From the gate to the entire courtyard, no suspicious places were found, Yan Tao and two male and female colleagues moved to the door of the building and slowly searched the living room.

One of the two people in the sub-bureau is a male police officer, a technician, and the other is a female police officer, both of whom were sent by Cheng Tiefeng to assist Yan Tao, both of whom were young people, but Yan Tao's horse was the first to look forward.

Yan Tao already has a high reputation in the Spring City police circle, and old criminal policemen like Cheng Tiefeng are ashamed of themselves, and the eyes of these young people looking at him are full of reverence.

This kind of investigation is tantamount to looking for a needle in a haystack, and you don't know if this is a crime scene or if you can find any valuable clues.

However, it seems to be different today, I don't know if this Yan team is confident, or if he is this style, he did it too carefully, and it took almost an hour in the yard, and he got nothing.

The technician unconsciously looked at the time on his phone, it was close to eleven o'clock, and his stomach had begun to scream.

At this time, Yan Tao raised his head and saw the technician's movements, he thought about it and turned back to Duan Wenhu who was following him and said: "Mr. Duan, I'm not going to come here for the second time, our two little colleagues may be hungry, can you trouble Mr. Duan to call the driver and ask him to buy us a few boxes of lunches, and we will pay."

"Maybe Mr. Duan has to accompany us to eat a working meal, no way, it's too far from the city, or invite our female colleague and the driver to go over."

Duan Wenhu smiled bitterly and shook his head: "Team Yan, aren't you sarcastic about me?" Is it because I don't think it through, everyone is busy for my family's affairs, and you can still pay for a working meal? I'll arrange it right away, you can see as you like, I still don't believe you? ”

Saying that, Duan Wenhu turned around and wanted to leave, Yan Tao hurriedly shouted: "Mr. Duan, please wait a minute, you can't leave here, this is the rule, you can call here." ”

Duan Wenhu shook his head and went to the side to make a call.

The young technician said embarrassedly: "Team Yan, thank you, I'm really sorry, it's all my trouble." ”

Yan Tao shook his head and said: "People are iron, rice is steel, how can you do without eating when the time comes, you are still young, your body is more important than work, now let's continue to work, wait for the meal to come, but I am afraid that today will take up the rest time of the two of you." ”

The female investigator smiled: "Team Yan, although we are young, we are also criminal policemen, we are not so squeamish, and such things are frequent, I am very happy to work with a leader like you, you are really thoughtful for everyone." ”

Yan Tao smiled, didn't say anything, and the investigation continued.

The first floor is mainly the living room, dining room, kitchen or something, the ground is covered with very expensive large tiles, cleaned very clean, tidy, basically nothing was found, to the time when the lunch box was sent back, it has been basically surveyed.

After a brief lunch, he continued to survey the bedrooms and study rooms on the second and third floors, especially the master bedroom on the second floor, Yan Tao looked more carefully.

Gently uncovering the sheets and removing the pillows, Yan Tao carefully picked up the hairs with tweezers, long, short, curly, straight, dyed, and black, and his care was better than that of any embroidery girl.

Almost all the hair and dander that could be found were collected by him in the plastic bag, and then he asked the technician to treat the obvious spots with a special potion or even cut them directly with scissors, and collected, this time, he did not have the slightest politeness.

Looking at those spots and curly hair, the young female investigator blushed a little, Yan Tao looked at her seriously, and said: "It seems that you don't have a lot of information about such a scene, this is work, maybe something will become the breakthrough of the case or the main basis for the verdict, so there can't be the slightest sloppiness." ”

The female investigator nodded shyly: "Thank you, Team Yan, you are a good master." ”

It was close to one o'clock in the afternoon, and the survey work was basically over, and several people sat around the dining table drinking the drinks that the driver had brought back when he was buying food just now.

Yan Tao observed Duan Wenhu with the corner of his eye, this is a habit he has developed for many years, in the process of investigating the scene, at the same time secretly observing the expressions of stakeholders, which has helped him a lot to solve major cases.

Although Duan Wenhu is the victim's own brother, the family relationship of a wealthy businessman like the Duan family is greatly discounted, and many interest relationships can dilute the family relationship between them, which is his summary of experience.

In addition, he felt that the case was not necessarily as simple as he initially thought, and that perhaps different people played different roles in it.

He felt it just now, in the master bedroom, when he was seriously extracting evidence, he felt that Duan Wenhu was a little nervous, this was a bit contrary to common sense, the victim was his younger brother, the more meticulous the police handling the case, he should feel relieved, how could he be nervous?

What's so strange here?

In fact, when he was on the first floor just now, he paid special attention to this dining table, which is a rectangular dining table with a marble countertop, very wide, nearly three meters long and about one meter two wide, as a family dining table, it can be described as huge.

In fact, Yan Tao wanted to come to the victim's house to have a look, and there was a purpose, judging from the fact that the victim's genitals were cut off separately, there is a great possibility of murder in this case, so the suspicion of his wife Ma Yulan cannot be ruled out.

Considering that his body was very neatly divided, each piece happened to be split from the bone connection, and the technique was very professional, and Marjoram herself was an orthopedic surgeon, which increased her suspicion.

Assuming that Marjoram killed her husband, then this remote villa should be the best crime scene, and this huge dining table is a good operating table for dividing the human body.

Just now, he had carefully looked at the corners and corners of the dining table, and it was very clean, and there were almost no grease stains, but he still found something, I don't know if he was careful, but also because he used the portable lamp, the multi-band light source survey lamp that was envied by Song Bo, a technician of their detachment.

This is a new type of police survey equipment, he got it from an old classmate in the provincial department, this kind of survey lamp can find different substances according to the different colors of light reflected by different irradiation objects.

Now, he inadvertently pointed to the side of the dining table, close to the bottom of the countertop, and whispered to the technician next to him: "There is a small stain here, the size of a grain of sorghum rice, pale black, maybe it is bloodstains, maybe it is something else, find a way to extract it, can you do it?" ”
