After listening to Zhu Dayong's story, Liu Li couldn't help frowning: "Since the Tibetan mastiff you raised is very repulsive to outsiders, it means that the thieves used a certain method to first put those Tibetan mastiffs into a deep sleep, and then stole them while the Tibetan mastiffs were unconscious."

As you said just now, those Tibetan mastiffs are more than one meter in size, and if you want to transport six huge Tibetan mastiffs, ordinary cars will definitely not work, so if you infer this, the vehicle used by thieves to steal dogs should be a van.

Later, let's check the surveillance at the nearby intersection to see if there are any suspicious vans coming in and out of your village after you leave home in the morning until you go home. I'm sure one of those vans must have been driven by a thief. ”

"Comrade police officer, there is no surveillance near the intersection of our village." After Zhu Dayong said this, he pondered for a while, and couldn't help asking: "Forgive me for taking the liberty, how do you know that the vehicle that stole the Tibetan mastiff is a van?"

There were no car marks left at the scene, and no one around saw the thief's vehicle, if the thief drove another vehicle to steal the Tibetan mastiff, and you used the van as the direction of investigation, would it be a waste of time? ”

Hearing Zhu Dayong's question, Liu Li explained to him: "There will be no mistake, the thieves definitely put those Tibetan mastiffs in the van, and if you investigate in this direction, there will definitely be a harvest."

Because of the limited space of the sedan, it is impossible to load the huge Tibetan mastiffs, while the motor tricycles and agricultural six-wheelers, although convenient for loading the Tibetan mastiff, there is only one compartment in the back of these cars, and there is no shelter on it.

If the thieves use that kind of car to load the Tibetan mastiff, afterwards, they must cover the car with objects, otherwise they will be seen by passers-by, which will delay the time, so that the vehicle is not suitable for transporting the Tibetan mastiff.

Although Iveco and commercial vehicles are also suitable for loading Tibetan mastiffs, that kind of car is too eye-catching when it comes to this small village, and it is easy to arouse the curiosity and attention of the villagers, so it is impossible for thieves to choose that kind of vehicle to steal Tibetan mastiffs here.

In this way, the space is large enough, not dazzling, and it is convenient to load the Tibetan mastiff, and it is not easy to attract the attention of the villagers, only the van remains, because this kind of vehicle is very common in the countryside, even if the thief parks the van on the street, as long as it does not obstruct the road, it will not attract the attention of the villagers. ”

Speaking of this, Liu Li paused, and then continued: "As for monitoring, since there is no monitoring installed at the intersection near your village, then we can only use stupid methods, first, you go to the village to inquire first, and see if the villagers have noticed that you have stopped in front of the van?"

Second, it is a needle in a haystack, the road at the entrance of your village leads to the township to the south, and the county leads to the north, and the exit of your village is in the middle of this road.

I remember that at the intersections at both ends of this highway, high-definition monitoring probes are installed, and we will call up the monitoring of this highway when we go back, and check all the vans driving on this highway. ”

"How do you find this? With so many cars coming and going, how do you know which van has come to our village? Hearing Liu Li's words, Zhu Dayong looked at Liu Li with some doubts.

"How do you find it? Take your time. After speaking, seeing that Zhu Dayong's expression was still a little puzzled, Liu Li had to tell him: "From the monitoring office in the north to the monitoring office in the south, it takes about ten minutes to drive."

We start to access two surveillance cameras from the time you leave the house, whether it is from north to south, or from south to north, as long as the van appears in the two surveillance cameras in about ten minutes, it means that there is no problem with the car.

For example, if a van travels from north to south, the first minute, it appears in the monitoring screen of the north intersection, and when it is about ten minutes, the car appears in the monitoring screen of the south intersection, which means that the van has been driving normally without pausing.

On the contrary, a certain van appeared in the surveillance screen of the north intersection from the first minute, but after 20 minutes, the car did not appear in the surveillance screen of the south intersection.

If the car didn't break down on the road, it means that the car had come to your village in the middle of the road, so it was delayed, and the car was the suspicious vehicle we were looking for. ”

After explaining, Liu Li walked into the courtyard alone, and after careful investigation, there were still no clues, looking at the iron cage that was opened, Liu Li couldn't help but say to himself:

"Since the other party is here to steal the mastiff, it will definitely not stay too long, and the crime will only take a few minutes at most, if the thief stays too long, it may attract the attention of the villagers.

But in such a short period of time, what methods did the thieves use? Before the Tibetan mastiff roared, what about those Tibetan mastiffs who subdued them? Unless drugs are used, the Tibetan mastiffs cannot be made to resist.

But these Tibetan mastiffs never eat food given by strangers, so how did the thieves feed the Tibetan mastiffs with medicine? Also, if the thieves feed the Tibetan mastiff medicine, the Tibetan mastiff will definitely roar when it hears something strange, because the canine has the most sensitive sense of hearing and smell.

As long as these Tibetan mastiffs continue to roar, then the nearby villagers will come to check the situation after hearing the movement, and they will be curious, but why did these Tibetan mastiffs not make any sound from beginning to end? ”

Because the value of these Tibetan mastiffs is too huge, the value of each Tibetan mastiff is close to 100,000 yuan, which has reached the scope of a criminal case, so after Liu Li investigated the scene, he reported the case to Du Zhiqing and asked the criminal police team to come over.

Half an hour later, Cheng Bin, the captain of the criminal police brigade, led two members of the criminal police team to the scene, and after seeing Liu Li, Cheng Bin was stunned, this time he did not rush to investigate the scene, but walked to Liu Li's side: "Such a coincidence? It's you who went to the police to investigate the case again, how about it? Is there a catch? ”

After hearing this, Liu Li shook his head: "There is nothing to gain." Then, he told Cheng Bin about his present and reasoning, and after speaking, Liu Li concluded:

"This gang of thieves should be veterans, they chose to commit the crime during the day, and after committing the crime, there were no clues left at the scene, which shows that this gang of thieves is bold and careful, and the average novice does not have such a good psychological element."

"Oh? Is it? You just used the word "this gang", how do you know that this is a group of people gathering to commit a crime? And not someone who committed the crime independently? Cheng Bin asked rhetorically.

"Cheng Da, you're too calm, aren't you? Could it be that you know the suspect's clues? Seeing that Cheng Bin did not enter the hospital to investigate the scene, but stood at the door and asked himself, Liu Li was a little surprised.

"Have you answered my question yet?" Cheng Bin did not answer Liu Li, but continued to ask about the topic just now.

Seeing this situation, Liu Li seemed to understand something, pondered for a while, and said to Cheng Bin: "The reason is very simple, a total of 6 Tibetan mastiffs were stolen in this case, Tibetan mastiffs belong to giant canine animals, and an adult Tibetan mastiff weighs about 100 catties, and individual Tibetan mastiffs can even weigh more than 200 catties.

The Tibetan mastiffs stolen in this case were all adult Tibetan mastiffs, huge in size, and weighed about 100 catties. The thieves stole 6 Tibetan mastiffs at once, and if the thief was alone, he would not be able to transport them to the car because they were too heavy.

If you want to transport the Tibetan mastiff to the car quickly, and adjust the posture of the Tibetan mastiff in the van, it takes at least three people, plus the driver and the person in charge of the wind, I judge that this gang of thieves has at least 5 people. ”
