After learning the information, the two returned to the police station. Gao Chongjiu went to his usual teahouse halfway and found an informant, asking him to keep an eye on the Han family.
"Why don't you take him back?"
"What if he doesn't explain everything clearly?" Gao Chongjiu said, "We are knocking the mountain. If he doesn't have something in his heart, he won't move. If he has something in his heart, he will definitely mess around in the past few days. Let's follow and watch.
That’s it.
"Master Jiu, you are really good at it." Li Ziyu presented him with a high hat and unconsciously brought out the old title.
"Hey, Ayu, I don't need you to be called Master Jiu." Gao Chongjiu was very humble, "I think even though we have a big age gap, we hit it off right away. It's a friendship that lasts forever. How many years am I older than you?
, how about you just call me 'brother'?"
"Okay, okay." Li Ziyu nodded repeatedly. This was much more intimate than calling him "Lao Gao".
Back at the station, a policeman sent a report. It turned out that the silver ingots confiscated by Gao Chongjiu from the money dealer had an appraisal report. Li Ziyu opened it and was surprised.
It turns out that the silver ingot with the stamp "Sanjiang Mao" written as the seized evidence was identified as the so-called "Zhu Ti Silver", which according to Australians is called "arsenic white copper".
"Not silver?!" Gao Chongjiu was also surprised.
"No." Li Ziyu handed him the report, "The victim's report records recorded five taels of silver ingots - which were obviously not taken away from him."
"What if his silver ingot is Zhu Ti's silver? By the way, it's called arsenic-nickel copper. It's exactly the same as silver. The only difference is the weight. If lead is poured into it, you won't be able to tell at all..."
"It's hard to say." Li Ziyu thought to himself, Chen Ding said it was silver, but no one had seen it. It was just talk. Who can prove that what he brought was silver, not this "arsenic-nickel copper"
Woolen cloth.
Now Chen Ding is in Lingao and cannot ask in person. Even if asked in person, he probably only knows that what he brought from home is "silver". As for whether it is "Zhu Ti Yin", not many people in Guangzhou know what's inside.
Chen Ding may not understand the difference.
Is this ingot of silver stolen from the flower-shooting robbery? Yes or no, it will affect the direction of the subsequent investigation. Neither of them dare to draw conclusions easily.
Li Ziyu's eyes suddenly lit up and he said, "What did Han Changle say? He stole it from a young man who was walking into the city from outside the city..."
Gao Chongjiu understood immediately: "Dashijie is in the city..."
In this case, the silver was probably not lost by Chen Ding. Otherwise, it would be difficult to explain why someone would deliberately send the silver stolen from the city outside the city and then send it back to the city again - isn't this a fool's errand?
"I just don't know if Han Changle is telling the truth."
"In my opinion, what he said should be true. Anyway, we have sent people to keep an eye on him, so we are not afraid of him getting into trouble."
"But this way, this case is still unsolved." Li Ziyu was very disappointed. He blinked his eyes, always feeling that he had overlooked something, but he couldn't remember it.
"Let's ask the money dealer!" After trying hard to "reason" for a long time, Li Ziyu thought, it is better to follow what the instructor said when he went to Lingao for training, when you encounter an unsolvable problem, you should read more and ask more questions.
There may be some clues that have been overlooked before.
Although money dealers are illegal, almost all money dealers in Guangzhou are under the control of the Criminal Police Department. The reason why they acquiesce in their existence is that firstly, they have little impact on the financial system and cannot cause much trouble; secondly, they are responsible for illegal activities.
It is an indispensable "channel" for people involved in illegal activities, equivalent to the police's ears and eyes at the lower level.
The money dealer's name is Yu San. During the Ming Dynasty, he specialized in selling various low-quality coins such as sand shells and wide films. He also bought and resold all kinds of trendy and rotten silver. After the new Australian currency was issued, he started a money exchange.
Black market business. Sliding silver dollar bills in and out of scattered silver, making huge profits.
Yu San knew that his business was illegal and it would take a minute for the Australians to deal with him, so he was always very cooperative with police investigations.
"Master Jiu, as I said yesterday, I exchanged this money from Han Changle. Although the withdrawal was a little harsh, the origin of his money was unknown - didn't all my money go in, and he still had it?
He refuses to pay me back..."
"You are not good at exchanging silver. You even exchanged Zhu Tiyin for it." Gao Chongjiu said with a smile, "If you want to sell it to others again, it would be strange if you don't get beaten to death..."
"Damn it!" Yu San's face changed. "This silver... is of good quality and heavy. I even cut it open and there is no lead core."
"It goes without saying what kind of silver it is." Gao Chongjiu waved his hand, "Let me ask you, do you find anything weird about this silver? Is there anything different about Han Changle from the past?"
"There's nothing weird, and there's nothing weird about Old Han either." Yu San blinked.
"Think again, there is something wrong with this matter, from the person to the money."
Yu San thought for a moment and said: "If there is anything special, it is the stamp of this silver. This is the first time I have seen it."
Yu San said that since he started this business, he has seen all kinds of stamps. Not only in Guangzhou, but also in large places in other places, he has seen almost all the brands of dumping houses. But this is the first time he sees this stamp.
.
"Because this is the first time we have met, I specially cut the silver pieces open..."
Li Ziyu suddenly shouted: "I remembered!"
This time, both Gao Chongjiu and Yu San were startled. Li Ziyu said excitedly: "I remembered! I remembered!"
He grabbed Gao Chongjiu and said, "Let's go back to the bureau!"
Although Gao Chongjiu was a little confused, he probably knew that he must have suddenly realized some new clues. He immediately said to San: "Don't run around these days. I can ask you anything at any time!"
"I have a family and business in Guangzhou, where can I go?" Yu Sandao said, "You two can come to me anytime if I need anything."
Li Ziyu returned to the station and immediately called a police officer to go to the archives room to retrieve the case file. After a while, a thick file was delivered to the office.
"Brother Jiu, look at this!" Li Ziyu handed the case file to Gao Chongjiu.
Gao Chongjiu took it and took a look. The label of the case file was labeled "Murder at Wang Xiuzhu's House in Nanjianzi Lane in 1635". Memories from the past suddenly flooded into his mind. Yes, the sensational "Guangzhou Witch Gu Case"
"It originated from here. The Li Ziyu in front of me also made his fortune from a series of "strange cases" in Nanjianzi Lane.
The murder case at Wang Xiuzhu's house was later handled together with the "Headless Case" as part of the witchcraft case. However, although the witchcraft case was solved, the real mastermind behind Wang Xiuzhu's death was not caught.
The murderer has not been found.
"this……"
"Look at the pages of physical evidence!" Li Ziyu said excitedly.
Gao Chongjiu turned it over and took a closer look, and immediately understood: "So that's it!"
"I was the one who went to the Jufeng to investigate the physical evidence. The silver ingots found from Widow Wang's house looked like this: Sanjiang Mao's stamp, Zhu Tiyin!"
"And this so-called copper arsenide or medicinal silver was later found in large quantities during the arrest of evildoers!" Gao Chongjiu muttered, "In this way, this matter is actually related to the remnants of the witchcraft case.
Relevant!”
"That's right. And shopkeeper Shen said that the stamp of Sanjiang Mao came from a dumping house in Foshan that was wiped out decades ago. It has not been circulated at all in the past few decades. Therefore, the silver stamped with Sanjiang Mao must be the same as this one.
Things are related."
"Then this Chen Ding who was robbed of money..."
"It is very possible that he is also involved in this matter - even if he is innocent, there must be some clues related to him. I will report it right away and arrest Chen Ding as soon as he comes back." Li Ziyu was very sure.
Gao Chongjiu really admired Brother Li now. Fortunately, he remembered this case from two years ago! Otherwise, he would still be confused!
Li Ziyu immediately went to report to Wu Xiang and suggested restarting the investigation of the witchcraft case.
"The investigation of the witchcraft case is now in charge of the Political Security Bureau. We are just assisting in the work." Wu Xiang thought for a moment and said, "I think you should not mention the witchcraft case for the time being, and focus on these first."
Investigate the ins and outs of the silver - who is casting these silver ingots and why they are transporting them into the city. I'm afraid things are not that simple..."
"Since the witchcraft case is not under our control, I suggest that it be investigated together with the counterfeit currency case." Li Ziyu continued the proposal, "These medicinal banks have deceived even private money dealers. If they enter the circulation field, they may confuse many civilians.
common people.”
Wu Xiang thought for a moment and said: "Just follow your idea and handle the case together. Your tasks remain the same. Report the clues you find directly to me. In addition, Chen Ding's matter is more complicated. You can't arrest him without my written order."
People can only ask in the name of helping solve the case, do you understand?"
"Yes, Comrade Section Chief!" Li Ziyu saluted excitedly. It seemed as if he saw that he had risen to another level in the ranking list of the Senate.
When he came out of the section chief's office, he realized that he had been happy too early. Although he had made a major breakthrough with the stamp of Shigeru Mijiang, there was still no specific breakthrough in the case. After discussing with Gao Chongjiu, he decided to divide it into several aspects.
.
The first is to notify private money dealers and local chambers of commerce to pay attention to whether there is any money stamped with "Sanjiang Mao". Once it appears, report it immediately, and at the same time try to find out the identity of the person exchanging and using it.
The second is to continue to track down the remnants of the flower-shooting case or the inflow of new "flower-shooting" criminals. Gao Chongjiu judged that since the witchcraft case, the local business has been almost wiped out, and most of the remaining ones have gone into hiding, so it is probably not
The actions of outsiders who understand the situation.
The third is to conduct a comprehensive investigation of the personnel of various dumping shops in Guangzhou City to determine the current whereabouts of these personnel.
