"But why do we only find small doses of N-dimethylnitrosamine and red powder in the water cooler?

"I analyzed that this is inseparable from the mastermind, and the stolen problem water is the key. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ”

"I analyzed that after the mastermind knew about the murderer, he immediately asked the housekeeper to remove the N-dimethylnitrosamine and add red powder. ”

As soon as Di Qi finished speaking, Xiang Junqing immediately yelled at everyone.

"Did you find N-dimethylnitrosamines in the warden's dormitory?"

"Yes! A small vial of clear crystals in a glass bottle was found. ”

Said a police officer involved in cleaning up the scene of the shooting in the warden.

"When I got it, I handed it over to the appraisal team along with other items. ”

"There should be this report in the results......"

As he spoke, the officer began to flip through the report.

In the conference room, only the sound of people turning the pages of the report could be heard.

"Here!"

When a police officer finds it, he immediately puts the report into the device. The content of the report is maximized.

In the center of the conference room, a report image is projected from the desktop.

"The results clearly state that the composition of the crystals is N-dimethylnitrosamine. ”

Di Qi said after a quick glance. Everyone also saw it, and nodded when they heard it.

This confirms that my analysis is not wrong. The housekeeper was manipulated by the mastermind to steal the chemical drug N-dimethylnitrosamine that killed the Indian and British male murderer. ”

While stealing N-dimethylnitrosamine, the warden, at the master's beheed, poured the red powder into the water dispenser. This is the same as pouring red powder into a police car. ”

"I analyzed that the mastermind would have such a move, just to make Yin Yingnan look like he died of natural causes. The cause of death and the murderer could not be found. ”

"Here, we bring the case back to the case of the death of a resident of the marginal area. We can see from the surveillance video that the warden hurriedly dumped two bottles of chemical drugs into the police car. ”

"I don't think that's what the mastermind expected. The mastermind poured red powder, purely as a warning. But he didn't want to be poured N-dimethylnitrosamine at the same time, and accidentally killed the residents of the marginal area. ”

The warden's mistake attracted the attention of the city government in the marginal district, and put pressure on Xiang Junqing. ”

"The mastermind had to take the risk of stealing the problem water that had been sent to the identification team. ”

"The problem water can only prove the poisoning and murder of Yin Yingmen, and cannot prove anything else. ”

"There is no point in the mastermind stealing the problem water!"

When Di Qi said this, Xiang Junqing immediately asked a question.

He felt that it was a shame for him that people were able to enter and leave the police station freely.

Therefore, he deliberately embarrassed him.

"The water in question proves that Yin Yingnan did not die of drinking water poisoning. Then there are many possibilities for Yin Yingnan's death. ”

"The mastermind stole the problem water, and the death of Yin Yingnan can be blamed on drinking water poisoning. The murderer of the case pointed to the person who poisoned him. ”

"When did the mastermind enter the police station?"

"I don't think the mastermind can enter and leave the police station freely!"

Xiang Junqing said solemnly, he put his hands around his chest, and he looked like he wanted Di Qi to speak clearly.

"When the first team went to the warden's dormitory, they had a problem with their mental state. This means that the mastermind knew that sooner or later the warden would attract the attention of the police. ”

The mastermind therefore decided to plot to kill the warden and steal the problem water as well. ”

"The officers of the second squad went crazy and smashed things, and the mastermind entered the police station according to the planned time of the police attack, and stole the problem water. ”
