In the interrogation room.

There was only a long table in the small room, with a spotlight on it, and the light made the faces of the people next to him pale.

Du Xueming was sitting on a chair, feeling anxious and restless. He would hold his head with his hands and pound on the table, and then stand up and yell at the door, demanding to be let out.

What's more, he violently kicked the chair he was sitting on. Fortunately, his hands were handcuffed, otherwise the whole room would have been torn down by him.

Xu Yao did not rush to interrogate Du Xueming, but stayed in the monitoring room and observed Du Xueming's every move.

The more Xu Yao looked up, the deeper the doubts in his heart. He didn't know whether Du Xueming's current behavior was deliberately pretended or it was his nature.

If it was an act, he had to admire his acting skills. Now he portrayed a man who was in pain of losing his wife, and his portrayal was very vivid.

Five minutes later, Xu Yao pushed open the door of the interrogation room and walked in calmly.

Du Xueming saw someone coming in, and immediately opened his eyes and shouted excitedly:

"Police comrade, Captain Xu. I have been waiting for you to come, what on earth are you doing? My wife is dead, and you actually locked me up here and did nothing."

"Mr. Du, don't get excited, haven't I already come?" Xu Yao motioned Du Xueming to sit down first.

Du Xueming finally suppressed his anger, sat down on the bench, and began to speak again:

"Who knows what it will take for you to let me go? Ask me whatever you want to ask me. I only ask you to let me go so I can go back to see my wife."

Xu Yao raised his eyes and glanced at Du Xueming carefully, "Mr. Du, it seems that you and your wife have a very good relationship. We, the police, can only express our deep regret for your wife's death, so the police are now working hard to find the murderer."

As Xu Yao spoke, he placed the button that Chen Xinhua had once held in her hand on the table.

"Mr. Du, do you remember this button?"

Doctor Du Xueming carefully examined the black button in the plastic bag and said, "This kind of button? You should have seen this kind of button on most suits now!"

"You are wrong. It is not on most suits, but on most custom-made suits. Mr. Du, do you have this kind of button on your suit?"

At this time, Du Xueming realized that this button was the one she held in her hand after her fifth sister died.

"Captain Xu, what do you mean? Do you really suspect me?" Du Xuemin couldn't help but sneer a few times. It turns out that you not only suspect that I killed my wife, but now you also suspect that I killed my fifth sister. "

Xu Yao said in a cold tone, "It's not suspicion, it's real evidence."

After he finished speaking, he continued and threw the plastic bag containing cyanide onto the table.

"This, you should be familiar with it, right?"

"What's wrong with knowing it?" Du Xueming answered indifferently.

Xu Yao said, "Then do you know where it was found? It was found from under the bed where you and your wife lived together day and night.

Your wife Chen Xinli died from this poison.

As a doctor, you should know very well that hydrogen is a highly toxic substance. As long as a certain amount is ingested, one will die immediately within seconds or even hours.

Mr. Du Xueming, since you say that we, the police, have wronged you, then please explain the two clues we have found now. How do you explain it?

This button has been confirmed by us, the police, as the button that fell off the sleeve of the black suit in your closet.

The cyanide drug was in the bed board in your bedroom."

Du Xueming's face began to show panic when he heard this. He should have known that the evidence was not in his favor.

"Captain Xu, comrade police officer, I don't know why you are suspicious of me? I really don't know why the buttons on my suit are in my fifth sister's hand.

As for the cyanide, it was indeed me who brought it, but I only used it to kill insects.

You police asked me to prove it, and I can only say that I didn't do it and I have a clear conscience."

Xu Yao was furious, and he swept the lamp on the table to the ground with a snap. He had asked Du Xueming countless times, and every time he answered very calmly.

Even if a lie detector was used, the data did not show that he was lying.

What a person with strong psychological quality this is. All the pressure that Xu Yao had accumulated recently burst out. He stood up angrily, reached around and grabbed Du Xueming's collar directly.

"Asshole. Now that the evidence is solid, you still want to deny it?

Well, if you don't want to tell me, I'll tell you. Chen Xinhua is your sister-in-law, and she has become your pawn without knowing it.

You did everything you could to get Chen Xinhua out of the mental hospital, and in fact, Chen Xinhua has been slowly recovering during the treatment.

You used her anger towards your second brother Chen Xinhua to create a perfect murder plan. .

You just created the story that a ghost murdered someone and escaped the crime. This move of yours is really a good one. Even if the police find out that Chen Xinhua is just pretending to be a ghost to commit the crime, as long as you don't reveal any clues, the police will not trace him back to you after catching him."

After listening to this, Du Xueming shouted loudly: "It's unfair, Captain Xu, may I ask why I did this? I have no reason to do this."

"You do. Because you have strong ambitions. "Man dies for wealth" has existed since ancient times."

Then, Du Xueming began to laugh loudly, "What a joke. The police officer means that I wanted to seize the Chen family's property and family business, right? Hahaha!"

The interrogation room was filled with Du Xueming's indistinct laughter.

Xu Yao waved his hand and punched Du Xueming in the face.

"I always thought that your wife Chen Xinli was the ambitious one. She wanted to become the heir of the Chen family, so she used Chen Xinjiao to eliminate his brothers and sisters, your competitors for inheritance.

But now it seems that your wife was just listening to your advice, and in the end you were the one manipulating everything behind the scenes.

Chen Xinyu, the eldest son of the Chen family, died. The second son and your wife all died at your hands.

Did you feel that Chen Xinjiao had no value to you, or did you decide that Chen Xinjiao was out of your control, so you wanted to kill her?

Now that the evidence is clear, Du Xueming, I advise you to truthfully confess your crime, so that I can plead with the judge. "

Du Xueming suddenly calmed down, his face ashen. "So, you police have completely determined that I am the murderer, right?

Even if I keep saying that I am not the murderer, you will not believe it. Now you should wait for me to sign and seal, and then send me to the execution ground.

Very good, is this all you police are capable of?

I don't have the energy to explain to you now. My wife lost her life in this fight. The funny thing is that you suspect me!

It's up to you."

After Du Xueming said these words, he sat on the chair in silence.

Xu Yao couldn't do anything to him. "Du Xueming, even if you don't confess your crimes, it doesn't mean we can't convict you."

Xu Yao stood up, sorted out the documents on the desk, turned around and walked to the door. He looked back at Du Xueming, only to see that his eyes were dull and he was looking forward with a sad expression.

Xu Yao's thoughts were tangled again, and he felt that some link was not connected here, but he couldn't find the flaw after thinking carefully.
