Looking at this messy cemetery, I said to Lao Lu: "I understand now that it is not the people who have enmity with the Xue family who destroy the ancestral tombs of the Xue family, but professional tomb robbers. ”

Lao Lu also looked at the damaged cemetery and said, "Tell me about your speculation." ”

I took a few steps forward, pointed to the gap next to the tombstone, and said, "Schrödingli, do you remember the two steles next to the tombstone, and on the steles are the two gods who guard the mausoleum? ”

Xue Dingli looked at the location of the stone tablet with red eyes, and nodded effortlessly.

I said, "Lao Lu, you also said before that this cemetery looks very old and should belong to the ancient monuments. I have also carefully observed the stone monuments in the cemetery, and the carvings are so natural and ingenious that they must have been made by skilled craftsmen of the time. A stele like this, I'm sure, must have been targeted by tomb robbers who knew the goods. ”

Lao Lu frowned and asked, "Are you sure that this ancestral tomb of the Xue family was destroyed by tomb thieves?" ”

I nodded and said, "Yes." Their goal was to steal the old, valuable tombstones. ”

Lao Lu said: "I still have a doubt, why don't these tomb robbers steal the cemetery when they destroy it first, but they only steal it the second time?" ”

I said, "I think these grave robbers must be repeat offenders and have strong anti-reconnaissance capabilities. The first time they destroyed the cemetery, they wanted to probe the truth and see if the cemetery was being cared for. In the past few days, some grave robbers must have returned to the cemetery and found that no one had renovated the cemetery, thinking that it was a deserted cemetery, so they took advantage of the heavy rain to commit theft again. I think there are two reasons why this group of tomb robbers took advantage of the heavy rain to commit theft, one is that the heavy rain can wash away most of the traces of the crime, and the other is to make the descendants of the tomb think that the collapse of the cemetery was caused by the heavy rain. ”

Lao Lu nodded: "These tomb robbers really have enough ghost eyes. ”

After I finished speaking, I walked around the cemetery, but because of the heavy rain, I didn't find any valuable clues.

I walked up to Lao Lu again and said, "Sure enough, the heavy rain still made all the footprints at the scene. Even so, I was able to identify a few important pieces of information. ”

Lao Lu looked at me and said, "Let's hear it." ”

I said, "The first one I said before is that there must be a lot of people involved in this tomb robbery. In addition to the destruction of a large number of cemeteries, they also had to transport the two stone tablets weighing 1,000 catties. Of course, the reason why no traces of transport were found at the site is easy to explain, and that is that the two steles were carried away by man. Although the heavy rain washed away the footprints on the soil, some of the fallen weeds could still be seen as trampling marks. ”

Lao Lu looked at me and nodded.

I continued: "Second, it is obviously impossible to carry such a heavy stele away from the mountain by manpower alone, so this group of tomb robbers obviously owns a car. So the way this group of tomb robbers transported the stele was obviously to lift the stele to a car parked in the distance through manpower, and then use the car to completely transport the stele away. Following the direction of the weeds, I believe I can find a place where the grave robbers parked. ”

Lao Lu immediately said: "Then hurry up and find the car stop." ”

Following those fallen weeds, we found a machine farming road in the mountains about two kilometers away from the ancestral tomb of the Xue family.

I asked Schrödingli, who had lived here for a long time, "Can this machine plow road go down the mountain?" ”

Xue Dingli said: "This machine ploughing road is the road used to transport wood in the forest farm in the past, and it can lead to National Highway 318. However, after the closure of the forest farm, there are almost no vehicles coming up the road. ”

I looked at the rut marks on the road and said, "The rut marks are still clear, apparently from the grave robbers' vehicles." Based on what I know about the tire pattern, I'm sure it's a rut mark left by a light truck. ”

I asked Xue Dingli again: "How far is this machine ploughing road from National Highway 318?" ”

Xue Dingli thought for a while and said, "It's less than five kilometers. ”

I then said, "Lao Lu, you take Xue Dingli back, drive the police car and wait for me at the exit of the machine farming road, and I will walk over to check the situation along the way." ”

Under the leadership of Xue Dingli, Lao Lu and several criminal policemen took the path and walked in the direction of the parked police car. I, on the other hand, walked along the muddy mountain road.

Of course, my purpose in doing this is not that I have any leisure and leisure, walking among the green mountains and green waters to enjoy the unique scenery. On the contrary, I had to be highly focused, looking along the way for clues that the tomb robbers might have left behind.

These clues could be drink bottles, cigarette butts, or napkins thrown from a car window.

After walking this five-kilometer journey, I really collected a lot of suspected physical evidence in my plastic evidence bag along the way.

Among them were four cigarette butts, three of which were Yuxi cigarettes, and they appeared not far from each other. I was able to deduce that the three cigarette butts might have been thrown out of the car by the tomb robbers. The three of them smoked cigarettes almost at the same time, but because they smoked at different speeds, they threw the cigarette butts out of the car at different times. But even so, the speed at which they smoked was not too different, so the distance between the three cigarette butts after being thrown out of the car window was not too far.

There was also a bottle of Red Bull can, which was found on the left side of the road in the direction of the downhill, and there was still a residual drink in the opened can, apparently the can was not thrown for long. Because it was found on the left side of the road, I presume that the driver was driving at night and drank it for refreshment.

Three napkins were also found, all of which had obvious oil stains, which were of the same red chili oil. It seems that it should be left by the tomb robber gang after eating the same kind of food with chili oil together after committing the crime, and then wiping their mouths.

DNA can be extracted from these physical evidences. I think that such a large tomb robbery gang must be organized by professional criminals, and such a well-planned tomb robbery operation must be a veteran of tomb robbing. Then there is a high probability that the person has a criminal record, and it is very likely that the person can be found from the DNA comparison.

I sent the evidence to a forensic center, and the DNA comparison results came out quickly.

On one of the Yuxi cigarette butts, the technician extracted DNA that belonged to a man named Zhang Zhaochai.

Zhang Zhaochai is 52 years old this year, and his criminal resume has continued from the time he was still a minor.

And in his 'glorious history', those pickpocketing and robbery are only petty fights, he once went to prison three times for tomb robbery and selling cultural relics, and was only released at the beginning of this year.

Then such a person must become the object of suspicion in our focus.

Lao Lu looked at Zhang Zhaochai's photo and said: "This guy looks like a monkey with a sharp mouth, I don't think it's far from ten." ”

I said, "Catch the thief and catch the stolen goods, catch the traitor and catch the double." This Zhaochai is indeed a huge suspect, but we still have to get evidence of his tomb robbery. And there is a key question, where is this Zhang Zhaochai now? Will it be because he has fled Wanzhou after committing the crime. ”

Lao Lu nodded and said, "How do you think we are going to get evidence of his crime now?" And how to find his traces? ”

I didn't feel disgusted by Lao Lu's question, and I wouldn't say why he didn't use his own brain to think about it, because I was his advisor.

I said, "I think we should first find the light truck that was used to rob the grave." In the two days of the incident, we can call up the monitoring along the 318 National Highway, if the same light truck appeared on these two rainy nights, then this kind of car is very likely to be the vehicle that committed the crime. As long as the vehicle that committed the crime is found, then the evidence of the crime will definitely be found on the vehicle. At the same time, it can also pull out the suspect through the owner of the vehicle. ”

Lao Lu nodded and said, "Okay, just do it, and put the focus of the investigation on this suspect vehicle." ”

Lao Lu stood up and was about to walk out of his office to arrange the work, I hurriedly said, "Don't worry, I still have a guess." ”

Lao Lu stood in front of his desk and said, "What speculation? ”

I said, "Is this tomb robber gang organizing such a large amount of manpower and material resources just to steal this ancient tomb?" ”

Lao Lu said: "You mean that these people will have the next move?" ”

I said, "Quite possibly." And the scope of their crimes, I think, will not only be in Wanzhou District, but will definitely extend to other districts and counties. And the target of their crime is also a remote ancient tomb. I even think that the ancestral tomb of the Xue family is not the place where they committed the crime for the first time, and there may have been many ancient tombs that have been excavated. It's just that the perpetrator is sophisticated and uses heavy rain as a cover, even if he finds that his ancient tomb has collapsed, he thinks it is because of the heavy rain, so he doesn't think that it is a tomb robber and calls the police. Or those ancient tombs that are left unattended and whose descendants will only go to hang incense on paper at the end of the year, even if they have been stolen and excavated, but no one has found them, and no one has called the police. ”

After hearing this, Lao Lu clapped his hands and said, "What you said is very reasonable. I understand what you mean, we should do a survey of the surrounding tombs, identify those tombs that have not been stolen and excavated, but have the value of theft, and then control them, and wait for the rabbits. ”

I said, "That's right." Not only do we have to wait for the rabbits, but we also have to take the initiative to attack and take a two-pronged approach in order to catch this group of tomb robbers as quickly as possible. ”

After that, Lao Lu instructed the investigators to thoroughly and secretly explore the ancestral tombs of the ancient tombs in the area and surrounding districts and counties, and secretly cooperated with the local police to control these ancient tombs.

Lao Lu and I carried out a monitoring investigation on the two nights when the ancestral tomb of the Xue family was destroyed. Sure enough, a white light truck was found, which appeared on National Highway 318 for two nights, and the position where the car appeared did not exceed the machine plow road of the forest farm. And both times it appeared in the same surveillance, and three hours later, it returned to the city from this surveillance. Then I guess that these three hours are the time for them to commit crimes.

In the surveillance in the city, we found the high-definition picture of this light truck and determined the license plate number. And it can be clearly seen that sitting in the co-pilot is the criminal suspect Zhang Zhaochai.

Unfortunately, after investigating the license plate, it was found that the license plate of this light truck was actually a deck. The investigation from the vehicle was interrupted.

Lao Lu is a persevering person, he carefully observed the light truck under the high-definition probe, his purpose is to find out the characteristics of this light truck, and then through these characteristics, find out the corresponding vehicle.

This method of detection is effective, but it is more time-consuming and labor-intensive.

At the same time, Lao Lu also retrieved the recent hotel check-in information in the whole district, hoping to find the suspect Zhang Zhaochai in this information.

Lao Lu's wide-casting method of detection is obviously effective, but whether or not the suspect can be found through these methods will take time and luck.

Of course, those who can take the initiative to attack, Lao Lu did not fall behind at all. The rest is to wait for the rabbits, I wonder if this group of cunning tomb robbers will be guarded by us?

I made a suggestion to Lao Lu, and I said, "Keeping it all the time will not only make the brothers tired, but also easy to startle the snake." In my opinion, this group of tomb robbers has a characteristic of committing crimes, that is, they commit crimes on rainy nights. Then we can squat on a rainy night according to this situation, and I think it will be more likely to catch them. ”

Lao Lu agreed to my suggestion.

A week later, we waited for a rain. And within a week, the proactive investigation never stopped, but with little success. We pinned our hopes on this squatting.

There are a total of 11 locations to squat this time, and to be honest, it is the first time that such an extensive squatting is the first time, and I seem a little inexplicably excited and nervous.

In the second half of the night, the rain became heavier and heavier, accompanied by the rumbling thunder, and it seemed as if the sky was about to fall.

I whispered to Lao Lu: "This weather is a good time for tomb robbers. ”

Lao Lu also said in a low voice: "It seems that you are full of confidence in this operation!" To be honest, I've been a police officer for decades, and I've never had much hope for this kind of thing. ”

I smiled and said, "The greater the hope, the greater the disappointment." There is no hope, but there will be surprises. Comrade Lao Lu, I need to learn more from your mentality. ”

Lao Lu snorted and was about to speak, when his mobile phone suddenly rang.

"Team Lu, we have caught the suspect!"

Police cars sped through the rain, their lights flashed, and their sirens cut through the noise of the rainy night.

The criminal policemen squatting in Wuling Town stopped a white light truck at 2:37 a.m. A total of eight people were crammed into the passenger and back seat of the truck, and five people were also hidden in the cargo box of the truck. Among these thirteen people, the major suspect Zhang Zhaochai is among them.

Tools such as hoes, shovels, shovels, ropes and sticks were also found in the cargo box of the light truck. Although these tools do not have professional tomb robbery tools such as Luoyang shovels, they are more than enough for only stealing stone tablets outside the cemetery.
