Several other netizens were also questioned by the police. One netizen, named "Duo De", showed a strong interest in the case and even wanted to get something out of the police. He asked the police if the murderer had 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 indicate that it is on the body parts of Diao Aiqing or on the package.
, there should be traces of gunpowder on the sheets, or Diao Aiqing had been shot with a shotgun. It is 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 the Drum Tower 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 911 corpse dismemberment case, the head of the deceased was boiled and was beyond recognition, making it difficult to identify. Six specially invited experts worked non-stop for a day and a half. They used phrenology recovery technology to restore the skull.
This is a very magical criminal investigation technology that can restore the original appearance of even the skull unearthed from the tomb. The photo shows that the deceased was a middle-aged man with thick eyebrows and big eyes, with a broad face and a hooked nose.
, wear 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 has 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 said with certainty at the beginning: 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 911 corpse dismemberment 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. The plastic bag had been thrown away
In the trash can, experts spent a lot of work. After first removing traces of other garbage stained by 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.
Trace experts said: We have made a comparison and found that the total protein content of milk is high, 3 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 say: 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 bags of clothes in the basket.
When driving past the trash can, she did not stop, just slowed down and glided, throwing the bag of body parts into the trash can. She probably wiped her lipstick accidentally and got the lipstick on her hands.
When I picked up the body bag, I left it on the plastic bag handle...
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 group 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. Traces
Experts used the Health Bureau's cooking oil rapid tester to test the aging degree of cooking oil, and put the metal probe of the instrument in contact with the oil. After 10 seconds, the reading displayed on the instrument was 42. This shows that cottonseed oil has been used many times, thus
There are signs of aging of the oil. Experts have 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: There is absolutely no mistake. 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: Please recall 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? It was a woman, wearing lipstick, riding an electric bicycle, with a black plastic bag in the basket.
The stall owner selling fried dough sticks thought for a while, shook his head, and suddenly said: If you ask this, is it related to the corpse dismemberment case?
Professor Liang didn't answer the question and said: Don't be afraid, just know something 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 reorganized the investigation direction. The murderer probably bought fried dough sticks and should live near the fried dough sticks stall. The investigation team focused 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 who sells 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 in the alley that have been converted from private houses. 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 enough time to 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 his disappearance, Diao Aiqing's case would have probably been solved. The student disappeared and the school
Knowing nothing, the school has an unshirkable responsibility.
Bao Zhan and two investigators stood in the alley, the wind blowing leisurely. 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 sycamore tree in the courtyard, and some broken glass is stuck on the wall to prevent criminals 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 also helps her husband with work.
Sewage flowed across the yard, garbage was everywhere, and there was no sewer in the alley. Most residents chose to dig a well in their 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 yard. 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 deceased in the 911 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, his eyes flashed.
A little panicked, he said that the police had shown this photo to him more than ten years ago.
Bao Zhan asked: What did you do in 1996?
The stall owner replied: Selling 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 when 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.
Very strange.
The stall owner immediately interrupted his daughter-in-law and told her to stop talking.
Bao Zhan asked her to continue, but the stall owner glared at his talkative daughter-in-law, turned 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?
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 dark, short, bald, with 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 50 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 facts of the case.
Bao Zhan asked: What has this hunchback in the crematorium committed?
