Police Detective

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

The alkaline hydrolysis method is often used internationally to treat poultry and livestock suffering from infectious diseases. It can decompose animal tissues, fats, proteins and other substances into soluble polypeptide chains, fatty acids, liquid glycerol and other substances, which is very clean.

But it is not that simple. It not only requires corresponding chemicals, but also requires such a device, which must maintain high temperature and high pressure for several hours to be effective.

I won’t go into details.

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

…

From the carcasses of animals and poultry treated in this way, not to mention cells, DNA cannot be found intact.

Bai Song and his friends were shocked after hearing the introduction from Qin detachment.

Is there still such an operation?

"Can this be evidenced?" someone asked.

"If it was okay on the night of the crime, it's too difficult now." Detachment Qin said: "This laboratory has to be disinfected every day. After more than ten days, the evidence on the scene has been somewhat destroyed. However, it is still possible to extract some from the sewer. Biological traces.”

After saying this, Qin Wushuang looked at Wang Liang: "Take two people and go after the surveillance camera."

At first, we only paid attention to Zheng Xiaowu's taxi situation, and did not retrieve more videos later. Now we can use the surveillance video to find out where Zhang Zuo went.

If everyone guessed correctly, Zhang Zuo must have thrown away some of Dou Jianli's clothes and buried the undissolved bone fragments in a possibly safe place.

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

Bai Song looked at Wang Liang's back with some emotion. Since Bai Song left the Third Team, Wang Liang has become a detective of the Third Team. Although he has followed Bai Song everywhere recently, he can still be regarded as his own.

The tattooed man saw that all the police officers had checked and found nothing. He was anxious and wanted to ask Bai Song several times about the progress, but there were too many people and he never had the chance.

The alkaline hydrolysis method is too extreme, and can only be found in laboratories of pharmaceutical companies. Generally speaking, regular laboratories have usage records for any equipment, but this pharmaceutical factory itself has There is a problem, and Zhang Zuo can basically control it.

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

The police dogs are not from the criminal police team. They are part of the special patrol detachment in Jiuhe branch. Basically, they are all dispatched today.

Not just here, but Team Jiang also sent people over to help.

The narwhal's horn was indeed real. It was placed by Dou Jianli in the gap on the back of the big cabinet at home. It had been taken away by Captain Jiang and others. Bai Song saw this half of the horn, but he didn't look at anything. come out.

Of course, this is normal. If it was so easy to see, Dou Jianli wouldn't be able to detect it.

This should be the same as the 100,000 VND. Special methods were used to keep the secrets secret, and it requires professional people to handle it.

In order to find Dou Jianli's bones, Team Jiang also provided some technical support. In fact, the police and Captain Jiang have the same equipment, but each has its own special methods.

Wang Liang quickly tracked the car from the video, found the general location where Zhang Zuo got off, and contacted the taxi driver through the license plate number.

The clothes were thrown away by Zhang Zuo. It was really impossible to trace them. After verification, it was found that they had been picked up by sanitation workers ten days ago. After going through N procedures, it was really unrealistic to find a few pieces of garbage.

However, these bones were not thrown away.

Wang Liang used the camera video to build a grid-like three-dimensional model and conducted an AI analysis on the places where Zhang Zuo might have buried his bones.

Because Zhang Zuo was not monitored everywhere he went, the results of the AI ​​analysis still covered a large area, so the Qin detachment directly ordered a blanket investigation.

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

The ones who discovered the buried bones were the two dogs that barked when they sniffed the sofa.

Zhang Zuo’s lost hair was also found at the burial site.

It's already dawn.

"Now, I want to see what detachment Zhao's face looks like." Wang Liang said proudly with two dark circles under his eyes.

"Which Zhao detachment?" Bai Song asked.

"The one from the Xingang branch."

"Come on!" Bai Song snorted and turned around with a smile on his face.

Now is an era where evidence is valued over confessions. Zhang Zuo must have said nothing. These people are engaged in this industry and have received special training, but there is no problem if a few of them do not say anything.

Now there is enough evidence to convict Zhang Zuo and give him a gun.

Ding Jianguo's crime depends entirely on Captain Jiang and the others. This matter has nothing to do with Bai Song and others, but this is also a good thing, otherwise it would always feel weird.

Maybe that's why there are avoidance systems.

Zhang Zuo's jigsaw puzzle has been pieced together bit by bit, and the case that occurred in Xingang Branch has completely come to an end. 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 connection for Sun, so that subsequent compensation could be quickly paid. This does not mean that Zhang Che is helping Sun out of kindness. Bai Song feels that this routine seems a bit familiar.

This feeling was as if Zhang Che was trying to find a way to force Sun to commit suicide.

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

Now is not the time to analyze this. Anyway, everyone who should be arrested has been arrested. Zhang Che has also been found out about some other things, which are related to Captain Jiang and others. He will definitely not be able to get out.

It's time to take a break.

Two vehicles from Jiuhe Branch and one from Captain Jiang drove to Xingang Branch to escort Zhang Zuo.

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

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

The three branches have been fighting for a long time over this matter, and among them, the Xingang branch has the weakest voice.

Although they arrested someone, the case was not strong enough. The Jiuhe Branch took action and it was a murder case.

Captain Jiang and others also wanted people, but they stood on a united front with the Jiuhe Branch. It didn't matter where they were placed, and it didn't affect the outcome.

Zhang Zuo probably never dreamed that so many units would rob him after his details and what he had done were revealed.
