The next morning.
Han Bin went to the police station early in the morning and handed over the backup of the video to the forensics team.
When he returned to the office, he saw Zeng Ping having breakfast on the table. There were fried dough sticks, tea eggs, tofu pudding, and pickled vegetables. It looked quite sumptuous.
"Captain Zeng."
"Han Bin, do you want some?" Zeng Ping asked politely.
"I've eaten."
Zeng Ping ate as he asked, "How did your investigation with Li Hui go yesterday?"
"I was about to report to you." Han Bin took out a screenshot of the video. "Chen Jun went to the Yindu Foot Bath on the night of June 17th."
"This can't be used as an alibi. The crime was committed on the night of June 18th."
"There's another photo on the morning of June 18th," Han Bin said.
Zeng Ping glanced at it and immediately understood. "You suspect that someone picked up Chen Jun's genetic material and deliberately placed it at the crime scene."
"This gloved person left from the back door of the park at nine o 'clock on the night of June 18th. This is a screenshot of the video." Han Bin put another photo on the table.
Zeng Ping put the three photos together and touched his chin. "It's really the same person. Interesting."
Han Bin pointed at the photo. "I think this gloved person is very suspicious."
"This can only mean that he is suspicious. If we want to conclude the case, we have to show direct evidence."
"Captain Zeng, two strands of pubic hair were also found at the crime scene. I suggest we do a DNA test on those two strands of hair."
"The hair might not be the suspect's. It could also be the victim's, and the hair might not be able to be used for biological analysis."
"The hair is very small and hard to find at night. Even if it falls, the suspect won't notice it. In a sense, it's more accurate than DNA," Han Bin said.
Zeng Ping hesitated for a moment. "Alright, I'll apply for it."
"Captain Zeng is wise." Han Bin smiled.
"Don't flatter me." Zeng Ping jokingly scolded, "I'll give you and Li Hui a mission. Find out the identity of the suspect in the glove and get his biological samples."
"Yes."
…
The technical team processed the suspect's video in high definition and took a clear frontal photo. Then, they compared it with the database. After checking for half a day, they finally found the suspect's identity.
Name: Li Feifan
Race: Han
Age: 25
Height: 174cm
Job: Car Sales
Family Status: Unmarried.
Address: Rongxin District, Granite Road, Qingdao City, 4-2003.
"Why don't we just summon him and pretend to be a routine interrogation to get his biological data?" Li Hui suggested.
"Summoning him to the police station might inadvertently alert the enemy," Han Bin said.
"Then what do you suggest we do?"
"Follow him and find a way to get biological samples."
"Hehe, kid, you have such a hobby." Li Hui laughed.
…
The place where Li Feifan lived wasn't far from the 4S store. It was only three stops away on the bus.
In order to avoid being discovered, the two split up. Han Bin was responsible for the first half, and Li Hui was responsible for the second half.
Han Bin began to follow Li Feifan from the Rongxin District. Li Feifan was well dressed, and his hair was styled confidently. He could smell the strong smell of hair gel from a meter or two away.
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 him to avoid alerting the other party.
The bus arrived, and the two got on one after the other.
After Li Feifan got on the bus, his eyes glanced at some fashionable young women from time to time.
At the third stop, Li Feifan got off, but Han Bin didn't. In order not to alert the other party, he would sit at the next stop.
Li Hui was responsible for the follow-up.
And their target was the soy milk cup and straw in Li Feifan's hand.
Han Bin sat at the next stop. After getting off, he rushed to the 4S store and met up with Li Hui.
From afar, Han Bin saw Li Hui smoking next to the trash can. "How is it?"
Li Hui chuckled and shook a plastic bag in his hand. There was a plastic cup and a straw inside.
"Good job."
The two returned to the police station and sent the plastic cup and straw to the technical team for examination.
A targeted comparison would be much faster.
…
The next morning.
Zeng Ping returned to the office with the test report.
"Clap, clap …" Zeng Ping clapped his hands. "Everyone, stop what you're doing and have a meeting."
"Captain Zeng, are the DNA results out?"
"Yes." Zeng Ping handed the test report to everyone.
"DNA was extracted from one of the pubic hairs. After some comparison, it matches with Li Feifan's DNA."
"In that case, Li Feifan is very suspicious. He happened to be at the park in the middle of the street during the time of the crime," Tian Li said.
"More importantly, he may have obtained Chen Jun's white genetic material and tried to frame Chen Jun to clear his name," Han Bin added.
Zeng Ping smiled. "Han Bin, you've done a good job again."
"It's all thanks to your support."
"This case has been dragged on for a long time. We must solve 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, apply for a search warrant and arrest warrant. The rest of you, follow me," Zeng Ping ordered.
"Yes."
…
Rong Xin District, Li Feifan's house.
Li Feifan had a rest day. He slept until nine in the morning, but he was still too lazy to get up. He ate a few biscuits and played with his mobile phone in bed.
At noon, he ordered takeout for breakfast.
"Knock, knock, knock …" There was a knock on the door.
"Who is it?"
"I'm from downstairs. Your toilet is leaking, and our roof is covered," a man replied.
"That can't be. Our toilet doesn't have any water," Li Feifan said.
"If you don't believe me, follow me downstairs."
"Creak …" Li Feifan opened the door, but before he could say anything, a few men rushed in.
A few men rushed in. The leader was a middle-aged man. He flashed his police badge and said, "We are the police."
"What are you doing at my house?"
"We suspect that you are related to a rape case. This is the search warrant," Han Bin said.
Li Feifan looked a little innocent. "Is there some misunderstanding here?"
"The purpose of our investigation this time is to prove your innocence. I hope you can cooperate."
Zeng Ping waved his hand. "Search carefully."
"I didn't do anything. How could I be related to this case?" Li Feifan argued.
Zeng Ping stared at him. "Li Feifan, where were you on the night of June 18th?"
"It's been so long. I can't remember."
"Then let me remind you. You went to Street Center Park."
"Oh, I remember. Some time ago, I heard that there was a rape case in Street Center Park." Li Feifan seemed to have just recalled.
"However, many people went to Street Center Park. It doesn't mean that I am related to the case."
"We found your DNA at the scene," Zeng Ping said.
Li Feifan was surprised. "That's impossible!"
"Hehe, don't be too confident." Zeng Ping smiled and didn't say anything else.
Judging from the current case, Li Feifan had a certain anti-investigation ability. If they wanted to convict him, they would have to rely on evidence.
After a while, Tian Li walked over. "We didn't find any tools in the master bedroom."
Zhao Ming also shook his head. "We didn't find it in the bathroom either."
Li Hui said, "We didn't find it in the kitchen either."
Hearing this, Li Feifan smiled. "I told you, I have nothing to do with this case. I am innocent."
Han Bin snorted. "It's too early for you to say that."
