The police dogs can't find anything to gain, and at least there won't be anything like shredding corpses here recently.

However, Bai Song wanted to call the two dogs in Jiuhe District over and ask the dogs to confirm whether the smell here was the same as the smell of the sofa. It's just that even if the dog's judgment is consistent, it doesn't prove anything.

...

Leaving from this side basically means that the value of this lead is already low.

"Now you can only count the calculations, Zhang Zuo can't be alone, he must also have his circle and some of his subordinates. Da Hei was caught, and then immediately after Zhang Zuo was arrested, the grass startled the snake, and I dare not say whether the snake will be shocked, but there must be a lot of snake-related people who have been shocked. Bai Song said.

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

"We need a lot of information for big data analysis. Bai Song said: "We need information support from the Vehicle Management Office, the traffic police, the Market Supervision Administration, and the Food and Drug Administration." ”

"Rely on the three of us?" Liu Shuyuan said: "Here in Tianbei District, I can help a little." ”

"Don't do it behind closed doors, you see that we ran the warehouse here, and it collided with the Xingang Branch, people have already checked, we are in vain, I will call the Zhao detachment and share resources." Bai Song said.

"Hmph, I don't think he has any evidence, do I? If you want me to say, it's better to wait, tomorrow morning, he will have to take the initiative to find you. He summoned someone, I want to see what he will do in 24 hours!" Wang Liang was still a little angry.

"Now is not the time to gas. Bai Song shook his head.

"You have a good temper, if I definitely wouldn't do that, how can you be considered a leader, right?" Wang Liang said.

"It's not that I'm open-minded, it's that it doesn't have to. After speaking, he took out his mobile phone and dialed the phone.

...

"Captain Bai, what's the matter?" Detachment Zhao took more than ten seconds before picking up the phone.

"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 has something to say. ”

"We took a record for Zhuge Yong, that is, Wang Qianyi's former subordinate today, and obtained some clues, Zhuge Yong confessed that Zhang Zuo had purchased wild animals through him at least twice, although the transfer record did not have specific personal information, but there was the identification of the co-defendant, if you really can't do it there, you can also temporarily approve a seven-day criminal detention by relying on this. Bai Song first told the Zhao detachment the clues he got today.

A simple identification of a co-defendant cannot conclude the case, but if the Zhao detachment is more resolute, it can still be done just by taking criminal detention.

The Zhao detachment has already driven itself into a corner. According to the clues provided by Bai Song, forcibly approving a criminal detention can always make the case a lot more timely.

"Okay, thank you. The Zhao detachment said after a while: "I summoned him as a helpless move, Da Hei was arrested, and this Zhang Zuo is likely to be shocked." ”

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

After saying this, Bai Song was not very happy, he knew that this situation meant that the interrogation of the Zhao detachment did not obtain any valuable clues.

...

Then, Bai Song and the Zhao detachment did a real exchange of information on the case for the first time, and Bai Song's understanding of Zhang Zuo was still deeper after all, which was very helpful to the Zhao detachment's interrogation.

And the detachment here can help Bai Song even more.

Zhang Zuo was arrested today, but in fact, he didn't have much sense of defense. The people associated with him also had no specific precautions.

Now, it is already certain that Zhang Zuo's range of activities is in Tianbei District, and through the analysis of some clues from Zheng Xiaowu, Zheng Xiaowu took a taxi to Tianbei District that night.

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

The driver can only remember that he went to Tianbei District to see Zheng Xiaowu that day, but he can't remember the specific place.

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

However, not all places are so well monitored, and it is true that there is no place for the driver to park.

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

As an important chemical catalyst, carbon monoxide is also widely used.

...

Here Wang Liang and Liu Shuyuan's abilities are revealed.

Liu Shuyuan's interpersonal relationship does not only rely on his father, his own connections are very terrifying, which Bai Song admires incomparably.

At more than eleven o'clock in the evening, under the analysis of big data, the pharmaceutical factory was finally found.

This is precisely one of the pharmaceutical companies where Daikoku worked as a salesman before.

Many salesmen have had multiple job hopping records, and Dahei is no exception. He had worked here, but he wasn't the last one to work, so he didn't get much attention before.

Zhang Zuo's parents have nothing to do with this pharmaceutical company, which makes everyone excited and at the same time feel a little puzzled, how did Zhang Zuo get online?

In the evening of the same day, multiple departments worked together to conduct a surprise inspection of the pharmaceutical factory.

The inspection at night is better than the daytime, this place is not only a problem of illegal use of some chemicals, but even uses its own qualifications to illegally resell some chemical raw materials to some unqualified enterprises.

The company that dared to do this is supposed to be almost dead a long time ago, but this one still has some channels, so that when I went at night, I was caught.

...

Sometimes people don't push themselves, and they really don't know what the result will be.

The Zhao detachment suddenly summoned Zhang Zuo, but after the current energy cooperation, they still found the bare place of the clue.

Although Zhang Zuo is shrewd, he is always a rich second generation of dogs and horses, and it is impossible to be cautious and seamless forever.

...

Bai Song does not think that Zhang Zuo is the real murderer of Li, because he really has no motive for committing the crime, and Wang Ruoyi is the real murderer, which has also been verified by a lot of rigorous evidence.

But the relationship between Zhang Zuo and Wang Ruoyi will not be so simple, and he must have helped in dealing with Li's body and other things, and there may be other problems here.

Now, the pharmaceutical company has made great gains, even without Zhuge Yong's confession, Zhang Zuo can be criminally detained, and the rest has become simpler.
