Detective from the Future

To

Han Bin asked the property company for a list of the owners of Building 6 and their contact information, which will be needed for investigation and monitoring.

As for the courier cabinets in Building 6, there is a gap above each cabinet, which is specially used to deliver letters. The probability of leaving DNA and fingerprints is very small, and even if there is, it may not be the murderer.

After Li Qin and Bao Xing finished copying the monitoring, the site survey was basically completed, and Han Bin took the people back to Yuhua Branch Station.

After Han Bin returned to the office, he found that Li Hui had returned from the Huaguang Police Station. “You kid is fast.”

Li Hui said, “After handing over with the comrades at the police station, I will be back.”

Han Bin yawned and sat on the chair, “What clue do they have?”

“After receiving Song Jingshan’s alarm, they made a special trip to the neighborhood where Song Jingshan lives, and they also copied the neighborhood surveillance video.” Li Hui put a copy of the information in front of Han Bin, “This is the time The file contains Song Jingshan’s transcripts and the history of their investigation.”

Han Bin looked through the files and found that Song Jingshan’s transcript is roughly the same as today’s transcript.

However, there is a transcript that caught Han Bin’s attention. According to Song Jingshan’s account, he found that there were more letters in the express cabinet on the morning of June 10, and the last time he checked the express cabinet was on the morning of June 8. Said that the last time the crime was committed was between June 8th and June 10th.

In the previous transcript, Han Bin also asked about the first threatening letter and the exact time, but Song Jingshan only remembered that it was the police who reported to the police on June 10th and found the threatening letter last time. The time of the express cabinet can’t be remembered.

Except for this, there are no other valuable clues in the file, and the investigation process is also very simple.

Han Bin threw the file on the table and glanced at the crowd, “Don’t say anything, check the surveillance.”

“Not only should the surveillance of the last five days be checked, but also the surveillance on June 8, June 9, and June 10, but also the surveillance video of the first threatening letter and the second threatening letter Compare and find out the common characteristics of the suspects.”

“Yes.” Everyone split up.

Not long after, Du Qi also returned from the communications company. He was responsible for investigating Zhao Ge’s call records to see if he could find any clues about Zhao Ge from his contacts.

After Du Qi reported to Han Bin, Han Bin asked him to take Mai Jun to check together.

This is also a tedious job.

Han Bin poured a cup of tea and stood by the window thinking about a case.

This threatening letter may seem a little abrupt, but if you think about it, you will find that the timeline of the threatening letter is probably before Song Bochen’s death.

Song Jingshan was on a business trip on September 6, which means that during the four days of the 6th, the 7th, the 8th, and the 9th, the suspect may deliver the threatening letter, and Song Bochen died on the afternoon of September 9th. .

The murderer probably sent a threatening letter first, and then killed Song Jingshan’s son Song Bochen out of revenge.

Song Bochen’s death also coincided with the sentence of family destruction and death.

However, if the murderer has decided to kill, what is the point of sending a threatening letter?

Is it possible that to remind Song Jingshan? This doesn’t make sense.

Of course, there is also a threatening letter that may be delivered after the murderer killed someone. The purpose is to stimulate Song Jingshan.

If this is the case, the two people’s enmity will be great.

It stands to reason that there is such an irreconcilable contradiction between the two parties. Song Jingshan should have known it, but Han Bin asked again and again, but Song Jingshan said that he did not have enemies.

Han Bin picked up the cup to drink tea, but found that the tea in the cup had bottomed out.

Han Bin poured another cup of tea.

Han Bin also has a speculation whether this is a trick for the murderer.

The target of the murderer was Song Bochen, and he also made vengeance with Song Bochen, but in order to divert the police’s attention, he sent a threatening letter to Song Jingshan. The purpose was to let the police track down the situation around Song Jingshan, thereby ignoring the clues around Song Bochen.

If this is the case, it means that the murderer started planning three months ago, or even earlier

At noon, Han Bin had a meal in the cafeteria, and talked to Zeng Ping about the case during the meal. They are still tracking two vehicles with a license plate. They have locked the general direction and location, but it will take a while to find Suspect vehicle.

After dinner, Han Bin took a lunch break as usual.

At two o’clock in the afternoon, I washed my face and refreshed.

There has been no progress in monitoring. Han Bin is somewhat dissatisfied with their efficiency. In the afternoon, he is also ready to invest in verification and monitoring.

“dong dong” There was a knock on the door outside the office.

“Come in.”

Lu pushed the door and walked in and said with emotion, “Team Korea, every time I see you in the office, I feel like a dream.”

Han Bin shook his head and laughed, “Is there anything to notice?”

“No clue, I don’t dare to go to your door.” Lu handed over a copy, “We have checked two envelopes, and only one person’s fingerprint was found on the second threatening letter. After comparison, it is Song Jingshan’s fingerprint.”

“Four fingerprints were found in the first threatening letter, one is Song Jingshan, one is Song Bohui, and there are two fingerprints. There is no comparison sample for the time being.”

Han Bin touched his chin. He asked Song Jingshan before. According to Song Jingshan, when he found the first threatening letter, he found Song Bohui and his daughter Song Boxia. In other words, in addition to Song Jingshan, Song Bohui and Song Bohui Song Boxia has read this threatening letter.

The fingerprints of Song Jingshan and Song Bohui are matched, and Song Jingshan’s words are also confirmed from the side, but I don’t know if Song Boxia’s fingerprints are in the remaining two fingerprints.

Han Bin briefly told Lu about the situation and asked him to go back and wait for the news. Han Bin must first determine whether there are Song Boxia’s fingerprints in the two fingerprints. If there are, it can be ruled out temporarily.

In this way, when comparing databases, the workload will be reduced by half, which is also considered for the sake of the technical team.

After Lu left, Han Bin slapped his hands and said to everyone, “You should have heard what you said just now. The Technical Division found suspicious fingerprints on the first threatening letter, which is most likely left by the suspect Next, as long as you find a suspicious person from the surveillance, you can compare the fingerprints. Everyone will work harder.”

The crowd responded sparsely.

Han Bin ignored them and called Song Jingshan to tell his daughter Song Boxia to come to Yuhua Branch Station.

However, Song Boxia didn’t wait, but Han Bin waited for another guest.

“ding ling ling” Han Bin’s cell phone rang.

“Which one?”

“Is this Han Section Chief?”

“It’s me, who are you?”

“Do you check the threatening letter case again?”

“Yes.” Han Bin was a little puzzled.

“I have some situations that I want to respond to you.”

“What’s the situation?”

The person on the other side of the phone hesitated, “Can I tell you face to face, I can’t explain this matter in a single sentence.”

“Yes, where are you?”

“I’m at the door of Yuhua Branch Station. UU reading www.uukａnshu.com ”

Han Bin walked to the window and saw a man standing next to the guard’s room, “You come into the hospital, I will let someone pick you up.”

“Good.”

Hanging up the phone, Han Bin greeted Zhao Ming and asked him to go downstairs to pick up the man who called.

After a while, Zhao Ming walked in with a middle-aged man, wearing a gray T-shirt, with his head down, looking a little cramped.

“Please sit down, what do you call it?” Han Bin asked.

“My surnamed Hong, my name is Hong Jianying.”

“I think you are a bit familiar, have we met somewhere?”

“Yes, I work in Rongding Garden neighborhood property.”

“I remember, I saw your photo in the property, you are responsible for cleaning the 6th building.”

Tian Li handed a glass of water, Hong Jianying caught the glass with both hands, “Yes, you have a good memory.”

The other party is the cleaner of Building 6, and it is very likely that he has seen the person who delivered the threatening letter. Han Bin subconsciously asked, “Do you have any clues to threaten the suspect?”

“I” Hong Jianying swallowed and took a deep breath, “I wrote that letter!”
