As long as the murderer is still a person, it is impossible for him to do more than he can do.

As previously speculated, he stepped on the victim's footprints and killed him from behind with a blunt object, and then went backwards......

- This is not Assassin's Creed.

Besides, An Yizhi had also seen the victim's footprints, and there were no traces of repeated trampling.

The victim walked here on his own, and then was killed by the killer by means unknown for the time being, until the body was found in the morning.

Then again, why did the mayor of the town come here in the middle of the night without sleeping and wearing a bathrobe?

"Look there, there's a piece of paper under Mr. Mayor's chest."

Hearing Yumeko Mizushima's prompt, Ann lifted the body lightly with a finger, and there was indeed a piece of paper there.

The paper was A4 size, and there were some things written on it in printed fonts, but most of it was contaminated with dried bloodstains, and it was completely impossible to see what was written.

He turned the paper upside down and pointed it at the sun.

In this way, the handwriting that was originally unreadable can be read to some extent, and the reason is similar to the effect of a doctor in a hospital looking at an X-ray.

"What's written on it?"

After a few glances, An Yi pointed and said:

"It's basically about the mayor, like how he bribed the city officials to build a highway for the town, or how he cashed his own pockets when the mines were still producing gems."

"So, Mayor Mare's got up in the middle of the night and walked here to find this piece of paper?"

"Well, I think it's right, it's likely that the murderer used this handle to ask the mayor here, probably to make some kind of deal or something, but the mayor didn't expect him to come here quietly and wait for him to be killed."

The corpse was opened by Ann's fingers, and in addition to the piece of paper, an unusually protruding snowdrift could be seen underneath him, which was obviously different from the snow around him.

Maybe it's a clue.

While pondering how to proceed, Ann heard a noise from a propeller.

A helicopter with the word "police" on it was seen flying quickly and landing in the small square opposite the hotel, and a group of police jumped out of the helicopter carrying boxes that might contain identification tools.

Although the police in this world are very unreliable, the speed of the police still has to be praised, because the heavy snow covers the mountain roads and is not easy to walk, and it is really awesome to use a helicopter directly.

But......

An Yizhi saw that the young policeman with blonde hair who was about the same as Erha when he got off the helicopter first, and he wanted to complain.

- Is this the only policeman in this country?

–‐‐——–‐‐——

The policeman who went to the scene this time was still Jimmy, and the other party was also stunned when he saw An Yizhi.

Jimmy said that he had received the above commendation for several previous cases (all related to Ann Yizhi), and this time he was temporarily transferred to a nearby city to give a speech, and when he heard the news of the murder, he immediately came with the team.

Regardless of the reason, at least one acquaintance is in the police, and it will be much easier for An Yizhi to want to investigate.

At present, the professional forensic personnel of the police are busy working on the body, and the people who stayed in the hotel are also being questioned by the police.

In terms of the speed of investigation, it is much faster than An Yizhi himself, and it is also much more professional.

Now Yasuchito, Yumeko Mizushima, and Jimmy are in the lobby of the hotel, sitting on the sofa and waiting for the result.

As I said before, although it is mainly up to detectives to solve crimes, the police in this world are really admirable in terms of investigation, and after Jimmy explained a little why he came here, the police sent a preliminary investigation result.

"The time of the victim's death is presumed to be between 1 and 3 a.m., and the cause of death was a strong blunt blow to the back of the head, judging by the type of wound that was a spherical object with a diameter of about 15 to 20 centimeters. Judging from your description and the photographs of the scene provided by Mr. Ahn, no footprints of the killer were found. ”

Jimmy said, and couldn't help but have a headache:

"How did the murderer kill without footprints?"

"I have a guess about this......"

Before An Yizhi finished speaking, he saw the proprietress coming out of the temporarily requisitioned room next door accompanied by the police, and An Yizhi threw away the topic he originally planned to talk about and stepped forward to ask:

"Boss, I want to ask if the surveillance camera was working last night?"

The proprietress seemed to be a little dazed, it was already scary to see the corpse with her own eyes, and it was understandable that she was interrogated by the police.

She reacted half a beat slower, and then said:

"Yes, the video of our hotel is automatically cleaned up once every half a month, and last night's video should still be kept."

"By the way, I was about to say that, too."

Jimmy Says:

"If you have a camera, you should be able to see the prisoner or the victim, and it would be even better if you could capture the scene of the crime."

In modern society, surveillance cameras can often play a key role in solving crimes, and the popularity of this thing greatly affects the difficulty of solving cases and the determination of accident disputes.

But the problem is that the murderer must also know about the camera, and since he dares to kill people, he must be some vigilant about this, and it is really difficult to say how much information he can see.

An Yizhi wanted to look at the camera, mainly to determine who the prisoner was, and even if he was on guard, he could find some clues.

After all, this commission is only a part of the temporary dungeons on normal difficulty, and the difficulty is not excessive, and it can even be said that the difficulty of puzzle reasoning is much lower than many temporary dungeons encountered before.

Then the proprietress opened the computer folder where the video was stored and asked An Yizhi to watch it with the police.

Since the time of death is presumed to be between 1 and 3 a.m., the video recording during this time is the most important.

During the business period, the lights in the corridor of the hotel are on 24 hours a day, but since there is no one else living in them except An Yizhi, the lights in the corridor on the first floor have been turned off at night, which makes the video somewhat unclear, but if a large living person appears in the corridor, it can be seen.

As the footage fast-forwards, the time shown in the lower left corner quickly comes to the inferred point in time.

The figure of the victim, the mayor, also appeared in the picture, and the time was shown as 1:52 in the morning.

He was then seen walking through the camera at the main entrance, illuminated by the street lamp, outside the hotel, and heading to the left.

"The exact time of the victim's murder is estimated to be at this time, is there a camera that can see the scene of the crime?"

The proprietress shook her head:

"There's only indoor monitoring over there, I'm afraid I can't see the outside ......"

"It's okay, let's try it, if you can see something, it can also be the key to solving the case."

Since the police insisted, the proprietress had no reason to refuse, and besides, she wanted to catch the murderer more than others, after all, this was a homicide that happened in her hotel, and if it was not settled, once it was spread, there would be no way to do business in the future.

Then she called up a wall away from the scene of the crime, and the surveillance in the room, from the edge of the screen, she could see a part of the body belonging to the mayor, the time was 1:57 in the morning, and the mayor was still alive at this time.

As the time in the video passed minute by minute, at about two o'clock in the morning, a black shadow suddenly crossed the window in the picture, and the mayor's body fell to the ground.

And the most important thing is that the black shadow is not photographed at all, and there is no trace of the murderer.

The cameras in the hotel are all of the old-fashioned type, the camera's field of view is not only narrow, but also cannot be rotated, the only advantage is that the clarity is OK, but no matter how high the definition is, it is useless, and it does not capture any useful clues.

Jimmy looked a little disappointed, but Ann pointed and said:

"Boss, where do you usually put the keys to the second and third floors?"

The proprietress didn't expect An Yizhi to ask this, but she still replied:

"It's usually hung on the wall of the kitchen, but it's rarely used, and it's only in the off-season that we lock the doors to the second and third floors."

"Who else knows the location of the key but you?"

"I probably know it, it's not a key that's too important."

"Does that mean anyone has the opportunity to get the key to open the doors on the second and third floors......

Jimmy was confused by Ann's question:

"Mr. An, did you find anything?"

"I've figured out how the murderer killed, but the problem is how to narrow down the scope of the murderer."

It's not a blow, because the methods used in this case are not difficult, the problem is to find out who the murderer is, I'm afraid more clues are needed.

–‐‐——–‐‐——

Because the surveillance video may have a clear connection with the case, it was put into a USB flash drive by the police and taken away as evidence, and An Yizhi also instructed the police who came with Jimmy to watch the video again, especially to see if anyone passed through the entrances to the second and third floors.

But having said that, I'm afraid there won't be any evidence left on the video against the murderer.

After all, there are only six surveillance cameras on the first floor, including the one facing the door, and only one camera that can see the stairs leading to the second and third floors.

The structure of the hotel is roughly such that the elevator is in the center, that is, behind the vestibule, and there are safety exits and stairs at the ends of the corridors on the left and right, but only the staircase on the right can be seen by the camera, and the left side is completely invisible.

If An Yizhi guessed correctly, the murderer must have carried out a murder plan upstairs, and he must have deliberately avoided the camera to go upstairs, so it is really hard to say how many clues can be left on the surveillance video, and such a troublesome and patient matter was thrown to the police by him.

But what is certain at the moment is that the guy who can do this must have some familiarity with the hotel, otherwise it is impossible to avoid the camera so perfectly.

In other words, the mayor's killer was among the several people who spent the night at the hotel.

Needless to say, the proprietress and her children have grown up in a hotel and must be very familiar.

Erin and Svedi, the truck driver, are also guests at the hotel, and it is not difficult to know the location of the camera and make a murder plan if you have the heart.

As for the motive for the killing, which requires the end of the police interrogation and more visits and investigations, what may only be known, An Yizhi now has to go upstairs to confirm whether his conjecture is correct.
