Qin Yong seemed to agree with Ren Qiang's words.

After listening, he nodded frequently.

Although there are still many uncertainties in the development of the case, the basic context is clear.

Whether Zhao Wenjun killed or not, logical reasoning cannot be used as evidence.

At present, the most important thing is to investigate the relationship between Wu Rui and Chen Lili, and whether Wu Rui can be found as soon as possible.

A month ago, Wu Rui resigned from Zhao Wenjun's company, and blood stains of the same blood type as Wu Rui were found in the trunk of the car he once drove.

All this makes everyone have a bad premonition.

It was Sun Jun's first action group and Ren Qiang's second action group that were busy.

But the current survey is not idle this time, Zhao Wenjun's car still has to be inspected.

Fortunately, the most troublesome trace evidence collection link has been completed, and Lu Chuan's main work is now in the laboratory.

The biggest difference between the analysis of trace physical evidence and the general collection and analysis of physical evidence is the fineness.

In the general identification and analysis of physical evidence, relatively speaking, the sample materials are relatively sufficient, and the fineness of the experimental instruments is lower.

However, the identification and analysis of trace physical evidence is often aimed at physical evidence weighing several grams.

With such a small number of samples, it is not even enough to contaminate the reagent in the general physical evidence identification analysis.

Therefore, the identification and analysis of trace physical evidence relies heavily on optical instruments.

On the contrary, chemical identification is rarely used.

Haizhou Normal University.

"Wu Rui studied applied chemistry education and graduated in June last year."

Wu Rui's counselor when he was in school was named Wang Min, and he was a master's student at Haizhou Normal University.

Zhang Hui was in charge of investigating some of Wu Rui and Chen Lili's situation at school.

Zhang Xiao and another group of people had already rushed to their homes to understand the situation.

"How is Wu Rui doing in the class? Have you been in touch with the school after graduation? Does he have a girlfriend?"

"Wu Rui's academic performance is average, and he originally wanted to go to graduate school, but he is not qualified to guarantee graduate school, and he has not been admitted to the graduate school entrance examination.

"After graduating, we tracked the employment prospects of our graduates, and at the end of last year, I called all of them...... Wait a minute, I'll look for the record sheet from that time......

"Well, here, Wu Rui said that he works in a private company and engages in ...... PR, but I didn't say which company."

"He didn't seem to have a girlfriend when he was in college, but I can guarantee that, but you can ask his roommate, there is a man named Sun Biao, who is a graduate student at school, and they had the best relationship at that time."

Grape Corridor of Haizhou Normal University.

"Officer Zhang, this is Sun Biao, Wu Rui's dormitory classmate, then you can talk about it, call me if you have something."

Zhang Hui nodded, thanked Wang Min, and looked at Sun Biao, who was a little nervous.

"Hello Sun Biao, my name is Zhang Hui, I am from the Criminal Investigation Detachment of the Municipal Bureau, and I want to learn about Wu Rui's situation with you."

"Zhang ...... Officer Zhang...... Lao Wu ...... Wu...... Wu Rui is not ...... What's going on...... What's wrong?"

Sun Biao is not stupid, suddenly someone from the Public Security Bureau came to him to understand Wu Rui's situation, then something must have happened to the other party.

"It's not clear for the time being, now Wu Rui is just missing, and it's not sure what happened to him."

Zhang Hui paused: "So, classmate Sun Biao, the situation I learned from you today is very important, and I hope you can actively cooperate and help us find Wu Rui one day earlier."

"Ah! Mmmm, don't worry, I'll cooperate well."

"When was the last time you saw Wu Rui?"

"February 19th."

Sun Biao did not hesitate at all, and said very accurately the last time the two met.

Zhang Hui's expression paused slightly.

On the 19th of last month, it has been more than a month now, nearly two months.

Even if Sun Biao has a good relationship with Ru Wu Rui, too

You don't remember it so clearly, do you?

Most people should say February, at most there is an approximate time of mid or late February.

How did Sun Biao remember it so clearly?

"Classmate Sun Biao, no wonder you can keep research, it seems that you have a good memory, and you remember the time so clearly."

"Oh, it's not that I have a good memory, our graduate students have a short winter vacation, and I will go back to school to practice a few days after the New Year."

"February 19th was my birthday, so I remember it very clearly, and Wu Rui invited me to a meal at the Ocean Restaurant."

Birthday?

No wonder.

But......

"You mean the Ocean Restaurant on Women's and Children's Road?"

"Yes, it's the Ocean Restaurant, Wu Rui also drove an Accord sedan to pick me up from school."

Ocean Restaurant is also a very famous restaurant in Haizhou City.

The main ingredient is seafood, but the price is relatively expensive, and I heard that the average per capita consumption is thousands of yuan.

Wu Rui went to such an expensive restaurant with Wu Biao.

As far as the information is known, Wu Rui's parents live in a rural area of a county under the jurisdiction of Haizhou City, and their living conditions are average.

Sun Biao said, and took out his mobile phone: "This mobile phone is also a birthday gift from Lao Wu, 10,000."

Zhang Hui took a look, the latest love crazy 16.

"He invited you to such an expensive meal, and gave you a mobile phone of more than 10,000 yuan, it seems that your relationship is indeed good."

Sun Biao nodded: "The relationship between the two of us is really good, his family conditions are average, when he was a sophomore, his father was sick and hospitalized due to lack of money, so I lent him the 100,000 yuan of New Year's money I praised since I was a child."

"Back then, it was considered to have saved his father's life."

"Did Wu Rui pay back the money later?"

"I paid it back, at the end of December last year."

"I asked him what kind of job he was looking for, but he didn't elaborate, just said that he was working in public relations at a fruit company."

"I've made a few big orders for the boss, and I also gave the car, and I picked up my Accord last time."

100,000 debts, 10,000 yuan of mobile phones, and thousands of yuan of food per capita... net

Zhang Hui recorded them one by one, and then asked.

"Does Wu Rui have a girlfriend?"

Faced with Zhang Hui's question, Sun Biao was unexpectedly stunned.

After a while, he said with some uncertainty, "It should be...... No, I don't."

Should there be?

What should be not.

"Classmate Sun Biao, you have such a good relationship with Wu Rui, why are you so unsure whether he has a girlfriend?"

"Well, it's not uncertain, he really didn't have a girlfriend when he was in college, he just had a crush on a girl in the math department."

"When he graduated, he seemed to confess to that girl, and then the two of them said that they would take the public exam together."

"But when I asked him later, he either didn't say anything, or he changed the subject, not saying that he had a girlfriend, nor did he say that he didn't have a girlfriend."

Sun Biao spread his hands: "So I didn't ask later, and he never said."

"What's the name of the girl he has a crush on?"

"My surname is Chen, and my name is Chen Lili."
