Chapter 74: Confirming the Source

On the way back, Wang Zhong became silent.

The water-logged streets had few pedestrians, and there were not many vehicles, but Wang Zhong stared out the window, his eyes listless.

Almost at the Criminal Police Detachment, Wang Zhong asked: "Are we too useless?"

Jiang Yuan tactically frowned: "We?"

"I mean those of us who do technology. Look, the conditions are not met, and the case cannot be solved directly. You say, it's just raining heavily, surveillance, surveillance can't be seen, fingerprints, fingerprints can't be swept, footprints, footprints can't be matched..." Wang Zhong muttered, saying: "I know, many major unsolved cases are because of the heavy rain, so they weren't solved. But when I really encounter such a case, I feel quite uncomfortable in my heart."

Jiang Yuan gave an "Oh."

"Don't you understand?" Wang Zhong was a bit disappointed. Everyone was a technical person, so they should empathize.

Jiang Yuan was driving, looking ahead, and said: "Understanding is understanding, it's just a sense of powerlessness, right?"

"Right! Sense of powerlessness, this is summarized well, that's it, so you still understand..."

"But today's case hasn't reached the level of powerlessness yet." Jiang Yuan interrupted Wang Zhong's wailing.

Wang Zhong sat up straight and asked: "Hasn't it? Such heavy rain..."

"It didn't rain in the shop." Jiang Yuan glanced at Wang Zhong and said: "The focus of our scene investigation is inside the shop, right?"

Wang Zhong felt a jolt, right, the focus of today's investigation was inside the shop.

Wang Zhong hurriedly asked: "Did you sweep any fingerprints, or anything?"

"Fingerprints are estimated not to be there. Let's go back and see." Jiang Yuan had several plans in his heart, but didn't say them out.

Some things, talking about them empty-to-empty was too tiring, and if it didn't work, it would enter the debate link, so it was better to do it and then say it.

Wang Zhong felt more active, stopped the car with Jiang Yuan, and chased Jiang Yuan to the office.

Almost at the office building, Jiang Yuan turned a corner and entered the camp of the Police Dog Squadron.

Wang Zhong was surprised: "Need to use a dog?"

"Have you had lunch?" Jiang Yuan asked Wang Zhong back.

"Oh... oh, forgot." Wang Zhong touched his head embarrassedly and said: "Then let's eat first, eat fried rice or buy from the cafeteria?"

Jiang Yuan said: "Make it yourself, eat with the dog. Promised Dazhuang before."

Wang Zhong's eyelids wrinkled: "I only understood the first sentence of what you said."

Just as he was talking, Dazhuang had already rushed over with a chain.

The sound of the iron chain pulling instantly exploded in the policeman's ear, which was even more sensitive than the sound of a gun. Wang Zhong had already retreated a step, and his hands were placed in front of his chest.

Dazhuang gave a "Woof," didn't even look at Wang Zhong, and wagged his tail frantically at Jiang Yuan. The dog's face was full of expressions of selling cuteness, resentment, and ecstasy.

"Vegetables and meat are all prepared." Li Li also heard the movement and rushed out of the kitchen, then looked at Wang Zhong and asked: "One more?"

"Get some noodles, and when boiling vegetables, make a little more juice, it's also very delicious. Master and I can't eat too much." Jiang Yuan mastered the LV5 dog food technique, which could be done very flexibly.

Wang Zhong was a bit embarrassed and smiled: "I'll get some instant noodles to eat, it's the same."

"No need." Jiang Yuan waved his hand. When the LV5 dog food was made, Wang Zhong was eating instant noodles on the side, wouldn't it be even more miserable than Dazhuang.

Don't let him snatch Dazhuang's food and affect the police dog's growth and development.

"Then I'll help." Wang Zhong expressed his active initiative again.

At this time, Dazhuang watched Wang Zhong about to touch the ingredients, and couldn't wait to "Woof" out, and the dog chain immediately rattled.

"Dazhuang, sit down." Li Li shouted.

Dazhuang sat at the door aggrievedly, staring at Wang Zhong, with an expression of "try touching it again."

Wang Zhong swallowed his saliva and hurriedly stood beside Li Li.

Li Li's expression was calm, her eyebrows drooped like a Rottweiler, she patted Wang Zhong's shoulder very skillfully, and said: "Don't make trouble, when Jiang Yuan cooks, Dazhuang doesn't let me intervene. The dog is big and has its own ideas."

Wang Zhong laughed twice.

"Get me a phone stand." On the other side, Jiang Yuan used his phone to play the surveillance video of Xinfa Tobacco and Liquor Store, and placed it in front of the stove to loop.

Watching the video with a phone wasn't very clear, but Jiang Yuan didn't care much.

He could enhance the image or a certain point in the video by reducing noise, collaborative filtering, etc.

However, for Jiang Yuan now, what was important wasn't technology, but where it was applied.

In the video, the robbers held sharp blades and wrapped themselves tightly in hoodie sweatshirts, revealing only a pair of eyes. Looking from beginning to end, even if they were tired and panting, there was no intention to lift it.

For this kind of thing, what noise reduction, what collaborative filtering, were obviously useless.

To see the face, what was needed was the perspective skill—this obviously wasn't allowed!

Jiang Yuan instead wanted to use this way to remind himself where enhancement was truly needed.

Fat meat was stir-frying, beef was boiling, seafood was steaming...

Jiang Yuan operated the ingredients step by step, making Li Li and Dazhuang drool.

At the same time, in his mind, he had been considering all aspects of the video, and sorted the problems he thought of.

He had many choices, rather than not finding clues.

Many pieces of information appearing in the video could be tried to explore. For example, the hoodie sweatshirt was very likely bought online. If the source could be confirmed, it was possible to find the criminal suspect's information.

The suspect's shoes were also exposed many times, and the sacks used to transport cigarettes back and forth could also be an investigation direction. Of course, what Jiang Yuan paid most attention to was the weapon in the suspect's hand!

A short knife half an arm long.

It could be seen that the blade was opened by himself. Even so, such two long knives weren't things that could be bought casually.

However, whether the source could be confirmed, Jiang Yuan wasn't very sure. Specifically, it depended on the picture.

The food was ready, Jiang Yuan first scooped out Dazhuang's portion, and subconsciously looked at Dazhuang.

Dazhuang immediately pouted, as if wanting to smile at Jiang Yuan, looking smarter than everyone else. ===== CHAPTER 75 =====
