Police Detective

"Why is there always no surveillance?" Wang Liang was sitting in the car, feeling a little depressed. After checking, they found nothing.

"If the surveillance was complete and the case was solved, we wouldn't be here." Ren Xu answered honestly.

"Well, the monitoring of most cases is relatively complete, which means that it is difficult for us to crack it." Wang Liang sighed: "Let the two of us investigate the wedding affairs of these two families, we are really good at choosing people, ugh."

"Captain Wang, I'm hungry." Ren Xu was a little embarrassed.

"Ah? You told me earlier, let's go and eat first." Wang Liang immediately expressed his approval.

"Let's eat hot pot," Ren Xu wiped his mouth.

When Wang Liang heard the word "hot pot", he subconsciously wanted to nod, but he glanced at Ren Xu: "Go and eat some noodles."

Fortunately, I have responded faster recently!

Wang Liang found that he was in really good shape recently. When Bai Song asked him to shut up, he stopped talking and avoided being beaten. He was thinking quickly when he was looking for the car, but now he has saved at least a thousand dollars because of his quick reaction. !

"Small noodles," Ren Xu nodded and wiped his mouth again.

"The fat intestines, beef, and beef tendons are enough." Wang Liang was still a little embarrassed. When he was abroad a few days ago, Ren Xu spent several times to buy food. It would be unreasonable for him to just treat him to noodles.

"Okay!" Ren Xu's eyes lit up.

The matter of Lin Liang's two weddings has now been found out. There was nothing wrong with the person who recommended the wedding to Lin Liang. This person was one of Lin Liang's best friends, and he was one of the buddies who went to the bathing center to play with Lin Liang on the day of his death.

This person definitely had no time to commit the crime, and the relationship between the two was relatively good. After careful investigation, it was found that there was indeed no motive for the murder. He also had a mortgaged car to attend weddings, and sometimes they helped each other.

At present, there is a high probability that Lin Liang's murderer obtained Lin Liang's movement track while chatting with Lin Liang, so it is not very meaningful to come here to check the marriages of these two families. Bai Song still hopes that Wang Liang can collect more information. Surveillance that day and surveillance before the crime to see if the car used by the suspect could be found.

Logically speaking, the suspect must have used mechanical equipment when preparing in advance, so it is possible to find clues by paying attention to the cars that passed by here before.

But Wang Liang was already very tired, so he found a nearby noodle restaurant where people were eating, and went in with Ren Xu.

"Boss, two big bowls of noodles! Both with sausage, beef, and beef tendon!" Wang Liang found a table and sat down.

"We have two bowls of 2 taels and 3 taels here. Do you have two bowls of 3 taels?" the boss came over and asked.

"Three taels?" Wang Liang raised his head and looked at the tables around him: "How much do they cost?"

"That one is Sanliangmian," the boss said.

"Oh oh oh, then give me half a catty and give him 1 catty." Wang Liang nodded: "Add more meat, how much does it cost."

"Then please separate it. A bowl can have up to four taels of noodles, and four taels is already a lot." The boss saw that these two people were from the north, "Don't worry, there is enough to eat."

"Okay, let's have three bowls and four taels first," Wang Liang said.

"Is there anyone else who hasn't come?" The boss looked outside the door.

"Go first." Wang Liang nodded and said, "Finally, we'll settle the bill."

"Do you want cilantro?"

"no problem."

It was not a meal at the moment, and there were not many people in the noodle shop, so the boss quickly brought out three bowls of noodles.

The three bowls of noodles are very full, with red oil floating on them. Each bowl is topped with large pieces of beef, beef tendon, and fatty intestines, and the steaming aroma makes people's fingers lick their fingers.

Wang Liang picked up a piece of beef tendon, blew on it, bit off most of it, then sucked in the air and started chewing the whole thing.

Phew. It's a bit spicy. Wang Liang waved to the boss: "Bring me four bottles of mineral water, at room temperature."

After taking a sip of water, Wang Liang continued to eat noodles. He found that although the noodles were delicious, they were too spicy.

"No, no, I can't eat this." Wang Liang picked out the bit of noodles he had eaten and pushed it to Ren Xu: "In addition to eating a piece of meat, I only had a bite of noodles. If you don't mind, You should eat this bowl too.”

"Okay, leave it there and order another bowl." Ren Xu nodded and wiped the sweat from his head.

"Boss, here's another bowl. It's not spicy at all." Wang Liang said, "That's four taels."

"The noodles don't have to be spicy, the toppings themselves are spicy, there's no way it won't be spicy at all," the boss said.

"Just make the toppings spicy," Wang Liang said, "put less toppings."

While waiting for the noodles, Wang Liang saw that Ren Xu had almost finished a bowl.

In Bai Song's words, Ren Xu doesn't "can eat spicy food", but "can eat anything", so the standard spicy noodles are no problem.

However, Ren Xu was sweating while eating, and now he had drank more than half of the bottle of mineral water.

"Don't worry." Wang Liang handed over two tissues: "Wipe your sweat."

"It's okay, it's okay." Ren Xu thanked, "This tastes really good."

Wang Liang was greedy looking at it and wanted to pick another piece of beef to eat, but he agreed to give it to someone else and it was not appropriate to use chopsticks anymore. While he waited anxiously, three minutes later, the boss came over with a second bowl of noodles.

"Can't you eat spicy food?" The boss saw that Wang Liang had finished the bowl in front of him.

"He ate it." Wang Liang pointed at Ren Xu: "Boss, please remove this bowl."

"Is this the second bowl?" The boss pointed to Ren Xu's bowl with a look of disbelief. He placed the bowl of noodles in front of Wang Liang, cleared away the bowl with only the soup left, and looked here frequently as he walked.

The boss has been in this industry for so long that he has seen people eating two bowls of 3 taels, but he would never believe it if he ate three bowls of 4 taels. After putting the empty bowl back, he kept staring here, wanting to see See if you can finish it.

"Hey, you said, the one who killed Lin Liang." Wang Liang looked around and saw that there was no one a few meters away, and then whispered: "What kind of equipment did he use? Look, it stands to reason that this person didn't take long to prepare. After all, Lin Liang heard from his friends that these two people didn't live very long, so it couldn't be the equipment prepared a long time ago. So what kind of equipment should be used? We checked the videos of the past few days. Not a single passing construction vehicle stopped on that stretch of road.”

"I don't know." Ren Xu chewed the meat and wiped his sweat: "Didn't Team White say they need large equipment?"

"How large is considered large?" Wang Liang said: "I feel that if the equipment is large, it must be driven up the mountain, right? For example, an excavator? But the traces are too obvious. Could it be the kind of single-person equipment?"

"Single-person equipment?" Ren Xu took a sip of water: "It's possible. I don't know much about engineering equipment, but can this thing be done with only one-person equipment?"

"It should be fine, right?" Wang Liang was a little unsure and ate his noodles: "I feel that technology is getting stronger and stronger now, and many gasoline engine equipment are also very powerful."

Ren Xu wiped his sweat again and wanted to reach for water: "Captain Wang, there is not enough water."

"Boss, two more bottles," Wang Liang waved.

"Right away!" The boss was paying attention to this table. He was convinced. He wanted to take a photo but felt it was inappropriate. When he asked for water, he immediately brought over two bottles of room temperature water: "Eat this and drink more water. Water is required." Drink enough, don’t overeat.”

"Thank you, boss." Ren Xu took it and drank half the bottle: "This"

Wang Liang suddenly interrupted Ren Xu: "Hey, wait a minute."

"What's wrong?" Ren Xu didn't dare to move.

"We forgot a very critical issue," Wang Liang said: "The reason why the landslide in that place was because of the injection of water! These devices may be for one person, but the water must be at least several tons! This cannot be a small The car can handle it.”

"Team Wang is awesome!" Ren Xu's eyes widened. "What you said makes sense. Let's check the water truck."

"It's not just water trucks." Wang Liang has many years of experience in surveillance surveillance. He also knows how suspects will hide from surveillance: "It may be other vehicles disguised. For example, if the back of a van is disassembled and a water tank is placed, a tons of water. But this will cause the van to stay nearby for a longer time! You see, there is no surveillance at the scene of the crime, but there is a distance between the two surveillance cameras. I can model it!

Wang Liang plans to model. Different types of vehicles have an average passing time during different congestion periods. If there are transport vehicles, trucks, vans, etc. that stay far longer than the average, they will automatically be modeled from the software. Stand out as outlier data.

If the murderer is the co-pilot, carrying a small piece of machinery alone will not cause too much parking time, so this method did not work before. But if several tons of water are needed and equipment is required to pump the water to a hillside dozens of meters high, this is definitely not something that can be done in three to five minutes.

"I think it was most likely done at night when there were fewer people. Parking a truck here during the day would be too ostentatious," Ren Xu added.

"Well, that's for sure." Wang Liang nodded immediately: "Hurry up and eat, then go to work after eating."

Wang Liang got up and paid the bill to the boss. The two of them spent more than 100.

After paying the bill, Ren Xu also finished eating, and the two quickly left the noodle shop. The boss came over to check it out and was amazed that the food was really clean.

The two people here went to check the surveillance, and Bai Song and others went to the place where construction waste was piled.

Nowadays, it is very expensive to throw away garbage, especially construction waste. Thousands or tens of thousands of tons of construction waste can easily occur, which is a huge expense. At that time, these were mainly soil, with no harmful substances, but they could not be thrown away anywhere. At that time, the garbage trucks also piled them here to save trouble.

"Dig it all up," Pang Hongshan directed the excavator: "Dig it up and put it over here."

The work was going on here in full swing, Bai Song and a few people were watching, and a lot of police officers watched the excavator digging the soil with great interest.

"Soil itself doesn't speak much," Pang Hongshan said. "Only soil quality, soil layer, and soil structure can speak. For example, if the soil layers of the Qinyu Movement I mentioned are mixed together, nothing can be seen. "

"I understand," Bai Song said, "the soil has been mixed countless times, and it was dug by fire fighters in various ways, so there must be nothing visible."

"As long as you understand this," Pang Hongshan said: "Although I am engaged in geology, I don't know how much hope this thing gives you. Although they have been doing work to find this soil, but now it makes sense. It’s not big anymore. And it has been buried for several days, and the moisture level of the soil has completely changed.”

"Yeah", Bai Song nodded: "Let's see if there is any other evidence in the soil."

There was an excavator here at Baisong. It worked for more than an hour and dug out hundreds of square meters of soil. A group of people dug for a long time but found nothing.

"This probably won't work. You have to fill it in again," Bai Song told the Dai detachment.

"Then this road has been sealed." The acting detachment looked unhappy. He really hoped to find something, because his previous judgment was wrong. Now that he has found new clues, he can't wait to prove something.

"It's okay," Bai Song said, "We still have many ways to go."

"Yes, yes," the detachment on behalf of the detachment felt a little bitter. These so-called roads did not lead to them.

While they were chatting, Bai Song's cell phone rang. It was Wang Liang's.

"What's the matter? There's an excavator working here and it's very noisy." Bai Song asked.

"Then find a quieter place. I have more important information here." Wang Liang said.

"Okay!" Bai Song was a little surprised. Is Wang Liang so productive now?

After finding a quieter place, Bai Songzai listened carefully to what Wang Liang said, and then got the clues Wang Liang said.

In the past few days, a total of 17 vehicles parked between the two cameras for an unusually long time, which is not normal at all. Of these 17 vehicles, 13 are small cars. After a simple investigation, it seems that they have nothing to do with this matter. They may be parked on the roadside to use the toilet or make a phone call in the car. Another one may be engaged in field activities. Because Wang Liang saw the female passenger of the co-pilot was disheveled in the second camera.

There are 4 vehicles with cargo capacity and one semi-trailer. The cargo area is clearly visible and excluded. There was only one large van and two vans left, and they all stopped here at night, so they were all highly suspicious.

Being able to lock it in here, this case is basically a big button untied. Bai Song immediately said: "Okay, I understand, you can go and have a rest. Later, you two can have a hot pot meal and come to me with the invoice for reimbursement." , I invited you, you have nothing to do here, I will take charge of the investigation. "

"I just finished eating," Wang Liang said.

"I'm tired after checking for a long time," Bai Song said, "It doesn't matter if you finish eating. If you take Ren Xu, he will definitely still be able to eat some."

After hanging up the phone from Wang Liang, Bai Song took a deep breath.

The most difficult point in this case is the death of Lin Liang. This case involves a relatively large scope and there is very little evidence. But now that very direct evidence such as the license plate number has been found, it can be said that the case is already within easy reach!

This Wang Liang, is his logical thinking so rigorous now? The white pine trees all have an unreal feeling.
