Criminal Investigation Notes

Su Hui's words were completely different from the answer Lu Junchi expected.

Lu Junchi looked at the man in front of him suspiciously.

He didn't know what Su Hui had learned and experienced in the past. In Su Hui's words, he vaguely felt that he seemed to have some slight resistance to the portrait of criminal psychology.

Lu Junchi regretted bringing up this topic at this time, but he still wanted to justify the name of this criminal investigation method: "Mr. Su, you have been doing academia, you may not be clear, the criminal psychology portrait is of great practical significance to our police, and it has also been given to us. great help."

Su Hui shook his head with a serious and serious expression: "In a short period of time, I can't explain my point of view clearly. Profiling is to use the thinking of the profiler to infer the thinking of the murderer. Different profilers will draw different conclusions, among which A lot of it will be useless information, and sometimes even misinformation.”

Lu Junchi tried his best to argue with him calmly: "Mr. Su shouldn't be so veiled. I have personally witnessed the magic of profiling. A good profiler is like a key that can solve a case."

"No one can guarantee that the result of the profile is 100% correct. With limited knowledge, the correctness of the profile is even more difficult to guarantee, and the wrong profile will lead you into confusion." Su Hui picked up the water glass and took a sip Shui, then put the cup down and asked, "Captain Lu, have you contacted the behavior analysis team that was called off?"

Lu Jun nodded late.

Su Hui put his back on the back of the sofa and continued: "The police in many cities used to have profile groups, but they were called differently, some were called criminal psychology research rooms, and some were called behavior analysis groups. However, crime In the practice of psychological portraits, how to combine theory with practice has always been a difficult point. Huadu's behavior analysis team helped the police detect some cases at that time, but it also exposed big problems. Personally, that It's not a bad thing that the behavioral analysis team was shut down."

Maybe it was because Su Hui was a teacher. He spoke in a polite, clear and logical tone. His voice was a little hoarse, but there was an unquestionable paranoia in his words.

Lu Junchi knew that after the disbandment of the behavior analysis group, some conservative people in the police also had this idea.

But he couldn't imagine that the teacher of criminal sociology in front of him was so conservative.

He knew that he was here to ask Director Liao for advice, but he kept pouring cold water on him.

More importantly, what Su Hui is saying lightly is that some people have been exploring and striving for their careers all their lives...

Seeing that Lu Junchi's brows were getting deeper and deeper, Su Hui gathered his words back a little: "Captain Lu, don't be angry, the profile can still be used as a reference within a certain range, but compared to it, I think the police need more evidence and practical facts. Case-solving ideas.”

This sentence is fairly pertinent. Lu Junchi felt that Su Hui probably had some prejudice against the criminal psychology profile. And this teacher Su didn't understand the predicament he was facing now. If there were other directions of investigation, he didn't have to come here.

Thinking of this, Lu Junchi pushed the document forward: "Mr. Su, if he has signed the confidentiality agreement between the General Administration and the college, can also understand the case we are encountering now, and give pointers on how to find practical ideas for solving the case."

Su Hui didn't hesitate, picked up the information in front of him and carefully turned it over.

Lu Junchi introduced: "We found those stumps in several scrap cars. The murderer was very careful, leaving no evidence, let alone relevant witnesses, and the identity of the victim has not been determined."

"So, do you still have feet?" Su Hui blinked, then explained, "I saw a post on the Internet before, but it only said that I found a pair of severed hands..."

"The media's understanding is not comprehensive." Lu Junchi said, "At present, these stumps belong to different victims."

Su Hui took those photos over and looked at them one by one, each of which paused for a moment in front of his eyes, as if the camera was focusing, when he saw the ambient photos, his expression changed slightly: "The murderer made full use of the city's waste. Car space, have you done an analysis and investigation?"

"The routine has been done. In addition, a micro-material identification has been applied for the residual limb, and I hope to find some clues."

Su Hui listened quietly, then nodded: "Victim research, the more we understand the victim, the better we understand the murderer. This is an idea..." Then he asked again, "Has the white powder been tested?"

"A mixture of boric acid, alum, and camphor, readily available."

Su replayed the document and said, "Rough preservative powder."

Then he lined up the photos of the three hands and feet with his slender fingers and looked down carefully.

As can be seen from the photos, these stumps have been stored for different periods of time and have different degrees of decay.

Those junk cars... what do they represent?

The two suddenly didn't speak, and the room was awkwardly quiet.

Lu Junchi felt that it seemed that Teacher Su was helpless. He had already made an appointment with Director Liao. If he couldn't analyze it, he would be embarrassed.

He was thinking about how to end the conversation, and then he heard Su Hui ask, "You said, the cars where the stumps were found are very clean?"

Lu Jun gave a late hum.

Su Hui frowned and thought about it for a while. He seemed to think that this was a bit unreasonable. He thought for a while, and then looked at a few other photos. Those scrap cars were grouped together...

Su Hui's brows stretched out: "Although I can't help Captain Lu with the profile, I still hope to give you some help."

Lu Jun paused and looked sideways at the man's beautiful eyes. In the sunlight, his eyelashes were distinct.

Su Hui squinted his eyes slightly, and continued with his right hand swirling the scepter: "I found that you found those stumps, and also found a few scrap cars as 'showrooms', but you didn't seem to check the other scraps at the scene. Vehicles. I suggest that you bring your physical evidence and carefully search for all the scrap cars in the same location."

Urban junk cars are also dubbed zombie cars. Many car owners would rather throw the car away than send it to the DMV because of its age and incomplete procedures.

Like the Broken Window Theory, those junk cars often don't appear alone. As long as one person abandons the car in one place, new junk cars will appear soon, as if they themselves will multiply in the city.

The same is true for those several sites. At each site, there are several scrap cars parked around, and the police force problem, they only found one of them.

What Su Hui said was the place where their physical evidence had not been investigated, and it was also a blind spot for the police.

Listening to Su Hui's voice, Lu Junchi nodded thoughtfully, and then he said, "Thank you, Mr. Su, I will ask my colleagues to check these cars again and collect all the evidence."

Su Hui nodded: "You have to hurry up, the murderer may commit another crime in the near future."

As the words were said, the door of the office was opened, and Director Liao walked in.

Director Liao's full name is Liao Changen, and he is in his 40s this year. He wears glasses and is an amiable looking middle-aged man. When he laughs, he has a dimple on one side. When he sees Su Hui and Lu Junchi, he smiles and says, "You two have been waiting for a long time. After class, there are students Asked me a few questions."

Lu Jun said lately, "It's okay, I just waited for a while."

Su Hui also got up: "Director Liao, I'll get the stamped document."

"Mr. Su, wait a moment, I'll take it out for you right away." Director Liao waved his hand inward, "Captain Lu, you and I go in and talk."

Liao Changen flipped over on the table inside, took out a clip, took out a certificate with a red stamp, walked out and handed it to Su Hui: "Mr. Su, what you want."

Su Hui reached out to pick it up.

Director Liao was not in a hurry to give it to him, he withdrew his hand and warned: "Mr. Su, it's not me, this is a bit dangerous, even if you are doing research, you don't have to work so hard, let's take it seriously. , things are a bit out of bounds, our Chinese police are at most an auxiliary department of the police station."

Su Hui's eyes were a little pale under the sun. He turned his head and frowned slightly, as if he didn't hear clearly: "What?"

Director Liao wanted to beat the disobedient teacher, but now he was suffocated, and he couldn't tell whether Su Hui did it on purpose or if he really didn't hear it clearly.

He didn't want to be Lu Junchi's face like a deaf person, and he didn't have the patience to repeat that long list of words again. Finally gave the things to Su Hui: "I said... Forget it, Mr. Su, take care of your own safety."

Su Hui took it over and thanked him, folded a few folds and put them in his trouser pocket, then walked out the door.

Lu Junchi turned his head to look at this teacher Su. He was still talking to him just now, but his body turned to the right involuntarily. It may be that the hearing of the right ear is better than that of the left.

From the previous reactions of Assistant Director Liao and Director Liao, it can also be seen that there are some problems with his hearing.

Only Lu Junchi and Liao Changen were left in the office for a while, and Lu Junchi started talking: "Director Liao, this Teacher Su..."

Liao Changen smiled wryly without concealment: "It's a bit strange, right? It looks quite docile, but..." Director Liao hesitated for a while, probably thinking that Lu Junchi was an irrelevant outsider, and couldn't help but complain a few words.

"Today's young teachers really don't understand the world, their qualifications are not high, but their eyes see the sky. They don't care about teaching, and they use some crooked brains every day. To be honest, I have taught for many years and have never met such a teacher... Recently He had to go to Baihushan Prison again, saying that he was going to do a dissertation project, and he didn’t teach criminal psychology. Isn’t this asking for danger? I kindly reminded him, but he pretended to be deaf and dumb here…” Director Liao let out a long sigh.

When Lu Jun heard this, he was a little surprised. He didn't expect Director Liao's evaluation of this teacher Su, and he didn't expect that Su Hui was going to Baihushan Prison, where there were always some serious criminals. He himself has sent a lot of them, the light ones will start at least five years, and the heavy ones will be executed.

The scene was a little embarrassing for a while, and Lu Junchi said, "Perhaps capable people are generally a little arrogant."

"Ha, ability?" Director Liao chuckled, "I hope he will have at least one paper published in the core journals this year. Otherwise, the summer teachers' debriefing may not be easy. He is not in a hurry, I, the director, have to do it. Worry about him."

The Chinese police always have requirements for teachers' teaching and research, and they will be assessed every other year. The rigid rule is to publish three regular periodicals every two years. core journals.

There are not many professional journals in this area in Huaxia. There are nine in total, which are also called nine journals. In order to appear in the nine magazines, the teachers sharpened their heads and broke their heads.

As far as Director Liao knew, the name Su Hui had never appeared in those publications.

Lu Junchi heard from Director Liao's tone of schadenfreude. It seems that this school is not a pure land, and there are as many struggles as there should be.

"Stop talking about that." Director Liao took off his coat and hung it on the back of the swivel chair. Then he turned around and said, "Xiao Zhang told me, Captain Lu, please show me the information."

Lu Junchi handed over the information in his hand, but he was still thinking about what Mr. Su said before, and he was a little worried about the safety of Mr. Su's line.

Director Liao put on his glasses and looked at the documents, his expression became more and more serious...

An hour later, when Lu Junchi came out of Director Liao's office, he was hungry. He unlocked the car and received a call from Qiao Ze.

Qiao Ze's voice came very loudly: "Team Army, I'm investigating at the scene with the physical evidence."

Then he lowered his voice, "I've already checked three scrap cars, and the people in the inventory said they didn't find anything new, it's all natural information left by the car owner, I'm a little impatient..."

Physical identification finds information such as fingerprints, bloodstains, footprints, etc. This is both a personal labor and a technical task.

It used to be very troublesome to check one car, but now I suddenly have to check several more cars, and I don't know what to check. It is natural to have complaints.

Lu Jun was late, and Qiao Ze was too young to hold back.

"Is Lao Han leading the team?"

Jose hummed.

Lu Junchi told Qiao Ze: "You try to coax them, buy them some drinks, tobacco and alcohol or something, or have a meal together at noon, and reimburse you later."

Qiao Ze took a few steps to the side, lowered his voice and asked again, "What is the next thing to ask for... Army Corps, this is the profile result obtained from Director Liao? Are you sure you can find it?"

What Qiao Ze is most afraid of is to return without success...

"No, it was a suggestion from a criminal sociology teacher..." Lu Junchi suddenly thought that the teacher Su didn't explain the reason and reason.

"Captain Lu, where is Director Liao, is there any helpful information?" Qiao Ze asked.

Lu Junchi was slightly disappointed by the conversation just now: "I had a careful chat with Director Liao, and felt that some of his suggestions were a bit idealistic and difficult to implement."

The conversation just now was very long, but there were not many useful results. Lu Junchi had already deduced many things that Director Liao said.

Director Liao also analyzed that the murderer may have been abused and bullied in his childhood, and he may have an unhappy family and like to be alone. This sounds reasonable, but it does not allow the police to extract effective information, let alone help them catch the murderer.

Others include some data on the proportion of such people, related academic papers…

After hearing that, Lu Junchi became more and more helpless. Those data could not help them filter this man out of millions of school-age men.

At the end of the topic, Director Liao, seemingly unintentionally, mentioned the candidate for their major crime team consultant...

Although Lu Junchi respected Director Liao, he felt that Director Liao was not a good choice, so he quickly changed the topic.

Just as he was recalling this, Lu Junchi heard the voice of the book from the mobile phone: "Officer Qiao! It's almost the last car that hasn't been checked."

Qiao Ze hurriedly said: "Han Tou has worked hard, I'll come over immediately!"

Lu Jun thought about it for a while, and felt more and more that his previous decision was a bit arbitrary.

If he couldn't find anything this time, everyone's inspection was in the wrong direction, and he reckoned that he would have to go to the inspection center to make amends.

According to normal thinking, it is not easy to find one with something in a pile of junk cars. How could the murderer have something to do with other cars? But just now, he just had no reason to believe what Teacher Su said...

Facing the teacher Su, Lu Junchi had an inexplicable sense of familiarity and trust. He felt that what the person in front of him said must have a reason, and it makes sense...

Lu Junchi was in a daze when suddenly he heard a loud noise on the phone, Qiao Ze hurriedly said, "Captain Lu, I'll talk to you later..."

The noise on the opposite side suddenly became louder, but it was vague, and it was impossible to hear what was being discussed.

Lu Jun faintly felt that something was wrong, he became nervous, sat up straight, and clenched the phone in his hand.

Then he heard Qiao Ze's voice trembling with excitement, and there was disbelief in his tone.

"Head! We found a lot of marks on the last car!"

It turned out that Teacher Su's suggestion was correct.

The scrap car I found before is a showroom, and the one next to it is a playground...
