The phone hung up without any additional prompts.

Everyone can't wait, no matter what Cao Yunpeng said is true, or he deliberately said a fake address to trick them into going and giving him time to escape, they all have to go on a trip.

Ding Xiaoqian sat quietly in the back of the car, a little drowsy. She closed her eyes, let Xu Ziqian put her arm around her shoulders and let her lean on his shoulder, and said in a small but firm voice: "Cao Yunpeng didn't lie to us, I have a bad premonition, and the picture we see after that will not be too good." ”

Xu Ziqian also has this idea. Although Cao Yunpeng admitted on the phone that the six lives were all lost in his hands, if the specific circumstances of the crime and the motive for the crime are not clarified, it is not enough to solve the confusion in people's hearts. In addition, all the analysis was conducted by Ding Xiaoqian on the phenomenon of insufficient evidence, and there was no direct evidence to prove that Cao Yunpeng was the murderer, even if he knew that he was the murderer, he would not be able to accuse him due to insufficient evidence.

The place Cao Yunpeng mentioned is a place that is not too close and not too far, and it takes about half an hour to drive from the city center, and if Cao Yunpeng usually rides a bicycle, it will take a little longer.

Sure enough, as Cao Yunpeng said, there was a private house at the end of the dirt road after turning the jade road. The large open space at the entrance was neatly cleaned up.

For fear that Cao Yunpeng would play some tricks, the Xiaoshan City Police Department even sent special police, approaching the house lightly all the way, blocking Xu Ziqian and others behind.

The door was slammed open, and several guns were pointed at the house, and then a person's shout was heard: "Cao Yunpeng is dead!" ”

Ding Xiaoqian immediately ran over, stumbling and almost falling. Xu Ziqian moved faster to support her, pulled her forward, and rushed into the house almost instantly.

The room was also very tidy, Cao Yunpeng sat on the ground leaning on a chair, he had stopped breathing, but his eyes were wide open.

"The scene is cordoned off, and others are not allowed to enter, so as to avoid damaging the footprint." Xu Ziqian hurriedly prevented more people from entering the room. He has encountered this situation before, some stolen families were originally very good at solving the case, but because the police entered the room first after receiving the report, they took some auxiliary police to check whether there was any property lost, and finally the footprints in the house were mixed, which added great difficulty to solving the case.

Cao Yunpeng claimed that he was a murderer, but Xu Ziqian and Ding Xiaoqian saw at a glance that he was dead, and the humerus, ulna and radius of the entire left arm were removed by a boning knife, and only the flesh on the palm and arm was connected to the shoulder blade. They have reason to suspect that Cao Yunpeng is just a scapegoat, and it is likely that he was coerced to admit that he was the murderer, but the real murderer was someone else.

There were many books in the room, especially on chemistry and medicine, as well as many chemical refining tools, dimethylmethanol and some anesthetics, and on the right hand of Cao Yunpeng's corpse, a boning knife with blood stains was thrown on the ground. To the right of the boning knife, a violin made of a special material catches everyone's attention. When everyone looked at the violin intently, they couldn't help but take a breath of cold air.

The whole violin was actually made of human bones, and there was blood dripping from the last bowstring.

Xu Ziqian motioned for his colleagues in the technical department to come in and extract evidence, carefully bypassing Cao Yunpeng's body and coming to the wall where he looked directly at the wall.

The wall is pasted with photos of the previous six victims and their usual preferences and habits, etc., and he is vigorous and powerful, and his pen is turned around, and he has obviously put in great effort.

All physical evidence has been retrieved, and the scene is tightly cordoned.

After two days and one night of overtime, the examination report of all the evidence was presented.

Cao Yunpeng died of excessive blood loss, and there was no zài dimethyl methyl ketone in his body and mouth. However, a large amount of ingested anesthetic was detected in his left arm, and from the analysis of the direction of deboning and the use of force, the bone of Cao Yunpeng's left arm was removed by himself.

The result is shocking and even more incredible.

The bones on the human violin in the extracted evidence report were Hu Tingting, Dong Wanxing and Zhou Tao, and the bowstring was Cao Yunpeng's. There were only Cao Yunpeng's fingerprints on the boning knife of the murder weapon, and there were no other traces. The residues in the chemical refining products in the house were extracted, and dimethylmethanol and dimethyl methyl ketone after extraction were found. As for the dilapidated bicycle parked outside the house, it had already been pushed back, and fibrous tissue was found from it, which was analyzed by Hu Tingting.

The rest are some books on chemistry and medicine, the key points of which have been outlined, and the focus of Cao Yunpeng's research can be found in a light way.

Cao Yunpeng committed suicide in fear of sin, but why did he make a human bone instrument, and why did he choose these people to start? And why did he deliberately cut off his hand bones when he committed suicide in fear of sin to complete the human bone violin.

originally thought that the case had been solved, but there were still a lot of doubts that had not been clarified. Ding Xiaoqian didn't even dare to swallow hard because of his sore throat, and he lost a lot of weight in a few days, and his originally small round face became a sharp melon seed face.

Xu Ziqian looked distressed and tried his best, but this girl struggled to take medicine, and her mouth was still tricky when she ate, and he had already changed his tricks to make up for her body, but he was still visibly losing weight.

Xu Ziqian really had no choice, and he couldn't sit idly by, so he simply found the director of the Xiaoshan City Branch and applied to return to the team.

As soon as Ding Xiaoqian heard the news, he immediately became anxious, and he couldn't calm down.

"The case is not over yet, how can we go back?"

"Are you going to let me see you lose weight day by day until you lose weight?" Xu Ziqian replied even more domineeringly.

Ding Yijin's craftsmanship has always been Ding Xiaoqian's favorite, and this time, even if he risks being hacked to death by the Ding brothers, he will send Ding Xiaoqian back to Ding's house to make up for his body.

"It's nothing to be thinner." Ding Xiaoqian touched his cheeks, and he felt that he had lost weight.

Xu Ziqian glanced at Ding Xiaoqian, who didn't have much meat, and said in a sullen voice: "It's too thin to have children." ”

"Really?" Ding Xiaoqian immediately believed it.

Xu Ziqian nodded very sincerely.

Ding Xiaoqian was anxious: "Then hurry up and finish this case, let's go back to Jiangbei, I want the second brother to make me something delicious, eat a little more and make up for it." ”

Xu Ziqian's breath was suffocated, and she regarded it as such an urgent matter, and she could only rank behind the case to solve it.

Just when Xu Ziqian was hesitating whether to simply knock Ding Xiaoqian unconscious and take him back to Jiangbei City to hand over to the Ding brothers, there was finally the greatest progress here.

A CD was found in Cao Yunpeng's house, in which Cao Yunpeng described all the motives and processes of the crime. Include...... His background.

Xu Ziqian was immediately shocked, and he was finally able to complete the task and return to the team. Participated in the work to solve countless cases, this is the first time that he is so eager to rush back, saying that he doesn't want to stay here anymore.

The lights in the conference room dimmed, the projector lit up, and Cao Yunpeng appeared on the screen, with the house he lived in in the background, next to a human bone violin with a missing bowstring, and the video recording time showed a day ago.

"Hello everyone, I'm Cao Yunpeng. I'm sure you'll be familiar with my name when you see this CD, but you can only hear about the crimes I have committed.

I was born into the poorest family in Jingshan District, the poorest area in Xiaoshan City, and my mother and I lived together, and since I was a child, I didn't know who my father was. Every time I asked about my mother, she would beat me up and scold her, and she would never allow me to mention my father.

When I was a child, I thought I was a fatherless child. Slowly, I grew up, and like children of the same age, I started to go to school, but I had to be called a wild child every day. I didn't dare to tell my mother that I had to chase and beat the children who scolded me every day, but they beat me harder. Whenever I came home with all kinds of injuries, my mother would hold me and cry, and then beat me again.

The word father has always been taboo in my family. Until one day, I realized that it was not that I did not have a father, but that my father was a beast. He raped my mother, and I am the evidence of his crimes......"
