"I can break it." I said to Xie Jing.

Xie Jing obviously didn't believe what I said, he asked me how I was going to solve the case, I didn't answer him, and took Xu Yi into Wang Xin's office. Xie Jing did not hide the provocation in his words at all, and kept shouting behind me. In fact, Xie Jing was very polite to me at first, and we had a disagreement over the confessions of Zhou Guang and his wife.

The confession of a criminal suspect is the "king of evidence" and has a very high probative effect in many pieces of evidence, and it is precisely for this reason that Xie Jing advocates that Zhou Guang be directly transferred to the public prosecution as the main suspect, Sun Zaiyun as the instigator, and Zhou Guang's wife as an accomplice.

Compared to me, Xie Jing already has a goal, so he can collect evidence much faster. Mr. and Mrs. Zhou have already made a guilty plea, and although there are many doubts, the court is likely to issue a guilty verdict if it were combined with the book that records the method of peeling.

In particular, Zhou Guang and his wife were involved with the organization established by Sun Zaiyun, and it was during the period of the cult's crackdown and the pressure of media and public opinion in Guangdong City, so if Zhou Guang and his wife were prosecuted, it was very unlikely that they would want to get away with the crime.

The file bag in his hand contained the final autopsy report of the corpse. On the third day after the incident, the final autopsy report of the body was finally released, and the people in the police station also held a meeting on the report. On the surface of Zhou Xiaoruo's body, some imperceptible chemicals were found, and the people of the identification department repeatedly extracted and tested them, and finally extracted some substances containing potassium and sulfur.

The forensic department finally found out why the body was so badly decomposed in such a short period of time. Potassium and sulfur are the main elements in two chemicals, potassium permanganate and concentrated sulfuric acid, which are mixed together and have high levels of corrosiveness.

The people of the identification department have done a comparative test with animal carcasses, after peeling off the skin of the animal carcass, coating a layer of potassium permanganate and concentrated sulfuric acid on the surface of the carcass, it will not take a few hours for the surface of the carcass to be corroded, if it is wrapped with several layers of plastic paper and exposed to the sun, it can indeed create a high degree of decay on the surface of the carcass.

However, at first, the forensic department did not find any residue of these two chemicals on the surface of the corpse, and even two days later, only potassium and sulfur were found. Therefore, the forensic department speculated that the murderer had chemically neutralized the two concentrated liquids and washed them with water after partially corroding the body.

After the surface of the corpse decomposes, it is indeed easier to dry by hanging on the hillside for thirty hours in the wind.

After reaching this conclusion, Xie Jing immediately interrogated Zhou Guang and his wife again, but Xie Jing's method was still induced interrogation, and as I expected, Zhou Guang and his wife confessed. When asked why they didn't say it before, their reason was that they felt that everyone had been killed, and there was no need to say more.

Because Xie Jing's interrogation method was inappropriate, I had another big fight with him that day, so until the last day of the deadline to solve the case, our tension reached its peak.

In the past few days, Xu Yi and I have paid close attention to Xie Jing's every move, but we found that Xie Jing actually has no problem, he has been with Wang Xin for more than 20 years, and he just doesn't want Wang Xin to take the blame and resign, so he is in such a hurry to solve the case. Wang Xin didn't interfere either, as soon as we entered the office, he took the kettle to water the plants in the office as always.

Since smoking a cigarette that day, Wang Xin has picked up the smoking addiction he has quit for many years, and he will light a cigarette whenever he is free, and the trash can in the office is full of leftover cigarette butts and ashes he has smoked in the past few days. Jiang Jun's physique is very good, and he was able to be discharged from the hospital within two days of being injured, except that his movements cannot be too big, he does not look like he has been injured at all.

After midnight tonight, Wang Xin's "military order" will expire, and if I can't solve the case, he will immediately take the blame and resign. I'm not worried about this, everyone has everyone's decision, if he wants to resign, no one will keep him, what I'm worried about is that Xie Jing will end the investigation of Zhou Guang as a suspect, which will be troublesome.

Most of the people in the entire police station were on Xie Jing's side, and only a small number supported my decision, and Jiang Jun was one of them. He was in a hurry, we were sitting in the office, Jiang Jun was pacing back and forth, he was more anxious than any of us. Finally, when he saw me sitting motionless, he couldn't help it.

"Professor Li, what should I do next, today is the last day!" Jiang Jun moved so much that he touched the wound on his back, and he grinned with his teeth, but he didn't care about the pain, and stared straight at me, waiting for me to answer him.

"Wait." I answered Jiang Jun a word, Jiang Jun immediately asked me what I was waiting for, I didn't answer him, picked up the tea on the table and took a sip. In this case, the clues of several suspicious points have been broken, and if it weren't for the fact that I suddenly discovered a strange phenomenon last night, I don't think I was sure that I could solve this case.

I've sent someone to check what I want to check, and now all I'm going to do is wait. I don't say it, not because I deliberately sell it, but because this matter is very important, and I am not suitable to say it until I am sure.

Jiang Jun was very anxious, and he ran to Wang Xin again, who was sitting quietly at his desk reading a book at the moment.

"Dad." Jiang Jun is Wang Xin's adopted son, but Jiang Jun has always called him that.

Wang Xin raised his head with a smile and asked him what was wrong. There is a window behind Wang Xin, and the sunlight at nine o'clock in the morning is neither strong nor weak, and the sunlight spills through the branches into the windowsill, leaving a patch on the desk.

A few days ago, Jiang Jun's mentality was quite good, but on the last day of the deadline for solving the case, Jiang Jun finally became anxious. Wang Xin's appearance, he couldn't understand it at all. He asked anxiously, "Dad, do you have any plans?" ”

Wang Xin closed the book and asked Jiang Jun: "What can I do?" ”

Jiang Jun: "Are you really not going to care?" ”

Wang Xin nodded, he said that he handed over the case to us at the beginning, and he said that he would not take care of it. Jiang Jun wanted to say something more, but Wang Xin interrupted him. Wang Xin is still very calm, he said that even if he intervened at the beginning, he would not be able to solve this case, and among the people he knew, only I might have solved this case.

Speaking of this, Wang Xin stretched out his hand and pointed at me.

Jiang Jun looked at his fingertips, and from Jiang Jun's eyes, I couldn't see his firmness towards me at the beginning. I don't mind, I've seen a lot of these looks.

"Why, don't you believe Professor Li?" Wang Xin asked.

Wang Xin's question also made me interested. Since Jiang Jun rescued me, my good impression of him has been even greater, as Wang Xin said, Jiang Jun's skills are very good, especially in this period when Xu Yi needs protection, he has helped me a lot. It is undeniable that Jiang Jun has other advantages and disadvantages, but I think this person, as long as he is willing to work hard, one day he will be able to achieve great achievements in this system.

Wang Xin and I both set our eyes on Jiang Jun's body, and on the first day I met Jiang Jun, he excitedly shook my hand and said that he was my admirer.

Jiang Jun lowered his head and thought carefully, he seemed to hesitate, but in the end, firmness returned to his eyes, he walked up to me and told me very respectfully that he believed me.

"Jiang Jun, if I ask you to resign, are you willing?" Wang Xin said suddenly.

Jiang Jun was a little dazed, he scratched his head, and said that if he didn't work as a policeman, he wouldn't know what to do. The police station is a place where he wakes up every day and thinks of it, this can no longer be said to be a habit, but a kind of branding, Jiang Jun said that he has no way to imagine the scene of his resignation, he has to work until he is old and has no strength.

Jiang Jun's remarks reminded me of my own career in the police academy, where the word "police" was the ideal of all people, whether it was those friends who became police officers, or those who embarked on academic practice and research like me, they were actually doing the same thing.

"What if it's like me." I said to Jiang Jun.

Jiang Jun was stunned, he was about to ask, the person I sent out finally came back. I immediately stood up and walked to the door to take a thick copy of information from the detective's hand, which was what I had been waiting for.
