Tang Yang frowned slightly, he had a feeling that Wang Xuebing was definitely not a murderer, so who could it be?

Thinking of this, he looked at Bai Suqiu and asked, "Has anyone sent tea to Zhang Xuezheng in the past two days?"

"Nope. Bai Suqiu said with certainty.

"Think about it again. Tang Yang's tone of voice was very polite.

"Hmph, although I'm old, I haven't forgotten yet, and whoever goes to my house in the past two days will forget. Bai Suqiu said in a somewhat indifferent tone.

Although Zhang Xuezheng is dead now, the arrogance as the leader's wife has not disappeared, especially Tang Yang's way of questioning, which is like interrogating a prisoner and not giving her face at all, so she is very dissatisfied with Tang Yang now.

"Now that we know that Zhang Xuezheng has mouth ulcers, it's the two of you, if you can't find a third person, you will all be treated as suspects and accepted by our investigation. Tang Yang raised his eyebrows and continued to say very unceremoniously.

When Bai Suqiu heard Tang Yang's words, his face turned cold, and he shouted: "Our family's old Zhang just died, you don't take me in your eyes, what do you mean, ah!?"

Her voice was sharp and a little harsh, and then the door was slammed open, Xiao Chao was the first to rush in, looked at Bai Suqiu and said, "Auntie, what's wrong?"

And the dozen or so seven aunts and eight aunts outside also ran in and shouted nonsense.

Bai Suqiu took a deep breath, waved his hand and said, "It's okay, you guys go out." ”

Xiao Chao looked at Tan Song, Tang Yang and the others with a very cold gaze and said, "Don't think that my uncle is dead now, you can do whatever you want, if something goes wrong with my aunt, I will definitely not let you go." ”

After saying that, he turned around and walked out with his relatives.

With a bang, the office door slammed shut.

"I remembered!" At this time, Wang Xuebing suddenly shouted.

"What do you remember?" Tan Song hurriedly asked.

"It's the young man just now, Xu Chao, half a month ago, the leader asked me to buy medicine for him, when I walked to the gate, I just saw Xu Chao walk in, and he asked me what I was doing in such a hurry, I said that the leader's mouth ulcer was committed, go buy medicine. Wang Xuebing said.

Bai Suqiu thought about it thoughtfully, and also said: "I also remembered, I went to buy vegetables last night, and when I came back, Lao Zhang told me that Xiao Chao went on a trip, and he actually remembered to buy tea for him, I just listened to it at that time, and then went to cook, if it wasn't for Lao Wang to talk about it, I wouldn't be able to remember." ”

After speaking, he was stunned for a moment, his face changed, and he said in disbelief: "How is this possible, Xiaochao will not do such a thing." ”

"Nothing in this world is impossible. After Tang Yang finished speaking, he looked at Li Zeyu and said, "Arrest Xu Chao immediately!"

Li Zeyu immediately opened the door and walked out, and then heard Xu Chao's roar.

"What are you doing? Why are you arresting me? ”

Tang Yang immediately walked out, and Tan Song also followed.

Tang Yang saw Xu Chao, who had been handcuffed, and said, "Why did you arrest you, don't you understand in your heart?"

"What do I understand?!" Xu Chao roared angrily, as if he could breathe fire in his eyes.

Tang Yang didn't say anything more, looked at Li Zeyu and said directly: "First throw him into the detention room and stay for 24 hours." ”

Hearing Tang Yang's words, no one knew what he was planning, and if he arrested someone, he didn't interrogate them immediately, but actually sent them to the detention room.

Li Zeyu wanted to say something, but seeing Tang Yang's expression, he didn't dare to say it.

Tang Yang turned to look at Bai Suqiu, who was standing at the door, and said, "You can go back, we will inform you of any progress in the case." ”

"Is there really a problem with Xu Chao?" Bai Suqiu said hesitantly.

"We still need to investigate this, what we just said in it, you can't reveal a word to the outside. Tang Yang said solemnly.

"I understand this!" Bai Suqiu said.

"It's good to understand!" Tang Yang nodded and said.

Bai Suqiu sighed, didn't say anything more, and then left with her relatives and friends, although she didn't believe that Zhang Xuezheng was killed by Xu Chao, but now all the evidence has pointed to him, so she can only pray for God's blessing, hoping that all this is a coincidence, and it was not Xu Chao's doing.

Li Zeyu watched Bai Suqiu and them leave, and then asked, "Tan Bureau, why don't you interrogate Xu Chao immediately?"

"Now there is no evidence, you are interrogating, he will not say anything, and he is also Zhang Xuezheng's nephew, if he is tortured, he will leave people with a handle, and it will also cause us trouble. Tang Yang said.

"What should I do then?" asked Li Zeyu suspiciously.

"Investigate Xu Chao first, and investigate him clearly from childhood to adulthood. Tang Yang said.

Tan Song opened his mouth and asked, "What's the use of investigating this?"

Tang Yang looked in the direction where Xu Chao disappeared and said softly: "There are very few people who know about the existence of this toxin, and even if someone knows, it is some people who are engaged in biological research, or doctors, and this toxin is not something that anyone can get it." ”

"Understood, I'll investigate. After Li Zeyu finished speaking, he hurriedly left to arrange personnel to investigate.

Back in the office, Tang Yang saw that Wang Xuebing was still standing there, walked over and said, "You can go back now, remember, you can't leave Zhongzhou, we will look for you at any time if there is anything." ”

The next day, a light rain began to fall, and the whole city was foggy, as if covered with a light veil.

Some people are very nostalgic to walk in the drizzle, listening to the light sound of the fine rain hitting everything, while some people are in a hurry, their faces showing anxiety.

Tang Yang sat in Li Zeyu's office with his feet on the desk, while Tan Song sat on the sofa.

Li Zeyu was holding Xu Chao's investigation materials and handed them to Tang Yang, and said: "Look at the Tang Bureau, this Xu Chao didn't graduate from junior high school, he has been mixed in the society, and the bureau doesn't know how many times he has been in, but he didn't make any big mistakes, and the people below didn't embarrass him for the sake of Zhang Xuezheng's face." ”

Tang Yang took it and looked at it, and then handed it to Tan Song.

After reading it, Tan Song put the information on the desk, looked at Tang Yang and said, "Such a little gangster, even if there is someone behind him, I don't think he has the guts to kill Zhang Xuezheng." ”

Tang Yang took out a cigarette and lit one with some irritability, looked at the smoke drifting in front of him, and said softly: "Xu Chao is not a murderer, so who is it? Wang Xuebing? or Bai Suqiu?"

"I think Wang Xuebing is the most suspicious. Li Zeyu said.

"I think so too, when I was questioned yesterday, his expression and answer were full of holes, and he lied to us, which cannot but make people suspicious. Tan Song nodded and said.

After speaking, she looked at Tang Yang, who lowered her head and kept smoking, without saying a word, and after a while, she raised her head and said, "Li Zeyu, you are going to investigate Bai Suqiu, including the people around her, and they will investigate it for me." ”

"What about Xu Chao?" asked Li Zeyu.

"Lock him up first! When the case progresses, make sure that there is no suspicion and release him. Tang Yang said.

"Okay!" Li Zeyu turned around and walked out.

Tang Yang took a puff of cigarette, then spit it out lightly, looked at the slowly drifting smoke and said, "If it weren't for the fact that I wanted to find the person behind them, with my temper, I would have fucking killed them a long time ago, and I would have worked so hard to investigate little by little and let them lead the way." ”

Tan Song smiled bitterly and stopped talking.

Two hours later, Li Zeyu knocked on the door and walked in.

"The Tan Bureau, the Tang Bureau, have already investigated clearly. After Li Zeyu finished speaking, he handed the information in his hand to Tang Yang.

Tang Yang took a copy of the information in Li Zeyu's hand, opened it and read it carefully, then handed it to Tan Song, walked to the window by himself, and stood there pondering for a while.

Ten minutes later, Tan Song put down the information, frowned and said, "Old Tang, did you find any problems with this information?"

Tang Yang slowly turned around, and said with a somewhat cold look in his eyes: "Bai Suqiu, this person is very simple, there is nothing worthy of our attention, but there is one person who we have to pay attention to. ”

Tan Song looked at him and didn't speak, Tang Yang continued: "Bai Suqiu's younger brother, Bai Zhanxiong, this person has been abroad for more than ten years and has not come back once, but just the day before the crime, he suddenly came back, and Bai Zhanxiong is working in a biological research institute in the Western country. ”

Li Zeyu had already read all the information, listened to Tang Yang's words and asked, "This poison was provided to Xu Chao by Bai Zhanxiong?"

"This is only one possibility, and the other possibility, and the biggest possibility, is what he provided to Nguyen Van Ling. Tang Yang thought for a while and said.

The expression on Tan Song's face became very serious, and he said in a deep voice: "You mean, Bai Suqiu is the real murderer? But why did she kill Zhang Xuezheng, there must be a motive for killing." ”

Tang Yang said softly: " Let's make a bold inference, Bai Suqiu knew about Zhang Xuezheng and Yao Bihong's adultery a long time ago, which made her a little unbearable, until Yao Bihong's departure, Bai Suqiu's heart was a little better, but what she didn't expect was that Zhang Xuezheng met Yao Bihong by mistake, so she couldn't bear it, she felt aggrieved by herself and angry at Zhang Xuezheng, she wanted to retaliate, but she didn't have the opportunity and didn't have the guts, when we sent Yao Bihong's letter to the procuratorate, Chang Anping knew the news, and we had a lot of things in those two days, which just gave them a chance to prepare, this opportunity was Bai Suqiu's younger brother Bai Zhanxiong。 ”

"Bai Zhanxiong is their person, and he also knows that Bai Suqiu's history is here, so he naturally wants to use it. Tan Song said in a deep voice.

"Yes! This analysis can be explained, but we also need to interrogate Xu Chao, he is a key person, as long as he can answer me honestly a question, I can determine who the murderer is. Tang Yang nodded and said.

"I brought Xu Chao up. After Li Zeyu finished speaking, he opened the door and walked out.

"Take it to the interrogation room. Tang Yang also walked out.
