wives and ask carefully so that they won't make perjury."
"Yes." Cui Qishan stood up.
"People involved in the case are not allowed to leave the country. You can also make it clear to them when you take the record. Don't think that if you have done perjury, you can leave it and you will be fine if you don't come back." Tao Lu reminded him clearly.
Liu Jinghui finished reading the relevant information at this time, raised his head and said, "You still have to pay attention to the motivation,
These two people are two men who have left their footprints in the victim's room. They are both in their 30s and their work content is basically not related to Martina. One of them is an engineer and the other is responsible for logistics-related business.
They all have families, so what is the motive for murder?”
"I was threatened with cheating, or I was afraid of being caught, I was afraid of losing my wealth and lifelong support?" Cui Qishan gave an answer casually.
"It's hard to strangle a person." Liu Jinghui turned around with what Cui Qishan had just said, "It's hard for ordinary people to kill so decisively."
Cui Qishan didn't object, but just smiled and said, "You said it makes sense, but if one of the two people didn't kill him, it would be difficult to find the murderer from the apartment building. The murder case of the Oriental Train."
