However, evidence is needed to solve the case. Even if what Chen Bai said makes sense, it is useless because there is no evidence.
"Xu Hai, let's go to bed first! Now we can only know what happened after Song Anchun and Zhao Pengcheng complete the bone age analysis."
Early the next morning, Song Anchun found Chen Bai with the autopsy report. Although the cause of death of the girls could not be determined yet, the bone age test report showed that the girls were all around 25 or 26 years old.
"Chen Bai, we have another discovery."
"explain!"
Song Anchun said and took out another report. After Chen Bai took the report, Song Anchun spoke.
"That's right, I checked the doll that was sent to Zhang Zhiyong and Qiao Rui, and I found that the doll's hair seemed to be made of real human hair."
As soon as Song Anchun said these words, Chen Bai immediately became alert.
"Real human hair?"
"Yes, after my testing, the hair on the doll is made of real human hair."
Chen Bai held the report in his hand and looked at the doll beside him. He didn't understand why the murderer did this.
"Okay, I understand. You've been busy all night. You should go and have a rest!"
On the other side, with the help of Xu Hai, Qiao Rui also completed his confession.
"Don't worry, you will stay in our police guest house from now on. It will be very safe there."
Xu Hai didn't dare to tell Qiao Rui that someone might want to take revenge on her. Qiao Rui wanted to ask something but saw Xu Hai's look and didn't speak.
"Okay, then I'll go back first."
"I'll give it to you!"
Qiao Rui wanted to refuse, but Xu Hai still insisted on sending Qiao Rui to the door.
"Captain, this is Wang Qingshan's autopsy report. Take a look at it."
Zhao Pengcheng came to Xu Hai with the autopsy report. When Xu Hai took the autopsy report, the photos in the case file fell to the ground.
"Hey! This person..."
Qiao Rui picked up the photo. Xu Hai watched Qiao Rui frown at the person in the photo and asked casually.
"Is this person your suspect?"
"How come you know him?"
Xu Hai just said something casually because he was reading the autopsy report, but unexpectedly Qiao Rui nodded directly.
"Yes! I know him!"
"you know?"
Xu Hai was a little surprised. How did Qiao Rui know the deceased in this case?
"Wait a moment, come to my office and tell me in detail what's going on."
The two returned to the office, and Xu Hai called Chen Bai. After the three of them sat down, Qiao Rui took out his mobile phone and showed Xu Hai and Chen Bai a photo.
"The girl in the photo is called Ding Wan. She is one of my best friends. One night, it was almost past ten o'clock. Ding Wan called me and asked me to borrow 100,000 yuan. I went without thinking about it, but I didn't expect to wait for me.
After we arrived, there was another man in Ding Wan's family."
Qiao Rui said, pointing to Shen Qiang's photo.
"When I looked at Ding Wan, I felt that this man was not a good person, because Ding Wan seemed very scared at the time, but Ding Wan assured me that he was definitely not a bad person, but when he saw me, this man seemed a little unhappy.
, and then left directly.”
After Qiao Rui finished speaking, Xu Hai glanced at Chen Bai, obviously seeking Chen Bai's opinion.
"Have you ever asked your best friend what your relationship is with this person?"
"I asked, but Ding Wan didn't tell me, so there was nothing I could do."
Chen Bai nodded and then asked.
"and after?"
"Later... Later Ding Wan died. My best friend had always had a bad heart. One day I heard a colleague say that a girl was sent here because of myocardial infarction, but she still died after resuscitation. That girl was Ding Wan.
.But I feel that Ding Wan's death is not that simple. Although her heart disease is very serious, it will not be a big deal as long as she is not stimulated. But before I had time to ask the attending doctor, I received
That doll, and then the house caught fire."
Chen Bai and Xu Hai looked at each other. Since there is no evidence now, they might as well go find Yi Dingwan's attending doctor at the time and see what he said.
"Ding Wan? Oh! I remembered, you are talking about Dr. Qiao's best friend, right? In fact, the girl's bilateral pupils were already dilated when she was sent here. We also tried our best to rescue her, but in the end there was no success.
What result."
"Doctor, I would like to ask you if a heart disease like Ding Wan's is easily relapsed if it is suddenly stimulated?"
The doctor stood up and found Ding Wan's medical records from the cabinet behind him.
"Yes, Ding Wan's heart disease is a congenital heart disease. It may relapse if she is frightened or stimulated by loud sounds, but people like them will carry Suxiao Jiuxin Pills with them. There will be no such reason
Failure to take medication in time can lead to myocardial infarction.”
After coming out of the hospital, Chen Bai felt more and more that there was something wrong with this case, but he couldn't tell what the problem was yet.
"Xu Hai, I think we should go to Dr. Qiao first to learn more about her best friend Ding Wan!"
"Chen Bai, do you think there is something wrong with Ding Wan?"
Xu Hai was a little puzzled. Now this case is getting more and more confusing. Lei Zi and the others previously investigated the families of several victims of the wire murder case and found that they were basically not suspected of murder. This made Xu Hai more and more puzzled about what happened.
Four people killed Zhang Zhiyong.
"I don't know if there is anything wrong with Ding Wan, but now Ding Wan is the only clue that can lead to the investigation of this case."
Qiao Rui opened the door and found Xu Hai and Chen Bai standing outside. He couldn't help but asked with some doubts.
"What's wrong? Is there anything else?"
"Qiao Rui, you still have to tell us about your best friend now."
Although Qiao Rui was a little confused, he still let Chen Bai and Xu Hai in.
"Do you have anything else to ask?"
Although Qiao Rui was a little confused, he still spoke.
"She was a bar salesperson. She was a nightclub salesperson in the early 2000s. People who went to nightclubs at that time were very rich, so Ding Wan was also very rich at that time."
"Qiao Rui, that's not what I want to ask. What I want to ask is, do you know that the friends around Ding Wan are similar to Shen Qiang?"
Qiao Rui was a little confused. She couldn't understand what Xu Hai was talking about.
"Okay, who can understand what you say? Qiao Rui, the night Ding Wan said he wanted to borrow money from you, what do you think was the relationship between Ding Wan and that person?"
This question is very important because after investigating the social relationship between Ding Wan and Shen Qiang, it was found that there is basically no relationship between the two people.
"What's the relationship? If they are friends, they are definitely not. Ding Wan is surrounded by clients and colleagues. I can't tell what the relationship is between that man and Ding Wan, but I have a feeling that Ding Wan seems to be very afraid of that man.
man."
After coming out of the guest house, Xu Hai's head started to hurt more and more, and now he could no longer see the case clearly.
"Chen Bai, what should we do now?"
"have no idea!"
Chen Bai actually didn't know what to do now. He always felt that he was just one step away from finding the most critical clue in the case, but he just couldn't.
"Xu Hai, you should go back first! I want to stay by myself for a while!"
"good!"
Chen Bai walked aimlessly. He always felt that he seemed to have missed some details of the case, but he could not find this key detail.
"Consultant Chen, why are you here?"
"Ah! Let me come over and take a look!"
Chen Bai walked aimlessly, and when he looked up, he realized that he had actually arrived at the resort.
"Anything new at the scene over there in the cellar?"
"No, forensic doctor Zhao came to investigate the scene again after you took the body away. He is now in the cellar, but I think he found nothing."
Chen Bai nodded and walked towards the cellar. As soon as he reached the entrance of the cellar, he saw Zhao Pengcheng going up to the cellar.
"How's it going? Did you find anything?"
"No, in addition to the smell of corpses, there are a lot of rats in the cellar. Just now, a rat almost got into my clothes."
Chen Bai smiled. There were too many corpses in the cellar. After rotting and smelling, of course they would attract a lot of rats. Otherwise, the rats wouldn't go directly to the villa.
"Forensic Doctor Zhao, one of our little brothers here seems to be infected. Can you take a look at it for us?"
"I'm allergic, let me check!"
Zhao Pengcheng followed the young policeman to the hall. Chen Bai saw a person lying on the sofa in the hall. The person's exposed skin lying on the sofa had large areas of redness and swelling.
"Have you been to the cellar? There are too many bacteria in the cellar and it is easy to get fungal infection. It's okay. I have gentamicin here. I'll just give you an injection."
Zhao Pengcheng opened the medical box as he spoke, took out a tube of Qingda penicillin and placed it on the table.
"Wait a moment while I go to the car to get you iodophor."
"Comrade police officer, can you give my girlfriend a shot? She seems to be infected on her hands too."
Chen Xinxin rolled up her clothes as she spoke, and Chen Bai saw that Chen Xinxin's arms were also red and swollen.
"Well, if anyone else is allergic, I'll take care of it for you."
When Zhao Pengcheng came back, he had two syringes and a bottle of iodine in his hands.
"I know you want to help, but there are too many bacteria in that cellar. It's best if you don't go down there."
Zhao Pengcheng was preparing iodophor, and at this time a man walked out of the crowd. The man picked up the penicillin in his right hand, flicked it a few times with his index finger, and opened the bottle.
"Thank you!"
Zhao Pengcheng didn't say much, but Chen Bai asked with some confusion.
"you are a doctor?"
"Previously!"
Chen Bai recognized that the man lived opposite his villa. The man greeted him at the door the day he first arrived.
"Okay, I'll give you a penicillin injection, and you'll be fine after a while."
"By the way, I'm going to see Wang Qingshan's office."
Only then did Chen Bai remember what he was doing here. Because he wanted to know the relationship between Wang Qingshan and Zhang Zhiyong, Chen Bai decided to go to Wang Qingshan's office to have a look.
"You go ahead! Leave this to me!"
But to Chen Bai's disappointment, he searched Wang Qingshan's office and couldn't find what he was looking for.
"Hello? What did you say? Okay, I'll be right back."
Chen Bai returned to the police station and hurried into the office. At this time, Song Anchun was sitting behind the desk. The doll found at the crime scene had been dismantled into pieces.
"What did you just say you found?"
"Chen Bai, look at this!"
Song Anchun held a bunch of dark things in his hand. Chen Bai was a little surprised because these things would be almost unknown to people who were not a little older.
"Is this the plastic strap inside the tape? How did you find it?"
Song Anchun put the things on the table and said proudly.
"I have been thinking since I got up today, why did the murderer send this doll to those people specifically? Although I can now confirm that the hair of the doll is indeed human hair, is the murderer's purpose really that simple?
So, I took the doll apart and decided to study it further, and unexpectedly I discovered this."
Chen Bai looked at the plastic strap on the table and immediately called Xu Hai.
"Xu Hai, does your police station have radios and tapes?"
"What do you want this for?"
Xu Hai was a little confused. Chen Bai had no choice but to explain Song Anchun's findings to Xu Hai.
"No problem, I'll have Lei Zi prepare it for you right away."
Things were quickly prepared, but Lei Zi held the recorder and tape and asked with some doubts.
"Consultant Chen, the things are prepared for you, but what are you going to do with them? How are you going to get them entangled?"
"Look at me!"
Chen Bai found a pencil, first took out the tape from the old tape, then took it apart and wound the tape in bit by bit.
"Can this thing be done like this?"
Lei Zi was a little surprised, but Chen Bai just smiled and said.
"It's nothing, this was normal when we were kids."
After the tape was finished, Chen Bai turned on the tape recorder. After a burst of tingling sounds, a man's voice came from inside.
"Is this our goal?"
"Yes, this is..."
After the man spoke, there was a woman, but I don't know if the tape was damaged or for some other reason, but there was no sound after that.
"Did you just dismantle a doll?"
"Yes, I dismantled the doll I found at Shen Qiang's house."
Chen Bai frowned. Since this thing can be hidden inside the doll, it means it must be very important. But now this thing can't hear anything. The only thing that can be heard is the conversation between a man and a woman.
"Take apart all the remaining dolls and see what else is inside."
"good!"
Song Anchun took a scalpel and took apart the remaining dolls one by one. Finally, he found a flash memory card inside the head of the doll found at Qiao Rui's house.
"Hurry up and see what this is!"
Chen Bai took out his computer, inserted the flash memory card and the screen slowly appeared.
"Is this... a candid photo?"
The scene in the video should be a KTV private room. The video was obviously secretly filmed, but Chen Bai and the other three were shocked when they saw the people in the video.
"Are these Shen Qiang and Ding Wan?"
After the two of them sat down, Ding Wan took out a bulging envelope from his bag.
"This is your hard-earned money, and I will give you another 100,000 yuan after the project is completed."
After Ding Wan finished speaking, Shen Qiang picked up the envelope, looked at it, smiled and said.
"No problem, isn't it just to scare a girl? This kind of thing is easy for us. We just don't know what you want to achieve."
"I just hope this woman can disappear from my sight and never bother me again."
Ding Wan said and took out a photo. Chen Bai quickly pressed pause with his eyes and hands. Although the picture was a bit blurry, Chen Bai quickly took another computer to copy the video clips and sharpened them.
"This is...Xu Jiaying?"
When Chen Bai restored the person in the photo, he was stunned. Is it possible that there is still a relationship between Ding Wan and Xu Jiaying?
"who is this?"
Song Anchun didn't know who the girl in the photo was because she had never seen the wire murder case file.
"Leizi, go check it out!"
"good!"
After Lei Zi left, Chen Bai explained to Song Anchun who the girl in the photo was.
"You mean to say that the first girl Zhang Zhiyong and the three killed at that time actually had a purpose?"
Chen Bai took out a cigarette, lit it and said.
"We can see from the wire murder case files that Zhang Zhiyong and the other three were looking for women in their twenties who were alone, kidnapped, raped, and finally killed them. But generally serial killers commit crimes alone, because each serial killer They all have their own goals and symbols. The three of them have the same hobbies and can come together to kill people in the same way. This probability is lower than the probability of being struck by lightning. Ding Wan said in the video that it was scary. Looking at Xu Jiaying, I think this cannot include killing. Although Ding Wan said that this woman should never appear in my sight, it is very possible that for some reason at that time, Zhang Zhiyong and the other three killed Xu Jiaying. From that time on, the three of them found this kind of thing very exciting, so they committed more and more crimes. Including later, they kidnapped Shen Man and extorted money."
After Chen Bai finished speaking, Song Anchun nodded. Perhaps this is the only explanation that makes sense now.
"If that's the case, then it's understandable what Qiao Rui said that day when she saw Ding Wan and Shen Qiang after Ding Wan asked her to borrow money. Shen Qiang could use this video to blackmail Ding Wan and make Ding Wan unable to do so. Don’t give in.”
Of course, all this is just speculation by the two of them. As for what the truth is, they still need to investigate further.
"Consultant Chen, I found out the relationship between Ding Wan and Xu Jiaying that you asked me to check. Xu Jiaying used to work with Ding Wan in a nightclub before her death, but I don't know why Xu Jiaying suddenly resigned, and Xu Jiaying was killed not long after."
Chen Bai nodded. The two of them worked in the same place, so there was probably a conflict. Ding Wan impulsively asked Zhang Zhiyong to teach Xu Jiaying a lesson. Later, Xu Jiaying died. Although these were investigated, the relationship between the two cases was still unclear. The progress is not helpful. In fact, what Chen Bai wants to investigate most now is the family members of the victims of the previous wire murder case, but none of those people are willing to cooperate, and Chen Bai has nothing to do.
