ex-husband high energy

I don't know whether the afternoon tea is pleasant or not. Anyway, Levi's is full. As for Zong Ming... Although his expression seems a bit indescribable, the melancholy that has been floating between his brows is like a black cloud blown by the wind. Went a lot.

Levi packed up the lunch box, downloaded a copy of "Language Forensic Science" on his mobile phone and read it slowly while lying on the sofa.Although he studied in kindergarten, his high school grades are actually very good. If he stays in China, he can get into a good university with a tough mother.

It's a pity that his dear mother is completely stocking him, and respecting his ideals is very good.

Zong Ming had already finished playing the bottle, leaned against the head of the bed and closed his eyes for a while, then asked, "Aren't you going to discuss the case with me? Why are you silent?"

"Because you need to rest." Levi said without raising his head, "Aren't you tired after hitting the bottle?"

"I'm an alpha-level mutant." Zong Ming said, "and the venue will be cleared at 07:30."

Levi's put a tab on the e-book and sat up: "What do we do next?"

"Wait for the bureau chief to notify you." Zong Ming said, "I have already written an official email to urge you."

Levi said: "If we have the qualifications now, where should we start this serial disappearance case?"

Zong Ming sat up a little and said, "First of all, there is a problem with your definition of these two cases. The disappearance case and the serial disappearance case are two completely different concepts. In traditional forensic science, there are two methods of analysis. The first is to focus on the victim and the crime scene, and expand the criminal investigation framework from the inside out, because the perpetrators in most criminal cases are people known to the victims, or even acquaintances. Taking homicides as an example, statistics show that about [-]% of them happen in Among relatives and acquaintances."

"What about the remaining [-]%?" Levi asked.

"The remaining [-] percent, more than half of which occurred during the murderer's other crimes, are joint crimes, that is, random and unpremeditated. The most difficult to detect are the remaining less than [-] percent of the cases. It’s a series of crimes.”

"Why?" Levi's was fascinated unconsciously.

"Serial cases, also called serial cases, its biggest feature is that it often happens between the murderer and the victim who are completely unrelated." Zong Ming said, "This is related to the characteristics of the murderer of the serial case. This kind of murderer often chooses the victim. There is no direct motive, such as love, hatred, economic disputes, etc. The core that drives him to commit crimes is his own preference, for example, some people just like to kill people with moles on their faces, or left-handed people, it’s hard to say."

Levi thought thoughtfully: "If you encounter such a murderer, it will be very difficult to expand the criminal investigation framework centered on the victim."

"Yes." Zong Ming said approvingly, "At this time, it is necessary to build a detection framework from the outside to the inside, trying to establish a virtual investigation circle among potential victims, crime scenes and suspects. Specifically, to collect All relevant criminal backgrounds and people with similar psychological problems within the geographic scope of the crime occurred will then be screened through a large amount of information to identify suspects.”

"Oh, I know, I've seen Criminalminds, and that's what profilers do, they infer the profile of the perpetrator based on the characteristics of the victim and the crime scene. Then the police can use these signature characteristics Narrow down the scope of the investigation."

"Hmm." Zong Ming said, "Then the question is, how to determine how many cases are serial cases?"

Reeves thought about it and said, "What do the victims have in common? For example, Buffalo Bill, he would stuff a black moth chrysalis down the victim's throat every time he killed someone."

"This method is called CCA, or Concatenated Case Analysis." Zong Ming taught his rookie assistant very patiently, "We need to analyze the suspect's crime pattern in detail, including the choice of the victim, the characteristics of the scene, witnesses and evidence, etc. etc., and then concatenate the different cases."

With just a few words, Levi's mind immediately felt a lot clearer. Thinking about how he searched like headless flies in the past few days, I was really sorry for Zong Ming's high praise of "You are the one I want"...

"Don't look at me with such eyes that look at God." Zong Ming nodded, "These are the most basic knowledge, which can be found in any textbook. There are so many people graduating from the police school every year, how many of them can become real? A criminal police officer? Some things depend on talent and tenacity. It is easy to make up for theoretical knowledge, but talent is rare."

Levi's said so, and he had a little confidence in his detective career.However, Zong Ming poured cold water on him in the next second: "I'm not talking about you, you are just a little clever, and you are far from the realm of 'talent'."

Levi shrugged indifferently, and said, "At least I still have tenacity."

"..." Zong Ming's expression became indescribable again.

"Keep talking." Levi's was thirsty for knowledge and asked to end the intermission.

"...go get me a glass of water."

"Oh." Only then did Levi realize that the leader had consumed a lot of saliva, so he immediately boiled water, made a cup of Jin Junmei for him and put it on the bedside table, "It's a little hot, you're very thirsty Shall I blow it for you?"

"Are you saying to use your saliva to lower the temperature of this cup of tea?" Zong Ming said seriously, "Although we are already fiancés, we still have to be hygienic!"

Levi's laughed heartlessly: "Then just wait."

Zong Ming hadn't had the desire to hit anyone for many years, but at this moment he wanted to pinch his face very much.

Levi seemed to feel the murderous intent on him, and ran to the nurse's station to ask for two paper cups, poured out a little tea, and let it cool down: "Drink it."

Zong Ming really doesn't know whether to praise him or scold him now. Although it sounds a little hypocritical, this kid really makes people love and hate him!

Zong Ming finally drank half a glass of water, announced the end of the intermission, and continued to start the Baijia Forum: "Let's go back to the original question, how can we determine that these two disappearances are serial cases? How to analyze them as serial cases? "

"From the perspective of the victims, they are members of the same research institute and the same project team, echoing the characteristics of the victims of the series." Levi tried to analyze according to Zong Ming's theory, "From the perspective of the crime scene, they are all They left in a familiar environment, and they all left in a hurry—Guan Jie was doing experiments before he disappeared, and he didn’t even turn off the heater when he left the laboratory, and Han Botao didn’t change his clothes or shoes when he left home—— This shows that before they left, they thought they would come back soon. Judging from the witnesses and evidence...the only evidence I have come into contact with is the surveillance video. Turn a blind eye. Judging from the above analysis, the possibility of a series of cases should be very high, right?"

Zong Ming nodded, and said: "The next step in conventional reconnaissance is to check the social relations of the victims first, to find intersections, and to focus on those colleagues, acquaintances, and relatives who have conflicts of interest with them. , They do research and development for a famous optoelectronic company, so the suspicion of this company's competitors is very high, I guess Captain Liu will visit those companies in a day or two."

"The other thing is to start from the crime scene, look for witnesses and evidence, and deduce their whereabouts." Zong Ming continued, "In addition to surveillance video, the evidence also includes fingerprints and DNA that the suspect may have left at the scene. The possibility of finding these things is very small, and at most the communication records of the victim before his disappearance can be found. Don’t think that the communication records are easy to check. Now that the network communication is developed, it is actually very difficult to track.”

Levi's digested his words, and said: "What you said is starting from the victim and expanding the reconnaissance framework from the inside out, right? Then if it is regarded as a series of cases, it can be pushed in reverse?"

Zong Ming said: "It's good for you to think this way. If we reverse it, we need to profile the suspect, and we must first establish a victim model. If there is another victim, who will it be?"

"Other researchers in the same group?" Levi's was a little dazed.

Zong Ming shook his head and said: "We have too little information at hand, and it is still difficult to make inferences. But the information you provided is very important. If the suspect is a super brain, once the investigation circle is locked, it will be easy to determine the candidate—we You don't even need evidence, just let you stay with him for 48 hours, and you can definitely feel the electrical shock in your brain."

Levi's suddenly realized that he was a humanoid test machine: "Then we'll just do this and wait for the appointment from the bureau? Didn't you say that there are hackers under him, so they can hack Captain Liu's computer?"

"...Don't talk about breaking the law and discipline so openly?" Zong Ming taught him, "This matter is risky. If I am caught by the boss, I will be finished. I guess I will stop my job until the next day." century."

Levi thought about it too, and just wanted to persuade him not to be a monster, and wait for the appointment letter to come out obediently, Zong Ming said again: "So he must find someone who he can't find and can't afford to mess with to do this... ..."

After making trouble for a long time, I still want to be a monster... But Levi thinks that "can't find out" is easy to deal with, a hacker at the level of Omega girl is almost enough, but "can't be messed with" is more difficult-can let The person the deputy director can't afford to offend must be the director and above, right?

However, the director is not crazy enough to want to guard himself and become a hacker, right?

"Who is it?" Levi asked, "The guy who got you a fake arrest warrant last time?"

Zong Ming smiled without saying a word.Levi's became curious and asked, "Who is that person? Is it someone inside you? Or a wild hacker outside?"

"...It's hard to say, this person's identity is quite special, neither inside nor outside, both inside and outside." Zong Ming became more and more arrogant, looked at his watch slowly, and said, "Don't worry so much , Visiting time is coming soon, you are ready to go back, don't forget to feed Patton and Rommel."

Curious about the onset of cancer, Levi wanted to grab his collar and shake him unconscious, and asked, "Who the hell is he? Nobody can afford to mess with him?"

Zong Ming made a "goodbye" gesture and refused to answer.

Levi's wanted to fight again, but the nurse had already come to chase away the people, so he had no choice but to return to Shihu Farm full of regret.
