The next day, Bai Song still felt a little sleepy when he got up. The three hours last night were more tiring than doing the test questions. The amount of data and evidence in his mind was too much. Bai Song ate such a big bowl of noodles last night, with pork intestines and beef, but he was actually hungry when he went to bed. It was obvious that he had consumed a lot of energy.
It was right to ask an expert for this case. Logically speaking, white pine is actually of little use.
There are two difficulties in handling the case now. The first is the geological problem, and the second is the trace problem at the scene of Lin Qing’s murder. The people we invited, such as Mr. Pang and Ouyang Xinyu, are both very targeted.
However, Bai Song is familiar with the process here. This should be the case situation raised by the local authorities, and Director Wei and others held a meeting to study and arrange personnel.
Therefore, 80% of the personnel arrangement is reasonable. The only unreasonable thing is why Bai Song was sent here...
Isn't this redundant...
Thinking of this, Inspector Bai felt somewhat sad...
After getting up, he first paid attention to the group.
Wang Liang and his friends have been having a great time these days. Simply put, they have three small barbecue meals a day. The food there is not very good, but there are a lot of barbecues. They are now going through the formalities and should be back in two or three days.
If all his team members were here, Bai Song was confident that he could thoroughly understand the entire case today and then start analyzing the things needed to handle the case, but at the moment he was alone and had no help.
I didn't have much contact with Pang Laobaisong before, I only knew that he was an old scholar, but I think he has real skills. Ouyang Xinyubaisong has met him twice, this person is really amazing, in the field of trace detection, Hao Zhenyu was not as good as her. You know, Hao Zhenyu is Wang Huadong's mentor.
It was time for dinner. After washing up, Bai Song was starving and still felt a little uncomfortable when he went out.
I looked in the corridor and saw that the male policeman who was here last night was still sitting there. When he saw the Baisong door open, he immediately stood up and walked over.
"Director Bai," the young policeman said, "Are you going to have dinner? Fourth floor."
"Okay, thank you," Bai Song asked, "Aren't you going to eat?"
"I'll have someone to take over my post in a moment. There are confidential materials in your room, so no one can leave. Go eat first, and don't worry about me."
"Okay, thank you for your hard work." Bai Song nodded: "What's your name?"
Bai Song could tell from the policeman's appearance that he definitely did not sleep that night and just sat there all night.
When the young male police officer heard this, he immediately stood at attention and replied, "Leader, my name is Zhang Yixin!"
"Okay," Bai Song nodded and decided to praise this policeman to local leaders when he had time today.
…
The breakfast on the fourth floor is ok, it is the hotel's buffet. Because the level here is good and the breakfast standard is not low, we did not arrange any extra breakfast.
After eating for more than ten minutes, Ouyang Xinyu and Yu Yali also came over and greeted Bai Song.
Yu Yali told Bai Song that Pang Hongshan had finished his meal and was waiting for everyone on the first floor. The older people got up early.
"I can't digest the sushi in the room last night," Ouyang Xinyu said, "Eat less and I'll go down."
"I'm almost done eating too," Bai Song said, "You guys should eat a little, after all, we're probably going to be very busy in the morning."
After saying that, Bai Song started eating with big mouthfuls.
The two experts had very little material to look at last night as they needed to go to the scene more, so they slept better.
After breakfast, the four of them followed the car and went to the Beiyu Branch together.
At Bai Song's suggestion, everything was kept simple and the case report began directly at the welcoming meeting.
The person who made the report was the acting captain here. He was capable and sorted out the case from beginning to end.
According to current reasoning on the case, it is generally believed that Lin Liang is the murderer of Lin Qing, not only because of money, but also because of the emotional entanglement between the two.
Lin Liang must have had an accomplice in the murder, otherwise it would not have been possible for someone to use Lin Qing's cell phone number to send WeChat messages to Lin Qing's mother three days after Lin Liang's death.
According to the deputy detachment, the person who told Lin Qing's mother the situation might not have done so to anger the police or show off his skills, but might have felt guilty and found a suitable reason to let Lin Qing's mother discover that her daughter was dead.
If we analyze it this way, the reason why this person did not call the police and did not explain the situation to Lin Qing's mother was probably to avoid investigation. This person was worried that if he called the police directly or told Lin Qing's mother that her daughter was dead, Lin Qing's phone, which he was using, would be reversely located, threatening his own safety. In fact, Lin Qing's phone was indeed turned off after sending the message to Lin Qing's mother, and the location was completely lost.
Bai Song agreed with the analysis of the deputy detachment. Most suspects would evade investigation, so it was normal for them to take such extreme measures. The murderer felt guilty and wanted to tell Lin Qing's mother about her death. This phenomenon was also reflected in some related cases.
Mobile phones used by young people all have passwords. Most people naturally wouldn’t know Lin Qing’s password, except for Lin Liang, because they used to be a couple. This also indirectly proves that the person who sent the message is with Lin Liang.
Analyzing from here, this person not only knows both of them, but also has a grudge against both of them. This is really not normal.
Let’s talk about Lin Qing first. Although Lin Qing offended some colleagues for unknown reasons, all the current evidence shows that the people Lin Qing offended were just minor troublemakers, and there was no need to kill her or dismember her.
As for Lin Liang... there are many people who want to kill Lin Liang, including the workers and partners he has cheated, few of whom don't want to kill him.
Therefore, the current deduction of the deputy detachment is that the other person actually has a big grudge against Lin Liang, but Lin Liang himself thinks that the relationship is still good. Both of them are short of money. When Lin Liang killed Lin Qing, this person may be a helper or a bystander.
Later, the two separated, and this man found a way to kill Lin Liang.
Bai Song could only half agree with the deduction of the deputy detachment. First of all, Bai Song assumed that the person who killed Lin Liang was a master. Why would such a person kill Lin Qing together with Lin Liang? He would not do such a thing for a little money, right?
The money in Lin Qing's card is still there and no one has taken it away. There are only a few thousand yuan and some electronic equipment in the house, which adds up to only about 30,000 to 40,000 yuan. This is really not worth it for a capable person.
After hearing this, Bai Song did not continue speaking and continued to listen to what Dai Zhita said.
"Lin Qing's mother has a very serious problem. She has developed a prolonged psychogenic disorder, or PTSD, which is a serious stress-related mental illness. She is now completely unable to cooperate with our questioning," said the deputy detachment. "It has been Lin Qing's father who has been cooperating with us."
"Is it so serious?" Bai Song was a little puzzled.
It is indeed difficult for people to empathize with each other, and it is impossible to share the same joys and sorrows. Bai Song could understand that Lin Qing's mother was extremely devastated and even in a trance when she found her daughter's body, but he still couldn't expect her to be so frightened.
The deputy detachment was relatively accurate in describing the case, stating the reasoning as reasoning and the speculation as speculation. Since Lin Qing's mother was diagnosed with PTSD, there should be no problem, and Bai Song did not need to confirm it.
"Very serious," the deputy team took out a video and showed it to Bai Song. Bai Song took a quick look and knew that Lin Qing's mother was indeed "crazy", which was not something that could be pretended.
"Do you understand where Lin Liang was going and what he was going to do when he drove out that day?" Bai Song began to ask key questions.
"From what we know so far, he should be sending the car to Beichuan District. There are two weddings going on there, and he will be there for two days to run the wedding car business," Dai said. "There are records of this."
"After killing someone, he still wants to drive a wedding car?" Bai Song frowned. "He has a good mental quality. This means that this person doesn't just make money by cheating others. He also makes this kind of money."
"It's a Porsche after all," Dai said, "He has received the deposit, but it's only 200 yuan. He has to go and drive to get the balance."
"Then do you know his previous whereabouts?" Bai Song asked back.
"Really not," said the deputy detachment. "There are too many people or things to investigate in this case. Regarding what you mentioned, we arranged for someone to investigate several days ago. There was some progress this morning. I will definitely report to you when the results are out."
"Okay, I've almost understood the case," Bai Song said. "I looked through their relationship chart last night, but it's a bit messy. I don't think you're responsible for this. Let the special police come to me and explain it to me more clearly. Now let's quickly arrange for two experts to guide the case. I think they also understand the basic facts of the case."
"Okay, since these are two different scenes, I have arranged two cars. Which one will you go to, Director Bai?"
"I'll go to Lin Liang's place and follow Mr. Pang," Bai Song said to Yu Yali, "You do the service work over there."
"I understand," Yu Yali nodded immediately.
After everything was packed up, we were ready to set off. At this time, the deputy detachment received a call. After listening to a few words, a look of confusion appeared on his face.
"What's the matter?" Bai Song stopped and felt that there was a new clue.
"This news has not been confirmed yet," said Dai. "My investigators told me that they found a few of Lin Liang's friends. Lin Liang played with them on the day of his death and the afternoon before. He went to a bath center and never left them for more than an hour. The bath center is at least half an hour's drive from Lin Qing's home. There is enough time to make a trip, but according to our previous estimate, it would take at least four hours for the murderer to kill Lin Qing, cut her up, and then carefully clean her."
"Please ask the detachment to confirm this matter in person." Bai Song also had some doubts on his face: "If this is the case, Lin Liang can be exempted from the suspicion of murder that day."
"I will definitely investigate it carefully." It's not that Dai Zhita didn't trust his subordinates. This matter was too important and he would feel uneasy if he didn't ask about it himself.
Bai Song was relatively confident in the Dai detachment, so he did not go with them. He stopped thinking about the matter and took Pang Hongshan to the scene of the accident.
It's a sunny day today and the morning rush hour has passed, so there aren't many cars when we arrive at the crime scene.
The road here is not wide, it is a two-way two-lane road, so it is not convenient to park the police car on the side of the road, so other cars can only go the other way if they want to pass. Although the police car has privileges, Bai Song still suggested that the car be parked near a platform more than 200 meters away from the crime scene, and everyone walked over.
There were seven or eight people in the group, and some were taking photos along - this would be on the police station's website for news.
Pang Hongshan was holding a blue Estwing geological hammer, which didn't match his plain look, and walked in front.
If Bai Song walked in front of him, it would be very troublesome, so letting Pang Lao walk first did not mean being disrespectful to him.
When he arrived at the scene, Pang Hongshan squatted down and searched for something on the roadside bit by bit.
Although many days had passed and it had rained, there was still mud and stones that had fallen from the mountains on the roadside.
After simply picking up some, Pang Hongshan knocked again, then pointed to the mountain where a small piece was missing: "I want to go over and take a look."
Naturally, no one would refuse. The two young policemen were familiar with the place and led everyone up the hill.
There was no one here who could help, so Pang Hongshan wandered around here alone for more than half an hour.
"Bai Ke, come here," Pang Hongshan waved his hand, and Bai Song ran over in a few steps.
"Don't run, be careful the soil might slip again," Pang Hongshan stopped him.
"I understand," Bai Song walked over step by step.
"The main cause of the landslide is not the terrain, but the nature and distribution of the stratum soil. Of course, rainfall, earthquake and vegetation are the main causes. The preventive excavation carried out here later caused great damage to the site, but it can still be seen that this is a layered landslide, that is, the rock layer tends to have the same slope direction as the slope, and the rock inclination is smaller than the slope inclination to form a landslide. From a geological point of view, there is a major hidden danger of naturally formed landslides here." Pang Hongshan said.
"So?" Bai Song asked, "Mr. Pang, what do you mean?"
"This is an uphill corner where cars usually drive at low speeds. The road is narrow and in poor condition, so cars tend to gather here. Convex mirrors are installed on the curves here, but they don't work well on rainy days, so car speeds will drop further," Pang Shan said. "All I can say is that this corner is the most prone to landslides, not here."
"Is there a possibility of man-made explosion here?" Bai Song asked.
"If you want to make hundreds of tons of sand and gravel fall down so quickly, the explosion will make a loud noise," Pang Hongshan said. "Other mechanical methods are relatively slow and cannot be hidden."
"Then..." Bai Song was confused. The statements of other drivers at the scene were taken. The landslide happened in an instant, and there was no explosion. If there was, it would be so obvious that everyone would have heard it. "Is it possible that the landslide had already occurred in advance and was only blocked by a barrier net?"
Pang Hongshan was stunned for a moment after hearing Bai Song's words. He knew a lot about geology, but he was not as good as Bai Song in designing and reversing the crime methods. After hearing Bai Song's words, he thought for a while and said, "I'll take a closer look."
