At eight o'clock in the evening, at the back gate of Jiexin Park.
"Bah, this pervert!" Li Hui spat.
Han Bin shrank his neck back: "Pay attention to the saliva."
"You say that this Zheng Wen actually concealed such important evidence?" Li Hui felt a little resentful.
"This incident hit her a little bit. She might not have noticed it at the time, and it was hard to talk about it afterwards."
"There are people in the park."
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 by the technical department, some frontal photos of the investigation objects were obtained. More images are still being processed. It is estimated that some images are difficult to see even after processing.
This is because there is a light next to the entrance of the park, so that people who enter and exit can be seen clearly, otherwise the pictures captured by the surveillance will be more blurred.
When they see the person in the photo, they will stop and ask, and record their name, identity, phone number, and fingerprints.
Even if it is not the person in the photo, the two will routinely ask if anything unusual was found on the night of the incident.
Although this job is not tiring, it is a cumbersome job.
Zhao Ming and Tian Li were at the front door, doing the same thing.
for several days.
The four of them searched in the park in the middle of the street, and found more than 20 men who had time to commit the crime. Although some men had clear images, they had never been to the park these days. They could also be found on the Internet of the public security system. information.
It was another afternoon, and Han Bin lay down in the office for a morning break.
"Papa..." There was a burst of applause, and Zeng Ping called out to everyone: "Come and gather."
"Captain Zeng, are you going to investigate the park again?" Li Hui said in a low tone.
"There will be no investigation today."
"Why?"
"The DNA comparison result is out." Zeng Ping took out a document from his bag.
"Has the database been compared?" Han Bin asked.
"The comparison works. The suspect was arrested for provoking trouble. Here is his information." Zeng Ping said, turning on the projector and displaying the suspect's information.
Name: Chen Jun
Nationality: Han
Age: 28 years old
Height: 177cm
Work: Qindao Technology Company.
Family status: single.
Address: Qindao City, Yuxin Road, Jiangxin Community, 6-703.
"Captain Zeng, what are you waiting for, arrest someone." Zhao Ming was gearing up.
…
A group of people drove to Jiangxin Community.
Pretending to be a real estate company and tricked him into opening the door.
The suspect Chen Jun was successfully controlled.
Chen Jun is a standard nerd, his home is messy, the house is rented, and he lives alone.
Han Bin and the others searched carefully, but did not find any tool to commit the crime, so they took him back to the Public Security Bureau.
In order to solve the case as soon as possible, Zeng Ping decided to interrogate overnight.
…
Qindao 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 nearby observation 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?" Li Hui asked.
"No, I don't know." Chen Jun shook his head.
"We suspect that you are involved in a rape case and hope you cooperate with the investigation."
"How is it possible! I've never done such a thing before." Chen Jun showed shock.
"Last Monday, the night of June 18th, where were you?" Li Hui asked.
"I can't remember."
"Think about it."
Chen Jun recalled for a moment: "I am at home."
"Can anyone prove it?"
"I live alone."
"That is to say, no one can prove that you were at home that night?" Li Hui asked back.
"Comrade policeman, I was really wronged." Chen Jun shouted.
"Every suspect who entered this room said that he was wronged, and his innocence cannot be proved by loud voice."
"I'm really wronged!"
"Then let me ask you, why did your white genetic material appear at the crime scene?" Han Bin asked.
"Where is the scene you said?"
"Street Park."
"I've never been to that park at all."
Li Hui snorted: "Don't pretend, if you haven't been to the scene, how could you have your white genetic material, this thing can't be faked."
"I'm really wronged, there must be something wrong here." Chen Jun shouted.
Han Bin shook his head slightly: "White genetic material is evidence that can incriminate. If you can't explain why the genetic material appeared at the scene of the crime, no one can help you."
"I really don't know." Chen Jun cried anxiously.
…
An hour later, Han Bin and Li Hui left the interrogation room.
Zeng Ping cut to the chase: "How was the inquiry?"
"The suspect has no alibi."
"Any new clues?"
"The suspect's mouth was tight, he just said he didn't know." Li Hui sighed.
"The DNA comparison has been successful, it's useless even if he doesn't admit it." Zhao Ming said.
Han Bin thought about it seriously: "Captain Zeng, I think this case is still suspicious."
"What doubt?"
"This Chen Jun doesn't seem to be lying."
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 frightened, but there was no sign of lying.
This is not what a murderer should do.
Zeng Ping was a little surprised: "Is there any evidence?"
Han Bin shook his head, this is all his analysis.
"Han Bin, what the police pay attention to is evidence." Zeng Ping said earnestly:
"As long as Chen Jun does not have an alibi within the time of the incident and cannot explain why his genetic material appeared at the scene, his suspicion cannot be removed."
"yes."
"Okay, everyone is tired today, so let's go here first, and the trial will continue tomorrow."
Back home, Han Bin was still thinking about the case.
Micro-expression analysis error
There is still another real culprit!
With this question in mind, Han Bin slowly fell asleep.
…
next morning.
Huayuan Community, Room 1201.
After Han Bin got up, he washed up, put on clean clothes, and went downstairs to have breakfast.
Han Bin's parents also live in this building, Room 601.
Han Bin's father is Han Weidong, who is also a policeman and works at the Guang'an Police Station.
Mother Wang Huifang retired at home.
When Han Bin entered the house, he 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 smiled.
"What do you know, kid? Live and learn. I am studying national policy and actively responding to the call of the country."
"Where's my mother?"
"I went to the vegetable market to buy vegetables."
"What's for breakfast?" Han Bin yawned.
"Go and wash your hands, I'll serve you a meal."
"I still have this treatment?" Han Bin was flattered.
"Your mother said, you criminal police are busy with work, let me, a policeman, support your work more." Han Weidong snorted.
Han Bin laughed: "Mom's consciousness is still high."
"show off."
After washing his hands, Han Bin went to the restaurant. On the table were a plate of fried rice with eggs, a bowl of polenta, a small plate of pickles and beef in sauce.
"The food is good." Han Bin was also a little hungry, and took two bites of egg fried rice, as if thinking of something: "Dad, is this rice leftover from yesterday?"
"Overnight rice has less moisture and tastes better when fried." Han Weidong also cooks in his spare time.
Han Bin was thoughtful: "Overnight? Not on the same day."
"Eat slowly, there's still some in the pot." Han Weidong finished his sentence and went back to the living room to read the newspaper.
With a few pieces of sauced beef, Han Bin finished his fried rice with eggs and didn't bother to drink polenta, so he rushed to the branch office in a hurry.
He had a speculation that it might explain why the suspect's genetic material appeared at the crime scene...
