Detective: From the Police Academy

Chapter 485: Murder method!
It was already two o'clock in the morning when Jin Jiahui and Guo Lexuan rushed back to the Municipal Bureau.

When they learned that Zhang Yao was the mastermind behind this serial murder case, both of them were shocked.

It took Jin Jiahui a long time to recover from her emotions. She sat in the conference room, stunned. She didn't hear a single word of the case meeting chaired by Li Pinghai.

Luo Rui and a few others had already gone back to rest, which meant that the only participants in the meeting were police officers from the Municipal Bureau. Even Guo Lexuan was blocked outside the meeting room and was not qualified to attend the meeting at all.

As for why they were in a hurry to hold a meeting overnight, it was mainly to sort out the specific details of the case. Luo Rui's case was solved too quickly, in just three days, which made Ding Wangjun and Li Pinghai unable to cope with it and had no time to respond.

As a forensic doctor, Jin Jiahui had no right to speak at all. She just sat in a chair in the corner and listened quietly.

Li Pinghai had followed Luo Rui for two days and was most familiar with the context of the case, so he presided over the meeting.

At this time, he stood in front of the electronic screen, glanced at everyone, pointed at the photos of Liang Yi and the murdered woman on the screen, and said: "The breakthrough in this case is these two people, from Qin Province, they are college graduates, the man is Liang Yi, and the woman is Hu Lijun."

"These two people arrived in Longchuan City on December 23rd to look for work. They first stayed in a hotel for two days and then rented a room in the Lotus Community on December 25th."

Li Pinghai pointed at the scratched mattress on the screen and said with a serious expression: "On the same day, Liang Yi and Hu Lijun discovered a huge amount of cash hidden in this mattress. As for how much money it is in total, we don't know yet, but it is estimated to be more than five million.

After discovering the money, the two young men wanted to keep it for themselves and moved out the next day.

We have already figured out where this money came from. It was left by the previous tenant, Yong Cong.

Yong Cong disappeared on November 3 last year, and his body was found in the Longchuan River on the 5th. The Longchuan Police Station speculated that he had drowned.

At this point, not only Li Pinghai, but also several directors and deputy directors such as Ding Wangjun had gloomy expressions and sighed one after another.

Jin Jiahui gritted her teeth and clenched the ballpoint pen in her hand, almost breaking it. She didn't sympathize with Yong Cong, but felt sorry for the two newly graduated college students.

Speaking of greed, who isn’t greedy?
When faced with huge temptations, very few people can remain calm and rational.

It's like picking up someone's lost wallet on the ground and seeing a thick stack of banknotes inside the wallet. How many people would return it to the original owner?
What’s more, it’s five million?
Human nature is the least worth testing. There is a very classic case in which a girl brought home a boyfriend from a rural family.

The girl's parents didn't want their daughter to marry this boy with such poor conditions, so they came up with an idea.

In front of their daughter, the parents gave the boy a red envelope of one thousand yuan. When the boy said goodbye, the parents gave the red envelope to the boy and secretly told their daughter, "When the time comes, ask him how much money is in the red envelope."

If the boy is honest, he will tell you the truth. If he does not answer truthfully, it proves that this boy is not worthy of entrusting your life to.

After that, the girl asked her boyfriend how much money his parents gave him in a red envelope, and the boy replied: five hundred.

The girl refused to give in and said that the boy had lied to her. The boy swore and said that he was telling the truth.

In the end, the girl listened to her parents' advice and felt that the boy was dishonest and really not worth it. Later, the conflict between the two became more and more serious, and finally led to a breakup.

This was in line with the parents' wishes, as their daughter finally married into a family of equal status.

But little did people know that the red envelope, which was originally worth one thousand, actually only contained five hundred!
The mother stuffed one thousand yuan into the bill in front of the girl, but when she handed it to the boy, she secretly took out five hundred yuan.

The boy didn't lie at all. There was indeed only 500 yuan in the red envelope.

So, never test human nature!
At the same time, Jin Jiahui also felt very upset. If she had stood up and bravely raised questions during the autopsy of the second victim, Yong Cong, on November 6 last year, the following events would not have happened, and at least many people would not have died!

Li Pinghai recounted the case in a torrent of words: "Then, the body of Hu Lijun was found. It was forensic doctor Jin Jiahui who questioned the drowning. Here, we should affirm the work of forensic doctor Jin. I encourage her."

Everyone looked at Jin Jiahui and nodded to her, but there was no expression on her face.

"Through suspicions about Hu Lijun's body, Luo's subordinate Chu Yang, Officer Chu, and Huang Ting from our Municipal Bureau were investigating the rental house of the second deceased, Yong Cong, and found this Liang Yi.

During this period, Hu Lijun's body was destroyed. The next step was to hunt down two criminals nicknamed Lao Er and Lao Yao. The second brother was killed by his accomplices, and the youngest brother has been rescued, but because he is critically ill, his confession cannot be obtained yet.

Hu Lijun's body was destroyed. We compared the footprints and the microbial samples we extracted and confirmed that it was these two people and a man named Yang Guoguang who did it. "

"On that night, Yang Guoguang was killed by Jiang Xiaobin and his accomplices. These three people were drug dealers, and the one who gave them the order was the mastermind behind the scenes nicknamed "Guanyin". Although we don't have any concrete evidence pointing to this Guanyin, it is very likely that she is..."

A photo of Zhang Yao appeared on the electronic screen.

The participants already knew her identity, but many of them were not very familiar with her. However, Jin Jiahui had dealt with her several times.

She pursed her lips and felt that reality was more magical and incredible than the movie.

Li Pinghai was silent for a moment: "Zhang Yao not only deliberately murdered others, but also masterminded several murders to silence witnesses. He is also the leader of a group of drug dealers in Longchuan City!"

Li Pinghai paused and wanted to drink a sip of water, but at this time, Ding Wangjun asked: "Can you find evidence of her crime?"

Li Pinghai was about to answer when Tan Peng, the head of the anti-drug detachment, spoke first: "Director Ding, after General Luo got Wu Biao's confession, we are investigating a drug dealer nicknamed 'Three Knives' based on this clue."

"Is there any result?"

"Yes, this man with three knives is actually named Hao Fan, he is 38 years old, and he is from our side, but he has Burmese ancestry and has lived in Burmese for many years.

Our anti-drug detachment's informant found a man named Arong, who is the boss of a tea business in Saitama County, Longchuan City.

Hao Fan comes to Longchuan City once a year. He is received by A Rong every time. My informant thinks that Hao Fan must come here to meet with our local drug traffickers. Jiang Xiaobin and Guanyin are both in this line of work.

I think, as long as we catch Hao Fan, we can get evidence that Guanyin, or Zhang Yao, is trafficking drugs!"

"Your idea is good!" Ding Wangjun pointed at him and said affirmatively: "We must not only find evidence of Zhang Yao's crime, but also crack down on rampant drug traffickers. This is also a big deal, and our municipal bureau cannot act alone.

In this way, the provincial department will send people early in the morning. You can communicate with Mr. Luo and others to see if you can lure this Hao Fan out!"

Tan Peng nodded: "Mr. Luo has been up for several nights. I will go find him when he wakes up."

"Without Mr. Luo, this case might have been..." Ding Wangjun sighed, and then said, "Let him sleep a little longer, don't disturb him too early."

"I see."

Ding Wangjun looked at Li Pinghai: "What about you? Can your criminal investigation team find evidence of Zhang Yao's crime?"

When asked this question, Li Pinghai felt a headache. He pursed his lips and said, "Director Ding, now we only have Wu Biao's confession..."

Ding Wangjun immediately interrupted him and said in a serious tone: "For such a big case, the confession of a suspect is definitely not acceptable. The case cannot be transferred to the procuratorate at all!"

"Yes." Li Pinghai continued, "There is also the criminal suspect nicknamed Laoyao. This person is Guanyin's henchman. As long as he can wake up..."

"You're quite thoughtful!" Ding Wangjun said directly, "Put your hopes on the confession of the suspect. This youngest guy even dares to kill his own people. How can you get him to confess? If he never wakes up, we will never close the case."

"This..." Li Pinghai didn't dare to say anything else.

Ding Wangjun looked at Jin Jiahui who was sitting in the corner, and his attitude softened a little: "Xiao Jin, I heard that you are investigating the location where the three victims fell into the water. Have you found any clues?"

Jin Jiahui came back to her senses and replied, "Director Ding, I have been collecting hydrological data in Shangpo Town these past two days. My initial judgment is that it should be at the second section of Longchuan River. The specific results still need to be verified by the Physical Evidence Center."

"Hurry up and find out the cause of death of these three victims. Without complete evidence, Zhang Yao will not confess, and the procuratorate will not accept the case."

"I'll go now!" Jin Jiahui stood up and tidied up the documents on the desk.

Ding Wangjun waved his hand: "No need to rush. It's already early in the morning and the evidence center is not open yet. Where are you going to test it?"

"I would like to trouble the comrades from the Municipal Bureau to help take the samples I have extracted to the Physical Evidence Center. I would like to visit the homes of several suspects and perhaps find out how Guanyin killed people.

My thought is that these three deaths were all fake drownings, but what about before that? Aren’t there fake drownings in other jurisdictions?”

Ding Wangjun was choked by these words and didn't dare to say anything. But Jin Jiahui was right. Guanyin used such a covert way of killing to hide the truth. Could it be that she only killed three people?

He had no choice but to nod and look at Li Pinghai who was standing beside him.

Li Pinghai did not dare to neglect it. How could he dare to confront Jin Jiahui like he did a few days ago? He pointed at Huang Ting and said, "Xiaoting, drive and take Forensic Doctor Jin there."

"Okay, Captain Li." Huang Ting responded.

Jin Jiahui left the meeting room, and Guo Lexuan, who was waiting outside, immediately came forward and said, "Do you understand everything? Tell me quickly, how did Luo Yanwang solve the case?"

Jin Jiahui walked downstairs quickly without stopping, and replied, "I don't have time to chat with you now."

Guo Lexuan frowned and said, "No, it's already so late, why don't we go home and sleep? Where are you going?"

Huang Ting, who was left behind, smiled and said, "Let's go see the stars. Do you want to go?"

"What nonsense!" Guo Lexuan curled her lips: "Senior sister, slow down, wait for me."

The three drove to Zhang Yao's home.

Zhang Guangxia’s house was allocated by his work unit. It is an old and dilapidated apartment on the third floor of a seven-story building.

The walls of the corridor were covered with graffiti drawn by children, the corridor was narrow, and the ceiling light was broken.

Because it was early in the morning, Jin Jiahui and her friends walked very lightly so as not to disturb the residents' rest.

Huang Ting took the key and warned before opening the door: "Let's be careful. This house has not been inspected yet. Try not to move things in the house. Even the garbage on the ground should not be picked up. Leave it as it is."

Guo Lexuan curled her lips and said, "Don't worry, Old Huang. I'm just doing on-site surveys. Do you know more than me?"

Huang Ting frowned: "Either call me by my name, or call me Xiao Ting, don't call me Xiao Huang or Lao Huang."

Guo Lexuan put on the foot covers and said with a smile, "Okay, Lao Huang."

Huang Ting rolled her eyes, took out the key and opened the door.

Guo Lexuan went in first. She turned on the light on the left wall of the entrance and sniffed the air: "No one has lived in this house for at least three days!"

Huang Ting was surprised and said, "You can even find this? You are really suitable for field surveys!"

"Really?" Guo Lexuan said proudly: "If you ask me, Mr. Luo's team should have someone like me, but it's a pity that he doesn't know what's good for him..."

Huang Ting was waiting for her to show off, and when she started talking, she started to retort: ​​"That's right, after all, you have a keen sense of smell, which makes you very suitable for the work of a police dog."

"You..." Guo Lexuan wanted to know how to fight back.

Jin Jiahui quickly interrupted the conversation between the two people: "Stop joking, both of you. Go inside and take a look."

The three of them walked into the living room, and the first thing they saw was the photos on the right TV wall, a wedding photo of Zhang Guangxia and his wife, a photo of the family of three, and Zhang Yao's personal photos, from her childhood to her adulthood, almost covering half of the wall. Other than that, the furnishings in the house were very simple, the TV was a small-sized LCD TV, the refrigerator was old, and the bed sheets and quilts in the bedroom were very plain, especially Zhang Yao's bedroom, the quilts were all floral quilts, and her identity was completely invisible.

Guo Lexuan first observed the bedroom, and then went straight to the kitchen and bathroom.

Because Zhang Yao is the leader of this drug trafficking gang, Guo Lexuan suspects that there must be evidence of drug trafficking hidden in her home.

Jin Jiahui went to the dressing table in the bedroom and opened the bottom drawer.

The wooden drawer was filled with medical prescriptions and a thick stack of X-rays.

The name on the medical form was her mother, Zhang Guangxia's wife.

The medical records showed that her mother was critically ill and urgently needed a kidney replacement.

The hospital bill was clamped with a clip. After Jin Jiahui flipped through it, she silently calculated in her mind that the medical expenses for Zhang Yao's mother's treatment over the years were not enough to be covered by Zhang Guangxia's salary alone. Jin Jiahui also had a rough idea of ​​the income of Zhang Yao's dental clinic.

In other words, Zhang Yao and her daughter had to bear a heavy burden to pay for their mother's medical treatment, but this was only on the surface. Jin Jiahui guessed that the reason she was trafficking in drugs was probably to make money for her mother's medical treatment.

After all, a kidney transplant costs a lot of money!
Jin Jiahui put the list in her hand back into the drawer, trying to put it back in place so that the on-site surveyors could inspect it.

Huang Ting watched Jin Jiahui and Guo Lexuan's actions back and forth, playing a supervisory role.

At this time, Guo Lexuan walked to the bedroom door and looked at Huang Ting: "Where is Zhang Yao's other residence?"

"What?" Huang Ting frowned.

"Zhang Yao must have another hiding place, but it's definitely not here."

"That's the dental clinic. She sometimes takes a rest in the clinic."

Jin Jiahui shook her head: "Not there! I've been to the clinic, there's no kitchen in the clinic, Zhang Yao often brings meals to his father, and the kitchen in this room hasn't been used for a long time!"

Huang Ting spread her hands and said, "If you ask me, who should I ask?"

Guo Lexuan said, "Old Huang, you and the people from the provincial department have been investigating the case for several days. Officer Chu was able to find the entry point of the case based on clues. Can't you use your imagination?"

Huang Ting curled her lips: "For example?"

Guo Lexuan rolled her eyes and said, "When you arrested Zhang Yao, didn't you find any other keys on her? Otherwise, how did you open this room?"

"I didn't arrest him!" She muttered, taking out her cell phone and saying, "I called the evidence management office. When I arrested Zhang Yao, the dental clinic did a preliminary inspection."

"Hurry up." Guo Lexuan urged.

After a moment, Huang Ting put down her phone and said without temper, "I asked, and the on-site survey personnel did find a key in Zhang Yao's handbag. The key is very new and is not the key to an ordinary person's door."

Jin Jiahui quickly asked: "Can you find out where this key comes from?"

Huang Ting replied: "They told us to wait, how about we go back first?"

Guo Lexuan: "Wait? Wait until when? If Mr. Luo interrogates Zhang Yao tomorrow morning and asks us to get evidence, and we've been investigating for two whole days and haven't found any clues, what should we do if he accuses us?"

Jin Jiahui also had a worried look on her face. She stroked her butt with both hands and paced back and forth in the living room anxiously.

Just as they were hesitating, Huang Ting's cell phone rang.

After she answered the phone, her eyes sparkled as she said, "There's a result. The key has been matched!"

Jin Jiahui's pupils shrank, and she and Guo Lexuan asked at the same time: "Where is the key?"

Huang Ting replied: "Longyin Mansion!"

Guo Lexuan rolled her eyes: "Where is this?"

Jin Jiahui walked straight to the door: "Let's go get the key and go to this place now."

Huang Ting said: "Longyin Mansion is a luxurious villa area in Longchuan City. It is where the rich live. The value of a villa is so high that we as police officers cannot afford it in our lifetime."

"There's no running away, so it must be this place." Guo Lexuan said while rubbing shoulders with the crowd.

At four o'clock in the morning, at the property management office of Longyin Mansion.

The property had already gone off work, but because the municipal police department called, the property manager had to get out of bed and deal with the police who arrived.

It wasn't just Jin Jiahui and her three companions who came. When Li Pinghai heard that they had found Zhang Yao's other residence, he also dragged his tired body and brought a group of people over.

If they want to prove Zhang Yao's crime, they must find solid evidence. At the moment, Li Pinghai is in the dark. Although Luo Rui is leading the investigation of the case, as the captain of the detachment, he cannot be ignorant of everything.

Ding Wangjun's attitude towards him at the early morning meeting was very telling.

The property manager rolled his glasses and raised his head from the computer: "I didn't find the name Zhang Yao. She shouldn't be the owner of our place."

Jin Jiahui thought for a moment and asked, "What's Li Fen's name?"

The property manager searched for a moment and shook his head, "No."

Li Pinghai asked: "Check this person Jiang Xiaobin?"

Guo Lexuan: "If it really doesn't work, we can just take the key and try again?"

As soon as she finished speaking, the property manager said, "There is no owner named Jiang Xiaobin either. At this time, the owners are all resting. I think if we want to try, we have to wait until dawn."

Huang Ting thought for a moment and said, "Song Guoguang, check this person out!"

The property manager sighed and said, "Okay."

But after a moment, he looked up and said, "There is this person, independent villa area, No. 41, facing Longchuan River."

Jin Jiahui and others breathed a sigh of relief: "Please take us there!"

Guo Lexuan patted Huang Ting's shoulder happily: "As expected of Old Huang, you still have some imagination."

Huang Ting opened her hand: "Stop it, I feel scared when you praise me."

Afterwards, led by the property manager, the group came to Villa No. 41.

The gate of the villa faces Longchuan River, and Jintang Restaurant is on the opposite bank.

There are flowers and plants planted in the villa yard, and the whole building has three floors in total.

Jin Jiahui took the key, inserted it into the door lock, turned it slightly, and the door opened.

In fact, there was a combination lock on the door of the villa, but they didn't know the combination.

Li Pinghai waved his hand to the old helper behind him and said, "Go in and search. Search thoroughly!"

Unlike what they had imagined, the villa looked luxurious from the outside. They thought the decoration inside must be magnificent as well, and were about to take a look at the drug dealer's luxurious residence.

However, the decoration in the villa is extremely simple, no different from ordinary rural houses, with very few home appliances and furniture.

Guo Lexuan went straight to the kitchen, took a quick look, and said to Jin Jiahui and Li Pinghai who were going upstairs, "This is it. The kitchen has been used, and there is half a chicken frozen in the refrigerator, and there are leftover onions, ginger, and garlic on the chopping board."

If Lin Chen and Luo Rui were here, they would know that this was the chicken soup that Zhang Yao made for her father Zhang Guangxia this morning.

The decoration on the second floor was slightly better, and it was obvious that someone had lived there before. There were women's clothes hanging in the closet of one of the bedrooms. Huang Ting looked at the size and nodded: "These clothes are suitable for Zhang Yao's height."

Then, a police officer in the study next door shouted, "Captain Li, we have a discovery here!"

Li Pinghai hurried over and saw a hidden panel in the bookcase. After the panel was removed, a huge metal safe was revealed!

Li Pinghai gritted his teeth and ordered, "Find someone to saw it in half!"

"Okay." The police hurried to arrange people.

At this time, Jin Jiahui went from the second floor to the third floor, but did not find anything useful.

There was very little atmosphere of life in the villa. There was no furniture on the first and third floors, not even tables and chairs. Zhang Yao's activities were only on the second floor.

So, Jin Jiahui went to the second floor to check. There were two bedrooms, a study, and an extra-large bathroom on the second floor.

The bathroom is separated into dry and wet areas. There is an extra-large bathtub behind the glass sliding door, which can accommodate two people taking a bath together. If you squeeze a little, three people can just lie down flat.

Jin Jiahui walked to the bathtub, squinted her eyes slightly, and looked at the items in the bathroom, including shampoo, shower gel, toothbrush, towel, etc.

At this moment, she heard a harsh cutting sound coming from the study.

Then, the police shouted: "Money, lots of money!"

"And a lady's pistol!"

Li Pinghai's voice came: "Don't move, take a picture first!"

Jin Jiahui turned around and was about to leave, but her eyes were suddenly attracted by the leaking hole in the bathtub.

At this time, Guo Lexuan ran to the bathroom door and shouted excitedly: "Senior sister, you have no idea how much money Zhang Yao has hidden? Can you make a bold guess?"

Jin Jiahui did not respond to her, but squatted down, put on disposable gloves, and picked up a round piece of object attached to the side of the hole.

Guo Lexuan asked in confusion: "What is this?"

Jin Jiahui took the thing in front of her eyes, looked at it carefully, and said thoughtfully: "Duckweed."

Guo Lexuan was very puzzled: "Why is there something like this in the bathtub?"

Jin Jiahui swallowed her saliva and said excitedly, "Call Mr. Luo quickly. I may have found the method by which Guanyin killed people!"
