The police went to investigate whether what Mr. Huang said was true or false, while Zou Cheng went to ask the people at the police station, did the investigation be clear?

The people from the police station have already investigated and brought the list to Zou Cheng.

"Inspector Zou, this is Yi Ziqi's consumption during this time, to be honest, these consumption is really provincial. The officer said.

"Is this the last two months?" asked Zou Cheng.

Zou Cheng himself was also surprised, because Yi Ziqi's consumption was really small, as if he had no additional expenses.

The police officer nodded and said, "Yes, Inspector Zou, this is all Yi Ziqi's consumption, we have also checked his bank card, and cash consumption is also counted here." ”

Zou Cheng shook his head, it seems that Yi Ziqi's life is very poor, so it really doesn't look like someone killed Yi Ziqi for money.

"Inspector Zou, since Yi Ziqi is so economical, why is there such a large amount of expenses here. Liang Yingqi looked at the 3,000 yuan expense on the bill, and felt a little abnormal.

Zou Cheng also saw that indeed, this is not in line with Yi Ziqi's consumption habits.

The cost of 3,000 yuan, Zou Cheng took a look, it was a laboratory.

"What is this?" asked Zou Cheng to the officer.

One officer said, "It's a lab, it's going to help test something, identify something." ”

In other words, Yi Ziqi has something that needs to be tested and identified, and he sent it here. Zou Cheng felt that this was the only possibility.

After looking at the consumption time, Zou Cheng said: "The things may still be in the laboratory, call them." ”

The police called the laboratory, but the laboratory said that they had already given the things to Yi Ziqi.

And the time was the day Yi Ziqi was killed, Zou Cheng asked the police: "Did you find anything on Yi Ziqi's body?"

The officer shook his head and said, "I didn't find anything related to this lab." ”

Zou Cheng closed his eyes and began to recall, since the people in the laboratory said that they gave things to Yi Ziqi, then they should have given them.

But what about things?

Zou Cheng recalled Guo Jun's words, Guo Jun said that when he scared Yi Ziqi, Yi Ziqi threw all his instruments and things in the place.

So is this thing including what Yi Ziqi sent to the laboratory?

If so, why can't I find it?

Did the murderer take it away?

It is very likely that the murderer took it away, because the murderer may have killed Yi Ziqi just to cover up something.

But when Yi Ziqi died, the instrument was not around, so that thing may not be around either, so after the murderer killed, he should not be able to find anything.

So where are the things scattered in the mental hospital?

Zou Cheng remembered the patient in the mental hospital, the patient who had been living in it.

"Do you remember that patient likes to collect letters, and said that the doctors and nurses in the police have not come to pick up letters for a long time?" Zou Cheng said to the police officer.

The officer nodded and said, "Yes." ”

"Go to his room and look for it, Yi Ziqi's things should be there. Zou Cheng thought that Yi Ziqi threw everything on the place when he was scared by Guo Jun.

Then he chased Guo Jun out, and then the patients in the mental hospital saw something on the ground and thought it was a letter that had been sent, so he collected it himself.

He took the things back to his room and put them away, and what happened after that was probably that Guo Jun was caught by Yi Ziqi.

After the two separated, Guo Jun left the mental hospital, and Yi Ziqi went back to find his things, but was killed by the murderer hiding in the mental hospital.

This should be the timeline, so Zou Cheng thinks that things are still in the mental hospital.

In fact, the police officer had already asked the people in the laboratory just now to tell them what Yi Ziqi was sending to.

But the people in the lab said they had a non-disclosure agreement, and if someone from the police department wanted to know, they needed an investigation warrant.

But now who has the time to get an investigation order, Zou Cheng directly asked the people from the police station to look for it in the mental hospital, and among the many letters in the patient's room, Zou Cheng thought that there would be something left by Yang Ziqi.

Sure enough, after waiting for a while, the officer ran back with a bag of evidence in his hand, which contained something like a letter.

It looks like it says the laboratory, and it seems that it is something sent by Yang Ziqi.

"Open it and see what's inside. Zou Cheng said.

Officers opened it and found a forensic document inside, as well as a skeleton-like object.

"What is this thing?" the officer looked at the skeleton in his hand.

Zou Cheng looked at the identification data and said: "This is said to be a human skeleton, a human finger bone, and the fifth knuckle bone at the end of the right upper limb." ”

"It's the little thumb. Zou Cheng finally said.

"Human bones?" the officer asked, frowning.

Zou Cheng said: "That's what it says, I think we'd better identify it ourselves." ”

"Yes. The police officer immediately took the things and went to the police station to identify them, although the laboratory had already identified them, but they still couldn't believe it if they didn't identify it.

"Inspector Zou, the results have already been released. After a while, the police officer called Zou Cheng over.

Zou Cheng took Liang Ying and walked in.

The staff inside saw Zou Cheng come in and said, "Inspector Zou, the preliminary examination results of the phalanges show that the phalanges have no particles, no macroscopic pores, and no streaks. ”

"It can be concluded that this phalanx belongs to a woman about 15 years old. ”

The staff's words made Zou Cheng and Liang Yingqi understand that this thing is indeed a human bone.

Liang Ying asked, "How can Yi Ziqi have human bones in his hands?"

It seemed that he was not sure, so he found a laboratory. Zou Cheng thought that Yang Ziqi didn't know what the composition of this bone was, otherwise he wouldn't have found a laboratory to identify it.

"But the laboratory has already given him the information, don't you think he should already know?" Liang Yingqi thought that Yi Ziqi should already know.

Zou Cheng nodded and said, "Yes, Yi Ziqi should be suspicious, so he sent it for identification, and then determined what he thought in his heart." ”

But he had a plan that night, which was to go to a mental hospital and die. ”

"His death may have something to do with this finger bone. Liang Yingqi felt that the appearance of this phalange would not be inexplicable, and it must have something to do with Yi Ziqi's death.

Zou Cheng also thinks so, this finger bone may be the most important thing that caused Yi Ziqi's death.

"Is it true that there is a cemetery under the rumor hospital?" the officer said.

"Yi Ziqi's bones are not necessarily found from a mental hospital. Zou Cheng felt that it was still uncertain.

"Can you still compare DNA?" Zou Cheng asked the staff.

The staff nodded and said, "Yes." ”

"Very well, find out the owner of this finger bone. Zou Cheng gave him this task.

"By the way, there's one more discovery. The staff shouted to Zou Cheng.

"On this bone, there are traces of zinc phosphide, and zinc phosphide is a key ingredient in rat poison. The staff's words made Zou Cheng directly think of something.

Zou Cheng said, "Do you remember when I went to Mr. Huang's basement?"

"What's wrong?" the officer asked.

"There's a lot of rat poison down there, and there's a lot of rat trapping tools. Zou Cheng said.

When the police heard Zou Cheng's words, they immediately said: "Mr. Huang, they invited Yi Ziqi to their own house, and they just went to see their basement, maybe this bone was found by Yi Ziqi in Mr. Huang's basement." ”

Indeed, Zou Cheng is this inference, and Yi Ziqi may have found this bone there.

The officer was embarrassed and said, "But we know that this inference does not seem to be enough to support us in getting a search warrant." ”

Zou Cheng said: "Let's just say that I think the bones were found in Mr. Huang's house. ”

Although there is no evidence now, Zou Cheng can be regarded as a golden signboard, and at this time Zou Cheng feels that he cannot be indecisive.

Hearing Zou Cheng's words, the police officer said with some joy: "If Inspector Zou comes forward, he should be able to get the search warrant tonight." ”

"Inspector Zou, you wait for the search warrant, I'll go over first, I'll keep an eye on them. "The officers felt they had to keep an eye on them now and couldn't let them run.

After the police officer finished speaking, he ran away, and Zou Cheng waited for a search warrant at the police station, hoping to come down quickly.

While Zou Cheng was waiting for the search warrant, the police officer in charge of reading the thermal imaging data ran over and said, "Inspector Zou, we have made a new discovery. ”

"What discovery?" asked Zou Cheng.

This figure-shaped thing is Guo Jun, and he also admitted it, but behind this figure, there is also something that generates heat. The officer said.

"This red circle. The officer pointed to a red circle and said to Zou Cheng.

Zou Cheng asked, "Do you know what is formed?"

"Still working on it. The officer said.

"Okay, find this thing. Zou Cheng felt that there was a fourth person present in the mental hospital at that time, so this circle behind this may be proof of the presence of the fourth person.

Although it is now preliminarily determined that Mr. Huang has a problem, evidence is also needed, and without evidence, how can you prove that he killed someone.

The police went down to continue their research, and Zou Cheng waited for the search warrant while asking the police officers who went to the village about the situation.

"I've been staring out there and there's nothing out of the ordinary. "The news from the police officer.

But after half an hour, the officer said: "I heard a voice in the room, it seemed to be the voice of Mr. Huang's wife, no, I have to go in and have a look." ”

"Be careful, we'll come right over. Zou Cheng said.

The police officer in front hung up the phone, Zou Cheng immediately wanted to bring someone over, and a police officer said: "Inspector Zou, our search warrant has not come down yet." ”

"What do you want a search warrant, don't wait, hurry up. Zou Cheng shouted.

The last time Mr. Huang's wife saw her, she felt weird, she might want to say something, but with Mr. Huang there, she was inconvenient.

Now the police said that they heard her scream, maybe it was an accident, so Zou Cheng felt that he didn't care about the search warrant at this time.

And there was a scream in the room, which didn't require a search warrant at all, they could just rush in.
