Bai Song read the case file all night yesterday.

When he came back last night, he left himself in the conference room.

In the past two or three days, there are not many case files gathered here, including the bank's flow information, Bai Song only took two or three hours to read all the case files, but for the next case, there is still no useful progress.

"White team, it's still busy. A local criminal policeman entered the conference room and saw Bai Song still sitting here: "I see that they all went to the cafeteria to chat." ”

"They are all elders, and they don't know each other very well. Bai Song raised his head: "Master Zhang, what do you have in your hand?"

"Oh, the social relationship map of these people", Officer Zhang pointed to the case file on the table: "Photocopy, there is a copy on the table." ”

Originally, Bai Song was still a little excited, but when he heard this, he said: "Well, Master Zhang, you can put it here first, and I'll clean up the case file." ”

"Captain Bai, your work attitude is really embarrassing, don't look at me as many years older than you, but I have to learn more from you in this regard. Master Zhang deliberately accosted.

"Master Zhang, don't say that, I'm a stupid bird flying first, I don't have any big skills, I can only rely on time to pile up. ”

"Hahaha, you're humble. Officer Zhang thought for a while and said, "By the way, I have an eldest sister who is in your Jiuhe District, and in the future, we may have a chance to meet again." ”

"There's definitely a chance. Bai Song smiled.

"Okay, okay, there's a chance to sit. Master Zhang continued: "Speaking of which, my sister's son used to be an auxiliary police officer at the Jiuheqiao Police Station over there, and later resigned in the unit and was promoted, and it is estimated that he will graduate and take the police exam next year. ”

Only then did Bai Song understand that Master Zhang's purpose was to pull the relationship, which was also human nature, but when Master Zhang said this, Bai Song suddenly thought of something: "Your nephew's name is Chu Sanmi?"

"Yes, yes, yes", Officer Zhang was very happy: "You actually know him?"

"Well, when I first joined the work, Sanmi and I were at a police station, and he followed me to the police, and we had a good relationship. Bai Song was also a little happy, and he still felt inexplicably warm when he heard this name.

"Ah, such a coincidence, that's my redundancy, okay, then you can take care of it more then", Master Zhang said: "If he can be admitted next year, I will take him to Xingang District, train him well for a few months, and then let him go back to work in Jiuhe District, I can't embarrass you, right?"

Master Zhang directly threw his nephew into the faction of Bai Song.

"That's not a problem. Bai Song smiled.

...

This is the case for all the elders, Bai Song also said why Master Zhang came to chat with him, and after a long time, this is actually Sanmi's uncle.

Although Bai Song's level is not high, such a young associate department is definitely a thigh for Master Zhang's nephew, so he wanted to come in and give his nephew a relationship, but he didn't expect to know each other, which is of course better.

However, the mention of Sanmi reminded Bai Song of the time when he and Sanmi handled the case together.

This lad, well... Cute and fun...

Well, no, diligent and studious!

Walking in his mind, Bai Song looked at the relationship chart that Lao Zhang brought over, a copy, and was a little distracted.

Wait, this one is a little familiar???

Every time Bai Song finds something familiar, he will gain a little more or less, but many things are buried too deep in the long river of memory and can't be remembered at all.

However, at this time, because he thought about Sanmi, thought of the case at that time, and looked at the relationship diagram again, Bai Song recognized a person at once.

This person was one of the people related to Li in the first murder case, the case of Li's body being crushed. (Note: Chapter 21 of this book)

At the beginning, in order to find out the situation of Li, a total of 11 people were summoned to the criminal police detachment, in addition to Wang Qianyi and the landlord and others, there was another person, who was the chief surgeon of the plastic surgery hospital at that time, who was 30 years old at the time, this person was a returnee graduate student, very handsome, and left a deep impression on Bai Song.

However, he simply investigated at that time, so he had no motive for committing the crime, and what happened later had nothing to do with him, so he didn't continue to consider this person.

And now, Bai Song saw this person again.

Zheng Xiaowu asked him for plastic surgery.

It's not that this person will be suspicious, but after all, Tianhua City has a population of more than 10 million, there are so many plastic surgery hospitals, and it is not so easy for two people to meet the same doctor.

Moreover, the doctor's fee is not low, Zheng Xiaowu is just a hyaluronic acid, and he has not yet gone under the knife, why did he go to Jiuhe District to do it?

Once this memory was dug up, Bai Song began to quickly diverge his thoughts.

The first possibility is accidental.

As a plastic surgeon, this person has done plastic surgery or injections and other surgeries on countless people, Li and Zheng Xiaowu are both people with plastic surgery needs, and it is understandable to look for him.

The second possibility is that there are commonalities.

In other words, Zheng Xiaowu and Li may have mutual friends, and then this friend introduced them to the same plastic surgeon.

The first possibility is to be ruled out for the time being.

If they both had mutual friends, who would they be?

Zheng Xiaowu only got hyaluronic acid recently, and it must have nothing to do with Wang Qianyi and Wang Ruoyi, so who could it be?

Gathering all the possibilities in his mind, Bai Song suddenly thought of someone.

Zhang Zuo. The rich second generation who likes Wang Ruoyi.

At that time, Wang Ruoyi was arrested for intentional homicide, and Zhang Zuo was also guilty of harboring and was sentenced to a one-year suspended sentence.

Bai Song didn't pay much attention to this case at that time, he went home to play after the case was over, and when he came back, he went to the police station to handle the case every day, and the follow-up work was also done by the criminal police team. When I paid attention to the case again, I basically just focused on Wang Ruoyi and Wang Qianyi, why do you want so many supporting roles?

But now, Bai Song seems to have figured out something.

If it is said that Li and Zheng Xiaowu are both related to one person, this person may be Zhang Zuo, this rich second generation is a typical womanizer, and Zheng Xiaowu is indeed beautiful.

Zhang Zuo knows the beautiful local anchors in Tianhua City, which is indeed too normal.

And digging Zhang Zuo out of the depths of his mind, Bai Song began to recall the scenes of this person again.

Wrong!!!

Bai Song suddenly thought!

When he was in the Economic Investigation Corps before, when he and Liu Shuyuan went to the health hospital and other places together, he passed by Zhang Zuo's warehouse once.

At that time, Bai Song still remembered in his mind that this warehouse had not changed at all.

How could it be that nothing has changed?!

It stands to reason that Zhang Zuo knows that this is the site of the corpse, and he will definitely not continue to rent!

In that case, the new tenant will definitely change the locks, right?

Why hasn't it changed at all, and the locks haven't changed?

That's not right!

Zhang Zuo, there is a problem!
