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

four o'clock in the evening

"Dong dong dong" The rapid knock on the door woke Luo Fei from his sleep.

Luo Fei already had some guesses in his mind.

He opened the door, and outside the door were his aunt and Wu Yan.

Auntie's eyes were red and her face was full of anxiety, and Wu Yan's face was also full of anxiety.

"Mom, what's wrong with auntie?" Luo Fei already guessed it in his heart, but he still asked.

"Xiao Fei, several police officers just rushed into the house and arrested Xiao Yu. They also said that he killed someone. Go and have a look. There must be some misunderstanding. Although Xiao Yu usually makes some mistakes, But how could he kill someone?" said my aunt in tears.

With.

"Xiao Fei, go and see what's going on. Is there any misunderstanding?" Wu Yan next to her also urged Luo Fei.

Luo Fei knew that since the criminal police team suddenly arrested someone, it meant that the criminal police team had completed DNA and fingerprint matching, but Luo Fei still nodded and said: "Okay, I'll go take a look. Mom, you and your aunt are waiting at home." Bar."

Suddenly remembering something, Luo Fei asked: "By the way, why are you the only aunt? Where's the uncle!"

"That goddamn uncle of yours is at home. I asked him to come over. He said that the police would not arrest people for no reason. He also said that he didn't have the son of a murderer, so he just refused to come over." When it came to my uncle, my aunt was full of it. angry.

"Mom, aunt, you two should go home and have a look. I'm afraid something might happen to uncle." After thinking about it, Luo Fei reminded, although the possibility is very small, his son committed a murder and was arrested by the police. If something like this happens, , who knows whether uncle can think about it or not.

Then Luo Fei put on his clothes and rushed to the criminal police team. He also wanted to know the specific situation.

When Luo Fei arrived at the front desk of the criminal police team, there was no one at the front desk. When Luo Fei was wondering who to look for, the short-haired criminal policeman came out with a record book.

Luo Fei knew that the other party's name was Yang Su, the captain of the Criminal Police Action Squadron. The two had never communicated with each other, but counting from the first Gu Youguo case to the Su Xiao jumping off building case and this case, the two had met three times. .

"Captain Yang." Luo Fei quickly stepped forward to say hello.

"Luo Fei, why are you here?" Yang Su also saw Luo Fei. He had a good impression of Luo Fei. Luo Fei was able to help them every time he solved the case.

"Team Yang, did the DNA and fingerprints match?"

"The fingerprints are not Wu Yu's, but Wu Yu's DNA comparison is exactly the same as a set of DNA collected at the scene. Now the captain and the others are interrogating Wu Yu! Let's go over and see what's going on."

Luo Fei followed Yang Su to the door of the interrogation room, where Yang Mei and the others were present.

In the interrogation room, Wu Yu was handcuffed on a chair. Looking at his pale face and trembling hands, it could be seen that he was frightened at this moment. The person in charge of the interrogation was Zhao Donglai.

Yang Mei and others also saw Luo Fei.

Yang Su asked Luo Fei to stay outside with Yang Mei and the others, while he entered the interrogation room with the record book.

The interrogation about Wu Yu was basically not difficult. Zhao Donglai made Wu Yu explain everything in less than five minutes.

They were the ones who killed Tang Quan Quan. There were four of them, Wu Yu, Zhou Xiaotiao, Ma Hu, and Huang Bin. All four of them had no jobs and usually hung out on the street.

That day they got interested and wanted to go to the mountains to drink, so they took two bottles of wine and some snacks and went to Walnut Mountain.

When they passed by Tang Quanquan's house on the mountain, Tang Quanquan's dog kept barking at them. They felt that the dog was very annoying. At that time, Zhou Xiaotiao even picked up a piece of wood to beat the dog.

Later, they found a nice place, started eating, drinking a bottle of wine, and chatting and bragging. I don’t know who started it. Suddenly, several people started talking about the heroes of the past. They ate meat and drank wine. There were so many Brave and powerful.

As he talked, Ma Hu felt that just drinking without meat was not enough. He said that if there was meat, they could eat meat and drink like the heroes in the past. Several other people also felt that it was a pity that there was no meat.

Suddenly Zhou Xiaotiao said, wasn't there a dog next to that house just now? He suggested stealing the dog and roasting it.

Several other people were also very moved after hearing this, so together they decided to steal the dog.

So a few of them returned to the house. The owner of the house was not at home. When the dog saw Zhou Xiaotiao and others, it barked again.

Ma Hu and Wu Yu took the prepared wood and hit the dog's waist hard. The dog was knocked down on the spot.

They then took the dog away with the leash.

After taking care of the dog, Wu Yu and the others began to barbecue and drink beer and feel very happy.

At around four o'clock in the afternoon, after eating the dog meat and drinking the two bottles of wine they brought, Wu Yu and the others were ready to go back.

On the way back, I passed Tang Quanquan's house.

Tang Quanquan had already returned home and found that his dog was missing. He searched for it for a long time but could not find it.

When they saw Wu Yu and the others, they asked them if they had seen his dog. Wu Yu and the others would definitely deny it, but they did not expect that Zhou Xiaotiao kept playing with the dog leash and did not lose the leash.

Tang Quanquan saw the dog chain on their hands and knew that the disappearance of the dog must be related to Wu Yu and the others, so he sternly asked Wu Yu and the others where his dog had gone. He also said that if Wu Yu and the others did not reveal the whereabouts of the dog, they would be killed. Four people's legs were broken.

Wu Yu and the four of them had just drank a lot of bottles of wine, and they were also feeling drunk at this time. They were very brave. You, an old man, dared to yell at us loudly, so you said that the dog had been killed by us, roasted and eaten.

When Tang Quanquan heard that the dog he had worked so hard to raise had been killed and eaten by the little bastards in front of him, he was shocked and angry. He stepped forward and slapped the sloppy dog ​​in front of him, and cursed them as beasts, not human beings. No one teaches.

Now Tang Quanquan completely angered Wu Yu and others. They stepped forward and pushed Tang Quanquan to the ground, took off Tang Quanquan's shoes carelessly, and slapped Tang Quanquan in the face.

However, Tang Quanquan was also tough-talking, his face was swollen from the beating, and he kept scolding him, and the more he scolded, the more unpleasant it became.

Wu Yu and others also got angry and said to Tang Quanquan, let's see how tough your mouth can be, so they carried Tang Quanquan into the house.

Zhou Xiaotiao tied a dog chain around Tang Quan Quan's neck, took off Tang Quan Quan's clothes and pants, pulled Tang Quan Quan like a dog, rode him like a dog, and then beat Tang Quan Quan severely with the chain.

But no matter how tortured, Tang Quanquan was stubborn and still cursed Wu Yu and the others.

Wu Yu was originally sitting on the camp bed. He had just drunk a little too much and his head felt a little uncomfortable. Then for some reason, Wu Yu touched a rusty wrench.
