Detective Training Manual

"This..." Zhou Yan scratched his head.

"So, does this hotel have a camera?" Zhou Yan asked as usual.

This is not Zhou Yan being lazy, after all, the camera is the most powerful evidence of all cases.

However, as he had expected it a long time ago...

"In our small town, it's not bad that the fire protection is up to the standard. How can there be a camera?" Xiao Chen said with embarrassment.

"What should I do if the passenger loses his stuff?"

"Be responsible for yourself." Xiao Chen said.

"Okay~" Zhou Yan quickly accepted this setting. Cameras in this world have always been furnishings. Anyway, as long as there is a case, the camera will be very punctual, because of various reasons. , Or not at all.

It is estimated that this is also one of the reasons why the detective system in this world is so developed.

Then, return to the case itself.

"So, at this moment, if you throw away the dead, there are only 5 guests in this hotel, right."

"Yes." Xiao Chen returned.

"Furthermore, two of the men went out for a drink last night and did not come back. There is also a couple who only checked in this morning... so... they were in the hotel last night. , There is only Zhang San alone."

"If you don't count the deceased, it is true." Xiao Chen said affirmatively: "Furthermore, we contacted the Archives Bureau of 19 Districts by phone and found that Zhang San's past resume was not very good. There were precedents of harassing passengers. , I was divorced twice and fought with other drivers in a small restaurant. Oh, and his car should have been repaired a long time ago, but he still drove passengers. In short... this man is not too clean. "

"Uh~ Third Brother is really a man of temperament~" Zhou Yanthi murmured embarrassedly in his heart.

"So, our vision is like this.

Last night, there was only Zhang San and the dead in this hotel. The deceased was a woman with a very beautiful appearance. Zhang San was upset and wanted to do something nasty to the deceased, but was rejected by the deceased.

Therefore, Zhang San deliberately retaliated this morning, using the ten seconds of the elevator stopping on the fourth floor, rushing into the elevator quickly, using a fire axe to directly cut the neck of the deceased, and then quickly withdrawing from the elevator.

After that, the elevator descended to the first floor. After seeing the body, the two passengers called the police. When we arrived here, it was already 7:15.

During this time, Zhang San buried the murder weapon in the flower bed in the backyard. "

Xiao Chen briefly talked about his conjecture.

Of course, he is just a policeman. This kind of conjecture is very one-sided, and there are many small details that cannot be explained.

And one of the most worthy of Zhou Yan's attention is...

"Um, Brother Xiao Chen, how did you determine the identity of the deceased?" He asked involuntarily.

The head of the deceased is gone. According to the plot in the usual novels, if there is no head, or a corpse with a severely damaged face, then ten of them have been transferred.

"Oh, by the way, I haven't told you about the deceased yet." Xiao Chen said with afterthought: "The deceased's name is Li Xiaoli, 29 years old this year, unemployed, and he stayed in the hotel yesterday morning.

After our police arrived at the scene, they first determined the identity of the deceased based on the clothes of the body. "

With that, Xiao Chen took out a stack of photos from his pocket and handed them to Zhou Yan.

Zhou Yan took the photo and found that it was a close-up of the body leaning in the elevator.

Xiao Chen continued: "The corpse is wearing a blue windbreaker. The staff at the hotel bar can be sure that this is what the guest [Xiaoli] on the sixth floor wears.

Moreover, the height and body shape are also roughly matched.

Most importantly, we found her shoulder bag beside the deceased, which contained her ID card, which was Xiaoli's. "

Zhou Yan listened and looked at the photos in his hands. He couldn't help but hesitate to say: "Uh...Although all signs indicate that this is Xiaoli's body,... she still doesn't have a head. Ah, so if the murderer gets a corpse to impersonate Xiaoli, it's okay."

"This is possible in theory, but if you start from the actual situation, it is very difficult to do." Xiao Chen said: "Because at that time, the couple on the first floor were staring at the elevator floor. They could all. To be sure, the elevator only stayed on the 4th floor for less than 20 seconds.

During this time, if the murderer wants to take off Xiaoli's clothing, put it on another person, and then behead her head, there will be no time at all. "

"Could it be that the clothes exactly like Xiaoli were prepared in advance?"

"Emmm..." Xiao Chen hesitated: "I haven't thought about this..."

at this time......

"Ling~Ling~Ling~"

Xiao Chen's phone rang.

Xiao Chen answered the phone, answered briefly, then hung up.

"Well, after the autopsy, the identity of the deceased has been determined, and it is Xiaoli!" Xiao Chen said.

"Um...well." Zhou Yan raised his eyebrows.

Originally, I thought there would be some tactics like changing the head and killing people, but in the end there was no such thing as the corpse was Xiaoli's.

"Then, the next question." Zhou Yan continued to ask: "You said, from the time you call the police to when you arrive here and block the scene, there is a full 15-minute blank period. During this time, the murderer has enough time to The murder weapon was buried in the flower bed... But the murderer walked out of the hotel so generously with a fire axe and blood. Isn’t it a bit too eye-catching? The staff at the bar Didn't you see it?"

"We have also considered this, but unfortunately, this hotel has more than one exit at the main entrance.

At the rear of the first floor, there is a safety exit. "

With that, Xiao Chen pointed to the other side of the corridor where the elevator was.

Zhou Yan walked in that direction and found a flight of stairs, and where the stairs were directly opposite, there was really a door with a safety exit sign painted on it.

Zhou Yan walked back to Xiao Chen again...

"So, the murderer can be on the 4th floor, behead the deceased, run down the walking stairs, and then directly open the door of the'safety exit' to get out."

Xiao Chen nodded: "Yes, and after the safety exit, it is in the backyard of the hotel. The flower beds are also very close. Ten minutes is more than enough."

"Then... where's the head, haven't been found?"

"Yes, I didn't find it." Xiao Chen said, "I don't know where the murderer was hiding. The police station asked Zhang San, but he completely denied that he had any contact with the deceased. He knows who the deceased is, and he is naturally tight-lipped about his head."

"Hey hey~" Zhou Yan reminded me depressed: "People just have suspicions. What is "keep your mouth shut", as if Zhang San must be a murderer."

"This...well, I used the wrong words, but this suspect seems to have no other choice except Zhang San."

"Why is there no candidate?" Zhou Yan said: "Although the elevator has only stopped on the fourth floor, the fourth floor is not a closed space. Maybe someone went to the fourth floor and killed the dead when the door opened. At that time, Zhang San might still be sleeping in the room."

"Um..." After listening to Zhou Yan's words, Xiao Chen seemed to be a little embarrassed: "Um... I'm really sorry, I didn't make it clear. At the time of the case, this hotel except Apart from Zhang Sanhe and the dead, there were only four people left.

These are the two drunks on the sixth floor.

There is also a couple on the first floor.

And these four people all have an alibi. "

Zhou Yan thought about it again. Indeed, because the two drunks saw Xiaoli walk into the elevator.

The couple saw Xiaoli's body after the elevator reached the first floor.

There is no suspicion of these four people.

Therefore, the only suspect left is Zhang San on the 4th floor.

Zhou Yan hesitated for a while...

"So, will there be other people in the audience, for example, will there be someone or someone who sneaks in while the staff at the bar is asleep, and then hides in a corner on the fourth floor? , Waiting for the opportunity to kill Xiaoli?"

Xiao Chen shook his head: "Impossible, because after we arrived here, we immediately sealed off the entire hotel and checked all the floors. We were sure that there were only these few people in this hotel.

The service staff at the bar also confirmed that no strangers have ever entered or left the hotel after 7 o'clock.

At that time, we also thought about whether someone ran over the wall from the backyard.

But when we came to the backyard, we rejected this idea.

Because there is no exit in the backyard, there is only a three-meter-high fence. Because there is no monitor, barbed wire is also placed on the fence to prevent thieves. Most people can't climb up, let alone climb over.

To sum it up, it is impossible for anyone else to appear in this hotel. "

"Emmm..." Zhou Yan frowned.

There are only five people staying in the hotel.

The two on the sixth floor saw the deceased enter the elevator.

The two people on the first floor saw the dead man's body.

During this period, the elevator only stopped on the 4th floor.

Zhang San lives on the fourth floor...

Hiss... At this look, it seems that only Brother Zhang has the possibility of killing people!

Zhou Yan frowned depressed.

Recalling what Zhang Sange looked like in the police station, Zhou Yan seemed to have seen himself a few months ago.

Wasn't it the same for me at the time? Under the seemingly simple case, I was wronged and imprisoned.

It's just that, now his identity has become a detective, and Zhang Sange has become a suspect.

Thinking about it this way, Zhou Yan seemed to be angry all of a sudden.

This case, he must not be so hastily finished.

"Well, although for the time being, it seems that Zhang San is the most suspicious, but our case still has to follow the process a little bit, and there can be no omissions." Zhou Yan said: "So now, let's look at the scene of the crime. "

"Okay." Of course, Xiao Chen nodded. He is a policeman, and it's a matter of cooperating with the detective's investigation.

So, as soon as he raised his hand, he opened the elevator door again.

The smell of blood diffused from the elevator again.

Zhou Yan put on the gloves and mask that Xiao Chen handed over, and walked into the elevator.

He stepped on the dry blood, and he could feel the sticky touch through the thick soles.

But there is no other way. The scene of the crime is too small, so if you want to check it carefully, you can only step on the blood.

Fortunately, people in the forensics department have already taken enough photos of the scene, as well as video shooting, which can be used for comparison afterwards.

Zhou Yan came to the front of the elevator door, where the blood stains were the most, so much that it seemed that he had already distinguished the spray direction without bleeding.

Zhou Yan stretched out his hand and pressed the muddy blood. In some places, it was hard and thick, sticking to the wall.

In fact, under the muddy blood, there is still a trace of an axe on the wall. But because the blood stain was too thick, it was concealed. In order not to damage the scene, no one dared to touch the blood stain until now. Therefore, no one found the trace of the axe on the wall.

After this, Zhou Yan raised his head again and looked at the ceiling of the elevator.

The model of this elevator is obviously an extremely old product, and it doesn't even have a camera.

And there are a lot of blood on the ceiling ~www.readwn.com~.

This is also understandable, because if a person's arteries rupture, the hydraulic pressure can cause blood in the body to squirt far away.

And when the head was cut off, the blood spurted, like a water pipe burst.

Thinking of this, Zhou Yan also frowned suddenly.

It is probably because of the ravages of caffeine all night, his brain slowed down.

He should have thought of such obvious words a long time ago.

"That...Brother Xiao Chen." He said, "You said Zhang San is a murderer, but...is there any blood on his body?"

"Uh...that's not the case."

"But... there is almost a pool of blood in this elevator." Zhou Yan pointed to the surrounding area: "Don't you think that if a person cuts off the head of a dead person here, but there is no blood on his body, this Isn't it reasonable?"
