Detective from the future

Chapter 766 Association
Han Bin took the letter and checked it repeatedly, but did not see any obvious marks. The words on the letter were also printed, and the handwriting could not be recognized.

Han Bin asked, "When was the last time you checked the express locker?"

Song Jingshan thought for a while and replied, "It should be before the business trip. I left on the afternoon of September 6th, and checked the express cabinet on the morning of September 6th."

Han Bin did some calculations. Today is September 11th, and five days have passed. It is possible to deliver threatening letters within these five days.

"Has anyone read or touched this letter?"

"It's just me. I didn't tell my wife because I was worried. My daughter and my eldest son don't live with us either. I didn't tell them."

"When you took the letter, did you see any suspicious people around?"

"I was in a daze at the time, and I didn't care that much. I came directly to the police station." Song Jingshan leaned forward and asked with wide-eyed eyes, "Captain Han, you said that the person who wrote the threatening letter , could it be the murderer who killed my son?"

Han Bin put the threatening letter back into the envelope, "It's possible, have you ever received a threatening letter before?"

"Yes, I received it once before."

"When?"

"About three months ago."

"Do you remember the exact time?"

"Looks like June 6th."

Han Bin wrote down in his notebook, "Did you call the police?"

"Yes. I reported it to the police at the Huaguang Road Police Station. The police also went to my community to investigate, but they couldn't find the person who wrote the threatening letter."

"Is there any difference between that threatening letter at that time and this threatening letter?"

"There is no difference." Song Jingshan took out a letter from his pocket and put it on Han Bin's desk, "Look, this is the original letter."

It was also a white envelope with a piece of paper inside that said, "Song Jingshan, you must die, I will ruin your family sooner or later!" '

There is no difference between the two threatening letters.

Han Bin felt that something was wrong, "Since you have already reported to the police, the first threatening letter should be kept by the police as evidence, why is it in your hands."

"Hey, I got angry when you said this. I called the police, but it was useless. The police didn't catch anyone. They said it might be a child's prank. I felt something was wrong when I heard it. It obviously didn't take my case as a crime. It’s the same thing. Since the police station said it was a prank, there’s no way to file a case. I’m afraid they lost the threatening letter and are coming back.”

"What investigative methods did the Huaguang Police Station adopt at that time?"

"I went to two policemen, checked the express cabinet, and left the surveillance from the property. They said they wanted to go back to check the surveillance and asked me to wait for the notification at home." Song Jingshan sighed, "At first I reported There is no small hope, thinking that there may be news the next day, but who knows, I waited for a day and a day, and no one notified me after a week."

"In the second week, I took the initiative to call to inquire. The policeman who answered the phone said that he did not understand the situation and asked me to go to the police station to ask the policeman in charge of the case."

"I'm also right. This is for us. I really have to take the initiative. I went to the police station again and asked the person in charge of the case. They said that the monitoring had been completed and no suspicious persons were found. They also asked me if I had done it again. received a threatening letter."

"I said I didn't receive it again, and the policeman in charge of the case told me that it might be a prank, and asked me to go back and think about whether I had any conflicts with anyone recently, and said they would continue to investigate the case."

"I believe you are a ghost..." Song Jingshan became more and more angry, but considering that Han Bin and others were also policemen, he swallowed the latter words.

"Later, I waited another week and went to the police station again."

"Before I opened my mouth, people asked me if I had received any more threatening letters, and I said no."

"Well, people said it was a prank, and the evidence is insufficient to open the case, so this matter will be over." Speaking of this, Song Jingshan showed an angry look, and choked up, "If they find out who wrote the threatening letter earlier Maybe my son won't die!"

Han Bin didn't answer, and he couldn't answer this.

"In addition to checking the surveillance, has the police station done any other investigations?"

Song Jingshan thought for a while, "They said they had visited our community, but they didn't have anything to say."

Han Bin asked, "Have they conducted a technical test on that threatening letter?"

"I don't know about that." After finishing speaking, Song Jingshan showed a self-deprecating look, "Probably not, they didn't take the threatening letter seriously at all. In their words, I was not personally harmed. There is no loss of property, and there is no standard for filing a case at all."

Regarding this, Han Bin didn't say much, because the police officers at the police station probably acted in accordance with the regulations.If it is necessary to pursue responsibility, it is also a problem of the law enforcement agencies.

Han Bin can't control it, and he can't control it.All he can do is to handle the case at hand seriously and responsibly.

"Recently, have you noticed any other abnormalities?"

Song Jingshan pondered for a moment, then shook his head, "No. No one has looked for me, and something unusual happened. I thought it was a prank at first, but who would have thought... hey..."

"Three months ago, did you offend anyone?"

"I can't think of it, probably not. I have always been kind to others, and I value peace as the most important thing. I have never done anything wicked."

Han Bin said, "If you think about it carefully, you may have offended someone before, and the other party took action three months ago."

Song Jingshan was silent for a while, "I really can't remember."

"Captain Han, do you think the person who wrote the threatening letter is the murderer of my son? If he really wanted revenge on me, then I killed Bo Chen!"

Han Bindao, "I can't give you an accurate answer until the case is investigated. It's still what I said before. Think about who you are guilty of. If the murderer really came after you, what do you provide? Leads would be of great help to the police."

Song Jingshan took a deep breath, "I understand, I must think about it."

Then, Han Bin re-arranged the task again, because there was not enough manpower, he transferred two more players from the second group.

Then divide the players into three groups.

The first group was responsible for checking the mobile phone number, and the second group went to the Huaguang Police Station to understand the situation and adjust the file.

Han Bin took people to the community where Song Jingshan lived.

Before leaving, Han Bin sent both letters to the technical team and asked the technical team to help detect them.

……

Rongding Garden Community.

This community is not far from the Yuhua Sub-bureau. It is a high-end community with a high rate of greenery and large-scale houses.

Han Bin walked around the community. The monitoring facilities in the community are very complete. The entrance of the community, corridor entrance, elevator, and underground garage are all monitored.

Song Jingshan's family lives in Building No. [-].

There is no surveillance next to the courier cabinet in the lobby on the first floor, so there is no way to see who sent the threatening letter directly.

Han Bin walked around the community, and he already knew it in his heart.

Then, Han Bin took people to the property company.

The person in charge of the property company is Feng Lianhai, a middle-aged man in his 40s. After learning the identities of Han Bin and others, he behaved very politely.

"Captain Han, if you have anything to tell you, our property management company will definitely cooperate."

Han Bin said, "I want to retrieve the monitoring from September 6th to today."

"No problem, I can take you to the monitoring room now."

Han Bin asked Li Qin and Bao Xing to go to the monitoring room to adjust the monitoring, while he himself stayed in the property hall, "How many exits are there in Building No. [-] where Mr. Song is located?"

Feng Lianhai thought for a while, "There are two in total, one is coming out of the unit door, and the other is going directly out of the garage."

Han Bin asked, "If you go down the stairs to the garage, will you be caught by the camera?"

"Yes. The door to the underground garage from the stairway is facing a surveillance camera. As long as outsiders have entered the unit building, they will definitely be able to take pictures. In terms of community security, we are still very considerate."

"How many families live in Building No. [-]?"

Ma Lianhai opened his mouth and came, "Building No. [-] has seven floors, and each floor has two stairs and two households. There are fourteen households in total."

Han Bin nodded. This is the advantage of a high-end residential area. The ordinary residential area has [-] to [-] floors, two floors and four households. There are nearly a hundred residents in this unit.

It is good to have fewer households, which reduces the difficulty of investigation by the police.
