The relationship between Song Guyan and Zhou You is very strange, completely different from ordinary police dogs and trainers.

Song Guyan, who debuted halfway, did not undergo professional training, and many skills were summed up in practice. And Zhou You, with the soul of a human being, is far more intelligent than a police dog. It was precisely because of Song Guyan's unprofessionalism that she was able to give her more freedom to travel.

But tolerance, not connivance. Recently, soybean milk powder has become more and more undisciplined and does whatever he wants, if Song Guyan doesn't give him a tight spell, maybe he will be able to go to heaven in two days.

Just when Song Guyan was giving an ideological education class to soybean milk powder, Xi Yao ran over with a copy of the material.

"Song ...... Sister, Sister Song, the latest laboratory ...... As a result!" Xi Yao ran out of breath, obviously making some new discoveries.

Not every case can be solved in a short period of time, and protracted warfare is the norm. In many cases, no clues are found at the moment, and it may be possible to find enough evidence from other cases after a while. Cases sometimes reach a dead end, and after a long time, the police may be able to get some clues from another inconsequential case.

For example, there was a burglary and murder case in Shanghai before, and no clues were found at the scene. However, when he caught another theft, the thief confessed that an accomplice had drunk too much and talked about the previous case, which allowed the police to quickly lock up the suspect.

Domestic laws emphasize leniency, and meritorious service can be given to a certain degree of mitigation. Don't ignore this rule, which can make many prisoners spit out everything they know.

Song Guyan took the fax from Xi Yao's hand, which was sent by the police department of the Yangtze River Province next to Hucheng.

A simple case of a van with a license plate, but when the Yangtze Provincial Police inquired, they learned that the driver had stolen the car from Shanghai.

While inspecting the vehicle, blood stains were accidentally found on the cushion of the rear seat. The police system is networked, and after comparing the bloodstains, it was confirmed that it was the identity information of Jinzishan, and then it was urgently reported to the Hucheng police.

Song Guyan looked at it roughly: "Have you contacted the captain to find the surveillance video?"

"The technical department is looking for it, but it's been so long that it's been a lot of trouble to figure it out. Xi Yao said with some embarrassment.

The blood stains on the top of the van were found on the mountain, and it was confirmed that the body had been moved. If the van's trajectory can be found in the traffic monitoring, the first scene of the crime can be deduced. For the whole case, it is a heavy key to the truth.

"Let them check first. Song Guyan thought for a moment, "This car was definitely not stolen by accident, it may be that the murderer deliberately let the thief steal this car to achieve the purpose of destroying evidence." ”

"Then guess that our opponent is a very cautious guy with a certain amount of anti-reconnaissance capabilities. Song Guyan said with high spirits.

Zhou You was lazily lying on the side, it seemed that the shovel officer had no time to take care of himself.

The technical section determined the time and place of the stolen vehicles with the comrades in the Yangtze Province, and then coordinated with the traffic management department to review the contents of a large number of traffic probes. Although it is possible to brush off a lot of useless content through the power of technology, it still requires a lot of manpower to identify it.

During this time, Song Guyan and Xi Yao decided to visit the place where the theft was stolen and if there were any witnesses.

Zhou You's heart was also very bitter, and he followed Song Guyan back and forth. However, he knew very well that he had just slipped out, and Song Guyan would definitely not let him stay in the police station, so he simply slept on the back seat.

Song Guyan's opponents were far more vigilant than they imagined. The only thing that is certain is that the car drove into the community, but the surveillance of the community did not take pictures of the specific appearance of the driver. The colleagues in the technical department also had a headache, the car seemed to fall from the sky, and it was impossible to find its origin.

In any case, it was determined that the community was the first scene of the crime, so Song Guyan and Xi Yao decided to search Jinzishan's house again.

Different from the last questioning, with certain evidence, the police applied for a search warrant, and a group of people conducted a carpet search of the villa.

Tong Menglin had the intention to stop it, but she was directly pulled aside by the policewoman.

The order of the compulsory search did not allow her to refuse or resist. Perhaps knowing this, Tong Menglin quickly calmed down.

The police who searched the villa naturally carried sufficient equipment, but the search of police dogs was also very necessary, which could make up for some deficiencies in technical equipment.

Zhou You happened to be at the scene, so there was no need to trouble other police dogs.

The smell in the room made him feel that the range was almost dispersed, although there were still some, it was still within the range of tolerance.

When he saw the street trick before, Zhou You had a guess that Yang Zhuo was in this villa, probably to block the police's sight. He left so many clues just to make the police ignore some small clues.

To vacate the cage for a bird is to remove all traces of the previous person, and then introduce the traces of the new person, so that the police can focus on the latter.

If Zhou You's guess is correct, Tong Menglin is definitely an insider, and even a direct participant in the murder case.

Zhou You glanced at Tong Menglin, who was expressionless, and began to search room by room.

The last time was not enough, and Zhou You only found the razor left by Yang Jie by chance. This time he had a lot of time, and he was able to search carefully.

Towels in garbage cans, short hair on carpets, fingerprints on wine bottles and glass tables, and a large amount of physical evidence found by the police who traveled around and at the scene, but it still needs to be sent to a forensic laboratory for testing.

Zhou You felt that it was not so simple, these physical evidence were too easy to find, as if they were placed under the spotlight, and they were deliberately not cleaned up. It is estimated that the test is also Yang Jie's information.

Tong Menglin asked her nanny to take a vacation before, which may have been deliberately arranged.

Scratching his feverish head, Zhou You felt that his mind was trapped, and there was no way to get out, obviously a big hole that he had dug himself.

Zhou You glanced at the living room upstairs, and the two policewomen looked at Tong Menglin sitting on the sofa one left and one right, to prevent her from making any changes.

Tong Menglin had no sense of movement at all, her face was expressionless, and she directly ignored the police walking back and forth in the room, and she didn't know what she was thinking.

It's so calm, not at all like when I first saw her, I was so excited.
