Song Guyan is good about traveling, but he has nothing to say.

Accommodating soybean milk powder and not eating dog food, accepting his amazing spirituality, taking the initiative to admit mistakes when there are contradictions, and truly treating the police dog as an independent personality, which is very rare in many professional trainers.

People are not plants and trees, who can be ruthless. Watching Song Guyan get up early and be greedy and tirelessly investigate the case, Zhou You is still a little distressed.

Seeing the past love and the rich breakfast, Zhou You decided to help Song Guyan, so that she would not be stuck in a dead end and couldn't get out.

Taking advantage of Song Guyan's visit to the forensic laboratory to check the laboratory of the physical evidence he had just collected, Zhou You jumped onto the desk.

The police officers in the office were busy with their own affairs, and the strong support of the team leader and the achievements of the two girls made them feel like they were big chickens, and they wanted to make some achievements with a sigh of relief.

Fortunately, these people are busy, and they don't have time to pay attention to the Labrador's movements.

Zhou You turned over all the files and evidence related to the Jinzishan case, picked out the ones he wanted, and put them on the table.

It's like doing a difficult math problem, and at first glance there are a lot of words and graphics, which can be difficult to get started. But with a little bit of clarity, the whole mind will be much clearer.

It's like an initiation, it's a feeling of sudden enlightenment.

What Zhou You is doing now is to reflect his thoughts on the order of the case file, and provide Song Guyan with another way of thinking, not to be confined to her own confinement.

"How can there be no progress at all!" Xi Yao complained, "Is it that those people in the laboratory are not careful!"

"Don't talk nonsense, they also stayed up late to get tested. ”

"If you can't find conclusive evidence, you have to put Tong Menglin back today. Xi Yao frowned and said, "If she plans to escape, it will be difficult to catch her in the future." ”

"If we can't find evidence, people won't run away at all, but they will be more emboldened. Song Guyan smiled bitterly.

Without evidence, then legally speaking, Tong Menglin is innocent, and the police cannot restrict her life. Besides, there are so many industries in Jinzishan, Tong Menglin will not be willing to leave Shanghai. At least before selling these assets, the greedy Tong Menglin will never leave.

Song Guyan glanced at his desk and frowned slightly. As far as her memory is concerned, even if she randomly places the documents on the table, she will be a little impressed. What's more, it's obviously a reorganized desktop, and it's difficult not to react. Without this ability, where can you remember the situation at the scene, which is also a necessary skill for many criminal police.

However, Song Guyan did not have a great reaction, after all, this is in the city bureau, and the monitoring of outsiders is very strict. Probably a colleague was more curious and flipped it casually.

These files are top-secret documents for the general public, but they can be viewed at any time by the police officers within the six groups.

Wait a minute!

Song Guyan's heart moved, and his eyes on the desk became focused and fiery. The placement of these files is not irregular, and the logic of a solved case can be deduced in order.

Make bold assumptions and verify carefully. When solving a case, it is necessary to explore the mind, but it must be based on rational analysis.

Song Guyan keenly felt that the possibility of this hypothesis being true was very high, and if he continued to track down according to this line, he might be able to catch the murderer behind the death of Jinzishan.

"Xi Yao! Xi Yao!" Song Guyan shouted excitedly.

Xi Yao, who was buried in a large pile of case files, stood up smartly, and the files on the desktop were slammed to the ground.

"What's wrong, Sister Song?"

"Come with me and go to the villa in Jinzi Mountain!" Song Guyan said resolutely.

"Is there anything new?"

"Say as you go!" Song Guyan didn't have time to explain clearly to Xi Yao.

I finally opened up my mind a little, and if I couldn't verify it immediately, I would definitely be suffocated by myself.

Song Guyan only had the case in his mind, and he left in a hurry, but he didn't forget to bring the soybean milk powder.

Zhou You couldn't cry or laugh, is this considered digging a pit and pitting yourself?

Thoughts are such things, once opened, like a flood. On the way to the villa, Song Guyan was also sorting out his thoughts. Zhou You was able to discover new ideas with a lot of clues found, but he couldn't open his mouth, and he couldn't accurately pass them on to Song Guyan.

The arrangement of the case gave Song Guyan an idea, and she also had the opportunity to implement it, so that she could verify this guess, instead of just staying on the concept like Zhou You.

On the way to the villa, Song Guyan asked for the assistance of the police department, and his colleagues began to screen and sort out a large number of character relationships, especially the interpersonal relationship with Tong Menglin for more than ten years. But everyone who was in Shanghai, even Tong Menglin's classmates when she was a student, were turned out.

The police also have the authority to investigate the case, and they are not qualified to consult this information unless they have to. If it weren't for the fact that the Jinzishan case was too bad and too difficult to detect, the police would not have adopted this method.

Almost instantly, the civilian personnel of the entire city bureau participated in the screening of the relationship, hoping to provide Song Guyan with a lot of information.

"Hey, okay, okay! Thank you!" Song Guyan hung up the phone excitedly.

"I found out that Zhang Deshan and Tong Menglin used to be college classmates, but they later went to the army and graduated two years late. Song Guyan said excitedly.

"The boss of the security guard?" said Xi Yao with some surprise.

I met Zhang Deshan in a hurry before, and Xi Yao's impression of him was capable and decisive, and he was from a professional background at first glance.

Since he once had a relationship, Zhang Deshan had a motive to commit a crime. In addition, after all, if you have been in the military, you will more or less know some criminal investigation skills, and you will have the ability to commit crimes.

"Call for reinforcements, the two of us may not be enough. "Song Guyan is like a great enemy.

It's not Zhang Deshan, if it's really him, with his two years of military experience, plus such a long time of experience in front-line security work, to maintain physical fitness and combat effectiveness, Song Guyan really doesn't have enough confidence.

The army learns combat skills, and the moves are deadly. And what the police need is to defeat the enemy with one blow, not to take the lives of prisoners, it is enough to subdue them.

The difference in the purpose of training also determines the gap in actual combat. really fought, Song Guyan protected himself at most, and it was difficult to catch the other party, let alone subdue him.
