Detective: From the Police Academy

Chapter 186 Who is the murderer?
The wind blew in from outside the terrace and balcony, and the fluttering white curtains looked like white ghosts in the dark night.

Luo Rui felt a chill in his heart and couldn't help shivering.

Qiao Dahai sat quietly in the wheelchair, his head tilted back, his long neck, his eyes wide open, as if he was dying with his eyes open.

He was not afraid of seeing dead people, but when he saw the old man die, Luo Rui was still a little panicked.

In particular, the skin of the corpse was translucent white, and purple-red corpse spots had appeared all over its body. It looked truly hideous and terrifying.

He swallowed, then quickly covered his nose and walked along the corner of the bedroom to the living room.

This is a three-bedroom apartment, and the living room is so full of garbage that there is literally no place to step.

Especially on the coffee table and the sofa, there were dozens of buckets of leftover instant noodles and a pile of empty beer bottles, some of which were full of cigarette butts.

The bedroom and kitchen were not much better, with dirty clothes and unwashed socks everywhere. In addition to the stench of corpses, the house also had a disgusting sour smell.

Luo Rui opened the refrigerator and found it was empty.

This is Qiao Jun’s home, a dead sea of ​​garbage where a 300-pound otaku and his grandfather live.

There are three bedrooms. Except for Qiao Jun and Qiao Dahai who each live in one, the other one is empty and the situation inside is relatively better.

Luo Rui walked in and took a look, and found that the room was tidy, like the room where Qiao Jun's parents lived when they were alive.

At this time, there was a fierce knock on the door, and Cai Xiaojing shouted from outside: "Luo Rui, how is it? Are you okay?"

Luo Rui hurried to the entrance and opened the door.

He saw that Cai Xiaojing had taken out her gun, and the neighbor had disappeared.

Luo Rui exhaled out the door and said, "The person is dead!"

Cai Xiaojing frowned, walked into the house cautiously, then stood at the bedroom door and looked inside.

She could only see Qiao Dahai's back.

"What happened? Was it the murderer who did it?"

Luo Rui nodded: "It should be. Qiao Dahai was trapped in a wheelchair and his mouth was sealed with tape, but the cause of death is still unclear. I have to trouble Director Zhao and his son again."

Cai Xiaojing nodded, walked aside, and called the forensic and technical investigation departments.

Taking advantage of this time, Luo Rui stood in the living room and looked around. He didn't dare to move around randomly for fear of disrupting the scene.

Unable to see anything strange, he and Cai Xiaojing retreated back to the entrance.

Zhao Chunlai and Zhao Ming arrived very quickly, and a large group of people went upstairs, crowding the narrow corridor.

Zhao Chunlai was in poor spirits, holding a thermos cup in his hand, and the forensic investigation box was carried by two police officers.

Seeing Luo Rui, he blinked and said, "Luo Rui, please solve this case quickly. I thought I could just fish and grow flowers until I retire, but I didn't expect that I would be running around like animals with you guys these days, with people dying here and there. You guys are trying to tire me to death."

Luo Rui didn't dare to talk back to Zhao Chunlai's dissatisfaction, and nodded quickly: "Yes, the murderer has already revealed his true colors."

Zhao Chunlai nodded and glanced at Zhao Ming who was standing next to him: "I'm talking to you. You only slept for three hours in two days and two nights. You have to be busy here for another day or two. Now that the trace inspection is done, go home and have some sleep!"

Zhao Ming didn't look at his father. He sorted his equipment and answered, "I know."

Unexpectedly, Zhao Chunlai cursed: "You know nothing, your wife even called me! Let me tell you, besides work, there is also family!"

Zhao Chunlai did not answer this time because there was no blood at the scene and it was not an ordinary crime scene, so he went in without wearing protective clothing.

Zhao Ming's two apprentices followed behind him, placing number plates under his command.

Zhao Chunlai sighed helplessly, handed the thermos in his hand to Luo Rui, and then walked in with his men.

Luo Rui found this strange combination of father and son quite interesting.

The father is a forensic doctor and the son is a trace investigator, and both are experts. I don't know how they get along with each other.

Zhao Chunlai has a tougher style. Besides his seniority, he is also not afraid of trouble. In the past, when Yang Qian was the captain of the criminal police brigade, he ignored him.

Except for Wei Qunshan, he will not be nice to anyone in the bureau.

Luo Rui has been working with Zhao Chunlai since the Zhu Lizhi case. Now Luo Rui is the head of the criminal team of the Haijiang Branch. He will inevitably have to deal with this old man in the future, so he tries to be as cautious as possible when dealing with this old baby.

Time passed slowly. Luo Rui and Cai Xiaojing had been waiting outside the door. It was almost afternoon when Zhao Chunlai finally came out with a tired look on his face.

He pulled his hands out of the blue latex gloves and turned the gloves inside out, so that the side that had touched the body was tucked inside to avoid contamination.

He said, "I need to take the body back for autopsy. Is there anyone else at home? I need a signature."

Luo Rui shook his head: "No close relatives, but some distant relatives. By the way, what was the cause of death?"

Zhao Chunlai sighed, "Preliminary speculation is that he was starved to death or died of thirst, just like his grandson. Let's wait for the autopsy report. There may be other reasons. I don't know what grudge the murderer had against his family. He even wiped out the entire clan."

Luo Rui had observed the body before and found no external injuries on Qiao Dahai's body.

The murderer tied him to a wheelchair and sealed his mouth with tape. In addition, his lower limbs were paralyzed, making it difficult for him to move.

This building is not an elevator apartment, but a seven-plus-one building with only two households living on each floor.

Qiao Dahai's neighbor just came back from the countryside today, and no one will notice him at all, so he has no way out.

Qiao Jun was kidnapped by the murderer more than a week ago. Luo Rui calculated in his mind that the murderer should have committed the crime around February 17th.

So far, three people have died, Peng Li, Qiao Jun, and Qiao Dahai. The murderer did not kill them directly, but took their lives in an extremely cruel way.

Why is that?
Moreover, Qiao Jun, Qiao Dahai, the grandfather and the grandson were all stripped of their clothes. Was this the murderer trying to humiliate them, or was there some other reason?
It doesn't make sense to strip a 70-year-old man with paralyzed lower limbs, tie him up, and let him starve to death.

As for the cause of Peng Li's death, she was eaten to death by her own dog, but the murderer did not strip off her clothes when she was pushed into the concrete pipe.

Does the murderer treat women differently because he has some mercy on them?

At this time, the police had already carried the body out and were preparing to transport it to the funeral home.

Zhao Ming and his apprentices were still busy in the house. Luo Rui walked to the next room, Room 702, and knocked on the door.

Previously, the neighbor knew that someone had died, so she didn't dare to show up. When she heard the knock on the door, she hesitated for a long time before opening the door and asked in a trembling voice, "Officer, what's wrong?"

Luo Rui said: "We need you to cooperate with the investigation."

The neighbor lady said: "No, I need to cooperate with the investigation. I don't know anything."

"Please cooperate!"

Luo Rui's tone left no room for doubt, so the aunt had no choice but to open the door and move aside.

"You guys come in and say, the smell next door is scary!"

Luo Rui and Cai Xiaojing walked in and found that in addition to the old lady, there was also a middle-aged man sitting in the living room.

Apparently, he is the aunt's husband.

However, after hearing the sound, he did not turn around immediately, but hesitated for several seconds before looking towards the entrance.

Luo Rui saw that his eyes were gray and his face looked confused.

The neighbor lady quickly introduced him: "Don't be nervous, old man, there are two police officers in our house."

Then she added, "My husband is blind, he can't see you, sorry, please sit wherever you want."

Luo Rui and Cai Xiaojing nodded and had a brief chat with the aunt.

The aunt's name is Yang Ying and her husband's name is Duan Zhengchang. She and her husband stayed in the countryside to celebrate the New Year and just came back today.

Luo Rui looked around the living room. Although Duan Zhengchang was blind, his family was well off. They had new TVs and refrigerators.

Although the clothes they wore were not very expensive, they were also worth a lot of money.

There was a photo frame on the counter below the TV. In the photo, a young man stood between the couple, with the background being a campus. The young man was wearing a doctoral gown, and this should be their son.

The murderer broke into Qiao Dahai's home around February 17th, and at this time, Yang Ying's family happened to return to the countryside. Could there be such a coincidence?

Qiao Dahai was not so difficult to deal with. He was a man in his seventies and it was not difficult to subdue him.

But what about Qiao Jun? He is 1.75 meters tall and weighs more than 300 kilograms. How did the murderer subdue him?

Luo Rui just checked the refrigerator and kitchen and found that there was no food in Qiao Jun's house. He guessed that the murderer must have attacked him on the road when Qiao Jun was out buying food.

There were purple bruises on Qiao Jun's knees and the back of his thighs, where he had been hit with tools such as iron rods.

To take him away, we must use transportation.

Therefore, the murderer must have a car, and he must be a young and strong man!
After he took Qiao Jun to the old site of Haihui Middle School, he returned, tied up Qiao Dahai, and starved him to death!
The first thing to do with this series of actions is to avoid being witnessed by outsiders, and the best time to commit the crime is at night, as this minimizes the risk.

Qiao Dahai’s neighbor is not at home, which is also the best opportunity.

And the most important doubt is that the murderer not only wanted to kill Qiao Jun, but also attacked his grandfather, a half-paralyzed old man in his seventies. What kind of hatred was there between him and the murderer?
After investigation, it seems that Li Mubai's psychological portrait is no longer tenable. The murderer is not an anti-social personality at all. These three murders look like revenge killings!
Yang Ying and Qiao Dahai have been neighbors for more than ten years. They see each other every day. If you want to say who knows Qiao Dahai and Qiao Jun, the grandfather and grandson, best, she is the only one.

"Qiao Jun's parents died in a car accident when Qiao Jun was five years old. His grandmother also died at the time. The driver of the car paid a sum of money and went to jail for a few years. The money is in Qiao Dahai's hands. In addition, the old man also has his own pension. Although Qiao Jun does not work properly and hangs out every day, he can still make a living."

"Qiao Jun has always been a bad student. After graduating from junior high school, Qiao Dahai found him a job as an apprentice in car repair. But he got into a fight with someone after only a few days, so the boss didn't want him anymore..."

At this time, Cai Xiaojing asked: "Did you report the case at that time?"

If a report had been made to the police, the fingerprints would have been recorded in the fingerprint database, and Qiao Jun's identity would not have been discovered only today.

Yang Ying shrugged. "The old man paid compensation to someone. This has happened several times. In order to avoid leaving a criminal record for his grandson, Qiao Dahai paid the compensation privately."

When Yang Ying talked about Qiao Jun, she didn't look happy. It seemed that she didn't like Qiao Jun as a person.

"In recent years, those who used to hang out with Qiao Jun have gotten married and had children, but he himself has no place to go, so he stays at home all day, not going anywhere, eating high-calorie food every day, and has become so fat. By the way, Qiao Dahai is dead, and I haven't seen him since.

Officer, you guys come to investigate, has something happened to this kid?"

Luo Rui didn't dare to disclose the case, so he lied: "We are also looking for him everywhere now."

Yang Ying curled her lips and said, "This kid must have done something wrong, otherwise you wouldn't have sent so many police officers. It's scary just thinking about it."

Luo Rui asked: "You just said that Qiao Jun stayed at home all day, so do you know who he contacted outside? Or does anyone come to see him often?"

Yang Ying thought for a while and shook his head: "I have never seen anyone come to see him. He is so fat, who would come to see him?! He is panting like a pig when he goes downstairs. If he continues like this, he will definitely get sick.

However, Qiao Jun does not have a very good relationship with his grandfather. This kid often asks Qiao Dahai for money. If Qiao Dahai doesn't give him money, the two will quarrel, and they quarrel several times every month.

Qiao Dahai also has a miserable life. He has difficulty moving and has to sit in a wheelchair all day. Our community is an old one and there is no elevator, so he can't even go out.

Qiao Jun was the one who went to buy groceries and other things. That guy would buy enough for a month at a time, and it didn’t matter whether they were fresh or not.

Sometimes, when I saw him going out, I told him to take his grandfather out for a walk and get some sun, but he would glare at me! So, this Qiao Dahai, dead or alive, is actually the same, he can't show up in public. The last time I saw him was several years ago, when his skin was frighteningly white..."

Yang Ying's words were like pouring beans, and they kept pouring out. Cai Xiaojing took out her cell phone and pulled up a photo of Peng Li, which she had taken in her rental apartment last night.

"Please take a closer look. Has this woman ever come to see Qiao Jun?"

"Wait a minute, I'll go get my reading glasses." After saying that, Yang Ying walked towards the bedroom.

Only Luo Rui, Cai Xiaojing and Yang Ying's husband, Duan Zhengchang, were left in the living room.

During the conversation, he had been listening silently. Although he could tell the direction of the conversation by the sound, out of politeness he kept looking at the TV so as not to let the guests see his gray eyes.

Seeing his wife leave, he smiled and nodded slightly.

Luo Rui also nodded, even though the other party couldn't see it.

After Yang Ying came back, she did not sit down. She picked up Cai Xiaojing's mobile phone and started looking at it.

She looked at it carefully and frowned.

Seeing her expression, Luo Rui knew there was a chance, but he didn't dare to rush her.

"I seem to have seen this girl before, but I can't remember."

Luo Rui hurriedly said: "Think about it carefully again."

Yang Ying returned the phone to Cai Xiaojing: "I should have seen her before, that was many years ago. This girl came to see Qiao Jun, but I haven't seen her in recent years."

Peng Li and Qiao Jun were in a relationship, so it was normal for her to come to the latter's home, but the main question is, has she come here recently?

The key point is whether these two people have had contact with other people.

Yang Ying's answer failed to provide any definite clues, and Luo Rui and Cai Xiaojing were both a little disappointed.

After the questioning, the two men walked out of the house and Zhao Ming's work was finished.

The group took the police car back to the police station. On the way, Zhao Ming said: "There are no signs of the house being pried open, and there are signs of wiping in the living room and the deceased's bedroom. We did extract a lot of fingerprints and hair, but there is not much hope.

However, I found several footprints under the distribution box near Haihui Middle School this morning. After returning, I will do a footprint inspection to see if there are any that match the characteristics of the murderer. "

……

At six o'clock in the evening, in the large conference room of the Haijiang Branch.

Experts from the provincial department and branch leaders sat at the top of the conference room, conducting criminal analysis on this serial murder case.

After two days of preliminary investigation, a lot of clues were collected, but the murderer has not yet surfaced.

To everyone’s surprise, Zhao Ming actually found suspicious footprints.

The footprints came from under the distribution box, and the murderer may have been there at the time.

After comparative analysis, Zhao Ming speculated that the murderer's height was between 175cm and 180cm, and his age was between 25 and 28 years old.

Because the deaf-mute person who delivered the USB drive had come into contact with the murderer, a portrait artist from the provincial department also drew a facial portrait.

The photo was projected on the big screen, and Luo Rui saw that the man was wearing a black baseball cap and a mask. Not only that, he was also wearing a black hoodie and covered his head with the hat.

The murderer wrapped himself up so tightly that even his eyes were not exposed.

The police station found a sign language expert, and after communicating with the deaf-mute, the deaf-mute told him that the murderer was indeed over 175cm tall, and although his age could not be seen, he had a very straight and strong body.

The murderer asked him to deliver a letter to the police station's reporting box and then gave him some money.

The murderer communicated with the deaf-mute using sign language throughout the process and did not say a word. The deaf-mute said that he had never seen him speak.

Never talked before?

This surprised the criminal police present. It is very difficult for ordinary people to communicate with deaf-mute people using gestures, let alone mastering it skillfully?
When a normal person communicates with a deaf-mute, they must gesture and speak at the same time. If they don’t speak, it is difficult to make things clear, and it is difficult for ordinary people to refrain from speaking!
Unless the murderer is deaf-mute? Or he has deaf-mute relatives or friends, there is no explanation!

Almost all detectives agreed with the reasoning of this clue.

Luo Rui had nothing to say about this.

The murderer is a young man between 25 and 28 years old, who is good at electrician and cement work and has strong operational skills. Judging from the monitoring equipment he purchased from abroad, he is not short of money. Moreover, he can also speak sign language!

In addition, Cai Xiaojing immediately reported the results of her and Luo Rui's investigation today, which completely overturned Li Mubai's psychological portrait of the murderer.

The idea of ​​anti-social personality is totally untenable!
If this is true, then the murderer would have chosen his victims randomly and would not have had any common features.

Three victims have now emerged. Not only do they know each other, but they also have a close relationship with each other.

No matter how you look at it, this is a revenge serial murder case!

After listening to the report, Wei Qunshan looked a little more relaxed. After all, the murderer would not kill people for no reason and would not attack innocent people. This was somewhat of a relief.

At this point, Li Mubai could no longer sit still. His confident speculation turned out to be groundless, which made him lose face.

In fact, if you don't investigate further, at first glance, it does seem as he inferred.

However, in any case, we should base our judgment on facts rather than making groundless guesses.

Luo Rui used to be like this, but later, he came into contact with more and more cases, and the truth he saw was not what he had inferred at the beginning, which made him dare not speak carelessly most of the time.

For example, in the case of Zhu Lizhi, she forced so many girls to sell themselves. Is she innocent?

Is Fan Hang, who killed him, guilty? Feng Qiang later also killed Fan Hang to avenge Zhu Lizhi. Is he right or wrong?

Guo Yun, this name has always been in Luo Rui's mind, and he will never forget this woman in his life!
She hid her real name and wanted to live an ordinary life. She was bullied all her life. From her mother to the people around her, no one treated her well. She was also imprisoned and played with by Huang Biao and his son. In a rage, she killed several people!

Her father told her to live like a beast, but in the end, she rode a motorcycle and took her mother to the cliff to die. But in the end, she let go of her mother and flew to the cliff alone. Is she really guilty of a heinous crime?
When Kim Bok-nam picked up the sickle, someone was destined to pay a heavy price for his actions!

After summarizing the case, a new direction of investigation will be started.

Li Mubai had already left and Wei Qunshan ignored him.

Du Feng led the team to investigate the city's sign language schools and deaf-mute population in an effort to track down the murderer.

Luo Rui and Cai Xiaojing continued to investigate the social background and interpersonal relationships of Peng Li, Qiao Jun, and Qiao Dahai, in order to find out the murderer's motive.

After receiving the order, everyone in the Haijiang Branch got busy.

Luo Rui and Cai Xiaojing returned to the office and prepared to call Chu Yang to see if they could find out any results from their investigation.

……

Ten o'clock at night.

Song Changming picked up the briefcase from the passenger seat, got out of the car, closed the door, and looked up at the low night sky.

Under the light of the street lamps, he saw tiny snowflakes floating in the night sky.

It looks like this is the last snow this year!
Song Changming muttered something, glanced at the parking space, and found that his daughter's car had not returned yet.

He looked at the expensive watch on his wrist and it was already past ten o'clock.

Without thinking much, he shrank his neck and walked into the corridor.

He took the elevator upstairs and first looked at the door of his neighbor opposite. The ribbons on the two pots of green plants had not been removed yet.

"Luo Rui?"

Song Changming muttered again, this young man is really capable. He heard from his father-in-law Mo Liguo that he bought the house in full with his own money, and the name of Mo Liguo's daughter is also written on the house title.

A policeman, no, this young man is not a policeman yet, how did he get so much money?

If he didn't have a girlfriend, Song Changming would want to introduce him to his daughter.

This kid has a bright future ahead of him!

After using the key to open the door, Song Changming's wife had already placed the freshly heated chicken soup on the dining table.

His wife knew what time he would come home every night and tried her best to do what a full-time housewife should do. Song Changming was very satisfied with this.

The only thing I am not satisfied with is that my daughter insists on becoming a star.

"Where's Huahua?"

"She went out to play with her friends and said she would be back later."

"You stupid girl, you're always out of tune and don't even go to work! What's wrong with being a civil servant? Why do you have to be a star?"

Song Changming kept cursing, but his wife didn't dare to disobey him. She just rolled her eyes at him and went back to the bedroom.

After Song Changming finished his soup, he went straight to the study without putting the bowl into the kitchen.

Every night when he gets home from get off work, the first thing he does is open the letter.

That’s right, open the letter!
The mailbox downstairs in their house is filled up every day. In addition to letters of requests and requests, there are also many other things in it.

That's how he got the famous watch on his wrist.

But today, he saw only a few small letters on the desk.

He felt disappointed at once, but fortunately, there was another letter with bulging contents that immediately attracted his attention.

He picked it up, cut open the envelope without hesitation, and unexpectedly poured out two USB flash drives from the envelope.

Song Changming blinked and his heart sank.

After so many years in the officialdom, he understood the importance of USB flash drives. How many people have been ruined in this way? What's more, he had an anonymous letter in his hand!
Song Changming immediately thought of the two actresses he had sex with during the Spring Festival TV party. Could it be that they filmed a video at that time?
Thinking of this, Song Changming quickly turned on the desktop computer and inserted one of the USB drives into the card slot of the host computer.

He didn't know much about computers and it took him a while to finally find the video.

After Song Changming clicked the mouse, the video popped up immediately. In order to see it more clearly, he enlarged the video so that it filled the entire computer screen.

As soon as the video started playing, he opened his mouth and all the blood in his body flowed back to his forehead.

The person in the video was his daughter, Song Fanghua.

She was tied to a chair, her mouth was stretched open and a piece of glass tube was stuffed into her mouth. The glass tube was one meter long and connected to a funnel-shaped glass dish. The glass dish was not sealed and had pores, and a piece of candle was burning at the bend of the glass tube!
Song Fanghua placed a stainless steel rack in front of him to support the glass dishes and prevent them from falling to the ground.

But this is not the most dangerous thing!
A tiny cobra was curled up in the dangerous glass dish, with its flat head facing the burning candle. As long as the flame went out or the candle burned out, the cobra, as thick as a thumb, would slide towards the glass tube and drill into Song Fanghua's throat.

Song Fanghua looked at the cobra in the glass with fear in her eyes, and her whole body was shaking!
Outside the video, Song Changming's face was pale, his head was congested, and his heart was beating wildly. He stood up and fell to the ground with one plop!
He struggled to get up from the ground, took out his cell phone from his coat, and prepared to call the police, but the video continued to play.

A piece of white cardboard appeared in the camera:

[If you dare to call the police, I will cut your daughter into pieces and throw her into the Linjiang River so that you will never find her body! ]
