Since it is a homicide case, the evidence collected at the scene is naturally creepy.

Alone in the room with Jiang Qinghan, looking at the photos carefully one by one, there was a weird feeling, as if they were studying horror movies together, but Jiang Qinghan was used to seeing similar scenes, and he would not be like those little girls, who grabbed the man's arm because of fear and nervousness.

"At about 17 o'clock on May 26, 1998, Bai, a 23-year-old female employee of the paddy field company living at No. 112 Yongfeng Street, was killed at home, and the police found that the victim's neck was cut, his shirt was torn, his lower body was naked, and there were 26 knife wounds on his upper body. ”

"At about 2:50 p.m. on July 27, 2004, Shi, a female temporary worker of the Power Supply Bureau, was killed in her single dormitory, 19 years old at the time of the murder, and the on-site investigation found that the victim's neck was cut open and there were 36 stab wounds on the upper body. ”

"At about 11 o'clock on November 20, 2010, Luo, a 28-year-old female textile factory worker, was killed in her home in the family area of the factory's bungalow. ”

……

After reading the information, Su Tao analyzed: "The suspect was born between 1964 and 1971, male, aged between 43 and 50 years old, about 1.68 meters to 1.76 meters tall, he has lived in Hanzhou for a long time, has a more serious sexual abnormality, or physical defects, especially with intermittent disorder of sexual function, and has a hatred for women." There are conditions for living alone, and the personality traits basically tend to be introverted, depressed, indifferent, unsociable, withdrawn and unsociable, very patient in doing things, and have a very obvious dual personality, and do things very secretively. ”

Jiang Qinghan nodded, and said in a deep voice: "Similar to our judgment, the suspects are extremely hidden, and when committing crimes, they mostly choose young women as targets, rape and then kill, and most of the crime times are chosen to work from Monday to Friday, and the means of committing crimes are mostly tailgating, knocking on the door and other means to enter the house and commit murder, and the means are extremely cruel. ”

Su Tao frowned and said: "It stands to reason that Hanzhou is so big, and now there are cameras everywhere, which should be able to lock some people." ”

Jiang Qinghan said: "In 2013, a post appeared on a well-known community forum, signed by Caesar, and the post was called "Some Thoughts on the Hanzhou Serial Murder Case", in which the author used extremely meticulous language to describe the murderer's appearance, personality, modus operandi, motives and even psychological activities. After the post was posted, a netizen with the ID name Burning analyzed the wording, some linguistic details and writing process of the original article from multiple angles, strongly suggesting that Caesar was related to the case. This article is based on a 12-year-old reality unsolved case, and the popularity of the theme post with various elements such as thriller, fear, and suspense continues to heat up. In the miscellaneous section, there are constantly discussions related to this case. ”

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

Jiang Qinghan nodded and said, "We found Caesar, he is a graduate student in the law department of Qiongjin University, and his father is a criminal policeman, so he likes to study this aspect since he was a child." That post was analyzed by him based on the data. He is only twenty-eight years old now, his body is not strong, he has severe farsightedness, and he has been studying for a long time, so he does not have the conditions for the program. ”

"What about the case called incineration?" asked Su Tao softly.

Jiang Qinghan shook his head and sighed: "The IP address of the burning post shows that it is from an Internet café in Ganzhou Province, and the network real-name system has not been implemented at that time, so he has not been found." ”

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

Jiang Qinghan said in a solemn tone: "From the time point of view, we have found a pattern, since 2008, he has committed crimes every six months or so, and the longest time will not exceed one year, it has been five months since the last time he committed the crime, and we judge that he committed the crime in the near future." ”

Su Tao agrees with Jiang Qinghan's point of view, "From a psychological point of view, for a habitual offender, when he enjoys this bloody thrill, he will continue to take risks and will never stop." ”

Jiang Qinghan sighed and said, "So we have to stop the tragedy from happening." ”

Su Tao held his chin, continued to read the information, and said in a deep voice: "Tomorrow I will go to Jianghuai Hospital to adjust the files, maybe there will 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 solemn tone: "Judging from the various behaviors of the criminal, it is not surprising that he is an intellectual, as well as his status, otherwise it is impossible to be so thoughtful. If he has lived in Hanzhou for a long time and is sick, which hospital do you think he would normally seek medical treatment in?"

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

Su Tao said in a deep voice: "Although there are many patients in Jianghuai Hospital, there are so many expert directors. If I were that person and I got sick, I would definitely go to the chief specialist, so that I could rest assured. Therefore, the scope can be further narrowed down to specifically find the patient information of those director-level doctors. Further screening with age and body characteristics will allow you to screen out potential candidates. ”

Jiang Qinghan laughed at himself: "Why didn't I think of this?"

Su Tao patiently explained: "Everyone has their own familiar field, you are a criminal policeman, and you pay more attention to evidence. As a doctor, I pay more attention to the condition of the offender. The focus is different, and the entry point chosen is also different. ”

Jiang Qinghan nodded heavily and said with a smile: "Then this matter will trouble you, is there anything you need to cooperate." ”

Su Tao smiled: "You have to find a way to let me go through the hospital files in the name of righteousness." In addition, this matter should be kept confidential and not let too many people know about it, otherwise, it may arouse the vigilance of the offender, startle the snake, and increase the difficulty of investigating the case in the later stage. ”

Jiang Qinghan smiled and said, "When I talk to you about the case, I always feel that it can make things simpler." ”

Su Tao smiled and quipped: "Chat with me more in the future, you can increase your inspiration." ”

Jiang Qinghan shook his head and smiled: "I know it's busy. You have more important things to deal with. ”

Su Tao shook his fingers and said very seriously: "The police and the doctor often have the same goal. For example, if you want to find this criminal, you want to save people. Isn't it true that I am also a doctor to save people? ”

Jiang Qinghan said with a smile: "I hope to find him before the year, and it will be better to have a good year." Zhang Zhen: They have been staying up all night, and they complained to me yesterday that they wanted to increase the year-end bonus. ”

With Jiang Qinghan's promotion to deputy director, Zhang Zhen's status in the police station has also risen, and he is now the head of the criminal investigation team.

Su Tao's expression suddenly became serious and dignified, and he said in a deep voice: "You should pay attention to safety recently. ”

"Don't worry, I'm your master, don't underestimate me. If that criminal does hit me, he's out of luck. Jiang Qinghan smiled.

Su Tao knew that Jiang Qinghan had misunderstood his worries, and reminded: "Do you remember the Wu Gu Sect? After they left their eyes, they were secretly lurking in Hanzhou, and there were all kinds of signs that their target was you. The visible enemy is not terrifying, and the key witch Gu Sect's style and modus operandi are very hidden and impossible to prevent. ”

Su Tao once reminded Jiang Qinghan on the phone, Jiang Qinghan bowed slightly, "I will be careful, I basically never eat out during this time, and I will not act alone." ”

Su Tao heard Jiang Qinghan say this, and was slightly relieved, there were still people in the dark who were monitoring everything, so the Wu Gu Sect had to throw a rat taboo, and there was no action yet.

In fact, Su Tao pondered that the enemy is in the dark, and he is in the light, waiting for the other party to reveal his flaws, it is too passive, and the smart way is to seduce the other party.

How to design it still has to be carefully pondered.

Su Tao's current layout of means and strategies, rapid progress, has long been different from what it used to be.

Su Tao patted his head lightly and said with a smile: "I almost forgot one thing, I will give you a gift." ”

Jiang Qinghan was slightly stunned and said, "Although I know that you are not short of money, there is no need to always prepare gifts for me and Yansha." You're still young, and you'll have to marry a daughter-in-law in the future. ”

Su Tao joked: "You are my master, and you should be honored honored." As for marrying a daughter-in-law, if you meet a strong one, you may be able to borrow money from you in the future. As he spoke, he took out a mobile phone case from the medical box.

Jiang Qinghan was a little surprised, but he didn't expect Su Tao to buy himself a new mobile phone.

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

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

She doesn't have too high requirements for mobile phones, as long as she can make and receive calls, she can use some basic communication software.

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

After speaking, he took out the phone card from the old mobile phone, found that it was a big card, frowned, compared it with the card slot, and then used a silver needle, carefully cut, and made the big card into a small card.

Jiang Qinghan took the mobile phone from Su Tao's hand, looked at the address book, and said with a smile: "Why 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 angrily, "The numbers on the mobile phone in the past were very important, but they can't be gone." ”

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

"Master, look at me!" Su Tao shouted Jiang Qinghan.

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