Li Mu's case is a suicide at first glance, and the body will be returned to the family after a simple examination and the time of death is confirmed, and a detailed autopsy will not be done, let alone an autopsy or the like.

The police station naturally has its own rules and regulations, except for homicides, the body will not be kept in the police station for too long, that is to say, if you want to leave the body in the police station to continue the investigation, the only way is to find out the problem in this case, and transfer the case that has been characterized as suicide to the criminal case of homicide, otherwise the body will inevitably be taken away by the deceased's family in the end.

Ding Fan didn't have nothing to do, he had to find a little problem in this case, and finally made a murderer out of the original simple suicide case to add to the blockage.

In fact, in Ding Fan's heart, there is really a little hope for the existence of a murderer, after all, the current investigation of the case has not been very optimistic, if there is such a person, then pry open the murderer's mouth, and there will definitely be a lot of detours.

But objectively, Ding Fan doesn't want such a murderer to exist, because once such a person really exists, I'm afraid it will not be easy to solve this case.

So in Ding Fan's heart, this kind of contradictory thoughts have been constantly fighting in his mind, and even arguing so much that they are almost inseparable.

And Mi Xiaomi's pacification work is not very smooth, Ding Fan has already been to the forensic office downstairs once, obviously still busy over there, a lot of trace comparison has not been completed, these tasks also need a specific time to produce results.

It's just that looking at the situation on Mi Xiaomi's side, it seems that it can't be supported anymore, it is not easy for the old couple to raise their son, and suddenly heard that their son committed suicide, and the sadness in his heart can be experienced, and it is obviously not easy to calm them down at this time.

"A person from the immediate family, preferably a father or mother...... It's still my father!"

In fact, this kind of thing, whether it is a father or a mother, there is not much difference, originally Ding Fan still wanted to ask the old couple to go together, and it was good to say goodbye to his son.

But seeing Li Mu's mother, who was already crying out of breath at this time, Ding Fan stood in place and thought for a while, and finally chose his father to take a look, otherwise Li Mu's mother would be in this state later, and he would not be able to support it.

Li Mu's body was lying on the cold decomposition table, the body had been cleaned up, and it was said that if the body wanted to be thoroughly examined, not even hair could be left on the body.

In this way, the deceased's external injuries can be observed more directly, but in view of the state of Li Mu's death, as well as the suicide note he left at the scene, it has basically been judged as suicide.

At this time, Li Mu's face was slightly blue, his lips were faintly purple, and a strangulation mark at the bottom of his neck extended to the position behind his ears, and there were no traces of crossing on the back of his neck, which also ruled out the possibility of being strangled behind him.

There are basically not too many marks on the limbs, and although there are some scratches on the neck, the scratches on the neck are not very serious because of the problem of nails.

In fact, the corpse at this time is already good, the corpse I saw at the scene before was not so neat now, the deceased's eyes were not closed at that time, his eyes were round, and his face was covered with snot and saliva.

If Li Mu's father saw his son's appearance at that time, I am afraid that he would not have the opportunity to cry like now, and it is possible that eighty percent of them will die of fainting on the ground because of excessive sadness.

In the process of the old man crying bitterly, Ding Fan stood aside without saying a word, just quietly accompanied him, handing over a piece of toilet paper from time to time, or pulling a chair behind him, for fear that he would fall to the ground.

As early as a few minutes ago, Meng Huan had already brought someone over, seeing that the deceased's father was here, she didn't say anything, just stood and watched from a distance, after all, she only didn't know that it was more appropriate to come over and say something at this time.

It wasn't until the old man's body really had no way to support it, he sat on the chair behind him, covered his face with his hands and cried quietly, Meng Huan walked to Ding Fan's side and asked: "Master, the corpse is not autopsied, we are afraid that there are many things that cannot be determined, for the time being, no pinholes have been found on his body, there are no external injuries, and all our suspicions have no way to be verified!"

Ding Fan naturally knew this, but looking at the appearance of this old man, it is probably not a simple matter to get him to agree to a detailed autopsy.

"Have you shown the suicide note written by the deceased to your family?"

Meng Huan has been busy since she came back, and there are some things that Ding Fan doesn't remind her, and it is estimated that it will take a while to remember.

"Suicide note, didn't you give it to Lao Hu just now?" Meng Huan reached out and grabbed his hair, sighed and said: "The trace examination department has extracted the relevant evidence, and the rest has been sealed in a bag, and it will be transferred to the evidence department later, and after the body is handed over, the relics of the deceased will be returned to the family." ”

Ding Fan thought about it, and hurriedly frowned and said, "Take the things back immediately, and show the family if there is any change in the handwriting!"

Although Meng Huan didn't understand what Ding Fan meant by the change, Ding Fan opened his mouth, and he naturally took action to do it immediately.

Ding Fan looked at the suicide note in his hand, walked to Li Mu's father, and asked in a low voice: "Uncle, this is the suicide note we found at the scene, please see if it is Li Mu's handwriting!"

"I know it's really cruel to tell you about this at this time, but I don't think you want your son to die so inexplicably, I'll tell you the truth, Li Mu's suicide ...... I have suspicions, but the current situation is a bit troublesome, on the surface it seems that he committed suicide, unless your family agrees, otherwise we have no right to deal with this autopsy!"

Thinking about it, Ding Fan felt that he couldn't wait at this time, although it was a little cruel, but he still had to make a decision immediately, while the body was still in his hands, he had to make some attempts at anything, only in this way, the matter of detailed autopsy could be settled.

And Li Mu's father, when he heard that his son's suicide seemed to be suspicious, the whole person froze, took the suicide note in Ding Fan's hand with trembling hands, and said while reading it: "I know you also mean well, but I'm a stupid boy in my family, I have loved beauty since I was a child, and no one is anymore, so I just want to tell him to go clean and beautiful, I really don't want to call him ...... It's ......"

Before Li Mu's father finished speaking, the words in his mouth suddenly paused, as if he saw something, and then the tears in the corners of his eyes fell again.

Ding Fan walked up to him and glanced at the suicide note in his hand, not quite understanding what he meant.

"This is indeed written by my son, and he was taught by me since I was a child, and I can see it at a glance, but it is just ...... The word "filial piety" of this "filial piety" looks a little wrong, he often misspelled this word when he was a child, and he often wrote the following "son" as "Yu", I didn't expect that this time he finally learned it. ”

Ding Fan took a closer look at this word, frowned and picked up the magnifying glass on the side, magnified the word several times, and said in surprise: "Uncle, look at it, he still hasn't written this word correctly, it's not that he deliberately wants to correct it, but when he was writing, his hands trembled, and the two were connected together, and there were some signs of irregular trembling on the other words." ”

As Ding Fan spoke, he handed the magnifying glass in his hand to Li Mu's father and said, " When he wrote this suicide note, eighty percent was frightened, or he had already thought that after he wrote this suicide note, his life was likely to end, so the uneasiness in his heart caused his hands to be a little disobedient, in the whole suicide note, most of the words are very round, I think he should have deliberately practiced words before, but there are a few words he wrote very stiff and the last stroke, he wrote very hard, almost cut the paper!"

After hearing Ding Fan say this, Li Mu's father finally discovered something wrong, but with these things, he was still a little reluctant to ask him to agree to the examination of the corpse!

And this, Ding Fan also thought of it, walked aside, reached out and rummaged among a pile of evidence, took out an inconspicuous small bag and said: "I have seen your son's hands, he should have a habit of biting his fingers, right?"

Although there were no bite marks on Li Mu's fingers, Ding Fan found that this kid's fingernails were not very smooth, looking long and short, as if he had been gnawed by a dog.

This situation is actually very common in some kindergartens, and some adults, although they have grown up, they tend to maintain the habit of childhood, and when their nails grow a little, they will subconsciously bite off the nails on their fingers with their teeth.

And this small action, Li Mu's father naturally knew, but he didn't understand why Ding Fan asked like this, and nodded with questions on his face.

Ding Fan handed him the small bag in his hand and said: "This is what I found in the room, after checking, the nails are Li Mu's, and the position of his fingers, it is obvious that someone has cleaned his nails before, not only cut off the nails, but also repaired the edges and corners on them very smooth, but the strange thing is that I searched all over the scene, but only found a small piece of nails, even if the nail clippers were not found, the other nails were not found!"

Li Mu's father has worked in the meat factory all his life, and he can't say that he has any great achievements, but his brain is not stupid, as soon as he heard Ding Fan's words, he immediately thought of something, and asked in surprise: "Do you want to say that before my son died, someone appeared and even cut his nails?"

"Except for your son, someone must have appeared before at the scene!" When the two of them were talking about this, Qin Lu walked out of it with a document in his hand and said: "I checked the internal locks and other appliances in the room, and only found Li Mu's fingerprints at the scene, it is said that there should be no superfluous people at the scene, but when I finally checked the doorknob, I found that there was not a single fingerprint on the doorknob." ”

"Hear me clearly, a person's fingerprints don't exist, not even Li Mu's fingerprints, this is obviously unrealistic, unless someone opens the door for Li Mu and still has gloves on his hand, or when someone leaves, they clean up the fingerprints on the door lock, but accidentally clean up Li Mu's fingerprints together!"

With Qin Lu's proof, it can almost be concluded that at the scene of Li Mu's death, there were indeed biological traces of a person, but this person had been hiding and didn't want anyone to discover his existence.
