After rejecting the marriage, the head of the Qin family was crushed by me.

"I prefer to understand that the criminal suspect has a strong hatred for the entire F continent society, which led to the emergence of such indiscriminate killings." Qin Yelan said, "And I think the possibility of multiple personality disorder can be ruled out. Sex, because he unilaterally intercepted all the information reported to the local police station. Until the day when the No. 11 victim appeared, Mo Mo came across a piece of news that had just been released, saying that indiscriminate killings had occurred in F Continent, and the number of dead There were already as many as ten people, and we only learned about the situation."

"It makes sense." Han Su nodded, "Before I came here, I was still surprised that Mo Mo hadn't started psychological profiling yet, because I had seen the relevant news in Country R five days ago, and it hadn't started yet until When I came in today, I chatted with the person who brought me in, and I realized that you got the news today."

"Well, then let's talk about the situation where the suspects are not the same person." Qianzhe Mian clicked on the information that was divided into five categories, "The first murderer is similar to what we analyzed earlier. He has served in the armed forces. Background, received a good education, especially in the aspects of investigation, trace inspection, and counter-investigation. It is also possible that he is just an ordinary person, but a serious enthusiast of guns, ammunition and criminal investigation, interested in and proficient in this. This person is In life, he is likely to be easily angered or easily incited by others, similar to that kind of passionate young man."

"The second murderer's modus operandi was to rely on brute force to win, either cutting people with a knife or pushing people downstairs. This can also reflect that he is careless in life, not stick to trivial matters, thinks in a straight line, and does not know how to be flexible. Similarly, This kind of person is also very easy to be incited by others and go to extremes. In addition, we focus on the surveillance video at the time of the crime - oh, I forgot to mention, this is a surveillance video that I personally restored. Originally, this section The video was deleted - back to the point, we can take a look at his actions." Qianzhe Mian slowed down the video and pointed at the suspect, "Look, his way of exerting force is quite professional. Next The position of the knife is quite accurate, indicating that he is a professional fighter, and may have been engaged in a career such as boxing, and he must have been in the gladiatorial arena of the underground auction house."

"Are you so sure?" Qin Yelan looked at her.

"Well, I'm sure, because the underground auction house was a property I once placed under the name of the Lancelot family. Until now, I am still the top manager there. Deaths often occur in the arena. Damn it. It's this kind of extremely precise strike." Qianzhe Mian said calmly, "Of course, after the Lancelot family settled in Lingcheng, I asked people to separate the underground auction arena. The industries in the gray area are not It needs to be borne by the Lancelot family.”

"Continuing to talk about the third murderer, I speculate that he has a study and working background in the pharmaceutical industry. I will focus on investigating toxicology graduates who have studied or worked in the pharmaceutical field. They have such a good grasp of the dosage of gelsemenine and aconitine. Accurate, he must have enough relevant knowledge, this is not a level that an ordinary amateur can achieve." Qianzhe Mian looked at Sui Wan, "Do you have any objections to this point?"

"No." Sui Wan turned the pen in his hand, "I have probably seen the toxicology stuff you teach there. It is indeed not simple. If you don't grasp it well, the secret will be exposed. It is not enough for the murderer to escape until now."

"Yes, that's what I mean." Qianzhe Mian nodded, "As for the character... The third murderer must have encountered some kind of accident, which led to a dark heart and hatred of the entire world, so he had the idea of ​​​​revenge on society. Can this be understood? ?”

"Well, toxicology, medicine, and pharmacy students are all taught human ethics, so that the knowledge that should be used to treat diseases, save lives, and resolve cases is not used by people who are doing evil things." Han Su nodded, "This is what your father still wants to do. At that time, the rules set by the Supreme Academy of C Continent are still in use today. If someone has a bad character, the Supreme Academy will not even allow him to enroll. As a prisoner, I can only say that such a person must have encountered something unfair. Or some major change."

"Then continue on. The murderer first stabbed and then killed the two women. First of all, it can be judged from the autopsy results that the murderer was a man and was quite strong, because there were scratches on the wrists and necks of the two female victims. In addition, the forensic doctor also found a hair that did not belong to the deceased from the hair of the deceased. After testing, it was the hair of a black-haired man, and the genetic sequence was that of a yellow race. This overturned all the previous cases. The possibility of one person committing the crime." Qianzhe Mian paused and pointed to one place, "Please look at the pathological section here. The deceased inhaled a large amount of hallucinogens before his death. This is also the key to solving the case. Hallucinogens are the most common drug in Continent F. Strictly controlled drugs, especially such large doses of hallucinogens, cannot be purchased by ordinary people. Therefore, I infer that he is in charge of a drug research institute or laboratory and needs to use a large amount of hallucinogens, otherwise he would not be able to buy them at all. I don’t have the qualifications or the channels to get so much hallucinogens.”

"It makes sense, then we should investigate the major research institutes and laboratories next?" Qin Yelan asked her.

"Stand still for now. After completing the profiling, I plan to go to the crime scene myself to take another look." Qianzhe Mian waved his hand, "The last murderer, let's take a look at the fifth murderer. I prefer to call it a suspense drama and For fans of suspense novels, tying people up and throwing them into the water to drown them is a common killing method in novels. The water can wash away a lot of traces and help him escape, but he forgot one thing."

She zoomed in on the picture: "Everyone, please look here. This is a very classic sailor's knot, and it is a sailor's knot that is not very popular in continent F and even the world."

"Either he has served in the maritime armed forces, or he is a member of a fleet?" Qin Yelan asked.

"Well, this is my guess, and these two cases are the least likely to be indiscriminate killings." Qianzhe Mian pulled out the information of the deceased, "I checked some gossip in the limited time, and two The deceased had dated the same woman successively, and this woman was a married woman."

"Oh?" Qin Yelan looked at her, "Why don't you check this lady's husband now?"

"Yes, that's what I meant." Qian Zhemian held the computer in his hand and typed with one hand, still at a fast speed. After a while, another face appeared on the screen.

"This is the lady's husband." She continued to scroll down.
