Police Detective

Even the police dogs couldn't find anything. At least there won't be anything like mutilated corpses here recently.

However, Bai Song wanted to call two dogs from Jiuhe District over and ask the dogs to confirm whether the smell here was consistent with that of the sofa. But even if the dogs are unanimous in their judgment, it doesn't prove anything.

…

Leaving from here basically means that the value of this clue has been very low.

"Now we can only resort to tricks. Zhang Zuo cannot be alone. He must also have his circle and some of his subordinates. Dahei was arrested, and then Zhang Zuo was arrested. To scare the snake, what will the "snake" do? I don’t dare to say that I’m not scared, but many people related to snakes must have been scared.” Bai Song said.

"So, what do you want to say?" Wang Liang said.

"We need massive amounts of information for big data analysis." Bai Song said: "We need information support from the Vehicle Management Office, traffic police, market supervision administration, and Food and Drug Administration."

"It depends on the three of us?" Liu Shuyuan said, "I can help a little bit here in Tianbei District."

"Stop working behind closed doors. You see, when we went to the warehouse here, we collided with the Xingang branch. They have already checked it out. We are here in vain. I will call the Zhao detachment and share resources." Bai Song said.

"Hmph, I don't think he has any evidence, right? If you ask me, it's better to wait. He will definitely come to you tomorrow morning. He has summoned someone, but I want to see what he will do in 24 hours. !" Wang Liang was still a little angry.

"Now is not the time to vent your anger." Bai Song shook his head.

"You have a good temper. If I were the one, I definitely wouldn't let it go like this. You are considered a leader after all, right?" Wang Liang said.

"It's not that I'm open-minded, but it's not necessary." After saying that, he took out his mobile phone and dialed the number.

…

"Captain Bai, what's the matter?" Detachment Zhao answered the call after more than ten seconds.

"Are you still busy with the interrogation over there?" Bai Song asked.

"Not busy." Detachment Zhao understood that Bai Song already knew that he had summoned Zhang Zuo: "Captain Bai will speak directly if he has anything to say."

"Today we took transcripts from Zhuge Yong, Wang Qianyi's former subordinate, and got some clues. Zhuge Yong confessed that Zhang Zuo had purchased wild animals at least twice through him. Although the transfer records did not contain specific personal information, With the identification of the co-defendant, if you really have no choice, you can temporarily grant a seven-day criminal detention based on this." Bai Song first told the Zhao detachment the clues he obtained today.

A simple identification of a co-defendant cannot resolve the case, but if Zhao's detachment is more resolute, criminal detention can still be carried out.

Detachment Zhao has pushed himself into a dead end. According to the clue provided by Bai Song, forcibly approving criminal detention will give a lot of time to handle the case.

"Okay, thank you." Detachment Zhao said after a while: "I had no choice but to summon him. Dahei was arrested, and Zhang Zuo may have been shocked."

Bai Song didn't comment on this, but he knew that if a leader like Zhao detachment was willing to say this, even if he explained it to him, it would give both parties a step down. He didn't have any holidays with Detachment Zhao, so he said: "Detachment Zhao, you are really a responsible leader."

After saying this, Bai Song was not very happy. He knew that this situation meant that Zhao detachment's interrogation did not obtain any valuable clues.

…

Then, Bai Song and the Zhao detachment had a real exchange of information about the case for the first time. After all, Bai Song had a deeper understanding of Zhang Zuo, which was very helpful for the Zhao detachment's interrogation.

And the help the detachment here can give Bai Song is even greater.

Zhang Zuo was arrested today. In fact, he didn't have much sense of defense. People related to him have no specific precautions.

Now, it is certain that Zhang Zuo's activity range is mainly in Tianbei District, and through some clue analysis of Zheng Xiaowu, Zheng Xiaowu took a taxi to Tianbei District that night.

Through video surveillance, Zhao detachment and others found a taxi that Zheng Xiaowu had taken before.

The driver could only remember that he had gone to Tianbei District to see Zheng Xiaowu off that day, but he could not remember the specific place.

If it weren't for Zheng Xiaowu's outstanding appearance and the long distance, the driver wouldn't even be able to remember this.

However, not all places are so well monitored, and it is indeed impossible to find a place for drivers to park.

There are not many factories in Tianbei District that have demand for ether, and places that also need carbon monoxide can basically be checked one by one.

As an important chemical catalyst, carbon monoxide has a wide range of uses.

…

Here the abilities of Wang Liang and Liu Shuyuan are revealed.

Liu Shuyuan's interpersonal relationships are not only based on his father, but his own personal connections are very terrifying, which Bai Song admires very much.

At around 11 o'clock in the evening, through big data analysis, we finally found this pharmaceutical factory.

This happened to be one of the pharmaceutical factories where Dahei worked as a salesman.

Many salesmen have records of job-hopping many times, and Dahei is no exception. He also worked here before, but it was not the last one he worked for, so he didn't attract much attention before.

Zhang Zuo's parents had nothing to do with this pharmaceutical company. This made everyone excited but also felt a little confused. How did Zhang Zuo get connected?

That night, multiple departments collaborated to conduct a surprise inspection of the pharmaceutical factory.

Inspections at night are even more effective than during the day. This place is no longer just a problem with the illegal use of some chemicals. It even uses its own qualifications to illegally resell some chemical raw materials to some unqualified companies.

Any company that dared to do this would have been dead long ago, but this company still had some channels, so much so that when I went there at night, I was caught red-handed.

…

Sometimes people really don’t know what the results will be if they don’t push themselves.

The Zhao detachment suddenly summoned Zhang Zuo, but after working together now, they still found the clues.

Although Zhang Zuo is shrewd, he is still a sensual rich second generation. He cannot always be careful and flawless. Now that this flaw has been revealed, the rest will be simple.

…

Bai Song did not believe that Zhang Zuo was the real culprit who killed Li, because he did not have a motive for the crime. Wang Ruoyi's fact that he was the real culprit was verified by a lot of rigorous evidence.

But the relationship between Zhang Zuo and Wang Ruoyi is not that simple. He must have helped with matters such as handling Li's body. There may be other problems here.

Now, the pharmaceutical factory has achieved great results. Even without Zhuge Yong's confession, Zhang Zuo can be criminally detained, and the rest becomes simple.
