Chapter 33

In the early morning of the third day of the crime, Song Wen's team worked overtime as usual in Nancheng police station. Everyone was waiting for the result of an experiment, which would determine the direction of the whole case.

For this result, Song Wen went to Cheng Xiaobing and requisitioned a box of lava chocolate she bought. Xu Yao and other colleagues of the identification center were busy from the afternoon. They even consulted the professor of Chemistry Department of Nancheng University and recruited the precision instruments of Nancheng chemical plant to carry out the experiment.

Lu Siyu sat at his desk, looking at the information. He was so sleepy that his eyes were almost closed. In order to be sober, he got up and went to the bathroom. On the way, he went to the water fountain outside to get a cup of hot water.

What's the feeling of starvation? It's like ice dregs in the stomach, stinging the body, all the organs are crying, all the cells are catching cold, and we can feel the trace of life's passing away. The only word left in my mind is enough to drive people crazy.

Lu Siyu doesn't speak and changes a more comfortable posture. Just when Song Wen thinks he won't tell him, Lu Siyu suddenly looks out of the window and whispers: "Song team, I'm a little hungry..."

"And you?" Song Wen looked at him and said, "what have you experienced?"

Lu Si whispered.

Song Wen couldn't help asking him: "you said that Lin wanwan chose chocolate because it was her favorite candy and the reward she got when she was a child."

Song Wen suddenly thought of their conversation in the afternoon. Everyone's situation and understanding of things are inseparable from his experience and origin. So, what has Lu Siyu experienced, who can see through the criminal's psychology and resonate with the suspect?

Song Wen started the police car. The rain hit the glass of the car and made a faint sound. Lu Siyu's side face was reflected in the front lamp, white, beautiful, cold and indifferent.

"If I put it forward, it's a little too hard on Lao Jia's face. I can't offend all the people..." Lu Siyu said as if he really wanted to stay here, and felt headache and embarrassment for interpersonal relationship.

At first, Song Wen thought that Lu Si's language was not sure. He was afraid that the result of verification was wrong. But later, he found that Lu Si's language had already determined that he was right.

"Well, why don't you let me say that this idea is yours?" Song Wen asked the question in his heart. On the train, after Lu Siyu speculated about the relationship between the dormitories, he thought of testing the concentration of chocolate to determine whether Lin wanwan was the murderer. However, at that time, he made a request that Song Wen promise him not to mention these things to other people.

"It's the evidence of material evidence that solved the case. I just linked the clues." Lu Siyu blinks his eyes and suddenly thinks of Guo's mother's cold hands. In fact, he didn't want to save people. He was just impulsive at that time. Now he's sitting in the car. His body is so tired that he has no peace at the bottom of his heart. He has a little satisfaction. It turns out that justice is just this feeling. This is what song Wen has been pursuing.

Song Wen said: "if the case can't be solved, then Guo's family will be miserable. It's you who saved them."

Lu Siyu said, he didn't think he had done anything great.

Seeing that he didn't move, Song Wen leaned over and helped him pull on his seat belt. Then he praised him and said, "well done, thanks to you today, the suspect was finally killed."

Lu Si language should a, walked over, got on the car, he began to rub his eyes, completely lost the spirit just now. Now he is not only sleepy, but also cold, like in the ice and snow, through the long wilderness, exhausted all his strength, just want to go back to his warm home, holding his dog, have a good sleep.

Song Wen pretended to be new here and waved to him: "you didn't drive today. Come here, the police car will give you a ride."

People continue to walk almost, carrying a bag of Lu Si language this just appeared at the door of the police station.

Song Wen nodded to him.

"Well, just back from the funeral home, another body has just been found." Lin xiuran said and thought of something, "by the way, Guo Guo survived another rescue. Tomorrow, she will be transferred to Hongcheng hospital with better conditions for treatment."

Far away, Lin xiuran got off a taxi and came in with a black umbrella from outside. Song Wen called out: "forensic doctor Lin, work overtime."

At 1:30 in the morning, after working overtime, he finished the final work of the case and prepared for the transfer of the escort. Song Wen drove the police car to the door of the police station, but he was not in a hurry to leave.

The rain in Nancheng finally came down, although it was a few days late. Maybe it's because it's been stuffy for a long time. The rain is very urgent. From night on, big drops of rain form an airtight curtain, which envelops the city. The rain keeps on, and soon accumulates a thick layer of water on the ground. Heaven and earth seem to be washed clean by the rain. The sticky smell in the air disappeared, replaced by the fresh grass fragrance.

If it wasn't for the chocolates, the chocolates she carefully selected, they might not have caught her at all.

Lin wanwan seems to have no sympathy, no empathy, no respect for life, some only her own, others, family or friends, are her puppets, how soft her appearance is, how arrogant her heart is, in her dictionary, panic does not exist, as if everything is not worth it.The human mind is hidden in the body, there are good and bad, some vicious ideas, like vines soaked with poison, grow out of the heart, with the help of human flesh and blood, continue to accumulate, spread, and finally wrap the whole person. There is a malicious person, he may not feel any difference, but others, it is shudder. Once the venom bursts out, it will not only poison others, but also itself.

Zhu Xiao also nodded: "we can not understand such people, does not mean that such people do not exist."

"Do you think Xu Yao's test results will go wrong? Or do you think song's reasoning is wrong? " Fu Linjiang asked him, "she didn't talk about chocolate any more. Instead, she avoided the heavy and accepted the light. She was still winning sympathy. Now, in the face of hard evidence, she is so indifferent, which is not the reaction of normal people. This arrogance and self-confidence itself is her biggest loophole. "

Looking at the interrogation room, Lao Jia frowned slightly and asked, "isn't it really her? Is there something wrong with us? "

Think of the whole process of the case, Fu Linjiang behind the bursts of cool.

All the people in the observation room staring at her, in front of the hard evidence, she still so face, continue to lie.

In the interrogation room, Lin wanwan looked at Song Wen and Lu Siyu in front of her and raised her chin slightly. The interrogation light was shining on her pale face, as if putting her in the spotlight. She soon calmed down, her voice was calm and calm, without any confusion and trembling: "I didn't do those things, I didn't kill my classmates, the medicine was brought by Guo Li, and the chocolate was brought by Guo Li It's what she told them to eat. What you're saying now is just wronging me. " Her righteous words, the eyes, naturally with a pathetic, as if everything really has nothing to do with her.

"Shut up! Don't say any more! " This was the first gaffe of Lin wanwan during the 4:00 trial.

"It's no use trying to deny it now." Song Wen said in a deep voice, "poor your classmates, they should have a better future, but because of you Their lives have been changed. There's always a price to pay for killing. "

Wan Wan Lin looked at him and said coldly, "I didn't do it."

He has interrogated countless prisoners, most of whom are hard spoken in the early stage. At the last stage, they are defeated one by one. They are either pale faced, or crying bitterly, or pulling others into the water. When facing these murderers and suspects, he has no sympathy. It seems that what he is sitting in front of him is just a creature, but not a human being.

"Do you have anything else to say?" Song Wen also looked at her.

When all the truth is revealed, Lu Siyu stops recording and looks up at Lin wanwan. There is not much expression on the girl's face.

At this time, Lin wanwan's confession was not important. The evidence of debris and material evidence was enough to prove that she held down the quilt and suffocated Ma Aijing.

It's all over. They have finally found the key evidence and locked the suspect in this case. Lying in the ward, Guo is just a puppet used by others, and the one who really wants the girls to die is Lin wanwan.

In the end, they used more accurate data to support the experiment.

Once those liquid into the heart of chocolate, fully fusion, each chocolate heart will have a fixed concentration. Those sweet, sticky things, along with her fingers, spread in several corners of the bedroom. Chocolate with bitterness in its sweetness is a lethal weapon, but it also reveals who is the real murderer.

In the bedroom, Lin wanwan suffocated Ma Aijing, and Guo went out to cry for help. The two people's behavior route was completely different. The chocolate with the same concentration was Lin wanwan's trace.

This afternoon, after deducing the whole process, Lu Siyu proposed to ask Song Wen to send the chocolate chips for further examination to test the exact ingredients. There were not many chocolate chips and many of them could not extract fingerprints, but they could help them to locate the murderer.

"The chocolate on the floor of the toilet, the chocolate on Guo Li's mobile phone, and the chocolate on Ma Aijing's quilt are obviously lower than the other three lava chocolates. There is only one possible explanation for this result - "Song Wen looked at Lin wanwan with a sharp eye, like a knife piercing the heart:" the chocolate chips in these places originated from the same piece of lava chocolate. There are your fingerprints on the chocolate left on Guo's mobile phone. We also have your previous testimony to prove that you left this place. So it's not difficult to deduce that this chocolate is what you ate before. The criminal process I just mentioned is the truth of that night. "

Lin wanwan's pupils shrank slightly.

Song Wen said here, his mouth slightly raised: "because this kind of chocolate is handmade, the size will vary, and the injection of green gasification can not be very accurate. We took these chocolate chips for accurate chemical composition identification, so we calculated the concentration of green gasification in the four chocolate balls."

It seemed that she had expected to ask this question for a long time. Song Wen said, "yes, we were baffled by this at first. There was no name on the chocolate. And as you said, lava chocolate is too easy to leave traces. In the packing box, on the paper towel in Dong Fang's garbage can, on the cuff of Ma Aijing's clothes, and on the floor beside Guo's seat, all of them are chocolates. First of all, we distinguish those vomit from fresh and inedible chocolates... "Song Wen's eyes, staring at Lin wanwan's face, in front of the girl heard here, still did not panic. Her tone was indifferent: "those are just chocolate scraps..."

Song Wen turned his pen: "if it's just these discoveries, we can't convict you, because the most important parts are all washed into the toilet by you, but we also find other traces. On the quilt that smothered Ma Ai Jing, we find more traces of chocolate. Those traces are that you grasped the quilt and Ma Ai Jing Kang who was dying He left it behind

"Why do you say that it's me, not Guo Li?" Lin wanwan leaned back in his chair and continued to listen to Song Wen.

Song Wen explained: "but the location of those chocolates is quite special. On the floor of the toilet, we found a drop of chocolate candy. Next to it, we found half of the footprints left on the ground. The pattern and size of the footprints are exactly the same as those of your slippers. Next to the footprints, we found a small amount of glass chips and a small piece of rubber debris. That's why It should be the place where you deal with the injection, the piece of rubber, it should be the glove you cut up. "

Lin wanwan blinked and breathed calmly: "I still remember that when we ate chocolate in the evening, we all got some chocolate on our hands and bodies. Later, they vomited and the dormitory was in a mess. What can this tell us? Maybe my hands got some in the confusion."

Song Wen sighed. The girl in front of her was stubborn and confident. Even now, she was biting so tightly: "what you missed was that some chocolate residue left in your hand, and those chocolates were rubbed everywhere with your hand."

Lin wanwan retorted in a deep voice: "officer, you are really imaginative. I've said many times that it's Guo who suffocates people. "

Song Wen describes these things. If their inference is correct, this is what happened in the dormitory that night. Two girls died because of this. One girl is still in a coma. The murderer, sitting opposite them, listens to all this quietly, as if listening to a story unrelated to her.

"Dong Fang was the first to attack and die quickly. Ma Aijing began to cry for help. At this time, in your hurry, you covered her head with a quilt and pressed her tightly. The poisonous hair and suffocation made Ma Aijing extremely painful. You used all your strength to control her, but it also made you lack skills and couldn't hold Guo Li any more. The frightened Guo Li saw her in the dormitory What happened, ran out from the door of the dormitory You suffocated Ma Aijing. When you heard that the people in the dormitory next door woke up, you also began to have a toxic reaction, so you just dialed 120. "

Speaking of this, Song Wen kept a close eye on Lin wanwan: "unfortunately, as soon as you finished these tasks, before you had time to wash your hands, they began to poison their hair. The bedroom was so dark that you could not do more cleaning work. You went back to your bed, because you were afraid of death, and you hesitated to call an ambulance. At that time, you touched Guo's mobile phone and left chocolate and your fingerprints on it. But you can't guarantee that the ambulance will come after their death, so you hesitated and put down your cell phone

Lin wanwan pursed his lips and didn't speak. Song Wen continued: "you know that qingqiwu is very poisonous. I'm afraid that this chocolate will kill you. So even if you take the one with the smallest dose, you still haven't finished your share of chocolate. You hide the rest of the chocolate in a paper towel. After everyone washes and goes to bed, you sneak in after you turn off the light The toilet flushed tissue, chocolate, gloves and injections into the toilet

"Those chocolates were left standing for a period of time. When you eat them, there is poison in the heart of every chocolate. In the evening, the three of them came back to the dormitory one after another. You are very familiar with each of them and know that they all like to eat sweets. I don't know what kind of rhetoric you used to let Guo Li take the box and share the chocolate. You got the piece prepared in advance, and then the three of them ate it unprepared. "

Song Wen continued: "you must be very curious about where you left your feet. I can restore the process of the crime. For the convenience of poisoning, you choose a kind of net red lava chocolate. There are exactly four in a box. There is a layer of outer skin on the outside of the chocolate, and inside is the sugar core of the chocolate, which is convenient for the dissolution of green gasification. That morning, you pretended to be kind and took back the express when no one was around. In order not to leave fingerprints, you wore gloves and injected poison into four chocolates. In order not to be suspected afterwards, you injected poison into every piece. However, because you are too afraid to die, so you made a mark on one of the pieces you chose. In that chocolate ball, only a small amount of poison was injected

Under the light of the interrogation room, Lin Wan's eyes were as clear as good amber. She looked at the two people in front of her, without arguing or interrupting. The whole person was as cold as a piece of ice.

Song Wen narrowed his eyes and said, "when did your plan start? When you found out that the dog thieves often come to the pet shop? Is it to introduce Guo to his past work? When you started experimenting with doses on stray cats? Or did you deliberately start the war in the dormitory and ask Guo to buy chocolate and Dong Fang and Ma AI to make peace? "Lin wanwan pursed his lips: "officer, what you say, you should pay attention to the evidence."

Song Wen leaned back on her back and looked at her coldly: "you know, forty eight hours is coming. Without any evidence, will I come here to see you?" Then he spoke in a low voice, as if to sentence the girl in front of him: "we have found the key evidence that you want to kill your classmate with Guo's hand."

Wan Wan Lin hugged his arm: "why do you suspect that I killed people? I've said all I have to say. The whole thing has nothing to do with me. "

Song Wen sat opposite her and said, "that means you are not a suspect."

"Is forty eight hours coming? Or did you find out that Guo woke up? According to the regulations, you can only detain me for such a long time. " Wan Wan Lin said, as if he had decided that he was the winner of the game.

As soon as the door of the interrogation room was opened, Lin wanwan moved from lying on her stomach to looking up at Song Wen and Lu Siyu. This was the second day that she was locked in the interrogation room. The first night, she was given special treatment and was locked in a room with a bed for a while. Today, she was locked up here for a day. The long torture made her look very special Haggard, but also particularly poor.

Lu Siyu followed him to get up, the whole person instantly woke up, always cold expression with a little excited.

All the people gathered around when they heard the news. Song Wen took the tables and looked at the numbers on them. He picked them slightly. Then he looked at Lu Si and said, "go, follow me to judge Lin Wan."

Just then, Xu Yao came in from the outside in her high-heeled shoes, and then took out a stack of laboratory materials from her bag: "several chemical laboratories rushed through the night, and finally came out."

Lu Siyu held the thermos cup in his hand and stubbornly shook his head: "well, I guess the result will come out later. I'm also curious about the truth."

Song Wen looked down at Lu Siyu, and the skin that he had just washed was white to almost transparent: "they slept all night yesterday, but they didn't sort out the information. I'm serious. If you can't stand it, you can go to the sofa of the office of the customer service bureau and squint for a while."

Lu Siyu raised his head and said in a low voice, "team song, everyone else is working overtime." He didn't quite understand why Song Wen suddenly felt pity for Yu. If he withdrew alone, no matter what the result was, these comrades who worked overtime would be envious.

Song Wen came over and said, "if you can't hold it, go back."

Lu Siyu was sitting on the chair. He had just finished washing his face with cold water. There were still some drops in his hair. He took out a paper towel and wiped it.

Lao Jia had a premonition that he might be wrong, but as an old criminal policeman, he also wanted to face. He really wanted to apologize to an intern police officer, but he didn't think he could face it. Seeing Lu Siyu coming in, Fu Linjiang never urged him to leave Lao Jia's desk.

Fu Linjiang said: "you follow Guo's line and run back and forth for a day. If you don't find any relevant clues, don't be stubborn."

Lao Jia touched his nose: "it hasn't come out yet."

While he went out, Fu Linjiang pushed Lao Jia: "if it turns out that Lin wanwan is a suspect, you should apologize to Xiao Lu."

Eating is an instinctive demand directly linked with life. In order to eat something, human beings can do anything. So eating is the most important thing in the world, and food is the most important thing in the world. For it, human beings can break out war, for it, they can also ruthlessly deprive other creatures of their lives.

Outside the car, it's raining all the time. It's rustling on the window. The rainy season in Nancheng seems to be coming ahead of time
