As soon as Zhang Yu saw Ni Ni shaking her head, he immediately realized that the target person had not been found.
According to Cao Dahua, there is no footage of the target person leaving the bar in the surveillance cameras. People can't fly, right?
Zhao Xuan obviously did not want to stay in this place of right and wrong for a long time, so he said goodbye to Zhang Yu.
Zhang Yu nodded with a smile and said, "Okay, you guys go back and rest first. We'll see you tomorrow."
Zhao Xuan took Luo Xiang's hand and walked out. As Luo Xiang walked, he turned back and waved to Zhang Yu, "See you tomorrow, don't be late..."
After saying this, she suddenly said again, "Teacher Su!"
Follow, stop.
Hearing her words, Zhao Xuan and Meng Qiushi both stopped, looked back, and then greeted, "Teacher Su." "Teacher Su."
Several people walked over from the police registration desk. One of them, a middle-aged woman, said: "Luo Xiang, Zhao Xuan... you are all here... such a coincidence..."
Zhang Yu has been staring at the people coming out. Of course, he can't see anyone suspicious. After all, almost all the people who have registered are fine.
This Teacher Su has wavy permed hair and a medium build, about 165cm tall. He is wearing a red T-shirt, gray casual pants, black casual shoes, and a pair on the chest that are not too small, covering the neckline of the T-shirt.
Stand up.
Zhang Yu guessed that Teacher Su was probably a teacher at Wunan University. He was already a student at Wunan University, so he might not look up when he saw her in the future, so there was no harm in saying hello.
Seeing Teacher Su walking up to Luo Xiang and the others, he also walked over and said, "Hello, Teacher Su."
"Hello... Excuse me, are you..." Teacher Su seemed a little confused because she had never met Zhang Yu.
Luo Xiang quickly introduced, "Teacher Su, his name is Zhang Yu, he is a student our teacher recruited this year."
"You are..." Teacher Su was inevitably impressed by Zhang Yu. This was because Zhang Yu's reputation had already spread throughout Wunan University before he came to school.
Luo Xiang continued to introduce, "Zhang Yu, Teacher Su is an associate professor in our Department of Industrial Manufacturing at Wunan University... He also has many contacts with our Department of Chemistry... Our experimental equipment is all linked to Teacher Su's..."
"Please take care of Teacher Su in the future..." Zhang Yu said earnestly.
"You're welcome...you are Professor Yu's disciple...you will definitely have a bright future in the future..." Teacher Su said politely with a smile.
Um?
Zhang Yugang was about to continue being polite, but something suddenly occurred to him. Cao Dahua had mentioned before that the call record was about indecent photos of Zhou Ming, a professor at the Industrial Manufacturing Department of Wunan University, and female students in the classroom. And these photos still have to be sold.
For the deceased.
What a coincidence, Teacher Su is also from the Department of Industrial Manufacturing.
However, according to Fan Zhongping's description, the person who came into contact with the deceased was a man with parted hair, not a woman.
"This is not the place to talk. Let's go first and talk later." Teacher Su said when Zhang Yu didn't speak anymore.
"Okay, Teacher Su, let's go together." Luo Xiang said.
"Teacher Su, let's go." Zhao Xuan also said.
"Wait a minute!" Zhang Yu said hurriedly when he saw that they were about to leave.
Teacher Su's raised steps immediately stopped and did not make a sound.
She didn't speak, and Zhao Xuan said, "Is there anything else?"
"Uh..." Zhang Yu hesitated for a moment. Just when Teacher Su proposed to leave, Zhang Yu suddenly remembered something. He then said: "Teacher Su, are you here alone?"
Most of the people who come to the bar are a few people. Naturally, there are also one person who comes, but it is relatively rare. For people like Teacher Su who go to the bar to drink alone, it does not mean that it is not possible, at least there should be some explanation.
More importantly, Luo Xiang just said something, that is, "Teacher Su also has many contacts with our chemistry department, and our experimental equipment is linked to Teacher Su's."
Furthermore, Cao Dahua also said that the deceased was poisoned by potassium cyanide. If the potassium cyanide was too little, the deceased would not die immediately. If the rescue was timely, he could still be saved. If the potassium cyanide was too much, the deceased's
The death would be extremely horrific. Although the dose of potassium cyanide administered by the murderer was slightly too high, the purpose should be to ensure that the deceased would die immediately after being poisoned, without any chance of rescue.
The person who can do this should be someone who understands chemistry.
It is obviously not impossible that the three of Luo Xiang were together at that time. And this teacher Su, who knows chemistry, seems to be the same person.
"I came here alone." Teacher Su said.
"Why come here to drink alone?" Zhang Yu asked.
"I often drink alone...is there any problem..." Teacher Su said.
"The problem...is...no..." Zhang Yu spoke very slowly, but his eyes looked up and down at Teacher Su.
He didn't feel confident, and judging from his observations, Teacher Su didn't seem to have any problems.
"If not, let's leave first. It's a mess here. If anything happens, let's talk at school." Teacher Su said in a calm tone.
"Yeah, it's a mess here. When we get to school, there are plenty of opportunities to chat." Zhao Xuan followed.
"Okay...I'll send you off..."
Zhang Yu said this, but he looked at Teacher Su's heart and asked, "Did you kill him?"
"Yes!" Teacher Su's voice sounded in Zhang Yu's mind.
Zhang Yu's head buzzed when he heard this. He really didn't expect that he guessed it right this time.
However, there is a huge gap between Teacher Su's appearance and Fan Zhongping's description.
The person Fan Zhongping was talking about has not been found at all, but Teacher Su is the real murderer. What is the connection between the two?
Zhang Yu's mind was spinning rapidly, and he followed Teacher Su, Luo Xiang and the others as they walked out.
Seeing that he was approaching the door, Zhang Yu said: "Wait a minute!"
Teacher Su was the first to stop, but did not look back.
Luo Xiang turned around and said, "What's wrong?"
"I want to ask Teacher Su something." Zhang Yu said.
"What's the matter?" Seeing Zhang Yu mentioning himself, Teacher Su turned around.
Zhang Yu turned to look at Cao Dahua and said, "Sir Cao, could you please bring that bag over."
He is so good that he dared to let Cao Dahua take the package directly.
Cao Dahua naturally knew which bag it was. It could be said that when Zhang Yu was talking to Teacher Su, he was also staring at Teacher Su. Now that Zhang Yu said this, Cao Dahua immediately left with Ni Ni, Wu Xiangwang and the evidence.
past.
When he arrived, Zhang Yu pointed to the plastic bag Wu Xiangwang was carrying and said, "Teacher Su, have you seen this bag?"
Wu Xiangwang took out the bag from the plastic bag.
"I haven't seen it before." Teacher Su shook his head directly.
"Can you be sure after just one glance?" Zhang Yu asked.
"This is a man's bag. How can I recognize it? Of course I have never seen it." Teacher Su replied.
"It seems to be the same...but the outfit Teacher Su is wearing...seems a bit nondescript..." Zhang Yu said again.
