Chapter 86 Maybe We Are Just That Lucky
Such a sentence made Xu Dayuan, Liu Yongxin, Da Zhao and Zhou Ning stunned, and they all turned to look at Dr. Lu.
“How do you have the data?”
Dr. Lu waved his hand and sat on the chair in a familiar manner. He took out his thermos cup, drank a sip of wolfberry water, and crossed his legs.
"Why are you so anxious? When we first started debugging here, we asked the city bureau for some bones from unsolved cases for scanning experiments. Among them were the remains of some unidentified deceased persons in this case. I have kept electronic files of both the X-rays and the relevant files."
Zhou Ning looked at Liu Yongxin, and they both fell silent. The people from the Municipal Bureau had just left and had clearly stated that this case had nothing to do with the serial case. Your investigation directly involved those eleven cases. This was a slap in the face.
Xu Dayuan waved his hand.
"You can check if you want. After all, it's led by Dr. Lu. This is just a test. What's the point of thinking too much? It's just a normal comparison.
Moreover, the suspect in the Red Dress serial murder case usually has progressive cases each time. He is constantly summarizing and appreciating his own cases. I think it is normal for him to make any different discoveries.
Let me first tell you about my findings. The deceased, Cheng Chunyan, worked as a warehouse manager at Wanhua International Logistics Co., Ltd. in the bonded logistics park. Because of the recent tax refund policy, logistics companies have been working overtime like crazy for ten days, and get off work at 9:30 to 10 o'clock every day.
Yesterday, March 9, according to Cheng Chunyan's clock-in record, she left the company at 9:38 and rode an electric bike to and from work. The distance from the company to Zhujiazhuang is three kilometers, an L-shaped route.
You see, just come out of the company, turn onto this newly built ecological avenue, walk west for two kilometers and cross the bridge to reach Zhujiazhuang. The place where we found the body is where this L-shaped route turns.
A little further north, the surveillance camera at the company gate can be seen, and a little further west, the surveillance camera on the bridge can also be seen, but now even those are out of reach . It seems that this is not a coincidence. The choice of this location is quite sophisticated and has a strong sense of investigation. "
Dr. Lu didn't understand these, but he still stared at the schematic diagram drawn by Xu Dayuan while holding his thermos.
"Five years, eleven cases, each one had to be carefully planned. He created it as a work of art. Of course, we need to investigate it thoroughly. I think we should check everyone who passed by here at night within a month before last night."
What Da Zhao said makes sense, but if we have to restore and search for every person who appeared in the video for a month, the workload would be enormous.
But thinking about it, in the middle of the night, she had been riding three kilometers by herself for so many days in a row. Was there no one to pick her up? Or someone to go with her?
"Is Cheng Chunyan the only one working in this company in Zhujiazhuang? If she gets off work so late every day, considering how much her sister cares about her, her family should come to pick her up, right?"
Xu Dayuan smiled.
"See? Zhou Xiaozhou is really attentive. Cheng Chunyan has a colleague named Liu Yufeng who lives in the same village as her. He works as a dispatcher at Wanhua International Logistics Co., Ltd. They travel together almost every day. But yesterday, Liu Yufeng had something to do at home and asked for leave in the afternoon, so Cheng Chunyan was left alone."
"She was suddenly left alone? That means the murderer had been waiting here every day, and when he saw Cheng Chunyan was alone, he had evil intentions. How could a single girl be robbed so easily in the middle of the night?"
Zhou Ning's words stunned everyone. It seemed that they were only thinking about how to find the murderer's image and ignored these details. Xu Dayuan raised his hand.
"Don't stop, keep talking."
Zhou Ning was stunned.
"That's all I can think of. Every day there are people following me, but I was left alone yesterday, and then something happened. This is not a coincidence, but someone has been following me for a long time."
Da Zhao came over.
"Transportation, there must be transportation here. After all, we didn't find the deceased's electric bike, right?"
Xu Dayuan shook his head.
"The people who stayed at the beach found the electric bike and will bring it here soon. The bike was thrown into the cracks of the rocks on the east side of the crime scene. The police dog found it."
Da Zhao paused.
"The police dogs have been mobilized. What else have you found?"
At this moment, Xu Dayuan's cell phone rang. Xu Dayuan hummed twice and pointed downstairs.
"The electric car has been brought back. Da Zhao, go and extract the fingerprints and see if you can find anything?"
Da Zhao didn't waste any time and went downstairs carrying the survey box. Xu Dayuan stood up and held Dr. Lu's hand.
"Since you are here, I will not treat you as an outsider. If it is convenient, please show the files I just mentioned to Zhou Xiaozhou and Forensic Doctor Liu. If you can find commonalities, that would be great. Even if you can't find any, you will have more data for your experiments."
"Don't worry, Xu Da. I'll check if the equipment has been debugged. Once it's done, we'll start working."
"I'll arrange a place for you to stay."
Dr. Lu waved his hand.
"Don't worry about these trivial matters. We can go back to the city directly at night. It's not far away, so we can just commute back and forth. The hospital has provided us with a bus, so it's very convenient for us."
"Okay, I'll leave first. Liu Yufeng still needs to check."
Xu Dayuan didn't say any more politeness and left quickly.
Dr. Lu also went next door. After all, he could only start working after the equipment was assembled. He was very interested now, after all, the first experiment was so successful.
Zhou Ning went downstairs with Liu Yongxin. Da Zhao was squatting in front of an electric bike, sweeping it continuously. Zhou Ning went over and observed it carefully.
The electric bike was 60% new, of an unknown brand, with a thick PU windshield. Except for the foot pedal, there was no damage anywhere else. As for the foot pedal, it seemed to have been thrown into a crack between rocks. There was a lot of dirt on the windshield, but there seemed to be a bloodstain on the corner of the brown rear windshield.
Zhou Ning opened the investigation box and raised the magnifying glass to observe carefully. The bloodstain was very faint and could not be found unless observed from such a close distance. But there was a bloodstain here. Could it be that the deceased had hit an electric bike after being injured?
This idea was directly rejected by Zhou Ning.
The deceased's clothes were torn and stained with blood, which showed that he had been raped and abused. If he had managed to escape to the side of the road, he would have left more traces. However, there were no traces at the scene, only bloodstains on two adjacent boulders.
The more this happened, the more nervous Zhou Ning became. Could it be bloodstains left by the murderer?
Thinking of this, Zhou Ning quickly took a photo, then took out a swab, collected a blood sample, and then put it into a bottle. Such smooth movements attracted Liu Yongxin's attention.
"What did you find?"
"Bloodstains. I found bloodstains on the windshield. This location doesn't look like it was left by the deceased. The traces of scratches look fresh. There is dust on it. I think it was stuck there when it was discarded."
Liu Yongxin looked at it carefully and nodded continuously.
"To stop a woman walking alone late at night, pretending to be miserable is a good way."
"ah?"
Da Zhao was confused. He didn't see what happened here. Liu Yongxin waved his hand.
"Fuck you, stay out of my conversation with Zhou Xiaozhou."
Zhou Ning followed Liu Yongxin's guidance and thought of the route map. It was directly displayed on the large transparent screen, and the location of the crime scene was also thoughtfully marked. Was he pretending to be pitiful?
"Master, what I mean is that the murderer saw the deceased coming from afar, and he was alone, so he pretended to be hit by a car, or to be injured and fall, and then made some noise, so as to lead the deceased to come over and have a look.
Seeing the injured person in such a remote place, and it was almost ten o'clock, with almost no people and cars passing by on the road, she was kind enough to check, and then she was held hostage by the murderer and killed directly at the beach? "
Liu Yongxin nodded.
"That's a good supplement. I didn't think about it in such detail, but it must have attracted the attention of the deceased. When he saw the injured person, he felt scared and subconsciously thought that the other person was not dangerous, right?"
Zhou Ning nodded.
However, looking at the bloodstain, Zhou Ning frowned slightly again.
"If this is really the murderer of the Red Dress Serial Killer, would he allow himself to get hurt just to attract other people's attention?"
Da Zhao came over, raised his hand and looked at Liu Yongxin. Liu Yongxin rolled his eyes at the boy.
"Tell me, what do you think?"
"I have no opinion. I just think that if it is really as you guessed, then when the deceased was found alone in such a hurry, he might have thought of it suddenly and left traces on impulse. I think it is not impossible. Maybe we are just that lucky!"
