Bai Tianqing finally got rid of the enthusiastic Director Wu and came to Yu Qian's side, and Director Wu also leaned his head over while scattering cigarettes for the two. Bai Tianqing hurriedly said that he didn't smoke, and the three of them pushed around in the small space, and the angry Yu Qian wanted to scold his mother, considering that the help of Director Tuowu had just uncovered the formalities, and it was not easy to turn his face if he forcibly suppressed the anger. Director Wu had always seen Yu Qian with a cold face in his impression, and he didn't notice anything wrong.

"Brother Yu, are you watching here? Don't bring it back to the bureau? ”

When the boss heard this, he stopped the operation and turned his head to look at everyone

"Comrade policeman, do you want to take one back? Do you have a USB flash drive? Do you want to buy one from me? ”

"I'll take a look at the surveillance at that time on Friday afternoon, and I'm not in a hurry to copy it." Yu Qian was already a violent temper, but at this time, he only felt an evil fire rushing out of his chest, forcibly endured the anger, and said in the most gentle tone possible, "It's just a supplementary investigation, I'll see if it's necessary first." ”

The boss agreed and started to drum, Lao Wu and Bai Tianqing pulled their necks and looked at the screen from behind Yu Qian, and after a while, the boss adjusted, the surveillance video showed that the time was 5:40 on Friday afternoon, a BMW X5 was steadily parked in the parking space of the community opposite the supermarket, and a young man wearing a casual suit and a black coat stepped out of the cab, and went straight to Building XX after a slight pause. Seeing this, Yu Qian was shocked, revealing an incredible look.

"Wait a minute, rewind frame by frame here, I'll look at his face!" Yu Qian hurriedly patted the boss on the shoulder and commanded

The boss reached out and pressed the pause button, and fell backwards frame by frame, until the man had a relatively complete and clear face when he just got out of the car

"Zoom in!" Yu Qian urged

"This? How to do it? "The boss doesn't usually use the replay function much, so I don't know how to deal with it for a while.

"I'm coming!"

The boss hurriedly turned sideways, Yu Qian bent over and leaned over with his hands for a while, and his straight face was enlarged a little bit, exposing himself to everyone's eyes.

"Who is this?" Lao Wu asked curiously

Yu Qian only felt that the rolling thunder exploded in his heart, this person he not only knew, but also very familiar, it was Li Yaozhan who he had only met on Friday afternoon, claiming to be Ma Wen's boyfriend!

At that time, Yu Qian felt that this man had little to do with the case, and he didn't think that he would be blind! Thinking about it carefully, Li Yaozhan, as Ma Wen's boyfriend, understands the importance of that express delivery, and can easily open the door. But recalling the meeting that afternoon, Yu Qian still couldn't believe that Li Yaozhan was the mastermind behind this case, he didn't even do the most basic disguise and sneaked into the scene of the crime with such a swagger, which was too disobedient!

After thinking about it, Yu Qian decided that it would be not too late to meet Li Yaozhan first, and after thinking about it, Yu Qian straightened up and took out his USB flash drive, instructed the boss to copy the surveillance video to him, and casually talked about some things that he didn't deal with Director Wu, and ran back to the police station with Bai Tianqing.

"Xiaobai, you sort out all the materials and information you collected this morning, copy all the copies to this mobile hard drive, don't leave copies on the computer in the bureau, put them in a drawer and lock them, and then go to dinner, I'll go to the technical department."

As soon as Yu Qian returned to the office, he took out a black and thick mobile hard drive from the locked drawer, and asked Bai Tianqing to sort out the information collected in the morning and hurriedly ran out. Bai Tianqing sat down in front of the computer, sorted out the notes into documents, copied them into the mobile hard drive along with the surveillance video, and looked through Yu Qian's mobile hard drive with strong curiosity and voyeurism, but he was disappointed.

It is neatly arranged in chronological order the relevant information of each case collected by Yu Qian, and if there is anything special, each case is very described, very bizarre, and has a mysterious and strange feeling. At the end, there was a folder with Ma Wen written on it, Bai Tianqing dragged the information into the folder, turned off the computer, locked the drawer and went to eat.

Yu Qian strode down the corridor of the technical department, raised his hand and looked at his watch, it was more than one o'clock in the afternoon, at this time, the old Wang of the forensic office must have just finished his own lunch and sat in the office drinking hot tea while reading periodicals and magazines. Yu Qian stood still at the door of the forensic office, raised his hand and knocked twice, and before anyone inside could respond, he pushed the door open and walked in.

Forensic doctor Wang was sipping hot tea and reading the latest issue of a medical journal, when he was startled by Yu Qian, who suddenly broke in. As soon as Yu Qian walked from his front foot that day, he ran to Liu Zhengming to report the news on the back foot, which led to Liu Zhengming's raid on the criminal police team to suppress Yu Qian from the case analysis meeting. At this time, seeing Yu Qian menacing, he thought that Yu Qian had come to ask the teacher for sin, and there was no place to hide, so he hurriedly went to the chair and put the magazine on his face and pretended to be asleep. But he didn't know that Yu Qian had already seen everything right, and when he saw Lao Wang pretending to be asleep, he didn't shout, he sat opposite Lao Wang with a stool, and watched Lao Wang act without saying a word.

Lao Wang'er heard the sound of a stool, and expected Yu Qian to sit down, but then suddenly there was silence. At this time, the quieter Lao Wang became, the more panicked he became, but Yuqian didn't speak, and he couldn't see it with a magazine on his face. I only felt that the more I suffocated, the more uncomfortable it became, and I didn't see Yu Qian born after a stalemate, so I had no choice but to reach out and tear off the magazine on my face, and yawn and said as if I had just woken up

"Eh, old people, old people, look at the book, you can still fall asleep, it's useless. Huh? Little fish, why are you here? ”

"I don't want Brother Wang to be old, run errands for Brother Wang, see if Brother Wang has anything to inform Bureau Liu, I'll help."

"Uh...... How can I use Captain Yu to run errands, what do I have to find Xiao Liu, I will call him, won't it be over, haha. Lao Wang smiled unnaturally

"But to say, Bureau Liu is young, with diligent legs and feet, and he doesn't like to call if he has anything, so he has to go to the Criminal Investigation Department to talk to me in person." Yu Qian looked at Lao Wang's face and smiled without smiling

"Little fish! You're not here for me, it's not big or small! Lao Wang couldn't hold it back, picked up the shelf of his predecessors, and lowered his posture in a blink of an eye, "I'm not worried that you two brothers will make trouble afterwards, I actually persuaded Xiao Liu to listen carefully to your analysis..."

"Okay, Brother Wang, I haven't made a special trip to tease you." Yu Qian put away his playful thoughts, and said, "I'm here to ask you a few serious things, you only dissected Ma Wen on Friday, I'll ask you a few details here." ”

"Didn't you ask all that day? I've written the rest in the report, and some of the test results won't be available until next Tuesday. But I don't think it's going to be anything special, and if there are no surprises, the case will be closed next week. Lao Wang thought about it and felt that except for the amount of water in his lungs, there was nothing special about it

"Brother Wang, you personally dissected it that day, right?" Yu Qian habitually took out his notebook, "Do you remember all the details?" ”

"I just handled it, there have been no new cases in the past two days, of course I remember it."

"Is there anything special about the deceased's right hand?" Yu Qian hurriedly asked

"Right hand?" Lao Wang raised his head and thought for a while, "It's nothing special, if you have to say it, the calluses on your fingers are a little thick, I guess you have practiced some kind of musical instrument such as a guzheng..."

"Are there any traces of holding something for a long time?"

"How long do you mean by this? If you want to say that you are holding something, then you will not let go of your hand, and since you have let go, then even if there is any trace, it will disappear for a while. If you can still see the mark when you let go of your hand and freeze it, it's not only because you hold it for a long time, but also because you hold it very hard."

"Are there any such marks?"

"No, I can't see it, even if I'm really holding something, I shouldn't have used much force, at least not from the autopsy results." Lao Wang said categorically, "Before the dissection, the body surface characteristics must be recorded in detail, I can be sure of this!" ”

"Is there no trace......" Yu Qian fell into deep thought, although he didn't expect to really find any decisive evidence from here, but Lao Wang's words still made him a little disappointed.

"But... It's a bit weird. Lao Wang suddenly said, "The second knuckles of the four fingers of the deceased's right hand have some slight signs of wear, as if they have rubbed something with a fist. ”

"Like crawling on the concrete floor with your fists clenched?" Yu Qian became excited: "Is it something like this?" ”

"This, I don't know, but if you clench your fist and climb the rough ground, it is very likely that this kind of scratch will appear..."

"Okay, Brother Wang, then I'll come back when the test results come out." Yu Qian asked about the result he wanted, and he was no longer verbose, put away his notebook and walked towards the door, and suddenly turned around and said to the relieved old Wang the moment before he walked out of the door

"Brother Wang, your tea is cold."

Lao Wang was stunned for a moment, looked at the cold green tea, and couldn't help but smile bitterly...

Yu Qian walked out of the forensic office, turned around and plunged into the department next to him, but Xiao Liu in the technical room was matching those fingerprints, and saw Yu Qian come in and hurriedly say hello.

"It's so urgent, Fish Team, I just came back from dinner, and this hasn't been done yet."

"Don't rush this first, I'll ask you a few things." Yu Qian waved his hand and motioned for Xiao Liu to sit down and chat

"What's the matter?"

"Ma Wen's case, have you tested all the things sealed at the scene?"

"Everything that should be checked has been checked, and the results of the test will have to wait for a few more days." Xiao Liu replied after considering his sentence

"I ask you, what do you think about the deceased's bedding, the large amount of sweat stains on the sheets?"

"It is very strange that from the point of view of the remaining sweat stains, the amount of sweat of the deceased before his death is very amazing, and the sweat stains present a standard and clear side lying form, that is to say, the deceased was almost motionless before his death, and the amount of sweat discharged was no less than that after strenuous exercise, it is said that if he just lay still, the amount of sweat in this weather to 1000 ml is already amazing. But as far as I can see, the average sweat of the deceased in the last few days of his life is probably not less than 6000 ml! It's like running a marathon in one day! Xiao Liu couldn't help but sigh, "It's unbelievable that this amount of sweat for several days in a row is only in a quiet state." ”

"Is it possible that it's urine?" Yu Qian asked

"Impossible, the salt distribution is very even, and besides, with this amount of sweat continuously, I'm afraid there will be no urine, and the kidneys are just afraid that they will be drained!" Xiao Liu directly denied Yu Qian's statement

"But your Uncle Wang said that the autopsy of the deceased showed that there was no serious illness."

"This..."Xiao Liu was stunned, "Then we can only wait for the test results, but no matter how you look at it, there are traces of sweat." ”

"Okay, I see, you're going to get busy first." Yu Qian took out a water-based pen and handed it to Xiao Liu, "By the way, compare the fingerprints on this item with the fingerprints at the sewer mouth, if it's different, don't worry about it." ”

"No problem, then the fish team, you can come back tomorrow morning to get the results." Xiao Liu took the pen and returned to the workbench to get busy

Yu Qian walked out of the police station and walked slowly on the side of the road, lit a cigarette and smoked it carefully.

The clues collected in the past two days swirled in his mind, and the results of the surveillance video completely overturned his previous speculation, Li Yaozhan had a perfect alibi, and it was impossible to plan such a meticulous case disguised as an accident hundreds of kilometers away in any case. In fact, Yu Qian was also confused as to why Li Yaozhan went to the scene of the crime, and the only possible explanation was that Li Yaozhan wanted to use his own strength to investigate the cause of Ma Wen's death. It seems that he still underestimates the feelings of this young man who looks like a playboy for Ma Wen, Yu Qian feels that meeting Li Yaozhan now is an important means to open all these mysteries, at least to get Li Yaozhan's fingerprints first, to determine whether he is the one who took the unknown things from the sewer.

After clearing his thoughts, Yu Qian spit out the cigarette in his mouth, threw the cigarette butt into the trash can, and turned around and walked towards the police station......
