After deploying the next direction of investigation, I used a whiteboard marker to draw a big circle on the three words "little milk dog" on the clue carding board.

The pornography industry is illegal, and if there is no evidence, there is no investigation at all. You can't go door-to-door to ask, even if people have special services, they won't admit it.

If we don't get it right, we'll be taken for fools.

But this kind of thing, no department, knows better than the Public Security Section.

"Oops! Lao Qin! You know you're coming back to see us! ”

As soon as I walked into the Public Security Section, I heard a familiar voice, it was Captain Peng Yong.

"Captain Peng." I smiled and shook his hand.

"I don't dare to be the captain of this voice, you are now a star in the police world, and the heroic deeds of the serious crime team have long been spread." After Peng Yong finished speaking, he walked into the office of the Public Security Section with me.

In the office, I saw an acquaintance again, Shi Mingjie.

I will never forget this person, if it weren't for the lack of manpower he arranged at the back door, I would not have walked through the streets and alleys to hunt down the suspect, and I would not have met the stunned Qingli Dream at that time.

"Old Qin! You're back?! How? I made a mistake again and was transferred back? Shi Mingjie stood up and walked up to me to give me a hug.

"Shut up, you." I said with a smile.

"I haven't seen each other for almost a year, and I thought you had forgotten about us a long time ago!" Captain Peng Yong walked up to me and sat down, and said with a smile.

"I'm here this time for business." I settled down and said seriously.

Shi Mingjie glanced at me and said angrily: "I know that your kid won't come back if he has nothing to do, how can the public security department have a criminal police team attractive." ”

"Tell me Lao Qin, what do you need help from our Public Security Section?" Captain Peng Yong showed a serious expression, looked at me, and asked.

I took a deep breath and said in a deep voice, "Do you know where there are ducks in Ningzhou City?" ”

"Ducks? You're asking about ducks? Captain Peng Yong frowned suddenly, looking at us with some puzzlement.

He was a strange question, but I knew he was asking me if ducks were a profession or an animal.

"No, Lao Qin, I haven't seen you for half a year, do you still have this habit?" Shi Mingjie looked at him in disbelief.

"Don't make a fuss, I'm serious." I glared at him.

Shi Mingjie also said to me very firmly: "I didn't make trouble, I was serious." ”

"I came across a case, the identity of the murderer, most likely a duck." I said seriously.

Peng Yong, the captain of the "Duck ......", fell into deep thought, and after a while, he muttered: "This is the industry......"

"Yes, anti-pornography and anti-crime are your specialty, and the criminal police team has no clues." I shrugged helplessly.

"Lao Qin, I see that there is something wrong with your attitude. Anyway, you've been in the Public Security Section for three years, and even if you go back to your parents' house, you can't talk like that. Although it is the work of our Public Security Section to eliminate pornography and gangsters, that should not make us look like old bustards. Shi Mingjie said with a frown.

"It's all police, and it's all a family." I bumped him with my elbow.

"We don't really know about a industry like this. You have been in the Public Security Department for three years, and you should know very well that every time we get accurate information, or we have a report from the masses before we act. I don't know if you suddenly asked me that. Captain Peng Yong shook his head and said seriously.

"Of course I know this, that's why we came to you for help, after all, in terms of experience and ability, the security department is more professional." I said in a deep voice.

Peng Yong pursed his lips, pondered for a while, and helped me analyze: "This kind of industry has always been very stubborn, and it can't be cracked down at all, but if you want to talk about ducks, the scope is relatively small. After all, the duck industry is relatively special, the quantity is small, but the quality is high, and those in demand are generally powerful people. So if you want to find ducks, you have to go to high-end places to find them, and the scope of this place is very small, not all high-end places will have it. ”

I nodded, agreeing with Peng Yong's analysis.

"There's only so much I can do for you, and if I really don't know where it is. Even if you go door-to-door to ask, you can't ask about it, the most important thing in the fight against pornography and crime is intelligence. Peng Yong said lightly.

"High-end establishments ......," I muttered.

"You can fish for law enforcement." Shi Mingjie suddenly spoke.

Phishing law enforcement is a 'temptation to investigate and collect evidence', and although it is not a violation, it is not a good means to use. And from a certain point of view, it is strictly restricted by the authorities.

In legal theory, the parties did not have the intention to violate the law, and only engaged in illegal activities under the lure of law enforcement officers. Even if evidence is adduced in this way, it cannot be used in the chain of evidence, let alone as evidence for accusations.

"Although fishing law enforcement is a solution, I am afraid that there is no time. This is a homicide case, and even if some clues are investigated, there is no guarantee that it is related to the murderer in this case, which is too much of a waste of time. I took a deep breath and said in a deep voice.

Then he slowly stood up and said with a smile: "Thank you two brothers for your help, when this case is over, I will invite the brothers of the Public Security Section to dinner, and you can choose the place." ”

"Oh, the iron rooster Lao Qin is going to have a treat, it's not easy." Shi Mingjie also stood up and said with a smile.

"Okay, then we'll wait for Lao Qin's treat." Captain Peng Yong kept sending me out of the Public Security Division.

Although my trip to the Public Security Department did not investigate where there is an underground industry in Ningzhou City, I also have an important clue.

In the duck industry, the quantity is relatively small, and the quality is very high, and the customers are all powerful people.

Song Simeng is a powerful person, the quality of the ducks she can look at is definitely very high, not only in appearance and figure, but also in terms of education and thinking.

Moreover, after the murderer killed, the crime scene was also arranged, which shows that the murderer still has some artistic cells.

Perhaps, as long as we investigate what high-end places Song Simon has been in and out recently, including hotels, bathing centers, etc. Or the marketing department that Song Simon is currently in charge of, which high-end venue has recently cooperated.

In addition, Chen Yingying, who is a best friend, really doesn't know anything about these things?

"After investigating these, I will find an opportunity to meet Chen Yingying, let her rest at home for a day first, and when her mood is stable and her mind is calm, she will definitely tell us more clues." I muttered.
