You're supposed to be a security officer, what case are you solving?

Chapter 339, Case Two!

Time flowed by in the office of the Third Brigade.

Yao Weihua shifted his hips, causing the chair to creak, pulling Yang Jinwen back to reality.

He looked up and saw that the table opposite him was already full of barbecue that had been brought back from outside.

Cai Ting and Maozi were sitting around the table, holding bamboo skewers and gnawing on chicken wings.

Yang Jinwen rubbed his sore eyes and asked, "Who bought it?"

Cat looked up at him and said, "Captain Yang, you're looking too intently. This is what Xiao Cai went out to buy."

Feng Xiaocai smiled and said, "It's late, I guess you must be hungry. The barbecue in Qincheng is pretty good. Team Leader Yao, Team Leader Yang, you should come and have some too."

Yao Weihua sat up and twisted his waist: "I'm just not born to sit in an office. My back hurts if I sit for too long."

If you're investigating a cold case, especially a long-standing one, you need to go through the case files in detail. The reports from forensic doctors and trace evidence specialists contain some professional knowledge that you need to understand clearly.

It would take a long time to read it all.

In particular, firsthand investigation reports contain many useful clues, and you never know which one might be the key clue.

Therefore, Yang Jinwen and his team reviewed the cases in parallel, memorizing the details.

Yang Jinwen stood up, stretched, and looked at the quartz clock on the wall. It was already past ten o'clock at night.

He walked to the table, dragged out a chair, sat down, and asked while eating, "Xiao Cai, you were involved in this case back then. How did you find out the identities of the victims in the 711 case?"

Feng Xiaocai picked up the thermos and stood beside them to pour water, saying, "I found it using my master's method. The victim, Zhou Lei, got her hair done at the hair salon downstairs where she lives. I remember it was about a week before the incident."

Yao Weihua asked, "Your master has a good eye for talent."

Feng Xiaocai smiled wryly, "He's too impatient. I think the reason he got into trouble, and the reason our original Third Brigade was disbanded, was because of the competition for the case-solving rate and the honor roll. If he hadn't been in such a hurry, my master and the original Third Brigade wouldn't have..."

Cai Ting tossed the bamboo skewer in her hand onto the table and asked, "What was Zhou Lei's cause of death? Where's the murder weapon?"

The cat said, "Didn't you see?"

"I haven't had time to read this part yet. I just read the investigation report, which said that the first crime scene was found because the victim Zhou Lei's pants were taken off, and then they found the place where she struggled and bled, right next to a twin tree."

Furthermore, Zhou Lei's money was taken, but the gold earrings were not taken by the murderer.

Then Zhou Lei was murdered by the killer, who ran away before she died.

Judging from the bloodstains, which formed a straight line, it means Zhou Lei immediately ran to the park guardhouse, about 50 meters away, to call for help.

Yang Jinwen nodded: "Therefore, Gao Jie concluded in his investigation report that Zhou Lei was familiar with the surrounding situation."

Feng Xiaocai replied, "Yes, it was later found that Zhou Lei was a silversmith. She went out to work as a prostitute that night, and we found many eyewitnesses."

But after 10 o'clock, there was no one downstairs in her apartment building.

The place where she solicited customers was only a little over 100 meters away from the grove of trees, separated by an alley and a street.

My master immediately deduced that the murderer had lured Zhou Lei to the woods, where the two of them not only assaulted her but also killed her.

As for the weapon used in the crime, forensic doctor Li determined it was a very sharp screwdriver. Zhou Lei was stabbed three times in the neck, piercing an artery.

From the moment she was stabbed to when she ran to the park guardhouse and cried for help, she died within a minute.

Yao Weihua took a sip of tea. He hadn't eaten any barbecue, seemingly not a fan of eating late at night. He asked, "So, how did the original Third Brigade investigate afterward?"

Feng Xiaocai put the thermos in the corner, then walked over and sat on an empty chair, putting her hands between her thighs.

"One approach is to investigate Zhou Lei's interpersonal relationships and conflicts of interest. Another approach is to find eyewitnesses and investigate some of Zhou Lei's old acquaintances."

At the time, the clues provided by the forensic and technical departments were that the murderer had left semen stains on the victim's thigh, which could serve as biological evidence, but this was a limited criterion and could not be used to screen for people.

Furthermore, the killer's footprints were extracted from the forest. The footprints indicated that the killer was between 170 and 175 centimeters tall and weighed between 65 and 70 kilograms, which is a fairly common range.

Based on these points, we investigated for half a month but found no clues.

Yang Jinwen asked, "Where are the fingerprints?"

No fingerprints were left.

Yao Weihua frowned: "Was the murderer wearing gloves when committing the crime?"

Feng Xiaocai shook her head, then nodded: "My master analyzed that if gloves were worn, they must be good quality, very smooth gloves, because the victim struggled and no fibers from work gloves were left on the victim or at the scene."

The case became unsolved after that. My mentor changed his thinking and concluded that the murderer must have been well-off, based on the crucial clue that no fingerprints were ever left behind.

"If an ordinary person committed the crime, especially stabbing the victim in the neck three times, their mental fortitude certainly wouldn't be that strong."

"How did the special task force formed by the First and Second Detachments conduct their investigation?"

“They didn’t investigate the 711 case. Captain Lu and Captain Shen believed that the 711 case was a random crime because, according to the victim’s roommate Wu Tong, they came out at 6 p.m. and at 9 p.m., Wu Tong received three customers while she was ‘working’ upstairs.”

Zhou Lei also had five guests that night, so the biological samples on her body were compared with those five people, and none of them were left by them.

In other words, between 6:00 and 10:30, according to this time period, Captain Lu and Captain Shen investigated everyone in the vicinity that night, but found no suspicious persons.

Therefore, they deduced that the murderer must have approached Zhou Lei around 10 o'clock, after the nearby shops closed.

In other words, the murderer either didn't scout the location on the night of the crime, or they scouted it beforehand, which is why they couldn't be found in the end.

Yang Jinwen stood up and picked up another case file from his desk, which was the murder case that occurred on June 9, 1997.

After he sat down, he opened the case file and said, "Xiao Cai, tell us about case 609."

Feng Xiaocai nodded, shook her long legs, and buried both hands between her thighs, looking somewhat uneasy.

"The victim's name was Wan Simiao, nineteen years old, and she was also a sex worker. Her murder was also very random..."

Random crimes are the most difficult to investigate; without a conflict of interest, it's impossible to uncover social relationships. Targeted physical evidence, such as biological samples and fingerprints, is also difficult to use due to limited resources to screen individuals. For example, is it possible to enter fingerprints into a computer database and immediately match them with a suspect? That's impossible nowadays.

"The incident occurred at 6 a.m. on June 9th at a garbage station on Sihai Road in Shilin District."

Behind the night market on Sihai Road is the old city area, which has many alleys called Sihai Hutong. The situation there is very complicated, with many small workshops hidden inside.

Before the incident, Wan Simiao was also soliciting customers in the alley. From 7 p.m. to 1 a.m., she and several other women sat on a bench inside No. 113 Sihai Road..."

Yang Jinwen found Wan Simiao's photo in the case file, as well as photos of the places where she "soliciting customers".

There are three concrete steps in front of the door, a roller shutter hanging above the door, and a transparent glass door below, which is open.

The reason it's a glass door is probably so that passersby can see what's inside.

Anyone with experience knows that if you go to a narrow alley where even Guan Yu wouldn't move, even if you have Red Hare, Green Dragon Crescent Blade, and are well-versed in the classics, you'll still have to take a few glances.

With just a few glances, you can tell who's behind the glass door: who's young, who's beautiful, who has fair skin, and who's curvy.

If you happen to meet a woman you like, or a woman who is similar to your crush, wouldn't you ask her price?
Even without asking the price, they couldn't resist the customers' offers.

"Hey, let's have a go."

You'll think to yourself, "Oh, from the southwest."

"Big brother, do you think I'm good?"

Oh, from Hedong.

"Just look...all you do is look, why don't you come in and stand here a couple of times and try it out?"

Oh, so this is where it is.

There's bound to be one that attracts you, whether you're from the north or the south.

Yang Jinwen passed the photos to Yao Weihua and the others, and they carefully examined the shop's facade.

Only Yao Weihua said regretfully, "It's a pity we didn't get any pictures of people."

The cat rolled its eyes.

Feng Xiaocai continued, "This entire building, five floors in total, is full of those kinds of businesses. There's a gang of thugs inside, and the leader is called Zeng Chao, nicknamed 'Grass Dog'."

Late at night on June 9th, Wan Simiao was sitting on a cool chair inside the door, with three other women with her.

Wan Simiao went out to buy late-night snacks around 11 p.m. and never came back.

After midnight, her body was discovered at a garbage dump in Sihai Hutong. The two men who were having a late-night snack at the night market called the police.

There was a toilet next to the garbage station. The door was locked at the time. People who had late-night snacks and drinks liked to urinate next to the toilet.

Two drunk men, while urinating, discovered a body in a garbage dump.

Yao Weihua asked, "How did they discover the body?"

At this moment, Yang Jinwen took out a stack of photos from the case file and showed them to them.

Feng Xiaocai recalled: "At that time, there was a stray dog ​​looking for food at the garbage station. It suddenly came out from inside, which startled the two people who reported the case."

They didn't pay attention and went back to drinking. The dog was running around in the night market when someone noticed that the dog's muzzle, neck, and leg hair were covered in blood.

The two men urinating were from the public security brigade and had some experience. They immediately found a flashlight and ran to the garbage station.

The garbage stations don't have doors; there are three large aluminum garbage bins placed next to the entrance.

They found Wan Simiao's body right behind the trash can.

The cat's heart skipped a beat: "That stray dog ​​licked human blood?"

Yang Jinwen found the photos from the scene and examined them carefully.

On the narrow road, police cars with flashing red and blue lights were parked. The entrance to the garbage station was cordoned off with rope as a warning line. Outside the line, a dense crowd of onlookers pointed and talked at the dark garbage station.

One of the photos, taken by a technician from the side, shows Gao Jie, the former captain of the Third Brigade, standing outside the rope, holding a flashlight and shining it into the garbage station.

Next to him were Gu Jun and Feng Xiaocai.

They saw a woman's head tilted to one side behind the dirty aluminum trash can.

Her face was turned outwards, her eyes wide open, facing the blinding beam of the flashlight.

Her neck and face were covered in blood and clumps of dog hair...

　I deleted my earlier heartfelt words; these things are a bit mysterious.

　　My uncle is 63 years old and is still working hard on the construction site to buy a house and get married for his third son in Chengdu. They have settled down elsewhere.

　　My second uncle left home at the age of thirteen to marry into a family in Qingchuan, which is quite far away. My maternal grandparents offered him no support whatsoever.

　　My youngest uncle, who is my mother's younger brother, suffered a heart attack six years ago and could not be saved.

　　That's the situation in my mother's family. After that, I stopped mentioning family matters.

　　It's so tough. I spent all day at the hospital yesterday, and when I woke up this morning, I found that I had sprained my left ankle. My right hand's tenosynovitis flared up, and I can't move the muscles on my thumb side at all. I also spent the whole day at the hospital today, limping and helping my mom get checked out. I wanted to rent a wheelchair, but I can't push it with my right hand.

　　I'll say it again: not a single lie is true, I swear to my ancestors! I don't even know how I managed to write these two chapters.

　　I won't mention these things again. People come to read books, not to hear me complain.

　　I set a timer, took my medicine, and went to sleep.

　　Take care of your health, everyone, especially now that winter is coming!
