Although the time was already early in the morning, after the interrogation of Yang Yuting and Zeng Cheng, Lin Jia and Ling Zhan and others did not have the slightest intention of leaving work, and all gathered in the office of the serious crime team, first exchanged the results of the interrogation with each other, and then started a heated discussion.

"Yang Wenjing's cloth doll was not given by Yang Yuting?"

There is also the kind of sanitary napkin from abroad that has been manipulated and tampered with by others, and it is not from Yang Yuting, which makes Ling Zhan and others very surprised.

"I feel that Yang Yuting should not be lying about these two things. ”

When everyone watched the image of the young man standing in front of the laboratory building of the University of Science and Technology chatting with Yang Wenjing for a while in the surveillance video from the laboratory building of the University of Science and Technology, and listened to the content of Song Jin's dialogue with Yang Wenjing in the English corner of the school after listening to Song Jin's copy from the BBS of the University of Science and Technology, two questions immediately rose in everyone's hearts.

Who is the young man who asked Yang Wenjing about Yang Yuting's situation?

Could it be the third person who appeared at the first scene of Yang Wenjing's murder?

What is certain is that it will never be the unknown person A that the Serious Crime Unit has been looking for. Because on the basis of the fourth possibility proposed by Ling Zhan, A and Yang Yuting belong to the same organization, or even Yang Yuting's upline, then he (she) does not need to inquire about Yang Yuting's situation at all.

In view of this, it is impossible for that mysterious young man to appear at the first scene of Yang Wenjing's murder, that is, the third person from Hu Yuan's family. The reason is also very simple, if A is the culprit behind the two criminal cases of Yang Wenjing and Yang Yutang, then the person who appeared at the scene of Yang Wenjing's murder, if not A, must be a person who has a close relationship with A, so naturally there is no need to deliberately inquire about Yang Yuting's situation.

Naturally, one of the next priorities is undoubtedly to find this mysterious young man who suddenly appeared next to Yang Wenjing as soon as possible.

"It's a pity that because Yang Yuting has always insisted that there is little contact with Yang Yutang, we still haven't been able to find the key person who lurked around Yang Yutang and was overlooked by us. ”

Hearing Song Jin's words, Lin Jia said confidently: "It is impossible for a spy with a high IQ like Yang Yuting to let him reveal everything he knows at one time. Especially when he decides to atone for his sins, he will not pour out his head like other criminals. ”

"The forest bureau is right, and with his performance, he must still have important clues that we are eager to know. I don't want to say it for the time being, but I naturally want to see our attitude next. ”

At Xun Jianguo's age, the veteran police officers who have worked in the public security system for decades have never seen any kind of criminal. Therefore, even if he has not studied psychology systematically, when he encounters Yang Yuting's performance tonight, he can see through his inner thoughts almost at a glance based on experience.

"Old comrade, according to what you mean, Yang Yuting intends to hang our appetite like squeezing toothpaste?"

"Not really. But without figuring out how many years his sentence can be reduced after figuring out what he knows, he shouldn't be able to tell it all happily. ”

"You can't find a judge to sentence him thoroughly, right?"

knew that Jia Wei was complaining, so Xun Jianguo didn't talk anymore. Surprisingly, Rong Liang, who has always been used to getting along with Jia Wei, also did not answer.

"What is unbelievable is that the forest bureau, the Ling team. Xiao Hua interjected at this time: "If our investigation direction is correct, then whether it is the unknown person A or Li Diying, they actually made a very coincidental move at the same time - throwing Mu Qixiong as a cover. ”

"It's true that it's just a coincidence yet, and although we haven't found him or her yet, his identity is relatively clear. However, Li Diying's identity has yet to be further determined. As long as Li Diying's identity is determined, this problem will be solved. What is certain now is that Li Diying and A should not belong to the same camp. ”

Knowing that everyone already knew about the spy organization that appeared in General City and surrounded the Dongfeng Coating Factory, Ling Zhan didn't cover it up too much when answering Xiao Hua's question.

"Team Ling, the third person who appeared at the scene of Zhou Wei's car accident, should have a certain connection with the electromagnetic wave signal that Cui Luyi and Zhang Chunhe found in Labor Park the day before yesterday. Today I have arranged for someone to track down the radio that has been tampered with. ”

Hearing Lin Jia say this, Ling Zhan spoke: "Then let's go both ways, and go back to our side to track down the person who gave Wu Jian the signal at the scene of Zhou Wei's car accident." Saying that, Ling Zhan turned his head to look at Jia Wei and Zhao Zengyuan and ordered, "Let Jia Wei and Zengyuan be responsible." ”

"Team Ling, where is Du Xiaowei?"

"Adjust it, Du Xiaowei will hand it over to Xiao Hua for the time being. As for the investigation of Yang Wenjing's interpersonal relationship, it will be postponed for the time being, and we will wait until we find out this mysterious young man first. ”

At this point, the focus of the next work was gradually clear, and Ling Zhan arranged the division of labor among the members of the serious crime team in front of Lin Jia.

Rong Liang was responsible for investigating the clues of the depositors in the bank safe according to Zeng Cheng's confession, focusing on the bank's monitoring, as well as the monitoring of Feiying Express and the courier. Mu Qixiong, I'll arrange for someone to replace you.

Song Jin temporarily handed over the work of monitoring Li Diying to the police station in the jurisdiction, and if necessary, he could also transfer people from the criminal police team in the bureau. Next, you and Qi Zhibin focus on tracking down the young man who appeared next to Yang Wenjing. Then compare the antique files that Jia Wei took from Zhou Wei's wife to see if this mysterious young man can be in them.

Uncle Xun and I were in charge of finding Wang Jianxun, the bank security guard who had been bought by Zeng Cheng and had resigned, and continued to interrogate Zeng Cheng. ”

As soon as Ling Zhan's words fell, Lin Jia said, "Team Ling, investigate the young man who appeared next to Yang Wenjing, and I will arrange another person to cooperate with you." Then he turned his head to Song Jin and said, "Song Jin knows what to do." ”

"Yes, Forest Bureau. ”

Knowing that Lin Jia was inconvenient to say more in front of too many people, Ling Zhan didn't ask more.

"Also, when we leave in a while, we will take Yang Yuting away together, and if there are new clues, I will notify Team Ling as soon as possible. Looking at Ling Zhan, Lin Jia said, "Either I'll get here first tonight, it's not too early, let's go back and rest well." ”

"Okay, let's stop here. ”

It's close to two o'clock in the morning, and if you don't go back to rest after work, it will definitely affect the work efficiency of the next day.

Just helped send Yang Yuting to the police car driven by the National Security Bureau, and Ling Zhan, who was not sleepy, returned to the office alone. Poured a glass of water, sat on the chair and closed his eyes slightly, recalling and sorting out the interrogation of Zeng Cheng at night and the discussion process just now in his mind.

Zeng Cheng said that after buying off Wang Jianxun, a bank security guard, the young woman who went to deposit money in the safe that he saw through the bank's monitoring was not necessarily the person who hired him, maybe just an errand runner.

Also, Yang Yuting confessed, is the young man who appeared next to Yang Wenjing really unrelated to the unknown person?

He has always liked to think backwards and is good at considering problems from different standpoints, and has solved many big and important cases, which is one of the main reasons why Ling Zhan was called a criminal investigation expert by his peers at a young age.

Therefore, when Ling Zhan habitually raised the above two doubts again, he couldn't help but fall into a long period of deep thought.

Regarding the first suspicion, the more Ling Zhan thought about it, the more he felt that it was very unlikely that he would hire Zeng Cheng's people to save money in person.

First of all, anyone who knows a little common sense knows that there is high-definition surveillance inside and outside the bank, let alone a spy who has undergone long-term training, how can he take such a big risk.

Secondly, in order not to make his move of carrying a large bag of RMB too noticeable, according to Zeng Cheng's confession, he received US dollars several times. In other words, the two people before and after paying him must be able to raise a large amount of dollar cash.

This is not something that any single person can do under the reality that the state is very strict about foreign exchange management. So is it possible to start from this aspect and investigate the people who have exchanged a large amount of foreign exchange in the recent period, will we find out the clues of the people who hired Zeng Cheng behind the scenes?

Thinking of this, the name "Yang Yutang" immediately popped up in Ling Zhan's mind. Yang Yutang, who has five years of experience in money laundering, is indeed in a position to use a large amount of US dollar cash at any time. Assuming that the remuneration paid to Zeng Cheng on the three occasions before and after was all from Yang Yutang, then it is necessary to find evidence that Yang Yutang not only obeyed A's orders, but also served other organizations, such as those who hired Zeng Cheng.

The reason why Ling Zhan made such an assumption was because Yang Yutang was a businessman after all, and there was not the slightest evidence that Yang Yutang was a member of the organization to which the unknown person A belonged.

Continuing to analyze along this line of thought, if the person who hired Zeng Cheng really received a large amount of US dollars in cash from Yang Yutang, then it is entirely possible to logically ask Yang Yutang to send someone to deposit the money in the designated bank safe. In this way, the young woman Zeng Cheng saw in the bank surveillance must be the person next to Yang Yutang, who knows his secrets and often runs errands for him.

At this point, Ling Zhan immediately had such a question in his heart - could this person who ran errands for Yang Yutang be the key person who was neglected in the assassination of Yang Yutang that the serious crime team had been looking for?

With a height of about one meter and six five, a weight of less than sixty kilograms, a slender figure, and fair and delicate skin. Combined with Zeng Cheng's description, a clear appearance of a person gradually appeared in Ling Zhan's mind - Du Xiaowei, Yang Yutang's secretary.

However, Ling Zhan immediately denied his idea. Because according to the current indications, if Du Xiaowei has a problem, it can only be someone on the line of unknown person A. It is very unlikely that he was involved in the death of Zhou Wei in a car accident.

Regarding the second doubt, Ling Zhan is not without reason.

In Yang Wenjing's case, A used the strategy of "leaving a disaster in Jiangdong" - deliberately throwing out the bank card of Zhou Wei, who died in a car accident, to shift the police's attention to Mu Qixiong's line, that is, to appear on another overseas spy organization in Jiangjuncheng. Not only can he use the hands of the police to eliminate a competitor, but he can also eliminate the threat to him or her from someone on Mu Qixiong's line.

If the young man who appeared next to Yang Wenjing was also deliberately arranged by A, then what was his (her) purpose this time?

Could it be that he wants to use the young man who appeared next to Yang Wenjing to deliberately inquire about Yang Yuting's news, and create a false impression for the police that the young man does not belong to the same camp as Yang Yuting, or A, so as to blame other spy organizations for the suspicion of killing Yang Wenjing?

Ling Zhan knew in his heart that if he wanted to solve the two doubts he had raised with reverse thinking, he must first find Wang Jianxun, a bank security guard who had resigned, and the mysterious young man who appeared next to Yang Wenjing.

Seeing that the time was already three o'clock in the morning, Ling Zhan raised his hand and rubbed his temples, took a glass of water and drank two sips, and then got up to rest in the dormitory.
