Chapter 766

Han Bin took the letter to repeatedly check, did not see the obvious mark, the letter is also printed out, unable to recognize the handwriting.

Han Bin asked, "when was the last time you checked the express cabinet?"

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

Han Bin calculated that today is September 11, and five days have passed. It is possible to send threatening letters in these five days.

"Who has read and touched this letter?"

"I'm alone. I'm afraid of my wife, so I didn't tell him. My daughter and my eldest son don't live with us. I didn't tell them

"Did you see any suspicious people around when you took the letter?"

"I was so confused that I didn't care so much. I went straight to the police station. " Song Jingshan leaned forward, widened his eyes and asked, "Captain Han, do you think the person who wrote the threatening letter is the one who killed my son?"

Han Bin put the threatening letter back in the envelope, "it's possible. Have you received threatening letters before?"

"Yes, I've received it once before."

"When?"

"About three months ago."

"Do you remember the exact time?"

"It's like June 10th."

Han Bin wrote down in his notebook, "did you call the police at that time?"

"Yes. I report to the police in Huaguang Road police station. The police have also investigated my neighborhood, but they have not found anyone who wrote a threatening letter. "

"Was there any difference between that threatening letter and this one?"

"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, which said, "Song Jingshan, you have to die. Sooner or later, I'll let your family die!"

There is no difference between the two threatening letters.

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

"Hey, I'm angry when you say that. I called the police, but it's useless. The police didn't catch anyone, saying it might be a kid's prank. As soon as I heard it, I felt something was wrong, which obviously didn't take my case for granted. Since the police station says it's a prank, it's impossible to file a case. I'm afraid they'll lose the threatening letter and come back. "

"What investigation methods did Huaguang police station adopt at that time?"

"I went to two policemen and checked the express cabinet. I had to go back to check the monitoring from the property. I was told to wait for the notice at home." Song Jingshan sighed, "at the beginning, I still had a lot of hope. I thought that there might be news the next day. Who knows, one day, after a week, no one told me."

"The next week, I took the initiative to make a phone call to ask. The policeman who answered the phone said he didn't know the situation and asked me to go to the police station in person to ask the policeman in charge of the case."

"I'm also right. It's for us. We really have to take the initiative. I went to the police station again and asked the person in charge of the case. As a result, they said that the monitoring had been finished and no suspicious person was found. They also asked me if I had received any more threatening letters. "

"I said I didn't receive it again. The policeman in charge of the case told me that it might be a prank. Let me go back and think about whether there has been any conflict with others recently, and said that they would continue to investigate the case."

"I believe you, ghost..." Song Jingshan said more and more angry, but considering that Han Bin and others are also police, the words behind or swallow in.

"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. I said no."

"Well, they say it's a prank. There's not enough evidence to put the case on file, so it's over." Speaking of this, song Jingshan looked angry and choked, "if they had found the person who wrote the threatening letter earlier, maybe my son would not have died!"

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

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

Song Jingshan thought, "they said they have visited our community, but there is no following."

Han Bin asked, "have they ever done a technical test on that threatening letter?"

"I don't know." With that, song Jingshan showed a look of self mockery, "I guess not. They didn't take the threatening letter seriously at all. In their words, I didn't suffer any personal injury or property damage, so it doesn't constitute the standard for filing a case."

In this regard, Han Bin did not say much, because the police station is likely to act in accordance with the provisions. If it is necessary to investigate the responsibility, it is also a problem for the judicial organs.

Han Bin can't manage it, neither can he. What he can do is to handle the case in hand conscientiously and responsibly.

"Recently, have you found any other abnormalities?"Song Jingshan pondered for a moment and shook his head, "No. No one ever came to me, and something unusual happened. Originally I thought it was a prank, but who ever thought Ah... "

"Did you offend anyone three months ago?"

"I can't remember. I don't think so. I've always been kind to others and valued harmony. I've never done anything immoral. "

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

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

"Captain Han, do you think the man who wrote the threatening letter was the murderer of my son? If he really wanted to revenge me, then I killed bochen!"

Han Bin said, "before the case is clear, I can't give you an accurate answer. As I said before, think about the culprit. If the murderer is really aimed at you, the clues you provide will be of great help to the police. "

Song Jingshan took a deep breath," I see. I must miss it very much. "

Then, Han Bin rearranged the task, because the manpower was insufficient, he transferred two team members from the second group.

Then divide the players into three groups.

The first group is responsible for checking the mobile phone number, and the second group is going to Huaguang police station to find out the situation.

Han Bin is to take people to live in Song Jingshan district.

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

……

Rongding Garden community.

This district is not far from Yuhua Branch Bureau. It belongs to high-grade district with high greening rate. It's all big houses.

Han Bin turns around in the community. The monitoring facilities in the community are very complete. There are monitoring facilities at the entrance of the community, the entrance of the corridor, the elevator and the underground garage.

Song Jingshan's family lives in building 6.

There was no monitoring at the express cabinet inside the hall on the first floor, so there was no way to see who put the threatening letter directly.

Han Bin turns around in the residential area, and he already knows something about it.

Then, Han Bin took people to the property company.

The person in charge of the property company is Feng Lianhai, a middle-aged man about 40 years old. After learning the identity of Han Bin and others, he was very polite.

"Captain Han, please let me know if you have any orders. Our property management company will cooperate."

Han Bin said, "I want to transfer the monitoring from September 6 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 monitor, while he himself stayed in the property hall. "How many exits are there in the sixth building where Mr. Song is located?"

Feng Lianhai thought, "a total of two, one is from the unit door, one is directly under the garage."

Han Bin asked, "if you take the stairs down the garage, will it be captured by the camera?"

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

"How many families live in building six?"

Ma Lianhai opened his mouth and said, "building 6 has seven floors, two stairs and two households on each floor. There are 14 households in total."

Han Bin nodded, this is the advantage of high-end community, ordinary community is 20 or 30 floors, two ladders four households, this unit has nearly 100 households.

It is beneficial to have fewer residents, which reduces the difficulty of police investigation.
