"This ...... That's because the murderer was so fast, I mean, cut your throat, you must have died all of a sudden, and you didn't have time to scream. Chen Song said in a bit of a panic.

"I'm not talking about the victims. I'm talking about his daughter, the six-year-old girl. Yang Wenbin said calmly.

"What?" Chen Song didn't react for a while.

"You haven't forgotten, have you? Strictly speaking, the first discoverer of Ke Yan's body was not your guard, but his youngest daughter Ke Yueqiu. Anyone who sees their biological father lying in a pool of blood will subconsciously scream loudly, let alone a six-year-old girl, poor child. Yang Wenbin sighed and continued, "And you just said that you and the guards are playing cards in your office. As far as I know, your office and the guardhouse are very close to each other, and they are diagonally opposite Xiao Yang's cell. If the truth is as you say, you should hear the little girl screaming in addition to the alarm bell, then how did you end up in the cell on the other side? ”

"This ...... I ......" The cold sweat on Chen Song's head slid down suddenly.

"You're right, the night Ke Yan was killed was two or three o'clock in the morning, which is a time when it is easy for the guards on duty to get sleepy and nap." Yang Wenbin said slowly, "If my guess is correct, your so-called 'playing cards with the guards' is probably the guards falling asleep while playing cards." You can use this opportunity to sneak out of the office and kill Ke Yan. It didn't take long for the napping guard to hear Xiaoqiu's scream, so he woke up and rushed to the scene of the crime, right? ”

Although Chen Song was already quite flustered, he still held on to the bottom line: "You can't say that...... You, you have no proof! What about the evidence? ”

"Oh, really?" Yang Wenbin curled the corners of his lips and showed a smile that seemed to have no meaning, "Do I really have no evidence?" ”

Yang Wenbin's fingers were still tapping on the table, neither hurrying, nor slowing. It's just a gentle tapping, making a rhythmic sound.

Chen Song's gaze began to drift, drifting to Yang Wenbin's fingers tapping on the table from time to time.

"First of all, as a civil servant, you don't embezzle half a little bit of public money." Yang Wenbin suddenly said, "Yan Junli and I investigated those documents, and found that you have embezzled a large amount of public funds and revised accounts in the name of public welfare construction in the past five years. The amount of money you embezzled adds up to enough to put you in jail. You don't want this kind of thing to be exposed, do you? But what, things don't always go as planned, it's Ke Yan who discovered your ugly crime, right? ”

"Y-How do you know!" Chen Song raised his head abruptly and blurted out in horror.

Yang Wenbin smiled and did not answer, but continued, "You made a choice between going to jail and risking murder, and you chose to kill. And to be honest, you're a little clever because you figured out to have a murderous prisoner take the blame for you. On a dark and windy night, you slept while the guard playing cards with you was asleep, sneaked up in front of Xiao Yang's cell and released him. Then, you killed Ke Yan with the strychnine you bought from the prisoner and a sharp knife, and then dragged Ke Yan into Xiao Yang's cell, pretending to be the revenge of the murderer of the serial throat cutting case five years ago. The excuse was so successful that no one doubted the truth at first. It's not surprising that humans are accustomed to labeling other people, thinking that murderers are sure to kill again. ”

"But in this world, as long as it is a lie, it will inevitably reveal flaws. From the very beginning when I came to the prison to inspect the scene, I found that there was no sign of the cell door being broken, and there were no signs of fighting around the door. From then on, I began to suspect that Xiao Yang did not escape from prison by himself, but someone deliberately released him. Then, we just found this in your office files. Yang Wenbin stretched out his hand and held a form in his hand, "This is the release document of your execution agency for death row prisoners, just the day before Xiao Yang escaped from prison, you went to the place where the death row prisoner was executed, for what?" It should be so that Xiao Yang, who escaped, could be transported out together in the corpses of the dead. In such a well-run municipal prison, this is the only way to escape. ”

"Let's talk about your strychnine." Yang Wenbin said and stretched out his hand to Yan Junli behind him, who knowingly handed over a plastic vial, which contained some black seeds, "You said that this bottle of strychnine is your traditional Chinese medicine?" ”

"That's right." Chen Song said with a stiff neck.

"That's fun." Yang Wenbin raised his hand and showed the bottom of the bottle to Chen Song, "Then you have to help me explain what the letter 'j' at the bottom means." ”

"What? This ......" Chen Song was stunned for a moment, and at a fixed glance, there was really a vague "J" on the bottom of the plastic bottle.

"Don't know? Let me explain it to you. Yang Wenbin put the medicine bottle on the table, "j is the initial letter of the English word ''', which is 'clown'. I really don't blame you for this, but the original owner of this vial is really a neurotic with an extreme desire for control, and he will definitely leave his mark on his possessions. ”

"But, but this could be something else—" Chen Song still wanted to struggle, but was gently interrupted by Yang Wenbin.

"Relax, we still have a lot of money to settle." Yang Wenbin showed a smile, "Let's talk about Xiao Yang's death again." Do you know? I've always felt like I've seen a lot of ruthless criminals, and some of them are really despicable, but I've never seen anyone as despicable as you are. Really, it's the first time I've seen it. You know that Xiao Yang is a filial son, and you also know that the police assessed Xiao Yang as having a serious mother-love complex at that time, so you know that Xiao Yang can give everything for his mother. So you use his mother to provoke him, and you know that he can take the bait with just a little provocation. You ostensibly helped Xiao Yang escape from prison, but in fact you just need his escape to cover up your dark and disgusting crimes. From the beginning, you didn't intend to keep him alive, and from the beginning you calculated that as long as he lived, you would be in danger. yes, you don't even have to think hard to kill him, you just have to force his mother's life to force him, and he'll obediently hit you at the muzzle, isn't it? ”

Chen Song was so frightened by Yang Wenbin's momentum that he shuddered violently, and subconsciously retreated.

"However, it was Xiao Yang's death that finally sent you here." Yang Wenbin's tone became soothing again, and he said slowly, "The cut letter sent to the police station was indeed written by Xiao Yang at the beginning. But instead of cutting and pasting, he wrote it directly on the paper, which is the line: 'I was born in hell and now return to the arms of death.' The letter was not a threatening letter, but a suicide note. But I don't know why, this letter must have been stopped by you halfway. You suddenly had a plan, cut out the printed words from newspapers and magazines, pasted them on Xiao Yang's original handwriting, and made a threatening letter to the police. Arrogance, ignorance. ”

Yang Wenbin shook his head and said, "It was this arrogance and ignorance that made you not directly destroy the letter, so that we followed these clues to find you." You don't want us to find Xiao Yang's body before you do, so you want to cover up the letter, but unfortunately we not only found the letter, but also found the body one step ahead of you. Xiao Yang's body gives us two clues. One, it's your name that he wrote on the sewer wall, but due to the washing of sewage, there is only one radical left. Two, it's this bullet. ”

Yang Wenbin took a transparent evidence bag from Yan Junli's hand, and a small bullet was lying inside.

"The bullet is a 7.65mm caliber bullet, and it should be paired with a small semi-automatic pistol." Yang Wenbin shook the bag and said, "The standard weapons of the criminal police and prison guards in City C are small semi-automatic pistols that are easy to carry, but the guns that criminals buy on the black market are often more lethal, and they generally do not choose such guns." ”

- For example, the poppy's gun is Colt. Yang Wenbin muttered in his heart. In a way, she is one of the "criminals".

"I think I have enough good reason to think that this is Xiao Yang's last fight before he died, that is, to let the police know that the real murderer is you." Yang Wenbin calmly came to a conclusion.

Chen Song's palms were already wet with sweat, and he raised his head but didn't know where to look. Just when Yang Wenbin thought he was going to succeed, Chen Song suddenly said something coldly.

Dr. Yang ...... I've always admired you, and your reasoning is really wonderful. Chen Song glared at Yang Wenbin, clenched his hands into fists, and gritted his teeth and said, "But I found that what you said from just now to now has no practical value, right?" Because you don't have any real proof at all! ”

Yang Wenbin lowered his eyelids, adjusted his sitting posture, and his fingers, which had been tapping on the table since just now, suddenly stopped. No one spoke in the room, and for a moment there was a deathly silence in the air.

Yang Wenbin was just silent, didn't say a word, and looked at Chen Song quietly. And the latter gritted his teeth, as if he didn't want to admit defeat, and glared back in a daze.

The atmosphere was so uncomfortable that even the well-trained Yan Junli was standing behind him, and he began to feel uncomfortable.

Suddenly, the silence was broken. It is Yang Wenbin's index finger.
