Blood remained on the steps, only a few bits of it, and the staircase was where the shirt had been lying quietly. The steps were very high, and the stagnant water on the ground did not overflow the steps, so the few bits of blood were well preserved. The blood stains had already coagulated, and under the beam of the flashlight, we could clearly see these sparse dark red blood stains.

It took a lot of effort for the criminal police to extract all the blood stains that had been coagulated, and when they got out of the abandoned factory, the stench of the sky disappeared, and the fresh air was breathing, and the mood of all of us did not improve, and the oppressive atmosphere hung over each of us.

The car was driving, I was in the same car as Jiang Jun and Xie Jing, Xie Jing and Jiang Jun kept their heads down and didn't speak, I could see that they were all worried about Wang Xin. Those blood stains have coagulated for a long time, but they can still be identified using forensic technology, but it is more difficult.

Wang Xin's shirt, bloodstains, I don't want to connect these two things, but the facts are very clear, the bloodstains are likely to be Wang Xin's. The car was bumpy, the night was hazy, all the way, I carefully looked around through the car window, I found no trace of the mysterious man, I knew that this was definitely not the last time I met the mysterious man, and the next meeting, I will definitely not be in the same passive situation as the previous two times.

It was late at night, Xie Jing contacted the appraisal staff overnight, and when we arrived at the appraisal center, the lights in the appraisal center were already on. The forensic personnel who came from home stood at the door and waited for us, and after getting out of the car, Xie Jing didn't say anything, and immediately handed over the bloodstains extracted from the scene to the forensic personnel.

Seeing that Xie Jing was in such a hurry, the appraisers didn't dare to ask more, and immediately took the bloodstain sample into the appraisal room. We waited anxiously outside the door, and the minutes ticked by, but the door to the laboratory had no intention of opening at all. The criminal police brought me and Jiang Jun a little food, Jiang Jun had no appetite, and I didn't want to eat either.

Xie Jing has called up Wang Xin's DNA sample and bloodstain sample, which are on file at the police station. Xie Jing closed his eyes and prayed in his mouth, hoping that the bloodstain would not be Wang Xin's. At this time, the door of the appraisal room opened, and the appraiser slowly walked out of the appraisal room.

Jiang Jun and Xie Jing stood up for the first time, and Jiang Jun immediately asked about the appraisal results. Everyone stared nervously at the appraiser, who took off his mask and told us that the bloodstains were not the same person.

Through a preliminary appraisal overnight, the appraisers confirmed that the coagulated blood brought back by the police belonged to two different people, and through comparison, the blood of one of them was identified as the blood of Wang Xin on file with the police station. The moment he heard the result, Jiang Jun was almost untenable.

I held him, Jiang Jun shook his head excitedly, and kept shouting that it was impossible, no matter how everyone persuaded him, Jiang Jun just couldn't calm down. Many criminal policemen were also panicked, and the only one who could stay calm was Xie Jing.

"Jiang Jun, don't worry, there are so few bloodstains, Captain Wang may not really have an accident." Xie Jing said to Jiang Jun.

I nodded, Xie Jing's analysis was not unreasonable. Whether it was the shirt or the steps, there was very little blood left, and it stands to reason that there would never be so little blood from a person's fatal wounds. Even if the staircase wasn't the site of the first injury, there shouldn't be so little blood left.

And, before I returned, I carefully looked at the distribution of the blood stains, which were not in the form of spurts, nor in the form of irregular outflows, but in the form of drips. There were only a few traces of it, but it contained the blood stains of two people, and it was impossible for two people to sit down on such a small range of steps, so the blood stains seemed to be deliberately dripped by people, not stained by two people who were injured at the same time.

Hearing my analysis, Jiang Jun was like a life-saving straw, and he asked me what was going on.

I turned my head and asked the examiner, "When did the blood remain?" ”

The expert immediately answered my question and told me that, based on the degree of clotting of the blood and other characteristics, he believed that the blood had been stained within 72 to 80 hours from now. I calculated the time, that is, the blood stains were left about three days ago.

Wang Xin's shirt and blood stains were found at the scene, which does not prove that Wang Xin must have been to the abandoned factory. Just that little bit of blood, I have no way whether Wang Xin has really been killed, if he is really killed, the murderer will not leave Wang Xin's shirt at the crime scene.

There are two other possibilities, one is that Wang Xin was not killed, but he wanted to reveal some information to us, so he left his shirt. If that were the case, the shirt must have hidden a very important message, otherwise the mysterious man would not have appeared at the abandoned factory and taken the shirt away.

Another possibility is that Wang Xin has never been to the abandoned factory at all. The shirt and the bloodstains were deliberately left in the abandoned factory by others, but this possibility indicates that Wang Xin has fallen into the hands of others, and has even been killed elsewhere.

"What about the other man's blood?" I asked again.

The appraiser said that compared to Wang Xin, there were more blood stains left in the other person, Xie Jing thought about it, and immediately asked people to find the owner of the blood according to the blood analysis, but this was almost a needle in a haystack. After coming out of the appraisal center, Jiang Jun lost his mind for a while, and we did not go back to the hotel, but returned to Jiang Jun's house.

It has been a long time since no one lived, the house is very stuffy, and like the potted plants in the police station, the plants on the windowsill of Jiang Jun's house have died because they have not been watered for a long time, and Jiang Jun's mood has become worse when he sees this scene. Jiang Jun took the kettle and tried his best to water those plants, but those plants had already exuded a burst of dead air, how could they be saved.

"Jiang Jun, now is not the time to panic." I patted Jiang Jun on the shoulder.

Jiang Jun slammed the kettle in his hand to the ground, his eyes were red, and he shouted angrily: "What do you know! ”

This is the first time Jiang Jun has spoken to me like this, Jiang Jun is not tall, but his face is very delicate, at this moment, his face is red, and the green tendons on his neck are bursting up. I was slightly stunned, Jiang Jun realized that he had overreacted, he didn't speak, and walked straight into his room.

I didn't bother him, he needed time to figure it out.

I went into the same room where Xu Yi and I had slept before, cleaned it briefly, and I lay down and fell asleep. The next day, when I went out of the room, I found Jiang Jun sitting on the sofa, Jiang Jun found me immediately, he lowered his head and apologized to me, saying that he was too excited.

"Jiang Jun, I understand your feelings, just a few days ago, Du Lei's body was just discovered, and I still don't know why he committed suicide. If you keep going like this, it's hard to find Captain Wang. I said to Jiang Jun.

Jiang Jun nodded, he got up, and said that he wanted to go to the police station, and now he can only rely on the police station.

Soon, we rushed to the police station, and Xie Jing told us that the police had retrieved surveillance cameras on major busy roads leading to places where abandoned factories might pass. Through overnight investigations, they found no suspicious vehicles and pedestrians. After returning last night, Xie Jing also handed over the warheads and shells extracted from the scene to the appraisal center.

Xie Jing said that the appraisal results had come out, and he handed me the appraisal report on the table. I immediately flipped through the report and looked at it carefully, it was very important because it might involve the identity of the mysterious man.

The appraisal report recorded a detailed analysis of the bullet model and ammunition traces, but unfortunately, the appraisers were unable to find a specific match for the gun based on the ammunition traces, and the appraisers believed that it was a black gun, that is, made by an underground gun factory. Based on the marks on the bullet casings and bullet heads, the experts guessed that the gun used by the mysterious man was crudely made, and was made in imitation of a semi-automatic pistol commonly used by the police in the 80s.

The pistols used by the criminal police have all been replaced, and the generation of semi-automatic pistols imitated by the mysterious man has a slow rate of fire, low power, and low accuracy, not to mention a rough imitation gun.

I frowned, the mysterious man could shoot so accurately with such a gun......
