"Why is there no surveillance?" Wang Liang was sitting in the car, feeling a little depressed. After they checked, they found nothing.
"If all the surveillance cameras were there and the case was solved, we wouldn't be here," Ren Xu answered honestly.
"Well... that's right... most of the cases have complete surveillance, so they are easy to solve... We are all difficult to deal with." Wang Liang sighed: "They really choose the right people to let the two of us investigate the affairs of these two wedding companies, alas..."
"Captain Wang, I'm hungry..." Ren Xu felt a little embarrassed.
"Ah? You should have said it earlier. Let's go and eat first." Wang Liang immediately agreed.
"Let's eat hotpot," Ren Xu wiped his mouth.
When Wang Liang heard the word "hot pot", he subconsciously wanted to nod, but he looked at Ren Xu and said, "Let's have some noodles."
Fortunately, I have reacted quickly recently!
Wang Liang found that he was in a really good state recently. When Bai Song asked him to shut up, he didn't say much, thus avoiding being beaten. He was also quick-witted when looking for the car just now, and now because of his quick reaction, he saved at least more than a thousand yuan!
"A little noodles," Ren Xu nodded and wiped his mouth.
"Plenty of pork intestines, beef, and beef tendons." Wang Liang still felt a little embarrassed. When he was abroad a few days ago, Ren Xu paid for the food several times. It would be a bit unkind for him to just treat him to a bowl of noodles.
"Okay!" Ren Xu's eyes lit up.
The two weddings of Lin Liang have now been investigated. There is nothing wrong with the person who recommended the wedding to Lin Liang. This person is one of Lin Liang's friends, and was one of the buddies who went to the bath center with Lin Liang on the day he died.
This person definitely did not have the time to commit the crime, and the two people had a relatively good relationship. After careful investigation, there was indeed no motive for murder. He also had a mortgaged car for wedding business, and sometimes they helped each other.
At present, it is highly likely that the murderer who killed Lin Liang obtained Lin Liang's movements during the conversation with him, so it is not very meaningful to trace back the two families' marriages here. Bai Song still hopes that Wang Liang can retrieve more surveillance footage from that day and before the incident to see if he can find the car used by the suspect.
Logically speaking, the suspect must have used mechanical equipment when making preparations 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 noodle restaurant nearby where people were eating and took Ren Xu in.
"Boss, two big bowls of noodles! Both with pork intestines, beef and beef tendons!" Wang Liang found a table and sat down.
"We have two kinds of servings here, 2 liang and 3 liang. Do you want two bowls of 3 liang?" the boss came over and asked.
"3 taels?" Wang Liang looked up at the tables around him and asked, "How much are they?"
"That one is 3 Liangmian," said the boss.
"Oh, then give me half a catty and give him one catty." Wang Liang nodded: "Add more meat, how much should be paid."
"Then you can order separately. One bowl should be no more than 100 grams of noodles, and 100 grams is already a lot." The boss saw that the two were from the north, "Don't worry, it's enough."
"Okay then, let's start with three bowls of 4 liang." Wang Liang said.
"Is there anyone else who hasn't arrived yet?" The boss looked outside the door.
"Go ahead," Wang Liang nodded, "and pay the bill last."
"Do you want cilantro?"
"no problem."
It was not meal time, so there were not many people in the noodle shop. The boss quickly brought up three bowls of noodles.
All three bowls of noodles were full, with red oil floating on top. Each bowl was topped with large chunks of beef, tendons, and pork intestines, emitting a hot and fragrant aroma that made people's appetites grow.
Wang Liang picked up a piece of beef tendon, blew on it, bit off most of it in one bite, then sucked the air and began to chew the whole thing.
Phew… a little spicy… Wang Liang waved to the boss: “Give me four bottles of mineral water, room temperature.”
After taking a sip of water, Wang Liang continued to eat the noodles. He found that although the noodles were delicious, they were too spicy...
"No, no, I can't eat this." Wang Liang picked up the little bit of noodles he had taken a bite of and pushed it to Ren Xu: "I ate a piece of meat and a mouthful of noodles. If you don't mind, you can eat this bowl too."
"Okay, put it there and order another bowl," Ren Xu nodded and wiped the sweat from his head.
"Boss, another bowl, but not spicy at all." Wang Liang said, "Four ounces."
"The noodles don't have to be spicy, but the topping itself is spicy, there's no way to make it not spicy at all," said the boss.
"It's okay if the topping is spicy," Wang Liang said, "Put less topping..."
While waiting for the noodles, Wang Liang saw that Ren Xu was almost finishing his bowl.
In Bai Song's words, Ren Xu is not "able to eat spicy food" but "able to eat anything", so this small noodle with standard spiciness is no problem at all.
However, Ren Xu was sweating while eating, and he had already drunk half a 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 so greedy that he wanted to pick another piece of beef, but he had already given it to the waiter, so it was inappropriate to pick up his chopsticks. While he was anxiously waiting, three minutes later, the boss came over with the second bowl of noodles.
"Can't you eat spicy food?" The boss saw that Wang Liang had finished the bowl of food in front of him.
"He eats it." Wang Liang pointed at Ren Xu and said, "Boss, please take this bowl away."
"Is this the second bowl?" The boss pointed at Ren Xu's bowl with a look of disbelief, placed the bowl of noodles in his hand in front of Wang Liang, took away the bowl with only soup left, and looked here frequently as he walked away.
The boss has been in this business for so long that he has seen people eating two bowls of 3 liang rice, but he would never believe someone eating three bowls of 4 liang rice. After putting the empty bowl back, he kept staring at it, wanting to see if the person could finish it.
"Hey, you said, the one who killed Lin Liang," Wang Liang looked around and saw that there was no one around, then whispered, "What equipment did he use? You see, logically, this person didn't have long to prepare. After all, it wasn't long before Lin Liang heard about these two jobs from his friends, so it's impossible that the equipment was prepared a long time ago. So what equipment did he use? We checked the video footage of the past few days, and every engineering vehicle that passed by didn't stop on that road."
"I don't know," Ren Xu chewed his meat and wiped his sweat, "Didn't Team Bai say that they needed large equipment?"
"How big is considered large..." Wang Liang said, "I feel like if it's a large device, it must be the kind that can be driven up the mountain, right? For example, an excavator? But the traces are too obvious, could it be a single-person device?"
"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's equipment?"
"It should be okay, right?" Wang Liang was a little uncertain and took a bite of noodles. "I feel that technology is getting more and more advanced now, and many gasoline engine equipment are also very powerful."
Ren Xu wiped the sweat off his face again and reached out for some water: "Captain Wang, there's not enough water..."
"Boss, two more bottles," Wang Liang waved his hand.
"Right away!" The boss was paying attention to this table. He was already impressed. He wanted to take a photo but felt it was inappropriate. When he heard that they wanted water, he immediately brought over two bottles of room temperature water: "Drink more water with this. Drink enough water and don't overeat."
"Thank you, boss." Ren Xu took it and drank half of the bottle: "This..."
Wang Liang suddenly interrupted Ren Xu at this time: "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 occurred in that place was because it was filled with water! These devices may be for one person, but the water is at least several tons! This cannot be handled by a small car."
"Captain Wang is awesome!" Ren Xu's eyes widened. "You make sense. Let's check the water trucks."
"It's not just the water truck." Wang Liang has many years of experience in checking surveillance cameras, and he also knows how suspects will avoid surveillance: "It could be other vehicles in disguise. For example, if the back of a van is dismantled and a water tank is placed on it, it can also hold a ton of water. But this will cause the van to stay in that area for a longer time! You see, there is no surveillance at the crime scene, but there are on the roads at both ends. The two surveillance cameras are four kilometers apart. I can build a model!"
Wang Liang plans to build a model in which different types of vehicles have an average passing time during different congestion periods. If a transport truck, lorry, van, etc. stays for a long time longer than the average, they will automatically stand out from the software modeling and become abnormal data.
If the murderer is the co-pilot, it would not take too long to stop if he is carrying a small piece of machinery alone, so this solution would not work. But if several tons of water are needed, and the water needs to be pumped to a hillside several dozen meters high, it is definitely not something that can be done in three to five minutes.
"I feel it was most likely done at night when there are fewer people around. It would be too conspicuous to park a truck here during the day," Ren Xu added.
"Yes, that's for sure," Wang Liang nodded immediately, "Eat quickly, and then get back to work."
Wang Liang stood up and paid the bill to the boss. The two of them spent more than 100 yuan.
After paying the bill, Ren Xu also finished eating, and the two quickly left the noodle shop. The boss came over to check and was amazed at how clean the food was...
While the two of them were checking the surveillance footage, Bai Song and the others went to the place where the construction waste was dumped.
It is very expensive to throw away garbage now, especially construction waste, which can easily be several thousand tons or tens of thousands of tons, and it is a huge expense. At that time, these were mainly soil, without harmful substances, but they could not be thrown away anywhere. At that time, the muck trucks also piled them here to save trouble.
"Dig it all up," Pang Hongshan directed the excavator, "Put it over here."
Things were going on in full swing here. Bai Song and a few others were watching from the side. A bunch of policemen were watching the excavator digging the soil with great interest.
"The soil itself doesn't speak much," Pang Hongshan said, "only the soil quality, soil layers, 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 the firefighters dug it up, so there must be nothing to see."
"It's OK if you understand this," Pang Hongshan said. "Although I'm a geologist, I don't know how much hope this gives you. Although they have been working hard to find this soil, it doesn't make much sense to look at it now. Moreover, it has been buried for several days, and the moisture level of the soil has completely changed."
"Yeah," Bai Song nodded, "Just check if there is any other evidence in the soil."
There was only one excavator on Baisong's side. After more than an hour, they dug out hundreds of cubic meters of soil. A group of people dug for a long time but found nothing.
"I don't think this will work. We have to fill it back in," Bai Song said to the team leader.
"Then this road has been blocked," said Dai, with an unhappy look on his face. He really hoped to find something because his previous judgment was wrong. Now that he had found new clues, he couldn't wait to prove something.
"It's okay," Bai Song said, "We still have many ways to go."
"Yes, yes, yes," the team leader felt a little bitter in his heart, because these so-called several roads did not lead to a solution from their side.
While they were chatting, Bai Song's cell phone rang. It was Wang Liang.
"What's the matter? There's an excavator working here and it's very noisy." Bai Song asked.
"Then find a quiet place. I have some important information here." Wang Liang said.
"Good!" Bai Song was a little surprised. Is Wang Liang so productive now?
After finding a quiet place, Bai Song listened carefully to what Wang Liang said, and then got the clue that Wang Liang mentioned.
During these few days, a total of 17 vehicles stopped between the two cameras for an abnormally long time, which was not normal at all. Of these 17 vehicles, 13 were small cars. After a simple investigation, they were probably unrelated to the incident. They might have stopped by the roadside to use the toilet or make a phone call in the car... Another one might have had sex outdoors, because Wang Liang saw the female passenger in the front passenger seat was disheveled at the second camera...
There were four vehicles with cargo capacity, one semi-trailer, and the cargo area was clear at a glance, so they were ruled out. The remaining vehicles were a large van and two vans, and all of them stopped here at night, so they were all relatively suspicious.
Being able to pinpoint this point, the case has basically been solved. Bai Song immediately said, "Okay, I understand. You guys go take a rest. Later, you two can go have a hot pot meal and bring the invoice to me for reimbursement. I'll treat you. You don't have to do anything here. I'll be in charge of the investigation."
"I just finished eating," said Wang Liang.
"I'm tired after checking for so long..." Bai Song said, "It doesn't matter if you've finished eating. Take Ren Xu with you. He will definitely be able to eat something."
After hanging up the phone with Wang Liang, Bai Song took a deep breath.
The most difficult part of this case is the death of Lin Liang. This case involves a relatively large scope and there is very little evidence. But now that we have found very direct evidence such as the license plate number, it can be said that solving the case is within reach!
Is Wang Liang's logic so meticulous now? Bai Song even feels it's unreal.
