Chapter 1868: : Childhood sweetheart chapter, another threat letter

Everyone swiftly said: "Thank you for the Hangzhou team's courteous treat, you go slowly!"
"Everyone, sit down, don't give it away." Hang Jin waved his hand and dragged Chi Yangyang away.
Leaving everyone's wide vision and walking outside the store, Chi Yangyang had time to speak: "Captain Hang Da, what else do you have?"
Hang Jin stunned her: "So you are stupid."
Chi Yangyang stared at him: "Speak well and we can still be friends."
Hang Jin said: "I am not familiar with them. What's the point of drinking with them? Besides, they are uncomfortable drinking with me. I am not happy to stay here for both parties. Interesting?"
"It's really true to hear you say that." Chi Yangyang smiled and took the initiative to take his arm. "But I think your performance today is very good. It looks like a leader."
Hang Jin hugged her in his arms: "Lao Tzu is a leader in the first place, so he looks like a leader."
Chi Yangyang was hugged by him, her cheek just pressed against his chest, and she gently nudged: "Anyway, I think you performed very well today anyway."
She never expected that Hang Jin could use this attitude to communicate with the people under her hands, and she didn't know that Hang Jin did so because of her in the team.
It doesn't matter if Hang Jin offends people. No one dared to show him his face. However, he was afraid that the little idiot Chi Yangyang would look behind those boys. The point is that the little idiot might not be able to see it.
Married such a little idiot and went home, and didn't think about her everywhere, what could he do?
After getting into Hang Jin's car, Chi Yangyang was about to start the car: "Then where are we going now?"
Hang Jin: "Find a place to eat whatever you want, and then go chat with the old man."
Chi Yangyang: "Does it have any purpose for being so active?"
Hang Jin: "The purpose is to make the old man like me, no?"
Chi Yangyang: "Yes, you can do whatever you want, Uncle Hang."
Hang Jin gave a wicked smile: "Is it okay? I only know after trying."
It took a long time for Chi Yangyang to understand what he meant: "Rogue!"
...
The carrion case is closed. There is no new case. Hang Jin brought all the members of the Cangshan Criminal Investigation Detachment to reorganize all the clues of the carrion case.
In the process of sorting out the clues, Hang Jin discovered that he had not found as important or even useful evidence at the crime scene before. Now that the case has been happening for so many days, they have gained nothing except to prove the identity of the deceased.
No useful clues were found in the files, and Hang Jin personally took people to the deceased couple's work and residence for two-point visits from house to house. The results were the same all the way.
All the neighbors said that the relationship between the deceased couple and their neighbors in the neighborhood was not good. They had never had any conflicts with others, and none of them had any motive for committing the crime.
Neighbors in the neighborhood couldn’t find clues here. Hang Jin checked with suppliers and diners. After visiting, he learned that the restaurant run by the husband and wife had been buying from fixed suppliers. They had cooperated for several years. There has never been a conflict, and none of the suppliers have any motives.
After excluding all acquaintances from committing crimes, for the first time, Hang Jin felt that criminal investigation was not as simple as imagined. Is this case really related to the case of the Chi family two years ago?
Just when Hang Jin was headless, he received an anonymous registered letter.
These years, there are so many different types of communication, who would choose to send registered mail?
Hang Jin didn't think much about it. He opened the letter and printed out two lines of words on a piece of A4 paper with a printer-Mr. Hang. There are some things you can never find out the truth, so why use your efforts in vain.
The writing was typed by the printer, and the handwriting was not visible.
Hang Jin immediately sent the letter paper to the Trace Department for examination. No fingerprints were found on the letter paper, nor any clues related to the sender.
Could not find the murderer, but received such a threatening letter.
The trace department member looked at Hang Jin: "Team Hang, this person has sent a threatening letter to our criminal investigation team. He simply doesn't put us in the eye. I will try to find a way to find the source of this letter."
"This kind of A4 paper can be bought in every stationery store on the street. How can you check the source of the letter paper?" Hang Jin didn't think about it that way, and asked people to check the material of this A4 paper. The result is no surprise.
Officer: "..."
Indeed, this behavior is like finding a needle in a haystack, and it may not be possible in the end.
Hang Jin said: "Zhao Ziqian, you personally lead people to organize all the materials of this case and send them to my office. Everyone focuses on other things. I have other plans for this case."
Judging from the threatening letter, this corpse case is inseparable from the case of the Chi family two years ago.
Just the little four eyes...
Hang Jin is still worried about her.
...
Hang Jin unknowingly walked outside Chi Yangyang's office. He cleared up his emotions, pushed the door and walked in: "Chi Da forensic doctor, what are you up to?"
Chi Yangyang didn't raise his head and said, "What are you doing?"
Hang Jin: "You are so sorry that the chief forensic doctor of Cangshan Criminal Investigation Detachment is idle at work?"
Chi Yangyang put down the folder in his hand and looked up at Hang Jin: "If I don't work, there will be no criminal cases. This is a good thing. I wish I was so leisurely every day."
But Hang Jin saw that she was not idle, and took two steps to grab the documents in her hand: "I just want to see what insignificant documents Chi Forensic is looking at during working hours."
Chi Yangyang reached out to grab it back, but it was too late. Hang Jin had opened the folder and saw the contents of the folder.
Hang Jin's face sank, not angry but worried: "Where did you get these files?"
Chi Yangyang: "As a forensic doctor, what's the difficulty in getting an old file?"
Hang Jin darkened his face: "To be honest."
Chi Yangyang didn't say a word.
Hang Jin said again: "The record of the father-in-law case has been handed over to the State Administration for management. It is not easy for me to get it. How did you get it?"
Chi Yangyang still didn't speak, but Hang Jin quickly thought of a suspect, and couldn't help raising his voice: "Why is that kid Jiang Zhen giving you this kind of thing?"
"My parents' case has many doubts. As their daughter and a forensic doctor, what is the problem with calling out their files?" Chi Yangyang always knew that Hang Jin was helping him investigate the case two years ago. Suddenly hearing him say this, she didn't know why she got angry, "Hang Jin, I want to ask you what's your heart?"
What is his peace of mind?
His peace of mind is very simple, that is, to help her find the murderer who killed her parents in the past under the guarantee of her safety, so he will prevent her from committing the danger alone, but this little idiot knows that this road will continue down. How dangerous.
