Detective: From the Police Academy

Chapter 383: Blood in the handle ring!
"Director Luo, there is a major discovery!" Yi Chunlin turned around, his tone full of excitement.

Immediately, everyone in the room ran over together.

Qiao Xue was the most active. After all, she had participated in the preliminary investigation of this case. The Yonghe Municipal Bureau did not even think of it as a homicide case at the time. Yi Chunlin was a senior forensic doctor, and his discovery made her heart tremble.

"Doctor Yi, what did you find?"

Yi Chunlin shone the inspection light in his hand on the knife handle on the ground: "Look, what is this?"

Luo Rui bent down and saw a kitchen knife dropped on the ground. The handle was made of wood, and there was a stainless steel ring connecting the handle and the blade.

Because the kitchen knife fell to the ground, the steel ring had fallen off, revealing the small, ugly handle inside.

Under the blue light, the bloodstains originally hidden in the copper ring appeared.

Qiao Xue was shocked: "Human blood?"

A normal kitchen knife is used to cut meat and will not cause bleeding, unless it is used to kill chickens or fish.

Yi Chunlin did not answer directly, but stood up and pointed to the cupboard above: "The knife was in the cupboard. As soon as I opened the door, it fell out. It was placed vertically in the gap before."

Everyone looked up and saw that the cupboard was filled with many bottles and jars. At first glance, they had no idea what was inside.

Luo Rui looked towards the corner of the kitchen counter and found two commonly used kitchen knives on the knife rack, but they were a little older after falling to the ground.

"Call Ms. Jiang!"

Qiao Xue immediately brought Jiang Mei, who was hiding behind the crowd, over.

Luo Rui stared at her: "Is this knife yours?"

Jiang Mei frowned, just took a look, and said, "Yes."

"Look carefully before you answer."

"It's ours. There are three kitchen knives in the kitchen. I bought this one a few years ago."

"Did you put this knife in the cupboard?"

Jiang Mei shook her head: "No, I put them all on the knife rack."

"Then why didn't you notice that there was a knife missing from the knife rack?"

"I... it's like this, officer. Since Jingjing disappeared, I haven't cooked often. At most, I cook a bowl of noodles. I rarely use the kitchen knife, so I didn't pay much attention..."

Luo Rui stared at her and saw that she didn't seem to be lying. However, this matter was too important. What if, as He Junzhu said, Jiang Mei and Zhang Jing's "disappearance" were closely related? After more than half a month, she would have prepared herself mentally and practiced her lying expressions. It would be difficult to make a breakthrough in this case.

Luo Rui has some knowledge about psychology and micro-expressions, but for him to be able to observe things in detail and understand people's hearts, that would be too magical, and he is not a systematic person.

Luo Rui reached out and touched the kitchen counter, twisting it with his fingers.

Then he looked at the rag hanging on the wall, which was dry.

Finally, Luo Rui looked at Qiao Xue and said, "Go to the gas company and check the gas usage of this household to see if it is true as Ms. Jiang said.

Also, call the water plant right after checking. I want the water consumption of Ms. Jiang's home on December 12rd!"

Qiao Xue nodded immediately. As soon as she went out, she ran into Feng Jianqiu who arrived later.

Feng Jianqiu was puzzled when he saw the provincial department's commissioners gathered at the kitchen door, but he couldn't ask directly, so he quickly pulled Qiao Xue aside and asked, "Xiaoxue, did you find out something?"

Qiao Xue is his old subordinate, and Feng Jianqiu usually takes good care of her. After all, Qiao Xue is considered the best female criminal police officer in the Yonghe City Criminal Police Detachment. When her master was sacrificed, she subdued the armed gangster alone. Just this made a bunch of old and young men in the Municipal Bureau exclaim: Women are as good as men.

Qiao Xue sighed and replied in a low voice: "Team Feng, we found a knife with blood on the handle, but we are not sure whether it is human blood..."

As she spoke, Qiao Xue looked around the room and saw that no one noticed her. She then said, "It is very likely that Zhang Jing's disappearance and kidnapping are not as simple as that."

Feng Jianqiu widened his eyes and swallowed his saliva: "This..."

Qiao Xue no longer cared about him and wanted to go to work immediately, but Feng Jianqiu immediately pulled her back: "Xiaoxue, have you told Luo Chu about the relationship between your master and him?"

Qiao Xue shook her head: "I didn't plan to tell you."

"One more person means one more way. This Director Luo will be able to help you in the future. We police officers, in addition to solving cases, also care about inheritance..."

"Captain Feng, I'm going to have to get busy first." Qiao Xue didn't want to talk about this and trotted away quickly.

Feng Jianqiu walked cautiously to the kitchen door and saw Yi Chunlin squatting on the floor, putting a kitchen knife into the evidence bag.

Because of the discovery of bloodstains, Yi Chunlin was energized. He brought his assistant and continued to search the kitchen carefully with a survey light.

Zhao Ming stayed in Zhang Jing's bedroom, investigating subtle clues, and never came out.

Cai Xiaojing continued to in-depth her questioning of Jiang Mei and no longer focused the investigation on the disappearance case.

"Ms. Jiang, please answer the previous question."

Jiang Mei was not stupid either. The handle of the knife was stained with blood, and it was a kitchen knife that had not been used for a long time. Naturally, she was listed as the key suspect in the minds of these policemen.

She was in a trance: "What's the problem?"

"Did you know that Zhang Jing had an unusual relationship with your boyfriend, Peng Tao?"

"I……"

"Think it over before you answer!" Cai Xiaojing warned.

Jiang Mei compromised: "I know."

"Why did you lie before?"

"I don't want to lie." She raised her head, her tone sounding aggrieved and humiliated: "Officer, how can I say such a thing? My aunt's boyfriend is having an affair with my niece. If others knew about this, how would I live?"

Cai Xiaojing did not sympathize with her and asked coldly: "How did you and Peng Tao know each other?"

"Zhang Jing and I met by chance when we were visiting a 4S store."

Was it intentional or unintentional... Luo Rui, who was eavesdropping on the conversation, immediately realized the problem. Could it be that Zhang Jing intended to get his aunt in touch with this Peng Tao?

What exactly is going on? We have to get the truth out of Peng Tao.

Moreover, Jiang Mei was previously called "Jingjing", but now that the relationship between the three people has been exposed, she changed her words and called her niece by her name. It seems that she still resents Zhang Jing in her heart.

"How long have you been dating?"

"Almost a year."

"Do you have any plans to get married?"

Jiang Mei sighed: "Of course I want to get married, but I don't know what Peng Tao thinks. He seems... doesn't seem to want to get married."

"Have you ever borrowed money from Zhang Jing?"

"I borrowed it a few times."

"Did Peng Tao ask you to buy a car for business needs, and you borrowed money from Zhang Jing to help him complete the business?"

Hearing this, Jiang Mei was excited: "Officer, do you suspect that Zhang Jing's disappearance has something to do with me? I tell you, Zhang Jing is my niece, I would never harm her, don't wrongly accuse me!"

Cai Xiaojing stared at her, carefully observing her expression, and then said: "You just need to answer the questions, and we will make our own judgments on other matters."

"I...I asked her to borrow money."

"Did she borrow it?"

"No, she didn't lend it to me. She found a boyfriend, who was a college student and had no ability to make money. Zhang Jing often helped him, and she wanted to buy a house and move out to live with her boyfriend.

Zhang Jing and my brother had a big fight because of this reason.

Officer, if anything happens to Zhang Jing, you should go find this man, there must be something wrong with him!"

"You don't have to tell me that." Cai Xiaojing replied, then looked at Luo Rui, indicating that she had finished asking questions.

Luo Rui narrowed his eyes and added one last question: "Ms. Jiang, what is your relationship with Zhang Yongcheng?"

Jiang Mei was stunned for a moment, not understanding what this meant.

"Your brother's last name is Zhang, but you and he have different last names. That's what I'm curious about."

"I have my mother's last name." Jiang Mei answered with a normal expression. It seemed that she must have been asked this question frequently.

This answer is not a lie, but there must be a deeper reason. Zhang Yongcheng is the chairman of the tobacco company. His daughter and sister both work in the Tobacco Bureau. There are probably more than these two people. After all, Qi Tongwei can get a job for the dogs in his village, let alone the tobacco people?
At this time, Cai Xiaojing said, "Ms. Jiang, please provide us with Peng Tao's company and address."

Jiang Mei gave the address and did not resist.

After Cai Xiaojing took note of it, she continued, "Ms. Jiang, please don't leave the city or go anywhere in the near future. When we contact you, please cooperate with the investigation. Can you do it?" "I know, I will cooperate with you." Jiang Mei held her forehead with her hand, looking very distressed.

"There is one more thing." Cai Xiaojing looked at the technical police officer who was investigating the house and said, "You should not live in this house for the time being. You can live in your relatives' house. If it is inconvenient..."

Feng Jianqiu on the side immediately said: "If you are in trouble, our municipal bureau will provide you with accommodation, or you can go to a hotel by yourself and we will reimburse the expenses."

We definitely can't trouble the provincial department's commissioner with this matter. Feng Jianqiu still has a good eye.

He had figured out everything now, so this pretty picture was probably gone.

As for Jiang Mei's suspicion, it cannot be cleared all at once unless there is evidence to exclude her. Feng Jianqiu quickly gave a look to his two subordinates.

It goes without saying that they need to monitor Jiang Mei at all times. Since their subordinates are both men, this is naturally not easy to do. One of them immediately makes a phone call and asks the detachment to send a female police officer over.

Seeing so many people in the house and the house being requisitioned by the police, Jiang Mei had no choice but to go back to the bedroom to pack her luggage and prepare to leave immediately.

Because she was wearing pajamas, she wanted to close the door and change clothes, but Feng Jianqiu didn't allow her.

Lin Chen understood what he meant. He was afraid that something might happen. If Jiang Mei became a suspect and committed suicide out of fear of punishment, everyone would be in trouble.

And it was not easy for him to assign someone from the provincial department, so Lin Chen followed Jiang Mei into the house so that he could monitor her at any time.

At this moment, everyone was busy in the room, some collecting evidence, some conducting investigations.

Feng Jianqiu came to Luo Rui and asked cautiously, "Director Luo, do you want to summon Jiang Mei's boyfriend Peng Tao?"

"Don't worry, let's wait until we finish investigating the scene. But you can send someone to keep an eye on Peng Tao and don't let him run away."

"Okay, I'll do it right away." Feng Jianqiu replied hurriedly.

-------------

Ten o'clock in the evening.

Yonghe Municipal Bureau, conference room.

As soon as Luo Rui entered the room, Li Xu, the detachment leader, immediately stood up and came forward to greet him enthusiastically: "Director Luo, I apologize for your apologies. You have been so busy since your first day here that you haven't even had dinner yet. We are sorry for not hosting you well enough."

Luo Rui didn't look at him, but glanced into the conference room and found that neither the deputy director nor the director of Yonghe City were there.

Li Xu was also a smart man, so he naturally knew what Luo Rui was looking at. He immediately said, "Didn't you kick Zhang Yongcheng out of the car during the day? The incident between him and Xing Guolong pissed off several bureau chiefs. In the afternoon, the bureau chief took them to the municipal party committee to resolve the dispute."

Li Xu naturally knew what happened throughout the day, it would be strange if Feng Jianqiu didn't report it to his superiors.

Luo Rui glanced at him, and the old guy smiled innocently, confirming without a doubt that it was him.

In fact, Luo Rui didn't care about this matter. What he cared about was Qiao Xue. She was from the Yonghe Municipal Bureau and was now transferred to the Provincial Department. She was his subordinate. If she was disloyal, then she must be transferred.

Similarly, Zhuo Yong and Sun Zhihao were like leaky walls, and they didn't know how many pairs of eyes were watching them in secret.

However, Luo Rui didn't care about them. After inspecting Hejiang City and Qingyang City, if these two people were not obedient, he planned to transfer them directly to avoid being a nuisance.

Luo Rui said, "Captain Feng, there is new progress in Zhang Jing's case. Let's have a meeting first."

"Yes, yes." Feng Jianqiu invited him to the seat of honor.

The people from the provincial department and the criminal police from the municipal bureau sat on both sides and looked at Luo Rui.

Luo Rui looked at the people on his side and said, "Tell me what you found out."

Fang Yonghui stood up first, holding a notebook in his hand, and replied: "Zhang Yong and I have asked the security personnel of Baita Community. This community is an old community with not many residents and the security is not strict.

The security team consists of a couple, an old man and an old woman, both of them are elderly.

The old man is usually on duty 24 hours a day. If something happens, he will ask his wife to help him for a while, so there are often no security guards on duty in this community. In other words, if Zhang Jing goes out or a stranger enters the community, the security guard will not know.

In addition, the surveillance camera at the entrance of the community is just a decoration and has been broken for a long time, so we have no way to start the investigation from the surveillance camera.

However, we learned from the security guard that he was sure that Jiang Mei left home at 7:30 on the morning of the 3rd and returned at around 8:00 the next morning. He didn't know whether Jiang Mei went home or Zhang Jing went out during that time."

At this point, Feng Jianqiu nodded and said, "This is similar to what our city bureau found, there is no difference."

Luo Rui ignored him. This guy just wanted to find some sense of existence.

After seeing Fang Yonghui sitting down, Chu Yang stood up and said, “Jiang Mei lives on the first floor. There is only one neighbor on the first floor, but the house of this family has been vacant for a long time. Sun Zhihao and I went to the second and third floors.

On December 3rd, there were only elderly people at home. One of them, who was paralyzed in bed, confessed that at 8 o'clock in the evening on the 3rd, he heard a woman shouting downstairs, but he couldn't hear it clearly and didn't hear what she was shouting, so he didn't pay attention to it.

In the evening, after all the residents had gotten off work, we learned another thing: Jiang Mei's boyfriend Peng Tao came to see Zhang Jing at noon on the 2nd, when Jiang Mei was at work.

After we asked the security guard, we confirmed this statement. Peng Tao did come at noon on the 2nd, but he only stayed for half an hour before leaving.

Zhang Jing also left the community at 1:30 p.m. that day and returned at 11 p.m.

"It seems that Peng Tao is indeed a suspect." Li Xu said. He took out a cigarette and put it in his mouth. Just as he took out the lighter, Luo Rui glanced at him and he quickly put the lighter away.

Lin Chen continued, "In the afternoon, I went to the Telecommunications Bureau to check Zhang Jing's call records. Her most recent call was at 5pm on the 3rd. The call was to He Junzhu and lasted for an hour..."

Before she finished speaking, Feng Jianqiu immediately interrupted and said, "After Officer Lin found out about this, our comrades from the Municipal Bureau immediately questioned He Junzhu. It is true. The content of the call is here with me, Director Luo, please take a look."

Luo Rui took the inquiry record he handed over, which was nothing more than some flirting, or "did you eat?" "What did you eat?" Normal conversations between ordinary lovers.

Lin Chen was very dissatisfied with Feng Jianqiu interrupting her. She curled her lips and glared at him fiercely.

These findings did not play any important role in the case. The highlight was on Yi Chunlin and Zhao Ming, so Luo Rui looked at them eagerly.

Yi Chunlin left Zhao Chunming aside and took charge of the forensic work of a criminal case for the first time. He was also transferred to the provincial department. Naturally, he hoped to achieve some results so as to avoid being criticized by Zhao Chunlai, so he worked very hard and barely ate a bite of food that day.

He cleared his throat, picked up the photo of the kitchen knife, and faced everyone: "Director Zhao and I have found several things. First, there is blood inside the handle of this hatchet. Everyone knows this. I can preliminarily determine that this is human blood! But it is not the blood that flowed from Zhang Jing. The laboratory of the Municipal Bureau is still verifying it.

Second, the knife had been cleaned very thoroughly, except for the blood stains in the copper ring of the handle, so the evidence was retained.

Secondly, we found traces of chemical cleaning solutions on Jiang Mei’s kitchen floor, near the floor drain, and on a laminated panel of the cabinet below.

We extracted the chemical residue from the traces and found that it was 84 disinfectant! This stuff must be used to remove blood stains.

Judging from the area of ​​the cleaned marks, the amount of bleeding was not large and was not fatal.

Apart from the bloodstains we found in the kitchen, no traces were found in the bathroom, toilet, bedroom, etc. We speculate that Zhang Jing was attacked in the kitchen. "

After hearing this, Li Xu's brows frowned even deeper. This was a clue that the Municipal Bureau had not found. He glanced at Feng Jianqiu, and the two of them stared at each other, both feeling helpless.

Li Xu explained: "We are responsible for this matter. On December 4, after we received the call, we also conducted a detailed investigation of Jiang Mei's home, but did not find any bloodstains."

If you had discovered it, you wouldn't have dragged the case on for so long... Luo Rui looked at Lin Chen and said, "Remember, we didn't find 84 disinfectant in Jiang Mei's home during the day, and she also said that there was no such thing at home. This is a crucial clue.

The DNA report will come out tomorrow morning, proving that the blood on the knife handle came from Zhang Jing, so Zhang Jing was attacked in the kitchen.

The suspect used a kitchen knife from Jiang Mei's home to commit the crime and did not bring his own weapon, which shows that he did not intend to commit the crime in the first place.

Forensic doctor Yi said that the amount of bleeding was not lethal, which means that Zhang Jing might have been alive at the time, or had already fallen into a coma. In order to remove the bloodstains, the suspect used 84 disinfectant, but we did not find the container in Jiang Mei's home, so the suspect must have ventured out and bought the disinfectant.

The suspect avoided the security guards, and he would not leave for too long or go too far. Tomorrow morning, send people to visit supermarkets and convenience stores around the community to find out who bought 84 disinfectant on the rd and find this person! "

Feng Jianqiu immediately said, "Director Luo, leave this matter to us."

Luo Rui nodded, and then said: "There is one more thing. Whether Zhang Jing is dead or unconscious, the murderer must have taken her away. It is very difficult to leave the community with someone..."

Zhao Ming stood up and said, "I checked Zhang Jing's bedroom. There is a very clear square mark next to the bedside table. This mark is very white, and the rest is dust. It is about the size of a 26-inch suitcase."

This was another situation that the city bureau had not found. Li Xu slapped his forehead and asked, "Can a 26-inch suitcase fit one person?"

Zhao Ming replied, "It depends on how you put it in. We compared Zhang Jing's height and weight, and asked a female comrade to try it out. If you force your arms and calves, you can force it in."

Hearing this, Li Xu had no choice but to nod his head, and then said, "Then what is the motive? We checked Zhang Jing's bank card and passbook, and found that no one had touched the money in her card."

Luo Rui looked at him and said, "It's too early to talk about motives now. Everyone has heard what Director Zhao said just now. If the suspect used a suitcase to take the person away, and Captain Li said that the money in Zhang Jing's bank card was not missing.

So we might as well be bold now. I'll be frank. I think the possibility of Zhang Jing being alive is very small. Now we are no longer looking for a living person, but her body!"

Once this was said, it was equivalent to classifying the case as a homicide.

Li Xu and Feng Jianqiu looked at each other and exchanged glances.

Luo Rui tapped the table lightly with his knuckles, waiting for the two men to express their opinions.

The provincial department is here to assist in solving the case. After all, the case belongs to the municipal bureau. If Li Xu disagrees, then the case cannot be investigated as a homicide case.

Murder cases must be solved, which sounds exciting, but it will cost a lot of money and police force.

Li Xu pondered for a moment and said, "Director Luo, how about this? Once the DNA results come out tomorrow morning and it is confirmed that the blood on the handle is Zhang Jing's, we can draw a conclusion?"
