"In this matter, Bai Zhanxiong is the key person, if he runs away, the case will be difficult to solve. Tan Song said behind Tang Yang.

"Zhang Xuezheng is dead, if Bai Zhanxiong, who is his brother-in-law, suddenly leaves and returns to the Western Kingdom, it will really be three hundred taels of silver here, so he will definitely not leave, since it is acting, of course there must be a perfect ending, and he doesn't think we will catch him. Tang Yang said in a low tone.

"I'm afraid that after Bai Suqiu goes back, he will tell him what we have, and it will be troublesome. Tan Song said.

"If our analysis is correct, Bai Suqiu will definitely tell Bai Zhanxiong, but don't worry, he will definitely not leave, because people with high IQ are very conceited, and we are so sure that the murderer is Xu Chao, which can also make him feel safe for the time being. Tang Yang suddenly smiled indifferently.

After a while, the two of them came to the interrogation room and saw that Xu Chao had been handcuffed to a chair, this guy was obviously in poor spirits, his eyes were bloodshot, and he glanced at Tang Yang a little blankly.

Tang Yang walked up to him, smiled and said, "I see you were quite able to jump yesterday, what's wrong with this today, it's the same as a frosted eggplant." ”

Xu Chao lowered his head and didn't speak, Li Zeyu sneered and said: "This guy made a fuss all night last night, and when I went to mention him just now, he was still asleep." ”

"On the day of the 8th, did you send tea to Zhang Xuezheng?" Tang Yang asked directly.

Xu Chao still didn't speak, and Tang Yang continued: "Boy, I want you to answer honestly, because after our investigation, all the evidence points to you, if you don't answer, you will die." ”

Xu Chao slowly raised his head and said in a hoarse voice: "How could I kill my uncle." ”

"I don't believe it either, that's why I came to you, first, we are to catch the real murderer, and second, it is also for you kid to be able to wash away the grievances. Tang Yang glanced at him and said calmly.

"On the 8th, I brought tea to my uncle. Xu Chao hesitated for a moment but said it, he also knew that it must be himself if he didn't say that he was unlucky.

"Who received the tea?"

"My aunt!"

Tan Song and Tang Yang glanced at each other, and Tang Yang said, "Li Zeyu brought him back." ”

"Yes!" Li Zeyu said.

Tang Yang and Tan Song walked out of the interrogation room, and Tan Song said: "If Xu Chao didn't lie, then Bai Suqiu was the most suspicious. ”

Tang Yang stopped, but did not speak, until Li Zeyu came back, he said, "Find a few people and follow me to arrest Bai Suqiu." ”

After saying that, he walked quickly downstairs.

Tan Song looked at Tang Yang's back and wanted to say something, but he didn't say anything, just returned to the office with a worried face.

Family home.

Bai Suqiu sat on the sofa in the living room, and next to her sat a young man in his thirties with glasses.

"Eldest sister, don't worry, what can those police do if they find out the source of the poison, as long as we don't admit it, they don't have evidence, but I really admire them, they actually know the existence of this poison. The young man said.

"Alas, for so many years, he has had a woman outside behind my back, and he also has a son, I really hate it, but now that I think about it, it's a little unworthy. Bai Suqiu sighed and said.

A cold cold glow flashed in Bai Zhanxiong's eyes, and he put his arm around Bai Suqiu's shoulder and said, "Sister, how has he treated you for so many years, have you forgotten? Now that the incident has happened, there is nothing to regret." ”

At this moment, there was a gentle knock on the door, Bai Suqiu stood up and walked to the door, opened the door and saw Tang Yang, his face changed, but he quickly returned to normal.

"Deputy Director Tang, is there any progress in our family's Lao Zhang's case?" Bai Suqiu looked at Tang Yang and asked sadly.

"That's right. Tang Yang smiled and nodded.

"Come in, please. Bai Suqiu smiled reluctantly.

Tang Yang walked in with Li Zeyu and five other police officers, saw Bai Zhanxiong sitting there and asked, "Who is this?"

"This is my younger brother, I haven't been back for more than ten years, but I didn't expect that as soon as I came back, Lao Zhang would be gone. Bai Suqiu hurriedly said, her eyes were red after speaking, and tears fell down her eyes.

Tang Yang glanced at Bai Suqiu, and said in a cold tone: "Since they are here, it just saves us trouble." ”

As soon as Tang Yang's words fell, two police officers walked towards Bai Zhanxiong and handcuffed him without saying a word.

Bai Suqiu was stunned for a moment, and then shouted sharply: "What are you doing?"

As soon as she finished speaking, the two police officers also handcuffed her, Bai Suqiu's face changed drastically, her body trembled, and she didn't make a sound for a long time with her mouth open.

"What do you mean by that?" Bai Zhanxiong asked calmly.

"Take it away!" Tang Yang ignored him and waved his hand.

"Yes!"

The five police officers escorted Bai Suqiu and Bai Zhanxiong away, while Tang Yang looked from room to room, and finally came to Zhang Xuezheng's study, and found that there was some chaos inside, obviously after Zhang Xuezheng had an accident, no one had come here.

Tang Yang turned around, and at this time Li Zeyu walked in and asked suspiciously, "Tang Ju, what are you looking for?"

Tang Yang stood in front of the desk, picked up a book and flipped through it, then put it down, and opened the drawer of the desk, which contained nothing except some documents.

Li Zeyu stood there watching Tang Yang wander around the small study, and he didn't know what he was trying to find.

After a while, Tang Yang didn't find anything valuable, walked out, went to the kitchen to take a look, and then went to the bathroom again.

There was a garbage basket behind the door of the bathroom, Tang Yang was not too dirty, he bent down and turned it over, and suddenly a plastic packaging bag appeared in front of him, and he picked it up with two fingers, this is the packaging bag of disposable syringes.

"Li Zeyu, put this away and go back to check the fingerprints on it. Tang Yang shouted.

Li Zeyu immediately walked out of the bathroom, and he didn't know where to find a convenient bag, and put the packaging bag of the disposable syringe in it.

Immediately afterwards, Tang Yang simply picked up the garbage basket and poured out all the contents inside, and then a smile appeared on his face.

Li Zeyu squatted down, picked up a disposable needle on the ground, lifted it up and looked at it, there was still not much liquid shaking in it.

"Let's go, our Zhang Xuezheng's office. Tang Yang stood up and said.

"What are you doing there?" Li Zeyu put the syringe in the convenience bag and looked up and asked.

"If you find the tea that Zhang Xuezheng drank, you should find something. After Tang Yang finished speaking, he walked out.

The two of them went downstairs, Tang Yang looked up and found that most of the windows were open in the entire building, and many people's heads poked out and looked downstairs.

"I estimate that many people now know the news that Bai Suqiu was arrested. Li Zeyu said.

Tang Yang walked over to the officers in the other two police cars and said, "You guys bring the suspect back first." ”

After speaking, he turned around and got into the car and went to Zhang Xuezheng's unit.

A moment later, Tang Yang and Li Zeyu came to Zhang Xuezheng's office and finally found an iron box of oolong tea on the space of the bookshelf.

Li Zeyu opened the box and saw that there were small packaging bags inside, took out a bag and searched carefully for a while, and finally found that there was a small needle eye on it.

"Tang Bureau, look!"

Tang Yang took it in his hand and looked at it, and said, "Let's see if there are any other ones on it?"

Li Zeyu took out all the small packages of tea inside, there were about a dozen bags, without exception, there was an imperceptible needle eye on it.

"Put it away, let's go back. Tang Yang said.

The two of them walked downstairs quickly, got into the car, and Li Zeyu said, "Do you want to take it for testing first?"

"There's no need for that. Tang Yang said with a sigh.

In the office, Tan Song received the following report that Bai Suqiu and Bai Zhanxiong were brought back, which made him feel a little bottomless, after all, there is no solid evidence that they are murderers, so arresting them like this, as long as they insist that they didn't do it themselves, they have no way at all, but they will cause trouble for themselves.

With a bang, the door of the office was pushed open, Tang Yang stood at the door and beckoned, and said, "The evidence has been found, go and interrogate Bai Suqiu now." ”

Tan Song listened, finally let go of his heart, and hurriedly walked out.

When he came to the interrogation room, Tang Yang didn't talk nonsense, he directly put the needle and tea on the table, and said in a cold voice: "Bai Suqiu! ”

Seeing the things on the table, Bai Suqiu's eyes actually showed a color that was almost desperate, but it quickly returned to normal.

"Bai Suqiu! found your fingerprints on this. Tang Yang picked up the tea leaves in a cold tone, and continued: "We found a box of oolong tea in Zhang Xuezheng's office, and there are more than ten such small packaging bags in it, and on each bag, there is a needle eye, after testing, the liquid remaining in the needle tube is the toxin in Zhang Xuezheng's office, and there is also this poison in the tea. ”

"Bang!"

Tang Yang suddenly slapped the table and said fiercely: "Zhang Xuezheng has an affair, and you have always held a grudge, right? And he also had a child with that woman, you hate him even more, right?"

"I don't know what you're talking about, and besides, I've lived with Lao Zhang for more than twenty years, and I've never quarreled, how could I kill him. Bai Suqiu said calmly.

"Bai Zhanxiong is already explaining the problem, and as soon as his confession comes out, you won't even have a chance to make meritorious contributions, and you will fall into a situation where you can't recover, think about it yourself. Tang Yang said coldly.

After speaking, he waved his hand and said, "Let's go out and give her time to think about it." ”

Immediately, the three of them walked out of the interrogation room, and Li Zeyu said, "I'll interrogate Bai Zhanxiong now." ”

"! you go and interrogate a fart, if that guy is so easy to confess, why should I find Bai Suqiu first. Tang Yang scolded angrily.

"Didn't you say that Bai Zhanxiong was already explaining the problem?" Tan Song also said with a wry smile.

"Hehe, compared to Bai Zhanxiong, Bai Suqiu is easier to open a breakthrough here, no matter how strong and cunning a woman's mind is, she is also a woman. Tang Yang smiled.
