next morning.
Han Bin went to the police force early in the morning and handed over the backup of the video to the technical team.
Back in the office, I saw Zeng Ping eating breakfast on the table, fried dough sticks, tea eggs, tofu brain, pickles, it looked quite rich.
"Team Zeng."
"Han Bin, would you like some?" Zeng Ping asked politely.
"I have already eaten."
While eating, Zeng Ping asked, "Yesterday, how did your investigation with Li Hui go?"
"I'm about to report to you." Han Bin took out a screenshot of the video: "Chen Jun, on the night of June 17th, I went to the Yindu Foot Bath Shop."
"This can't be taken as an alibi. The crime was committed on the night of June 18."
"Here's another photo from the early morning of June 18," Han Bin said.
Zeng Ping glanced at it and immediately figured it out: "You suspect that someone picked up Chen Jun's genetic material and put it at the crime scene on purpose."
"This gloved person left from the back door of the park in the middle of the street at 9:00 p.m. on June 18th. This is a screenshot of the video." Han Bin put another photo on the table.
Zeng Ping put the three photos together, touched his chin: "It's really a person, it's interesting."
Han Bin pointed to the photo: "I think the person wearing gloves is very suspicious."
"This only shows that he is suspected. If he wants to settle the case, he has to produce direct evidence."
"Team Zeng, two pubic hairs were also found at the scene of the crime. I suggest doing a DNA test on those two hairs."
"The hair may not necessarily belong to the suspect, but may also belong to the victim, and the hair may not necessarily be used to extract biological samples."
"The hair is so small that it's hard to find it at night. Even if it falls off, the suspect won't be able to notice it. In a sense, it's more accurate than DNA," Han Bin said.
Zeng Ping hesitated for a moment: "Okay, I will apply."
"Captain Zeng is wise." Han Bin laughed.
"Stop flattering me." Zeng Ping cursed with a smile, "I'll give you and Li Hui a mission to find out the identity of the suspect wearing gloves and obtain his biological samples."
"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 half a day of checking, the suspect's identity was finally found.
Name: Li Feifan
Nationality: Han
Age: 25 years old
Height: 174cm
Job: Car Sales
Family status: single.
Address: Qindao City, Huagang Road, Rongxin Community, 4-2003.
"Why don't you summon him directly, pretend to be a routine inquiry, and get his biological samples." Li Hui suggested.
"Summoning to the police station may scare the snake away." Han Bin said.
"Then what do you say?"
"Follow him and find a way to obtain biological samples."
"Hey, you still have this habit." Li Hui laughed.
…
The place where Li Feifan lived was not far from the 4S store, and it was only three stops by bus.
In order to avoid being discovered by the stalking, the two separated into two sections, Han Bin was responsible for tracking the first half, and Li Hui was responsible for the second half.
Han Bin began to follow Li Feifan from the vicinity of Rongxin Community. Li Feifan dressed up very energetically and did his hair confidently. He could smell a strong smell of hairspray one or two meters away.
After he arrived at the bus station, he bought a pancake and a cup of soy milk.
Han Bin pretended to be looking at his phone, and then glanced at it, so as not to arouse the other party's vigilance.
The bus came, and the two got on the bus one after the other.
After Li Feifan got into the car, his eyes flicked to some fashionable young women from time to time.
At the third stop, Li Feifan got off the car, but Han Bin did not get off. In order not to arouse the other party's vigilance, he would sit for another stop.
Li Hui will be in charge of the follow-up.
And their target was the soy milk cup and straw in Li Feifan's hand.
Han Bin sat for one more stop, got out of the car, and rushed to the vicinity of the 4S shop to meet Li Hui.
From a long distance, Han Bin saw Li Hui standing beside the trash can smoking a cigarette: "How is it?"
Li Hui smiled, and shook a plastic bag, which contained a plastic cup and a straw.
"Good job."
The two then 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, morning.
Zeng Ping returned to the office with the inspection report.
"Papa..." Zeng Ping slapped his hands, "Everyone put down the work at hand and have a meeting."
"Team Zeng, the DNA comparison result is out?"
"It's out." Zeng Ping handed the inspection report to everyone:
"A DNA sample was extracted from one of the pubic hairs, and after some comparison, it matched Li Feifan's DNA."
"So, Li Feifan is very suspicious. He happened to be in the middle of the street park at the time when the crime happened." Tian Li said.
"More importantly, he may have obtained Chen Jun's white genetic material in an attempt to clear himself of suspicion by framing Chen Jun." Han Bin added.
Zeng Ping smiled: "Han Bin, you've done some meritorious service again."
"Thanks for your support."
"This case has dragged on for a long time, we must understand it as soon as possible, otherwise, the suspect is likely to dispose of the crime tools."
"Captain Zeng, apply for a search warrant."
"Tian Li, go and apply for a search warrant and arrest warrant, and the others will follow me to make arrests," Zeng Ping ordered.
"yes."
…
Rongxin Community, Li Feifan's home.
Li Feifan had a rest today, slept until 9:00 am, still too lazy to get up, ate a few biscuits, and lay on the bed playing with his mobile phone.
At noon, take out early.
"Dong dong dong..." There was a knock on the door.
"Who is it?"
"I'm downstairs, your toilet is leaking, and it's clouding our roof." A man responded.
"No way, there is no stagnant water in our toilet." Li Feifan said.
"If you don't believe me, follow me downstairs."
"Crackling..." Li Feifan opened the door, before he could speak.
Several men rushed in, and the leader was a middle-aged man who showed his police ID: "We are the police."
"What are you doing at my house?"
"We suspect that you are related to a rape case. This is a search warrant." Han Bin said.
Li Feifan looked a little innocent: "Is there some misunderstanding here?"
"We came to investigate this time just to repay your innocence. I hope you can cooperate."
Zeng Ping waved his hand: "Search, be careful."
"I have never done anything, how could it be related to this kind of case." Li Feifan defended.
Zeng Ping stared at the other party: "Li Feifan, where were you on the night of June 18?"
"It's been so long, I can't remember."
"Then let me remind you, you went to the park in the middle of the street."
"Oh, I remembered. Some time ago, I heard that there was a rape case in a park in the middle of the street." Li Feifan seemed to have just recalled:
"However, the fact that there are more people going to the park in the middle of the street 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 didn't say any more.
Judging from the current case, Li Feifan has certain anti-reconnaissance capabilities, and if he wants to convict him, he still has to rely on evidence.
After a while, Tian Li came over: "No tool was found in the master bedroom."
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, I have nothing to do with this case, I am innocent."
Han Bin snorted: "You said this sentence a little earlier."
