Zhou Li, a psychopath, cut off Zheng Pingping's head.

At this point in the case, the chain of evidence cannot be closed, and it seems to have entered a dead end.

The murder weapon that slits the throat, the phone of the mysterious man, the strange footprint number three, the pattern of the altar at the scene of the crime, the missing internal organs. None of these doubts have been resolved, and there are no clues at all.

All this tells me that things are far from over, but the truth seems to be slowly emerging.

Zhou Li has been criminally detained, and he needs to be judged on his capacity for criminal responsibility as a mentally ill person.

In order to speed up the progress of solving the case, we decided to divide the troops into two ways, re-investigate the crime scene, further autopsy, and reintegrate the existing clues to investigate.

This is a planned homicide, a high-IQ crime. And what we know about the real murderer is only a strange footprint, which is obviously unacceptable.

Li Meng and I decided to continue the investigation of Zheng Pingping's company, and the first object of the investigation was Liu Yan, the employee who had been cut off in the factory accident that year.

Liu Yan's home is not difficult to find, in a relocation building community.

Ringing the doorbell, the door was opened by a man, he was in his thirties, short and thin, he looked very sven, he looked well-read with glasses, he was wearing a dark blue T-shirt, gray sweatpants, and flip-flops barefoot.

He is Liu Yan, and from the moment I met him, I felt that he was completely in line with the criminal profile that Li Meng had made before.

"Who are the two?"

Liu Yan looked at us and asked in a magnetic voice.

"Police."

I showed him my ID and locked my eyes on him, observing any changes in his micro-expressions. The knee-jerk reaction of an ordinary person and a criminal suspect to the word police must be different, even if he has a perfect lie. Micro-expression is a science, and it is a unique skill of a senior criminal policeman.

Liu Yan was a little stunned, and then held his glasses with the back of his hand: "Is there something wrong with the two police officers?" ”

The hands were severely skeletal deformities, and the scars on the backs of the hands seemed to be the marks left by steel nails during the treatment of fractures.

"What's your name?" Li Meng suddenly asked, she also felt that Liu Yan's appearance was completely in line with her criminal profile.

"My name is Liu Yan."

Hearing the name Liu Yan, Li Meng was even more determined that he was the murderer of this murder case. She frowned and asked very seriously, "Do you know Zheng Ping?" ”

"Zheng level? Acquaintance, he is my former boss. ”

Li Meng showed a subtle smile and reached for his waist, ready to take the handcuffs to control the suspect.

Crime profiling can only be used as a skill to assist in solving the case, not as direct evidence, and the evidence we currently have is only a strange footprint, the evidence is insufficient, even if he is arrested, he can only be imprisoned for 48 hours at most.

I hurriedly stepped forward and interrupted Li Meng's next move: "Can we go in and talk?" ”

The sudden arrival of two policemen made Liu Yan a little confused, and after he was stunned for a few seconds, he nodded solemnly, turned sideways and let us in.

Walking through the door, there was a huge living room in front of us, the food on the innermost table was still steaming, and a woman was standing at the table at a loss and looking at us.

"Eating soon, right?" I smiled.

"Well, I'm eating." Liu Yan also smiled.

"Then you eat first, let's talk slowly after eating, we don't have anything to do this time, just ask you about the establishment of Zheng Pingxin's company."

As soon as I finished speaking, Li Meng looked at me with a very surprised gaze. The police came to investigate the suspect, but they were not in a hurry? Shouldn't it be brought back to the Interpol team for interrogation according to the procedure?

She is a highly educated returnee, and her theoretical knowledge is undoubted, but she still has little time to work at the grassroots level, and the police handle cases to find clues in countless details, not to complete the detection procedure step by step like the theory in the book.

"The two police officers haven't eaten yet, let's eat some together, my daughter-in-law's cooking skills are a must." Liu Yan politely extended an invitation to dine with us.

"Thanks, we've eaten." I smiled and politely declined.

"Sit down, those two officers, I'll be right away."

As soon as Liu Yan finished speaking, his wife had already poured two cups of warm water for us and put them on the coffee table, judging from the eyes she kept throwing to Liu Yan for help, she was very panicked in her heart. On the contrary, Liu Yan behaved very naturally.

But it's too natural.

"Can I just take a look?"

"Officer, please."

Liu Yan returned to the table and sat down, and continued to eat very naturally, as if the two policemen had been his friends for many years. Liu Yan's wife stopped talking, mechanically eating the rice in the bowl, forgetting to eat the vegetables.

Li Meng was a little impatient, and he didn't know what medicine I was selling in the gourd, so he sat directly on the sofa.

I walked around the living room casually, observing Liu Yan's every move from time to time, his hands holding the dishes and chopsticks were shaking, it was an uncontrollable muscle shaking, like Parkinson's.

Although he fits the criminal profile made by Li Meng, how can such a person with a thin stature, a weak Wenwen and a disabled hand be an opponent of Zheng Ping. Judging from Zheng's physical fitness, he can pick Liu Yan up with one hand.

Ren Qiushi of the forensic department said that Zheng Pingping's throat was cut, and it was a fatal blow, and the angle was from top to bottom. The incision on the front chest is even smoother, how can he, a person who shakes with dishes and chopsticks, hold a knife to remove the internal organs? Even if Liu Yan had a motive to kill, he had no ability to kill.

After walking a few steps, I saw a family photo of three people on the TV stand.

"Didn't the kid come back for dinner?" I asked him casually.

"Well, the child lives in school and comes back after the holidays."

Hearing my question, Liu Yan immediately put down the dishes and chopsticks, swallowed the food in his mouth, turned slightly sideways, and answered in front of me.

Seeing his polite appearance, I was a little embarrassed to disturb him eating.

When I put the picture back, I found that there were still two statues of gods on the TV stand.

The god is like a blue-faced fang, hideous face, and not kind at all. These are two Hindu gods who have known about transnational smuggling cases before.

One is a blue idol of Lord Shiva, a symbol of destruction and rebirth.

One is the black goddess Kali, symbolizing killing, she uses a scythe to cut off the head of the demon, but every drop of the demon's blood will come back to life on the ground, so the goddess Kali catches the blood dripping from the demon's head with a plate. While defeating the demons, she will become bloodthirsty, and the goddess Kali trampled on the earth frantically, and all beings were devastated, so Lord Shiva lay down under the goddess Kali and let her trample herself to calm the bloodthirsty anger.

A little Hindu allusion, quite interesting.

Turning away, I walked to the bedroom, which was a more intimate place, and I took a brief look and didn't stop for long. Next door is the second bedroom, which should be the child's room, and in the corner is a study desk, and the desktop computer on it is still working, staying in a PS interface, which is an interior design drawing that has not yet been completed.

"Officer."

Liu Yan's voice came from behind him, he was already sitting in front of the sofa, and his wife was cleaning up the dining table.

"How long have you been working for Zheng Pingping's construction company?" I asked straight to the point.

Liu Yan's gaze drifted to the ceiling, and when people carefully recalled a past, their eyes would subconsciously look up or down.

"Six or seven years......," he recalled, and affirmed, "six and a half years." ”

"What are you responsible for?" I paused for a few seconds before moving on to the next question.

"Responsible for the decoration design."

"You have such a high education, your position in the company is not low." I quipped casually.

Hearing me say this, he waved his hand again and again, and smiled modestly: "The police officer said that I was joking, what kind of high education am I, I am an ordinary undergraduate graduate, because I am proficient in computers, I have worked in the company for several years, and I have barely been promoted to a director." ”

I smiled, paused for a few more seconds, and asked him, pretending to be surprised, "What's wrong with your hand?" ”

Hearing me ask about his hands, he subconsciously bent over, his hands stiffly clasped together on the other side of his body, as if he was very unconfident in his hands and wanted to hide them.

He took a deep breath and said slowly: "I went to the construction site again, the scaffolding collapsed, the wall fell and crushed me underneath, and my hands were crushed and fractured......"

He was silent for a long time and sighed: "It's good that I can pick up a life, and now every day of my life is picked up by me." ”

"Did the company compensate you?" I nodded, expressing pity and sympathy.

"Alas, the compensation is compensation, but it is a little late, if he could have compensated earlier, my hands would not be what they are now. After the accident, it was a co-worker who sent me to the hospital, and Zheng Pingping only paid a little for the hospitalization, and he didn't even show his face. The cause of the accident was the construction quality problem, Zheng Ping saw that the situation had become bigger, he couldn't control it, and he ran away with money, and I missed the best medical rehabilitation period because I didn't have enough surgery costs, and my hands were like this. He smiled wryly. This was the darkest period of his life, and now he can tell me about this past in a flat way, which shows that he has come out of the haze.

Liu Yan's answer so far is consistent with the results of our investigation, and he is not lying.

But I always felt that something was wrong, and the more seamless the answer, the more strange it became.

It was a well-planned homicide, a high-IQ crime that bordered on perfection. If it weren't for that strange footprint left at the scene, we wouldn't know anything about the murderer.

But I believe there is only one truth, perhaps hidden behind his seemingly innocent expression.
