"Switched? How is that possible! My father seldom goes out, let alone comes into contact with the captain and Dong Ge. How could he have the time to switch coins? Besides, the copper coins in our hands are very special. Even if they were switched, we can easily identify them!" Xiaopang refused to believe what I said from beginning to end, and the team leader said even more disdainfully: "Do you think we didn't think of it? After the forensic doctor took out the copper coins, we also found an antique appraisal expert to appraise them. The copper coins in the mouths of the two deceased were authentic ancient copper coins. This family is so poor, how could they have the money to buy other copper coins to switch them?"
My words did sound a bit ambiguous. In fact, what I said was not what they understood at all, so I said, "I didn't say that these three copper coins were fake. What I said was that Xiaopang's father, the murderer of this case, just switched the positions of the copper coins in your hands. It was by taking advantage of this that this case looks so weird!"
When Dong Ge died, I not only concluded that the murderer must have changed his clothes in a hurry after killing someone and escaping, but also that the murderer knew where the copper coins in Dong Ge's house were hidden, because Dong Ge's room was not messed up, so how could he find the copper coins in Dong Ge's house in such a short time? It was because of this that I initially locked the suspect on the captain who behaved strangely and looked for Dong Ge in the afternoon.
In fact, I was wrong at that time. The murderer was very smart. He did not spend time to find Dong Ge's copper coin and put it into Dong Ge's mouth. Instead, he directly put the copper coin on Xiao Pang's body into Dong Ge's mouth! Because the scene we saw at that time was that Dong Ge died with the copper coin in his mouth, and the three parties who had the copper coin were present at the time, and the so-called curse a few days ago made the atmosphere so weird, which made everyone think that the copper coin in Dong Ge's mouth was his own.
After Dong Ge's death, his family members were grieving in the police station almost every day, so there was a lot of time when no one was at home. The murderer only needed to choose a time when no one was at home and sneak into Dong Ge's bedroom to find the copper coins that truly belonged to Dong Ge. It was for this reason that when Lin Yingxue and I went to Dong Ge's house just now, we saw that the originally tidy bedroom had been turned into a mess.
Since the first victim, Dong Ge, was deceived by the murderer in this way, then the second victim, the captain, is easy to explain. The murderer sneaked into the captain's house and killed the captain while we were burying the copper coins. Then he put the copper coins he found in Dong Ge's house into the captain's mouth, found a place to hide it and waited quietly. After all of us came back, he went to the place where we buried the copper coins and dug out the last copper coin, and used this copper coin for himself.
After listening to my explanation, Lin Yingxue beside me had a look of sudden enlightenment on her face. Obviously, even she understood it, and I believe that most of the people present should have understood it as well.
The team leader was still unconvinced and gritted his teeth and said, "All this is just your speculation. Do you have any evidence to prove that the murderer secretly used this method to swap the order of the three copper coins?"
Facing the captain's repeated provocations, I also felt a little angry in my heart. I turned my head and stared at him coldly and said, "Let's recall that when the captain died, we buried the captain's copper coins, and we buried them directly without wrapping them with anything. So, after digging out the copper coins, they should be more or less stained with dirt, right? But look at these two copper coins in my hand. The blood-stained copper coin is the one found in the captain's mouth. The copper coins are basically spotless except for rust. Obviously, these are not freshly dug copper coins at all!"
After that, I turned to the medical examiner and said, "Did you check the condition of the copper coin in the deceased's mouth when you examined him just now?"
The forensic doctor nodded and said, "Of course I have seen this. The saliva in the deceased's mouth has dried up, but there are still some traces of mud left where the copper coin touches the tongue. I think your analysis is completely correct."
After hearing the forensic doctor's affirmation, I think everyone present should have understood. The team leader glared at the forensic doctor fiercely, as if he wanted to say that the forensic doctor was a traitor, but the forensic doctor ignored him at all. It can be seen that this team leader is not well-liked even in the local police station.
"To sum up, the copper coins that appear in our hands now are the copper coins that Brother Dong said belonged to Xiaopang, the copper coins that the captain said belonged to Brother Dong, and the copper coins that the murderer said belonged to the captain's family. All three copper coins have passed through the hands of the murderer. Although the murderer was cunning and did not leave fingerprints on the body, there should be fingerprints of the murderer on it, right? If the fingerprints of the murderer, who should not appear, appear on all three copper coins at the same time, can we completely lock in the suspect of the murderer? There is also the trace of mud left on the edge of the copper coin in the murderer's mouth. If it doesn't work, you can compare the mud with the mud in the area where the copper coins were buried at that time. I believe there will be a result soon."
When I said this, Xiaopang and his mother were shocked, and the team leader knew that the matter was a done deal, so he asked, "But why did he do this? First he killed two people with a curse, and then he committed suicide. What exactly did he want?"
"Good question! I couldn't figure this out before, but I just got a hint from someone and made a bold guess. Then I finally understood why he did all this. He did it all for profit!"
My dad said that fame, wealth and love are the three things that everyone does. This reminded me of the motive of the murderer in this case. So I was wondering, what is it that Xiaopang's father can get after his death? After thinking about it, I only have one answer, that is, the insurance money!
Although I know nothing about insurance, I have watched some TV programs which said that people who commit suicide will not receive insurance compensation. That's why Xiaopang's father painstakingly designed a series of murders, and eventually made his own suicide look like a murder. In this way, he could get an insurance money and leave it to his son and wife.
Before, I always felt that the date marked on the calendar was definitely an important clue. After my reasoning, I could instantly bring in the date clue on the calendar. I called Bai Qi to help me investigate whether Xiaopang’s father had bought any insurance. Sure enough, Bai Qi’s answer was that Xiaopang’s father bought accidental injury insurance with a considerable amount of money about two years ago, which was the eve of his complete bankruptcy, and the beneficiary was Xiaopang’s name. However, this insurance will not take effect until two years later, and the day he bought the insurance was the day marked on the calendar. In other words, two years ago, Xiaopang’s father had actually planned everything. Although I don’t know if he had decided to kill people at that time, he had not gone out to work in the past two years and chose to die today. His purpose was to get this insurance money and let his son and wife get rid of poverty and live a good life.
When I got to this point, I couldn't go on. After all, if I exposed this matter today, the insurance company would definitely not give Xiaopang the insurance money he deserved according to the contract, and the death of Xiaopang's father would become meaningless.
But if I didn't say anything and let Xiaopang's father's conspiracy succeed, I would feel that I was a little sorry for the captain and Dong Ge who died innocently because of this matter.
After hearing everything I said, the team leader immediately picked up the phone to confirm the matter. Ten minutes later, the team leader looked at me with a complicated expression, and then said to his men: "Bring the murderer's body back. This case has been completely solved."
After getting the confirmation from the team leader, the discussions around became even louder, and the team leader and his men sent people to search Xiaopang's house thoroughly. They would probably soon find the shroud hidden in the house that Xiaopang's father used to scare people. However, the two people who had seen the shroud, Dong Ge and the captain, were already dead. Even if they found it, no one would be able to testify against it.
From beginning to end, I didn't dare to look at Xiaopang and Xiaopang's mother who were not far away. I didn't dare to face them at all at this time, and I was even a little afraid of them. After all, everything I did made this family, which could have turned the tide, fall into bad news again.
Perhaps seeing through my thoughts, Lin Yingxue pulled me out of Xiaopang's yard, away from the gazes of Xiaopang's family and the discussions of people around us. I immediately felt much better. But we hadn't walked far when I saw my father standing there looking at me. Although he didn't say anything, from the approval in his eyes, I guess he was also very satisfied with my investigation this time.
I tried to forget all the negative emotions, walked up to him and said with a smile, "Dad, how did I do this time?"
Because I told Lin Yingxue before that my dad already knew our identities, and my mom was always there, Lin Yingxue couldn't greet my dad properly. My dad was alone at this time, so Lin Yingxue immediately stood at attention and saluted respectfully, "Hello, senior!"
My dad smiled slightly and returned the greeting to Lin Yingxue, then turned to look at me and said, "Overall, you did a pretty good job. You were able to understand my hints to you, which surprised me the most. However, although the case has been solved and you have found the real murderer, there are still many suspicious points that you have not discovered!"
