◎Chapter 22 Human Mop

What the man said was: mopping the floor!

The blind old man was surprised, this man was not a neighbor, and he had not heard his voice before.

What a strange thing it is for a stranger to mop the floor in an unfamiliar hallway at night.

The old man was vaguely worried about the blind girl who lived next door, and he was worried all night, how he hoped that the blind girl would appear safe and sound the next day.

Early the next morning, Bao Chu and Hua Long arrived with a team of police, and found a female corpse at the corner of the stairs - the blind girl had been killed.

The police immediately cordoned off and secured the scene, and the female forensic doctor soon drove in. She carried a steaming bag of xiaolongbao in her left hand and a plastic bag in her right with cartons of milk, which she had bought from the roadside downstairs.

The female forensic doctor said: Let's eat something, eat well and work, your special case team won't see the corpse and can't eat, right?

Hualong pinched a small long bao, stuffed it into his mouth and asked, "Will the inquest take a long time?"

Bao Chu said that he was not hungry, he pointed to the blood stains in the corridor and said: In the morning, it is estimated that the investigation work will not be completed, and the murderer has cleaned up the murder scene.

"Murder scene" refers to the place and place where criminals commit murder, dismemberment, concealment, burial, and scattering of corpses and body parts. Due to the different mentalities, experiences, motives, goals, means, and environmental conditions of the criminals, the scene of a homicide case is quite complex, and each homicide scene has its own characteristics.

Some murderers are calm and calm, and instead of fleeing the scene as soon as possible after the killing, they clean up the scene of the murder and erase their traces.

The characteristic of this homicide case is that there is a lot of blood.

There are blood stains both indoors and outdoors, and they are widely distributed. Bloodstains are not only traces of the murder scene, but also physical evidence, which has very important criminal evidentiary value and identification role.

Bao Chop has to take pictures of every drop of blood for evidence, which is a lot of work.

The female forensic doctor measured the temperature inside and outside the room and the anal temperature of the corpse, the blind woman was wearing autumn clothes and pants, the first scene was in the house where she lived, combined with the blood stains on the pillow on the bed, it can be judged that she was killed by cutting her throat in her sleep. The female forensic doctor measured the length of the single-edged knife wound of the sharp object, and she said to the dragon: This murderer is as strong and powerful as you, from right to left, with a single swing, this woman's neck is almost broken.

The dragon walked up to him and asked, "What's the matter with the blood on the roof and on the ground?"

The female forensic doctor raised her head and said: Splash formation, if a person is beheaded, the blood can be sprayed as high as a two-story building.

In the homicide scene investigation, the blood spatter analysis method can infer the state of the victim at the moment of blood splattering from the shape of the blood stains at the scene. If the blood is in the form of round droplets, it indicates that the victim was at rest at the time; If the blood has a "tail", it indicates that the victim is in a state of movement.

Bao Chu made a crime simulation, and Hua Long visited the next-door neighbor, and after the on-site investigation, Bao Chu and Hua Long made a detailed report to Professor Liang.

The murderer was a man, male, and the window of the deceased's room was not equipped with guardrails, and the murderer used a glass knife to cut through the glass and enter the deceased's room through the window. The murderer held a knife in his right hand and killed the blind girl in her sleep. The blind girl's blood splattered onto the roof, and it rained blood, and the killer cleaned up his bloody footprints in a shocking way.

Professor Liang asked: How was it cleaned up?

Draw the dragon and say: human mop!

Bao Chop said: An ingenious and bold way to clean up.

The murderer grabbed the legs of the female corpse, stood upside down, and slowly retreated, as if mopping the floor, dragging off the bloody footprints on the ground with the hair of the deceased. Dragged from the room to the corridor, in the corridor of the corridor, the murderer happened to meet a blind man

The old man, claiming that he was "mopping the floor", deceived the past. Drop the female corpse at the corner of the stairs and flee the scene.

Professor Leung: The murderer came prepared, bold and careful, why didn't he kill the blind old man?

Drawing Dragon: The murderer may have seen that the old man was blind, and in addition, the danger of committing murder in the corridor is relatively high.

Professor Leung: The blind woman is a witness, and the murderer may not know that she is also blind.

Bao Shu: According to the visit, the blind girl has only been working in this massage clinic for a few days.

Professor Leung: The two words that the murderer said - mopping the floor, are they Mandarin or local dialects?

Draw the dragon and say: Mandarin.

Prof. Leung: Immediately survey the patients who have been to that clinic, focusing on Mandarin speakers. The murderer was supposed to have gone to the clinic to get a massage before, and he dragged the body and passed by the old man in the hallway, without killing him for a reason, because he knew that the old man was blind.

Not many local residents spoke Mandarin, and the scope of the investigation was greatly narrowed, and a list was soon drawn up. Recently, there are only five patients who speak Mandarin at the clinic for the blind: a truck who often goes to gua sha cupping to devour the driver, a lawyer with a herniated lumbar disc, a migrant worker who sprained his foot to do orthopedic massage, a female accountant who has done neck and shoulder massage, and a retired veteran cadre who spent fake money at the blind clinic and was recognized.

Blind people have a particularly keen sense of hearing and a very good memory. According to the old man's recollection, he was unfamiliar with the murderer's voice and did not seem to have been in contact with him before.

Bao and Hualong went to the door one by one according to the addresses on the outpatient medical records, and some of the addresses were very vague, and it was very difficult to check and visit, and it took time to find them. Professor Liang requested that the information of the patient's family should also be obtained during the investigation, because the patient is usually sent to the clinic by the family, and the murderer may be one of them.

Professor Leung asked Su Mei to go to kindergartens, primary schools, infant clinics and children's playgrounds to post posting notices in front of the search for people in the know. The forensic examination proves that the deceased woman had a history of childbirth, and the deceased had children, so she will definitely go in and out of the above-mentioned places, and as long as someone knows or has seen the deceased, the true identity of the nameless female corpse can be decoded.

A few days later, a heavy snowfall fell on the city. The special case team worked tirelessly and ran around all day, and finally made a major breakthrough in the case.

A young woman who had seen the deceased told the police about a strange story: the young woman's baby often vomited, and the young woman took the baby to a baby clinic for medical treatment. In the courtyard of the clinic, she chatted casually with a woman in a white down jacket with red hair, and when she glanced at it, her hair stood on end, and the young woman saw the woman holding the child and exchanging parenting experiences—a doll wrapped in swaddling clothes!

It was almost dark, and the young woman was so frightened that she left immediately, and when she got home, she told her husband about this strange thing. A few days later, she saw a notice in front of the clinic and immediately called the police.

Bao Shu: After dark, where did the deceased go?

Su Mei: At night, it's scary enough to hang out on the street in white, and then get red hair and a fake doll in your arms. God, it's scary to think about.

Prof. Leung: The deceased had children, and it is likely that the children died young, and their spirits were stimulated.

If so, the deceased has been disbelieving that his child is dead and living in a fantasy.

Professor Leung asked the young woman to cooperate with the portrait expert to draw a portrait of the deceased's face. Bao and Hualong immediately visited the baby clinic to investigate. Unexpectedly, the owner of the clinic looked panicked when he saw the police, he lied that he was not a doctor, but also a patient, and quietly wanted to slip away under the pretext of going out to make a phone call. Draw a dragon to subdue him and bring him back to the city bureau for interrogation.

Long: When you see the police, what are you running for?

Clinic owner: I'm scared, I've been beaten before.

Bao Shu: How many years has your clinic been open?

Clinic owner: Five or six years.

Hualong: Is there a "Medical Institution Practice License"?

The owner of the clinic argued: My doctor's license will come down this year.

Bao Shu: Did you see the notice posted in front of your clinic? Do you know the woman above?

Professor Liang didn't say a word, and suddenly took out a few photos and put them in front of the clinic owner. When the boss saw the female corpse in the photo, he was so frightened that he almost fell out of his chair. During interrogation, the key points should be highlighted, and the suspect's psychological defense line should be completely destroyed, so that the suspect can honestly explain the problem.

This black clinic was opened by the owner and his wife, who are not qualified to practice medicine, but because of the cheap price and the large number of patients, there are still many people who come to see the doctor. It was banned once due to a doctor-patient dispute, and then it was quietly opened. A few years ago, a woman surnamed Yun brought her child to this clinic for treatment, and after taking injections and medicines, she returned home and the child died unknown. Ms. Yun gathered nearly 100 relatives and friends to come to the clinic to ask for guilt, crying and fussing, and smashed the clinic like crazy. Later, under the mediation of the police station, the owner of the clinic compensated a large amount of money, and Ms. Yun gave up. Unexpectedly, after a few years, Ms. Yun was mentally stimulated and came to this clinic again.

The owner of the clinic said: Alas, I was scared to death at that time, she was holding a fake child in her arms and asked us to give her child an injection.

Bao Chop: How many times has she been to the fake doll?

Clinic Owner: I remember three times, once when she was dragged away by her husband, and once again, she wandered around the courtyard without entering the door.

Su Mei: Do you have children, do you also see your own children?

Clinic owner: Yes, boy, 10 years old. It's been a few years since this happened, and I've lost money, why do you think she's still doing it, her child died at home, which is our responsibility? Now, this woman is dead again, but it has nothing to do with us.

The identity of the nameless body was confirmed, and according to the address provided by the owner of the clinic, the special case team found Ms. Yun's home.

Ms. Yun runs a housing agency and her husband is a surveyor for the Forestry Bureau. After the death of their son, the couple's relationship broke down, and neighbors confirmed that they often quarreled and divorced many times.

Ms. Yun's home is a small courtyard by the street, and there is a hut with rental information written on the wall, the courtyard door is closed, and there is a pair of children's shoes on the concrete floor in front of the door. After Bao Chop took pictures for evidence, Hualong planned to enter and open the door, and the snow fell on the wall, and Hualong stood on it, but never jumped down.

Bao Chop asked below: What's wrong?

Draw the dragon and say: Bring the camera.

The snow had stopped, and there was a clear line of small shoe prints on the snow in the courtyard, and the police found the body of Ms. Yun's husband in the house. A forensic autopsy revealed that the man had died of poisoning, and that he had washed bloody clothes in the bathroom and a chainsaw. The results of the inquest confirmed that Ms. Yun was killed here, there were no traces of a fight at the scene, and the man seemed to have committed suicide in fear of crime.

In Ms. Yun's bedroom, there is a well-preserved stroller, as well as children's clothes and shoes, and it seems that this woman has never been able to accept the fact that she has lost her child. The clothes and shoes are new, should have been bought freshly, never worn.

Pointing to an empty shoe box, the dragon said, "The shoes at the door should be in this box."

Bao Shu looked around the house, looked at the footprints on the snow outside the window and said: This is a murder, the murderer has disguised the scene.

Hualong said: If it wasn't suicide, could it be that the murderer was a child, and who left the small footprints on the snow in the yard?

Su Mei suddenly said: Ms. Yun's child, if she hadn't died, would she be six years old now, right?
