Wu Zhizhi turned on Liu Yong's computer, went straight to the shopping page, clicked on the purchase record, and it was not disappointing.

The three volumes of the Forensic Record, as well as sodium cyanide, were all recently purchased.

Wu Zhizhi took out his mobile phone and took a photo.

Just as he was about to turn off the computer, a voice came from outside: "Dayong, you are back, you came just in time, there is a police comrade in the house, waiting for you in the house." ”

In the blink of an eye, the door opened, and Liu Yong stood at the door, his face a little serious.

The old lady still didn't know what was going on, and said enthusiastically: "Oh, this computer was repaired so quickly, the police are the police, it's just not ordinary!" ”

Wu Zhizhi smiled and said, "Of course, grandma, I have long said that you don't have to worry," and then looked at Liu Yong, "Hello Mr. Liu, I am Wu Zhizhi of the Xinyang Criminal Police Brigade, this is my certificate, there are some things I want to know from you, I hope you won't mind." ”

"Don't mind, don't mind!" The old lady answered for Liu Yong, and came in with tea from outside the door, "You talk about business, I'll cook!" ”

The door closed, Wu Zhizhi looked at Liu Yong, smiled and pointed to the bed and said, "Please sit down Mr. Liu, this is your home, don't be polite to me." ”

Liu Yong's expression was a little solemn, and his eyes were fixed on the "Forensic Record" on the table and the shopping page that was opening on the computer.

"Mr. Liu, I think you should know what I'm here for."

A hint of panic crossed Liu Yong's face.

Wu Zhizhi put the "Forensic Record" and the computer in front of him: "Mr. Liu, please explain." ”

"I ...... I'm ......."

Wu Zhizhi looked at him, but he didn't say a word for a long time.

"Okay, if you don't say it, then I'll say it for you." Wu Zhizhi's gaze turned cold, "You helped Sun Chen secretly take photos of Jessica and Andy's private meeting, Jessica already knows about this, you know Jessica's style of doing things, and you also know that she hates being betrayed the most, so you know that you are going to be unlucky, but you are just her driver, even if you quit your job, as long as you stay in Xinyang, she has a way to make your life worse than death, so you have to do this." ”

Wu Zhizhi pushed the "Forensic Record": "You don't know what method to use to make her disappear unconsciously, so you have to turn to books, page 59 of this book, which records a good method, and what is even more rare is that you can also understand it." On the day of the crime, at 18:35, you took the opportunity to deliver the key to Jessica, sneaked into Jessica's office, poisoned her, where did you go, do you still need me to say? Everything that can be imported in Jessica's office, we have taken it back and tested it, coffee, cake ......"

Liu Yong stood up violently and glared at Wu Zhizhi.

Wu Zhizhi also looked at him, smiled and said: "Your old mother, who is over seventy years old, is very proud because of such a down-to-earth son as you, and now her only wish is to see you give birth to a big fat grandson in her lifetime." ”

Liu Yong sighed deeply again and sat down.

"As long as you admit your guilt and have a good attitude, there is still a chance to reduce the sentence." Wu Zhizhi said as he learned from He Sibai.

Liu Yong was silent for a long time and finally nodded: "Okay, I plead guilty, and I will surrender with you." ”

An hour later, Cheng Dahei took Liu Yong back to the police station, and glared at Wu Zhizhi with a dark face: "What are you doing here!" ”

"Captain, it's not me who is a moth, it's the suspect who wants to turn himself in."

"Turn yourself in! What a surrender! Lian Yin Tian was furious and slapped the table hard, "I asked you to investigate the fraud, what are you doing!" ”

Wu Zhizhi looked at Lian Yuntian a little confused: "Captain, are you old and confused?" Now that Beauty's case is not closed at all, you just let me investigate some inexplicable bullshit scam! What is a scam? What is murder? Which is important, can't you tell which one is important? ”

"You!" Even Yin Tian pointed at Wu Zhizhi's nose, his hands were trembling, "Don't think that I signed that bullshit promise letter for you, you can do whatever you want!" I write in black and white that I will not use 'all kinds of illegal and other improper means' to force you to leave the Xinyang Investigation Brigade, which does not mean that I cannot fire you for reasonable reasons! As a police officer, you do not carry out the tasks assigned by your superiors, you are self-righteous and maverick! I still have a reason to fire you! ”

"Open! Then you open it and try it! You caught the wrong murderer yourself and created an unjust, false and wrongful case, this is the reasonable reason for you to fire me! ”

"Unjust, false and wrongly decided cases......" Lian Yin Tian gritted his teeth, "Okay, I'll discuss it with you, I'll discuss it with you, whether it's an unjust, false and wrongly decided case!" Wu Zhizhi, let me ask you, among the foods found by Li Jiexi's company, which ones she has eaten and which ones she has not eaten? ”

Wu Zhizhi sat back on the bench with his chin held high: "Coffee, birthday cake, she has eaten, she has never eaten black truffles." ”

"Then let me ask you again, what lethal drugs are contained in these foods?"

"Coffee is cyanogenic glycosides, birthday cakes are cyanogenic glycosides and potassium cyanide, and black truffles are potassium cyanide and sodium cyanide."

"What kind of medicine did Liu Yong use?"

"Sodium cyanide."

"Has Jeremy Lee eaten?" Even on a cloudy day, he slapped the table.

Wu Zhizhi paused, raised his head and said, "No." ”

"Nope! You know no! She hadn't even eaten it! She hadn't even touched it! That Liu Yong turned himself in, I want to ask you, what kind of head he is! ”

Wu Zhizhi looked at the angry Lian Yintian and suddenly smiled: "Lian Yintian, I said that you are an old fool, and you still don't admit it." ”

"What else do you have to discern? Yes? How else do you want to tell! ”

"I can't stand it," Wu Zhizhi stood up and took a pen from in front of him and pulled out the notebook from under him, "I can't stand it, come, I'll give you a good analysis." ”

Wu Zhizhi is in a notebook, writing and drawing.

"First of all, the suspect is locked between Su Feiyan, Liu Yong, Andy, Sun Chen and Lin Zhongshi, Su Feiyan is preparing coffee, Andy is preparing black truffles, Sun Chen is preparing birthday cakes, and Lin Zhongshi's almond syrup, is there a problem, captain?" Wu Zhizhi raised his eyes and looked at Lian Yintian's face.

"You say!" Even cloudy days have impatience written on his face.

"Almond juice is not poisonous, and considering that the poisoning time of cyanide poisoning should be less than an hour, Lin Zhongshi is excluded, and according to my interview with Lin Zhongshi, he obviously has no feelings for Jessica, whether it is emotional or profit, he has no motive to kill."

Wu Zhizhi looked at Lian Yuntian and continued: "And the black truffle prepared by Andy was sent in at ten o'clock in the morning, and Jessica didn't move until half past six in the afternoon when Liu Yong went to black to poison the truffle, according to Liu Yong's description, he originally planned to apply sodium cyanide to Jessica's cup, but because he saw Andy's cake, he temporarily changed his mind, but anyway, Liu Yong's sodium cyanide and Andy's potassium cyanide, Jessica didn't take it. ”

"So, the last thing to kill is Su Feiyan's coffee!" Even on a cloudy day, he slapped the table impatiently.

"It's not." Wu Zhizhi replied decisively, "Because Su Feiyan said that she walked into Jessica's room twice with coffee, the first time she didn't have a chance to poison because there were colleagues around her, and the second time she poisoned Jessica was after half past eight." ”

"So! The time of cyanide poisoning is less than an hour, which is consistent with the circumstances of her confession, if that Jessica had drunk poisoned coffee before half past eight, then the time of her poisoning would have been an hour earlier, and she would have died at the birthday party! And this detail is only known to the poisoner Su Feiyan! ”

"But the problem is that when Su Feiyan brought out the coffee for the second time, there was only half a cup of coffee in the coffee cup, which can be proved by the camera at the door of Jessica's office, I saw with my own eyes that when Su Feiyan came out at 8:35, she only had half a cup of coffee in her hand!"

"So what?"

"But there's only one lipstick print on the coffee cup!" Wu Zhizhi patted the table and said, "There is only one, which is completely printed on the side of the cup." ”

Lian Yuntian was suddenly stunned, and after a while, his face shook a little: "That is, she has only drunk it once." ”

"Yes, she only drank it once, but that time was before Su Feiyan was poisoned."

Even the cloudy sky was silent for a while, he had completely calmed down, frowned and said: "That can't be Liu Yong, sodium cyanide only appears in black truffles, only on that." He tilted his head and thought for a while, "Is it possible that Sun Chen, I have read the record of your conversation with him, and his words ......" Even Yin Tian shook his head again, "There are still loopholes." ”

"I also thought so, so I told him a lie at the time to deceive him, I told him that the poison on the cake was very likely to be done by outsiders, not necessarily against Jessica, and then I asked Wei Song to follow him, but I didn't expect him to believe it, and even went to the hospital to wash his stomach, I think if he was poisoned, then he has no reason to do it, even if he is cautious and really finds Wei Song and him, he should not make such an exaggerated move as gastric lavage."

"But this is still not evidence......"

"I know, in fact, I don't have any evidence, but I'm still thinking, whether it's Sun Chen, or Lin Zhongshi, I think for them, with their identity, they have more and more legitimate ways to realize their own interests and achieve the goals they want to achieve, killing people, if it weren't for the point that it had to be so, they shouldn't do it, after all, the price of killing is too great, they are all careful people, and they won't be so indistinguishable."

"Theoretically it is tenable, but there must be evidence, it's just hypothetical, this can't work."

"If this is a hypothesis, then I have an even more powerful hypothesis." Wu Zhizhi said.

"What hypothesis?"

Wu Zhizhi blinked: "There is no evidence." ”

"Tell me about it first." Lian Yuntian frowned and looked serious.

"Andy."

"No!" Even the cloudy day waved his hand, "Impossible, Li Jiexi didn't eat the cake he sent." ”

"It's not a black truffle, it's a birthday cake." Wu Zhizhi said, "I have learned that the cake that Jessica ate passed through the hands of Sun Chen, Andy, Liu Yong, and Su Feiyan, but Sun Chen's contact with the cake was with Jessica, they just held the knife together and took pictures with the cake, and then there was no chance to touch the cake, and then it was Liu Yong who cut the cake, Andy was responsible for the distribution of the cake, and he should have given the cake directly to Jessica, but because his relationship with Jessica was more sensitive recently, he changed hands to Su Feiyan. ”

"If that's the case, then this case is still very complicated, and now even if Sun Chen is excluded, there are still three people to be suspicious."

"But Liu Yong only has sodium cyanide in his hand, and the cake is cyanogenic glycoside and potassium cyanide, just like potassium cyanide Andy has it, and cyanogenic glycoside Su Feiyan has, Su Feiyan said that she came out of Jessica's office at half past eight to add almond flour to the cake, of course, she may still be poisoned in this matter, but I think that since she has already turned herself in, it seems that it is not necessary to lie like this at this time."

"So you're still suspicious of Andy?"

Wu Zhizhi nodded: "I suspect that he has two reasons, the first is that he has a chance, and there is indeed potassium cyanide on the cake, when there is no other evidence that others also have potassium cyanide in their hands, I think only he is possible." The second is that he still didn't tell the truth when he took the transcript, and he told us that he wanted to kill Jessica just on the spur of the moment, but he wasn't. As far as I know, Jessica is a woman who can't be provoked, if he doesn't get rid of Jessica, then in the future he will have a life that is worse than death, so just like Liu Yong, they all know Jessica's personality very well, which is why two people who betrayed Jessica would poison her together. The biggest difference between the two of them is that Liu Yong doesn't know if Jessica ate the black truffle in the end, but Andy does. ”

"That's right," Lian Yuntian nodded, "the first time he interrogated him, he repeatedly emphasized that Li Jiexi didn't eat his cake at all. ”

"Not only." Wu Zhizhi said, "I saw on the surveillance at the door of Jessica's office that at about five o'clock in the afternoon that day, he had been wandering at the door of Jessica's office, but at that time, Lin Zhongshi happened to be interviewing Jessica, so the curtains in the office were closed, but Jessica came out of the office five minutes later, and then Lin Zhongshi also followed Jessica out, and Andy stood outside Jessica's office door for a long time. ”

"If he insisted on killing Jeffergy Lee, and found out at that time that Jeffrey Lee didn't eat the cake he sent......"

Wu Zhizhi flicked his fingers: "That's what I think, then he will think of another way to make Jessica die, and the birthday party in the evening is the best chance." After Wu Zhizhi finished speaking, he didn't wait for Lin Yintian to speak, and said, "I know, there is no evidence." ”

"Hmm." Even the cloudy sky nodded solemnly.

"However, the forensic doctor will always find evidence, as long as it can be proved that the toxin in Jessica's body is potassium cyanide, it can be confirmed that Andy killed someone."

"Uh-huh......" Even on a cloudy day, he still frowned, looking very heavy.

"Captain, what are you still heavy?"

As he was talking, Cheng Dahei rushed in: "Captain, it's not good!" ”

"Say."

"The Andy you asked me to keep an eye on, I found out that he just bought a ticket to country M, probably trying to escape."
