The car bumped for a long time, and we finally arrived at the police station again, except for the people on the night shift, everyone was already off work. After entering the office, Ma Tao turned on the light, it was very hot in the office, Ma Tao complained a few times, and turned on the ceiling fan above his head. At his beckoning, the person on duty on the night shift came in to make a confession for Xiao Xiao.

It was already nine o'clock in the evening after recording the confession, Ma Tao was going to let someone send Xiao Xiao back, Xiao Xiao's home was not too far from the police station, and there would be a bus, so he didn't let anyone from the police station send it. When Xiao Xiao left, the police station was quiet again, and Ma Tao asked us to go back and rest quickly, there are still many things to be busy tomorrow.

has been investigating for so long, and many things should have some news, and many criminal policemen who went out to investigate are also rushing back.

Back at the hotel, I was about to enter the room, Jiang Jun stopped me, he glanced at Xu Yi, Xu Yi immediately understood, went directly into the room, and left the place to me and Jiang Jun. The aisle was empty, it seemed to have just been sterilized, and the smell was very strong. Jiang Jun hesitated for a long time, and finally said that he had figured it out a little.

Jiang Jun said that he had to talk to Wang Xin in person, no matter what the outcome of the matter was, Wang Xin had raised him for so many years, and many things had to be given Wang Xin a chance to explain. Jiang Jun didn't wait for me to answer, he took out his mobile phone and dialed Wang Xin's phone number, but the result was the same, turning off the phone.

Jiang Jun was afraid that something would happen to Wang Xin, so I told him that I had asked Xie Jing and the people from the Guangdong City Police Force to keep an eye on us, and as soon as Wang Xin's whereabouts were known, they would notify us. Wang Xin carried his luggage out of their community, and after listening to my comfort, Jiang Jun also said that nothing should happen to Wang Xin, maybe it was really as Wang Xin said, he just went out to play.

Jiang Jun had no way to understand why Wang Xin resigned, Wang Xin had not yet reached the age of retirement, and he once told Jiang Jun that he would work as a police officer for the rest of his life until he could no longer do it. Jiang Jun was influenced by Wang Xin since he was a child, so he embarked on the road of the police, and was full of ideals and justice.

"Maybe there's something unspeakable." I replied to Jiang Jun that I was afraid that Jiang Jun's mood would be unstable, so I didn't dare to mention it, but now that he mentioned it himself, I no longer shy away from it. I asked Jiang Jun if the man who called him had any characteristics, and Jiang Jun said no, it was a very ordinary voice that he didn't recognize.

As for the phone number, it is also the number of the public phone booth.

"Jiang Jun, you have to be careful, this person suddenly told you this, and I don't know what the purpose is, you have to be careful, he is likely to be an acquaintance of you and Captain Wang." I reminded Jiang Jundao. That person knew Jiang Jun from childhood to adulthood, and even Wang Xin personally killed Jiang Jun's father, which showed that the other party knew Jiang Jun and Wang Xin very well.

Jiang Jun thought about it carefully, and he said that he had many acquaintances of his uncles, and those people had followed Wang Xin for more than ten or twenty years, and they were all Wang Xin's henchmen, so it was unlikely that he would do such a thing. However, he said that he would still keep an eye on it, and after discussing it with me, Jiang Jun entered the room.

Xu Yi had already taken a shower, and I told Xu Yi everything about it, and Xu Yi was also very relieved, saying that it would be good if Jiang Jun could figure it out. I don't know where Wang Xin went, but I'm worried about the day when Wang Xin and Jiang Jun meet. I told Wang Xin a long time ago that paper can't hold fire, even if Wang Xin killed Jiang Jun's father for justice, but the hatred of killing his father is not shared, I don't know if Jiang Jun can understand Wang Xin.

After a night's rest, we received a call from Ma Tao early the next morning. After running around for several days, when Ma Tao called us, Xu Yi and I were still asleep, and Jiang Jun, like us, had not yet woken up. After a brief wash, we rushed to the police station.

According to Ma Tao, tomorrow morning, Zhushi will usher in the first typhoon of summer, and when we go out, it will be cloudy, and the wind will be much stronger than usual.

At nine o'clock in the morning, we rushed to the police station. Ma Tao welcomed us into the office, saying that he might have found where the arsenic that killed Sun Xiang came from. Ma Tao told me that he followed my train of thought and started with regular research institutions and units, and after many investigations, they found a small chemical research center, which had recently lost a large number of chemicals, among which arsenic trioxide was missing.

The criminal police who were sent out are now waiting for us to go over to the research center, and the midwife who delivered Jiang Yingcheng has also received news, she lives on the outskirts of Zhushi, and it only takes more than an hour to drive from here. Ma Tao was very excited, saying that this harvest was not small, and immediately took us off in person.

We don't dare to waste any more time, and I am afraid that the typhoon will last all day this morning, and our investigation will be affected as a result. On the way, Ma Tao told me that Xiao Jiang still refused to take the medicine, and the wound on his waist was even more inflamed, so he asked several people to send Xiao Jiang to the hospital.

Xiao Jiang's legs were chained, his hands were handcuffed, and there were several criminal policemen guarding him, so Ma Tao told us not to worry. Finally, the car drove to the research center, and it was half past nine in the morning. The detective waiting at the door welcomed us into the office of the head of the research center.

The criminal police said that there were cameras in the research institute, but on the day of the theft of the chemicals, the line was checked, so the cameras were not turned on, but there was a surveillance camera on the road at the entrance of the research center, and another criminal police officer had already gone to the relevant unit to retrieve the videotape.

When asked about the details, the person in charge of the research center said that the time of the drug theft was at night, and when they came home from work, they found that the research center had been stolen the next day. But strangely, all the valuable identification instruments and chemical instruments were not lost, only a bunch of relatively inexpensive chemicals were lost.

That's why they didn't call the police. I observed the topography of the research center, and there was not a lot of space, and there was no way to climb up to the back door, so I had to enter and exit through the main entrance. The thieves are certainly not in it for the money, otherwise those valuable chemical instruments would have been gone long ago.

Obviously, the other party came for the chemicals. Moreover, it is not necessarily a coincidence that the day of the chemical theft happened to be checked by the surveillance camera line.

Soon, the detective who went out to get the surveillance camera returned, and we found a computer at the research center and began to observe what happened that night. It's dark at night, and the monitoring screen is not very clear, if there are no street lights, the monitoring screen must be pitch black.

At about two o'clock in the morning, a person appeared on the surveillance screen, wearing black clothes and a black cap. With all of us watching, he entered the research center.

Originally, we thought that he would use a tool to open the lock and enter the door, but to our surprise, the man picked up a large rock from the side and slammed it against the lock on the door, not afraid of being discovered. Soon, the lock was smashed open by him, and he pulled open the iron door and ran straight inside.

At two o'clock in the morning, there were no people on this street, and there were not many residents around, and this man seemed to understand this and dared to be so bold. About ten minutes later, he came out of the research center with a large bag of chemicals, which he had stolen.

He looked around and immediately ran away, his run, we are all more sure of the owner of this figure, it is indeed Xiao Jiang, Xiao Jiang's upper body and lower body are not particularly coordinated, when he runs, if you look carefully, it is easy to identify. Ma Tao slapped the table and said that Xiao Jiang must be the murderer of Sun Xiang.

The criminal police have recorded the content of the person in charge's questioning, and the surveillance camera has also been brought back to the police station by the criminal police as one of the evidence. Immediately, we drove to the next stop, and at twelve o'clock in the afternoon, we finally came to the outskirts of Zhushi, where there were already three criminal policemen guarding here.

We knocked on the door and entered a small brick house, and there was only one person in the brick room, and she was sitting on a bamboo chair, with white hair, and she couldn't even open her eyes.

As soon as we came in, she began to cry bitterly, and in an instant, I understood.
