Potassium nitrate is generally used in chemical fertilizers and other things, and it's really rare to hear of it being used in other things.

At least in the past few years, most of the potassium nitrate has been used as fertilizers or pesticides.

However, there is not a large amount of farmland around Pengcheng, and even most of it is made by sea, and the development of agriculture is not very large.

People who live in the city, why do they have such a thing as potassium nitrate in their houses?

The scene has been inspected, and nothing like potassium nitrate has been found in the room, which means that it is very likely that the rat did not eat a substance containing potassium nitrate here.

But it doesn't seem right to think about it, potassium nitrate is very harmful, and the rat should have died on the spot after eating it, and it is unlikely that he would have died after eating poison from another room.

Then the question arises, where did the potassium nitrate that should have been on the scene go?

Who transported these things?

The previous problem has not been fully analyzed, and in the blink of an eye, a new problem has appeared again.

The problems that plagued Ding Fan appeared one after another, which gave him a bit of a headache, chewing gum in his mouth, and the masseter muscles that he chewed in the past two days came out.

After thinking about it for a day, he still didn't understand this question, but there was new news on Liu Jian's side.

According to Ding Fan's idea, he went to the video store with Zhu Zhenyu and talked with the boss for an afternoon, and the boss also had a little friendship with Zhuo Fatzi, and he knew a little bit about Ji Ming's affairs, and he didn't hide anything about it.

Even took out the account books they used when they shipped before, and put them directly in front of the two, in fact, there are really not a lot of things he recovered from the outside, that is, some second-hand household appliances, after taking them back, find someone to simply clean them up, and sell them again, they are all recovered by the catty, and they can earn thousands of yuan by changing hands.

And what Ji Ming took from him were small pieces at first, of course, they were also bought with money, and then these things were sold, and recently he has taken a fancy to collectibles and the like, except for foreign coins that are stamps.

The last time I came to him to take away two badges, I heard that it was a foreign nobleman's medal, as for what kind of medal this medal was, in fact, he didn't quite understand, but seeing that Yoshiaki seemed to like this thing, he didn't care about giving it to him.

At that time, Ji Ming was quite happy when he left, and he liked these two little things very much, so he left with his things, but he didn't expect that after this departure, he didn't come back.

The two bronze medals are not valuable in terms of material, but the significance of this thing is far from being as simple as the value of the material.

The problem now is that these two little things are missing.

In addition, the trace examination department sent news that what was detected from the scene yesterday has been basically determined, and the blood clot is completely consistent with the blood type of the corpse.

Then there are some hairs collected at the scene, which cannot be compared with the body of the deceased, and the detailed things need to be seen in more detailed test results.

In addition, the cloth sent by Ding Fan from the evidence room has also been tested, and the detailed ratio has also been investigated, the cloth contains a small amount of cotton and linen, most of which are really good, and from speculation, it should be a white shirt.

This is a bit strange, Ding Fan has been to Ji Ming's rented house before, and he has a general understanding of Ji Ming's dressing habits, he rarely wears white clothes.

Most of the clothes he bought were black or navy blue, and there was only one white one, until he was gone, and the clothes were still hanging at home, and he looked like he rarely wore them.

Hearing this, Qin Lu seemed to think of something, picked up the phone and called Aili.

After asking clearly, he spoke: "I asked, Ellie said that Jiming almost never wears white clothes, saying that white clothes are not easy to clean, he wears some black clothes most of the time, only one white dress is still bought by her, and the clothes he wears are generally medium-sized, but this matter was burned clothes, although the label was burned, but it was obviously too wide, don't ask me why I can see it, as a woman often looks at clothes, I can't see much more clearly." ”

Ding Fan didn't care about these problems, mainly because he has too many questions about the case now, and many things can't be connected at all: "In this way, everyone can talk freely and talk about their thoughts." ”

"I think the identity of the deceased can be confirmed now, and the deceased should be Ji Ming, although we have no way to determine the biological information of the deceased, and there are no fingerprints to confirm, but this blood sample is now available, contact his family, it should be confirmable!" Qin Lu looked at the few pieces of evidence on the table, and finally took the blood clot found at the scene yesterday and said: " In addition, I also found a relatively intact blood lump in the deceased's brain, and I will compare it when I go back, and the results should come out soon. ”

This is probably the most important discovery of the whole case in the past few days, most of the body has been burned, even the blood on the body has been contaminated, and a large amount of chemical agents have been spilled on the body, which has obviously destroyed most of the blood samples.

Being able to get a little blood inside the brain now is definitely good news.

Now it depends on whether the identity of the victim can be checked, as long as there is no problem with the identity information checked, then all the investigation results behind the entire case can be directly applied to it.

After Qin Lu finished speaking, Liu Jian took the opportunity to say: "I think this murder case is a little different from all the cases we have investigated before, the purpose of killing is not very strong, but the sense of ritual is very strong." ”

Liu Jian was halfway through his words, and after listening to it, he looked at Ding Fan's face for a while.

Ding Fan looked at him, nodded and told him to continue.

Liu Jian smiled embarrassedly and said: "I can see that I don't know what is behind it, but I feel that this person seems to be killing people not to kill people, but to engage in some kind of ritual. ”

"I found that there are a lot of points on it, all of which are a bit similar to this case, so I wondered if this murderer could be a movie maniac, he was imitating the plot of the movie. ”

In fact, Liu Jian said that this possibility is really not a casual thing, there have been such real cases abroad.

However, this kind of person often has a certain degree of paranoia, and there is a certain law of crime, as long as he finds the movie he has watched, it is not difficult to find his killing law.

The real difficulty is that his choice of killing people is almost without any rules at all, and anyone can do it.

"If that's the case, things will be a little troublesome!" Ding Fan clasped his hands in front of his chest, frowned and said: "Generally speaking, this kind of murderer, there is no choice when it comes to killing people, it is like completing a ritual, the victim is just his sacrifice, there is a lot of room for choice, and we have no way to confirm who is going to kill next." ”

As soon as he talked about this issue, Ding Fan's whole body became nervous.

From the beginning of the investigation, he already had a bad premonition, and even thought that this matter might be the result, but he himself was not willing to doubt it.

But now all the clues are gradually developing in this direction, and he has to put this suspicious direction on the investigation agenda.

No one knows where he killed, no one knows where he will kill next, and everything seems to be unknown now.

"Ding, do you think there is any possibility of robbing money?" Zhu Zhenyu thought for a while, and still thought that the possibility of robbing money was relatively high: "From the corpse, there were no valuable items on the deceased's body, indicating that before the deceased was killed, his body should have been searched, and generally speaking, only robbers who robbed money would commit this kind of behavior." ”

"It shows that this murderer is not a person with a rich family, he may just be asking for money, and he knocked people unconscious by mistake at that time, he thought that people were killed, and in a panic, he hid the body, and when there was no one, he transported the body away, and finally set the body on fire and hid!"

Zhu Zhenyu's analysis seems to be a bit possible, but there is a big loophole in it, and he may not have found it himself.

But as soon as Liu Jian heard it, he immediately thought of the problem, shook his head and said: "Impossible, if the murderer really only wants to seek money, in fact, he doesn't need to kill people at all, even if he kills by mistake, there is no need for him to transfer the body!"

"And robbery should also be chosen by rich people to rob, Ji Ming like a rich man?"

Ding Fan also felt that this transfer of the corpse was a big suspicion, precisely because this transfer of the corpse became a turning point in the whole case.

"Transferring the corpse is the biggest doubt, in fact, if he wants to destroy the corpse, destroying the corpse in the dilapidated housing area is the best place!" Ding Fan took out the photos taken at the scene before and put them on the table and said: " Most of the houses in the dilapidated housing area are old-fashioned house structures, and many of the surrounding houses are not brick houses, but are made of straw rope mixed with clay, because this kind of house is moisture-proof and warm, but this kind of house is also very easy to ignite, and if you want to destroy the corpse, you can do it in this dilapidated housing area, and there is no need for the murderer to move the corpse to another place!"

When Zhu Zhenyu heard it, it seemed that this was really the case, and his thoughts still had some omissions.

Looking at the other three people in the office, Zhu Zhenyu's shy face turned red, feeling that his brain was simply an empty shell, such an obvious question, why didn't he think of it at all?

"Actually, we ignored a point before, think about it, if I follow our thoughts, the murderer's killings are random, is it possible, his killing of Ji Ming was just an accident!" I took a brief look at it before, and the terrain is like this, to be honest, I can't necessarily get out of it even if I hold the map in my hand, the terrain is complicated, and I think everyone here may not be able to get out of such a complicated route, but the murderer can do it. ”

"And he is very confident that he will do it here, he didn't choose the person he wanted to kill, in fact, he chose only a killing place!"

This should be his first time killing people, so he will choose a location that he is more familiar with to complete this killing plan, and this location, first of all, must be hidden enough, and secondly, he must be very familiar with this place, in case he fails after the shot, he can still escape at the first time. ”

"In this way, the dilapidated housing area has become his best choice!"

Liu Jian pondered and followed all of Ding Fan's analysis, nodded and felt that this analysis was very reasonable, but there was one thing that he still couldn't understand: "It's still the same question, why should the corpse be transferred, isn't it good to burn the corpse on the spot?"

Ding Fan smiled and took a deep breath, pointed to the alley where the murderer was killed, and said: "I said before that once there is a fire here, the fire will not be controlled at all, and the murderer is most familiar with this place, if he loses this place, his next murder will face a certain risk, I think, he doesn't want to lose this favorable terrain!"
