Chapter 74 Determining the Source
On the way back, Wang Zhong became taciturn.
There were few pedestrians and not many vehicles on the waterlogged streets, but Wang Zhong stared out the window with dull eyes.
When they were almost at the criminal police team, Wang Zhong asked: "Are we too useless?"
Jiang Yuan frowned tactically: "Us?"
"What I mean is that we who are engaged in technology, you see, if the conditions are not met, it will be impossible to solve the case. Just say, it's just a heavy rain, surveillance, surveillance can't see, fingerprints, fingerprints can't be scanned, footprints, footprints It doesn't match..." Wang Zhong muttered and said, "I know that many major unsolved cases have not been solved because of heavy rain. But when I really encounter such a case, I feel quite uncomfortable."
Jiang Yuan said "oh".
"Don't you understand?" Wang Zhong was a little disappointed. We are all technicians, so we should feel the same way.
Jiang Yuan drove the car, looked ahead, and said: "Understanding is understanding, but there is a feeling of powerlessness, right?"
"Yes! The feeling of powerlessness is summed up well, that's it, so you still understand..."
"But today's case hasn't reached the point where I feel powerless." Jiang Yuan interrupted Wang Zhong's wailing.
Wang Zhong sat up straight and asked, "No? It's raining so heavily..."
"It's not raining in the store." Jiang Yuan glanced at Wang Zhong and said, "Isn't the focus of our on-site investigation the store?"
Wang Zhong was excited when he heard that, yes, the focus of today's investigation is the store.
Wang Zhong asked hurriedly: "Did you get fingerprints or something?"
"I don't think there are any fingerprints. Let's go back and take a look." Jiang Yuan had several plans in mind, but he didn't say them out.
Some things are too tiring to talk about empty-handedly, and if you don't get it right, you will have to enter the debate stage. It is better to do it before talking about it.
Wang Zhongxian became more active, parked the car with Jiang Yuan, and chased Jiang Yuan to the office.
As they approached the office building, they saw Jiang Yuan turning a corner and entering the police dog squadron's camp.
Wang Zhong was surprised: "You want to use a dog?"
"Have you had lunch?" Jiang Yuan asked Wang Zhong.
"Oh...oh, I forgot." Wang Zhong touched his head sheepishly and said, "Then let's eat first. Should we eat fried rice or buy it from the canteen?"
Jiang Yuandao: "Make it yourself and eat it with the dog. I promised Da Zhuang before."
Wang Zhong's eyelids wrinkled when he heard this: "I understand the first sentence of these few words you said."
Just as he was talking, Da Zhuang rushed over with a chain in his hand.
The sound of the chain being pulled instantly exploded in the police's ears, which was even more sensitive than the sound of gunshots. Wang Zhong couldn't help but stepped back and put his hands in front of his chest.
Da Zhuang let out a "woof" and without even looking at Wang Zhong, he wagged his tail crazily towards Jiang Yuan. The dog's face is full of expressions of cuteness to please, resentment to please, and ecstasy to please.
"The vegetables and meat are ready." Li Li also heard the noise and rushed out of the kitchen. She looked at Wang Zhong again and asked, "One more?"
"Make some noodles and make a little more juice when cooking. It will be delicious. Master and I can't eat too much." Jiang Yuan has mastered the LV5 dog rice skills and can make it very flexibly.
Wang Zhong was a little embarrassed and said with a smile, "It's the same thing if I make some instant noodles."
"No need." Jiang Yuan waved his hand. When the LV5 dog rice is ready, Wang Zhong will be eating instant noodles next to him. Wouldn't it be even worse than Da Zhuang?
Don't let him steal Da Zhuang's meal and affect the growth and development of other people's police dogs.
"Then let me help." Wang Zhong once again expressed his willingness to be proactive.
At this time, Da Zhuang watched Wang Zhong touch the ingredients, and he couldn't wait to "bark", and the dog's leash suddenly made a clattering sound.
"Da Zhuang, sit down." Li Li shouted.
Da Zhuang sat at the door aggrievedly, staring at Wang Zhong with an expression of "If you dare to touch me again, try it."
Wang Zhong swallowed and quickly stood next to Li Li.
Li Li's expression was calm, her eyebrows drooped like a Rottweiler, she patted Wang Zhong's shoulder skillfully, and said: "Stop making trouble, Da Zhuang won't let me interfere when Jiang Yuan is cooking. The dog is big." , have their own ideas.”
Wang Zhong laughed twice.
"Bring me a mobile phone holder." On the other side, Jiang Yuan used his mobile phone to play the surveillance video of Xinfayan Hotel and set it up in front of the pot to play it in a loop.
Watching the video on his mobile phone, he couldn't see it very clearly, but Jiang Yuan didn't really care.
It can enhance the picture or a certain point in the video by reducing noise, collaborative filtering, etc.
However, for Jiang Yuan now, what matters is not the technology, but where it is applied.
In the video, the robber was holding a sharp knife and wrapped himself tightly in a hoodie, leaving only his eyes exposed. Looking at it from beginning to end, even though I was panting tiredly, I had no intention of opening it.
For this, noise reduction and collaborative filtering are obviously useless.
If you want to see faces, you need perspective skills, which is obviously not allowed!
Instead, Jiang Yuan wanted to use this method to remind himself where the enhancement was really needed.
The fatty meat is being stir-fried, the beef is being boiled, and the seafood is being steamed...
Jiang Yuan manipulated the ingredients step by step, making Li Li and Da Zhuang salivate.
At the same time, he has been considering all aspects of the video in his mind and sorting the questions that come to his mind.
He has many choices, not no clues.
A lot of the information that appears in the video can be tried and explored. For example, the hoodie was most likely purchased online. If the source can be confirmed, it is possible to find information about the suspect.
The suspect's shoes were also exposed many times, and the sacks used to transport cigarettes back and forth could also be a direction for investigation. Of course, what Jiang Yuan paid most attention to was the weapon in the suspect's hand!
A short sword half as long as an arm.
It can be seen that the blades are opened by oneself. Even so, two such long knives are not easy to buy casually.
However, Jiang Yuan was not sure whether the source could be determined. The details will depend on the pictures.
When the meal was ready, Jiang Yuan scooped out Da Zhuang's portion first and glanced at Da Zhuang subconsciously.
Da Zhuang immediately pouted, as if he wanted to smile to Jiang Yuan, who seemed to be smarter than everyone else.
