Chapter 169 The price of a single thought difference
"Peng Lei's case, I also just received a call from Team Guo this afternoon, saying that it has finally been solved!" Cheng Feng first told Jia Yi the result.

When Jiayi heard this, he quickly asked: "Then the real murderer is in line with our deduction?"

Cheng Feng nodded: "That's right! The murderer is Qi Ge!"

"How did Captain Guo handle Qi Ge? Did Qi Ge take the initiative to explain?" Jia Yi became curious.

"How could it be! The people he really wanted to kill have not died yet, do you think he will take the initiative to confess?" Cheng Feng laughed at her naively: "But we are right about one thing, Qi Ge is indeed right for not being able to kill as planned. The death of Zheng Yu was very serious. Later, when he confessed his crime, he also admitted that if he hadn't been arrested, he would have killed Zheng Yu to relieve his hatred even at the risk of being exposed. .”

"Oh my god!" Jia Yi covered his mouth in disbelief: "Although based on inferences, I also suspect that he is the murderer, and the real target is Zheng Yu, but I still can't figure out why he treats Zheng Yu so much. There is such deep resentment, is it because Zheng Yu robbed him of his promotion opportunity?"

"Of course it's not that simple." Cheng Feng shook his head: "After we finished talking with Zheng Yu that day, I called Guo Tian and told him our speculation. He was also at a loss during this time, because The special circumstances at the time of the crime made it impossible for them to find evidence that could directly point to the murderer. After listening to our analysis, he also felt that it made sense, so we discussed it, and finally decided that he would lead someone along the murder weapon and the background of the murderer. Start with the information and try to find the connection with Qi Ge. I have to say that we are very lucky. Guo Tian and the others first investigated the sales channel of the folding fruit knife that killed Peng Lei, and learned that because of that Folding fruit knives are sold at a high price because of their high quality and high cost, and are generally not sold in small stores. Let’s take a look at the consumption of Qi Ge’s bank card. Qi Ge has swiped his card many times before the incident. The storage supermarket has a record of credit card consumption, and the amount is very small, so Team Guo and the others focused on this consumption. After obtaining the monitoring records of the cashier counter from the monitoring room of the supermarket, they finally confirmed that Qi Ge was indeed Bought the same folding fruit knife as the murder weapon."

"Qi Ge is actually quite cunning! He could think of using the paintball gun field as the place to kill, using clothes to cover himself, and in order not to attract attention, he went to a place so far away from home to buy the murder weapon, but Why is he so stupid to choose to pay by credit card?" Jiayi sighed, a little puzzled by this loophole.

Cheng Feng smiled: "After all, this is life, not a detective novel. A person's psychological endurance is limited. When Qi Ge is full of thoughts about how to find the right time to strike, how can he kill Zheng Yu all at once?" At that time, his energy was taken up too much, so it is inevitable that there will be omissions, which is why there is the word "one hundred secrets and one sparse." I never believe that there is a perfect crime in this world."

Jiayi felt that what he said was also reasonable, and nodded for him to continue.

Cheng Feng continued: "On the other hand, we also assisted Team Guo to investigate Qi Ge's living conditions, and finally found that Qi Ge's family life was very happy when he was young, but after his father was accidentally imprisoned, he His mother remarried, and Qi Ge lived with his grandparents since he was a child. It was very difficult, and his father's imprisonment is also very noteworthy. Qi Ge's father was sentenced to death because of intentional injury. There were two other good friends who fought with him back then, but when the court pronounced the verdict, only Qi Ge's father took the main responsibility in his own way, while the other two shirked it in every possible way, so that Qi Ge's father received a heavy sentence, while the other two received light sentences."

"Is this the psychological root of why Qi Ge hates treacherous people so much?" Jiayi suddenly realized.

"That's right," Cheng Feng nodded: "Qi Ge's neighbors and friends have reported that he is a very persistent and persistent person, but he has a special hatred for betrayal. We also learned about the situation of Lu Ling's company, and it is indeed the same as before. As I heard, because Qi Ge joined the company for a special reason, but his own academic level is not good enough, so he has always shown a low self-esteem, and he is not very popular among colleagues. Only Zheng Yu treats him very well. Friendly, I have nothing to talk to him about, so the relationship between the two is good, but after Zheng Yu was promoted, the relationship between the two seemed to drop to a freezing point, and there was no communication at all. Oh, by the way, there is another very important message , after Zheng Yu was promoted, Qi Ge's girlfriend who had been in love for nearly a year suddenly broke up with him."

Jiayi suddenly realized: "There was a psychological shadow in the first place. Zheng Yu stole Qi Ge's work results, which led to sudden changes in his life. These are the driving forces that push Qi Ge into the abyss of crime!"

"That's it." Cheng Feng sighed. This case was not the most difficult and bloody case he had ever taken over, but it was the most embarrassing one. Qi Ge fell into the abyss of crime step by step. The psychological and social factors involved They are both regrettable and helpless, and the deceased Peng Lei is a poor scapegoat: "It's just that Qi Ge never thought that he had calculated thousands of times, but he didn't calculate that before the game started, Peng Lei would do it out of avoidance. Due to Du Yuzhu's selfishness, he suddenly asked Zheng Yu to switch roles, but in the end, Peng Lei became a scapegoat."

"How did Captain Guo get Qi Ge to confess?" Jiayi didn't believe that Qi Ge would obediently confess when the police came to him.

"If you want to talk about this, Team Guo asked me to thank you!" Cheng Feng looked at Jiayi with a smile in his eyes.

Jiayi was surprised when he heard this: "Thank me for what? What did he say?"

"He said he wanted me to thank my smart girlfriend for him!"

Jiayi blushed: "Hey, I promised to be your girlfriend, it seems like it happened just now?"

"But other people don't see it that way. Team Guo has long regarded you as my family member!" Cheng Feng replied with a smile: "When I was talking with Team Guo on the phone, I also emphasized your point of view, that is Qi Ge's knots and the reasons that make him most angry, these will help him to speak. After Guo Dui and the others brought Qi Ge back to the bureau, he was indeed as we estimated at first, insisting that he was the same as Peng Lei. There is no connection, so there is no motive for killing, Team Guo and the others have nothing to do, and finally even moved out the lie detector!"

"How is it?" Jia Yi became interested. Although she often heard about lie detectors, she had never seen them before, so she had a strong sense of mystery, which aroused her curiosity: "Did it come out?"

Cheng Feng shook his head: "It's not that simple. As you know, a lie detector is not perfect for every test. If the other party is mentally prepared, has received special training, or has a relatively strong psychological endurance and is a calm person, Well, lie detectors are often not easy to distinguish between lies and real information. Qi Ge had obviously been mentally prepared for the problems that the police might encounter before that.”

"That is to say, the polygraph doesn't work?" Jiayi looked very disappointed. It was the first time she heard about the real application of the polygraph, and she still expected the polygraph to show its power!

Cheng Feng pampered her and scratched her nose: "Look at you impatient, don't be so anxious to be disappointed! In the end, the polygraph still worked, but what made it work was the strategy you proposed."

"Me?" Jiayi thought Cheng Feng was just teasing her.

"That's right, you mentioned the knot of using Qi Ge and the things that most make him emotionally fluctuate, so after letting Qi Ge rest for a while, Team Guo and the others conducted a second polygraph test on him. But this time they didn't question him as usual, and they didn't focus on the murder weapon and the murder scene. Instead, they started chatting with him about integrity and loyalty. After chatting for a while, they began to talk about his life. Speaking of how unrestrained and unrestrained Zheng Yu was after he was promoted, Qi Ge's mood slowly began to fluctuate. After he became emotional, Team Guo and the others once again brought the topic back to the key information of the case. Once Qi Ge failed to control his emotions well, he reacted to some key information about the murder case, which made the lie detector work."

"Can the result of the polygraph test be a conviction?" Jia Yi asked.

Cheng Feng shook his head: "After all, the results of the polygraph are not [-]% accurate, so if there are only the test results of the polygraph, the evidence is not sufficient."

"Then what should we do?" Jiayi was a little anxious.

"Actually, the practical lie detector is just part of Team Guo's psychological attack strategy. They mainly rely on this to break through Qi Ge's psychological defense. After facing the second lie test result, Qi Ge really messed up. Team Guo and the others took turns to fight He carried out persuasion and education, and in the end Qi Ge couldn't bear the huge psychological pressure, and took the initiative to confess."

Jiayi nodded, expressing his understanding: "After all, it is a human life, or an innocent life. Even if Qi Ge's personality is not sound, his mind is dark, and he is under such pressure, it is estimated that these days will be very painful. After breaking through, speaking frankly may be a kind of relief instead."

"You're right," Cheng Feng confirmed Jiayi's thoughts: "After Qi Ge explained his criminal process, he also told Team Guo that he originally planned to turn himself in after killing Zheng Yu. , It’s just that we took the first step to stop him, and it’s considered Zheng Yu’s life!”

Jiayi couldn't help shivering: "Thinking about it now, I'm really afraid. One person ruined another person's future with a single thought, and aroused the evil thoughts in the other person's heart. Life! If we don't get the right idea, there might be another cold corpse in this world now!"

"Although Zheng Yu escaped danger, I think he will leave a shadow in his heart from now on! Maybe this incident is also a lesson for him." Cheng Feng raised the wine glass in front of him: "Okay, the dust of this case is finally settled , please allow me to toast my smart and beautiful girlfriend, to celebrate our victory together again, and wish us a happy cooperation in the future!"

Under the candlelight, Jiayi's face was extraordinarily rosy, and she also raised her glass to touch Cheng Feng.

On this Valentine's Day night, facing the romantic candlelight, the next time will naturally be spent with the one you love.
