The four members of the special case team felt that the case was serious. After getting off the plane, the main leaders of Lanjing Municipal Party Committee and Municipal Government were waiting for the arrival of the special case team. The pick-up team was luxurious and powerful. A secretary came forward to introduce Lan Jing to the special case team.
The Secretary of the Municipal Party Committee, the Mayor, the Director of the Lanjing Public Security Bureau, the Director of the Lanjing Public Security Bureau, the Secretary of the Political and Legal Committee, the Directors of the Lanjing Municipal Branch Bureaus... These leaders shook hands with the special case team one by one, and the expressions on each person's face and eyes
They all reveal expectations and trust.
It was already 11 o'clock at night when the special case team arrived at the Lanjing City Public Security Bureau. The office building was brightly lit, and there were many police officers lined up in front of the building to welcome them. The leader was an old man in his sixties, who was the boss of the Lanjing City Public Security Bureau.
Director, has retired. Twelve years ago, he served as the commander-in-chief of the "1.19" corpse dismemberment case task force.
The old director held Professor Liang's hand and said, "It's a shame. The '1.19' corpse dismemberment case was not solved, and now another corpse dismemberment case has occurred."
Professor Liang said: "Even big cases will always come to light one day. We will do our best. Now that criminal investigation technology is so advanced, there is great hope for solving the case."
The old director introduced the police who lined up to welcome them. These police officers had all participated in the investigation of the "1.19" corpse dismemberment case twelve years ago. They are now middle-aged and elderly, and many of them have gray hair on their heads. The old director took the initiative
He asked Ying to express to the special case team that they wanted to participate in the investigation work again. He said with mixed feelings: "It has been twelve years. I swore to the father of the child. I promised the people of the city that the murderer must be brought to justice."
Law, but now, after so many years, I still haven’t caught the murderer. Alas, how can I be worthy of the police uniform I wear..."
One of the police officers was filled with emotion and said: "It has been twelve years. The '1·19' dismemberment case was the first case I took over. It was my first day as a police officer. I also met Diao Aiqing's father.
, an honest farmer, for more than ten years, I often think of two little things, and I can't sleep well in my dreams."
The policeman talked about two small incidents when he visited Diao Aiqing's parents.
Diao Aiqing cannot ride a bicycle. She is a girl from a poor background. When she was a child, her father often took her on a bicycle. After the incident, her father said that when he was riding alone on a country road, he would always look back habitually.
Looking at the back seat, I realized that my daughter was gone.
After her daughter was murdered, Diao Aiqing's mother became taciturn. She worked in a diesel engine parts factory. Sometimes, when she was in a daze, she would think of a conversation she had with her daughter:
Diao Aiqing’s mother: “Aiqing, why is there a mole behind your ear?”
Diao Aiqing: "If you disappear in the future, you can find me."
Professor Liang decided on the spot that all the police officers who had participated in the investigation of the "1.19" corpse case would form a backlog team, which would be directly commanded by the special case team. The headquarters was set up in the office building of the Criminal Investigation Division 5 of the Lanjing City Public Security Bureau. The old director,
The three criminal investigation forces, the Director of the Fifth Criminal Investigation Division and the Director of the Gulou District, gathered together, and the three of them worked together with the Special Case Team.
That night, a major case headquarters involving public security departments at the central, provincial, and municipal levels was quickly established. The special case team served as the core leader and commander-in-chief. Insufficient police personnel were transferred from the entire province, and insufficient staff were transferred from various agencies. In short, everything needed to be done.
To ensure the progress of the investigation work, everything must provide convenience and help for major cases. The command headquarters consists of an investigation team, a forensic team, an on-site inspection team, and a physical evidence analysis team.
Computer technology team, trace identification team, archives management team, mass clue collection team.
The next morning, Bai Jingyu mobilized elite soldiers from across the country to form an expert team, which was urgently summoned to Lanjing City to join the major case headquarters. Among them were criminal portraits, DNA fragmentation identification, blood type analysis, dental science, and trace science.
, experts in criminal abnormal psychology and other fields, each of whom is well-known in the police circles across the country.
The major case headquarters is a gathering of heroes, with a super strong lineup!
The special case team held a meeting of 100 people to formulate general working principles and detailed task allocation. The "1·19" corpse case and the "9·11" corpse case, two cases of egregious nature, were jointly investigated and dusted.
The twelve-year-old unsolved case was opened again. The special case team entered the archives room. Professor Liang remembered the reason why Bai Jingyu did not take the case files - there were too many files and files on the "1.19" corpse dismemberment case, which filled several rooms.
Diao Aiqing's head had been boiled and had been frozen for more than ten years. A large number of photos show the scene when it was first discovered many years ago. The head had been boiled, so it showed a shocking red color. More than ten years ago, Lanjing police passed
The TV station extensively solicited clues and displayed two bags containing the corpse: one was a blue denim backpack and the other was an old-fashioned handbag. There was also a printed sheet containing the body fragments, hoping that citizens would provide clues.
Professor Liang sent several police officers to extract DNA and blood samples from Diao Aiqing's parents, and re-did DNA identification on more than 2,000 body parts and heads of the deceased Diao Aiqing. The bags and bedsheets used to package the body parts were tested for trace substances, in an effort to discover the remains of the murderer.
If the murderer's DNA can be extracted from the fine physical evidence that has been collected, the case will be solved soon.
A DNA identification expert said: Why did the murderer use red sheets? Alas, if they were white, we would find more clues.
DNA identification experts said that there was dark red dye on the sheets, which is a difficult inhibitor to deal with in DNA testing.
The method of committing the corpse dismemberment case twelve years later was very similar to the "1.19" corpse dismemberment case, and the location of the corpse was also very consistent. The special case team had a heated discussion at the meeting. Everyone had different opinions. Half of them believed that there were two cases.
The mutilation of corpses was committed by the same murderer, and the other half thought it was another murderer imitating the crime.
The three corpse dumping sites of the "9·11" corpse case were all closely protected by the police. Professor Liang asked Bao Zhan to lead the inspection team from the central site to fix the scattered objects, mark them, and then take pictures and extract them. Bao Zhan took the photo first.
They took down the whole scene and the central scene, and launched a search with a radius of two kilometers. However, no suspicious evidence was found in the periphery. The police transported the trash can where the body parts were discarded back to the headquarters, extracted all the objects inside, and used them for dozens of people.
After three days and three nights of detailed investigation, the police obtained no other useful information except the packaging bag containing the body parts.
The investigation and interview team extensively collected witnesses and initially believed that the murderer might have ridden the body on an electric bicycle. This is also strikingly similar to the "1.19" corpse dismemberment case twelve years ago - twelve years ago, the police believed that
The murderer was riding a bicycle to dump the body!
The major case headquarters established a laboratory.
For on-site inspection, physical evidence analysis, and trace identification, the three teams jointly established a laboratory equipped with the latest scientific and technological instruments, including scanning electron microscope, Fourier transform infrared spectrometer, microspectrophotometer, gas chromatograph/mass spectrometer, and gas chromatograph.
, liquid chromatograph, many
Band light source detection system, UV-visible spectrophotometer, thin layer scanner, forensic image analyzer, DNA amplifier, DNA sequencer, language recognition workstation, document inspection instrument, etc., and other laboratory equipment.
Professor Liang asked the identification experts to conduct the most meticulous inspection on the bags and plastic bags in which the body parts were packaged, trying to extract residual blood, semen, saliva, sputum, hair, nails, stains, oil stains, skin flakes or other human tissues.
The dead man's head was also boiled and his face was unrecognizable. DNA identified the dead man as male, about 40 years old.
There is a big difference between the two corpse dismemberment cases. The victim in the "1·19" corpse dismemberment case twelve years ago was a woman, 20 years old; the victim in the "9·11" corpse dismemberment case twelve years later was a male,
Forty years old.
The case became complicated. The special case team analyzed and discussed it. Bao Zhan made a bold assumption at the meeting. This 40-year-old middle-aged man might be the murderer of the "1.19" corpse dismemberment case. He was accused of the same crime.
Another possibility is that this person was an insider or witness who was killed and silenced by the murderer of the "1.19" corpse dismemberment case!
These two hypothetical questions make my hair stand on end!
The murderer killed the insider years later?
Did the insider kill the murderer years later?
Which one may be closer to the truth?
Su Mei used computer technology to find several netizens who posted on the Internet. Black Mass was interrogated by the police at the Gulou District Branch. He claimed that he had a legal background, had worked in courts and law firms, and now worked in a bank.
The online name is Black Mass. I named it because I like a heavy metal music album.
Professor Liang: "In 1996, you were only fourteen years old and still in junior high school. From this point of view, you can be ruled out as a suspect in the crime."
Director of Gulou District: "Why are you so concerned about the case more than ten years ago, and why do you think of posting on the Internet to speculate on the murderer?"
Black Mass said: "I became interested in this case in 2006 when I saw several posts about the case on the Internet. My original intention in posting was to attract private experts to come in and discuss the case together, but I didn't expect that some people would be suspicious.
I am a murderer."
Professor Liang: "I have read the reasoning and analysis in your post, and it makes sense. We will investigate in depth. You think the suspect is a male, and he was between thirty and forty years old at the time of the crime. There are also
They may be under thirty years old, have good appearance, mature and stable temperament, introvert, modest, single, highly educated, have high cultural quality, like listening to music, and may also be interested in literature, live near Lanzhou University, live alone, and know how to
Some medical knowledge, but no one knows it - but you ignored an extremely critical point."
Black Mass: "What?"
Professor Liang: "This is not a confidential issue. I hope you will shut up after understanding it."
Black Mass: "Okay, I'll shut up."
Professor Liang: "In the '1.19' corpse dismemberment case, all the internal organs and human bones of the deceased were not found. Where did these go?"
Black Mass: "Maybe it was thrown away by the murderer, or maybe it was buried."
Professor Liang: "There is another possibility. Think about the scariest place."
Black Mass: "Could it be that... my God, I was eaten by a murderer, and the murderer was a man-eating demon?"
