The meeting room of the Second Brigade.

When Xie Qing arrived, Cao Haisheng and other criminal police had already taken their seats.

Huang Zhenyi presided over the meeting, and he summarized the situation investigated so far.

After a large number of visits, the criminal police received two feedback information.

A fishing enthusiast reported that around 18:00, a little boy and a man in a duckbill cap walked onto the embankment one after another.

But he was fishing at the time and did not pay attention to where the child ended up.

Moreover, the distance between them was more than 50 meters, and he could not see the appearance of the two clearly, and was not sure that the child was Huang Qi.

Another man who passed by on a bicycle reported that he saw a boy get into a red Xiali car during that time period, but he did not think that Xiali was a taxi. Because he did not think much about it, he did not pay attention to more details.

These two clues can only prove that a man in a duckbill cap may have taken Huang Qi away in a Xiali car.

They still know nothing about the murderer.

The three criminal police officers went to the Transportation Bureau and conducted a preliminary investigation of Xiali taxi drivers in the city.

There are quite a few young taxi drivers, with a total of more than 3,000 vehicles and more than 4,000 drivers working in shifts, and about half of them are under 30 years old.

As for whether the drivers are married and when they got married, it is difficult to find out in a short time because the data is not updated in time.

Therefore, if it is assumed that the murderer is a taxi driver, they can first conduct an investigation in Wangjiang Community and Qinghe area, which requires a lot of time and manpower.

After Huang Zhenyi finished explaining the situation, veteran detective Du Zhun raised a question: "It is reasonable to speculate that the murderer is a taxi driver, but we cannot rule out the possibility that he lives in the Qingjiang area and does short-distance transportation or has a private car at home. This range is not small. We still have to think of other ways to reduce the number of targets to be investigated as much as possible."

Huang Zhenyi said: "Old Du's point is very good. We need to narrow it down. Everyone, use your brains. Is there any better way besides investigating on foot?"

At this time, there was basically no surveillance. What good way could there be?

A dozen detectives, some smoking, some drinking tea, but no one spoke.

Huang Zhenyi sat down on the chair and saw Xie Qing as soon as he looked up. He wiped his unshaven square chin and asked with a smile: "Xiao Xie is smart, is there any way?"

The old detectives all looked at Xie Qing.

"Well." Cao Haisheng cleared his throat, "Xiao Xie is new here, and we haven't seen everyone yet, what can we do?"

He directly blocked for Xie Qing.

Huang Zhenyi laughed, "You, Old Cao, are already protecting your son."

Cao Haisheng said, "Tell the truth."

Huang Zhenyi didn't care, "Does Old Cao have any ideas?"

Cao Haisheng said, "The autopsy can only see so much, there's nothing we can do."

"You." Huang Zhenyi pointed at him with his index finger, then his face shrugged and he got back to the point, "The murderer has already killed three people and also attacked a child. The higher-ups are taking it very seriously, so we must hurry. Since there's no good way out, we can only investigate. Li Ji, go to the archives and look for old cases. Old Du, take your men to the traffic police brigade and check the owners of red Xiali cars in our city. Everyone else, go to the streets and do your best to check for Xiali taxi drivers who meet the requirements in the Qingjiang area."

...

After Huang Zhenyi made his arrangements, the criminal police officers in charge of the Huang Qi case dispersed.

Xie Qing and Cao Haisheng left the office building together.

Cao Haisheng said, "It's a good thing for young people to have opinions. The reason I stopped for a while is that I don't want you to show off too much. Let's wait and see."

Xie Qing said respectfully, "Thank you, Master. I understand."

Cao Haisheng nodded slightly, "You don't need a heavy hammer to sound the drum. I'm leaving first."

He went to the bicycle shed. .

Xie Qing also went to the dormitory. After walking a few steps, Li Ji chased out, "Xiao Xie, you are free anyway, so help me."

"Looking for files?" Xie Qing hesitated. They were all young people, and it would not be good for a man and a woman to be alone in a room.

"I'm coming! I'm coming!" Li Ke rushed over like a cannonball, carrying a big bag on his back. "I heard there's another murder?"

"Yes." Li Ji was happy. "Your father told you."

Li Ke's father worked in the procuratorate and was more informed than most people.

"Yes." Li Ke took Xie Qing's arm. "Let's go. I'll go with you to do anything."

The three of them talked as they walked, and soon they arrived at the archive room on the fourth floor.

The archive room is large and well ventilated, but even so, the air is filled with the moldy smell of old papers.

Li Ji took Xie Qing and Li Ke to a shelf at the back with ease. "

He moved out the two large boxes below. "These are unsolved cases in recent years. Let's look for them." "

Li Ke threw the bag on the shelf and squatted on the ground,"What are we looking for?"

Li Ji said, "Look for some similar cases, where a body was thrown into the Qingjiang River, or a head was split open with a brick."

Xie Qing took out several files from the box that Li Ji was holding and flipped through them quickly.

The three of them stopped talking, and the only sound in the quiet room was the rustling of papers.

About twenty minutes later, Li Ke said, "Look at this. "

Xie Qing and Li Ji gathered around - this was a vicious case that happened in an alley in the old city four years ago, where a victim was killed by a brick. The crime happened at night, the murderer ran away after the fight, and there were no witnesses. The victim was a gangster who often robbed minors. The case has not been solved yet.

Li Ji sat back, "This doesn't seem likely."

Li Ke asked Xie Qing, "What do you think?"

Without waiting for Xie Qing to answer, Li Ji explained, "This case is more like a vagrant crime. There are no clues, no witnesses, and except for the same tools used in the crime, there is no further connection. Even if it is really the same murderer as in the Huang Qi case, it can't help at all."

"That's true. "Li Ke put down the file convinced.

In fact, if it was the same murderer, the old city could be a possible investigation.

But what Li Ji said made sense.

Xie Qing nodded and concentrated on studying the file at hand.

...

The three of them squatted in the archive room for an hour and found nothing.

Li Ji locked the door, "I'm hungry, let's go eat."

Li Ke looked at the watch, "It's already this late, I guess there's nothing good to eat in the cafeteria, let's go eat some barbecue."

Li Ji said, "Barbecue is expensive, the cafeteria is free, just have a bite."

Xie Qing also wanted to eat barbecue, "I'll treat you, let's go."

"This..." Li Ji hesitated for a moment, "I have something else..."

Li Ke pushed him, "What can you do, we are colleagues, we are not dating, whoever has money can treat."

...

Fuyang Commercial Street is a famous barbecue street in Anhai City, among which Lao Wang BBQ is the most famous one.

The three of them found a small table and sat down.

Li Ke ordered thirty meat skewers and twenty tendons, Li Ji ordered a few vegetables and two steamed buns, and Xie Qing saw that the two were polite, so she had to help herself and ordered kidneys, oysters, lamb legs, and a few large shrimps.

Northeastern barbecue is very unique, the lamb is charred and juicy, and the chili is spicy.

The three of them are all good at eating, and the meat skewers and vegetables were gone as soon as they were served. It was not until the oysters and lamb legs were served that the speed slowed down, and there was also some left in the stainless steel plate.

Li Ji tore off a leg of lamb and put it on Li Ke's plate. "Eat what you need to make up for it. You will definitely have trouble tomorrow."

Li Ke asked, "So we'll just give up on the file?"

Li Ji said, "What else?"

Li Ke pursed his lips and said, "That's right."

Xie Qing tore off a leg of lamb and put it in her mouth. She said slowly, "I think we can go to the police station to have a look."

Li Ke said, "What about the four police stations? Do you want to check them all?"

Xie Qing said, "The Qingjiang River is the core area where the murderer committed the crime. The Qingjiang River runs through three districts, plus the Guta District, so there are four sub-bureaus. "

Li Ji said, "Okay, I'll talk to Captain Huang tomorrow morning and try to visit each sub-bureau." Li Ke

took the initiative to ask for permission, "You run two, I run two, we divide the work and cooperate, how about that?"

Li Ji said, "Why don't we go together, two people can find it faster than one person."

"That's fine." Li Ke agreed readily.

While the three were talking excitedly, a few young people came to the edge of Lao Wang's barbecue, including Chai Yu and Tan Yi.

Chai Yu picked up the beer cup and clinked it against Tan Yi's cup, "How about it, this barbecue is authentic."

Tan Yi took a sip, "Not bad, raw barbecue is much more fragrant than cooked barbecue.

Chai Yu said, "When you come, I'll have a companion."

Tan Yi picked up the cigarette box and tapped the bottom. A fragrant cigarette jumped out half an inch through the filter. He held it directly in his mouth and lit it with a lighter, "It's almost there, maybe another month."

Chai Yu leaned closer, "How about it, did you gain anything from this trip?"

Tan Yi frowned, "No."

Chai Yu said, "Anhai is not a big place, the economy is neither good nor bad, and most of the people live and work in peace and contentment, and are gentle and fearless. I don't think people will stay here."

Tan Yi took a puff of cigarette, "I think it's just the opposite..."

"What are you doing? "A crisp scolding interrupted Tan Yi's words.

Tan Yi stopped talking and looked towards the source of the sound...

About ten meters away, a sturdy man was scolding a girl who looked like a schoolgirl, "You little bitch, why are you yelling? If you do that again, I'll beat you to death."

The girl blushed, "How dare you scold me? You're a thief!"

"Who is the thief? What the hell did I steal? You're looking for death." The sturdy man raised his big hand like a palm-leaf fan, "I'm going to beat you to death!"

Tan Yi stood up, but was held down by Chai Yu, "Don't worry, there's someone... Hey, isn't that Xie Qing?"

"Xie Qing? "Tan Yi repeated suspiciously.

At this moment, a man and two women stood in front of the little girl.

Tan Yi then saw that Xie Chen's little sister was among them. The little girl was wearing sports shoes, jeans, and a black T-shirt, and her mouth was full of greasy food.

The strong man looked around and warned: "Boy, stop meddling in other people's business, or I'll beat you up too."

The girl with big eyes and round face sneered: "Look at you, you've forgotten the law."

"Law?! Damn, why didn't you say anything when that little bitch accused you? Do you think your brothers are easy to bully? "The strong man waved to a table in the east.

There were three people sitting at the small table. They were all sly-looking, strong and fat. They were not good people at first glance.

The little girl was not convinced, "I saw it clearly, you are..."

Xie Qing turned around and covered the little girl's mouth.
