Ann's explanation was somewhat confusing, and Jimmy didn't understand it at all.

"Okay, then I'll go through the case from the beginning."

He reflexively retracted and walked to the other side of the room, mainly standing in front of the window to blow the wind.

"First of all, the murderer made holes in the windows in advance to fix the iron frame and pulleys, and prepared bowling balls tied with thin wires as murder weapons. Although it is possible to use ordinary hemp rope, it is relatively easy to expose if the hemp rope is too thick, and the thin line may be a fishing line or a piano line. Subsequently, he may directly or indirectly reveal a piece of information to the victim by hiding his identity, which is the A4 paper under the victim, which is full of evidence of his embezzlement, and uses this as a threat to ask the victim to come to the scene of the crime at a specific time.

Then An pointed to the window and said:

However, the victim did not expect that before he arrived, the murderer had already hung the iron frame with pulleys and a bowling ball above the window in advance, and because it was the dead of night at that time, he couldn't see that there were still things hanging on it if he didn't turn on the lights at all. The victim stupidly came to the place of murder, and then the murderer untied the rope and let the bowling ball fall, killing the victim, and finally pulled the bowling ball up through a pulley and put it in a plastic bag and other things to take away. This way, there will be no footprints around the victim, which is what the body looked like when it was found."

"Mr. Ke'an, you still haven't answered me why the murderer can accurately locate the victim."

"It's very simple, I just said that there is a clearly protruding snow mass under the victim's body, and there should have been a snowman there."

Yumeko Mizushima immediately woke up and said:

"The kind of snowman you have all over town?"

"Well, that's right, it's easy to make a snowman, just fill a container like a plastic storage box with snow and make two square pieces of snow and pile them up, and carve a pattern on your hand. The killer experimented with the location where the bowling ball fell in advance, and built such a snowman at the location as a positioning point. ”

Jimmy wondered:

"Even if there is a snowman there, it shouldn't have anything to do with the victim being smashed, right?"

"Of course it does, the A4 paper full of evidence of his corruption is in the snowman, and I guess the murderer mentioned this when he threatened the victim, such as 'If you don't believe that I have evidence of your corruption, you can go to the snowman outside the hotel, there is a backup there' and something like that."

Seeing that Jimmy was still a little unclear, Ann Yizhi sighed and said:

"Officer Jimmy, what would you do if you were to find an A4 paper buried in a snowdrift about the height of a coffee table?"

"How? Bend down with your hands, of course...... Yes! That's it! ”

An Yizhi nodded and said:

"That's right, the victim did the same, he bent down and lowered his head to dig up the snowman with his hands, so that no matter where he stood next to the snowman, the position of his head would always be fixed, and the position of his head was hit by the bowling ball that the murderer had carefully tested."

"I see, Mr. An, you are really amazing."

An Yizhi hurriedly waved his hand modestly, not because he didn't want to show off, but because this kind of killing technique had already been used by a certain Grim Reaper elementary school student.

Yumeko Mizushima said:

"In other words, why did the murderer kill people with this method? Since he has the handle of the victim in his hand, it should be more convenient to ask the other party to a secluded place to do it directly, and this method does not seem to be done to get away with it. ”

Killings, especially murder, are more about getting rid of the suspect, and the modus operandi is clearly not like that in this case.

But it's not without reason.

"Reason? That's a lot. For example, the murderer is a woman, and her physical strength and strength cannot kill people directly, or is it ...... Remember that legend in town? It is said that the town's patron saint will drop bad guys from the sky. It may also be that the murderer wants to use this to announce that the mayor is a bad guy and that he is doing the right thing for heaven. Whether it's for public opinion or just psychological self-satisfaction, there are many reasons to use this technique. ”

Jimmy looked at the notepad and said:

"That being said, the killer must have been someone who was very familiar with the hotel and had the opportunity to test the location of the bowling ball...... I feel that the suspicion of the proprietress's family seems to have grown. ”

"It's not just the proprietress family, I learned yesterday through casual chatting with other people, including the victim, that the other two often visit the hotel during the off-season of tourism, plus the proprietress mismanages the keys, as long as there is a heart, any of these people have the opportunity to carry out this murderous method."

Speaking of which, although the murder method has been cracked, the number of suspects has not decreased in the slightest.

This is also where An Yizhi feels more painful, whether it is the scene of the murder or the scene where the murderer executes the murder method, there is no clue that can be found along this line to find the murderer's true body.

However, it is not completely without clues, and the clues are in the police record.

The motives for the murder of these five people, except for Erin because of the difference in household registration, all the others revolve around the time period of about twenty years ago.

Originally a miner, Svedi had to change jobs due to the mine that the mayor had closed twenty years ago, and the boss's husband had died twenty years ago, and the anonymous letter also mentioned the truth about twenty years ago.

Twenty years ago was definitely a very important time period, and it is likely to be directly related to the murder cases of today.

However, due to various reasons, An Yizhi has never had the opportunity to ask the proprietress about it, and I feel that now is the best time to ask.

It's just that you can't just listen to the boss's side of the story, so Ann pointed to Jimmy and said:

"Can you help me find out what happened in this town twenty years ago? It is estimated that there are casualties such as homicides. ”

"Twenty years ago?"

Jimmy didn't understand the bend at all, but he promised to contact the city police station to investigate.

–‐‐——–‐‐——

The speed of the police investigation is still trustworthy, the only problem is that the time span of twenty years ago was indeed a bit large, it is said that at that time it was still working with paper documents and archives, and the police colleagues contacted by Jimmy had to work hard to turn through the files page by page if they wanted to check this matter, and it took some time.

Of course, this time can't be wasted, the investigation at the police station continues, and An Yizhi also plans to ask by himself, and when the time comes, compare the situation he asked with the records of the police station, and he should be able to find some clues more or less.

So the three people who came down from the third floor found the sad boss lady again, picked a room where no one disturbed them, and An Yizhi asked directly to the point:

"Boss, I want to ask you, do you know that there was once a snowman at the scene of the crime?"

"No, I don't know."

An Yizhi carefully looked at the expression of the proprietress, especially the eyes, if an untrained person was lying, his eyes would reveal a lot.

Confirming that the proprietress was not lying, An Yizhi pointed and asked:

"Okay, let me change the question, what do you know about what happened twenty years ago?"

Hearing this keyword twenty years ago, the proprietress paused for a moment, and a very sad expression appeared on her face, obviously it was not a good memory.

"Mr. An, why do you ask this?"

So far, An Yizhi has no intention of hiding it, and directly said what was mentioned in the anonymous letter.

"I think what happened in the town twenty years ago may have something to do with this case, so I'd like to hear your explanation, lady."

After hearing this, the proprietress lowered her head and said:

"Twenty years ago is indeed an unbearable memory for me, when I lost my husband and the only source of income for my family, and I had to find a way to raise my two children on my own."

"What the hell happened then?"

"It's a mining disaster."

The proprietress continued:

"At that time, the mayor announced the closure of the mine, but many people did not believe that the mayor said that the mine had dried up, including my husband, so some miners sneaked into the mine at night and planned to dig up some raw gem ore."

"Digging up?"

"Well, it's not something to say openly, my husband said that if the mines in the town were closed, they, the miners, would starve to death, so they had to find a way to get an extra sum of money so that they could go to the city and do some small business or something."

A sad expression appeared on the proprietress face, and big tears also slid down her cheeks:

"But that night came the news of the collapse of the mine, almost the whole town went to the rescue, many people were killed and many people were rescued, but my husband was not so lucky, he was buried underneath. If only he hadn't been greedy to dig up, if only I had been tough enough to stop him, even if we would be poor for a while, at least the people would still be there, but now ......"

As she spoke, the proprietress couldn't control her emotions and cried even more.

The three of them glanced at each other, and An Yizhi handed over the tissue on the table and said:

"Sorry to remind you of bad memories, we don't have anything more to ask."

With that, he glanced at Jimmy and Yumeko Mizushima, and the three of them left the room together.

"Is it possible that the mining accident at that time was not a natural factor but a man-made one, and now the murderer is avenging the mining disaster?"

Mizushima Yumeko whispered to An Yizhi, who did not deny or affirm:

"There must have been a detailed record of what happened at that time, after all, the mining disaster is not a trivial matter, and the experience of the proprietress is indeed worthy of sympathy, but I always feel that something is wrong."

In fact, An Yizhi also made it clear what was wrong, it was just a premonition or feeling.

It's not that the proprietress is lying, An Yizhi's judgment of lying is still very accurate, and it is difficult to hide from him by simply opening her eyes and telling nonsense, but she feels that the proprietress is hiding something and not saying it.

Now you can't continue to ask questions in this situation, especially if you don't know what the other party is hiding.

However, you can't just listen to the boss's wife, in addition to waiting for the news of the investigation from the police, there are other people to ask about what happened twenty years ago, especially Svidie, who was originally a miner, he should know more.

If it really doesn't work, you can only come up with the stupid method of investigation and visit, but this is also a method often used by the police to solve cases.
