"Heh, it's the first time I've gone to a place where any high-tech equipment can't come in handy, and in such a big room, we may have to see two claws to do it manually." Liu Jie felt helpless in the face of the ruins that had been burned by the fire.

"The smell of gas belies what used to be in the room, and I can't make an accurate judgment." Chen Yanxi was also unable to make a judgment on the scene.

Mu Haoran's eyes swept over the two of them, and after glancing at them, he began to inspect the scene, Liu Jie and Chen Yanxi pursed their lips and didn't dare to say anything to refute, so they had to do the survey seriously, not wanting to be found fault by Mu Haoran.

After gradually walking to the bedroom, Chen Yanxi found the body of a carbonized contracture on the bed that was still burning out of the bedroom.

Chen Yanxi opened the inspection box that she took from the car parked in the garage, handed the camera to Liu Jie, and distributed gloves and masks to everyone.

Liu Jie looked at Chen Yanxi incredulously: "I used to know that the elder Chen Jingye was the most dedicated, why didn't I find that our little Yanxi is the most dedicated, this toolbox is carried with me." ”

"This is my habit, in case someone is outside, isn't it too wasteful to go to the team to get tools when there is a case?" Chen Yanxi put on a mask and went to work, after which she stopped talking to everyone, she had a clear distinction between work and life, and she should devote herself to thinking about the case at this time.

Mu Haoran picked up the metal wreckage left by the burning of the electric fan from the ground, the plastic part of the fuselage has been completely burned, only the non-combustible metal fan blades and grille remain, and the scorched jack on the wall not far from the fan is the scorching marks left by the electric fire after the short circuit that the firefighters said.

But a simple circuit fire should not have caused a gas explosion in the room so quickly, he remembered very clearly, he had been standing by the window at the time, and he had already noticed it when there was a fire outside the window, and before that, it had been dark from the window of Chen Yanxi's house to the floor facing the crime, so why did the explosion occur so quickly, was the gas leaking before?

But Mu Haoran didn't believe in this inference, he didn't believe that these two conditions would be met at the same time at the same scene, there was a gas leak and then the wires were short-circuited, which seemed to be a bit too much of a coincidence, but vaguely felt that things were not as simple as they appeared, maybe this was a premeditated murder, but the deceased on the bed was clearly a child, who would do such a murder to a child?

"Boss, come and take a look." Du Jiang of the Technical Investigation Department found some information and asked Mu Haoran to come and take a look.

"What's wrong?" Mu Haoran walked over and asked.

Du Jiang picked up a small piece of rubber on the ground that had not been completely burned with tweezers and handed it to Mu Haoran, and asked mysteriously: "Boss, what do you think this is?" ”

Mu Haoran took the tweezers and observed them carefully, and said, "It's like rubber particles." ”

Du Jiang gave a thumbs up: "Good eyesight, but to be precise, this is the insulating rubber skin particles on the power line, and you look at the cut on this, this is a neat cut with scissors or knives, I guess that the short circuit of the indoor wire is someone who did something on the power line." ”

Mu Haoran snorted coldly: "It's really murder!" ”

Du Jiang shook his head: "Not necessarily, it depends on the results of Yeon-hee's autopsy." ”

"Eight or nine is not far from ten." Seeing this rubber and plastic particle, Mu Haoran had already confirmed his judgment in his heart, and the autopsy was just a stamp on this determination.

He then walked up to Chen Yanxi again and asked, "Did you find anything?" Did he kill? ”

Chen Yanxi raised her head slightly and glanced at him, then lowered her head and began to work, after a person is burned to death, there is often a part of the surface of the corpse that will not be completely burned, at this time she is gently decomposing the residual clothing fabric tissue of the carbonized corpse that is not completely exposed to the air.

At this time, her movements must be gentle, her movements are as light as if she is flicking a feather, because the burned corpse is very fragile, and a little force will destroy valuable undamaged body tissue.

Chen Yanxi put the stripped fabric tissue in the evidence bag and sealed it so that it would not become brittle and damaged by exposure to too much air, and after half an hour, her autopsy was nearing the end of the work, and she beckoned to take the body away.

"He killed?" Seeing her movements, Mu Haoran already had an answer in her heart.

"The deceased was between 8 and 10 years old, a female child, and based on observations at the scene, it was preliminarily judged to be homicide." Chen Yanxi said.

"Why?" Mu Haoran asked.

"Three obvious characteristics, the first point, the state presented at the scene of the fire shows that the deceased was cremated after death, the burned person will have obvious life reactions in the event of a fire, even the sleeping person will have a slight limb reaction, can reach the state of charring of the whole body, the muscles contract violently under the heat force, and the limbs will show a fist fighting posture, but the deceased did not, she lay upright on the bed, without the slightest trace of struggle or shouting."

"Second, the most obvious feature of the burned person is that on the eyes, due to the stimulation of a large amount of smoke, the victim reflexively closes the eyes, and an unblackened 'goose feather' reaction will be formed in the outer corner of the eye, called the outer corner of the eye fold, and there will be charcoal dust in the fold. When the eyes are closed, the tips of the eyelashes are burned, and the inner eyelashes remain, which is called eyelash syndrome, which the deceased did not have. ”

"The third point is that the reaction is on the deceased's respiratory tract, if the deceased is burned to death, then if she still has respiratory function, then under the action of heat, her respiratory tract will be damaged. A large amount of dust generated at the fire scene will deposit the mucous membrane surface of the respiratory tract of the deceased, but you see, there is only a little smoke attached to her mouth, nose and throat, but for the people at the fire scene, this is inevitably too clean, congested, bleeding, necrosis, nothing. ”

"Very good, very comprehensive." Mu Haoran listened very carefully, he was a layman for trace examination and autopsy examination, and he was humbly writing down the words of several colleagues, or his master, so as to carry out better work in the future.

The police who came after receiving the police carried the girl's body onto the stretcher, but at this time, Chen Yanxi made an unexpected discovery, he called the police who were covering the girl's body with a cloth: "Please wait a minute." ”

The police didn't know why, but they still slowed down the movements of their hands, Chen Yanxi turned the girl's body over with the help of another policeman, and when she saw those traces, Chen Yanxi shook her head again and again: "How can this be?" ”

"What's wrong?" Mu Haoran saw that her expression was a little wrong, and hurriedly asked her.

"How can you be so cruel, how can such a young child provoke others and use such a cruel way." Chen Yanxi was already sweating on her forehead, and she couldn't believe that someone would be so mad.

"What the hell is going on?" Mu Haoran's heart was suspended.

"She was electrocuted to death and then cremated." Chen Yanxi pointed to the marks on the girl's body and said.

"Is it this mark?" Mu Haoran saw the small hole according to her guidance.

"Yes, this is an obvious electric shock injury, there should be other parts, but the corpse was severely charred and carbonized to cover up those traces, my God, what's wrong with people now, how can I be willing to give such a black hand to a child." Chen Yanxi put her hands in her hair, and her emotions were a little broken.

Mu Haoran pressed her shoulder: "You are now a case officer, you have to control your emotions." ”

Chen Yanxi pursed her lips to prevent her tears from falling, and after she sorted out her inspection tools, she said: "My work is done, I will leave first, notify me after contacting the family, and I will conduct an autopsy." ”

Mu Haoran nodded and agreed: "You go home first, take a shower, relax, calm your emotions, the family hasn't rushed back yet, it is estimated that you can't do it tonight, you rest early." ”

The people who participated in the on-site survey left the scene one after another, and Mu Haoran also fell into a short contemplation before evacuating, yes, what kind of car hatred in the space can make people so viciously strangle a teenage child, he is not a ruthless person, seeing this scene, his heart is not better than Chen Yanxi, but as the leader of a team, as their leader, he has to choose to be strong.

What everyone is curious about is that until everyone left, the family members of the deceased did not go home, Mu Haoran, who stayed in the office to rest, looked at his watch, it was already nine o'clock in the evening and no one had come to claim the body, which was too unusual.

Time blink of an eye to the next morning, a whole night passed, and Mu Haoran still did not wait for someone to claim the body, which was beyond his expectations.

He called Li Duo, who had been in charge of guarding the periphery yesterday: "Tell me about the situation when you visit the periphery tomorrow, it is impossible for such a young child to live alone, where is her family." ”

Li Duo took out the notebook he was carrying and reported to Mu Haoran: "Boss, I'm also very surprised by this, the residents on this floor actually said that this little girl is often at home alone, and even often spends the night at home alone, saying that it is because her parents are very busy with work, what institute they are working in, there is no elderly at home to help take care of the child, and it is helpless to let the child stay at home alone, the child's parents seem to be on a business trip in the past two days, and they also threw a few hundred yuan to the neighbor's aunt before leaving, Say yes and let her take care of your child if she needs it. ”

"Two adults just left the children at home by themselves?" Mu Haoran felt that this was a big joke, it was still a teenager, no matter how independent the child was, parents would not dare to go on a business trip together so reassuringly.

The aunt said that it was not easy for these two couples, they both grew up together in an orphanage, were admitted to college together, worked together, worked hard in Beihai for many years to save such a house, and this was also out of helplessness, and the house had to repay a lot of loans every month, which was forced by the economy. Also, according to the residents downstairs, a man bought a lot of food and toys yesterday and went to the girl's house, and the man asked them about the floor where the girl's family lived, saying that he was taking care of her for the girl's parents, but no one saw the man at the time of the crime. ”

Li Duo reported everything he learned yesterday to Mu Haoran, but it sounded too unbelievable, and it felt too irresponsible for parents to ignore their children's safety so much.
