Chapter 48 File
Coal Ash behaved particularly well this time.
As soon as it entered the house, it lay obediently on the carpet in the middle of the living room, as if it knew not to disturb Xia Mufan while he was doing his work.
When Gu Shaoqi sat back on the sofa, the coal dust rubbed against his feet. It quietly raised its claws and touched the pair of dark blue cotton slippers. Seeing that Gu Shaoqi did not refuse, it began to scratch boldly.
Hearing Gu Shaoqi say let's go, Meihui stood up without hesitation, first jumped onto the coffee table, and then jumped onto Xia Mufan's shoulder.
Xia Mushi patted its furry paws and said, "Solar Ash, let's go back."
Soot Gray meowed twice in response.
[Go back, go back.] 】
What's so good about turtles? They're just stupid. 】
[Is Forensic Doctor Gu a little sad?] 】
Coal ash was very smart. When it heard Xia Mufan calling Gu Shaoqi "Forensic Doctor Gu", it followed suit and started calling him "Forensic Doctor Gu". As for what forensics is, it has no idea.
Cats perceive human emotions through their sense of smell, and they can tell that Gu Shaoqi is not happy just by smelling it.
Xia Mufan looked at Gu Shaoqi who walked straight to the entrance to change his shoes.
He was very tall, wearing a white shirt and black pants, looking thin and upright. But his movements seemed to be held back by something, and appeared to be a little slow.
For some reason, seeing Gu Shaoqi like this made Xia Mufan feel a little stuffy in his chest.
Perhaps, it's sympathy?
Xia Mufan found his missing mother and had coal ash as company again. In comparison, Gu Shaoqi was much more miserable. His relatives passed away suddenly, the murderer is still at large, and the only person around him is a stupid grass turtle.
Back at the Criminal Investigation Team, Xia Mufan waved goodbye to Gu Shaoqi and Zhou Wei, and whispered to Meihui, "If you're okay, stay with Forensic Doctor Gu."
When Coal Ash heard this, he became anxious.
[Xia Xia, I am your cat! 】
How can you let me accompany someone else? 】
Xia Mufan was both angry and amused, and tapped Meihui's nose: "Don't you go to his place to bask in the sun when you have nothing to do?"
Soot licked her fingertips and bared his teeth ingratiatingly.
[That’s different!] 】
How can it be the same that I want to go and you ask me to go? 】
You know what, Coal Ash's IQ is really higher than that of ordinary people.
There is nothing wrong with it going to find others to play with on its own, but if the owner lets it go, it means the owner doesn't care about it and wants to push it to someone else.
For coal ash, this is a prelude to “abandonment”.
Xia Mushige said: "Of course you are mine, and I will never abandon you. It's just that it's pitiful to take care of the forensic doctor alone, so I'm sending you a task."
Coal Ash's face immediately turned from gloomy to bright.
[Is this a mission?] That's fine. 】
[Is there any reward for the mission?] 】
Xia Mushige nodded: "Of course. If you perform well, I can agree to one condition of yours."
Coal Ash's eyes rolled around as he pondered over what conditions he should propose.
[It’s a deal!] 】
[Don't lie to cats.] 】
After getting Xia Mufan's approval, Meihui jumped off Xia Mufan's shoulder, ran into the corridor, and the cat disappeared in an instant.
Xia Mufan pushed open the door of the Serious Crime Unit 7 office.
As soon as Feng Xiaoyu saw her, she couldn't wait to ask, "How is it? Did forensic doctor Gu provide any new clues?"
Xia Mufan spread his hands and said, "Forensic Doctor Gu raised a tortoise. This tortoise was indeed at the scene when the crime happened. It's a pity that tortoises don't have vocal cords. At most, they can make some noises when breathing through their nostrils, but they can't speak at all."
Thinking of Zhou Wei's face that was almost twitching from trying so hard to hold back a smile when he left, Xia Mufan felt speechless. I guess Zhou Wei would never believe that he could hear the thoughts of the grass turtle Xiao Mo, right?
Feng Xiaoyu stamped her feet: "You are still in the mood to joke! Even if the tortoise has vocal cords, can it speak like a human? I thought you were really here to look for clues, but I didn't expect..."
Gong Weiguo shook his head, with a hint of sympathy in his voice: "It's over, it looks like Forensic Doctor Gu will be sad and sleepless for several days."
Xia Mufan looked at Gong Weiguo: "Insomnia?"
Gong Weiguo sighed, "You have not been in our criminal investigation team for long, and many things about Forensic Doctor Gu are still unclear. At the beginning, Captain Yue led us to reopen the old case and invited Forensic Doctor Gu to review it together. However, we reviewed it again and again, but to no avail. Everyone is a little anxious and irritable. Forensic Doctor Gu looks like nothing happened on the surface, and he comforts us not to worry, but in fact he is under the greatest psychological pressure. I heard from the nurse at the health center that Forensic Doctor Gu needs to be prescribed sleeping pills before he can fall asleep."
Xia Mufan frowned. The harm caused to Gu Shaoqi by the murder of his parents was probably beyond her imagination.
Although she experienced the disappearance of her mother when she was young, firstly, children recover quickly; secondly, she is open-minded and gets angry when she is angry, unlike Gu Shaoqi who keeps it in her heart; thirdly, she has the cats and dogs in the village to keep her company, so she is mentally healthy.
But Gu Shaoqi is like this... Thinking of how his eyes turned from bright to dim today, and his slightly heavy steps when he sent her back, Xia Mufan frowned: "Then let's try not to alarm Forensic Doctor Gu when we reopen the old case this time."
Feng Xiaoyu nodded heavily: "Okay, let's get started?"
Gong Weiguo pushed out a mobile whiteboard, took out a blue marker, and wrote the words "October 18 Major Case" on it.
Yu Jing and Sun Xianbing had just sent their car in for maintenance, and before they could even catch their breath, they had to attend a meeting again. They raised their hands and signaled, "Wait a minute, let's have a drink of water first."
Gong Weiguo said with a serious expression: "It's okay, just drink some water while listening, it won't delay anything. You two have never participated in the investigation of the October 18th case before, so you still need some familiarity. Xiaoyu and I will tell you the main points first."
Yu Jing and Sun Xianbing listened to the general idea in the car, but they were not clear about many details and could not make any suggestions, so they nodded and said, "Okay, then you go ahead."
Feng Xiaoyu took out the photos of the scene from the files and hung them on the whiteboard one by one.
Gong Weiguo pointed at the photo and began to introduce.
"The main factory staff housing was built in the 1970s, and is nearly 20 years old. There are three units in South Building 6. Each unit has no door, and there is a yard on the first floor. There is a single-flight staircase from the first floor to the second floor, and a double-flight staircase from the second floor to the third floor."
Feng Xiaoyu added: "This means that anyone can come in directly."
Xia Muchen looked at the old buildings in the photo and knew that the overall economic level in the 1970s was not high, and the wages of ordinary people were almost the same. The requirements for anti-theft were not high, and there was no design for unit doors.
Gong Weiguo pointed to the photo of the door lock and said, "The factory area has good security. The old residents did not install anti-theft doors. The front door of the Gu family is an ordinary wooden door, and the door lock is an old-fashioned bull head lock and a double-safety pin lock."
Feng Xiaoyu said: "This kind of door lock is not difficult for a skilled thief to pry open. A piece of wire can pry the door lock open. The keyhole was found to have been damaged during the on-site inspection, which shows that the thief pried the door open."
Xia Mushige raised the first question: "Is it possible that the other party used a key to open the door and then picked the lock before leaving?"
Feng Xiaoyu asked in confusion: "If you have the key, why bother picking the lock?"
Gong Weiguo slapped his thigh excitedly and said loudly, "It's possible! The other party deliberately set up a maze to make us mistake it for a thief. Team leader Xiao Xia, you asked a good question. From now on, the three of you just ask any questions, no matter how incredible. We are too familiar with this case and may have a fixed mindset. But this is your first time dealing with this case, and everything is new to you."
Xia Mufan signaled Sun Xianbing to take notes: "Okay, write it down first, and we can discuss it together later."
Sun Xianbing raised the pen in his hand and said, "Okay, I'll write it down. Weiguo, please continue."
Gong Weiguo pointed at a few photos and began to explain: "This is the Gu family's living room, connected to the front door. The shoe cabinet is placed in the stairwell. After opening the door to the living room, there is a fabric sofa on the left hand side, and a coffee table in front of the sofa. There is a window on the south side, and there is a TV cabinet under the window. There is a 21-inch domestic color TV and a fish tank next to it. There is a turtle in the fish tank."
At this point, Feng Xiaoyu pointed to the photo of the fish tank and said, "That's the grass turtle. Xia Xia should have seen it at Forensic Doctor Gu's house, right? If you hadn't told us, we wouldn't have paid any attention to it."
It's just a turtle. So what if it saw the murderer? So this grass turtle was treated as a background and the serious crime team collectively ignored it.
Xia Mufan could see clearly that the tortoise that was hiding in its shell and not daring to move was Xiao Mo: "Turtles are very smart. If it saw the murderer, it might react more violently."
Gong Weiguo shook his head: "I've never heard of anyone using a turtle to solve a case."
He glanced at Xia Mufan, who had a serious expression, and changed the subject: "However, let's give it a try. If you want to give it a try, it's not impossible."
Feng Xiaoyu glared at him and said, "What do you mean by trying everything possible? That's too ugly."
Gong Weiguo shrugged: "Otherwise, who would believe me if I asked the turtle for clues?"
Xia Mufan raised his hand and said, "Let's stop talking about this topic and continue."
Gong Weiguo paused, and after explaining the layout of the living room and bedroom, he began to show photos of the corpse.
Looking at the cold photos, everyone present felt heavy in their hearts.
Gu Mingkang was stabbed in the ventricle by a sharp object and then pulled out. The ventricular muscles are strong and the wound closes automatically. There is no large amount of bleeding. The blood flows into the pericardium, causing the heart to be unable to relax and the heart to stop beating. Without blood supply from the heart, humans will lose consciousness within a minute and die within a few minutes.
Xie Lijiao suffered a severe blow to the back of her head, resulting in a contusion and laceration of her scalp, a depressed fracture, and subarachnoid hemorrhage, and she immediately fell into a coma. The carotid artery is cut open by a sharp weapon and is completely severed, causing blood to gushed out. The brain suffers from ischemia and fainting in an instant, leading to death within a few minutes.
It was the first time that Yu Jing saw such a brutal murder scene, and his face turned pale.
Sun Xianbing had seen some crime scene photos in college, so he wasn't frightened. But when he thought that the cold bodies in front of him were Forensic Doctor Gu's parents, he felt a chill down his spine.
Yu Jing said in a trembling voice: "What hatred, what grudge, would you kill someone like this?"
Sun Xianbing shuddered: "This doesn't look like an ordinary thief. He's so efficient. Is he a professional killer?"
Gong Weiguo stood beside the whiteboard and pointed at Sun Xianbing. "Xiao Sun is right! We think so too. However, Captain Yue and his team spent money to send informants to find the killer organization, but none of them met the requirements of being 176 cm tall, weighing 70 kg, and being able to shoot with both hands. In the murder case files of the past few years, no criminals with similar methods were found. If they were professional killers, how could they only commit this one case?"
Sun Xianbing was encouraged and spoke out what he was thinking: "If it was a burglary, and the owner discovered it and attacked and injured someone, the purpose was usually to escape, not to kill. In this case, at most, there would be a few random stabbings and cuts, the wounds would be disordered, and there would be traces of a scuffle at the scene. Gu Mingkang and Xie Lijiao would definitely shout for help when they resisted. The apartment building has poor sound insulation, and it would definitely wake up the surrounding residents. It is impossible for it to be as quiet as this case."
Gong Weiguo gave a thumbs-up gesture and said, "Okay, Xiao Sun. You're right. This case is indeed not like an ordinary burglary."
Sun Xianbing: "Since this is not an ordinary burglary, then it must be a revenge killing?"
Feng Xiaoyu sighed: "But we checked Gu Mingkang and Xie Lijiao's social relationships several times and found no problems."
Sun Xianbing reacted quickly: "Could it be that forensic doctor Gu provoked an enemy?"
Gong Weiguo walked over from the whiteboard and stood in front of Sun Xianbing: "Forensic Doctor Gu was still studying in Kyoto at that time. How could he have made any enemies?"
Sun Xianbing said: "He has good grades and looks good. Could it be that a high school girl had a crush on him but failed, and her love turned into hatred? Or was he competing with his classmates, which aroused jealousy? Or maybe he met some psychopath in college who wanted to kill his whole family?"
Gong Weiguo shook his head: "No, no, no, forensic doctor Gu was born, grew up and studied in the chemical factory. His living environment is very simple. The parents of factory children are all colleagues, and the neighbors are all friends. In summer, the company issues popsicle tickets, and in winter, the company issues cotton-padded jackets. Fruits and meat are issued all year round. Every family has enough food and clothing, and no one needs to envy anyone. As for academic performance, that is not a problem. Those who can study can pass the exam, and those who can't study can go to the factory's technical school or secondary school, and go to work in the factory after graduation. Everyone has a good future, and no one needs to be jealous of anyone.
We didn’t know before that the welfare benefits at Daxi Chemical Plant were so good. Even during the ten years of the movement, the chemical plant was like a small paradise, self-sufficient. There is not only a school in the factory, but also a gymnasium, a dance hall, a cinema, and an ice rink. Children have a key hanging around their necks and run around happily as soon as school is over. There are familiar people everywhere, so there is no need to worry about getting lost. ”
Hearing this, Sun Xianbing said, "So, Forensic Doctor Gu was really happy in the past."
The five members of the Serious Crime Squad sighed at the same time.
The almost perfect youth was suddenly met with such a change. The gap was too big and no one could bear the pain.
Feng Xiaoyu said, "When he was young and ignorant, forensic doctor Gu did have a lot of girls who liked him, but those were all very innocent feelings. At that time, forensic doctor Gu only cared about studying, going to college and becoming a doctor, and he didn't respond to those feelings. The girls might be a little unwilling, but it's not the case that he would kill someone because of hatred caused by love."
Sun Xianbing continued to analyze: "Well, if it is unlikely that Forensic Doctor Gu has made enemies, then it can only be a problem on his parents' side."
After a pause, he listed the possibilities.
"Although Gu Mingkang's parents don't have much contact in the north, is it possible that they left an inheritance? Are the brothers and sisters worried about Gu Mingkang's share of the inheritance?"
"Xie Lijiao is a local and has many brothers and sisters. She is now working in a chemical factory with good benefits and a happy family. Is it possible that her brothers and sisters are jealous and killed her out of anger?"
"Or, Gu Mingkang's work is related to chemical technology. Is it possible that he may have involved top scientific research results and was discovered by spies, who sent people to assassinate him?"
Gong Weiguo and Feng Xiaoyu have participated in the reopening of old cases several times, and all the possibilities that Sun Xianbing thought of have been considered by everyone.
"Gu Mingkang's parents are employees of a steel mill in J City, Shandong Province. Their ancestors were all poor peasants for three generations, both red and professional, and there were no problems with their background checks. They have two sons and one daughter, and Gu Mingkang is the third child, with an older brother and an older sister. Both his brother and sister work in the steel mill, are filial to their parents, and have a harmonious family. Before his parents passed away, Gu Mingkang rushed back to his hometown, and handled the funeral properly without any disputes. This can be confirmed by the relatives, colleagues, and friends of Gu Mingkang's parents."
"Xie Lijiao's parents are farmers. They have six children. The eldest and second are sons, Xie Lijiao is the third, the fourth and fifth are daughters, and the sixth is a son. It is very difficult to raise so many children in the countryside, and the family is relatively poor. Xie Lijiao ran away from her marriage to work in the factory. After marriage, she rarely interacted with her family, only bringing some money back during the New Year and other festivals, so she was not very close to her brothers and sisters.
When we went to the village to investigate, some people said good things about Xie Lijiao and some said bad things about her. However, according to our observation, except for Xie Lijiao who graduated from junior high school, the rest of the Xie family only finished elementary school and stayed in the countryside to farm. In the late 1980s, rural people with free time went to work in the city, and after earning money they returned home to build houses. The economic conditions of each family were pretty good. The Xie family members are all honest people. When they see the police, they are like quails and do not have the courage to kill people and rob them. ”
"We have also investigated the technical research that Gu Mingkang is engaged in. It is not a national research project, and there is nothing that can attract the attention of spies. Gu Mingkang's technical team has a total of seven people, and Gu Mingkang is the person in charge. Gu Mingkang does not care about fame and fortune, and he is fair in his dealings. Everyone gets along very well."
With this said, it seems that the environment in which Gu Mingkang and Xie Lijiao live is harmonious, without a single conflict.
At the end, Gong Weiguo gritted his teeth and slammed his palm on the conference table: "Damn it! Who is the murderer? Why did he kill Gu Mingkang and Xie Lijiao? Why did he hide so deeply?"
Xia Mufan had listened to most of what he had said, so he slowly stood up and glanced at everyone: "That's enough for the introduction of the case. Now let's start the deduction of the crime process."
Gong Weiguo was very familiar with the deduction process. He smiled bitterly, picked up a pen and a triangle ruler from his desk, and said to Feng Xiaoyu: "Come on, I will play the murderer and you will play Xie Lijiao."
He turned to Yu Jing and said, "You are about the same height as Gu Mingkang, so you can play him."
When Sun Xianbing saw the crime scene being reenacted for the first time, he was very excited and his eyes were full of eagerness to try. He looked at Xia Mufan and grinned: "Xiao Xia, we are the audience."
Xia Mushige nodded: "Yes, we are the audience. We can stop at any time and raise questions at any time."
Gong Weiguo held a triangle ruler in his left hand: "This is a hammer." He held a pen in his right hand: "This is a dagger."
Feng Xiaoyu drew a few lines in the empty space of the office with chalk: "This side is the living room, and this side is the master bedroom."
Gong Weiguo stood at the door of the "living room", Feng Xiaoyu and Yu Jing stood in the "bedroom", and the three were ready to start the performance.
Xia Mushige suddenly shouted "Stop!"
