Three people and one ghost solved 43 mysterious cases.

One day in 1920, 44-year-old Luo Miwen took a train from City A to City D.

This person has a middle income, has just been paid, and carries 270 yuan with him.

He often takes the train from City A to City D, doing some small business here and there.

At that time, the train carriages were all small boxes, and there were more than a dozen boxes in one train.

There are two benches in each box, sitting opposite each other.

When the terminal arrived, the flight attendant in the car reminded the passengers to get off. The flight attendant walked to Luo Miwen's carriage and found some blood on the ground inside the carriage.

Looking down, Luo Miwen's body was hidden under the bench in the carriage.

The flight attendant hurriedly called the police. When the police arrived, Luo Ye died, having been shot five times in the head.

I asked the flight attendant and several passengers, and they all said they heard no gunshots.

This was because the carriage Luo Miwen was sitting in was close to the locomotive, and trains in those days were very noisy.

So even if the murderer fired five shots, the sound was masked by the sound of the train.

The five shots in Luo Miwen's head were fired from bullets of two calibers.

The police judged at the time that since there were two caliber bullets, they might have come from two pistols, and the murderer of Lu Miwen might have been two people.

Luo Miwen's money was looted, and there was no doubt that he was murdered.

.

Soon, the police found a suspect named Ma Chengwu.

This Ma Chengwu, 44 years old, knew Luo Miwenhui, but was not very familiar with him.

Ma Chengwu used to have a good life, but over the years he has been addicted to horse racing and lost everything.

And according to the statements of two witnesses on the train.

Both witnesses said they saw Ma Chengwu and Luo Miwen in the same carriage.

Ma Chengwu is very suspicious. Maybe when they were in the car together, he knew that Luo Mimen happened to have 270 yuan on him, so he directly sought wealth and death.

The police took Ma Chengwu back to the police station and asked, "Tell me, who is your other accomplice?"

Ma Chengwu shouted that he was wronged.

He said, yes, I have met Lu Miwen, and I also took the train from City A. I just saw him when I got in the car and said hello to him.

After that I went to buy a newspaper.

Then, I got on the train. I didn't sit in the same compartment as Luo Miwen. I said hello and went to another empty compartment to read the newspaper.

My destination is city b.

But I was so absorbed in reading the newspaper that I missed the stop in City B. Then the train arrived in City C and I got off immediately.

After getting off the train, I made a replacement ticket with the conductor on the train platform.

Then I plan to walk from City C back to City B.

I walked and walked, but after walking for a while, I felt out of breath, so I sat on the grass and rested for more than an hour.

Then I realized I couldn't walk to City B.

So I turned back to the platform in City C, where I met two acquaintances and chatted with them for a while.

.

Based on Ma Chengwu's "alibi", the police went to verify.

It’s true, he did get off the train in City C, and after “missing” for two hours, he returned to the platform in City C, met two acquaintances, and chatted for a few minutes.

Acquaintances said that Ma Chengwu's expression looked normal at that time.

But this is not a complete alibi.

Because he most likely shot and killed Luo Miwen during the journey between city b and city c, and then got off the car.

Moreover, the police thought that he wasted two hours in City C and rested on the grass. This statement was ridiculous.

.

Two witnesses on the train were notified to come and identify the person.

The two witnesses got on the bus from City B. When they got on the bus, they took a glance and saw Ma Chengwu in the same compartment as Luo Miwen.

But this evidence is not sufficient.

In this way, three months later, Ma Chengwu was also detained for three months.

One day, the police found a pile of cash and property next to a mine in Taoyuan City, near City C.

These items were confirmed to belong to the deceased Lumiwen.

This mine is only 2.4 kilometers away from the station in City C.

And this easily explained what Ma Chengwu did in the two hours after getting off the bus in City C. He went to hide money.

It was said before that two bullets of different calibers were found in the head of the deceased. The police judged that Ma Chengwu might have had two pistols on him, and he was the one responsible.

So Ma Chengwu was taken to court.

The court's judgment is mainly based on the testimony of witnesses.

The court sentenced Ma Chengwu to be hanged, and in 1920, he ended his life with a hemp rope.

·

At this moment, in the office of the crime team.

Yao Ruolan finished describing the case from 80 years ago.

She said that this case seemed to be committed by Ma Chengwu.

However, the actual evidence is not sufficient.

If it was Ma Chengwu who committed the murder, why did he bring two pistols to murder?

Regarding this, I made a conjecture when I read this report before.

In fact, Ma Chengwu carried a pistol, but used two different types of bullets.

Yao Ruolan took a piece of paper and demonstrated her reasoning.

If there are two caliber bullets.

You can insert a small-caliber bullet into the pistol by simply rolling an item such as a newspaper around the surface of the small-caliber bullet.

Then you can shoot two kinds of bullets with one pistol.

After hearing this, Thirteenth Sister was confused, "Boss, the evidence in the case you mentioned does not seem to be very sufficient. Why did the court issue a sentence of hanging back then?"

"On this point, I also read some newspapers from 1920. Ultimately, it was Ma Chengwu who had the problem."

Yao Ruolan said that before this murder case of Lu Miwen, Macheng Wu was actually suspected of three other shooting cases.

However, due to lack of evidence, the police have been unable to charge Ma Chengwu.

Maybe this fourth case happened again, and the police and the judge subjectively decided that they must find a way to convict Ma Chengwu.

Before Ma Chengwu was hanged, he was interviewed by a reporter and said firmly that I did not kill anyone and that I was unjustly accused.

·

At this moment, the office of the crime team.

Yao Ruolan said:

Although the train murder case of Macheng Wu is not related to the chicken coop dismemberment case of Chen Shumin.

Both of these men appear to be guilty, but I am curious whether one of these two men in 1920 was really innocent?

She assigned a task to Thirteenth Sister and Fatty, "Since you will return to Taoyuan City in 1920 this time, you just have to go find them and see if you can solve the mystery of the two cases."
