The Crime-Solving Madman In The City

If it hadn't suddenly occurred to him, Ye Yang would have never thought about ventriloquism.

But the world is so big and there are so many strange people that it creates this vast world filled with wonders.

A piece of calligraphy that continued the article "Float Skills" seemed to be the most important thing at this moment.

Although it cannot be used as evidence, it has become the biggest basis for determining that Guo Jie is the real murderer.

"Let's go back to the laboratory." Ye Yang reminded.

Lin Zi looked at him, thought for a moment, and said, "You don't still want to look for clues on the corpse, do you?"

"In addition to looking for clues from the corpse, we have no time to look for evidence now. It is impossible for such an excellent Guo Jie to leave us evidence. But Guo Jie is smart, and so is Yang Shu. Unless he is really beaten by a The hammer just hammered it to death, otherwise he would definitely leave something behind for us!"

A hammer has the potential to kill someone, and the possibility is very high.

But what if the poplar tree didn’t die on the spot? Maybe he struggled a little? There is also the first crime scene, Ye Yang, they have never found it!

Where will the first crime scene be?

Maybe hidden in the places where people think it is most impossible?

Where is the first crime scene that has been ruled out now?

The rooftop was a place excluded by the Zhou Dynasty!

Ye Yang and Lin Zi rushed back to the school as quickly as possible and went straight into the laboratory.

When Su Wanrong saw them coming back, she immediately asked, "Have you found any evidence?"

Ye Yang shook his head and said: "No, but it is certain that Guo Jie was involved in the case. Mom, now you and Li Duo will be busy for a while and conduct a more thorough inspection of the corpse. Especially the fingernails of the corpse. Oral cavity, see if you can find any new discoveries. And Zhou Chao, go prepare the luminol solution!"

When Zhou Chao heard the term luminol solution, he asked in surprise: "Have you found the scene of the first crime?"

"Not sure, but I want to use luminol solution to restore it on the rooftop to see if it is really the scene of the first crime as I guessed!"

Luminol reagent is not difficult to prepare. It can be prepared with luminol, soda, distilled water, and hydrogen peroxide.

However, the luminol detection method has a weakness, that is, the light emitted by it to display blood is extremely weak, so it must be carried out in darkness or in a place with good light shielding conditions.

Now, it is late at night!

Zhou Chao and Li Duo immediately went to prepare the reagents. After they were completed, Li Duo stayed to help Su Wanrong, while Ye Yang took Zhou Chao and Lin Zi to the roof of dormitory B!

However, the reagents prepared are limited, and it is impossible to prepare a large amount of luminol reagent in such a short time.

The three of them arrived on the rooftop. Zhou Chao and Lin Zi were both looking at Ye Yang, as if they were asking where to spray first.

Ye Yang looked around and said: "Guo Jie has a certain fighting ability, but it is unlikely that he can carry the body into the water tower. If you want Yang Shu to die unprepared, then this iron door is the best option." Good hiding place!”

"Zhou Dynasty, spray the luminol reagent along the straight line from the iron gate to the water tower!"

"good!"

Zhou Chao took the reagent and started spraying it little by little along the straight line pointed out by Ye Yang. As long as there was blood on the ground, it would be visible regardless of whether it was cleaned or how long it took.

The same detection method was mentioned in the TV series "Avenged". Although the reagent made by Song Ci at that time was not completely luminol, it had the same effect but had the same effect.

And in TV dramas, sometimes it’s not nonsense.

The reagents were slowly extending towards the water tower, but before Zhou Chao even reached the water tower, little bits of fluorescence began to appear on the ground, and an area of ​​that fluorescence was continuously expanding.

Ye Yang immediately took out his mobile phone to take pictures of the scene, until suddenly a pair of fluorescent footprints appeared in front of his eyes, Ye Yang immediately shouted: "Lin Zi, what size shoes does Yang Shu wear? "

"It seems to be 43."

"How big do you think the pair on the floor are?"

"It should only be thirty-seven!"

Lin Zi's face showed overwhelming joy when she spoke. The appearance of a pair of size 37 footprints at this time was simply incredible evidence.

Such small footprints rarely appear on men. Ye Yang has observed that Guo Jie's feet are relatively large among women. And thirty-seven is considered a big foot among women.

Ye Yang got close to the footprints and took a photo. Then he saw pairs of footprints slowly starting to appear.

Although those footprints fade with distance, that is just because the soles of the shoes were stained with blood and slowly dried!

Seeing that Zhou Chao had sprayed the reagent to the bottom of the water tower, Ye Yang shouted: "Spray again around the water tower and let me see if the appearance of the murder weapon can be revealed."

Zhou Chao nodded, and almost before he finished spraying, the image of a half-hammer was revealed.

Ye Yang smiled and exited the shooting mode, picked up his mobile phone and made a call to Su Wanrong.

"Mom, there's no need to test anymore. Has the city police department decided to hold a press conference?"

"It has been confirmed. It will be held at nine o'clock tomorrow morning on the playground of the Beijing Police Academy." Su Wanrong replied.

"Okay, let's call it a night and I'll invite Guo Jie to attend a press conference tomorrow morning!"
