I want to be a super cop

Chapter 375 Verification coincidence (Fifth update!)
"Isn't that rigorous enough?"

Ah Xiang was shocked when she heard the words, and immediately frowned, waiting for Zhong Tianzheng's opinion.

It seems that the blow is not enough.

Zhong Tianzheng shook his head again: "We can't say 70.00%, let's say 50.00%, [-]-[-]."

"..."

Ah Xiang is speechless.

Simply no longer speak.

"Come on, get up."

As Zhong Tian was speaking, he pulled Ah Xiang up, and the two stepped back, condescendingly looking down at the cleared area.

"Now, based on the clues we got, let me analyze the entire investigation site for you."

Zhong Tianzheng took off the disposable rubber gloves, took out a cigarette, lit it, took a deep breath, and then began to explain.

"The first point: the slice on the right is covered with a large amount of pesticides in the snow, which is very consistent with the setting of suicide by drinking medicine."

"Second point: Right in front of the area where Mr. Zhang is sitting, I scraped away all the snow layer by layer, but there is no pesticide residue in this area. This is very unscientific."

Ah Xiangfa asked, "Why?"

"Please, you old man, use your head to think about it."

Zhong Tianzheng rolled his eyes helplessly, and said angrily: "Brother, this is pesticide for people to drink. Pesticide, do you think it's refreshing to drink? The smell of pesticide is extremely pungent, and it makes people disgusted when it smells, let alone Say you opened your mouth to drink it, the first reaction to the pesticide entering your mouth should be a conditioned reflex to vomit out.”

"But there are no pesticide residues in the area directly in front. What does this mean?"

"Either he had made great mental preparations in advance and restrained his regurgitation, or someone blocked him, or the pesticide he spit out was sprayed on that person."

"Correct!"

Zhong Tianzheng snapped his fingers to express his agreement with this guess.

"Third: In the area on the left, I also dug out a small bead-like residue of pesticides, and the traces of pesticides fell down in spots. Don't you think it's strange?"

Ah Xiang retorted again: "You also said just now that the human body will vomit."

"Regurgitation, then it must have been sprayed out, and the traces of the pesticide will be different. This involves the free fall of physics and the potential energy of gravity."

Zhong Tianzheng took a heavy mouthful of his cigarette, and exhaled: "Let's use a simple analogy. A drop of water falls vertically. Under the action of gravity potential energy and angle, its trace should be that it collides with the ground head-on and then splashes around. It should be a central point and then explode around.”

"But if it landed obliquely, then its landing mark must be a point, and then a semicircular mark at a certain angle. If you look at the piece on the left, it is obviously a circular trace of pesticide residue."

Ah Xiang nodded thoughtfully.

These are some small details, she really didn't notice these things.

"The fourth point: that is the last point. The surface of the soil on the area of ​​our feet that we dug open has obvious traces of heel struggle and kicking. This shows that he was probably forcefully poured medicine into his mouth at that time." time, caused by struggle."

Zhong Tianzheng tilted his head slightly, and said hesitantly: "But this point is purely speculation, not rigorous enough, because no one knows what the specific reaction will be after drinking something highly poisonous, and the rejection given by each person's body. The reaction is also different, so I would say that it is not rigorous for you to make a homicide judgment based on this."

"Based on the above points together, I am more inclined to Zhang Lao not to commit suicide."

Zhong Tianzheng made the final conclusion, and then smoked his cigarette silently.

"Zi"

in the air.

All of a sudden there was only the sound of cigarette butts burning.

Ah Xiang's expression has become very shocked.

If the guess of the two of them is correct, then this matter is too terrifying.

The two passed by a crime inadvertently.

Ah Xiangdai frowned slightly: "What should we do now? Check for suspects?"

"Low-level error."

Zhong Tianzheng stomped out the cigarette butt, shook his head and denied: "When you find a clue, you must try to restore it yourself. If the things you restore can reach 50.00% coincidence with the crime scene, That means your guess is most likely correct, and you can proceed to the next step."

Zhong Tianzheng emphasized again: "Please note that it is extremely possible, not [-]%. You must always be aware of the direction of your investigation."

After finishing these words, Zhong Tianzheng was already walking towards another field.

Ah Xiang quickly followed.

soon.

Zhong Tianzheng found the nearest stack of haystacks, and he sat down directly next to the haystack, reaching out his hand to take out a bottle of Coke from his pocket.

"When did you bring another bottle of Coke?"

Ah Xiang blinked and looked at him curiously: "Your pocket is Doraemon's pocket."

"Can we be more professional?"

Zhong Tianzheng rolled his eyes: "That's not called a pocket, it's a four-dimensional pocket, or a treasure bag."

"Cut, childish."

Ah Xiang curled her lips in disdain: "I watch a lot of cartoons and still make fun of other people's ignorance."

Halfway through the words, Ah Xiang suddenly stopped.

In her mind, for some reason, the desk of Shi Xinyu appeared.

To be precise, it should be a table full of Doraemon dolls and figurines.

Sister Xinyu really likes Doraemon, right?

Zhong Tianzheng knows Doraemon so well. Could it be that they communicate frequently?

Just when she was about to have an attack, she saw that Zhong Tianzheng had already closed her eyes and meditated, and then quickly dismissed her irrelevant thoughts, and was ready to fight.

Zhong Tianzheng sat still.

At this moment, I let go of my mood to the extreme, brewing my own emotions, imagining myself as Mr. Zhang, and substituting myself into it.

Soon.

Zhong Tianzheng opened his eyes, without any superfluous expression on his face, he looked very sad.

He unscrewed the Coke bottle and put it in his mouth. He hesitated slightly when he smelled the pungent smell. After a while, he gritted his teeth, raised his head and poured the Coke into his mouth.

The moment the cola entered his mouth, he subconsciously felt sick in front of him, and a little bit of cola sprayed out from his mouth, falling into the white snow, leaving cola-colored spots.

Immediately afterwards, his heart stopped, and he continued to drink with his head raised.

Take a few bites.

Zhong Tianzheng couldn't bear it anymore, subconsciously threw away the Coke bottle in his hand, grabbed his neck with his palm, and scratched frantically, wanting to spit it out.

But all in vain.

Soon.

Severe dizziness came along with a burst of severe pain, Zhong Tianzheng couldn't hold on, and fell to the ground directly, his eyes turned white, and he wailed weakly.

It didn't take long.

Zhong Tianzheng was completely silent.
