The blind old man was surprised. This man was not a neighbor and he had never heard his voice before.
What a weird thing it is for a stranger to mop the floor in a strange corridor at night.
The old man was vaguely worried about the blind girl living next door, and he was on tenterhooks all night. How he hoped that the blind girl would show up safe and sound the next day.
Early the next morning, Bao Zhan and Hua Long led a team of police officers to arrive, and found a female body at the corner of the stairs - the blind girl had been killed.
The police immediately cordoned off and protected the scene, and the female forensic doctor quickly drove over. She was carrying a bag of steaming steamed dumplings in her left hand and a plastic bag in her right hand. There were several cartons of milk in the pocket. These breakfast items were bought from downstairs.
Bought from the roadside.
The female forensic doctor said: Everyone, please eat something. After eating, you can go to work. Your special case team won't be able to eat after seeing the corpse, right?
Hua Long picked up a small steamed bun, stuffed it into his mouth and asked: Will the inspection take a long time?
Bao Zhan said that he was not hungry. He pointed to the blood stains in the corridor and said: "I probably won't be able to complete the investigation work all morning. This murderer has cleaned up the murder scene."
The murder scene refers to the place and place where criminals commit murder, dismember bodies, hide, bury, and scatter corpses and body parts. Due to the different mentality, experience, motivation, purpose, means and environmental conditions of criminals, homicide scenes
It's quite complex, and each murder scene has its own characteristics.
Some murderers are calm and calm. Instead of fleeing the scene as quickly as possible after the murder, they clean up the murder scene and erase their own traces.
The characteristic of this murder case is that there is a lot of blood.
There are bloodstains both indoors and outdoors, and they are widely distributed. Bloodstains are both traces at the murder scene and physical evidence. They have very important criminal evidence value and identification function.
Bao Zhan had to take photos of every drop of blood to collect evidence, which was a huge workload.
The female forensic doctor measured the indoor and outdoor temperatures and the rectal temperature of the corpse. The blind woman was wearing autumn clothes and long trousers. 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. Female forensic doctor
After measuring the length of the wound caused by the single-edged knife, she said to Hua Long: This murderer is as strong and powerful as you. He swung the knife from right to left, and this woman's neck was almost broken.
Hua Long walked up and asked: What's the matter with the blood stains on the roof and the ground?
The female forensic doctor raised her head and said: Spray is formed. If a person is beheaded, the blood can spray as high as the second floor.
During the homicide scene investigation, the blood spatter analysis method can infer the state of the victim at the moment the blood spattered from the shape of the blood stains at the scene. If the blood is in the shape of a round drop, it indicates that the victim was in a still state at the time; if the blood has a "tail", it indicates
The victim is on the move.
Bao Zhan conducted a crime simulation and Hua Long visited his next-door neighbor. After the on-site inspection, Bao Zhan and Hua Long made detailed reports to Professor Liang.
The murderer was a man. There was no guardrail on the window of the deceased's room. The murderer used a glass knife to cut the glass and entered the deceased's room through the window. The murderer held a knife in his right hand and cut the throat of the blind woman in her sleep. The blind woman's blood spattered on the
There was a rain of blood on the roof, and the murderer cleaned up his bloody footprints in a shocking way.
Professor Liang asked: How to clean it?
Hualong said: Human mop!
Bao Zhan said: A clever and bold cleaning method.
The murderer hugged the legs of the female body, stood the body upside down, and slowly backed away, just like mopping the floor, using the deceased's hair to drag away the bloody footprints on the ground. He dragged it from the room to the corridor. In the corridor, the murderer met him by chance.
blind
The old man deceived him by claiming that he was "mopping the floor". He put the female body down at the corner of the stairs and fled the scene.
Professor Liang: The murderer was well prepared, bold and careful. Why didn’t he kill the blind old man?
Hua Long: The murderer might have seen that the old man was blind. In addition, the danger of committing murder in the corridor is relatively high.
Professor Liang: The blind woman was an eyewitness, and the murderer may not have known that she was also blind.
Bao Zhan: According to the interviews, the blind girl has only been working at this massage clinic for a few days.
Professor Liang: Those two words the murderer said - mopping the floor, were they in Mandarin or in the local dialect?
Hualong said: Mandarin.
Professor Liang: Immediately investigate the patients who have been to that clinic, focusing on people who speak Mandarin. The murderer should have gone to that clinic for massage before. He dragged the body and passed the old man in the corridor, but did not kill him.
The reason is because he knows that the old man is blind.
Not many local residents spoke Mandarin, so the scope of the investigation was greatly reduced, and a list was quickly made. There were only five Mandarin-speaking patients who had recently been to the blind clinic: a truck driver who often went for scraping and cupping, and a patient with lumbar disc herniation.
A lawyer, a migrant worker who sprained his foot and got bone-setting massage, a female accountant who had neck and shoulder massage, and a retired veteran cadre who went to a blind clinic to spend fake money and was caught out.
Blind people have particularly keen hearing and very good memory. According to the old man's recollection, he was very unfamiliar with the murderer's voice and seemed to have never come into contact with this person before.
Bao Zhan and Hua Long went to check the addresses one by one according to the addresses on the outpatient medical records. Some of the addresses were very vague. It was very difficult to find them and it took time to find them. Professor Liang required that the information of the patient's family members should also be obtained during the check, because
Patients are usually sent to the clinic by their family members, and the murderer may be one of them.
Professor Liang asked Su Mei to post notices in front of kindergartens, primary schools, infant clinics and children's playgrounds to find people with knowledge of the matter. Forensic examination proved that the deceased woman had a history of giving birth. If the deceased had children, she would definitely go to the above places.
, as long as someone knows or has seen the deceased, they can decipher the true identity of the unknown female corpse.
A few days later, a heavy snowfall came to the city. The special case team worked tirelessly and rushed around all day, and finally made a major breakthrough in the case.
A young woman once saw the deceased. She told the police a strange thing: 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 and a man with red hair wearing a white down jacket
The woman chatted casually for a few words, and when she accidentally glanced at her, her hair stood on end with fright. She saw the woman who was holding a child to share her parenting experience - there was a baby doll wrapped in her arms!
It was almost dark at that time, and the young woman was so frightened that she left immediately. When she returned home, she told her husband about the strange incident. A few days later, she saw a notice for the missing body in front of the clinic and immediately called the police.
Bao Zhan: Where do the dead go after dark?
Su Mei: It’s scary enough to wear white clothes and walk around the street at night, then add red hair and hold a fake doll in your arms. Oh my God, it’s scary just thinking about it.
Professor Liang: The deceased had a child, and it was probably because the child died that he was mentally disturbed.
Hua Long: If so, the deceased never believed that his child was dead and was living in fantasy.
Professor Liang asked the young woman to cooperate with the portrait expert to create a portrait of the deceased's face. Bao Zhan and Hua Long immediately visited the baby clinic to investigate. Unexpectedly, the clinic owner looked panicked when he saw the police, and he lied that he was not
The doctor, who was also a patient, secretly tried to escape under the pretext of going out to make a phone call. Hua Long subdued him and took him back to the city bureau for questioning.

Long: Why did you run when you saw the police?
Clinic owner: I’m afraid, I’ve been beaten before.
Bao Zhan: How many years has your clinic been open?
Clinic owner: Five or six years ago.
Hualong: Do you have a "Practice License for Medical Institutions"?
The clinic owner argued: My medical qualification certificate will be issued this year.
Bao Zhan: Did you see the body-finding notice posted in front of your clinic? Do you know the woman above?
Without saying a word, Professor Liang suddenly took out a few photos and put them in front of the clinic boss. When the boss saw the female body in the photos, he was so horrified that he almost fell off his chair. During the interrogation, key points should be highlighted to catch the suspect off guard and reduce the suspect's psychological defense.
Completely destroy it and let it honestly explain the problem.
This black clinic was opened by the owner and his wife, who had no medical qualifications, but because of its cheap prices and large number of patients, there were usually many people coming to see the doctor. It was banned once due to a doctor-patient dispute, and then quietly opened again. A few years ago
, a lady surnamed Yun brought her child to this clinic for treatment. After taking injections and taking medicine, she returned home and found that the child died unknown. Ms. Yun gathered nearly a hundred relatives and friends to the clinic to question the crime. They cried and made trouble, and moved the clinic like crazy.
It was smashed. Later, after mediation by the police station, the clinic owner paid a large sum of money in compensation, and Ms. Yun gave up. Unexpectedly, a few years later, Ms. Yun was mentally stimulated and came to this clinic again.
The clinic owner said: Oh, 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 Zhan: How many times has she been there holding a fake doll?
Clinic owner: I remember three times. Once she was dragged away by her husband, and another time she wandered around the hospital without entering the door.
Su Mei: Do you have children? Do you also treat your children?
Clinic owner: Yes, the boy is ten years old. This has been going on for several years and I have also lost money. Why do you think she is still here? Her child died at home. Who is our responsibility? Now, this woman is dead again.
, but it has nothing to do with us at all.
The identity of the unknown body was confirmed, and based on the address provided by the clinic owner, the special case team found Ms. Yun's home.
Ms. Yun runs a housing agency, and her husband is a surveyor from the Forestry Bureau. After their son died, the couple's relationship broke down. Neighbors confirmed that they often quarreled and divorced many times.
Ms. Yun's home is a small courtyard close to the street. The house rental information is written on the wall of a small house. The courtyard door is closed. There is a pair of children's shoes on the cement floor in front of the door. After Bao Zhan took photos and collected evidence, Hua Long planned to climb over the wall and enter.
When the door was opened, snow fell on the wall. Hualong stood on it, but he never jumped down.
Bao Zhan asked from below: What's wrong?
Hualong said: Bring the camera.
The snow has stopped, and there is a clear line of small shoe prints on the snow in the courtyard. The police found the body of Ms. Yun’s husband in the house. The forensic autopsy results showed that the man died of taking poison, and there were washed bloody clothes in the bathroom.
, and a chainsaw. The inspection results confirmed that Ms. Yun was murdered here. There were no signs of a fight at the scene. The man seemed to have committed suicide out of fear of crime.
In Ms. Yun's bedroom, there is a well-preserved stroller, as well as the child's clothes and shoes. It seems that this woman has never been able to accept the fact that she lost her child. The clothes and shoes are very new, they must have been bought newly, and they have never been worn.
Hualong pointed to an empty shoe box and said: The pair of shoes at the door should be placed in this box.
Bao Zhan looked around the house, looked at the footprints on the snow outside the window and said: This is murder, the murderer disguised the scene.
Hualong said: If it was not suicide, could the murderer be a child? Who left those small footprints on the snow in the courtyard?
Su Mei suddenly said: If Ms. Yun’s child had not died, would he be six years old now?
