Many onlookers outside the crime scene were tired of standing there, and left the KTV one after another. However,

the people from the Qingcheng Newspaper were still there, and even more people from other newspapers began to pour in, entering the KTV with press passes, standing outside the cordon, and trying to gather some explosive news.

Whenever a detective went in and out of the three private rooms, reporters would swarm around the cordon, asking questions at once, and the uniformed police had to physically block the reporters to prevent them from interfering with the work of the serious crime unit and the forensic department.

Because Nie Weiyan and his colleagues were the first to arrive, many of his newspaper colleagues who had good relationships with them tried to curry favor with them by offering them Marlboro cigarettes, hoping to get some information.

There was even a tabloid reporter who took out two pineapple buns from his pocket and asked Nie Weiyan and Joe with a smile: "You have been guarding here for a long time. Are you hungry? Come and try it. It's still crispy~"

Qingcheng Newspaper has always been in the middle and lower reaches of the industry. Joe and Nie Weiyan have never received such popularity and preferential treatment. It's really a bit overwhelming.

In a short while, they were chewing pineapple buns, drinking milk tea, and holding a brand new Marlboro. Their mouths were pried open and they didn't look serious at all:

"The police are in trouble this time!"

"What do you say?" Someone immediately acted as a supporting role.

"I have been writing news in Hong Kong for many years, and I have come across all kinds of cases. If a wife dies at home, then the murderer must be the husband; if a creditor dies, then the murderer is most likely the debtor; this time it is very serious, I will tell you, listen carefully. There are 16 suspects."

Joe stretched out his hands, gestured and spelled out a number of sixteen, and then continued with an expression of praise:

"Everyone is a suspect, isn't it? Some of them are trying to steal the deceased's girlfriend; some of them are trying to steal the deceased's job opportunity; some of them are drugged and raped by the deceased; some of them are the deceased's subordinates, which makes people cry and feel sad. They are ordered around and scolded every day, and they are bullied and can't hold their heads up as men; some of them are spread rumors by the deceased privately, and they are in a bad mood every day. When they were drinking with others, they said they wanted to kill people. You say this deceased is powerful or not, let's sing together, wow, 16 enemies are in this private room!"

Joe clapped his hands, clicked his tongue and shook his head, sighing for a long time before he was willing to continue speaking under the anxious eyes and urging of others:

"When we arrived, the detectives hadn't arrived yet. I secretly saw the scene firsthand, haha. The deceased was right there, with the weapon stuck in his body and there was no need to look for it. The knife was so polished that you could tell who was killed, and there was not a single fingerprint. 16 people said that they didn't see anyone else go to the deceased, and they didn't know who killed the deceased. They were all innocent. There were footprints and fingerprints of everyone at the scene. What should the police do? Are they going to arrest all 16 people? Without clues and witnesses, how do you say they can solve this case?" "

Is this true? Are you kidding us?" Some people thought it was too evil and didn't believe it.

Joe, however, looked calm, with a frown on his face, which clearly said "believe it or not", making the others half-believing and half-doubting, not knowing how to write the manuscript.

But seeing the solemn faces of the detectives coming in and out, they did believe it a little.

"Then how long do you think it will take to solve this case?" someone else asked.

"It can't be solved. In my opinion, those 16 people are all murderers, and they are covering up for each other, so you will never catch the murderer. The law is not responsible for everyone. Even if the police officer finds out, there is no evidence. It's difficult." Joe shook his head and vowed.

"This is an unbeatable murder case!" someone commented.

Joe pondered over this sentence and thought: Using "This is an unbeatable murder case" as the title is a good choice.

Nie Weiyan couldn't help shaking his head as he listened to Joe's mixed truth and lies.

But even if the case was not what Joe said, it would not be easy.

It took almost an hour for the forensic science department to search for evidence, and the body has not been transported back to the police station yet. This only shows that the clues at the scene are very complicated. The police are still not sure whether they have completed all the information that needs to be investigated at the scene, otherwise the body should not be here at least.

It seems that this case is indeed difficult to deal with. I wonder how long they have to wait after they go back and write the beginning of the case before they can report that the case is solved. Or

, can they wait until that day...

Although it is called the Supreme Box, and although it is indeed the largest box in this KTV, it is not very spacious for 16 people. The room was full of traces left by the sixteen people playing around, and the KTV owner couldn't possibly take the cleaning work so seriously. In addition to these 16 people, there were also many traces left by previous guests - because when the case happened, only these 16 people and the deceased were in the room, and the other miscellaneous traces had to be ruled out in the end. The more Chen Guangyao investigated, the gloomier his face became. Xu Junhao had wanted to take the body away a long time ago, but the Forensic Department kept asking for additional clues, so he had to wait while completing all the inspections that could be done on the scene as soon as possible. The atmosphere in the room was very depressing. Everyone tried not to talk if they could, and they all buried their heads in their work with a heavy heart. "What is this?" Yi Jiayi suddenly pointed to the deceased's watch. "You can't even recognize your watch?" Chen Guangyao approached and stretched his sore shoulders. "No." Yi Jiayi nodded at Chen Guangyao, signaling him to take a closer look. Fang Zhenyue heard the noise and also came over to check. Everyone came closer and carefully checked, and then they found a golden brown hair stuck on the watch of the deceased. Because it was almost exactly the same color as the skin of the deceased, it had not been discovered. Chen Guangyao hurriedly waved to the technician, who immediately came over with an evidence bag, carefully removed the hair with tweezers, and stuffed it into the bag. After it was installed, the technician spoke: "There is a hair follicle, which can be tested." "If no one else approached the deceased after he lay here, then this hair is very likely to belong to the murderer." Fang Zhenyue stood up straight and continued: "If the deceased's watch was caught by this hair somewhere else, it would most likely fall off during the movement. And the position where it is stuck on the watch is very good. We can assume that when the murderer leaned over to kill the victim, it was the last time the victim's body moved automatically. He may have felt severe pain and wanted to struggle, but could not control his body, so he only moved very slightly. Look carefully at the wine stains on the table--" As he said this, he pointed to a mark on the table towards Chen Guangyao and Yi Jiayi. "This stain was left on the deceased's cuff when he drank before he fell into a coma, so the stain was left when his sleeve rubbed against the table, right?" Yi Jiayi immediately responded.

"Yes, it is very likely that the murderer's hair was on the victim's arm when he committed the crime, and a strand of hair fell into the watch strap. The victim's last subtle movement just caught the hair." Fang Zhenyue pointed to the table, "There is also alcohol on the victim's arm. We can assume that the murderer has long brown hair, and the hair ends on the left ear may still be stained with alcohol."

"I'll go collect evidence now." A technician from the Forensic Department immediately expressed his opinion.

Chen Guangyao nodded and sent two people to the next door to check the hair of the sixteen people.

Ten minutes later, the Forensic Department finally took the bodies away.

Colleagues from the Forensic Department checked the hair ends of the five long-haired women, and three of them had liquid on their hair ends. They had to be taken back to the laboratory technician for testing to determine what these liquids were.

Fang Zhenyue led the team to a vacant small box for a meeting. After preliminary matching, they found out the footprints of the deceased going back and forth twice, the footprints of the deceased touching the ground at the table, long brown hair, liquid on the hair, sitting at the edge so that it was convenient for her to walk towards the deceased, etc. Finally, the arrow pointed to a 27-year-old woman named Zheng Lishan.

"Zheng Lishan is 162 cm tall and weighs about 100 kg. She is a copywriter in an advertising company and a subordinate of the deceased. Other colleagues have a good opinion of her, saying that she is cheerful, works diligently, often has good ideas, and has good writing skills.

"She has always respected the deceased and cooperated with the deceased's superior's requests for overtime and redoing. Colleagues say that they have never heard her complain about anything and that she is a very enthusiastic person at work.

"There has been no conflict with the deceased.

"But some people said that when the deceased promoted his subordinates to supervisors a month ago, he promoted another man instead of Zheng Lishan.

"Many people feel sorry for Zheng Lishan, saying that Zheng Lishan is obviously more capable and the deceased just looks down on women and always suppresses Zheng Lishan."

Liu Jiaming said while reading the confession:

"It seems that the deceased discussed Zheng Lishan when she was not around, saying that women do not have any work, they will go home to have children sooner or later, and there is no point in getting a promotion, and she is not needed to support the family.

"These kinds of words should have reached Zheng Lishan's ears, but colleagues said that Zheng Lishan just smiled and never got angry about it. She is a very generous and good-tempered woman."

"She is a smart woman, but unfortunately she chose the wrong way to solve the problem. "Lin Wangjiu shook his head and snorted, obviously he had already identified Zheng Lishan as the murderer.

"Is she so cunning? She didn't show it at all, but she quietly planned to kill?" Liu Jiaming frowned, a little bit unbelievable, a woman who looked so cheerful and gentle, so harmless, could actually be deadly? "

Now the clues are not enough. All the clues point to her, but if there is no way to prove that she is the murderer, she still can't be convicted." Fang Zhenyue nodded to Sanfu, "Take Jiaming with you, and take Zheng Lishan to the small room and interrogate her alone. "

"Yes, sir! "Sanfu received the order and responded in a very serious manner, then walked out of the box with Liu Jiaming.

In the eyes of the onlookers, Sanfu's expression was particularly imposing, as if revealing his determination to make the murderer confess.

The door of the box was closed again, blocking out the backs of Sanfu and Liu Jiaming, as well as the prying eyes of the reporters.

Lin Wangjiu looked at Fang Zhenyue and sighed, "Wait a little longer, the forensic investigation will be over, and it's time to let the others go."

Now the suspect must be identified as soon as possible, otherwise they will all be let go.

"The murder weapon was at the scene, but no fingerprints were left. The confessions of everyone present could not reveal any clues about the murderer, and when the KTV waiter entered the private room to deliver something, no useful information was found... How about we wait until Sanfu and the others have finished questioning Zheng Lishan before considering the next step?" Gary felt that his brain cells had been squeezed to the limit and he could no longer think of anything useful.

"The Forensic Department has not found the thing that covered the handle of the knife when the murderer killed people. "Yi Jiayi frowned and tried hard to recall.

She clearly saw that thing in the mind flow image.

The murderer Zheng Lishan used a piece of cloth to hold the handle of the knife to kill people, so there were no fingerprints on the handle.

But the colleagues in the forensic department did not find any clues of the cloth on the handle. There were no thread ends and no pressure marks on the cloth.

Jiayi only saw thick white cloth in the mind flow image. There seemed to be no special shape. What

could that piece of cloth be?

"If it is toilet paper, after wrapping the handle with it, the outline of the handle will definitely be printed. Even if it is crumpled into a ball in the end, the outline and blood stains will be found after it is spread out. But all places in the box have been checked and nothing was found. "Fang Zhenyue frowned. With the case at this point, can they only hope that Zheng Lishan will confess?

But would a smart person who was ready to kill someone but didn't show any hatred, and who had calculated everything clearly, confess during the police interrogation?

"She wouldn't really eat the paper that might have stained the victim's blood, right? That's too cruel." Gary's expression gradually twisted, and he even felt a little disgusted in his stomach.

"No, my colleagues in the Forensic Department have just checked the toilet paper provided by the KTV. The quality is very poor, and if you rub it with a little force, a lot of tiny paper scraps will fall off. There were no such scraps of paper by the victim's table, which means that the murderer didn't use the paper here to wrap the knife handle. "Fang Zhenyue added:

"The Forensic Department has also checked the tissues brought by other people, and they will also leave more or less paper scraps after wiping things.

"And, judging from the blood around the body, when the knife was inserted into the body, there was first a diffuse spray of blood, and then vertical dripping of blood. Before the murderer took away the thing wrapped on the handle of the knife, that thing must have been stained with a lot of blood."

Fang Zhenyue took a deep breath and swallowed dryly, then he realized that he was thirsty. He frowned and tried to hold it back. Just as he was about to continue, Yi Jiayi handed him a bottle of mineral water from somewhere.

He nodded, opened the bottle and took a sip before continuing:

"We have all used tissue paper and know that it will see through water if it gets a little wet. According to the amount of bleeding the knife caused when it was inserted, calculated by Forensic Doctor Xu, wrapping it with four or five layers of tissue paper may not guarantee that there will be no marks on the handle.

"And now the handle is so clean that there is no clue. It can only mean that she either wrapped it with a lot of hard paper that does not shed any crumbs at all, or it is a piece of thick enough cloth."

Yi Jiayi quickly wrote it down. She felt that Sir Fang's reasoning process was extremely precious. She would study it carefully when she returned, and not miss a single word.

"In that case, it is impossible to eat it." Gary frowned and asked, "How about taking Zheng Lishan to do an X-ray? "

The murderer should have had more careful considerations. Since she prepared a knife in advance, she must have thought of a way to hide her fingerprints in advance. She should not have forced herself to eat a lot of thick paper or cloth that was difficult to swallow. Especially walking around with such things, it would be too conspicuous." Fang Zhenyue lowered his eyes and looked at his palms. The fine lines on his palms were crisscrossed like a myriad of intricate clues.

He had to find the most core and most important clue, it must be hidden somewhere!

"What could have been completely overlooked by us?" Yi Jiayi looked at Fang Zhenyue's notes and asked casually with frowns.

Fang Zhenyue suddenly froze, turned his head and stared at Yi Jiayi, his long eyes were like cold knives, emitting a cold light that seemed to be able to hurt people without being seen.

The young policewoman was startled, but the man said, "Go on."

"Ah... the book says that when the police are collecting evidence, they should focus on capturing unusual clues. For example, a tilted TV, a kitchen knife on the living room table, a photo frame on the table, or an expensive bag in a poor family... All these things that 'shouldn't be here' and 'seem to have been moved' may become clues, so the police must pay attention to them when investigating a case..." Jiayi didn't quite understand what Fang Zhenyue wanted to hear her say, so she could only sort out her thoughts and mutter to herself.

Fang Zhenyue, however, seemed to have heard some particularly useful information. He suddenly raised a finger and nodded:

"So, what is it that is in that box that the police won't notice?"

Yi Jiayi looked at Fang Zhenyue, and a light bulb suddenly lit up in her head. Some important clues overlapped with Fang Zhenyue's words.

In the flow image, the thing that was held in the murderer's palm and wrapped around the handle of the knife, some inconspicuous features were magnified!

"It's something from the KTV! It's already in the store, and every private room has it!" Jiayi slammed her palms on the table and said uncontrollably:

"I know!"

...

Fang Zhenyue and Yi Jiayi were talking to each other in the private room, getting louder and louder, speaking faster and faster, the mood was high, and the atmosphere was just right, but...

Lin Wangjiu and Gary looked left and right, feeling like they understood, but not completely.

After all, Uncle Jiu was more experienced. Following Yi Jiayi's words, he kept scanning the private room they were in. Although it was much smaller, the decoration was the same as the crime scene.

The thick golden lace was draped over the bright red sofa. It looked a bit earthy now, but it would definitely look magnificent under the lights.

This KTV shop is well decorated and expensive. Everything is high quality. Even the soft furnishings such as tablecloths and curtains are very sophisticated and thick.

So, what Yi Jiayi and Sir Fang meant was that the murderer used fabric from the KTV box to wrap the knife handle?

But the sofa cover, tablecloths, and curtains are all very large. That definitely won’t work—

is that possible?

As Jiayi slammed the table and stood up, Uncle Jiu also thought of something and stood up and ran out.

Fang Zhenyue hurriedly stopped her: “Pay attention to your image!”

There were reporters outside!

The door was pushed open, Yi Jiayi looked back at Fang Zhenyue, grinned and stuck out her tongue, then turned back to face the police and cameras outside the cordon on the other side of the corridor, with a blank expression on her face, acting solemnly and seriously.

Lin Wangjiu was not lazy at all. He walked beside the little policewoman, striding through the corridor and into the supreme box opposite, looking majestic.

Fang Zhenyue walked at the end, looking at their backs and not knowing whether to laugh or cry. In the camera of the reporters, only this sergeant looked the most casual.

As soon as Yi Jiayi stepped into the KTV, she found the seat where Zheng Lishan was sitting according to the seating chart drawn by her colleagues in the forensic department, and then her eyes fell on the white microphone on the table in front.

The handle of the microphone was covered with a thick red lace cloth cover. The luxurious details even to the microphone reflected the attitude of this KTV.

"Brother Tony, the evidence bag!" Yi Jiayi looked at the microphone and was excited but did not dare to reach out easily for fear of contaminating the evidence.

Lin Wangjiu also guessed that Jiayi was talking about this thing. He stood by and watched Tony run over. He hurriedly cooperated with Jiayi to instruct Tony to remove the cloth cover.

Even if the red cloth cover was stained with blood, it would not be easy to see. Tony compared the cloth cover with the knife handle and found that it was a perfect fit.

Wearing gloves, he carefully turned the cloth cover inside out. The inside of the cloth cover was white and was stained with blood.

Chen Guangyao also ran over to look at the blood stains and said excitedly, "It's it! It's it!"

The light shone down and took a closer look. Some traces could be seen without collecting them. "Tony, collect fingerprints first!"

"Yes!" Tony immediately took the tools and carefully collected fingerprints.

Fang Zhenyue stood by with his arms crossed, watching Yi Jiayi with a red face, sometimes giving instructions and sometimes concentrating.

The inspector, who had a frown just now, now looked relaxed.

"Jiayi found it?" Chen Guangyao looked at Tony collecting fingerprints before looking up and asking Yi Jiayi.

"Yeah." The little policewoman grinned shyly. She wanted to laugh proudly, but she was a little shy. However, her eyes were sparkling and she couldn't hide her sense of accomplishment.

Chen Guangyao understood this look. When a person is doing something that he thinks is meaningful and has achieved even a little success, he will show this look.

What a passionate and active little policewoman.
