The butcher rushed back to the bureau overnight, wave after wave of unsettled, one after another bizarre murders, the butcher couldn't sit still, and informed us to go to his office after the autopsy, the deceased's autopsy actually did not have many places to do, the cause of death and the method were clear at a glance, I asked Chu Tianqi to write the autopsy report, and went to see the butcher with Yun Duruo.

When we entered the office, Ling Guodong was already in the room, the butcher kept walking back and forth in the room with his hands on his back, Tie Qing had no words for a long time, his expression was no longer angry but solemn anxiety.

"Smoke." The butcher stopped in front of me and said only one word.

I was stunned for a moment, and then realized that the butcher should have been in such a hurry that I forgot to change my police uniform, and hurriedly handed him the cigarette, and he snatched the lighter as soon as he took it out.

"Are the results of the field exploration out?" The butcher asked Ling Guodong while lighting a cigarette.

"Two completely different blood stains were found in the bathtub at the scene, and the results of the laboratory tests have come out, the blood stains that have been wiped in the room are Mu Hanzhi's, and the latest one is the deceased." Ling Guodong reported calmly.

"What else did you find?" The butcher asked grimly.

"In addition to the blood stains found in the bathtub, residual sulfuric acid was also found, and the bathtub was identified as the first crime scene, the deceased was killed in the bathtub, and the body was also disposed of in the bathtub." Ling Guodong said seriously. "But there are very few new blood stains in the room, and only a few were found on the ground at the scene, mainly in the bathtub, which shows that the murderer is extremely skillful."

After hearing this, the butcher silently walked back and forth a few steps, took a deep puff of the cigarette in his hand, and finally stopped in front of Ling Guodong.

"What about Mu Hanzhi? What are the results of the bloodstain identification about her? ”

"Mu Hanzhi's blood stains are mainly distributed in the bedroom, and there are traces of blood splashing on the wall, through the experiment, Mu Hanzhi should have been attacked by a heavy object and caused blood to splash everywhere." Ling Guodong replied seriously.

"Judging from the bloodstains left behind, did Mu Hanzhi die at that time?" The butcher raised his head and asked with a serious look in his eyes.

"In the bloodstains, especially in the blood splashed on the walls, there was cerebral medullary material on the surface of the assay, in which gray matter from the cerebral cortex and cerebrospinal fluid residues were found." Ling Guodong said to the butcher with certainty. "It can be seen that the heavy object that attacked Mu Hanzhi directly damaged her skull, and also hurt her brain, Mu Hanzhi should have died at that time."

The butcher heard the cigarette in his hand shake slightly, stood in place sluggishly, and it took a long time to come back to his senses, sigh heavily, and slowly walked to my side, looking at me and Yun Duruo, his voice was a little regretful and guilty.

"I didn't expect you to be right, I have been doing criminal investigation for so many years in vain, and I have always thought that there are no unjust, false and wrongful cases under my hands, Mu Hanzhi was characterized as suicide by me, and stubbornly thought it was right, I always thought that you were misled...... I didn't expect that the misguided person was me from beginning to end, but Mu Han died in vain for twenty years, and the truth is only revealed today. ”

The butcher has never been a person who refuses to bow his head, but he didn't expect him to have a remorseful expression, and he couldn't see the slightest pretentiousness, which was completely self-blame from the bottom of his heart.

"It's because the murderer was too cunning, and the criminal investigation technology at that time was not as advanced as it is now, so you don't have to blame yourself too much." Yun Duruo pursed his lips and said.

"If you are wrong, you have to admit it, not to mention that human life is at stake, and it is not an excuse that the murderer is too cunning, it can only prove my incompetence." The butcher said categorically without any sense of relief. "Anyway, since it is certain that Mu Hanzhi was killed by him, it is my fault that she was wronged in twenty years, but now what we have to do is how to make Mu Hanzhi sink her grievances, if it takes twenty years to give her justice and bring the murderer to justice, I believe she can also die blindly."

The butcher said this, turned his gaze to me, and asked solemnly.

"How's the autopsy going?"

I reported the process and findings of the autopsy to him in detail, and the butcher looked even more solemn after listening to it, perhaps because the murderer was too arrogant and cruel, presumably he had seen such a murder method for the first time after so many years of criminal investigation.

"No internal organs were found in the body of the deceased, but considering that the deceased was corroded by sulfuric acid, the murderer should have waited until the flesh and blood of the deceased's epidermis were completely decomposed, and then removed the internal organs, leaving only one heart in the skeleton." I deliberately singled out this finding during the autopsy.

"Only one heart left?" The butcher took a deep puff of his cigarette and glanced at me. "Any idea what's the point?"

"The murderer seems to have deliberately left the heart, and after corroding all the muscles and flesh of the deceased, it seems that he deliberately left it for everyone to see." I thought thoughtfully about the answer.

Someone knocked on the door outside, and it was Chu Tianqi who came in, and he was very surprised to see his expression, and said to us after coming in, after Yun Duruo and I left, he sorted out the autopsy report, and when he wrote about the heart, he found that the heart seemed to be a little strange, perhaps because my attention was all on the bones of the deceased at that time, and I didn't pay attention to the remaining heart.

Chu Tianqi judged that the heart seemed to be a little smaller by comparing it with the skeleton of the deceased, and the results of the test surprised all of us.

The heart left in the skeleton of the deceased is not human.

It's a dog's heart.

"Dog's?!" The butcher was stunned and looked at Chu Tianqi who came in suspiciously.

I frowned and thought of the deceased's only intact head left, and my eyes suddenly lit up.

"Human-faced beast heart!"

Yun Duruo and the butcher both looked at me when they heard this, and I did not hurry to say my reasoning, the murderer did not leave in a hurry after the murder, but moved the deceased to the roof of the building and erected it in the shape we saw.

The place where the deceased died was the bedroom in Mu Hanzhi's room, and it was also the place where Mu Hanzhi's bones were disposed of twenty years ago, and the roof was the place where Mu Hanzhi jumped off the building, both of which were related to Mu Hanzhi, and the murderer seemed to have deliberately associated the deceased with Mu Hanzhi.

And if the murderer is simply committing murder, he can kill the deceased in a very simple way, but judging from the murderer's method of committing murder, the murderer is more inclined to revenge and vent anger, so that in the end, the deceased is erected to announce the meaning of the world.

Beastly!

This is the murderer telling everyone what kind of person the deceased was.

"Heartbreaking!" The butcher took a puff of his cigarette, and it seemed that he accepted my inference. "It's lawless, Yun Duruo! How's it going on your side, has the deceased been identified? I'm going to see what a man with a human face and a beast's heart is. ”

Yun Duruo had already received feedback from the people sent out to investigate before coming in, the identity of the deceased had been determined, the deceased's name was Nian Weimin, male, forty-seven years old, a businessman, mainly engaged in the sales of building materials, extremely strong assets, and social interactions were very messy, and the specific situation continued to follow up.

Ling Guodong also reported to the butcher in a timely manner, and the forensic department extracted Nian Weimin's footprints, and compared them with the four footprints found at the scene, confirming that it was one of them, on the night Mu Hanzhi died twenty years ago, among the four people who appeared in Mu Hanzhi's room, Nian Weimin was among them.

"What about the other three footprints?" The butcher looked back at Ling Guodong and asked eagerly. "Have you identified who it is?"

"Nope!" Ling Guodong shook his head regretfully. "After all, it was omitted twenty years ago, if it wasn't for the discovery of Nian Weimin's body, it would not have been possible to find out that one of the footprints was his so quickly, as for who the other three are, only Nian Weimin can be used as a breakthrough to investigate."

After listening to this, the butcher slowly walked back to the desk, tapped his fingers on the tabletop, and said meaningfully after pondering for a long time, the footprints left by twenty years ago are undoubtedly looking for a needle in a haystack if they are really to be traced now, but the murderer killed Nian Weimin in Mu Hanzhi's room, and then hung his body outside to make it public, indicating that he did not want to hide it, and it can be seen that the murderer intended to let the police know that Nian Weimin was one of the four people in the room that year.

I nodded and agreed with the butcher's inference, and it is not difficult to see through the autopsy that the murderer's methods and processes are to let us know a little, this is revenge!

"Oh! That's right! Ling Guodong suddenly remembered something and hurriedly said. Of the four footprints found, one of the footprints was female, in addition to the already confirmed Nian Weimin. ”

This discovery was a bit unexpected, Mu Han stopped interacting with fewer people, and our attention and focus had always been on the mysterious man who had never been seen, and we never thought that there would be a woman involved in the murder twenty years ago.

The butcher listened to the debriefing in silence and walked back to me.

"You're in charge of the autopsy, and I'd like to hear your thoughts." Transcript: Wonderful

I rubbed my forehead and sorted out my thoughts and replied, judging from the murderer's means of committing the murder, the murderer has professional anatomical knowledge and an extremely good understanding of the human body structure, and it cannot be ruled out that he is a medical practitioner.

And among the several recent murders that have occurred one after another, such as the first unnamed female corpse dismemberment case, Su Fengmei's murder case in the secret room and Nian Weimin's murder case, these three cases all involve knowledge of autopsy and surgery, and from the habits and details of the murderer's crimes, these three murders seem to have been committed by the same person.

And the deceased are more or less related to Mu Hanzhi, among the people who have intersected with Mu Hanzhi, there is only the man with the smell of formalin mentioned by Zhou Baiman, Zhou Baiman said that Mu Hanzhi has no quarrel with the world, and has almost no contact with men, so she can argue with him, that person is likely to be Mu Xiaoxuan's father.

"Is there such a possibility, Mu Hanzhi died in vain, maybe this man knows the truth and has been planning for twenty years, and now he is starting to take revenge!" I'm going to make bold assumptions.

The people in the room were all lost in thought, and seeing that they all more or less agreed with my reasoning, the butcher sat back in his chair, rubbed his tired cheeks with his hands, and spoke in a heavy voice.

"Is this man not the most important thing, since it is revenge, there are four footprints in the room, the night Mu Hanzhi died twenty years ago, there were four people present, Nian Weimin was one of them, and now he is dead, if it is really like what you said, this is revenge...... Wei Min's death that year was just the beginning! ”
