Serious Crime Unit 1

Chapter 852 Human Brain Control (8)
Wu Jiang and Xiao Ke came to the crime scene again. They stood next to the floor-to-ceiling windows on the 8th floor and looked into the distance. At this time, it was drizzling in the sky. A group of white pigeons were flying around in the rain. From time to time, they heard chirping sounds. There is a 12-story building there, which is Baihua Town Hospital in Jiangbei District. The hospital is under construction and has been topped out, but it is not open yet.

Wujiang visually measured the distance. It was about 90 meters away from the crime scene. Its front was facing the Wanwei Building. It was a good observation point. There was no one in the town hospital. The criminal was most likely standing on it to control the remote control. , causing Xu Yi to fall to death.

Wu Jiang and Xiao Ke left the crime scene and walked towards the hospital. The hospital was surrounded by walls and had only a simple iron door. There was a security room next to the iron door. A security guard was sitting there watching TV and saw them breaking in. Come on, he shouted at them to stop. Xiao Ke threw the police officer ID card to him. After he read it, he let them in with a smile on his face.

The two of them came to the 8th floor, because it was almost the same height as the 8th floor of Wanwei Building, and they could see the crime scene clearly by looking straight up.There are a total of 8 rooms on the 30th floor of the hospital. It is unknown which room the suspect used the remote control to kill from.Of course, the suspect may also be standing on the 9th or 10th floor, or higher.

Wu Jiang decided to start the investigation from the middle room on the 8th floor, and then expand to both sides.Because the floor has not yet been laid, there is a rough cement floor above, which is covered with dust. When your feet step on it, you will leave obvious shoe prints, which makes their work easier.

There were many messy footprints in the room. Wu Jiang squatted down and observed. Most of these shoe prints were left by Jiefang shoes or sports shoes. The owner of the shoe prints should be a bricklaying worker.Wu Jiang believes that the suspect should have committed the crime wearing high-end leather shoes or travel shoes.Therefore, he pays special attention to these two shoe prints.

Wu Jiang has seen countless shoe prints, and he can almost distinguish the shoe patterns of leather shoes or travel shoes from international and domestic brands.Wujiang started to investigate from east to west, and Xiao Ke started to investigate from west to east. According to the security guard at the gate, no one had entered this building for at least two months, and today was only half a month before the incident, so , if fresh footsteps are seen, it is questionable.

Wu Jiang found several leather shoe prints next to the window of a room. The shoe prints were fresh and complete. He took a closer look and judged that they were a pair of 2018 Pierre Cardin leather shoes. It is impossible for workers to wear international famous brand leather shoes. Lay bricks.

This pair of shoe prints were left by size 42 leather shoes, with a total of 15 shoe prints, some of which were covered by subsequent shoe prints.Wu Jiang squatted down to take photos of the shoe prints. After taking the photos, he asked Xiao Ke to come over and take a look. After Xiao Ke saw it, he also felt very suspicious.Wu Jiang found that the owner of the shoe print was eight steps outside. According to visual inspection, the suspect should weigh more than 70 kilograms and be about 178 centimeters tall.

Xiao Ke found two more cigarette butts in the corner, which were Chinese cigarettes. Construction workers would definitely not smoke such good cigarettes. If these cigarette butts were left by the suspect, it would be ideal, because Luo Jin could extract the suspect from the cigarette butts. Human DNA or fingerprints.

After extracting the shoe prints, they went to investigate other rooms and other floors, but found nothing new. The only suspicious thing was the pair of Pierre Cardin shoe prints. Wu Jiang believed that it was most likely left by the suspect. If the shoe prints or If the DNA can be compared successfully in the database, it will get twice the result with half the effort.

Wu Jiang entered the suspect's shoe prints into the computer for search. There were no matching shoe prints, which meant that the suspect had no criminal record. However, after the murderer was captured, these shoe prints could be used as physical evidence.

Luo Jin extracted the suspect's saliva from the cigarette butts and used the saliva to make DNA. After the results came out, he entered them into the computer and compared them in the DNA database. There was no matching DNA.

"Old Wu, are there any monitors installed at the Baihua Town Hospital construction site?" Jiang Yiming asked.

"The security guard said that there was only one monitor installed at the gate. However, we checked the surveillance video on the morning of March 3 and found no suspicious people entering the construction site. The security guard on duty also said that no one entered at that time."

"The construction site wall of Baihua Town Hospital is only two meters high. The suspect can enter the construction site from any part of the wall. The security guard said that they rarely patrol the construction site. I think the suspect should have entered Baihua Town Hospital from somewhere on the wall." Xiao Ke said.

"Can you find any traces of climbing on the wall?" Jiang Yiming asked Xiao Ke.

"The wall is not painted and is made of rough blue bricks. Even if someone climbs it, it is difficult to leave traces. We also thought of this and observed the wall with Angkor. Due to time constraints, we only took a rough look. , no trace of anyone climbing was found.”

"The suspect has a strong counter-investigation ability and will not easily leave clues. This is a two-step murder case that has been planned for a long time. First, the murderer will crack Xu Yi's parietal bone, and then crack his parietal bone." The mastermind who implanted radium tubes in his head is an extremely cunning guy," Wu Jiang said.

"Zhou Ting and I have already investigated Kong Jun, the chairman of Dicai Construction Group Company. He also has an alibi. Of course, these rich bosses generally do not kill people themselves. Therefore, this case is very complicated and will take a long time. Prepare for a tough battle. Where should we start next?”

"The best way is to investigate all the people involved in Xu Yi's craniotomy, such as Tian Xiaodong's assistants and nurses. Continue to ask Tian Xiaodong to see who is the most suspicious. Secondly, check all the surveillance videos outside the walls of Baihua Town Hospital, you may find suspects."

"How did the murderer know that Xu Yi was going to inspect the construction site? Was there a spy who tipped off the murderer? Or did the murderer follow Xu Yi all the way to the construction site? If he followed Xu Yi all the way to the construction site, we can call Xu Yi from Surveillance footage from the company on the way to the construction site may reveal the suspect.”

"I asked Yingying and Xiaorou to check Xu Yi's surveillance video from the company to the construction site. Lao Wu and Xiaoke continued to ask Tian Xiaodong, and Zhou Ting and I went to check the private or security monitors outside the wall of Baihua Town Hospital. "

Wu Jiang and Xiao Ke came to Tian Xiaodong's office again. Tian Xiaodong did not feel repulsive towards them, but cooperated with them very much. "Dr. Tian, ​​we have eliminated your suspicion, but we believe that everyone involved in Xu Yi's craniotomy at that time was suspect, such as the nurse."

"Nurse? It's generally impossible for nurses to do this kind of thing. They have almost no chance to get close to the surgery center... Oh, I remembered. I opened Xu Yi's parietal bone and cleaned up the congestion in the skull. Because I felt a little tired, I was afraid that I would lose energy, so I asked my assistant Jiang Chuan to suture the scalp, and he happily performed the suturing operation."

"Jiangchuan? Is he qualified to perform suture surgery?"

"Of course, he is my most capable assistant and can also perform craniotomy and desilting surgery. However, unless there are special circumstances, I will be the one to perform the surgery and he will cooperate."

"Where does he work now?"

"Still in the brain surgery department of the provincial hospital."

"About how many centimeters is he tall?" Wu Jiang thought of the shoe prints extracted on the 8th floor of Baihua Town Hospital. If Jiang Chuan was about the same height as the suspect, half of the case would be solved.

"About 170 centimeters."

Tian Xiaodong's answer was slightly disappointing.Wu Jiang asked Tian Xiaodong to write down the names of those who participated in Xu Yi's craniotomy.Tian Xiaodong wrote down the names of five people and their mobile phone numbers. After Wu Jiang thanked Tian Xiaodong, he and Xiao Ke walked out of his office and drove to the Brain Surgery Department of the Provincial Hospital to find Jiang Chuan.

Jiang Chuan was already the deputy chief physician of brain surgery, but he did not have his own independent office. Wu Jiang called him to the dean's office to talk with him.

Jiang Chuan is of medium build, neither fat nor thin, with small eyes that look like a mouse. He is 34 years old, married and has children. He is very calm when facing Wu Jiang and Xiao Ke.

"Do you know Xu Yi?"

"Xu Yi? Which Xu Yi? I have many patients, hundreds of them."

"It's Xu Yi, the chairman of Tianshan Construction Group Company."

"Oh, I remembered that he once came to our hospital for a craniotomy, which was performed by Director Tian Xiaodong. I was his assistant. After he was discharged from the hospital, I have not had any contact with him. He is the president of a group company. , I can’t reach a high level, you didn’t mention it, I have already forgotten about him.”

"He is dead. After our investigation, we determined that he was murdered. Someone implanted nanoradium tubes in his brain to control his mind and cause his feet to lose coordination. As a result, he fell from the stairs on the 8th floor. He fell to death. Xu Yi had only had one craniotomy in his life. Therefore, all the doctors and nurses who participated in Xu Yi's craniotomy at that time were suspected, and you are also one of our suspects." Wu Jiang's eyes were fixed on him, and he tried his best Capture the changes in his expression.

"Am I suspected? I'm not the chief surgeon, so why am I suspected?" He glanced at Wu Jiang, and then rested his gaze on the wall behind Wu Jiang.

"Tian Xiaodong said that you helped to suture the wound and that you had the opportunity to implant the radium tube into his brain septum. You must cooperate with our investigation."

"You are making things out of nothing, how can I cooperate with you?"

"Just tell the truth. No one is a sage. Who can make mistakes? Just know your mistakes and correct them. Are you going to implant a radium tube in Xu Yi's brain?"

"Me? I am a doctor with medical ethics. How could I do something that is harmful to nature? I advise you to spend your time on others, otherwise you will miss the opportunity."
