Several other netizens were also interrogated by the police. One netizen, named "Duo De", showed a strong interest in the case and even tried to get something out of the police. He asked the police: "The murderer has a gun."
,Yeah?"
Professor Liang and the Gulou Branch Director looked at each other, and the Gulou Branch Director said, "Why do you ask that?"
This netizen said that 12 years ago, when the police were interrogating people, they asked many times whether they noticed any gunpowder or shotguns in any house. This detail is very important, and it may mean that the body parts of Diao Aiqing, or the package
There should be traces of gunpowder on the bed sheets, or Diao Aiqing had been shot with a shotgun. It was likely that people heard the sound of the shotgun on the night of the crime - otherwise, the police would not have investigated the gunpowder or shotgun!
The director of Gulou said meaningfully: "Don't make blind guesses. It's best not to know some things. If you know today, you may be dead tomorrow."
Professor Liang said: "It was approaching the Chinese New Year, and the gunpowder was probably from firecrackers or fireworks. Don't make wild guesses anymore."
After the corpse dismemberment case occurred, confirming the identity of the corpse was the focus of the investigation. In the "9·11" corpse dismemberment case, the head of the deceased was boiled, making it unrecognizable and difficult to identify. Six specially invited experts worked non-stop for a day and a half.
Restoration technology restored the appearance of the skull. This is a very magical criminal investigation science technology. Even the skull unearthed from the tomb can restore its original appearance. The photo shows that the deceased was a middle-aged man with thick eyebrows and big eyes, with a broad face.
, has a hooked nose and wears a pair of glasses.
All police officers in Lanjing City took action, each taking a photo to identify the deceased throughout the city.
The expert group made new progress and requested to hold a briefing on the case immediately. What kind of speech will they make? A trace examination expert spoke on behalf of the expert group and began by saying with certainty: "The murderer may be a woman!
"
Before he finished speaking, there was a slight commotion in the venue, and many people began to whisper and whisper to each other.
Whenever a crime is committed, it leaves traces.
In the "9·11" corpse case, experts used a microscope to conduct a meticulous search on the black plastic bag containing the body parts. This was a brand-new, unused plastic bag. Unfortunately, no fingerprints were extracted from the plastic bag.
It had been thrown into the trash. Experts spent a lot of work. After first eliminating traces of other garbage on the plastic bag, they found a small stain on the handle of the plastic bag.
This stain is suspected to be left by the murderer.
The expert team divided the stain into 100 parts and conducted trace component tests respectively. There were red spots as small as pinholes in the stain. The experts initially thought they were blood stains. If they were the blood stains of the murderer, it would undoubtedly be a major breakthrough in the case. Physical evidence
The inspection was extremely rigorous. Experts first used chemical experiments to detect whether the red spots were blood, but the results were disappointing.
The red spots are not human blood!
However, during the identification process, the expert team discovered oil and milk from the ingredients of the stain, and the red spots were lipstick!
Trace experts said: "The lipstick can infer that the murderer may be a woman."
Su Mei asked: "Are you sure about the milk in the stain? Is it possible that it is human milk? This is very important."
The trace expert said: "We have made a comparison and found that the total protein content of milk is high, three times that of human milk. The protein of milk is mainly casein, while the protein of human milk is mainly albumin."
Bao Zhan asked: "What kind of oil is it? Gasoline, diesel, or cooking oil?"
Experts said: "It is the oil we usually use for cooking."
Bao Zhan said: "We can imagine that the body was dumped. In the early morning, before dawn, the street was dark. There was a woman wearing lipstick, riding an electric bicycle, without driving lights, and there were clothes in the basket.
Plastic bags and bags with body parts, driving past dumpsters
She did not stop the car, just slowed down and glided, throwing a bag of broken corpses into the trash can. The lipstick was probably smeared on her hands by accidentally wiping her lips, and was left in the plastic bag when she picked up the body bag.
On hand..."
Professor Liang said: "Is the oil soybean oil, sesame oil, or rapeseed oil?"
The identification expert said: "This... we still need further testing."
Professor Liang criticized the trace identification expert team and asked them to find out the composition of the oil as soon as possible. After the meeting, the trace identification experts did an expedited test and the results showed that it was cottonseed oil. This oil is rarely used in home kitchens.
Trace experts used a cooking oil rapid tester used by the Health Bureau to test the aging of edible oils. They put the metal probe of the instrument in contact with the oil. After ten seconds, the reading displayed on the instrument was 42. This shows that cottonseed oil has been used many times.
, resulting in signs of aging of the oil. The identification experts also extracted alkali and alum from the components of the oil.
The appraisal expert hurriedly found Professor Liang and told him the good news.
The appraisal expert said excitedly: "Lao Liang, we figured it out, this is a kind of oil used to fry fried dough sticks!"
Professor Liang asked in surprise: "Are you sure?"
The identification expert said: "It is absolutely unmistakable. This is the oil used for frying fried dough sticks. It is used repeatedly. Alkali and alum are essential for making fried dough sticks."
Professor Liang asked Hua Long to set out immediately and bring the fried dough stick stall owner near the body dump site to the police station for questioning. The stall owner was in his fifties, wearing an apron, and was an honest citizen. He and his son would go there at 4 a.m. every day.
His wife ran a fried dough stick stall together, and there were many customers, all of whom were nearby residents. He had no special impression of the customers who bought fried dough sticks on the day of the incident, and could not recall whether there was a woman wearing lipstick among them.
Professor Liang said: "Remember it carefully."
Bao Zhan reminded: "On September 11, when it was still dark, was there anyone suspicious among the customers who were eating breakfast and buying fried dough sticks? A woman was wearing lipstick and riding an electric bicycle. There was a black plastic bag in the basket.
.”
The stall owner selling fried dough sticks thought for a while, shook his head, and suddenly said: "You are asking this, is it related to the corpse dismemberment case?"
Professor Liang didn't answer the question and said, "Don't be afraid. I just want to know a little bit about the situation. If you think of anything, just tell us."
After the stall owner selling fried dough sticks left the police station, Professor Liang re-established the direction of the investigation. The murderer probably bought fried dough sticks and should live near the fried dough sticks stall. The investigation and interview team centered on the fried dough sticks stall and conducted a basic investigation in a larger area.
, even if nothing is found, at least the investigation circle can be narrowed, focusing on single households in surrounding residential areas and people with criminal records.
For some reason, Bao Zhan became suspicious of the stall owner selling fried dough sticks. The stall owner's eyes seemed to be hiding something, and there was a strange smell on his body. Bao Zhan took two investigators and went again.
The stall owner's home.
The stall owner selling fried dough sticks lives in Xiaofen Alley.
This is a dilapidated alley. They are all short and old old houses with peeling walls. There are many small restaurants that have been converted from private houses in the alley. The sanitary environment is very poor. There are no street lights in this alley. At night, the whole alley is very dark.
It is dark. Those low houses are covered with asbestos tiles, and there are locust and elm trees growing in the yard. Occasionally, a black cat walks on the wall. At night, passers-by walking alone in such dark alleys will feel chilly.
It is hard to imagine that there is such a dilapidated alley in a bustling city. Coincidentally, this alley is near Lam Kyung University!
What is certain is that the deceased Diao Aiqing walked through this dark alley more than ten years ago.
More than ten years ago, there were rental bookstores and video stores in this alley. Diao Aiqing liked reading. After the incident, the police investigated the bookstore and found no suspicious clues. Bao Zhan told the old director that from the time Diao Aiqing disappeared to the time he was found,
It took nine days to dismember her body. The murderer had all the time
Clean up the murder scene. The old director agreed with this statement and regretfully said that if the investigation had started from the day of the disappearance, Diao Aiqing's case would probably have been solved. The student disappeared and the school knew nothing about it. The school has an unshirkable responsibility.
.
Bao Zhan and two investigators stood in the alley, with the wind blowing quietly. When will the souls of the dead who have been wandering for more than ten years rest in peace?
The stall owner selling fried dough sticks lives in a courtyard in Xiaofen Alley, with several tile-roofed houses. There is a plane tree in the courtyard, and some broken glass is stuck on the wall to prevent bad guys from climbing on it. The stall owner's son is in his thirties and runs the business.
I own a mutton ramen restaurant. The ramen restaurant is a house facing the street from my house. My daughter-in-law is very virtuous. When she comes back from selling fried dough sticks in the morning, she has to help her husband with work.
Sewage flowed across the yard, garbage was everywhere, and there were no sewers in the alleys. Most residents chose to dig a well in their own yard. Bao Zhan noticed blood stains near the drain, and the two investigators became vigilant. The stall owner's son explained that he was
A sheep had been killed in the courtyard. Bao Zhan dipped his fingers into the blood, smelled it, and nodded without saying a word.
Bao Zhan took out two photos - photos of Diao Aiqing and the victims of the "9·11" corpse dismemberment case, and asked them to identify them. The stall owner's son and daughter-in-law had no impression of the photos. When the stall owner selling fried dough sticks saw Diao Aiqing's photo, he
With a flash of panic in his eyes, he said that the police had shown him this photo more than ten years ago.
Bao Zhan asked: "What did you do in 1996?"
The stall owner replied: "I sell fried dough sticks. I have been selling fried dough sticks for more than ten years."
One of the investigators joked: "You are an old fool."
The stall owner didn't mind and replied with a smile: "You are right, my nickname is Laoyoutiao."
Bao Zhan asked again whether he noticed any suspicious people while selling fried dough sticks at the stall in the early morning of September 11th. The daughter-in-law thought for a while and blurted out: "Oh, oh, there is one, I have to tell you about this."
Things are very strange.
The stall owner immediately interrupted his daughter-in-law and scolded her to stop talking.
Bao Zhan asked her to continue, but the stall owner glared at his talkative daughter-in-law, turned around and left. The daughter-in-law hesitated to speak, Bao Zhan encouraged her many times, and finally she hesitated to talk about one thing. That morning,
Before dawn, my daughter-in-law and her father-in-law went out to sell fried dough sticks. A hunchback came to buy fried dough sticks on a donkey-riding tricycle. There was a bulging black plastic bag on the tricycle. The daughter-in-law was talkative and asked: "What's inside?"
What are you pretending to be?"
The hunchback replied: "Meat stuffing!"
After the hunchback left, the father-in-law scolded his daughter-in-law, who felt very wronged.
The father-in-law whispered to his daughter-in-law: "Do you know who that hunchback is?"
The daughter-in-law said angrily: "How do I know?"
The father-in-law lowered his voice and said, "I know this man, the hunchback at the crematorium. He is an incinerator at the crematorium."
This thing is very strange. One morning, the hunchback who bought fried dough sticks carried a bag of minced meat on his tricycle. He did not run a restaurant, nor did he sell steamed buns or pies. He was an incinerator at the crematorium. The stall owner sold fried dough sticks.
Out of timidity and caution, he did not tell the police about the matter, and Bao Zhan also expressed his understanding.
An investigator asked: "Is this hunchback black and short, with a bald head, triangular eyes, and a big mole at the corner of his eye?"
The daughter-in-law said: "Yes."
The investigator took a breath and immediately asked: "Around fifty years old?"
The daughter-in-law replied: "Yes."
After coming out of the yard, the investigator looked around and told Bao Zhan in a low voice that this hunchback had been dealt with by the police before. His deeds had shocked the entire Lanjing police community. Out of concern for social stability,
Considering that the police have been concealing the case.
Bao Zhan asked: "What has this hunchback in the crematorium committed?"
