Police Detective

Bai Song began to envy the protagonists of those mystery novels.

In mystery novels, all you need to do is deduce the correct answer and then find a few unique pieces of evidence. The criminal will be terrified and gradually give up resistance during the confrontation and admit what he has done.

But the reality is true.

Yao Lei actually died like this, and the cause of death was directly stabbed to death by Yao Xin.

The problem is, judging from the current situation, Yao Xin is probably not guilty.

Two cars quickly arrived at the scene, and Yao Xin had already been taken away. On the one hand, body fluids had to be collected, and on the other hand, she had to be questioned.

However, Bai Song heard that Yao Xin was mentally disturbed and in a trance, and he was probably frightened. Looking at this situation, he could not inquire about it for the time being.

This was the first time Bai Song saw Yao Lei, but he had already fallen into a pool of blood.

"How is the situation at the scene?" Bai Song asked.

Detective Xiao Zhao saw Bai Song and said quickly: "Detective Bai, Yao Lei was stabbed four or five times. Looking at the places where he was stabbed, it was basically random, but there were two stabs in the stomach and lungs. Yao Xin After calling the police, the 110 platform also notified 120. When 120 came, Yao Lei was already dead."

"The cause of death was excessive bleeding?" Bai Song asked.

"That's right." Xiao Zhao said.

"Did the two of them drink or take drugs?" Bai Song asked.

"No, judging from the scene, the two of them did have sex. And Yao Xin's resistance was obvious."

"What kind of injury is Yao Xin?"

"Multiple soft tissue contusions."

"What's her condition?"

"I feel like I'm having a mental breakdown."

"Is Yao Xin bleeding?"

"Bleeding? Soft tissue abrasions, there must be some bleeding." Xiao Zhao asked doubtfully.

"I'm not talking about injuries and bleeding." Bai Song remained serious.

"Ah?" Xiao Zhao was confused and didn't understand what it meant.

An old forensic doctor next to him heard this and took Bai Song's words and said: "There is no bleeding."

"Well, thank you." Bai Song nodded, indicating that he was fine.

Xijing Branch, conference room.

"I agree with the plan deduced by Detective Bai." Detachment Liu said again: "But in the situation at the scene, not even a little bit of butene or butane could be collected, the bottles were all broken, and even the wine was dried. . Originally, there were some special substances in the wine, and there were traces even after it was dried. However, after the high-pressure water cannon was used to put out the fire, there were no traces that could be recovered."

"In this case," Zhuang detachment said: "Now, it can be basically believed that Yao Xin wanted to use Yao Lei as a scapegoat for killing Yao. Yao Lei also brought two bottles of wine, which was probably ordered by Yao Xin, and Yao Lei It is true that they tried to withdraw Yao’s money, and it was probably instigated by Yao Xin. Now, Yao is dead like this.”

This matter may really be hanging in the balance! Yao Lei and Yao Xin both brought two bottles of wine, and now this is where the trouble lies. And it's so cold now, and the clothes are thicker. From the surveillance camera, we can't see if there are any small items hidden in the clothes.

Having said this, detachment Zhuang looked at everyone: "This matter is already like this. Yao Xin must be under control. Yao Lei's autopsy probably has no valuable clues. Now everyone can speak freely and don't be afraid of making mistakes."

"The motive for the murder is probably very simple." Bai Song said directly: "Both Yao and Yao Lei are definitely not good people. Yao Lei did this to Yao Xin without drinking or taking medicine tonight. Even Yao Lei did this to Yao Xin. Xin used some means, which also means that this is not the first time. As for Yao Xin's silent character, he can deliberately murder Yao, and even plan for a long time. I think Yao must have had similar feelings towards Yao Xin. Behavior."

"I agree with this." Detachment Zhuang said, "This should be the motive for the crime."

Such tragedies are not uncommon, and many people are simply not worthy of being fathers.

If there had been such a history, it would be normal for Yao Xin to develop his current personality, and this murder had probably been planned for a long time. The good girl who has been a good girl for so many years has basically been submissive and acted out!

In fact, Bai Song had no doubt that Yao Xin told Yao that he invited people to drink the night before the incident. Although Yao is not very good at listening to Yao Xin, it is still easy for Yao Xin to use his affection and reason to let his father treat the workers to dinner and drinks on his birthday before the start of the new project.

The current situation is, where can we find the evidence?

"Is there any problem with the on-site determination of self-defense?" Detachment Liu asked this question.

"Director Wei will come over in a while, let the leader make a decision." Detachment Zhuang looked at his watch, it was 3:40 in the morning, and then said: "We are already on the way."

"good."

After a brief silence, Bai Song said: "There is still a lot of evidence that can be investigated. First of all, where did Yao Lei buy the wine? Now we can basically deduce what Yao Xin did. Yao Xin has been planning for so long, and there are many Precautions are probably taken for everything, but she can instigate Yao Lei, but she cannot completely decide what Yao Lei does. We can check the place where Yao Lei bought alcohol, and then follow up and monitor, maybe we can remove Yao Lei's suspicion. Except In addition, Yao Xin must have thought that fire can destroy everything, but there are still loopholes, such as styrofoam, and we need to find records of Yao Xin purchasing styrofoam."

"Styrofoam?" Detachment Liu asked in confusion: "Inspector Bai, what's going on?"

Bai Song then realized that this information had not been shared.

Detachment Liu obviously heard that this was important information, but Bai Song seemed very disrespectful if he said it now. Although Bai Song is the superior department, intelligence sharing should be done.

After thinking for a while, Bai Song narrated the discovery process, and then said: "I have some friends at the Criminal Division, and I asked them to do a test overnight. I just found out that it was styrofoam, used for sealing. The location where it was found was very Something is wrong. Of course, if the two windows were not tightly fitted together, they would have been damaged by the water even if they were not burned by the fire."

"Inspector Bai's men are indeed strong generals." Detachment Liu naturally knew that Bai Song forgot to tell them this, but Bai Song's explanation meant that he was stepping down, and he would definitely not pursue it. He has decades of work experience. This kind of thing is too normal, but he must have this authority in the conference room.

"It can be considered an accident." Bai Song said: "The glass of the two windows was broken, but the aluminum alloy is still relatively strong."

"Okay, we have to do our best to investigate this aspect, including the place where Yao Xin went without returning home the night before. It is estimated that this is where she fractionated butene and butane." Detachment Liu said: "In addition, Bai Detective, do you have anything to add?"

"Liquefied petroleum gas is not only sold at liquefied gas stations. Many portable hot pots also have small liquefied gas bottles. These are easy to buy. We need to conduct extensive investigations." Bai Song said.

Detachment Liu looked at Bai Song, nodded, and said nothing.

This kind of thing is so brain-burning. I was eating noodles for lunch today, and I was still analyzing how to write it.

Really losing my hair.

I guess after I finish writing this book, my hairline will move back a few centimeters without any problem.
