Such a sentence made Xu Dayuan, Liu Yongxin, Da Zhao and Zhou Ning stunned, and they turned their heads to look at Dr. Lu.

"How do you have the data?"

Dr. Lu waved his hand, but sat on the chair familiarly, took out his thermos cup, drank a sip of wolfberry water, and Erlang's legs were cocked.

"Why are you yelling, when we first started debugging here, we asked the city bureau for some bones of unsolved cases for scanning tests, including some of the bones of the deceased who have not been identified in this case, whether it is X-rays or related files, I have kept electronic files."

Zhou Ning looked at Liu Yongxin, both of them were silent, the people from the city bureau just left, and they also made it clear that this case has nothing to do with a serial case, as soon as you investigate, you will directly involve the eleven, this is not a proper slap in the face.

Xu Dayuan waved his hand.

"You can check if you want, anyway, Dr. Lu took the lead, this is following the experiment, what's the use of thinking too much, it's just a normal comparison.

And the suspect in the red-clothed serial murder case, his case is generally progressive every time, and he is constantly summarizing, appreciating his case, and what he has found differently, I think it is normal.

Let's talk about my discovery first, the deceased Cheng Chunyan, who worked in Wanhua International Logistics Co., Ltd. in the bonded logistics park, is a warehouse manager, because of the recent tax rebate policy, the logistics company is crazy overtime, it has been ten days, and every day after work is half past nine to ten o'clock.

Yesterday, that is, on March 9, according to Cheng Chunyan's check-in record, she came out of the company at 9:38, commuted by electric car, and returned to Zhujiazhuang from the company for a three-kilometer journey, an L-shaped route.

You can see that it is from the company, turn to this newly repaired ecological avenue, walk two kilometers west and cross the bridge is Zhujiazhuang, and the location where we found the body is the location of the turn of this L-shaped route.

A little further north of the company's door of the monitoring can be seen, further west, the monitoring on the bridge can also be arranged, but now it is not out of reach, it seems that this is not a coincidence, this location is chosen, quite level, but also very aware of detection. ”

Dr. Lu didn't understand these, but he was holding a thermos cup and staring at the schematic diagram drawn by Xu Dayuan.

"In five years, eleven cases, each of which has to be carefully designed, he created it as a work of art, of course, it has to be investigated, I think it should be checked within a month before last night, and everyone who passed by here at night should be checked."

Da Zhao's words make a lot of sense, but if everyone who appears in the video in a month restores and searches, the workload is quite huge.

But thinking of the big night, a person rides three kilometers by herself for so many days in a row, is there no one to pick her up? Or someone who travels with you?

"Is Zhu Jiazhuang Cheng Chunyan himself in this company? If she gets off work so late every day, looking at her sister's attitude towards Cheng Chunyan, her family should come to pick her up, right? ”

Xu Dayuan smiled.

"See no, or Zhou Xiaozhou is careful, Cheng Chunyan has a colleague named Liu Yufeng and her in a village, in this Wanhua International Logistics Co., Ltd. as a dispatcher, they go together almost every day, just yesterday Liu Yufeng had something at home, and asked for leave in the afternoon, Cheng Chunyan was alone."

"Suddenly left alone? That means that the murderer has been squatting here every day, and when he saw Cheng Chunyan alone, he had a bad heart, so a single girl at night could be robbed casually? ”

Zhou Ning's words made several people stunned, as if they were just thinking about how to find the murderer's image, but ignoring these details, Xu Dayuan raised his hand.

"Don't stop, you go on."

Zhou Ning was stunned.

"No, there is only so much I can think of, there are people who follow me every day, I was alone yesterday, and then something happened, this is not an accident, but someone has followed for a long time."

Da Zhao came over.

"Transportation, there must be transportation here, after all, we didn't find the deceased's electric car, right?"

Xu Dayuan shook his head.

"The people left at the beach found the electric car, and it was transported over after a while, and the car was thrown in the crack in the stone on the east side of the crime scene, and the police dog searched for it."

Da Zhao paused.

"All the police dogs have been mobilized, what else have you found?"

At this moment, Xu Dayuan's mobile phone rang, Xu Dayuan made two hmm-hmm, and pointed downstairs.

"The electric car is shipped back, Da Zhao will go and extract fingerprints to see if there are any finds?"

Da Zhao didn't talk nonsense, and went downstairs with the survey box, Xu Dayuan stood up and took Dr. Lu's hand.

"Since my brother is here, I won't treat you as an outsider, the files I just mentioned, if it's convenient, I'll show Zhou Xiaozhou and Forensic Liu, if you find the commonality, it's better, even if you can't find it, don't you have more data for the test."

"Don't worry, Xu Da, I'll see if the equipment is debugged, and we'll start working when it's done."

"I'll give you a place to stay."

Dr. Lu waved his hand.

"Don't worry about these trivial things, we go back to the city directly in the evening, anyway, the distance is not far, just commute back and forth, anyway, the hospital is equipped with a bus, we are very convenient."

"Okay, then I'll go first, Liu Yufeng still has to check."

Xu Dayuan didn't be polite anymore and left quickly.

Dr. Lu also went to the next door, after all, the equipment was assembled before he could start working, and he was now full of interest, after all, the first trial was so successful.

Zhou Ning and Liu Yongxin went downstairs together, Da Zhao squatted in front of an electric car, constantly sweeping, Zhou Ning leaned over and took a closer look.

The electric car is sixty percent new, unknown brand, with a thick windshield with PU texture hanging on it, except for the position of the pedals, there is no damage elsewhere, as for the pedals, it seems to have been thrown into the crack of the stone, and there is a lot of soil on the windshield, but there seems to be a blood stain on the corner of the coffee-colored rear windshield.

Zhou Ning opened the survey box and raised a magnifying glass to observe carefully, this blood stain is very shallow, not so close observation, it can't be found, but there is blood here, could it be that the deceased touched the electric car after being injured?

This idea was directly denied by Zhou Ning.

The deceased's clothes were torn, with blood stains on them, obviously abusing them while violating them, so badly injured that if they could escape to the side of the road, they would have left more traces, but there were no traces at all, only blood stains on the two adjacent boulders.

The more this is the case, the more nervous Zhou Ning becomes, is it the bloodstains left by the murderer?

Thinking of this, Zhou Ning hurriedly took pictures, then took out the swab, collected a blood sample, and then put it into a bottle, which attracted Liu Yongxin's attention.

"What did you find?"

"Bloodstains, blood stains were found on the windshield, this location is not like the one left by the deceased, it looks like the rubbing marks are quite fresh, there is dust on it, and it feels like it was sticky when it was discarded."

Liu Yongxin took a closer look and kept nodding.

"It's a good idea to stop a woman who is walking alone late at night."

"Huh?"

Da Zhao looked confused, he didn't see what was happening here, Liu Yongxin waved his hand.

"you, I'll talk to Zhou Xiaozhou and get less involved."

Zhou Ning followed Liu Yongxin's guidance, thought of the road map, which was directly displayed on the transparent big screen, and also intimately marked the location of the crime scene, is it miserable?

"What Master means is that the murderer saw the deceased coming from a distance, and it was a person, and at this time he pretended to have been hit by a car, or was injured and fell, and then made a little noise, so he led the deceased over to have a look.

Seeing the injured person, and it was such a remote place, or was it almost ten o'clock, and there were almost no people and cars passing by on the road, she kindly checked, and then was kidnapped by the murderer and went directly to the beach to be killed? ”

Liu Yongxin nodded.

"That's right, I didn't think about it so much, but it must have attracted the attention of the deceased, and when I saw the injured person, I felt scared, and I subconsciously thought that the other party was not in danger, right?"

Zhou Ning nodded.

However, looking at this bloodstain, Zhou Ning frowned slightly.

"If it was really a red-clad serial murderer, would he hurt himself in order to attract attention?"

Da Zhao leaned over and raised his hand and looked at Liu Yongxin, who gave the kid a blank look.

"Tell me, what do you think?"

"I don't have an opinion, I just think that if it is really like what you guessed, then it was found that the deceased was alone in such a hurry, would he have thought of it temporarily, and left traces of his temporary intention, I don't think it's impossible, maybe we'll be so lucky!"
