Chapter 194 Deliberate Blood Footprints
Yang Xuetong went to the kitchen. He had no doubts about Zhou Ning's judgment. Regardless of how strong this team leader was, his observability and comprehensive ability were recognized by the bureau.

Da Zhao got up with difficulty, glanced at the fluorescence on the sink and toilet floor, and then looked back at the shower room.

"This murderer is perverted enough, can't it be that Xing Xiaoli?"

Zhou Ning shook his head.

"Everything is hard to say. If there is only a bloody handprint on the door and the room is cleaned thoroughly, then Xing Xiaoli is the most suspicious. But now that half of the complete scene has been left directly, people will subconsciously think that Xing Xiaoli cannot be the murderer. If so A murderer wouldn't be so stupid.

Oh, half of the site knows to use 84 disinfectant to destroy proteins, and the shower room here is basically an omission from the original site, a typical planting.

But the more this is the case, the more it makes me feel confused. The murderer knows very well what the effect of using 84 disinfectant is, and why did he leave a bloody handprint on the door? "

Da Zhao pondered for a while, shaking his fat head.

"I don't understand, I don't have that kind of brain. I think those who like to watch CSI seem to know that bleaching powder is used to damage the DNA in the blood, so it is most suitable to clean up the scene. It does not need to be professional, but it is too much to use a kitchen knife to dismember the body." Deliberately, it's not like someone who has seen CSI."

Zhou Ning nodded, Da Zhao said that he didn't understand, but he had reached the key point.

"You also feel inconsistent, don't you?"

Da Zhao nodded.

"Let's survey the scene first, and analyze everything after we go back!"

Zhou Ning came out of the bathroom. It seemed that the floor drain came out because of tossing, so the smell of blood and corruption in the whole room was stronger.

When I came to the kitchen, there were several sign boards on the ground. One was a clear shoe print. Blood stains could be seen on the sole of the foot without using luminol. This was the only valid footprint.

"A size 43 shoe, I just found this shoe in the shoe cabinet."

Da Zhao held up a physical evidence bag, a pair of used Nike sneakers, bloodstains could be seen on the edge of the shoes, Zhou Ning took the bag, looked in the direction of the window, and saw no bloodstains, nor stepped on the heels Mark of.

At this time, Yang Xuetong found a box in the cabinet on the north side, opened the lid and shouted loudly:
"The team leader found the saw."

"Take it back and check if there are any fingerprints. If it's done, the scene is considered complete. Let someone guard it and we'll evacuate."

Back at the technical department, Da Zhao went to submit it for inspection in person. After all, there were so many items to be inspected.

Zhou Ning drank a glass of water and quickly ate his boxed lunch. It was already 03:30 in the afternoon. He was so hungry that he was dizzy and everyone was eating.

Right here, Xu Dayuan pushed the door open and walked in.

Seeing Zhou Ning and the others eating, their faces were apologetic.

"Thank you for your hard work. Tan Ran's parents have already contacted. The flight will arrive at [-] o'clock. I have already asked Xiao Zeng to pick him up. I will come over to you in a while. It is time to draw blood and compare it."

Then Xu Dayuan talked about Xing Xiaoli's investigation, and of course, Xing Xiaoli and Tan Ran's phone calls, all of which were also printed out.

Xing Xiaoli's callers were quite mixed, but according to the remarks on his mobile phone and follow-up visits, it was found that these were indeed people who sold and delivered furniture and home appliances.

In Tan Ran's call log, he had calls with his parents and members of the team.

不过在9月7日下午，谭燃的电话就没了通话记录，至于银行对账单，谭燃在2010年11月12日给邢小利有一笔100万的转账记录。

Afterwards, there were quite a few people who swiped their cards for consumption and cash withdrawals. It can be seen that she is a spendthrift. After all, her bank balance from January to September this year alone exceeded 50, and she made four large withdrawals. , one hundred thousand at a time.

As for Building 10 of Enbo Community, there is no monitoring here, but there is a monitoring at the intersection of Building 6 on the east side. Tao Zhenshan has already gone to the property of the community to call for it. After all, today is October [-]th. If it is too late, I am afraid that it will all be washed away.

After listening to Xu Dayuan's introduction, Zhou Ning nodded, finally put two mouthfuls of rice into his mouth, rinsed his mouth and walked to the whiteboard with a pen.

Xu Dayuan is very clear about why he came at this time, and it is better to take the initiative at this time.

Xia Momo drew a floor plan on the whiteboard. The size was completely scaled down according to the actual scale. On it, Zhou Ning marked several positions with a red pen, pointed and said:

"After on-site inspection, we found a gloved bloody fingerprint on the inside of the entrance door, but the color was very light and appeared very abruptly.

The dry area of ​​the bathroom has been carefully cleaned and rinsed with 84 disinfectant, but the shower room has not been cleaned. There are broken saw blades, electric coils, kitchen knives with gaps, hair and some blockages at the sewer mouth.

A saw was found in the kitchen, and the kitchen was also cleaned, but a very clear bloody footprint was left. The shoes were found in the shoe cabinet. Road traces.

As for all the physical evidence, as well as the samples collected at the scene, they have all been sent to the laboratory. Most of these need to be collected for DNA comparison, and the results will come out tomorrow at the earliest. After all, the number is huge.

Through investigation, the cause of death I am giving now is mechanical suffocation. Xia Momo analyzed the neck circumference of the deceased according to the photos just now. It is the same as the electric coil left at the scene, and there are traces of saw blade cutting on the outer skin of the electric wire , apparently when the head of the deceased was cut off, the wire also fell. "

Speaking of this, Zhou Ning paused, Xu Dayuan waited for a long time to see that Zhou Ning stopped talking, and poked him.

"What are you thinking, and I have to think twice? Say what you think, I'll listen to your analysis, and I've heard your introduction, why do you think this murderer can clean up the scene, but didn't do it? Is that what you mean? "

Zhou Ning nodded, this was the part he was most confused about during the on-site investigation.

"Yes, this is what I can't figure out. The dry area of ​​the bathroom was cleaned quite clean, without a drop of blood, and it was sprayed with disinfectant, and even the shower curtain was covered to prevent the shower room from being cleaned.

As for the bloody fingerprints on the inside of the entrance door and the bloody footprints on the kitchen floor, they were more likely left on purpose, and even the shoes were deliberately left on site. We checked at the time and all the shoes on site were size 43. Based on wear and tear, the shoes belonged to Xing Xiaoli.

It seems that the murderer deliberately drew our attention to Xing Xiaoli. After all, Tan Ran and Xing Xiaoli used to be a couple. know them so well?

Of course, Xing Xiaoli's suspicion has not been lifted. After all, according to what Xu Da said, there is no IOU between him and Tan Ran. If Tan Ran dies, he will be regarded as a vested interest. "

Xu Dayuan lit a cigarette, and now he was the first two big.

"You are right. Since you can clean up part of the scene, you can clean up all the places. The keys are shared, and there are too many people in and out. Now everyone in the speed skating team is suspected, from the coach to the players, especially Wang Ying and Xing Xiaoli. Did not reject Wang Ying's liking."

Liu Yongxin has been standing behind Xu Dayuan, nodding after listening to so many analysis.

"I said Xu Da, don't keep staring at my apprentice. He is a forensic doctor. Although he is with a laboratory, the case still depends on you to lead the case. When it is time to check and monitor everyone's whereabouts, go and check. As a result, it needs to come out tomorrow, as for the bones of the deceased, I will accompany Zhou Xiaozhou to look at them again later, is this all right?"

Xu Dayuan smiled, and patted Liu Yongxin on the shoulder. After all the years of cooperation, this little old man still knows himself well.

"It's better for you to understand me. Look at the bones again to see if there is any other information. In fact, I have never understood why the deceased's feet were cut off. If it is because there are special wear marks on the ankles of figure skaters, Or the bones on the feet are deformed. Is this a bit far-fetched?
How should I put it, even if we see protruding bones or marks of wear and tear, for us, it is easier to analyze the occupation of the deceased, and it will not attract more attention. After all, the corpses are thrown into the sea, so what if we find ? "

This sentence made Zhou Ning raise his eyes.

What Xu Dayuan said is very reasonable. He has just studied the ankles and feet of figure skaters. They are not as severely deformed as speed skaters, but the skin at the ankle bone is rough. After all, they wear skates. If this is true, let them see I don't even care much.

But how serious is it that the feet are cut off?
In other words, what kind of characteristics of Tan Ran's feet made the murderer have to do this?
"Xu Da, ask that coach. After all, Tan Ran has practiced figure skating for ten years. I think as an athlete, he needs a regular physical examination every year, and it is a very strict physical examination. I don't know which hospital they did it. We Go get the file, I was at the scene just now, and in the dormitory opposite, I didn't see any medical records or medical examination reports."

Xu Dayuan directly dialed Wang Ligang's phone number, and the call was connected after only three calls.

"Hello."

"Xu Dayuan from our criminal police detachment, where do you give the team members physical examinations every year? Do you keep the relevant files, or do you keep them in the hospital?"

"In the physical examination center of Qindao Central Hospital, we do a lot of things. After all, we need to know the physical condition of the team members at any time. As for the files, they are all with Team Doctor Zhang, but I don't know if there is any information kept in the hospital."

"Per year?"

"Yes, every year, in addition to the normal physical examination, before participating in international competitions, we will do specific examinations, such as urine tests, which are uniformly checked before going abroad."

"Okay, let team doctor Zhang give all the files to our people."

With that said, Xu Dayuan hung up the phone.

Liu Yongxin glanced at Xu Dayuan. As soon as he said this, it was obvious that everyone in the figure skating team was under control.

"The action is very fast, is it all under control?"
