Police Detective

Since you think there is a problem with this, you must open up your mind.

According to logical reasoning, this bottle must not have been drank directly, but was poured out and put into other bottles for the victim to drink by mistake.

Pesticide bottles are different from beverage and alcohol bottles, so pouring pesticide into other bottles may cause accidental drinking.

"Mixing pesticides into alcoholic beverages... Several common alcoholic drinks were found in the deceased's home. He did drink several bottles before his death, including beer. Find all these types of alcoholic beverages and mix them with pesticides to see how they taste." Bai Song analyzed road.

"I'll send someone right away," political commissar Wang said, and continued: "Although you can't swallow it, Team White, please don't try it...Do you still have a taste in your mouth? This is a distraction, I'll arrange for someone else to try it. , Don’t worry, you won’t swallow it.”

"Pay attention to safety." Bai Song agreed.

It was easy to find these wines. They were all very common local wines. After mixing them in different proportions, we finally came to the conclusion that unless there was only a little bit in a bottle of wine, the taste would be unpalatable.

Political Commissar Wang originally planned to arrange a few drinkers to experiment, but Bai Song stopped him.

People who drink too much have poor control. If they swallow it, it will be bad. Although it is not that serious to mix pesticides to reduce the concentration in small sips, it is too exaggerated to have several criminal police officers line up for gastric lavage during the Chinese New Year.

After doing this, everyone sat in the conference room and analyzed the case.

"So the logic still doesn't make sense. The deceased would not have drank by mistake." Sun Jie said.

Everyone knew what Sun Jie said, but the local criminal police didn't say anything.

"Could it be that the deceased had a cold and couldn't smell it?" Hua Dong came up with a new idea.

"It's mainly because my mouth can't stand it, not my nose. It smells nothing after mixing with white wine, but it still tastes bitter in the mouth." Bai Song still feels bitter in his mouth, and he spits out dozens of times with a tissue. .

While vomiting, Bai Song remembered the time when he was an undercover agent.

In order to sneak into the transportation company, Bai Song transformed into a bald man. At that time, Fu Bin, the character "played" by East China, had the habit of spitting, which was very annoying.

Because of this, Bai Song pays great attention to carefully wrapping paper every time he spits.

Slowly, Bai Song found that the taste in his mouth gradually disappeared, and finally returned to normal.

"Sun Jie," Bai Song suddenly interrupted. He didn't respond at all, so he called him by name directly: "What can make people lose their sense of taste?"

Sun Jie immediately understood what Bai Song meant.

What would happen if the deceased had no sense of taste during the period before death?

That drinking by mistake makes perfect sense.

"There are many things that can cause people to suddenly lose their sense of taste, but the most common one in life is probably disinfectant. Some chlorine-containing disinfectants commonly used in toilets will destroy taste buds in a short period of time if swallowed by mistake or even spit out directly. It will take several days to recover," Sun Jie said.

As soon as these words came out, the atmosphere in the conference room immediately changed. Many criminal police officers and forensic doctors came over in whispers. This was everyone's knowledge blind spot.

"That's not right." Liu Shuyuan interrupted everyone's discussion.

In this place, except for political commissar Wang, the other local criminal policemen are very careful about what they say. After all, Bai Song and others have special status, but there is no need to pay too much attention to what the four of them say.

"As I said before, we cannot consider suspects based on our knowledge. Just like you previously raised the issue of the 40-year-old difference mentioned in the "Adoption Law", most of them are not aware of it. You cannot judge others and think that others are not aware of it. I know." Liu Shuyuan said.

"Regarding this issue, I can only say that if Wang Liang were here, he might support me," Bai Song said: "People are generally divided into two types when it comes to unknown knowledge, passive and active."

"The so-called passive knowledge is the common sense we have. When we encounter corresponding things, if we have mastered the correct knowledge, we will naturally know. If we have not mastered it, we may not know that we are wrong at all. For example, this adoption law Legal content, for example, some counter-common sense knowledge, we will subconsciously think that we are right, and will not take the initiative to seek solutions." Bai Song said: "But sometimes when we encounter something that cannot be solved, we don't want to solve it at all. If you know something, you will take the initiative to ask for help. For example, ask others or search online."

This is normal. Even the police here didn't know about the adoption law, but Bai Song knew about it, so no one suspected it before. It was only when they met Bai Song that they realized they were wrong.

Bai Song didn't know what could make people lose their sense of taste, so he would take the initiative to ask. This was different from the "unknown" before.

The unknown of the former is that you don’t know that you don’t know.

…

"So, what should we do?" Hua Dong thought for a while and decided to ask Bai Song.

"I don't think people here understand this, so the murderer must have searched online. Then we will conduct big data screening and find out all the people who have searched for relevant knowledge in the past year. The IP is limited to Chengji County. There are no universities here, almost No one will look up this kind of knowledge online." Bai Song looked at Political Commissar Wang: "Do we have such technical means here?"

Political Commissar Wang smiled bitterly. It was not a matter of whether there was such a method, but that he did not know...

The conscience of heaven and earth, he is a political commissar and not the leader of the network security detachment... Although he has been a criminal police officer before, that was many years ago...

Sir, times have changed...

Seeing that Political Commissar Wang had a troubled expression, Bai Song took out his cell phone and called Wang Liang.

Do you really think our Captain Wang can only watch surveillance cameras?

Video recordings are actually electronic materials. A very critical point for any electronic evidence is to screen for effective evidence.

After handing over the matter to Wang Liang, today's work ends here. Because this is the East 7th District, it gets dark an hour later than that in Shangjing. Bai Song and others exercised for a while in the activity room of the county bureau. Only then did he return to his residence.

Wang Liang was faster than Bai Song imagined. He not only screened big data, but also traced the source and found the most suspicious mobile phone users.

Bai Song looked at it, and his eyebrows suddenly wrinkled, then relaxed again, and then wrinkled again.

Is this actually the deceased's own cell phone?

The person who usually has access to the deceased's cell phone... seems to be his 11-year-old adopted daughter... so? ? ?

Bai Song couldn't help but think of Yao Xin, that poor girl. This little girl is 11 years old. Could it be that she has also been abused in some way?

He was speechless for a long time after seeing the name. Is it so difficult to eradicate all the evil in this world?

Sun Jie and others also saw this name, and the three of them naturally understood what it meant.

Hua Dong sighed: "Bai Song."

Sun Jie and Shu Yuan also looked at Bai Song and said nothing.

Bai Song smiled slightly: "I'm fine."
