Since it was a murder case, the evidence collected on the scene was naturally creepy.

I was alone in the room with Jiang Qinghan, looking at the photos one by one, and I felt a strange feeling, as if I was studying horror movies together. However, Jiang Qinghan was used to similar scenes and would not be like those little girls, because of fear and tension, holding the man's arm.

"At around 17:00 on May 26, 1998, Bai, a 23-year-old female employee of Shuitian Company, was killed at home at No. 112 Yongfeng Street. During the inspection, the victim's neck was cut open, her top was torn, her lower body was naked, and she had 26 knife injuries in total."

"At around 2:50 pm on July 27, 2004, Shi, a female temporary worker from the Power Supply Bureau, was killed in her single dormitory. She was 19 years old when she was killed. On-site inspection found that the victim's neck was cut open and there were 36 knife injuries in his upper body."

"At around 11:00 on the 20th of the month, Luo, a 28-year-old female textile factory worker, was killed in her home in the family area of ​​the factory's bungalow. During the inspection, it was found that the victim's neck was cut open, his pants were pulled to his knees, and his hands were missing."

...

After reading the information, Su Tao analyzed: "The suspect was born in 2018, a male, aged about 43 to 50 years old, and a height of about 1.68 meters to 1.76 meters. He lived in Hanzhou for a long time and had serious sexual perverts or physiological defects, especially sexual intermittent disorders, and had a hatred mentality towards women. He had the conditions for living alone, and his personality traits basically tended to be introvert, depression, indifferent, not good at socializing, withdrawn and unsociable, extremely patient in doing things, and has a very obvious dual personality, and is extremely concealed in doing things."

Jiang Qinghan nodded and said in a deep voice: "Similar to our judgment, the suspects are extremely concealed. When committing crimes, they often choose young women as their targets, rape and kill them. Most of the time for committing crimes chooses to work from Monday to Friday. The means of committing crimes are mostly followed, knocking on the door and other means entering the house for murder, which is extremely cruel."

Su Tao frowned and said, "In theory, Hanzhou is so big. There are cameras everywhere now, so it should be able to lock some people."

Jiang Qinghan also said: "In 2013, a post appeared on a well-known community forum. The author signed it was Caesar. The post was called. The author used extremely meticulous language to describe the murderer's appearance, personality, method of committing crimes and even psychological activities. After the post was published, a netizen named Burning analyzed the words, certain language details and writing history of the original text from multiple angles, strongly implying that Caesar is related to the case. On the basis of this realistic unsolved case that has been buried for 12 years, the popularity of the theme post with various elements such as thriller, fear, and suspense has continued to heat up. In the page of the chat, related discussions about this case continue to appear."

Su Tao said: "The police should be able to find Caesar and Burning, these two people, right?"

Jiang Qinghan nodded and said, "We found Caesar, who is a graduate student in the law department of Qiongjin University. His father is a criminal policeman, so he likes to study this since he was a child. That post was analyzed based on the information. He is only 28 years old now, he is not strong, has severe hyperopia, and has been studying for a long time, so he does not have the conditions for the plan."

"Where is the case called burning?" Su Tao asked softly.

Jiang Qinghan shook his head and sighed: "The IP address of the post of Burning Fire shows an Internet cafe from Ganzhou Province. At that time, the real-name system of the Internet was not yet implemented, so he was not found."

Su Tao nodded, sighed, and said in a serious tone: "The reason you decided to take this case back and study is because you are worried that he will commit a crime this year?"

Jiang Qinghan said in a serious tone: "From time, we have discovered a rule that he has committed crimes every six months since 2008, and the longest time will not exceed one year. It has been five months since the last crime. We judged that he committed the crime in the near future."

Su Tao recognized Jiang Qinghan's view, "From a psychological point of view, for a habitual criminal, after enjoying this bloody stimulation, he will continue to take risks and will never stop."

Jiang Qinghan sighed and said, "So we must stop the tragedy."

Su Tao held his chin and continued to read the information, saying in a deep voice: "I will go to JAC Hospital to check the files tomorrow, and there may be new discoveries."

"Oh" Jiang Qinghan looked at Su Tao suspiciously. She didn't understand what the investigation had to do with Jianghuai Hospital.

Su Tao explained in a serious tone: "From the various behaviors of the criminal, if nothing unexpected happens, he is an intellectual and has a status. Otherwise, it would be impossible to be so meticulous. If he lived in Hanzhou for a long time and was physically ill, which hospital would you usually seek medical treatment?"

Jiang Qinghan's eyes lit up and nodded, "Then he would definitely choose JAC Hospital. However, with so many patients in the hospital, can he find clues?"

Su Tao said in a deep voice: "Although there are many patients in JAC Hospital, there are only so many expert directors. If I were that person and I got sick, I would definitely go to the chief expert so that I could rest assured. Therefore, I can further narrow the scope and specifically find patient information for those director-level doctors. Then further screen them with age and body characteristics, and potential objects can be selected."

Jiang Qinghan laughed at herself and said, "Why didn't I expect this?"

Su Tao patiently explained: "Everyone has his own familiar field. You are a criminal policeman, and you pay more attention to evidence. I am a doctor, and I pay more attention to the criminal's condition. The focus is different, and the entry point of choice is also different."

Jiang Qinghan nodded heavily and smiled and said, "Then I'll trouble you about this matter. Is there any place to cooperate?"

Su Tao smiled and said, "You have to find a way to let me go and read the hospital's files with justification. Also, this matter should be kept confidential and not let too many people know about it. Otherwise, it may cause the criminals to be alert, alarm the enemy, and increase the difficulty of investigating the case later."

Jiang Qinghan smiled and said, "I always feel that it can make things easier when talking about the case with you."

Su Tao smiled and joked: "Talking with me more in the future can increase inspiration."

Jiang Qinghan shook his head and smiled, "I know I'm very busy. You have more important things to deal with."

Su Tao shook his finger and said seriously: "The police and doctors often have the same goals. For example, if you want to find this criminal, you want to save people. I am a doctor, isn't it just to save people? This is called the same destination."

Jiang Qinghan smiled and said, "I hope I can find him before the New Year so I can have a safe and comfortable year. Zhang Zhen and the others have been staying up all night long. Yesterday, they complained to me that they would like to add the year-end bonus."

As Jiang Qinghan was promoted to deputy director, Zhang Zhen's status in the police station also increased, and he is now the head of the criminal investigation team.

Su Tao suddenly had a serious and solemn expression, and he said in a deep voice: "You must pay attention to safety in recent times."

"Don't worry, I'm your master, don't underestimate me. If that criminal really hits me, it's his unlucky." Jiang Qinghan said with a smile.

Su Tao knew that Jiang Qinghan misunderstood his concerns and reminded him: "Do you still remember the Witchcraft Sect? After they left their eyes, they lurked in Hanzhou. All signs indicate that their target is you. The visible enemy is not scary. The key is that the style and method of the Witchcraft Sect's conduct are very hidden and cannot be guarded against."

Su Tao once reminded Jiang Qinghan on the phone, and Jiang Qinghan nodded slightly, "I will pay attention. During this period, I have basically never eaten outside and will not act single."

When Su Tao heard Jiang Qinghan say this, he felt a little relieved. There were still people from the beacons in secret that they were monitoring everything, so the Witch War Sect had to throw a rat and was afraid of it. There was no action yet.

In fact, Su Tao thought that the enemy was in the dark and he was in the light, waiting for the other party to reveal his flaws, would be too passive. The clever way was to seduce the other party.

How to design it needs to be carefully considered.

Su Tao's current layout methods and strategies have made rapid progress, and it has long been different from what he used to be.

Su Tao patted his forehead gently and smiled, "I almost forgot something, I'll give you a gift."

Jiang Qinghan was slightly stunned and said, "Although you know you are not short of money, there is no need to always prepare gifts for me and Yansha. You are still young and you have to marry a wife in the future."

Su Tao joked: "You are my master, so it's time to respect you. As for marrying a wife, if you meet a strong person, you might borrow money from you in the future." As he said, he took out a mobile phone box from the medical box.

Jiang Qinghan was a little surprised, but unexpectedly Su Tao bought him a new mobile phone.

While opening the box, Su Tao explained: "Your phone has been too long, so I bought you a new one. It is the Android system you are familiar with. It runs very fast. You should use it for two days and get used to it."

Jiang Qinghan shook his head and smiled bitterly: "I used my phone well before."

She has little requirements for mobile phones. As long as she can answer calls, she can use some basic communication software.

Su Tao said confidently: "Wait for a few days to use it, you will know how bad your phone is."

After saying that, he took out the phone card from his old phone and found it was a big card. He frowned and compared it to the card slot. Then he used a silver needle to carefully cut it, making the big card into a small card. After installing it, it was indeed possible to use it.

Jiang Qinghan took the phone from Su Tao, looked at the address book, and smiled and said, "Why are there only your number?"

"Because I'm the most important?" Su Tao laughed, as if he had been waiting for this question.

Jiang Qinghan glared at Su Tao with annoyance, "The numbers on your mobile phone used to be very important, but they can't be lost."

"Now mobile phones are very user-friendly, and transferring phone numbers is the easiest thing." Su Tao used the Bluetooth function of the phone to transfer all the numbers on the old phone to the new phone.

"Master, look at me!" Su Tao called out to Jiang Qinghan.

Jiang Qinghan subconsciously turned around, but saw Su Tao leaning over and there was an extra group photo on his phone.
