◎Chapter 43: Dark Alley

Several other netizens also accepted the police's interrogation. One of them called "Many". He showed a strong interest in the case and even wanted to speak out from the police. He asked the police: "The murderer has a gun, right?"

Professor Liang and the Director of the Gulou Branch looked at each other, and the Director of the Gulou Branch said, "Why did you ask this?"

The netizen said that twelve years ago, when the police investigated the masses, they asked many times whether they noticed that there was gunpowder or hunting rifle in their home. This detail is very important, which may indicate that there should be traces of gunpowder on Diao Aiqing's body, or on the package, or on the bed sheet, or Diao Aiqing was shot by a hunting rifle. It is very likely that the crowd heard the sound of the hunting rifle on the night of the incident - otherwise, the police would not investigate gunpowder or hunting rifle!

The director of the Gulou said meaningfully: "Don't guess, there are some things that are the best. If you know today, you may die tomorrow."

Professor Liang said: "At that time, the Chinese New Year was approaching, and gunpowder was probably from firecrackers or fireworks. Don't guess it anymore."

After the dismemberment case, confirming the identity of the corpse was the focus of the investigation. In the "9/11" dismemberment case, the head of the deceased was cooked, and the face was beyond recognition and difficult to identify. Six specially invited experts worked non-stop for a day and a half. They used the skull recovery technology to restore the appearance of the head. This is a very magical criminal investigation science and technology, and even the skull unearthed from the tomb can restore its original appearance. The photos show that the deceased is a middle-aged man with thick eyebrows and big eyes, with a wide face, a hooked nose, and a pair of glasses.

All police officers in Lanjing City took action, each with a photo to investigate the identity of the deceased throughout the city.

The expert group made new progress and asked to hold a case press conference immediately. What kind of high-profile argument will they make? A trace inspection expert spoke on behalf of the expert group and said in a positive tone at the opening: "The murderer may be a woman!"

Before he finished speaking, a slight restlessness appeared in the venue, and many people began to whisper and whisper.

As long as you commit a crime, marks will be left.

In the "9/11" corpse dismemberment case, experts used a microscope to make meticulous searches on the black plastic bag containing the corpse. This was a brand new plastic bag that had not been used. Unfortunately, the fingerprint was not extracted. The plastic bag was once thrown into the trash can. The expert spent a lot of work. First, after eliminating other traces of garbage stains on the plastic bag, a small piece of stain was found 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 substance components inspections. There were red spots as small as pinholes in the stain. The experts initially thought it was a bloody mark. If it was a bloody mark of the murderer, it would undoubtedly be a major breakthrough in the case. The physical evidence inspection was extremely rigorous. The experts first used chemical experiments to detect whether the red spots were blood, and the result was very disappointed.

The red spots are not human blood!

However, the identification process was dark and the expert team found oil and milk from the stained ingredients, and the red spots were lipstick!

Trace experts said: "Lipstone can be inferred 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 expert said: "We have compared it and the total protein content of milk is three times that of human milk. The protein in milk is mainly casein, and human milk is mainly albumin."

Bao Zhan asked: "What kind of oil is oil, gasoline, diesel, or cooking oil?"

Experts said: "It's the oil we usually use to cook."

Bao Zhan said: "We can imagine passing by the body. In the early morning, before dawn, the street was pitch black. There was a woman wearing lipstick riding an electric bicycle without turning on the lights. She was in the basket with plastic bags and bags containing corpses, and drove past the trash bin.

When she was not stopping, she just slowed down and slid, throwing a bag of corpses into the trash can. The lipstick was probably because she accidentally wiped her lower lip and touched it on her hand. When she picked up the body bag, she left it on the plastic bag handle..."

Professor Liang said: "Is oil soybean oil, sesame oil, and rapeseed oil?"

The identification expert said: "This...we need further testing."

Professor Liang criticized the trace identification expert group, requiring them to understand the composition of the oil as soon as possible. After the meeting, the trace identification expert conducted an accelerated test and the results showed that it was cottonseed oil. This oil is rarely used in the home kitchen. The trace expert used the cooking oil rapid tester to test the aging degree of edible oil by the Health Bureau, and contacted the metal probe of the instrument with the oil. After ten seconds, the reading displayed on the instrument was 42. This shows that the cottonseed oil has been used many times, thus producing signs of oil aging. The identification expert also extracted: alkali and alum from the ingredients of the oil.

The appraisal expert hurriedly found Professor Liang and told him the good news.

The appraisal expert said excitedly: "Lao Liang, I 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's absolutely impossible to be wrong. This is the oil for frying fried dough sticks. Repeated use, alkali and alum, making fried dough sticks are essential."

Professor Liang asked Hualong to set off immediately and took the stall owner who fryed fried dough sticks near the scene of the throwing body back to the police station for interrogation. The stall owner was in his fifties and wearing an apron. He was an honest citizen. Every morning, he and his daughter-in-law set up a stall of fried dough sticks with his daughter-in-law. There were many customers, all of them around. He had no special impression of the customers who bought fried dough sticks on the day of the incident, and could not remember whether there were women wearing lipsticks.

Professor Liang said: "Remember it carefully."

Bao Zhan reminded: "On September 11, before dawn, were there any suspicious people among the customers who were eating breakfast and buying fried dough sticks? A woman, wearing lipstick, riding an electric bicycle, and holding a black plastic bag in the basket."

The stall owner who sold fried dough sticks thought for a while, shook his head, and suddenly said, "You ask, is it related to the corpse dismemberment case?"

Professor Liang answered the question irrelevantly and said, "Don't be afraid, just understand the situation. If you think of something, tell us."

After the stall owner selling fried dough sticks left the police station, Professor Liang re-established the investigation direction. The murderer was likely to have bought fried dough sticks and should live near the fried dough stick stall. The investigation and visiting team focused on the fried dough stick stall and conducted a basic investigation on a large scale. Even if nothing was found, at least the investigation circle could be narrowed and the focus was on single residents in the surrounding residential areas and people with criminal records.

For some reason, Bao Zhan became suspicious of the stall owner who sold fried dough sticks. The stall owner's eyes seemed to be vaguely concealed something, and there was a strange smell on his body. Bao Zhan took two investigators and went to the stall owner's house again.

The stall owner selling fried dough sticks lives in Xiaofen Alley.

This is a dilapidated alley, all of which are short and old old houses with peeling walls. There are many small restaurants for renovating private houses in the alley, and the sanitation environment is very bad. There are no street lights in this alley, and at night, the whole alley is very dark. Those low houses are covered with asbestos tiles, and locust trees and elm trees are growing in the yard. Occasionally a black cat walks by the wall. At night, passers-by walking alone in such a dark alley will feel chill.

It is hard to imagine that there is such a dilapidated alley in the bustling city. Coincidentally, this alley is near Lanjing University!

What is certain is that more than ten years ago, the deceased Diao Aiqing once walked through this dark alley.

More than ten years ago, there were bookstores and video disc shops in this alley. Diao Aiqing liked reading books. After the incident, the police investigated the bookstore and found no suspicious clues. Bao Zhan told the old director that it took nine days to get Diao Aiqing's disappearance to her body being discovered, and the murderer had time.

Clean up the murder scene. The old director agreed with this statement and regretfully stated that if the investigation started from the day of disappearance, the Diao Aiqing case may have been solved. The student was missing and the school knew nothing, and the school had an unshirkable responsibility.

Bao Zhan and two investigators stood in the alley, the wind blew quietly by, and when will the dead souls who had been wandering around for more than ten years rest in peace?

The stall owner who sells fried dough sticks lives in a courtyard in Xiaofen Alley, with several tiled houses. There is a sycamore tree in the yard, and some broken glass is inserted on the wall to prevent the villain from climbing. The stall owner's son is in his thirties and runs a mutton ramen restaurant. The ramen restaurant is a house facing the street of his home. His wife is very virtuous. When she comes back from selling fried dough sticks in the morning, she also has to help her husband with work.

The yard was filled with sewage, garbage was everywhere, and there were no sewers in the alley. Most residents chose to dig a dark well in their yard. Bao Zhan noticed blood near the sewer, and the two investigators became alert. The stall owner's son explained that he had killed sheep in the yard. Bao Zhan used his fingers to stain blood. He smelled it and nodded without saying a word.

Bao Zhan took out two photos - photos of Diao Aiqing and the deceased on the 9/11 corpse dismemberment case, and let them identify them. The stall owner's son and daughter-in-law had no impression of the photos. When the stall owner who sold fried dough sticks saw Diao Aiqing's photo, a hint of panic flashed in his eyes. He said that the police had also taken this photo for him to see more than ten years ago.

Bao Zhan asked: "What did you do in 1996?"

The stall owner replied: "I have sold fried dough sticks for more than ten years."

A detective joked: "You are an old man."

The stall owner didn't mind and replied with a smile: "You are really right, my nickname is Laowutou."

Bao Zhan asked again whether he was paying attention to any suspicious people when selling fried dough sticks in the early morning of September 11. His daughter-in-law thought for a while and blurted out: "Oh, oh, there is one, I have to tell you, this is very strange.

The stall owner immediately interrupted his daughter-in-law and scolded her not to talk too much.

Bao Zhan asked her to continue, and the stall owner glared at his talkative daughter-in-law fiercely and turned away. The daughter-in-law wanted to speak, but Bao Zhan encouraged her many times, and finally she said something hesitantly. That morning, before dawn, the daughter-in-law and her father-in-law set up a stall to sell fried dough sticks. A hunchback rides a donkey tricycle to buy fried dough sticks. There was a bulging black plastic bag on the tricycle. The daughter-in-law talks a lot and asks: "What is it inside?"

The camel replied: "Mermeat!"

After the hunchback left, the father-in-law scolded his daughter-in-law, and his daughter-in-law felt very wronged.

The father-in-law whispered to his daughter-in-law: "Do you know who the hunch is?"

The daughter-in-law said angrily: "How do I know?"

My father-in-law lowered his voice and said, "I know this person, the camel of the crematorium, he is the incinerator of the crematorium."

This incident is very strange. One morning, the camel who bought fried dough sticks, and the tricycle carries a pack of meat stuffing. He does not run a restaurant, nor sells buns or pies. He is a chemical in the crematorium. The stall owner who sells fried dough sticks did not tell the police about this out of timidity and caution, and Bao Zhan also expressed his understanding.

A investigator asked: "Is this hunch who is black and short, bald, has a big wrinkle in the corners of his eyes?"

The daughter-in-law said: "Yes."

The investigator gasped and asked immediately: "About fifty?"

The daughter-in-law replied: "Yes."

After coming out of the yard, the investigator looked around and whispered to Bao Zhan that the hunch had been dealt with by the police before, and his deeds had shocked the entire Lanjing police community. Out of considerations of social stability, the police have been concealing the case.

Bao Zhan asked, "What has this hunch in the crematorium committed?"
