"Team Zhao, the deceased is a young woman named Lin Qi. She was only 25 years old, unmarried, and was an employee of an advertising company."

"Yesterday she made an appointment with her colleagues to go shopping today, but when the agreed time came, she never went out and didn't answer her phone calls. So her colleagues came to her rented apartment to look for her."

"But after knocking for a long time, the door didn't open, and I could hear the ringing in her room when she was on the phone."

"Worried about something, her colleagues came to the property management company and explained the situation. After a group of people opened the door, they found that she had died at home."

"After we arrived, we immediately conducted a preliminary investigation on the scene. It can be seen at the scene that there were signs of a fight before the death of the deceased. The deceased's face was bruised and his eyeballs were protruding. After the preliminary inference of the forensic doctor, the cause of death was mechanical asphyxiation due to someone grabbing his throat. The time of death was probably around [-] a.m. last night."

Zhao Donglai turned on the loudspeaker, so Luo Fei also heard what Liao Xingyu said.

But when he heard the name of the deceased, he felt a familiar feeling inexplicably.

It seems that I have heard this name somewhere, but I can't remember it at the moment.

"It will take a while before we get here. You should visit the nearby residents immediately, and recruit a team of people to investigate Lin Qi's interpersonal relationships. By the way, remember to copy all the surveillance cameras around the apartment."

After making some quick arrangements, Zhao Donglai hung up the phone.

Half an hour later, the two finally arrived at the scene.

The apartment where Lin Qi rented has been cordoned off. Liao Xingyu and others are not here. Only Zhao Tian and a few members of the technical squadron are still surveying the scene.

Zhao Donglai and Luo Fei picked up the shoe covers next to them and put them on before walking in.

Seeing him come in, Zhao Tian shouted, "Captain Zhao, you're here."

"Well, what have you discovered now?"

"We extracted several adult male shoe prints at the scene, and also extracted several fingerprints near the deceased. However, we need to go back and compare them to know whether they were left by the deceased or the murderer."

"In addition, we also extracted some blood stains from the deceased's fingernails. It is speculated that the deceased struggled with the murderer before his death and scratched the other party."

Zheng Donglai perked up and said, "This is a big discovery. Let's quickly extract the DNA and compare it with the ones in the sample library to see if there are any clues."

After Zhao Tian agreed, he did not disturb them, but took Luo Fei around the scene.

This apartment has a deep well layout and was built into a small third floor.

The first floor is for daily activities and cooking, the second floor is for bedrooms and study, and the third floor is used by Lin Qi to store sundries.

The place where Lin Qi died was next to the sofa on the first floor. Her body has been removed, but the books and tea cups scattered around the body are still in place. It can be seen that the deceased must have struggled and resisted with the other party before her death. move.

After walking around and not finding much, Zhao Donglai took Luo Fei out.

When he came outside the door, he was still taking off his shoe covers when he saw Luo Fei turned around and looked around, then walked straight towards the corridor to the side.

His heart moved and he hurriedly followed, "Luo Fei, did you discover anything?"

At this time, Luo Fei opened the door of the power distribution room, sniffed the air, and showed a knowing expression.

"Captain Zhao, I smelled the same odor residue as the one at the death scene of the deceased, and based on the concentration of the leak, I felt that the other party should have been here for a long time, so I speculated that this was probably the murderer. left."

Zhao Donglai was overjoyed, "Let's see if we can find the murderer's final whereabouts based on this smell."

"Okay, let me try."

Luo Fei said, immediately followed the smell and took the elevator, scared to the first floor.

After walking out of the apartment, Zhao Donglai followed him straight across the road to the river embankment opposite.

Luo Fei stood in front of the stone guardrail, looking at the bottomless river water below, and frowned.

"What's wrong, Luo Fei?"

"Captain Zhao, the opponent's aura suddenly disappeared here."

"Disappeared? You mean he swam across the river and left?"

Zhao Donglai was full of surprise. It was impossible for the murderer to jump into the river, right?But it's not impossible.

Luo Fei was obviously not sure, "I'm not sure about this yet."

After the two were silent for a while, Zhao Donglai said, "Then let's go back first. I see that the row opposite is full of merchants. Maybe one of them was captured by the surveillance camera. Let's go back and check the surveillance video."

"it is good."

The two went straight back to the police force.

At this time, everyone who went out to visit also came back one after another.

Liao Xingyu and the others integrated the clues and immediately came to Zhao Donglai to report.

"Team Zhao, we visited the households around Lin Qi. One of the two families said that around [-] o'clock last night, they could indeed hear the sound of quarrels coming from Lin Qi's house. According to their description, the quarrel was not only Lin Qi's own voice, and a young male.”

"We interviewed colleagues at Lin Qi's company, and they all said that Lin Qi was very popular in the company and had no enemies. However, it is said that Lin Qi also has a suitor named Zhou Fangping."

"Furthermore, through the surveillance downstairs of Lin Qi's apartment, we found that this person happened to leave the apartment at [-]:[-] last night. I called him as soon as possible to inform him to come and cooperate with the investigation. He said he would Come right away."

"Okay, very good. Have you notified Lin Qi's parents?"

"We have been notified. They are all in their hometown in Ningjiang County. It will take some time to come over."

"Then notify me immediately when Zhou Fangping arrives."

After a while, Zhou Fangping arrived.

Zhou Fangping, 27 years old, with fairly good facial features, currently works as a salesperson in a real estate company.

Liao Xingyu took him to the recording room and asked someone to notify Zhao Donglai.

After receiving the news, Zhao Donglai hurriedly called Luo Fei over.

Just standing outside and taking a quick look, Luo Fei shook his head and said, "It's not him."

Not only was the smell wrong, there was no black aura about him.

Zhao Donglai couldn't help but be a little disappointed.

But after thinking about it, few people dare to come to the police station themselves after killing someone.

After all, people like Lao Wu are in the minority.

Although Zhou Fangping is not the murderer, necessary inquiries are still needed.

Zhao Donglai sat down with Liao Xingyu.

Subsequent inquiries revealed that Zhou Fangping had indeed gone to see Lin Qi last night.

They met on a blind date in March this year, and he fell in love with Lin Qi at first sight.But Lin Qi didn't seem to like him very much. Zhou Fangping had been chasing her for several months, but she was still very cold.

Zhou Fangping was also anxious. He just wanted to go to her and explain things to her last night.

During the conversation, Lin Qi said that she had no plans to get married because of her previous experiences, and asked Zhou Fangping not to waste time on her.

Zhou Fangping was a little angry. You didn't plan to get married, so why did you go on a blind date?

Feeling that he had been fooled, he quarreled with Lin Qi angrily, and the two broke up unhappy.

"Comrade police, I was just too angry, so I had a few quarrels with her, but I didn't kill anyone. She was really fine when I left. I can swear..."

When Zhou Fangping learned that Lin Qi was dead, he was a little panicked, fearing that the police would regard him as the murderer.

"Don't worry, we are just making routine inquiries and we have no intention of doubting you."

Normally, someone like Zhou Fangping would definitely be regarded as the number one suspect, but because of Luo Fei, his suspicion was cleared.

Zhao Donglai comforted him and then asked, "You just said that Lin Qi said she didn't want to get married because of her previous experience. Do you know what happened?"

"It seems that she was cheated on by her ex-boyfriend, but I don't know the specific situation. I just heard the introducer casually say it."

"Okay we understand."

Then Zhao Donglai asked a few more questions, told the other party to cooperate with the investigation at any time, and then let him go.

After Zhou Fangping left, Zhao Donglai called everyone to the conference room for a meeting to discuss the case.

"Based on the information currently available, the quarrel that the deceased's neighbors heard last night should be Zhou Fangping."

"According to his statement, it can be known that the murderer should have committed the murder after he left, but when he went, there was no one else in the deceased's home."

"In addition, Luo Fei found the smell of the suspected murderer in the power distribution room of Lin Qi's building. It can be inferred that the murderer should have been hiding there until Zhou Fangping left before entering the deceased's room."

"There are no signs of damage to the door lock of the deceased's room. It is inferred that the deceased should have opened the door for the other party."

Zhao Donglai paused and then said, "At one o'clock in the morning, under what circumstances will a woman who lives alone open the door to the other party?"

"That must be an acquaintance. If it were a stranger, the deceased would definitely not be able to open the door." Liao Xingyu answered quickly.

"Yes, that means the murderer is probably someone familiar to the deceased... After you come down, you should immediately conduct a careful investigation of the deceased's interpersonal relationships."

"Also, check the surveillance video from last night immediately to see who else left the apartment after Zhou Fangping left."

"Especially pay attention to the surveillance of the row of businesses downstairs in the apartment. Luo Fei tracked the other party's scent, and finally lost the trace on the river embankment opposite the apartment."

After finishing speaking, Zhao Donglai looked at Zhao Tian again, "Tell me the results of your investigation of the site."

"Team Zhao, through analysis of several shoe prints extracted from the deceased's home, they belong to two men, one of whom is Zhou Fangping."

"The other one should be the murderer. Through analysis, the murderer is an adult male who wears size 42 shoes, is 175cm tall, and weighs between 120cm."

"Very good. When we investigate the deceased's interpersonal relationship later, we will focus on this aspect. Now go down and get busy."

Everyone walked out of the conference room one after another.

Several group leaders gathered together and had a brief discussion.

In the end, it was decided that one group would stay in the team to check the surveillance, the second group would check the address book and chat history of the deceased's mobile phone, and the third and fourth groups would be responsible for visiting the deceased's interpersonal relationships.

About half an hour later, Lin Qi's parents also arrived.

Lin Qi is the only daughter in the family. The two elderly people were obviously severely hit. When they entered the door, they kept asking if the police had made a mistake.

It wasn't until Zhao Tian led them to see Lin Qi's body that they finally had to accept the bad news and cried to death in the technical office.

And here Luo Fei checked the surveillance and found that great progress had been made.

First, they saw on the surveillance camera downstairs in the apartment that about 10 minutes after Zhou Fangping left, a man in a black coat hurriedly ran out of the apartment.
It's June weather, and wearing a coat at this time would be unusual.

Luo Fei and others immediately analyzed the video of him repeatedly. Judging from the body shape, the height and appearance of the other party were consistent with Zhao Tian's description, and they could basically conclude that this person was the murderer.

It's just that the other party had his back to the surveillance camera the whole time, so they couldn't see the other party's face at all.

Luo Fei quickly moved the surveillance camera forward, and finally saw a man wearing the same coat walking into the apartment at three o'clock yesterday afternoon.

It's a pity that the other person was consciously avoiding surveillance. Not only did he keep his head down, he also covered his head with the hood of his coat, so they still couldn't see his appearance.

Luo Fei then called up the surveillance cameras of several nearby shops, and sure enough, he saw the man walking straight to the embankment on the other side of the road after leaving the apartment last night.

The other party stood in front of the guardrail for about ten minutes. Suddenly he climbed up the guardrail and jumped, and then his figure completely disappeared from the surveillance camera.

After watching the surveillance video, Zhang Wei couldn't help but guess, "Team leader, do you think this guy knew he couldn't escape the law, so he committed suicide by jumping into the river?"

Luo Fei frowned, "It's hard to say, this possibility is indeed very high... Then you should immediately go to the other side of the river to investigate the surrounding surveillance to see if there is any footage of the other party coming ashore, and I will report the situation to Team Zhao."

"Okay, let's go right away."

A group of people hurried away, and Luo Fei found Zhao Donglai and told them what they had discovered.

At this moment, Zhao Donglai was more inclined to believe that the murderer committed suicide out of fear of crime. He said, "Then I will immediately notify the salvage team and ask them to salvage the river sections along the way."

After that, he added, "The parents of the deceased are here. Come with me to make inquiries."

"it is good."

At this time, Lin Qi's parents finally calmed down a bit and were sitting in the recording room weeping silently. Zhao Tian was worried that something would happen to the two of them, so she poured them two glasses of water and sat beside them to keep them company.

After seeing Zhao Donglai come in, she said something and went out.

At this time, Lin Qi's mother Tian Yunfen cried, "Comrade police, my daughter is so pitiful. She is still so young. Who is so heartless and murderous? I beg you to find the murderer and avenge her!"

"Family members, please rest assured that these are our responsibilities. We will definitely catch the murderer as soon as possible and give your daughter justice."

After appeasing the couple, Zhao Donglai immediately interrogated the couple in a routine manner.

"I heard from your daughter's blind date that your daughter once had a failed relationship? Can you tell us about it?"

By searching Lin Qi's room, the police found that her family's finances were not lost, and there were no signs of disturbance in the house. Therefore, everyone is more inclined to believe that this was a vendetta or love killing.

So as soon as he opened his mouth, Zhao Donglai directly asked this question.

When Tian Yunfen heard this, a hint of anger suddenly appeared in his sad expression.

"This is all the fault of that scumbag Zhou Qiang. If he hadn't been messing around with a married woman..."

"Zhou Qiang?" Luo Fei exclaimed, finally knowing why he felt that the name Lin Qi was familiar to him.
