Detective from The Future

The next morning.

Han Bin went to the police early in the morning and handed the backup of the video to the technical team for processing.

Back in the office room, I saw Zeng Ping eating breakfast on the table, fried dough sticks, tea eggs, tofu brains, and pickles. They looked very rich.

"Team Zeng."

"Han Bin, do you want something?" Zeng Ping said politely.

"I have already eaten."

Zeng Ping asked while eating, "How did you investigate with Li Hui yesterday?"

"I am preparing to report to you." Han Bin took out a screenshot of the video: "Chen Jun, on the night of June 17th, I have been to the Yindu foot bath shop."

"This can't be used as an alibi. The time for the crime was the evening of June 18."

"Here's another photo from the early morning of June 18th." Han Bin said.

Zeng Ping took a look and immediately figured it out: "You suspect that someone has picked up Chen Jun's genetic material and deliberately put it on the crime scene."

"This man wearing gloves, leaving from the back door of Street Heart Park at 9 p.m. on June 18th, this is a video screenshot." Han Bin put another photo on the table.

Zeng Ping put the three photos together and touched his chin: "I'm really alone, it's kind of interesting."

Han Bin pointed to the photo: "I think this man wearing gloves is very suspicious."

"This can only show that he is suspicious. If he wants to conclude the case, he has to show direct evidence."

"Team Zeng, two pubic hairs were also found at the scene of the crime. I suggest DNA testing for those two hairs."

"The hair may not belong to the suspect or the victim, and the hair may not necessarily be able to extract biological samples."

"The hair is so small that it is difficult to find at night. Even if it falls, the suspect will not notice it. In a sense, it is more accurate than DNA." Han Bin said.

Zeng Ping hesitated for a moment: "Okay, I will apply."

"Zeng team is wise." Han Bin smiled.

"Don't shoot me flattering." Zeng Ping scolded with a smile: "Give you and Li Hui a task to find out the identity of the suspect wearing gloves, and get his biological inspection materials."

"Yes."

...

The technical team processed the video of the suspect in high-definition, intercepted a clear frontal photo, and compared it in the database. After checking for half a day, the suspect's identity was finally found.

Name: Li Feifan

Nationality: Han

Age: 25 years old

Height: 174cm

Work: car sales

Family status: unmarried.

Address: Qindao City, Huagang Road, Rongxin Community, 4-2003.

"Why don't you just summon him, pretend to ask routinely, and get his biological inspection materials." Li Hui suggested.

"Summoned to the police station, you may be stunned." Han Bin said.

"Then what do you say?"

"Follow him and find a way to obtain biological inspection materials."

"Hey, your kid still has this habit." Li Hui smiled.

...

The place where Li Feifan lives is not far from the 4S shop, and it is only three stops by bus.

In order to avoid being spotted by tracking, the two of them split into two sections, with Han Bin following the first half and Li Hui following the second half.

From near the Rongxin community, Han Bin began to follow Li Feifan. Li Feifan dressed up very vigorously and took care of his hair confidently. One or two meters away, he could smell a strong smell of hair gel.

After he arrived at the bus stop, he bought a pancake and a cup of soy milk.

Han Bin pretended to look at the phone, and then glanced at it, so as not to arouse the other's alarm.

The bus came, and the two got on the bus one after another.

After Li Feifan got in the car, his eyes swept from time to time to some young women in fashionable clothes.

At the third stop, Li Feifan got off the car, but Han Bin didn't get off the car. In order not to alert the other party, he would take another stop.

Li Hui will be responsible for the following follow-up.

And their goal is the soy milk cup and straw in Li Feifan's hand.

Han Bin took more than one stop, got off the bus, rushed to the vicinity of the 4S shop, and met with Li Hui.

A long way away, Han Bin saw Li Hui standing beside the trash can and smoking: "How about?"

Li Hui smiled, carrying a plastic bag and shaking it, which contained a plastic cup and straw.

"Good job."

The two immediately returned to the police station and sent the plastic cup and straw to the technical team for inspection.

Targeted comparison is much faster.

...

The next day, in the morning.

Zeng Ping took the inspection report and returned to the office.

"Papa..." Zeng Ping slapped his hands: "Everyone, let go of your work and have a meeting."

"Team Zeng, did the DNA comparison result come out?"

"It's coming out." Zeng Ping handed the inspection report to everyone:

"One of the pubic i hairs was extracted with DNA samples, and after some comparisons, it was consistent with Li Feifan's DNA."

"So, Li Feifan's suspicion is very high. He happened to be in the street park at the time of the crime." Tian Li said.

"More importantly, he may have obtained Chen Jun's white genetic material in an attempt to remove his suspicion by framing Chen Jun." Han Bin added.

Zeng Ping smiled: "Han Bin, your kid has done a good job again."

"Thanks to your support."

"This case has been delayed for a long time. We must understand it as soon as possible, otherwise, the suspect will most likely deal with the criminal tool."

"Team Zeng, apply for a search warrant."

"Tian Li, apply for a search warrant and an arrest warrant, and other people will follow me to arbitrate." Zeng Ping ordered.

"Yes."

...

Rongxin Community, Li Feifan's home.

Li Feifan took a rest today and slept until nine o'clock in the morning. He still didn't bother to get up, ate a few biscuits, and lay on the bed and played on the phone.

At noon, take out early.

"Boom boom boom..." A knock on the door sounded.

"Who is it?"

"I'm downstairs, your toilet is leaking, and our roof is overcast." A man responded.

"No, there is no water in our toilet." Li Feifan said.

"Don't believe me, follow me downstairs and have a look."

"Crack..." Li Feifan opened the door, before speaking.

Several men rushed in. The leader was a middle-aged man who showed his police officer ID: "We are the police."

"What are you doing at my house?"

"We suspect that you are related to a **** case. This is a search warrant." Han Bin said.

Li Feifan looked a little innocent: "Is there any misunderstanding here?"

"We are here to investigate this time to restore your innocence. I hope you can cooperate."

Zeng Ping waved his hand: "Search, be careful."

"I haven't done anything, how could it be related to this kind of case." Li Feifan defended.

Zeng Ping stared at each other: "Li Feifan, where were you on the night of June 18th?"

"After so long, I can't remember."

"Then let me remind you, you went to the street park."

"Oh, I remember. Some time ago, I heard that there was a **** case in Street Heart Park." Li Feifan seemed to recall:

"However, there are more people going to the street park, which does not mean that I am related to the case."

"We were at the scene and found your DNA sample." Zeng Ping said.

Li Feifan showed a surprised look: "This is impossible!"

"Hehe, don't be overconfident." Zeng Ping smiled, and said no more.

Judging from the current case, Li Feifan has a certain degree of anti-reconnaissance ability. If he wants to convict him, he must rely on evidence.

After a while, Tian Li came over: "The master bedroom did not find any tools of crime."

Zhao Ming also shook his head: "There is no bathroom either."

Li Hui said, "There is no kitchen either."

Hearing this, Li Feifan smiled: "Let me just say it, I have nothing to do with this case, I am innocent."

Han Bin snorted: "This sentence, you said it earlier."
