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 big eyes, but his face was full of confusion.

One cat and one dog, it looks like a good match, like a couple's portrait.

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

Weiwei: "Mr. Su, I took the liberty to ask for your contact information from the school. Thanks for your help, we are already looking for the fingerprints of the suspect, and we have also obtained information from a buyer, the code name of the person who sold the stump. Called 'The Butcher,' and we haven't found him yet, but 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 investigation of the case could be so smooth. If the suspect is found, it should be able to be locked quickly.

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

Re: Captain Lu, are you still working? Is it near the main office?

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 neither familiar nor strangers, and the relationship between them seems to be a little delicate. From what he knew about Lu Junchi, this man could be trusted and he could ask for help.

Seeing that he hadn't replied, Lu Junchi sent another message and took the initiative to ask him.

Not late: what's wrong? Is there anything I can help with?

Only then did Su Hui summon up his courage.

Re: I'm outside, it's raining, and I can't get a car.

Lu Jun on the other end of the phone let out a sigh of relief. This teacher Su is really worrying. He has bad eyes, can't hear well, doesn't like to eat on time, and is always running around.

Not late: Have you brought an umbrella?

Reply: No.

Lu Jun held his forehead late.

Weiwei: I've already got off work, and I'm at the General Administration. Find a place to shelter from the rain, send me the location, and I'll pick you up.

Reply: Excuse me.

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

The rain in the sky has been pattering non-stop, and after a while, the ground is soaked wet, and the tires press and make bursts of water.

Thirty minutes later, when Lu Junchi drove to find Su Hui, Su Hui couldn't tell where he was, so he walked around the neighborhood for ten minutes.

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

He was about to melt into the darkness, looking very thin, the rain had wet the hair on his forehead, his eyes looked wet, and his delicate face became whiter and whiter, with a fascinating bookish air.

He is less like a university teacher, more like a student.

Lu Junchi honked the horn, Su Hui walked over to open the passenger's door, and then sat in, most of his clothes were already wet.

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

Su thanked him back, and then he smelled a burst of aroma.

After the sight and hearing were not very good, Su Hui's sense of smell became very sensitive. He could distinguish the taste of hamburgers and fries, and a package of food was placed between the two...

Su Hui suddenly thought that he didn't seem to eat much today. It was already past ten o'clock in the evening, and he was a little hungry and had a stomachache.

But... it's shameless to have someone come to pick him up in the rain, and now it's a bit too much to eat other people's packaged food. His face is not that thick yet...

Su Hui didn't say anything. He rolled his eyes to this side, swept over the packaged food, swallowed conditionedly, and then crossed his arms to press his stomach.

Lu Junchi was a criminal investigation team leader, and he had already discovered his intentions. Seeing that Su Hui was hesitant to say anything, he took the initiative to ask, "You didn't have dinner?"

Su Hui responded in a low voice.

Lu Junchi's hand was still on the steering wheel, and he seemed to ask him casually, "Are you busy at work?"

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

"No matter how busy you are, you still have to eat." Lu Junchi said and turned the steering wheel.

Su Hui didn't know how to answer. He would have stopped looking at the package of food if he knew it earlier. He lied, "I ate a lot at noon, and I haven't been very hungry." He looked at the rain outside the window, but his stomach honestly said A grunt sounded.

It's even more embarrassing in the cramped car...

Su Hui coughed a few times, and Lu Junchi saw his pale face turn red.

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 too much, but he still said reservedly: "This is your dinner... Then what are you going to do?"

Lu Jun said lately, "I brought it to my colleagues by the way when I came over. I'll just ask them to order takeout."

In fact, Lu Jun had 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 and bought it on the way. If Su Hui didn't eat, he would be prepared to take advantage of the few members of the team. Players working overtime.

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

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

Su Hui wiped the rain on his face with a tissue, then brought the hamburger over, lowered his head and said, "Thank you."

The hamburger in his hand is made of beef cheese, which is very suitable for replenishing energy at this time. Su Hui did not see the outside world. He was already hungry after running all afternoon. He took out the hamburger and ate it in small bites, thinking while eating. , why is it so embarrassing every time I see Lu Junchi recently.

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

The food quickly soothed the stomach, and even the body warmed up, and those depressions were swept away.

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

Su returned 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 put away all the rubbish, slipped Lu Junchi over at night, and then ate someone's dinner, Su Hui looked at Lu Junchi and said, "I'm sorry this time, I seem to owe it again. You are alone."

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 to mention helping."

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

"Mr. Su, after chatting with you last time, we went to the coffee shop to find the garbage that matches the time. It has been classified, but there are many fingerprints on it, and the pollution is a bit serious. Those fingerprints can be used as comparison fingerprints. , it is not enough to check in the fingerprint database."

That is, if they now have a suspect, 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, and the error is large, and they cannot directly find the murderer in the fingerprint database 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 and didn't reveal his vehicle information. We found him. The Internet numbers are all registered from abroad. I remember you said that after we found those stumps, the murderer would commit the crime soon."

Since taking this case, Lu Junchi has been inexplicably uneasy, feeling as if a sword is hanging over his head.

The advice 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 for a moment: "The suspect now knows that the police are arresting him, and he may change his usual way of doing things."

"That is, he might give up women's clothing temporarily?" Lu Junchi frowned.

If the suspect continues to wear women's clothing, he actually has a better chance of being arrested, but once he abandons this pattern of behavior and becomes like a normal person, it will be more difficult for them to catch him.

Su replied: "The current information is still uncertain."

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

Known as the small-town hitman, Edward has been adapted into many films, most notably Buffalo Bill in The Silence of the Lambs and The Texas Chainsaw Massacre.

That's a pervert who digs 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's, 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 characteristics, but at their motives and the nature of the crime. The police will enter a habitual misunderstanding, which is to use Using normal thinking and known common sense to infer the perpetrator, and trying to connect criminal behavior with known cases, will only make you farther and farther away from the real perpetrator."

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

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

"But the murderer in front of us, he can do good disguise, 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 planned. , premeditated and meticulous, every step of his is not superfluous, and the purpose is very strong..."

Su Hui's eyes narrowed slightly, looking at the swaying wipers in front of him, "He will try to coexist peacefully with his special hobby, weaken his guilt by selling stumps, and get money, he has enough camouflage, and even he may With normal social interaction and excellent communication skills, it will be more difficult for you to catch him than a murderer who is out of tune with the crowd."

"However, I think he may have something in common with Edward, and I also feel some characteristics of a perverted serial killer in him. I think his choice of female coffee shop clerk is probably related to his mother. His mother may be powerful, and he may live in her shadow."

Su Hui began to analyze involuntarily, and then he suddenly stopped. He suddenly felt that this discussion seemed to have taken place at some time. This scene made him feel familiar...

He had long vowed not to conduct unsubstantiated profiling analysis, but as soon as Lu Jun asked, he naturally continued. There was a sense of tacit understanding between them chatting, which made Su Hui a little scared...

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

Su Hui was suddenly praised, and he was stunned for a moment.

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

Since he came to teach at the Chinese police, he has not gone out, gone shopping, gathered, or participated in any entertainment for a long time.

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

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

Lu Junchi spoke with numbers: "Take the summary of the work of the city's public security system last year, there were nearly 10,000 criminal cases in Huadu, and 25 detention centers in the city are nearly full all the year round. The worst of them are cases that cannot be solved temporarily. , will belong to the serious crime team. With a population of 25 million, it is not surprising that there are several perversions."

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

Su Hui also knew that cases with fewer than two victims, or independent cases with a clear murderer, were not under the jurisdiction of the serious crime team. The case that Lu Junchi took over must be the most twisted, complicated, and troublesome in the entire city.

There may be tens of thousands of victims in tens of thousands of criminal cases.

And that's not counting so many missing, or unknown cases.

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

In addition to those ordinary criminal cases, the police, especially the serious crime team, will inevitably face a type of person - a serial murderer.

They are extremely cruel and addicted to killing. Their minds keep churning about killing. They don't make money, they just want to enjoy the thrill of killing.

Those who are evil are like cancer cells that grow wrong, but when there is no attack, you cannot prevent it and prevent it better.

You can only use the fastest speed after the crime has happened, find them, execute them, and stop the spread of the killings.
