After a quick glance at the autopsy report and the identification report of the traces at the scene, my heart sank. Jiang Jun and Xu Yi were both looking at me nervously. Unlike the dark interrogation rooms of several police stations before, the interrogation room of the Zhushi Police Station is bright and has a lot of space, but it is such a huge interrogation room, and the atmosphere at the moment is even more depressing.

Ma Tao and I didn't speak for a long time, Jiang Jun was anxious, his two hands were already handcuffed, he wanted to take the appraisal report in my hand, I immediately closed the information and put it on my lap. I told Jiang Jun not to worry, as long as he answered my questions well.

Jiang Jun trusted me and sat back quietly, but compared to just now, he was much more anxious. Ma Tao's expressions and I had already made Jiang Jun vaguely guess something, his two handcuffed hands were folded together, and the emotional instability made his hands tremble slightly.

I looked at Ma Tao and motioned to him if I could interrogate, Ma Tao thought about it and said that the interrogation would be conducted in twenty minutes, let's go out first. Ma Tao led us out of the interrogation room, and after closing the door of the interrogation room, we heard the sound of Jiang Jun pounding the table.

After coming out, Ma Tao immediately went to prepare for a new round of interrogation, and Xu Yi and I stood in the corridor aisle and waited. The sun is shining, but our mood is the exact opposite of the sunshine. Xu Yi asked me what the appraisal report said, and I sighed and told Xu Yi all the appraisal results.

After Xu Yi heard this, she was also taken aback, and then, the gloomy cloud climbed up her eyebrows.

The results of the appraisal were very unfavorable to Jiang Jun. The cause of Qian Er's death has been determined to be a wound on the chest, and after wound comparison and bloodstain identification, the dagger has also been determined to be a tool for committing the crime. Qian Er was stabbed to death by someone with that dagger more than a dozen times, and the dagger stabbed into Qian Er's heart, causing massive bleeding in the atrium.

Qian Er's body also had a wound, and that was the palm of his left hand. The autopsy report said that the scratches on the palms were disorganized and that each cut was very deep. Seeing this, I couldn't help but wonder what the murderer's purpose was.

As for the time of death, it has also been preliminarily determined to be around zero o'clock, and there are errors in the identification and inference of the time of death, but this is highly consistent with the time when we heard the screams.

There were no fingerprints found on the dagger, except for Qian Er's bloodstains, which were the DNA traces of Jiang Jun on the hilt, when catching snakes, Qian Er gave us cotton gloves, and the lack of fingerprints on the dagger seemed to be in the past. This evidence is undoubtedly a huge blow to Jiang Jun, and coupled with the fact that Jiang Jun did not have an alibi, Jiang Jun's suspicion is even greater. The blood stains on Jiang Jun's cuffs have coagulated, and due to the fact that the weather is hot and the blood stains are only a little sporadic and the reason why the blood stains are only a little sporadic is difficult to accurately determine.

If further appraisal reports and post-mortem reports do not reveal any more favorable clues to Jiang Jun, the public security organs can even directly terminate the investigation and hand Jiang Jun over to the procuratorate for public prosecution.

I frowned, and when I was thinking carefully, a criminal police officer came to me, and he said that Ma Tao invited me and Xu Yi to go to the police office. After arriving at the police officer's office, I understood Ma Tao's thoughts, Ma Tao thought that our relationship with Jiang Jun was extraordinary, so Xu Yi and I could not directly participate in the interrogation of Jiang Jun, so as not to affect the outcome of the interrogation.

However, Ma Tao allowed me to give advice on the content of the interrogation to the public security organs as an investigation expert, and the criminal police would interrogate the questions I left behind one by one during the interrogation, and Ma Tao would also record the entire interrogation process. Ma Tao is very thoughtful, human life is at stake, and he can only follow the procedure. Ma Tao's meaning indicated that the police department officially invited me to assist in the investigation of the case, but due to the sensitivity of my identity, my authority must be much smaller than that of the previous cases.

Ma Tao shook my hand apologetically, saying that he was also routine, and that in addition to giving an explanation to the deceased, he also had to give Wang Xin an explanation.

I spent a few minutes thinking about a few very critical questions, the criminal police followed Ma Tao into the interrogation room after the record, Xu Yi and I sat in the police office and waited, at first we could wait patiently, but seeing that Ma Tao and they did not come out for a long time, Xu Yi and I were anxious.

It was 10 o'clock in the afternoon, the weather was extremely hot, there were many people in the police office, and the four ceiling fans that were slowly swaying overhead did not work at all. We waited for more than 40 minutes, and during this time, we were sweating profusely, and Ma Tao said that he had notified Wang Xin in accordance with the regulations on arrest.

But Wang Xin didn't call me, and after thinking about it, I decided to give Wang Xin a call. Wang Xin quickly picked it up, to my surprise, Wang Xin was not in a hurry, I asked him if he would come to Zhushi, and he said no. I apologized to Wang Xin, but Wang Xin told me lightly that Jiang Jun would not kill.

"Professor Li, I know Jiang Jun best, he can't kill people. I have entrusted Jiang Jun to you, and I am sure that you will definitely help him clear his suspicions. "Wang Xin's calmness is almost beyond my comprehension.

Talking to Wang Xin several times, I could feel his guilt and love for Jiang Jun, the adopted son, from his words. Wang Xin didn't say much to me, just repeated that he believed me and hung up the phone after waiting for my good news.

After putting away the mobile phone, Xu Yi asked about the situation, Xu Yi had no way to understand Wang Xin at all, Guangdong City and Zhuhai City are not too far apart, even if Wang Xin firmly believes that Jiang Jun did not kill anyone, he also believes that I will help Jiang Jun clear his suspicion, and he should not even refuse to make such a trip.

Just as Xu Yi was complaining, Ma Tao came back with someone, and he took Xu Yi and me to his own office. Ma Tao told me that the interrogation transcript and audio recording had been prepared, and Jiang Jun's emotions were out of control for a while, and after the interrogation was over, he was sent to the detention cell.

Ma Tao handed me a few pages of paper, which were a backup of the interrogation transcript, with Jiang Jun's fingerprints and signature. After Ma Tao played the audio recording of the interrogation, I carefully compared the words on the interrogation transcript and listened.

At the beginning of the interrogation, Jiang Jun was informed of the relevant provisions of the Criminal Procedure Law and Jiang Jun's rights and obligations, and Jiang Jun was very cooperative, so the interrogation immediately entered a critical point. The criminal police got straight to the point and asked Jiang Jun if he had killed anyone, which was a fork in the road, and whether Jiang Jun admitted it or not determined the direction of the interrogation.

Jiang Jun naturally denied it, so the criminal police then asked Jiang Jun about the purpose of going to the village and the mass grave, Jiang Jun was quite calm, and he could answer the questions asked by the criminal police clearly and truthfully. But when asked where Jiang Jun had gone during the time when he was not with us, Jiang Jun could not answer.

Jiang Jun said that he didn't know where he had gone, that the field behind the mass grave was too big, and that it was dark at night, so he ran all the way forward, making a big circle before returning along the way.

Next, the detective asked another question, and this is the question I am going to ask. After Jiang Jun ran away with Qian Er, I made a total of three phone calls to Jiang Jun, the first time was about 20 minutes after Jiang Jun left, and Jiang Jun answered the phone that time. The second call was made after we waited for a while, and the last call was made after we heard the screams, but Jiang Jun did not answer the last two calls.

This is a suspicious point, although I believe that Jiang Jun will not kill anyone, but all the doubts in the case must be solved clearly, so that it is possible to clear Jiang Jun's suspicion and find out the real murderer.

Jiang Jun replied that he answered the phone because he was just about to call us, and because the mobile phone was turned to vibrate and the clothes on his body were very thick, he did not notice the last two calls. After Jiang Jun was arrested, his mobile phone was also confiscated, and the criminal police found that Jiang Jun's mobile phone was not set to vibrate at all.

In this regard, Jiang Jun's explanation was that he really couldn't find Qian Er, and when he was about to return, he remembered to call us again, and he only found out at that time that we had called him two more times, and he casually turned his mobile phone to ring, and was about to call us, but he happened to hear us shouting at him, so he didn't call, but answered us with his throat pulled.
