The reason why Shi Feng and Wang Zi's mother went to wake him up was to observe his first reaction when he saw him.
When Wang Zi heard that the police were coming, his legs trembled subconsciously. Putting aside this point, it might just be a convulsion.
After seeing a stranger, he immediately chose to look away. This was one of the manifestations of low self-esteem. Coupled with his mother's statement, Shi Feng initially judged that Wang Zi was an introvert and an impulsive criminal.
Pupils will shrink when a person is depressed and has a negative attitude.
When going down the stairs, Shi Feng deliberately walked in front and exposed his gun just to observe Wang Zi's eyes. Generally, teenagers will show interest when they see a gun when they haven't committed any crime. Only criminals will be panicked by the police's guns, because They know that the gun may be pointed at them, and they will subconsciously feel fear.
At this time, Wang Zi, who was sitting in the car, lowered his head and tried his best not to look around and avoid revealing his fault. After all, students are just students. Not everyone is as calm and calm as Ai Liang and knows how to control facial expressions.
Although Wang Zi thought his face was expressionless now, in fact, his inner panic had long been captured by Shi Feng's eyes. His brows were raised, there were shallow wrinkles on his forehead, his lips were slightly pursed and stretched back, and the muscles in his mandible were trembling. , tight leg muscles, white fingertips, etc. These are all signs of fear, and they can be said to be full of flaws.
According to Shi Feng's viewing of the chat records between him and Gao Jiajia yesterday, Wang Zi is not so introverted that he would become fearful when meeting strangers. Otherwise, he would not have taken the initiative to drive away the scavengers harassing Gao Jiajia. Now that he is so scared, it is obviously There is something wrong in my heart.
While Shi Feng and others were escorting Wang Zi, Xia Qinian also came to Shi Feng's office.
"Brother Nian, you'd better hurry up. Captain Shi may be back soon." Wang Xun stood at the door of Shi Feng's office with a folder, pretending to have something to report and waiting for Shi Feng to return.
Xia Qinian whispered: "I know, don't rush me."
The layout of the office is very simple, with a desk, a couch, two chairs, a bookshelf and a filing cabinet, but nothing else, not even a water dispenser.
After all, Xia Qinian's uncle was the former captain of the criminal police team. He often ran here when he was a child. He still remembers the arrangement of documents. He quickly found the file from ten years ago, but the content inside was unexpected.
Wang Xun, who was waiting outside the door, saw Shi Feng's car coming back. He was just about to knock on the door to remind him when he saw Xia Qinian coming out of the office with a gloomy face and returning to the interrogation room without saying a word.
Wang Xun didn't have time to care about those details and hurried up to the second floor to return to the technical department. If Shi Feng saw him guarding the door of the office, he would definitely guess what he was doing.
In the interrogation room.
Wang Zi was taken to the interrogation room and sat down, his hands cuffed to the chair. This posture did not look like he was asking about Gao Jiajia. He was clearly being interrogated as a prisoner.
Shi Feng and Gao Bin came to sit opposite him with an evidence box and a notebook and a voice recorder. Every move they made and every sound they made stimulated Wang Zi's sensitive nerves.
Shi Feng didn't speak, and Gao Bin spoke on his behalf: "Do you know why you were brought to the criminal police team?"
Wang Zi remained silent.
Seeing that he remained silent, Gao Bin asked the next question: "What do you want to say about Gao Jiajia's death?"
Wang Zi remained silent.
This situation had been rehearsed in his mind countless times. His silence was not because he didn't want to speak, but because he was too nervous to speak due to fear.
In fact, it doesn't matter how many times you practice it in your brain. The imagination and reality are completely different. Just like meeting a tiger in your imagination and using a sliding shovel, if you really meet a tiger in reality, you will definitely be so scared that you dare not move, and your legs will be so weak that you can't walk.
The black tone of the interrogation room, the sharp eyes and stern tone of the detective across from him, and the expression of 'please admit it quickly', all these are tugging at Wang Zi's heartstrings. His heartbeat is getting faster and faster, and his throat is filled with tears. They were all trembling with the violent heartbeat.
Wang Zi struggled to say a word: "I... don't... know..."
All the pre-rehearsed and prepared answers disappeared. His brain was completely blank at this moment, as if it had turned into mush and he could not concentrate at all. No matter how hard he tried to recall, he could not recall the answers he had prepared before.
In the past, I watched criminal suspects on TV hesitating and not knowing what to say as soon as they arrived in the interrogation room. Wang Zi even laughed at them. Only when it was his turn could he understand how much psychological pressure they were under. Those who faced interrogation and lie detection A person with a calm face and a heart that doesn't beat is either a psychopath or a genius.
Gao Bin doesn't care. There are many people who answer "I don't know" here, and he has long been used to hearing it. To deal with such people, as long as their psychological defenses are broken, they will talk about anything.
But this kind of work is usually not done by him.
Shi Feng put down his pen and pushed the notebook in front of him. Although Gao Bin still had a serious look on his face, he was wailing in his heart.
"After school on Thursday, where were you during the hour from nine to ten? The surveillance in the community showed that you returned home after ten." Shi Feng crossed his hands and stared into Wang Zi's eyes.
Wang Zi's planned answer was that he was going to have a late-night snack: "I'm going to eat..."
As soon as the words left his mouth, Shi Feng interrupted directly: "You were not seen in the surveillance cameras near the school or the snack bar, and the nearby snack carts will close their stalls around 9:30. Which snack shop are you at? A late-night snack bought in the car? Are there any classmates you know nearby who can testify for you?"
Shi Feng's action of interrupting Wang Zi was interrupting his train of thought and not giving him time to formulate his reasons. Many criminal suspects will prepare their confessions before being interrogated. What their interrogators have to do is to ask some unexpected questions to disrupt their plans. The answers given in a hurry will inevitably reveal flaws.
"I..." Wang Zi didn't know whether the police checked the surveillance or not, and for a moment he didn't know what to say.
"Next question, is the red string in your hand a gift from Gao Jiajia?"
Unlike the previous questions that required judging the organizational language, this question only requires a yes or no answer.
"Yes." Wang Zi answered quickly this time. He had not stated clearly the previous questions. The two people's suspicion of him must have been growing, and he was trying to restore some credibility.
After answering, Gao Bin's eyes changed when he looked at Wang Zi, as if he had been sentenced to death.
Because his answer means that Shi Feng has completely grasped Wang Zi's psychological activities.
Sure enough, children are still too young mentally. How can you fight with Captain Shi if you are so stupid?
Gao Bin shook his head and continued writing furiously.
"What were you doing between twelve o'clock last night and early this morning?" Shi Feng gave a fatal blow.
Gao Jiajia had just died a day ago and Wang Zi thought it was impossible for the police to directly identify him as the murderer, let alone stare at him in the middle of the night. According to Wang Zi's guess, it would take two or three days before the police suspected him and sent people to monitor him. It would be no problem to dispose of the crime tools during this period.
His mind went blank again.
Did you identify the murderer as me from the beginning and monitor me? This is impossible!
The glasses are suspected! His suspicion is obviously greater than mine! Why! Why would they know I was out in the early hours of the morning! It's only been a few hours since I threw my gloves away, and it's too late even to adjust the monitoring! And I didn’t go through the main entrance at all! They must be scamming me!
"I'm sleeping..." Wang Zi replied in a low voice. He tried his best to suppress his breathing to prevent himself from showing nervousness. His spirit had been oppressed to the extreme and his mind was in chaos.
Shi Feng saw that the time had come, and he took out the evidence directly from the evidence box: "The forensic doctor who conducted the autopsy extracted two types of fibers from Gao Jiajia's nails. One is white fiber and the other is red fiber. Please give your hand Take off the red string on it, we need to compare it."
Wang Zi stared at the slightly invisible red fluff in the evidence bag and was completely stunned.
"Also, we found a pair of white cotton gauze gloves packed in a black garbage bag in a waste recycling station this morning. The scratches on the gloves matched Gao Jiajia's fingernails, and fingerprints were found on the garbage bag. Please check this There are fingerprints left on the test paper and we need to compare them.”
Now this sentence is deceiving Wang Zi. He just got the garbage bag from Ai Liang this morning. He didn't have time to compare the scratches, but fear has completely dominated his brain. Two sentences: 'We need to do something. Contrast completely defeated Wang Zi's psychological defense.
Now that the police have the evidence, what's the point of him continuing to resist?
Wang Zi suddenly burst into grief and cried bitterly: "I killed the person...Jiajia is sorry...I'm sorry wuwuwuwu..."
Looking at Wang Zigaobin who was lying on the table crying and crying, not only did he not have any sympathy, he even felt like laughing.
Why didn't you think about it when you committed the murder?
Now that they all admitted that he killed the man himself, Wang Zi had no intention of continuing to conceal the motive and process of the crime.
From hearing that Gao Jiajia was about to confess to others that she had murderous intentions due to anger, to how to cut off the surveillance power, how to blame the school's scavenger glasses, and how to clean up traces of the scene and sort out the clothes of the deceased, all the details were explained clearly. Bin looked shocked.
It can be said that if Wang Zi hadn't been timid and skipped cleaning the deceased's nails, destroying gloves and clothing, etc. and was hoping that the police would not notice these details, the police would have been unable to do anything to him even if he openly admitted that he was the murderer. .
"Who taught you these?"
Shi Feng's eyes suddenly became sharp. Based on Wang Zi's performance just now, Shi Feng could conclude that this was definitely not a method he could come up with. There must be a mastermind behind it, and this mastermind was very dangerous.
"I read it in a novel." Wang Zi lowered his head. This was the most relaxing moment for him in two days. After admitting his crime and crying loudly, his heart also calmed down.
Shi Feng continued to ask: "What is the name of the novel, and what is the author's pen name? What is it roughly about?"
Wang Zi told the story in general, and said that this novel should be the original manuscript with only the title of the work.
"I just read the story in it, so..."
Wang Zi also regretted picking up that novel at this time. If it weren't for the strange attraction of the words and the protagonist's complete relevance to his life, things would not be what they are now.
Shi Feng's heart is not much better than Wang Zi's. If it is true as he said, then the author of the novel must have been secretly observing Wang Zi's life and persuading him to embark on the path of murder. This kind of person is obviously an antisocial personality and extremely dangerous. .
"The name of the novel?"
"Narcissus."
"When did you pick up this novel?"
"Two years ago in the first year of junior high school." Wang Zi answered honestly.
"What?"
Now it was Shi Feng's turn to be shocked. Does that mean this is just a coincidence?
Wang Zi is just imitating the story in the novel? After all, no matter how powerful the author is, it is impossible to predict the future.
"What about the original manuscript of the novel? Did you throw it away?" Gao Bin took advantage of Shi Feng's silence to ask on his behalf.
"It burned yesterday."
There are criminal methods above, and Wang Zi will certainly not stay.
"Burned? Why didn't you know that your gloves were burned and you had to throw them into the recycling bin?" Gao Bin obviously didn't believe Wang Zi's nonsense.
"The water in the house was cut off during the fire, and the toilet couldn't be flushed..."
Gao Bin covered his face with his hands and was completely speechless. If the water supply had not been cut off yesterday, the key evidence that they were a day late would have been lost. Is this guy unlucky or are they lucky?
This is the first time Shi Feng has encountered such a fool in all his years of working on a case. He even copied the perfect crime script and couldn't copy it.
After the two finished the work, they took Wang Zi and locked him up, and notified his parents and the victim's family of his confession.
