Criminal Investigation Notes

Su Hui clicked through with his thumb. His WeChat name was "Hui", and he used a photo of Aristotle as his avatar. The cat on the avatar had a pair of big eyes, but his face was full of confusion.

A cat and a dog seem to be a good match, as if they used couple portraits.

The other party was obviously online and sent a message soon.

Not later: "Mr. Su, I took the liberty to ask your contact information from the school. Thank you for your help. We are already looking for the suspect's fingerprints, and we have also obtained information from a buyer. The code name of the person who sold the stump It's called 'The Butcher', and while we haven't found him yet, we're getting closer to the truth."

Lu Junchi thought about it again and again, and felt that he should thank Su Hui. After all, it was because of Su Hui's suggestion that the case was solved so smoothly. If the suspect is found, he should be able to lock him down soon.

Su Hui held the phone, listened to the pattering rain, thought for a while, and sent a message cheekily...

Answer: Captain Lu, are you still working?Is it near the headquarters?

Not too late:?

Such an inquiry seemed a bit too intimate, Su Hui pursed his lips, thinking about what to say next.

He and Lu Junchi are not familiar with each other now, nor are they strangers. The relationship between them seems a little delicate.From what he knew about Lu Junchi, this man was trustworthy and he could ask for help.

Seeing that he didn't reply, Lu Junchi sent another message to ask him.

Not too late: what's wrong?Is there anything I can do for you?

Only then did Su Hui muster up his courage.

Answer: I was outside, it was raining, and I couldn't get a taxi.

Lu Junchi on the other end of the phone sighed, this teacher Su is really troublesome, he has bad eyesight, can't hear clearly, doesn't like to eat on time, and always runs around.

Weiwei: Did you bring an umbrella?

Reply: No.

Lu Junchi raised his forehead.

Weizhi: I'm off work, and I'm at the General Administration, you find a place to shelter from the rain, send me the location, and I'll pick you up.

Re: Sorry to trouble you.

Even if the other party is a stranger who has only met twice, without asking more information, without sarcasm, quickly formulating a plan and implementing it, this is Lu Junchi's way of doing things.

The rain from the sky kept pattering down, and after a while, the ground was soaked, and the tires rolled over and made a sound of water.

It was already 10 minutes later when Lu Junchi drove to find Su Hui. Su Hui couldn't tell where he was, so he walked around for 10 minutes.

The sky was dark, and Lu Junchi went around to the alleyway, only to see Su Hui standing against the wall under a small corner of the eaves.

His whole body was about to melt into the darkness, he looked very thin, the rain had wet the hair on his forehead, his eyes looked wet, and his delicate face became paler, with a fascinating bookish look.

He is not like a university teacher, more like a student.

Lu Junchi honked the horn, and Su Hui walked over and opened the passenger door, and then sat in. His clothes were already mostly wet.

"Here, you can wipe it first." Lu Junchi handed him a box of tissues.

Su replied with a thank you, and then he smelled a burst of fragrance.

After his vision and hearing were not so good, Su Hui's sense of smell became very sensitive. He could tell that it was hamburger and French fries. There was a package of packed food placed between the two of them...

Su Hui suddenly thought that he didn't seem to have eaten much today. It was already past ten o'clock in the evening, and he was a little hungry and his stomach hurt.

But... It's already shameless to ask someone to pick him up in the rain, but now it's a bit too much to eat other people's packed food. His skin is not that thick...

Su Hui didn't say anything, but turned his eyes to this side, glanced at the packed food, swallowed reflexively, and then folded his arms, pressing down on his stomach.

After all, Lu Junchi was the captain of the criminal investigation, and he had already discovered his intentions. Seeing that Su Hui was hesitating there, he dared not say anything, so he took the initiative to ask, "You didn't eat dinner?"

Su Hui responded in a low voice.

With his hands still on the steering wheel, Lu Junchi asked him casually, "Are you busy with work?"

Su Hui hesitated for a while and said, "I forgot..."

"No matter how busy you are, you still need to eat." Lu Junchi said as he turned the steering wheel.

Su Hui didn't know how to answer. If he had known, he would not have looked at the package of food. He lied, "I ate too much at noon, and I haven't been very hungry." He looked at the rain outside the window, but his stomach honestly let out There was a grunt.

In the narrow compartment, it is even more embarrassing...

Su Hui coughed a few times, and Lu Junchi saw that his pale face turned red, and teased him again that he was about to explode.

At a red light, he stuffed the bag of hamburgers and French fries into Su Hui's arms, "Eat it, you're welcome."

Su Hui wanted to eat very much, but still reserved: "This is your dinner...then what should you do?"

Lu Junchi said: "I brought it for my colleagues when I came here, just ask them to order takeaway later."

In fact, Lu Jun has already eaten sooner or later. When he came to pick up Su Hui, he saw a fast food restaurant and thought that he might not have eaten. Team members who worked overtime.

He said that just because he didn't want Su Hui to think that he bought it specially for him.

But Lu Junchi didn't give the food to Su Hui directly. He wanted to give him a little "punishment" so that Teacher Su could remember to eat on time.

Su Hui wiped the rainwater off his face with a paper towel, then brought the burger over, lowered his head and said, "Thank you."

The hamburger in his hand is made of beef and cheese. It is very suitable to replenish energy at this time. Su Hui didn't see him. He was already hungry after running all afternoon. He took out the hamburger and ate it in small bites, thinking while eating. , why I am so embarrassed every time I see Lu Junchi recently.

Lu Junchi watched him eating the hamburger. He had just chatted with Su Hui on WeChat, and now he had the feeling that he had picked up a wet and hungry little wild cat.

The food quickly soothed the stomach and warmed up the body, and all the depression was swept away.

They drove out of that area, and Lu Junchi asked, "Where does your family live?"

Su reported an address.

Lu Junchi turned up the air conditioner, set up the navigation, and drove in that direction.

After Su Hui finished eating the hamburger, he carefully collected all the rubbish, slipped Lu Junchi over at night, and then ate his dinner, Su Hui looked at Lu Junchi and said, "I'm sorry this time, I seem to owe you money again." You are a favor."

Lu Junchi: "It's okay, you gave me advice on the case before, and it has helped me a lot."

Su Hui said in a low voice: "Those are just casual mentions, not helpful."

Hearing what he said, Lu Junchi brought the topic to the case. He always felt that Su Hui was hesitant to speak every time, and he wanted to get more information from him.

"Mr. Su, after we talked with you last time, we went to search for the garbage in the coffee shop that fit the time. We have classified them, but there are many fingerprints on them, and the pollution is a bit serious. Those fingerprints can be used as comparison fingerprints. , is not enough to check in the fingerprint database.”

That is to say, if they now have a suspect and get their fingerprints, they can use the fingerprints on those coffee cups to confirm that the suspect was in the coffee shop and help them identify the perpetrator.

But those are incomplete fingerprints with large errors, which cannot allow them to directly find the murderer in the fingerprint library of the ID card.

Lu Junchi concluded: "We now have some information about the murderer, such as blurred images, incomplete fingerprints, and shopping habits, but we still haven't been able to find him. He was very careful not to reveal his vehicle information. We found The network numbers are all registered from abroad. I still remember you said that after we found those stumps, the murderer would commit the crime very quickly."

Ever since he took this case, Lu Junchi felt inexplicably uneasy, as if a sword was hanging over his head.

The suggestions Su Hui gave him greatly accelerated their speed of solving the case, but these were not enough. They had to catch him before the new victim appeared.

Su Hui thought about it: "The suspect now knows that the police are arresting him, and he may change his usual way of doing things."

"In other words, he might temporarily give up women's clothing?" Lu Junchi frowned.

If the suspect continued to wear women's clothing, he would actually have a better chance of being caught, but once he gave up this behavior pattern and became like a normal person, it would be harder for them to catch him.

Su replied: "The current information cannot be confirmed yet."

Lu Junchi was silent for a moment and said, "This murderer always reminds me of Edward Gain."

Known as the small-town killer, Edward has been adapted into many films, the most famous of which are Buffalo Bill in "The Silence of the Lambs" and "The Texas Chainsaw Massacre".

That's a psycho who digs up corpses from graves, and what he does is beyond what people call the bottom line.

Lu Junchi felt that the murderer in front of him had some of the same characteristics as Edward, including women's clothing and the use of corpses.

Su Hui shook his head: "No, they are not exactly the same. When you face these people, you can't just look at their symptoms, but look at their motives and the nature of their crimes. The police will enter into a habitual misunderstanding, that is, use Normal thinking and known common sense to infer the murderer, and trying to link the criminal behavior with known cases, will only make you farther and farther away from the real criminal."

Lu Junchi humbly asked for advice: "Then what are their similarities and differences?"

The rain outside the window has been rustling, Su Hui's voice is low and hoarse, but his face is calm and rational: "Edward's IQ is very low, he has never really been with a woman in his life, and his mother is the only woman he knows. He has never really integrated into human society, he is a mental patient."

"But the murderer in front of us, he can do a good job of camouflage, he can adapt and integrate into human society, he doesn't like corruption, so he will think of various ways to keep the stump fresh. He is meticulous and has a plan , premeditated, meticulous, every step of his is not superfluous, very purposeful..."

Su Hui's eyes narrowed slightly, and he looked at the dimly shaking wipers in front of him, "He will try his best to coexist peacefully with his special hobbies, and sell his stumps to weaken his sense of guilt and obtain money. He has enough disguise, and he may even With normal social skills and excellent communication skills, it will be more difficult for you to catch him than the kind of murderer who is out of tune with the crowd."

"However, I think he may be the same as Edward in one point. I also feel some traits of a perverted serial killer in him. I think his choice of female coffee shop clerks may have something to do with his mother. He His mother may be strong, and he may live in the shadow of his mother."

Su Hui began to analyze involuntarily, and then he suddenly stopped. He suddenly felt that this kind of discussion had happened at some point, and this scene made him feel familiar...

He had long vowed not to conduct profiling analysis without evidence, but when Lu Junchi asked, he continued naturally. There was a sense of tacit understanding between them chatting, which made Su Hui a little scared...

Lu Junchi didn't notice his strangeness, and said, "I think your analysis is very good, and it will be very helpful for our next work."

Su Hui received the sudden praise, and he was taken aback for a moment.

It seems that it has been a long time, he has not been close to these police officers and these cases.

Since he came to the Chinese Police to teach, he has not gone out for a long period of time, does not go shopping, does not party, and does not participate in any social gatherings.

He imprisoned himself in the campus, only facing those students.

There was a moment of silence in the carriage, and then Su Hui sighed softly, "Why are there so many monsters in this city..."

Lu Junchi speaks with numbers: "Take the work summary of the city's public security system last year as an example. There were nearly 25 criminal cases in Huadu. There are 2500 detention centers in the city, which are nearly full all year round. Among them, those who are the worst are cases that cannot be solved for a while. , will belong to the serious crime team. With a population of [-] million, it is not surprising that there are a few perverts."

Even after receiving this case, Lu Junchi only refreshed his three views at the beginning, but soon he got used to it, went all out, and put all his attention on the arrest.

Su Hui also knew that cases with less than two victims, or independent cases with a clear murderer, did not fall under the jurisdiction of the serious crime team.The case that Lu Junchi took over must be the most distorted, complicated and difficult case in the whole city.

Tens of thousands of criminal cases may have tens of thousands of victims.

This is not counting so many missing, or unknown cases.

It turns out that in this seemingly peaceful city, so many people are struggling and dying...

Except for those ordinary criminal cases, the police, especially the serious crime team, will inevitably face a kind of person-serial murderers.

They are extremely ferocious, addicted to killing, and the matter of killing is constantly churning in their minds. They don't seek money, just to enjoy the thrill of killing.

Those who are sinful, are like cancer cells that grow wrongly, but when there is no attack, you cannot guard against it and better prevent it.

You only have to use the fastest speed to find them, execute them, and prevent the spread of killing after the crimes have occurred.
