Zheng Kai didn't hide it, he did guess. Zheng Kai didn't know whether there was one murderer who killed Lu Dafu or several, but from Lu Guoqiang's performance, Zheng Kai felt that he could test it like this.

To be honest, Zheng Kai didn't think that the package was sent to Lu Dafu's wife alone. The murderer should know Lu Dafu's family very well.

Therefore, it is also clear that Lu Dafu's family relationship is not very harmonious. In this case, if the murderer wants to use Lu Dafu to negotiate conditions with the Lu family, then he must not put all his hopes on Lu Dafu's wife, in case Lu Dafu's wife doesn't care about Lu Dafu's life and death, then there is no need to talk about it.

If this murderer was smart enough, he should have sent a package to everyone in the Lu family, the content of the package may be the same, it may be different, but the purpose is the same, that is, to use Lu Dafu to negotiate conditions with the Lu family.

Of course, perhaps the most surprising thing for the murderer is that everyone in the Lu family doesn't care about Lu Dafu's life or death.

On the contrary, they very much hope that Lu Dafu will die. In this case, they can get a large amount of compensation.

The murderer did not get a response from the Lu family, so he chose to kill Lu Dafu in a fit of anger, moved Lu Dafu's body to a place only a kilometer away from the burning factory, and made the murder scene that appeared.

This is Zheng Kai's speculation. Not necessarily! But Lu Guoqiang certainly did not tell the police the full truth.

Zheng Kai is very sure of this. Soon, after the application for an appointment order, Su Qing took someone to Lu's house to start a search, and temporarily detained Lu Dafu's wife on the charge of not reporting it.

Things are going well. As long as the transfer order is in hand, the resident has no right to refuse the police search, and if he is blocked, the police can forcibly detain him until the search is complete, and will not consider whether to release the person.

As soon as Zheng Kai came out of the interrogation room, he met Su Lan head-on. When Su Lan saw Zheng Kai, she asked in surprise, "Didn't you follow Xiaoqing to check the Lu family?" "Su Lan is used to it.

During this time, Su Qing basically pulled Zheng Kai together in handling cases. The two spent more time together than the two sisters spent together.

"I don't need it over there."

"And I don't understand the search process." Zheng Kai replied honestly. Hearing this, Su Lan grabbed Zheng Kai's arm: "It just so happens that Yue Fang's autopsy report has come out, you can go to the forensic doctor with me to have a look, it is said that I found something related to you from Yue Fang's body." Zheng Kai was stunned for a moment.

"Isn't Yue Fang already sure that he died of tranquilizers? Why do you still need to do an autopsy? "When Yue Fang died, Su Qing was watching the monitoring in the monitoring room.

Zheng Kai was sitting in the corridor outside, and did not enter the monitoring room to watch together, so the details of Yue Fang's death only stayed at the death of tranquilizers, which was the same as Watson's cause of death.

Of course, Su Qing gave Zheng Kai something. That is when Yue Fang died, he was holding a note in his hand, and the content of the note was very simple: Zheng Kai, I saw you.

In such a sentence, Zheng Kai didn't figure out what he wanted to express. But apparently, the person who killed Yue Fang noticed Zheng Kai.

Moreover, Zheng Kai felt that this person was full of malice towards him. Su Lan didn't have much to say, Su Qing was originally in charge of this case, but Su Qing went to search the Lu family, so Su Lan took over the matter, and the two came to the forensic autopsy room.

Yue Fang's body was placed on the autopsy table. Except for the brain, Yue Fang's body was dissected very thoroughly.

Seeing Su Lan, the forensic doctor came over and said softly: "When Yue Fang died, there were a lot of congestion symptoms in his body, and his brain, heart and blood vessels all had a certain degree of excessive blood supply. "From a medical point of view, instead of soothing the spirit, the tranquilizer made the hematopoietic cells in Yue Fang's body start to work frantically, and the blood in the human body has a fixed range value, and if it exceeds or falls below this range value, it is very harmful to the body.

"In addition, the bones of his body also show signs of secondary development, but the secondary development rate of the bones is much slower than the speed of hematopoiesis, and it is not easy to be found without careful dissection." Secondary development?

Suddenly, Su Lan glanced at Zheng Kai. Zheng Kai's body shape at this time has also changed a lot from before.

Moreover, the change happened right after the fire at the factory. Zheng Kai's body, height, and muscles are much better than before.

Zheng Kai scratched his head: "This is my normal secondary development." Su Lan didn't look at Zheng Kai again, but asked the forensic doctor: "I heard that during the autopsy, some things were found in Yue Fang's body. Hearing this, the forensic doctor picked up the plate on the side.

On the plate was a filthy and filthy photograph. Just smelling it can make people sick and nauseous.

Su Lan didn't react. She is a policeman of the General Bureau, and she has seen too many corpses, and the disgusting smell that makes ordinary people smell sick to their stomachs can no longer cause too many waves in Su Lan's heart.

Zheng Kai is the same. Ignore the smell outright! The forensic doctor glanced at Zheng Kai more. It stands to reason that Zheng Kai is only an external employee of the archives, so he shouldn't have much chance to see the corpse.

But Zheng Kai's reaction was like that of an old criminal policeman for many years.

"This photo was taken out of the stomach of the deceased, and the content on the photo is related to Zheng Kai." Hearing the forensic doctor's words, Zheng Kai immediately leaned over.

Su Lan glanced at Zheng Kai angrily. After a closer look, Zheng Kai finally saw the content on the photo clearly.

For a moment, Zheng Kai was stunned. The contents of the photographs felt strange and familiar to him. Here is a group photo.

From the background of the photo, the time when this photo was taken should be twenty years ago. At that time, the Puzzle Kindergarten had just been renamed Zhi'an Kindergarten.

Zheng Kai is the first batch of children to enter the kindergarten after the kindergarten was renamed. And this group photo is a group photo of the children in Chinese New Year's Eve, Zheng Kai saw his appearance when he was a child in the lower right corner of the group photo, without a smile, giving people a posture of not approaching.

Zheng was shocked. The forensic doctor explained to Su Lan: "I have checked the database, but I can only find that the background is Zhi'an Kindergarten, and Zheng Kai is in this group of children, and he is this child who doesn't like to laugh." Su Lan also came closer.

Really! Zheng Kai when he was a child and Zheng Kai when he grew up, there were not many changes in appearance. The main thing is character.

When he was a child, Zheng Kai was very indifferent. But Zheng Kai was very easy-going when he grew up.
