According to the information of the developer and the property, there are 30 rooms in the seven units, three on each floor, with a total of ten floors, and the developer records that all 30 houses have been sold, and the property tells us that there are 30 owners in this unit.

The heart of the deceased was taken out in its entirety, that is to say, the murderer was very likely to be engaged in medical work, which narrowed the entire scope again, and I, who got the information of the thirty owners, analyzed the case of Liang Tao in the mobile command room: "The time of death of the deceased was at twelve o'clock at noon, and there were obvious strangulation marks on the neck, that is to say, there were two ways for the deceased to die, one was to suffocate to death, and the other was to strangle the deceased to death, but she was autopsied.

During the autopsy, the deceased woke up from pain, and then was killed alive, and during the whole process, the deceased's mouth should have been sealed, which is why when I examined the body, I found that there was an adhesive near the mouth, which should be the glue on the adhesive tape, which was left near the victim's mouth.

According to the signs that the deceased's atrium was taken out, the autopsy of the deceased should be a medical worker, who was very clear about the structure of the atrium, and when cutting, the technical means were very skillful and smooth, and the left atrium and right atrium of the deceased were all cut with a knife, and this technique could not be completed without the experience of the main knife.

Now that we have narrowed down the scope of the murderer, we can say that the target is self-targeted, because only the residents living here have doctors on the third, seventh, ninth and tenth floors, while the chief surgeon is only the family on the tenth floor, and the focus of the investigation is on the tenth floor. ”

"Okay, Comrade Tang Ming, the purple foreign body test result came out just now, it is polyvinyl chloride plastic, which is used to make hangers. Zhao Boan said.

"Let's go find it, that hanger should have been disposed of, if today's sanitation workers haven't cleaned up, they will definitely be able to find out." I said, "Say.

"At half-past twelve o'clock in the afternoon, it was time to clean up, and they had already collected and dumped the garbage. Zhao Boan looked at it a little embarrassed, I said.

This makes me completely stunned, what do you mean by this, it gives me a little headache, this is the most critical evidence, there is no whereabouts now, how can this be played, you tell me, it must be found, otherwise there is no way to prove the death evidence of the deceased: "Where is the place of dumping?" Since the tools of the crime were abandoned, it means that a piece was thrown away, go to find it, and order all the police officers to find it, there should be a scalpel, disposable gloves, disposable masks, purple hangers and a set of white clothes. ”

"Comrade Tang Ming, is this certain?" Zhao Boan said, staring at me uncertainly.

"If the murderer is a doctor, sometimes, they will adhere to professional habits, they may be a little paranoid, and they think that surgery is sacred, and they will definitely be dressed to carry out this crime, then these things must exist. I stared at Zhao Bo'an seriously.

"Okay, send someone to the garbage dump right away. Zhao Boan said.

"Well, you stay and go with our task force to meet these selected owners. "Ask Zhao Boan to stay, after all, this is a place in Donglin County, and with him, the director of the county public security bureau, some things are naturally justified.

All the owners who were notified before, but now they are asking for those suspicious families, all the registered owners have appeared, only four people, they are arranged separately, ready to be questioned by the task force, the resident on the third floor who came in first, named Hu Jianhua, is a cardiac surgeon at Donglin County Hospital of Traditional Chinese Medicine, this is a middle-aged man with a resolute look, and the whole person looks square.

"Hello, Mr. Hu, we are from the Donglin County Public Security Bureau. Zhao Bo'an, who was sitting there, spoke, his eyes were full of calm, and there was a hint of a smile on the corner of his mouth.

"Yes, Mr. Officer. Hu Jianhua glanced at Zhao Boan suspiciously, maybe he had recognized Zhao Boan's identity, but there were so many police officers at the scene, he was embarrassed to speak.

"May I ask where you are at twelve o'clock, what are you doing, is there anyone witnessed?!" I said, straight to the point, after all, there is not a lot of time, and if it drags on, it may have a greater impact.

"At twelve o'clock today I was on duty in the hospital of traditional Chinese medicine, and there were more patients in the cardiac surgery department at noon today, in order to treat these patients as soon as possible, our hospital let us the attending doctors work overtime. Hu Jianhua said that in his words, I did not find any loopholes, that is to say, what Hu Jianhua said in front of me was correct and there was nothing to hide.

"Check the situation. I gave Zhao Boan a look, and Zhao Boan began to arrange for someone to verify the situation.

Hu Jianhua's question is very simple, just a few words to ask clearly, when he bought this house, he came with a colleague, as for the specific name of the colleague was not revealed, but it doesn't matter, we also asked at the family at 12 o'clock, who was there, this Hu Jianhua also told us that the eldest son works in Jinling City, and the younger son is in high school in Jinling City.

In order to facilitate the care of the youngest son's studies, his wife has long been arranged to go to Jinling City, that is, in the Hu family in Donglin County, only Hu Jianhua is alone, generally he does not go home, eats in the hospital, and only goes home to sleep at night.

"Dog?" I asked, suspiciously.

"I heard the person who was bitten say that it saw our dog barbecing, and thought that whose barbecue was taken away by the dog, so I stepped forward to take a look, who knew that it was bitten, and I came back to deal with this matter. Hu Jianhua continued.

"Where do you keep your dogs?" I continued to chase, just because there was a ridiculous idea in my mind, if the murderer fried the heart and fed it to the dogs, what a perverted and cruel method.

The eyes are full of essence, and the truth of the case has begun to gather in my mind, this kind of disposal method is appropriate, and at this time, Hu Jianhua opened his mouth and said: "My dog is generally kept in the kennel downstairs, and I bought a piece of land from the property to raise this Laprado." ”

"What about the one who was bitten?" I continued.

"It was a homeless man in the neighborhood, and after I gave a thousand dollars, he left. Hu Jianhua replied.

"Well, there's no problem, thank you for your cooperation. I said.

Looking at the back of Hu Jianhua leaving, I reacted quickly in my mind and said: "Immediately go find the homeless man nearby, call up the community surveillance, you must find him, the heart of the deceased should be found." ”

"Tang Ming, you mean?" Liang Tao stared at me incredulously and said.

"Yes, it should be like that, the murderer fried the heart, fed the dog, no need to check, call up the community surveillance, and find the homeless man who was bitten by the dog. I said.

The dog was used to dispose of the evidence, that is to say, the heart may have been eaten, and now the person must be caught, but the questioning will continue, through the physiognomy, I can judge the murderer, the seventh floor, the ninth floor, the tenth floor walked in one after another, after a simple inquiry, I did not find anything unusual in several of them, that is to say, these owners may not have been involved in the killing, then their family, after investigation, the occupant on the seventh floor, the lover is also a heart surgeon.

It was the director of cardiac surgery in a neighboring county, and he was also a college classmate, at that time, it was already possible to judge what the murderer was, the director of cardiac surgery was called Ma Lijuan, and it was basically confirmed that it was her, the evidence of the homeless man and the surveillance video was being searched, and the murder weapon and so on were being searched, and the progress was basically smooth.

At three o'clock in the afternoon, the homeless man was found, brought back for interrogation, and at eleven forty he witnessed a woman throwing a piece of roast meat to a dog, and he was hungry for several days, so he thought about going up and grabbing meat from the dog, but he was bitten, and in the end he did not get any benefit, so he could only return in disappointment, and after he said this, the muscles of the deceased's body died completely at twelve o'clock, that is, the time of death of the deceased was earlier than twelve o'clock.

It's just that during this period, the deceased's muscles are active, and after the deceased is completely dead, he throws the body down, and when he leaves, he takes all the murder weapons out of the house, throws them in the trash can downstairs, and finally leaves the house calmly, this should be her murder process, so what about the motive for the crime, the identity of the victim has not been determined so far, and according to the later investigation, it is true that Hu Jianhua bought the house because Ma Lijuan's lover was a colleague in the same department as him.

The two families are very familiar, that is to say, that day Laprado was the person who knew the food, everything was in line with the basic logic, as time went by, soon all the murder weapons were found, as I guessed, when Ma Lijuan killed someone, it was regarded as an operation on the deceased, which is why when the deceased was killed, the murderer's calmness, presumably this psychological quality was completely raised on the operating table.

Hu Jianhua's news has also been confirmed, it is completely correct, the surveillance video has also been checked, and now the human and material evidence is complete, and the arrest operation can be carried out, Zhao Boan contacted the person in charge of the neighboring county, and after arranging the police, he began to carry out the arrest operation, this case does not have any criminal methods, it can only be said why, but now the motive for the crime with the identity of the deceased, everything has turned into a fog.

If you want to know the truth of this case, I'm afraid you have to wait until Ma Lijuan arrives at the case to know, for this motive for the crime, I am very curious, after all, there must be a reason for murder, not for no reason, and I, as the person who solved the case, naturally wanted to figure out this matter.
