When Fatty came to Ningzhou City, he must have engaged in drug trading, and he only had cash in his suitcase, without any drugs, which means that he had completed the transaction.

Since Fatty Rou came to Ningzhou City, two anti-narcotics policemen have followed and closely monitored him throughout the whole process, and Fatty Rou has not had time to connect and replace suitcases.

So, the luggage storage at the South Railway Station where Fatty Meat made a short stop must be a very crucial location.

The serious crime team immediately went to this luggage storage office to investigate the situation, this luggage storage office is in a corner of the exit of Ningzhou South Railway Station, the house is not large, and the words "supermarket" and "storage" are pasted on the glass windows.

It's not so much a supermarket as a commissary, which only sells some simple instant noodles, bread, mineral water and other emergency foods, and the type is single.

Behind the small shelves, there is a spacious open space where all kinds of luggage are stored.

It seems that the "supermarket" here is just a side hustle.

"Luggage storage? 15 small pieces, 30 medium pieces, 50 large pieces, here is the next note. ”

We had just pushed the door open and walked in, and a middle-aged lady sitting inside immediately uttered familiar words and handed over a thick register.

"Hello, from the Ningzhou Municipal Public Security Bureau? Are you the only one here? "I showed my police ID to the middle-aged eldest sister, and Li Meng and Lin Zifan around me were already looking for information about D selling fat meat in the thick register.

"Ah...... Yes, I'm the only one. She said with some panic.

The middle-aged eldest sister was stunned for a while after learning that we were police officers, she looked at us in a daze, and kept recalling in her mind whether she had done something illegal with her identity, but after thinking about it, she had been operating her duty and had never done anything illegal and undisciplined.

I saw her embarrassment, and then asked, "Have you seen this person?" ”

As I was questioning, I handed over a picture of the fat meat.

The middle-aged eldest sister took the photo and looked at it carefully, and finally said in a positive tone: "I've seen it!" ”

"Are you sure?" I frowned and asked her to confirm again.

"I'm sure, I've seen him! He came to me to store his luggage. The middle-aged eldest sister said without hesitation, and affirmed to me again and again.

"What luggage did he leave with you?" I looked at the middle-aged elder sister seriously and asked.

The middle-aged eldest sister looked at us and said very seriously: "This man is a monthly subscription here for me, and he will come to us around the tenth of every month to store a black lockbox, and at the same time take away an identical black lockbox. ”

"Black lockbox?" I looked at her, stunned for a moment, and then pulled a picture out of my pocket.

The photo shows a black lockbox, which Officer Wang found at the scene of the crime when he was investigating the traffic hit-and-run case.

According to Officer Wang, they found 560,000 brand-new 100-yuan bills inside the lockbox.

"Yes, yes, that's it! We have one more here! The middle-aged eldest sister nodded again in confirmation, and then took out the black lockbox at our request.

"It's exactly the same." Everyone came up and looked at it together.

The lockbox is a four-digit combination lock, and there is also a lock hole, which is a double combination lock. We don't have a professional tool to pick the lock now, so we can only wait a while to bring this lockbox back to the criminal police team and hand it over to the technical team for unlock inspection.

"Tell us more about it." I settled down and said lightly to the middle-aged eldest sister.

Subsequently, the middle-aged eldest sister told us about this fat meat in detail-

"This man comes every month, and he came on the 10th of this month, which was the other day. He's a regular customer here, and it's all on a monthly basis, and the price he gives is also very high, a little more than double the normal price.

Because it is my old customer, they are more familiar, so he does not need to register in the register, every time he comes to us after storage, I will give him a pick-up voucher, as long as you take this voucher to pick up the goods.

But the strange thing is that every time he comes to store his luggage here, within a few days a young woman comes and picks up his lockbox with a pick-up voucher and leaves an identical lockbox with me.

At first, I thought it was a little strange, but the pick-up voucher in the woman's hand was real, with accurate information and the man's signature, and I thought they might be a family.

What's more, the man gave me double the price, so I didn't ask why. ”

After listening to the words of the middle-aged eldest sister, we finally understood a little.

The D product transaction in Ningzhou City was completed in such a little-known and inconspicuous luggage storage office.

Fatty Meat carries a black lockbox containing D product and stores it here, and then a D seller in Ningzhou City will come here to pick up D product with the pickup voucher given to her by Fatty Meat, and at the same time put the cash to buy D product into an identical black lockbox and store it here, completing a stealing beam and changing pillars.

Then Fatty will find an opportunity, either this month, or the next month, to pick up the black lockbox containing cash that has been dropped and leave Ningzhou City.

And so on, once a month.

Thinking of the fact that the fat meat was wiped out, this case has nothing to do with our serious crime team, and it is very likely that the local D organization in Ningzhou City discovered that the fat meat had been discovered by the anti-narcotics police, and its identity was exposed.

Therefore, for the sake of their own safety, the local D-selling organization in Ningzhou City used a more extreme act of killing people and destroying mouths.

This shows that the deaths of Ruan Ningman and Ni Xueqing were also killed because of the exposure of the fat meat's identity.

This also further illustrates that the link connecting a certain D group on the southwest border through fat meat is Ningzhou City, a music bar that is harmless to people and animals on the surface.

Now, what we need to do is to find out who is the woman who made a black lockbox replacement with fat meat to complete the D product transaction?

Thinking of this, I took out my mobile phone and flipped out three photos of women for the middle-aged elder sister to help identify.

These three photos are Ruan Ningman, Ni Xueqing, and Cen Linghui.

The middle-aged eldest sister looked at the photos of the three of them and said directly to us: "It's her!" That's her! ”

"Are you sure?!" I stared closely into the eyes of the middle-aged eldest sister and confirmed to her in a serious voice.

Because the accusation of the middle-aged eldest sister plays a very key role in this case, this accusation can even directly change the direction of the case.

"That's right! That's her! She's been here for months, I can't be mistaken! The middle-aged eldest sister affirmed to us again.

The photo she was referring to was Ruan Ningman.

"She was really involved in the D-product trade." I froze and muttered.

Even if Ruan Ningman and Ni Xueqing's deaths were killed because of selling D, we must catch their murderers.

And this murderer and the mastermind behind the scenes must be the key person in the D-trafficking organization.
