Xu Ziqian waited until the discussion gradually disappeared before he slowly spoke: "What you said is not correct, don't ignore the key to this, believe the murderer and take dimethylmethyl ketone, a liquid that can suffocate to death." Of course, the taste of dimethyl methyl ketone is light and fragrant, and it will not arouse the vigilance of ordinary people, but if a stranger suddenly gives you a glass of water, just ask, will you drink it? ”

His eyes glanced at everyone, and he slowly spoke: "What you are talking about sending couriers, collecting electricity bills, and checking water meters, these people can only let the victim open the door or go downstairs at most, and cannot make the victim trust the murderer and drink the water sent by the murderer." Even taxi drivers can only get away with the victims, and when the victims find that their location is different from the destination they want to reach, it will immediately arouse the victim's vigilance. Therefore, to sum up, the perpetrators can only be people who are familiar with these people. ”

He didn't give others a chance to think, and continued, and his speed gradually increased: "Ding Xiaoqian has already said it before the acquaintance between Cao Yunpeng and the victim, so I won't describe it here. Next, let's talk about the murderer's way of throwing the body. After killing the victim, the murderer used a bicycle to throw the body, he tied himself to the victim's body with a thick rope, put the deceased on the back seat of the bicycle with a back style, rode to the place where the body was dumped, and then untied it, and dragged the victim's body to the designated place to throw the body. Such a conclusion comes from the autopsy report of Hu Tingting and Zhou Tao, both of them have relatively inconspicuous strangulation marks from the back of their bodies to both sides of their waists, and at the same time, Hu Tingting's shoe tips have a certain degree of wear and tear, Zhou Tao because of his relatively tall stature, his entire leg is dragged on the ground, and the wear area of the guide zhì is very large. Later, the heels of the two men rubbed again, and there were obvious objects in the surrounding environment on the back of the trouser legs, which were caused by the murderer when he dragged the corpse. ”

He sighed, his eyes becoming a little confused: "The only thing I don't know now is his motive for killing. I can still think of why he committed the crime in the previous bone throwing case, but in the next three bone removal cases, it is not clear what his motive was. It seems that this matter can only be clarified after finding Cao Yunpeng. ”

This is not only Xu Ziqian's doubts, but also everyone's doubts. Especially Ding Xiaoqian, who has been in contact with Cao Yunpeng, if it weren't for Cao Yunpeng's exposure in Zhou Tao's case, she would not have linked the real murderer with this sunny and cheerful boy at all.

The most unacceptable of this result was the president of Sun Yat-sen University, who went from disbelief to shock, and finally had to accept the evidence, and had collapsed in her chair.

The arrest warrant was quickly applied, and the director of the sub-bureau personally led a team to Sun Yat-sen University to arrest Cao Yunpeng.

Ding Xiaoqian was unwell, but he insisted on going with him. Just like Xu Ziqian thought, she also wanted to find out what Cao Yunpeng's motive for killing was. There is nothing but hatred in his heart that has not been accomplished!

The convoy stopped at the gate of Sun Yat-sen University, and in order to avoid startling the grass and snakes, it didn't even turn on the police lights, and naturally the siren didn't dare to sound.

But Sun Yat-sen University searched all corners, but failed to find Cao Yunpeng's figure, and asked Cao Yunpeng's roommate, he didn't have any work outside today, and he would stay in the dormitory most of the time on weekdays.

The police station conducted a thorough search of Cao Yunpeng's dormitory, and although the classmates in the same dormitory did not know what Cao Yunpeng had committed, they knew in their hearts that Cao Yunpeng must have done something illegal, and the matter must be not small, so he would work so hard.

When Cao Yunpeng was almost ready for everything, Xu Ziqian unexpectedly received a call from Cao Yunpeng.

"Cao Yunpeng, where are you?" Xu Ziqian asked straight to the point, his voice was as usual, and he couldn't hear any strange feelings.

"Captain Xu, I know you're looking for me, don't bother. I can know that you are looking for me, and I will hide obediently and will not let you find me. Cao Yunpeng's tone was full of confidence.

"Cao Yunpeng, you have to think about it carefully, if you can turn yourself in, we may be able to fight for leniency for you." The director of the sub-bureau snatched the phone in Xu Ziqian's hand, and at this time, he couldn't care about Xu Ziqian's identity as a detective, and the arrest of Cao Yunpeng and the end of the two unsafe cases were the biggest and most important things at the moment. The city bureau has repeatedly issued orders to seize the time, and now that the end of the year is approaching, it will be bad if this Cao Yunpeng has a very strong anti-reconnaissance ability, and wants to hide in the deep mountains and old forests for a few months and turn this case into a sinking case.

Cao Yunpeng scoffed at the words of the director of the sub-bureau: "Six lives, the result of leniency is to kill me with one shot." Oh no, maybe I'll be hated by thousands of people, scolded by thousands of people, and maybe I have to take a few more shots when one shot can be over. He smiled hehehe, but his laughter was very sincere: "No matter who you are, don't persuade me, I also know that I will definitely not have any leniency, I just want to say a few words to Officer Ding." ”

The director of the sub-bureau looked at Ding Xiaoqian with an inquiring eye, Xu Ziqian turned on the speakerphone when he answered the phone before, and Cao Yunpeng's voice was heard clearly by everyone present.

Xu Ziqian nodded towards Ding Xiaoqian, and Ding Xiaoqian hoarsely spoke: "I'm Ding Xiaoqian." ”

Cao Yunpeng exclaimed: "Officer Ding......"

"Yes."

"I wonder, when did you start guessing me? The three people in front of me are innocent, let's not talk about them, let's just talk about the people in the back, I have been planning for months, including your appearance is in my step-by-step plan, I can even use you to create alibi, how did you guess that it was me? ”

Cao Yunpeng thought that his plan was perfect, otherwise it would not have been so long since the previous three consecutive bone throwing cases had happened, and no one could find clues from them.

Ding Xiaoqian held the rock sugar pear water, took a sip lightly, moistened his lips and said, "Do you still remember that on the day Zhou Tao was killed, we accompanied Hu Tingting's parents back to school to sort out Hu Tingting's relics?" ”

Cao Yunpeng's voice was smooth, neither the bloodlust after the killing, nor the panic after his true identity was discovered. Just like chatting usually, he will laugh a few times when he talks about ridiculous places, and at this moment he is full of desire to learn: "I remember, we met, and you also asked me what I do in the Loving Nursing Home. ”

"Yes." Ding Xiaoqian replied: "According to Cheng Dù under the rain, you are wearing a raincoat, even if you get wet, it should only be wet to the calf area." But your buttocks are tightly attached to the raincoat, which means that your buttocks are wet, so they will fit the raincoat. At the time, I was only slightly skeptical about what kind of work would make a person's buttocks wet under a raincoat wrap, and your answer caught my attention, you didn't go out, you were just doing something indoors in the nursing home, and you didn't have the opportunity to go outside at all. But not only are your buttocks wet, but even the toes of your shoes are covered in mud, which means you've been outdoors for a long time.

It wasn't until the report of Zhou Tao's murder came that I saw the dirt at the scene, and it was the same kind as the one hanging on the tip of your shoes, marble powder. In addition to the place where the stone is processed, the marble powder is only available in the mountain mine, and you have an abnormal situation, which coincides with the scene of the murder, so I suspect you. ”

"You're smart." Cao Yunpeng praised from the bottom of his heart. "From the first time I saw you, I thought you were not simple, you don't look so attention-grabbing, but as long as you look at people, it will make people panic from the heart."

Ding Xiaoqian was silent, not knowing if he should thank Cao Yunpeng for his praise.

"I know I'm sinful, but now that my wish is about to be fulfilled, there's nothing to be nostalgic about." His voice suddenly became muffled, as if he was enduring some kind of pain, and only his heavy wheezing voice could be heard on the phone: "Follow the Emerald Road until the end, then turn right into the dirt road, and then go to the end, and you will see a private house." ”

His voice gradually lowered: "Officer Ding, this is a special benefit for you. If you can get here sooner, I'll tell you myself, why should I kill them......"
