The facts of the case are actually very simple.

Two days ago, the adopted daughter who brought toiletries to the deceased mixed disinfectant into the water in the deceased's toothbrush cup. The deceased took a sip and immediately spit it out. He then asked the adopted daughter what happened, and the adopted daughter said that she poured the water in the wrong way.

It was winter, so there was naturally no such thing as tap water. The water was in large vats, and the water for daily use was placed in bottles next to the vats. The adopted daughter argued that she had poured the water in the wrong place, and the deceased did not think of anything else, but he was angry and beat the adopted daughter.

As a result, the deceased had no taste in his mouth for the past few days. Nothing he ate tasted good, and even a kiss from his wife had no taste. He felt numb. He asked the village Mongolian doctor, and the doctor said it would be fine in a few days, so the deceased did not take it too seriously. However, he drank a little more than usual because alcohol is a stimulant, and he felt the effects a little.

The night before, the wine that the deceased drank was replaced with a mixture of pesticides and wine. The deceased, who drank too much, had no idea and drank it all. Then the poison took effect and he died in the house.

Then, the adopted daughter entered the house and took away the bottle of mixed poison. Then, putting on gloves, she stained the pesticide bottle with the deceased's saliva and fingerprints and left it there to disguise the suicide scene.

In fact, there were footprints of a girl at the scene.

However, the same problem arises. It is normal for the deceased to have disinfectant at home, but where did he get the pesticide?

Not to mention other places, the owner of the pesticide store in the town had already looked for it, and he had no recollection of selling pesticides to anyone in this village. Of course, the owner couldn't know everyone in the village, but he certainly had never seen the girl buy pesticides.

This means that either the girl went to a faraway place to buy pesticides, or someone else assisted or instructed her to do so.

This is an issue that needs to be resolved urgently. Now we still need to interrogate the girl to find out if she was not instructed to do so.

If a minor is instigated to commit a crime, the instigator is not identified as an instigator, but as an indirect principal offender. In layman's terms, the principal offender.

The interrogation of the girl went smoothly and what happened was as described above.

In addition, the girl had injuries on her body, which were caused by her adoptive father beating her three days ago. The disinfectant in the house was thrown away and was also found nearby.

However, nothing else could be learned from the girl's timid tone, but it was true that she personally participated in the murder.

…

"It's not that simple. This girl is obviously being mind-controlled by someone." Bai Song said.

"But it should be her who is searching on the man's phone, right?" Huadong asked.

"If it was before, I would have thought so too. After all, judging from this case, only this girl had the right to use the deceased's phone. But now we can't think about the problem so simply," Bai Song's thinking was a bit divergent: "Those women who were related to the deceased may all have problems."

This case has always felt weird.

In order for a case to be established, it is not only necessary to commit the crime, but also what is behind the crime.

If the girl was not the main culprit, the direction of consideration would change - what was so special about the deceased that someone would deliberately kill him?

Analyzing the circumstances of the deceased, although there were more than a hundred sheep, there was nothing special.

The reconnaissance reached a stalemate at one point.

…

"Captain Bai, isn't the case solved? The girl has identified the murderer." Political Commissar Wang was a little excited. In his opinion, the case could be determined and closed. All that was left was to arrange for this murderer to be placed in a shelter for education.

"Many logical problems have not been properly resolved." Bai Song also did not know the exact time when the inspection team would withdraw: "But we will investigate the case to the end."

"Yes, we must get to the bottom of this," the local director said with a wry smile, "We will report to you on the progress as soon as possible."

Bai Song could see that the local police had made their intentions very clear. Since the case had been solved, they should just handle it as an ordinary case. There was nothing extra to consider.

This was obviously not what Bai Song wanted to accept.

Because of this, the afternoon meeting was not arranged pleasantly.

…

At the same time, in Shangjing City, Wang Liang also faced some problems.

He now has the highest authority, but it is not as easy as Bai Song has imagined. Wang Liang does not feel comfortable in the Science and Technology Bureau. Many cases he wants to investigate are very difficult. If it were not for his technical skills, many things would not be done.

Bai Song was not aware of this matter, and had been looking for Wang Liang for help according to the situation at the Tianhua City Bureau, but this caused Wang Liang a lot of trouble.

Wang Liang has not had a good time these days, but he still monitors the work arranged by Bai Song.

…

Linyang City.

Bai Song is preparing to merge the current cases into one.

He suspected that the two cases were related.

If it weren't for this case, this situation would hardly have occurred. Logically speaking, there shouldn't be a situation where someone induces a girl to kill her adoptive father.

Logically, this has become a problem that needs to be solved urgently.

…

Even though Bai Song and others are geniuses in solving cases, the investigation is extremely difficult given the climate, cultural environment and current reality (Chinese New Year).

Especially since everyone is a member of the inspection team, it is impossible for them to investigate the case clues in a down-to-earth manner.

So, at present, from the local point of view, the case has been solved very easily; but from the perspective of Bai Song and others, the case has only just begun.

So, the case officially begins.
