I handed the commemorative coin to Li Meng and stopped in front of the scavengers.

The scavengers seemed to have gone mad and kept coming forward to rob them.

"I'm a police officer from the Ningzhou City Public Security Bureau, do you know that this is an attack on the police?"

Every time a scavenger stepped forward, I took a step back and kept a safe distance from him.

Although the scavenger is crazy, he is not completely unable to communicate, he still has a clear mind and reason.

"Can the police rob something?" The scavengers questioned me in turn.

I looked at him and asked the question again: "Where did you get this gold coin?!" ”

"I picked it up!" The scavenger shouted.

"Picked up? Where did you pick it up? It's clearly stealing! Li Meng, who was beside him, looked at the scavenger and sneered.

"I ...... I didn't steal! God gave it to me! The scavenger suddenly said something inexplicable.

"God gave it to you? Why didn't God give it to me? Li Meng showed a very disdainful look.

The scavenger was a little short of words for a while, and he didn't know what to say, so he hesitated for a long time, and said to us angrily: "It was given to me by God, I was sleeping that day, and this thing fell from the sky and fell beside me!" ”

After listening to him, I suddenly frowned and looked at the scavenger seriously: "You said this thing fell from the sky?" You elaborate. ”

"In the early hours of the morning the day before yesterday, I was sleeping when this thing fell off. There's no one around me at all, this thing just fell from the sky! The scavenger said in a deep voice, very sincerely.

"Early the morning before yesterday?" Li Meng was suddenly stunned and said to me, "Isn't that the time when He Chunhua was killed?" ”

"Could it be that this gold coin was stolen by the murderer after the murder? And then when the murderer climbed the stairs, he fell right in front of the scavengers? I looked at Li Meng and muttered.

"It's possible, but it's too coincidental......" Li Meng looked at the gold coin in his hand and said with some incredulity.

"The case itself is made up of countless coincidences. After all coincidences are ruled out, the last thing that remains is incredible, and it is also the truth of the facts. I took a deep breath and said lightly.

Li Meng nodded, and suddenly asked me, "What about this coin?" ”

"This is evidence, bring it back to the bureau, see the source of this gold coin, if it is not He Chunhua's, or it has nothing to do with this case, just return it to him, maybe this is really a gift from God." I looked at the scavenger in front of me and said in a deep voice.

After explaining the situation to the waste pickers, we immediately returned to the Ningzhou Municipal Public Security Bureau to investigate the limited edition Olympic commemorative coin sold by the bank.

Only 20 million sets of this commemorative coin have been issued nationwide, which is less than any other commemorative coin.

It was sold out in an instant after the release, and then the bank issued a new edition of the commemorative coin, a total of 200 million sets.

But the two sets are not the same, and the one in my hand, which is obviously the first set to be issued, has a very high collector's value, and it is not something that can be bought with money.

Each set of commemorative coins has a unique serial number and is purchased under a real-name system, which can be traced back to the identity of the buyer.

"The buyer of this set of commemorative coins is the owner of a liquor company, and we have contacted the owner, who said that he gave this set of commemorative coins to the company's largest shareholder, Murong Jin, three years ago. Then, I contacted Murong Jin again, and he said that he gave it to He Chunhua after changing hands. Lin Zifan said seriously.

"This set of commemorative coins is really He Chunhua's, and it is very likely that the murderer fell when he returned to the rooftop through the fire hose after the theft and murder." I said in a deep voice.

"In other words, the remaining two commemorative coins are now with the murderer!" Li Meng immediately said in a loud voice.

I paced around the office of the Crime Squad and pondered for a moment: "The murderer must have gone for money when he burglarized and killed someone, so he will definitely not collect the two commemorative coins in his hand, but will find a way to exchange them for cash." ”

I muttered a few words, raised my head, and said to Lin Zifan, "The murderer will definitely find a way to sell these two silver coins and copper coins, but if the most valuable gold coins are missing, the collection value will also decrease." ”

"Therefore, the murderer will definitely go to the place where the gold and silver jewelry is recovered and sell the silver coins." Li Meng said immediately.

I nodded, and hurriedly said to Lin Zifan: "Contact Xue Hang, and you will investigate all the banks in Ningzhou City and the places where gold and silver jewelry are recovered." If you see this coin, report it to the police immediately and don't alarm the suspect. ”

"Okay, I'll do it!" After Lin Zifan answered, he turned around and went to do it.

After a while, Jiang Tingbai, who had not been seen for a long time, walked into the office of the serious crime team.

Actually, I haven't seen him for a long time, and I haven't seen him for two days.

"Lao Qin, I have carried out a detailed trace inspection of this gold coin. The gold coin has had serious impact marks, and there have been traces of metal extension to varying degrees, which is very consistent with the deformation of the metal falling high. Jiang Tingbai handed me a trace examination report.

If I can read the autopsy report, I can only read half of it.

All above are the detection and inference of metal ductility, various graphs and formulas, and some technical terms.

"It's pretty professional." I looked at it and said casually.

"Low profile! Low-key and low-key! Jiang Tingbai said proudly.

"Now that we've cast our nets, we're waiting for the fish to come in." I took a deep breath and said lightly.

I stood up and walked slowly to the window, looking outside.

It's the height of summer, and there is peace between heaven and earth, and there is green everywhere.

The sun was so dazzling that everyone was trying to find a way to hide from the scorching sun.

Who can hide from the sun?

A few hours later, news came from a bank in Ningzhou City that a woman had approached the staff at the window with a limited edition of silver and copper coins and wanted to exchange two commemorative coins for cash equivalents.

"What about the people who came to exchange the commemorative coins?" I hurriedly asked.

A staff member walked up to me and said to me, "When she came, she looked very anxious and asked me to exchange cash." I immediately reported the situation to the foreman manager and stabilized her. But she seemed to be in a hurry, and she didn't wait long, and left. ”

"Call up the surveillance, I'll see." I settled down and said seriously.

"Okay, please come with me." The staff smiled and led me to a nearby office.

The surveillance footage has been retrieved, and the picture shows a woman holding two commemorative coins in her hand.
