Eight o'clock in the evening, the back entrance of the street park.

"Phew, this pervert!" Li Hui took a sip.

Han Bin shrunk his neck back: "Pay attention to saliva." ”

"You say that this Zheng Wen is actually hiding such important evidence?" Li Hui said.

This incident hit her a little hard, she may not have paid attention to it at the time, and afterwards, it was difficult to talk about it. Han Bin said.

"The park is full of people. ”

Han Bin and Li Hui, holding a stack of photos in their hands, stood at the gate of the park to investigate.

After the processing of the technical department, some frontal photos of the objects were obtained, and more images are still being processed, and it is estimated that there are some images, even after processing, it is difficult to see clearly.

Again, there are lights next to the entrance of the park, so you can see people entering and exiting clearly, otherwise, the pictures taken by the surveillance will be even more blurry.

When they see the person in the photo, they will stop and ask for it, and record their name, identity, phone number, and fingerprints.

Even if they weren't the people in the photos, the two would routinely ask if they had found anything unusual on the night of the crime.

This work, although not tiring, is not idle, and it is a tedious job.

Zhao Ming and Tian Li were at the front door, and they also painted gourds in the same way.

Days in a row.

The four of them all investigated in the street park and found more than 20 men who had committed crimes, and some men had clear images but had not been to the park these days, and their information could also be found on the Internet of the public security system.

Another afternoon, Han Bin lay in the office and rested in the morning.

"Papa......" A slap sounded, and Zeng Ping said: "Come and gather." ”

"Team Zeng, are you going to the street park to investigate?" Li Hui frowned.

"I won't check it today. ”

"Why?"

"The results of the DNA comparison are out. Zeng Ping said.

"The database is compared?" Han Bin said in surprise.

"It's compared, this is the suspect's information. Zeng Ping said, turned on the projector, and put the suspect's information.

Name: Jun Chen

Ethnicity: Han

Age: 28 years old

Height: 177cm

Job: Kotoshima Technology Company.

Family Status: Unmarried.

Address: Qindao City, Yuxin Road, Jiangxin Community, 6-703.

"Team Zeng, what are you waiting for, arrest someone. Zhao Mingdao.

......

The group drove to the Jiangxin community.

Pretending to be a property company, he deceived the door open.

The suspect Chen Jun was successfully controlled.

Chen Jun is a standard otaku, the house is very messy, the house is rented, and he is the only one who lives alone.

Han Bin and others searched carefully, but found no tools for committing the crime, and took the person back to the Public Security Bureau first.

In order to solve the case as soon as possible, Zeng Ping decided to interrogate him overnight.

......

Kotoshima Branch, interrogation room.

The suspect sat in the interrogation chair, and Han Bin and Li Hui were in charge of the interrogation.

Zeng Ping, Tian Li, and Zhao Ming were in the next room, listening through the one-way glass.

"Name, age, place of origin......" Han Bin began to ask as usual.

"Chen Jun, 28 years old, from Qindao City......"

"Do you know why I called you here?" asked Li Hui.

"No, I don't know. Chen Jun shook his head.

"We suspect that you are suspected of a rape case and hope that you will cooperate with the investigation. Li Hui said.

"How could it be! I've never done anything like that. Chen Jun looked shocked.

"Where were you last Monday, June 18 night?" Li Hui said.

"I don't remember exactly. Chen Jun said.

"Think about it. ”

After a moment, Chen Jun recalled: "I was at home. ”

"Can anyone prove it?"

"I live alone. ”

"That is to say, no one can prove that you didn't leave the house that night?" Li Hui said.

"Comrade policeman, I was really wronged. Chen Jun shouted.

"Every suspect who entered this room said that he was wronged, and it was not loud that he could prove his innocence. Li Hui said.

"I was so wronged!"

"Then let me ask you, why did your white genetic material appear at the scene of the crime?" asked Han Bin.

"Where's the scene?"

"Street Park. ”

"I've never been to that park at all. Chen Jun said.

"Don't pretend, if you haven't been to the scene, how can you have your white genetic material, this thing can't be faked. Li Hui said.

"I was wronged, something must have gone wrong. Chen Jun said.

"White genetic material is incriminating evidence, and if you can't explain why your genetic material is at the scene of the crime, no one can help you. Han Bin said.

"I really don't know. Chen Jun cried urgently.

......

An hour later, Han Bin and Li Hui left the interrogation room.

"How's that?" Zeng Ping said.

"The suspect did not have an alibi. Han Bin said.

"Any new clues?"

"The suspect's mouth was tight and he just said he didn't know. Li Hui said.

"The DNA comparison has been successful, and even if he doesn't admit it, it's useless. Zhao Mingdao.

"Team Zeng, I think there are still doubts in this case. Han Bin said.

"What's the doubt?"

"This Chen Jun doesn't look like he's lying. Han Bin said.

During the interrogation, Han Bin used the micro-expression analysis method to observe Chen Jun's every move, and found that Chen Jun was frightened and afraid, but there was no sign of lying.

This is not what a murderer should be.

"Is there any evidence?" Zeng Ping asked.

Han Bin shook his head, this was all his analysis.

"Han Bin, we are policemen, and we pay attention to evidence. Zeng Ping said earnestly:

"As long as Chen Jun did not have an alibi at the time of the crime, he could not explain his genetic material and why it appeared at the scene, and his suspicion could not be cleared. ”

"Yes. ”

"Okay, everyone is tired today, so let's get here first, and the trial will continue tomorrow. Zeng Ping said.

Back at home, Han Bin was still thinking about the case.

Micro-expression analysis error?

Or is there another real culprit!

With this question, Han Bin slowly fell asleep.

......

The next morning.

Huayuan Community, Room 1201.

After Han Bin got up, he washed up, changed into clean clothes, and went downstairs for breakfast.

Han Bin's parents also live in this building, room 601.

Han Bin's father's name is Han Weidong, who is also a police officer who works in the Guang'an Police Station, and his mother, Wang Huifang, is retired at home.

Han Bin entered the house and saw his father sitting at the coffee table drinking tea and reading the newspaper.

"Dad, haven't you seen enough at the police station?" Han Bin said with a smile.

"What do you kid know, live to be old and learn, I am learning national policies and actively responding to the call of the country. Han Weidong snorted.

"Where's my mom?"

"I went to the market to buy groceries. Han Weidong said.

"What's for breakfast?" Han Bin yawned.

"Go wash your hands, I'll serve you food. Han Weidong said.

"I still have this treatment?" Han Bin was a little flattered.

"Your mother said, you are a criminal police officer who is busy with work, so let me, a police officer, support your work more. Han Weidong snorted.

"It's still mother's consciousness. Han Bin said with a smile.

"Boom. ”

Han Bin washed his hands and went to the restaurant, where a plate of egg fried rice, a bowl of polenta, and a small plate of pickles and sauced beef were placed on the table.

"The food is good. Han Bin was also a little hungry, so he pulled two mouthfuls of egg fried rice, as if he remembered something: "Dad, is this rice leftover from yesterday?"

"Overnight rice, with less moisture, tastes better when stir-fried. Han Weidong said.

"Overnight? not the day. Han Bin said thoughtfully.

"Eat slowly, there's still in the pot. Han Weidong put down a sentence and went back to the living room to read the newspaper.

Han Bin had a few pieces of beef in sauce, finished eating egg fried rice, and didn't care about drinking corn porridge, so he hurried to the substation.

He has a speculation that may explain why the suspect's genetic material was present at the crime scene......
