When Qiao Zhen reported a string of numbers, Shi Yan began to think about the possibility of practical operation in her heart. As she listened, her expression became more and more relieved, and she fully understood her intentions. She explained to Qiao Raogang, who was still at a loss: "Qiao Zhen listed the numbers to illustrate that in practice, if you combine the thickness of the blade, the blunt knife head such as the serration on the back of the knife can also form a wound on the neck of the deceased if you use a certain force to stab the action. ”

Qiao Zhen made a "you still know me" movement, nodded with a smile, and added: "If you twist and pull out quickly after the piercing action, the damage form is likely to be the same as that of a screwdriver." However, in order to be more rigorous and conclusive, we can do another criminal investigation experiment. ”

"You mean, if the knife in front of you passes the test, it confirms the speculation that it conforms to the relevant professional norms and theories, and can fully correspond to the wounds of the deceased?"

The two nodded at the same time with the relief of seeing a faint glimmer of light in the night.

"Okay, then time waits for no one, let's assume that this conclusion is true, and then continue to scientifically verify it, and see if there is any evidence of the murderer on this knife and the corresponding knife holder."

When Qiao Zhen came out of the laboratory, she almost wanted to play Shi Yan's dance wildly, but in the end, near the forensic office where the corpse was lying, she had to suppress her excitement and want to yell freely, trotting all the way to the interrogation room. Qiao Rao couldn't catch up with her in an instant, and only smiled bitterly when he chased after her: "Be steady, don't miss anything." ”

When he turned around, he met Shi Yan's smiling eyes, and said helplessly: "When will she be as mature as you, I will have one less handful of white hair." ”

Shi Yan waved her hand and smiled: "If you are as sullen as me, Qiao Zhen is not Qiao Zhen." ”

Qiao Zhen felt the wind whistling in her ears, and her feet became lighter and lighter, and all the twists and turns and toil since the corpse shredding case seemed to disappear at this moment. But why is it that the road from the squad building to the interrogation room has become longer than ever?

A few familiar colleagues in the courtyard passed by and looked at her curiously, but she didn't bother to say hello, once again clenched the blue folder in her hand, quickened her pace, and ran to another building at a speed of 100 meters.

When he first entered the interrogation room, the calm and indifferent person was gone, and he watched himself being handcuffed, Li Xiang's body couldn't stop trembling slightly, even if the tremor that could be seen through at a glance was a special joy in a man.

Zhang Chenzhi went to go through the corresponding procedures, and Qiao Zhen sat in front of him and looked at him intently. Before dark, Li Xiang clearly knew that he was destined to lose his freedom.

"Sooner or later, the body will be found, just much sooner than I expected." He began to babble in a low voice, his eyes darkened with fear and regret.

Qiao Zhen had heard that the criminal police were often forced to face the murderer's long confession before being taken into custody, even if they were not asked to do so at all, but the long-term concealment and suppression at this moment were like a floodgate that had been washed away, making it difficult for people to control themselves. But really facing this scene, it still makes her a little uncomfortable to snoop on other people's privacy. She sat down slightly, listening to him.

"I'm really tired of it, I'm tired of it, I can't tell when I started to get tired of it."

"Tired of what?" Qiao Zhen asked, instead of letting the trolleybus of the criminal in front of him drive indiscriminately, it is better to explore the true thoughts of the murderer, which can also be used as a case accumulation for criminal psychology research. Compared with the detailed analysis of past cases in class, she believes that the cases she has experienced can deepen her memory and understanding.

Li Xiang didn't seem to hear her question, and said to himself: "The day before, I told her that my fiancée would come over soon, and we used to say that as long as my fiancée came over, she would stay in a hotel outside for two days. But this time, she was very resolute and refused to agree. ”

"You're doing this because you're afraid your fiancée will know about your relationship?"

"When I was a child, my family was very poor, and as you can see, my life is very difficult now. Why do others eat and drink spicy food, I can only calculate the rent and watch the boss's face live? ”

"What does your fiancée like about you?" Qiao Zhen asked, glancing inquiringly at the monitoring probe, and seemed to be able to feel his father watching in front of the monitoring screen. In fact, this grim attitude seems to be for her alone—expressionless, as always, neither encouraging nor opposing, as if waiting for her to fail, to withdraw, to fear, and to give up. She hated having such a partner in the workplace, let alone her father, who needed support the most.

"She? She was a rich girl and never lacked anything she wanted. She is surrounded by rich second generations who are generous. Compared with them, a year's salary is not enough to cover their pocket money for a day. What do you say she likes about me? I don't know? ”

Qiao Zhen listened quietly without any judgmental expression on his face. In this way, he will speak his heart unguardedly.

"I only know that if I am with her, the rest of my life will be different, not to mention how prosperous it is, but at least I can buy things without looking at the price, and I am not afraid to take leave when I go out to travel, because I don't need to ask for leave at all. Now, you're asking me to give up this fiancée and live with a woman as poor as I do? It's a normal person, who would want to? ”

"Everything is not so absolute, there are still many couples who start from scratch and share weal and woe."

"But that's someone else, do you know how much I paid for her?" Li Xiang opened his rootless fingers, his eyes glared viciously, "After five years of waiting, and five years of savings, I didn't want to spend any of it, all of it was spent on my fiancée." ”

"Isn't she short of money?"

Li Xiang didn't answer for a while, and was silent for a while and said: "Sincerity is the most worthless, my sincerity is to give everything, even if it's only so little." ”

"You put the corpse under the bed, can you sleep?"

"Of course I was scared, my fiancée wanted to do something with me, and I felt a chill down my spine. Those eyes were staring at me from the moment she took her last breath. I wanted to run away, but I didn't dare to leave the bed. ”

"Afraid your fiancée will find out?"

Li Xiang's voice trembled: "The smell was very subtle at first, and I could only detect it if I smelled it carefully, and in those days, I kept asking myself, 'What should I do if I am so big?'" Later, the smell became more and more obvious, and I also came up with the idea of breaking her down, so I hurried up and told my fiancée that I was going to work overtime and break her up. ”

"She doesn't suspect it at all?"

"I said it was a problem with the sewer in the rental house, and she believed it."

"She trusts you, doesn't she?"

Li Xiang shed a few tears and nodded deeply. It's not remorse, it's not nostalgia, what Qiao Zhen sees is a person who has lost his future rich life, a face of hatred, and undisguised unwillingness.

"I know I'm done. But instead of dying, I wanted to continue to live. I didn't have the heart to kill her, if it weren't for the fact that she pestered me, grabbed my keys, didn't let me go to work, and wanted to call my fiancée, there would be no follow-up...... In the end, it was her stubbornness and domineering that killed her. ”

"What did you think when you cut off her head?"

Li Xiang was furious: "What can you think? I just think of it as a dead cow, and I used to work like this in a Chaoshan hot pot restaurant. ”

When faced with unbearable fear, people's reactions are either weeping bitterly and tears, some are silent and autistic, and some, like Li Xiang, are suddenly angry and embarrassed.

Qiao Zhen ignored his roar, just like facing the flickering of a broken candle in the wind, a glance, and she didn't mind being more ferocious than him when dealing with the cruel murderer: "You killed your child's mother with your own hands." ”

"Really? My baby...... He is so small, he is not a person, I took him into this world with my own hands. ”

"No, you sent him out of this world with your own hands. He doesn't even have a chance to see the world, just because you want your so-called happiness. Qiao Zhen said to him coldly, the gold necklace around his neck was like another shackle at the moment, pressing his head down heavily.

"I sent him away with my own hands...... Who will send me away? Li Xiang's eyes were a little distracted, and he muttered as he asked.

Zhang Chenzhi pushed the door in, and he saw a rare expression on Qiao Zhen's face—he was stunned for a moment—it was a cruel expression that put the enemy to death.

He glanced at the dejected Li Xiang on the other side, and understood seven or eight points in his heart, thinking about it, it would be a good choice to use her to break the suspect's psychological defense next time. Unexpectedly, Qiao Zhen and Shan's body hid such an explosion of energy, so that he wondered if she was in the dark, and her dark side was usually not revealed.

Or is there such a dark side to everyone that they don't know about?
