The term said by the Qin detachment really touched the blind spot of Bai Song's knowledge.

The alkalinization hydrolysis method, which is mostly used in the international community to deal with poultry and livestock suffering from infectious diseases, can decompose animal tissues, fats, proteins and other substances into soluble polypeptide chains, fatty acids and liquid glycerol and other substances, which is very clean and clean.

But it's not so simple, not only the corresponding chemicals are needed, but also such a device needs to be maintained in a state of high temperature and high pressure for several hours to have an effect.

I won't go into details.

Only some bone fragments can be left, and all the rest can be discharged, and all the germs in the dead livestock will be killed, and no harmful gases will be produced.

...

The carcasses of animals and poultry treated in this way, let alone cells, cannot be found to have complete DNA.

After listening to the introduction of the Qin detachment, Bai Song and his friends were stunned.

Is there still such an operation?

"Can you get evidence of this?" someone asked.

"It's okay to say it on the night of the crime, but it's too difficult now. The Qin detachment said: "This laboratory has to be disinfected every day, and after more than ten days, the evidence on the scene has been lost a bit badly." However, it is still possible to extract some biological traces from the sewers. ”

After saying this, Qin Wushuang looked at Wang Liang: "You take two people to chase the monitor." ”

At the beginning, I only paid attention to Zheng Xiaowu's taxi, and the video did not retrieve more, but now I can check where Zhang Zuo went through the surveillance video.

If everyone is not mistaken, Zhang Zuo definitely threw away some of Dou Jianli's clothes, and the bone fragments that did not dissolve were buried by him in a possible safe place.

Wang Liang and the Qin detachment asked a few words again, took the two of them and set off.

Bai Song looked at Wang Liang's back and sighed with emotion. Since Bai Song left the third team, Wang Liang has been a detective of the third team, although he has been running around with Bai Song recently, he can be regarded as his own leader.

...

The tattooed man saw that all the police had checked and didn't find it, and he was also anxious, and he wanted to ask Bai Song about the progress several times, but there were a lot of people, and he never had a chance.

...

The method of alkalinization hydrolysis is too extreme, and it can only be found in the laboratory of this pharmaceutical factory, generally speaking, in a regular laboratory, any equipment and the like have a record of use, but this pharmaceutical factory has its own problems, Zhang Zuo can basically control it.

...

Tonight, nearly half of the detachment was dispatched, and six police dogs alone were dispatched.

The police dog is not a criminal police team, it belongs to the patrol special police detachment in the Jiuhe Branch, and it is basically all sent out today.

Not only here, but even the Jiang team sent people over to help.

The horn of the narwhal was indeed something, and it was put in the crack on the back of the big cabinet at home by Dou Jianli, and it had been taken away by the Jiang team and others.

Of course, this is normal, if it is so easy to see, Dou Jianli will not be unable to find out.

This should be the same as the 100,000 VND, using a special method to keep secrets, which needs to be handled by professional people.

In order to find Dou Jianli's bones, the Jiang team also provided a little technical support. In fact, the public security and the Jiang team should have the same equipment, but they each have their own special methods.

Wang Liang quickly chased the car from the video, and also found the general location of Zhang Zuo's exit, and contacted the taxi driver through the license plate number.

The clothes were thrown away by Zhang Zuo, this is really not to be chased, through the verification, as early as ten days ago was picked up by the sanitation workers, after N procedures, it is really unrealistic to find a few pieces of garbage.

However, these bones were not thrown away.

Wang Liang used the video from the camera to build a grid-like 3D model, and made an AI analysis of the place where Zhang Zuo might have buried the bones.

Because Zhang Zuo didn't go anywhere to be monitored, the results of AI analysis still had a large area, and the Qin detachment directly ordered a carpet investigation.

After a night of hard work, the last piece of the puzzle was finally found.

The bones were found to be the two dogs barking when they smelled the sofa.

At the burial site, Zhang Zuo's hair was also found.

...

The sky was already dark.

"Now, I want to see what kind of face that Zhao detachment has. Wang Liang said proudly with two dark circles under his eyes.

"Which Zhao detachment?" Bai Song asked.

"The one from the Newport Branch. ”

"Breath!" Bai Song snorted and turned away, his face full of smiles.

Now is the era of emphasizing evidence over confession, Zhang Zuo must not say anything, these people are engaged in this industry, they have received special training, but there is no problem with a few of them not saying it.

Now there is enough evidence to condemn Zhang Zuo's crime to death, and he will properly send a gun.

Ding Jianguo's crime is completely determined by the Jiang team, and this matter has nothing to do with Bai Song and others, but this is also a good thing, otherwise it will always feel weird.

Maybe that's why there is a recusal system.

Zhang Zuo's puzzle has been put together little by little, and the case that happened in the Xingang Branch has completely entered the end, and the only small problem is Zhang Che's matter.

Now Bai Song suspects that in Sun's suicide case, it was Zhang Che who went to find a relationship with Sun, so that the follow-up compensation was quickly in place. This does not mean that Zhang Che is kind enough to help Sun, Bai Song feels that this routine seems a little familiar.

It's like... It seems that Zhang Che tried to find a way to make Sun have to commit suicide.

Speaking of which, it is similar to Zhang Che's arrangement of Zhang Zuo in Zhang Shuyong's home back then.

It's not time to analyze this now, anyway, the people who should be arrested have been arrested, and Zhang Che has also been found out to have some other things, related to Team Jiang and others, and they will definitely not be able to get out.

...

It's time to rest.

Two cars from the Jiuhe Branch, one car from the Jiang team, drove to the Xingang Branch to escort Zhang Zuo.

In addition to them, another car also came, and the Tianbei Branch also wanted to take people away.

The murder case that was investigated all night last night was actually a case in their jurisdiction, and it was taken away by the Jiuhe Branch.

For this matter, the three sub-bureaus fought for a long time, and the Xingang sub-bureau was the weakest.

Although they arrested people, the cause of the case was not strong enough, and the Jiuhe Branch of the People's Republic of China was a homicide...

Team Jiang and others also want people, but they stand on the united front with the Jiuhe Branch, and it is the same wherever they put people, and it does not affect the ending.

Zhang Zuo may never have dreamed that after his details and what he did were revealed, so many units would rob him.
