Solving the case: Combining the police dog's olfactory genes at the beginning

In the Criminal Police Team, a group of offices, Yang Su and Wang Lei were discussing and analyzing the case.

"Team leader, according to the descriptions of people familiar with the deceased, the deceased was usually upright and kind-hearted. I have never heard anyone say that he had any conflicts with anyone. Therefore, I don't think the hypothesis of vendetta is very reliable. We are sure to do it. Investigate from this aspect?" Wang Lei asked doubtfully.

"Not necessarily. Hatred that can be put on the surface will not be fatal. The most deadly hatred that can kill people is hidden deep in the heart and unknown. Maybe the burglary was deliberately disguised by the murderer. The murderer wanted to use this method to conceal his true purpose, so I think we need to carefully investigate the social network of the deceased." Yang Su shook his head and said seriously.

"The team leader is right. Team leader, where do we start the investigation?" Xia Zhengze asked.

Hearing Xia Zheng's words, Yang Su frowned and fell into thinking. Then he looked at Wang Lei and others and asked, "What do you think, where should we start the investigation?"

In an instant, Wang Lei, Xia Zheng and the others looked at me, and I looked at you, but for a moment they had no idea.

At this time, Yang Su couldn't help but miss Luo Fei. If Luo Fei was here, he should be able to give good suggestions.

Just as Yang Su was about to speak, his cell phone on the table rang.

It was Zhao Donglai's call.

"Captain Zhao, do you have any orders?" Yang Su asked.

But the next moment when Yang Su heard Zhao Donglai's words, he immediately went numb.

Luo Fei and the others caught the murderer.

"Team leader, what's the matter with Captain Zhao's call?" Wang Lei couldn't help but ask when he saw Yang Su stunned.

"Luo Fei and the others have caught the murderer." Yang Su glanced at Wang Lei and the others and said calmly.

"This..." Wang Lei was stunned, his mouth slightly opened, and his entire facial expression was frozen instantly.

"How long has it been? Luo Fei has solved another case like this? Do you want to be so exaggerated? Why does it feel like Luo Fei is the one solving the case in the entire criminal police team now." Xia Zheng looked in disbelief.

Looking at the expressions of the team members, Yang Su was not surprised at all.

On Luo Fei's side, after confirming that Cao Dong was not a suspect, Luo Fei took Lin Gang back to the criminal police team as soon as possible.

Interpol captain Zhao Donglai immediately waited at the gate of the Interpol team for Luo Fei to bring Lin Gang back.

After receiving a call from Luo Fei, saying that he had caught the murderer, Zhao Donglai became increasingly grateful for his wise decision in recruiting Luo Fei from the police station to the criminal police team.

Luo Fei brought Lin Gang back to the criminal police team, and Zhao Donglai asked Luo Fei to interrogate Lin Gang immediately.

interrogation room

Lin Gang's hands were handcuffed, and the expression on his face was very panic. At the moment when he was caught and brought into the interrogation room, Lin Gang truly realized his fear and fear.

Luo Fei was in charge of the interrogation, and Sun Jun helped Luo Fei record it.

"Tell me, how did you kill Cheng Zhiyou?" Luo Fei asked with a serious face and a cold voice. Even though Lin Gang had just been caught, he was still in a panic and uneasy mood, and did not give him any time to think and calm down. Taking advantage of the opportunity, Luo Fei decided to continue to put pressure on Lin Gang and break through Lin Gang's psychological defense in one fell swoop.

"I...I didn't kill him, I just stole the money, I didn't kill him." Lin Gang said nervously.

"Lin Gang, I advise you to tell the truth honestly. At this time, do you think there is still meaning in sophistry? If I were you, what I should be thinking about now is not how to make excuses, but should be thinking about taking the initiative to confess and try to exaggerate the deal. ." Luo Fei said coldly.

"I really just stole money, I really didn't kill anyone." Lin Gang said with some lack of confidence.

"Stealing money? What happened to the knife in your hand? Do you think our police are fools?" Luo Fei scolded angrily.

"That knife...that knife..." Lin Gang still wanted to find a reason, but he was so panicked now that his mind went blank for a moment, and he couldn't think of any reason at all.

"That's enough, stop quibbling. We already have conclusive evidence. It's useless for you to quibble." Luo Fei interrupted Lin Gang by yelling.

Lin Gang was instantly startled, and his face became paler.

Then Lin Gang lowered his head and said in frustration: "I tell you, I tell you everything, I killed Cheng Zhiyou, but I really never thought about killing him before. I really just wanted to steal money before, but I don't know why Cheng Zhiyou will come back suddenly, Cheng Wei has clearly said that Cheng Zhiyou will not come back."

Then Lin Gang explained all the details of the entire case. On the night when Cheng Zhiyou won the 100,000 yuan prize, Cheng Wei, Lin Gang and Cao Dong had a party together. During the period, the three of them talked about the fact that Cheng Wei's father, Cheng Zhiyou, had won the prize. For Cheng Wei When his father won 100,000 yuan, Lin Gang was envious and jealous. He was envious and jealous because he was not the winner. He also told Cheng Wei that it would be great if he won 100,000 yuan, so that he could have money to buy a car. It's here.

After the dinner party, Lin Gang and Cao Dong separated from Cheng Wei and went home. Lin Gang had just returned to Sunshine Community to separate from Cao Dong when Cheng Wei called.

Cheng Wei told Lin Gang that he was just outside their community and he wanted to discuss something with him. Lin Gang went out without thinking much and met Cheng Wei at the gate of Sunshine Community.

Cheng Wei asked Li Gang if he wanted to get rich as soon as they met. Lin Gang felt baffled at the time and thought Cheng Wei was teasing him. Who doesn't want to get rich?

But then Cheng Wei told Lin Gang that his father kept the 100,000 bonus he just won at home, and he wanted Lin Gang to steal the money and split the stolen money equally between them.

When Lin Gang heard what Cheng Wei said, he felt that Cheng Wei must be joking with him. How could anyone steal money from his own family? But then Cheng Wei said that Zhao Yi was pregnant and needed a sum of money for surgery, but Zhao Yi He didn't want his family to know about it, so he came up with this idea.

Lin Gang didn't take this matter seriously before, but now after hearing what Cheng Wei said, Lin Gang became serious.

He asked Cheng Wei if what he said was true. Cheng Wei nodded, and then Lin Gang was moved. After all, it was one hundred thousand yuan, and he thought that Cheng Wei asked him to steal the money. Even if he was really caught, Cheng Wei Is it possible that the great father would send his son to prison?

Then Lin Gang asked Cheng Wei how to steal it. Cheng Wei told Lin Gang that on the night of the second day of the Lunar New Year, his father was not at home to pay New Year greetings. He gave Lin Gang a key to his house and asked Lin Gang to steal it from behind the community at ten o'clock in the evening. Climb over the railing, open the door and enter the house, then go to his father's room and steal the 100,000 yuan from the bottom drawer of the closet.

Cheng Wei also asked Lin Gang to wear gloves to avoid leaving fingerprints, and to check the peepholes and door handles to show signs of a thief entering the house.

Lin Gang agreed.

At ten o'clock in the evening on the second day of junior high school, he climbed into the community through the iron railing behind the community and opened the door with the key. As expected, Cheng Wei's father was not at home. Lin Gang found 100,000 yuan in cash in the bottom drawer of the bedroom wardrobe. bag.

Everything was as Cheng Wei said, he got the money successfully, and then just when Lin Gang got the money and was about to leave, the door was suddenly opened, and then the lights in the room were turned on. The next moment, Lin Gang and Cheng Zhiyou Eyes facing each other.

At this moment, Lin Gang's head was blank. He was in a panic. Without even thinking, Lin Gang subconsciously took out the dagger he had used to embolden others and rushed towards Cheng Zhiyou, fiercely aiming at Cheng Zhiyou. stabbed into the stomach.

Cheng Zhiyou almost didn't react before he was hit by a knife. However, this knife was what Lin Gang usually used to scare people. The knife was short in size, so the blow did not cause any substantial damage to Cheng Zhiyou.

Cheng Zhiyou grabbed Lin Gang's shoulders tightly. In panic, Lin Gang drew out his knife and stabbed and chopped at Cheng Zhiyou again.

When Cheng Zhiyou lost too much blood, lost consciousness and let go of his hand, Lin just ran out of the room in a panic and ran back home.

When Lin Gang got home, his first reaction was to run away before the police could react. After all, if he killed someone, he would be jailed for life if he was caught, even if he was not shot immediately.

Just when Lin Gang was about to pack his things and run away, he didn't expect a call from Cheng Wei.

Lin Gang was initially prepared not to answer the call, after all, he had just killed Cheng Wei's father, but then he thought again, Cheng Wei knew that he was going to steal money, and if he told the police about it, Then he will definitely become a wanted criminal. Then he can still run there, and it was Cheng Wei who asked him to steal the money. Now he accidentally killed his father. He is responsible for this, but Cheng Wei also escaped. Without responsibility, Cheng Wei wouldn't be able to live well if he was caught.

Thinking of this, Lin Gang answered Cheng Wei's call and took the initiative to tell Cheng Yuan about it.

But when Cheng Wei heard Lin Gang say that he killed his father, he didn't show too much excitement. He calmly asked Lin Gang what he wanted to do now. When Lin Gang saw Cheng Wei's attitude, he didn't seem to want to seek revenge from him. , just told Cheng Wei that he was ready to run away.

The next moment, Cheng Wei said that he couldn't escape now. If he escaped now, he would immediately become the focus of the police's attention. Once the police targeted him, he would be caught even if he ran all over the world. Cheng Wei asked Lin Gang to escape now. Stay calm and don't do anything. The police may not be able to find him, so don't mess up your position first.

When Lin Gang thought about it, it seemed that this was true, so he gave up the idea of ​​​​running away.

"This is the whole process." Lin Gang told the entire crime process in one breath.

After Luo Fei listened, he thought about the black energy on Cheng Wei's head and the ferocious villain. He was almost certain that Cheng Wei's real intention in letting Lin Gang steal money was to let Lin Gang kill his father.

"By the way, did you find anything when you ran away today?" Luo Fei suddenly remembered and asked.

"When Cao Dong and I came back, I saw a policeman outside the community, a criminal policeman. I thought that he must have been exposed, so I ran away."

"Who is it? How did you know it was the detective? Did you know him before?" Luo Fei asked with a frown.

Lin Gang thought for a while and said: "It's the tall and thin guy. I saw him at the party before. My friend introduced him to me and said he works in the criminal police team."

Tall and thin, Luo Fei knew without even thinking that it was Zhao Cheng, and only Zhao Cheng was tall and thin.

outside the interrogation room

"So the deaths of Cheng Wei and Cheng Zhiyou are inextricably linked." Zhao Donglai frowned and said to Yang Su next to him.

"Indeed, as Lin Gang said, there are many doubts about this home invasion and robbery case. The first thing that doesn't make sense is that Cheng Wei told Lin Gang that Cheng Zhiyou would not come back on the night of the second day of the second grade, but Cheng Zhiyou did go home. At this point Was it an accident or Cheng Yuan did it on purpose? If Cheng Wei really did it on purpose, then..." Yang Su stopped here.

"Yes, judging from Lin Gang's confession just now, Cheng Wei's motive for asking Lin Gang to steal money in the room is very suspicious."

At this time, Luo Fei and Sun Jun walked out of the interrogation room after the interrogation was over.

"Team Zhao, team leader." Luo Fei greeted Zhao Donglai and Yang Su.

"Luo Fei, what do you think about the deceased's son Cheng Wei?" Zhao Dong came to look at Luo Fei and asked.

Luo Fei thought for a moment and then said: "Captain Zhao, actually I have a feeling that the death of the deceased Cheng Zhiyou was not an accident, but a murder that had been planned long ago."

"What do you mean, Lin Gang's robbery and the murder of Cheng Zhiyou were all premeditated by Cheng Wei!" Zhao Donglai asked.

"Yeah." Luo Fei nodded. From the ferocious villain on Cheng Wei's head, Luo Fei was almost certain that Cheng Wei had already planned to let Lin Gang break into the house and rob him, and then use Lin Gang to kill Cheng Zhiyou.

"If Cheng Wei really murdered Cheng Zhiyou, how much hatred would there be?" Yang Su said with emotion.

Zhao Donglai thought for a while, and then said: "Luo Fei, take the people now, arrest Cheng Wei immediately, and interrogate him immediately."

Luo Fei frowned. From what he had so far, he could only prove that Cheng Wei instigated Lin Gang to steal money. As for Cheng Wei's premeditated death of Cheng Zhiyou, there was no evidence at all. Even if Cheng Wei was arrested, Cheng Wei would probably not Will admit it.

Zhao Donglai then looked at Yang Su, "Yang Su, please take someone to investigate. What is the conflict between the deceased and Cheng Wei, father and son? At the same time, investigate clearly, where did the deceased go on the second day of the second grade? What did he do? ."

"Team Zhao, didn't Cheng Wei say that Zhao Yi was pregnant and had no money for surgery, so he thought of asking Lin Gang to steal the money? Can we check whether Zhao Yi is really pregnant?" Luo Fei reminded.

"Yes, we need to find out this point as well." Zhao Donglai nodded affirmatively.

According to Zhao Donglai's instructions, Luo Fei led his men to arrest Cheng Wei immediately.

and conduct interrogations.

"Do you know why I brought you here?" Luo Fei asked calmly, staring at the handsome, calm-looking Cheng Wei in front of him without any panic at all.

Cheng Wei shook his head.

"We have arrested Lin Gang. Lin Gang told everything. It was you who asked Lin Gang to steal money at home. Lin Gang would kill your father. Do you admit this?" Luo Fei asked.

"Yes, it was me. I asked Lin Gang to steal the money, but I didn't expect such a thing to happen. If I had known that this would happen, no matter how much of a bastard I was, I would never have let Lin Gang steal the money. "Cheng Wei's eyes turned red instantly as he spoke, and he looked very sad.

Luo Fei felt that Cheng Wei's sadness was not all staged, there should be some real sadness in it.

"You said that Zhao Yi was pregnant and needed surgery. You didn't want your family to know about it. You asked Lin Gang to steal money because he was in urgent need of money. Is this true or false?" Luo Fei continued to ask.

Cheng Wei shook his head, "I lied to Lin Gang. In fact, Zhao Yi was not pregnant. I was short of money. I asked my father for money, but he didn't give it to me, so I made up an excuse to lie. Lin Gang went to steal the money, and the stolen money was divided in half.”

I was late to update when I returned to my hometown today. I coded these 4,000 words on the high-speed train. It was so uncomfortable.
