The 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 for processing.

When I returned to the office room, I saw Zeng Ping eating breakfast on the table, fried dough sticks, tea eggs, tofu brains, and pickles, which looked quite hearty.

"Zeng. ”

"Han Bin, do you want to have some breakfast?" Zeng Ping said politely.

"I've eaten it. Han Bin said.

"Yesterday, what happened to your investigation with Li Hui?" Zeng Ping said.

"I'm about to report back to you. Han Bin took out a screenshot of the video: "Chen Jun, on the evening of June 17th, I went to the Yindu foot bath shop. ”

"This cannot be regarded as an alibi, and the time of the crime was on the evening of June 18. Zeng Ping said.

"Here's another photo, in the early morning of June 18th. 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 deliberately put it at the crime scene." ”

"This man wearing gloves, at nine o'clock in the evening on June 18, left through the back door of the street park, which is a screenshot of the video. Han Bin put another photo on the table.

Zeng Ping put the three photos together, touched his chin and said, "It's really a person, it's a little interesting." ”

"I think this man with gloves is very suspicious. Han Bin said.

This can only show that he is suspicious, and if he wants to be convicted, he has to come up with direct evidence. Zeng Ping said.

"Team Zeng, two pubic hairs were also found at the scene of the crime, and I suggest that DNA testing be done on those two hairs. Han Bin said.

"The hair may not be the suspect's, it may be the victim's, and the hair may not necessarily be biologically sampled. Zeng Ping said.

"The hair is small, it's hard to spot at night, and even if it does, the suspect can't detect it, and in a sense, it's more accurate than DNA. Han Bin said.

"Okay, I'll apply. Zeng Ping said.

"The team was wise. Han Bin said with a smile.

"Don't pat me on the back. Zeng Ping scolded with a smile: "Give you and Li Hui a task to find out the identity of the gloved suspect and get his biological samples." ”

"Yes. ”

......

The technical team processed the suspect's video in high definition, captured a clear front photo, and then compared it in the database, checked it for half a day, and finally found the identity of the suspect.

Name: Li Feifan

Ethnicity: Han

Age: 25 years old

Height: 174cm

Job: Car sales

Family Status: Unmarried.

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

"Or summon him directly, pretend to be a routine questioner, and get his biological samples. Li Hui said.

"Summoned to the police station, it may be a surprise. Han Bin said.

"So what do you say?"

"Follow him and find a way to get biopsies. Han Bin said.

"Hehe, you kid still has this fetish. Li Hui said with a smile.

......

Where Li Feifan lives, not far from the 4S store, three stops away by bus.

In order to avoid being discovered, the two formed two sections, Han Bin was responsible for tracking the first half, and Li Hui was responsible for tracking the second half.

From the vicinity of Rongxin Community, Han Bin began to follow Li Feifan, Li Feifan was dressed very energetically, his hair was very confident, and he could smell a strong smell of hairspray from a distance of one or two meters.

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

Han Bin pretended to look 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 swept to some fashionably dressed young women from time to time.

When he arrived at the third station, Li Feifan got off the train, but Han Bin did not get off the train, in order not to arouse the other party's vigilance, he would sit on the ground again.

The next tracking is in charge of Li Hui.

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

Han Bin sat on the ground for one more stop, and after getting off the bus, he rushed to the vicinity of the 4S store to meet Li Hui.

From a distance, Han Bin saw Li Hui standing next to the trash can smoking, and said, "How is it?"

Li Hui smiled, carried a plastic bag, and shook it, which contained a plastic cup and straw.

"Good job. Han Bin said with a smile.

The two then returned to the police station and sent the plastic cups and straws to the technical team for inspection.

Targeted comparison, much faster.

......

The next day, in the morning.

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

"Papa......" Zeng Ping slapped his face: "Let's put down the work at hand and have a meeting." ”

"Team Zeng, the results of the DNA comparison are out?" Han Bin said.

"Coming out?"

One of the pubic hairs was extracted from the DNA sample, and after some comparison, it matched Li Feifan's DNA. Zeng Ping said.

"In this way, Li Feifan is very suspicious, he happened to be in the street park during the time of the crime. Tian Li said.

More critically, it is possible that he obtained Chen Jun's white genetic material, in an attempt to clear his suspicion by framing Chen Jun. Han Bin said.

"Han Bin, you kid has made meritorious service again. Zeng Ping said with a smile.

"Thanks to your support. Han Bin said.

"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 tools of the crime. Zeng Ping said.

"Team Zeng, apply for a search warrant. ”

"Tian Li, you go and apply for a search warrant and an arrest warrant, and the others will follow me to set up a charge. Zeng Ping commanded.

"Yes. ”

......

Rongxin Community, Li Feifan's house.

Li Feifan rested today, slept until nine o'clock in the morning, was still too lazy to get up, ate a few biscuits, and lay on the bed playing with his mobile phone.

By noon, take it out early.

"Knock knock......" There was a knock on the door.

"Who?"

"I'm downstairs, and your toilet is leaking, and it's clouding our roof. A man said.

"No way, we don't have water in the toilet. Li Feifan said.

"If you don't believe me, you come with me downstairs to have a look. ”

"Squeak......" Li Feifan opened the door and didn't speak yet.

I saw several men rushing in, led by a man who said, "We are the police." ”

"What are you doing at my house?"

"We suspect that you are involved in a rape case, and this is a search warrant. Han Bin said.

"Is there any misunderstanding here?" Li Feifan said.

"We are here to investigate this time to return your innocence, and I hope you can cooperate. Han Bin said.

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

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

"Where were you on the night of June 18?" Zeng said.

"After all this time, I can't remember. Li Feifan said.

"Then let me remind you, you went to Street Park. Zeng Ping said.

"Oh, I remember, some time ago, I seem to have heard about a rape case in the street park. Li Feifan seemed to have just recalled, and said:

"However, the fact that there are more people going to the street park does not mean that I have anything to do with the case. ”

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

"This can't be!" Li Feifan said in surprise.

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

Judging from the current facts of the case, Li Feifan has a certain amount of anti-reconnaissance ability, and if he wants to be convicted, he has to rely on evidence.

After a while, Tian Li walked over: "No crime tools were 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: "I'll just say it, I have nothing to do with this case, I am innocent." ”

You said this sentence a little earlier. Han Bin said.
