One thing that can be confirmed is that at the scene of the murder, the murderer once left a huge symbol, and the symbol on the ground should have been large at that time, and the body of the deceased was in the center of this symbol at that time.

It's just a pity that after a few days of heavy rain, all the things that were originally left on the ground were washed away by the heavy rain, and there were only a few vague traces left on the ground.

It is obviously not easy to restore the previous figure according to the traces on the ground.

Now the only direction of investigation, that is, the body of the deceased, may be able to find some effective clues.

It's just that the body was sent to the provincial capital before, and although an autopsy was done, the autopsy report did not come out, and there are still very few things that can be investigated at the moment.

The group could only go to the police station to see the corpse first, and as for Liu Jian, he took the small piece of metal that Qin Lu sent you to the silver jewelry store to check the silver content of this thing.

In fact, this trace examination department can also do this, but it still takes a bit of time for the relevant data to come out completely.

And those more famous old shops, there are generally some old shopkeepers who sit in the shop, these people's eyes are very thief, and you can see the ingredients of this thing at a glance.

Once it is determined that this thing is related to the case, when the time comes, it will be sent to the trace examination department, and the provincial one will send it over for nothing.

And Liu Jian's half really lived up to expectations, in less than half an hour, the things in his hand had been confirmed, the silver content was very high, it belonged to pure silver products, but the outer oxide layer was carbonized because of the high temperature.

As for the red one above, the old shopkeeper means that it is caused by vulcanized products.

This point is almost the same as Qin Lu's idea, and the thing is directly sent to the trace examination department, and a detailed test is arranged immediately.

On the other side, Qin Lu was not idle, although the corpse had already been cut somewhat, but fortunately, it was a relatively complete corpse, as long as all the things presented on the corpse were recorded.

The corpse had extensive burns, and the clothes on its body were completely carbonized, and there were basically no relics.

Ding Fan's desire to find something to prove his identity from this corpse is undoubtedly looking for a needle in a haystack.

After a day of tossing, Ding Fan hardly found any useful clues in his hands, and it was almost a headless case.

Perhaps at this stage, in the whole case, what is somewhat useful is a photo taken by the trace examination department at the scene before.

The traces of the graphics on the ground were obviously much clearer than those seen today, but they were still incomplete, and perhaps only by knowing what was drawn on the ground could he associate more things.

......

Early the next morning, the office prepared by the police station had been cleaned up, and it was only three or four people who used it anyway, and it didn't take much of a room.

A table with four chairs, plus a relatively large computer desk for Liu Jian's use, and the rest are some archival materials.

Ding Fan is very satisfied with this office, and he can't use superfluous things anyway.

"Boss, this is what you want!" Liu Jian was busy for most of the night, sorting out all the relevant cremation cases in Pengcheng in recent years, and finally putting things together.

"Within five years, there were a total of seven similar cases in Pengcheng, two of which were accidents, and five of the other five cases were intentional homicides!" Liu Jian said, connecting the projector to the computer, and then projecting the things on the computer, and the photos appeared on the wall.

Zhu Zhenyu was responsible for coming over to help, and when he saw Ding Fan's investigation methods, he was still sitting silently on the side to record, but he still had a certain sense of identity with their investigation methods.

Especially among these cases, there is another case that he has participated in the investigation before, but at that time he was still a newcomer, and he didn't do much in this case, most of the time, he just ran errands.

"Sun Lizhen's case, I know one thing, she has a conflict with her husband, and she killed someone in public, it should have nothing to do with this case!" Zhu Zhenyu raised his hand cautiously and said cautiously: "I participated in the investigation of this case before, Sun Lizhen was abused by her husband for a long time, and she was a little mentally disturbed, and she is still in a mental hospital, this time it should have nothing to do with her!"

In fact, Ding Fan didn't think the two cases had anything to do with each other.

After all, Sun Lizhen, who he talked about, had a very simple and clear motive for killing.

She was abused by her husband for a long time, which led to serious mental problems, and she almost did not hesitate to kill, let alone make too much preparation.

At that time, if it weren't for the hot pot restaurant, the charcoal stove encountered high alcohol, and his husband might not have died.

It is not an exaggeration to say that this case is an accident, according to this, Liu Jian should also be able to think that he finally pointed out this case, eighty percent of it is that there may be something in this case, or it may be related to this case.

Sure enough, Liu Jian glanced at Zhu Zhenyu, enlarged the photo on the computer, and then circled the photo with the mouse and said: "This is the key, there is a certain amount of chance in this case, and I didn't plan to include this case at that time, but I accidentally saw this flag, and the logo on it looks a bit like a trademark, but I compared the photos taken by the trace examination department at the scene before, and the two pictures are 30% similar." ”

"I didn't put things in because of this case, I just wanted to know what was drawn on this little flag, and maybe it had something to do with the pictures that appeared in this case. ”

Not to mention, if Liu Jian hadn't marked this location, Ding Fan would almost not have noticed this little thing.

Looking at the mountain is a bit like an alternative flag, as for what exactly is painted on it, it is not very clear because of the pixels.

"Is this restaurant still open?" Ding Fan flipped out the photo in his hand, carefully identified it, it looked a little familiar, but it was not very clear, so he could only ask Zhu Zhenyu: "Haven't you been to the scene, have you ever seen this thing?"

Zhu Zhenyu frowned, carefully recalled what he saw before, scratched his head and said: "It seems to be a very common thing, not very strange, a small blue flag, what is painted on it, I really can't look like it, but this store is still open, it was opened by an uncle's family!"

Sect?

When Ding Fan heard this, he immediately remembered, stretched out his hand and drew twice on the white paper, handed it to him and asked, "Is this the thing?"

Zhu Zhenyu glanced at it and nodded hurriedly, like a chicken pecking rice.

Ding Fan shook his head and said: "No need to check, it should be the flag of the sect, this kind of thing is not uncommon, there are ordinary sect restaurants, it belongs to the sectarian ......"

Halfway through his words, Ding Fan suddenly stopped, as if the whole person was instantly stuck.

Zhu Zhenyu didn't know Ding Fan's habits, and he was stunned and wanted to reach out and touch it, but fortunately, Liu Jian reacted quickly, hurriedly rushed forward, grabbed his hand, and then shook his head at him.

He knew that once Ding Fan looked straight ahead with his eyes and didn't say a word, Bacheng thought of something, and he couldn't disturb him at this time.

"Fatty, find out all the sectarian flags and icons for me!" Fortunately, this time Ding Fan only thought for two minutes, and quickly reflected, glanced at Liu Jian and said: "In addition, Xiao Zhu, you can help me find a map to divide the location of the sectarian ethnic accommodation in the entire Pengcheng and mark it according to the color." ”

"Boss, what do you mean...... It is very likely that the murderer has a sectarian background?" Liu Jian immediately frowned a little when he heard the word sect, after all, cases with sectarian background are generally very troublesome, not only are it difficult to investigate, but even the final arrest is very difficult.

But Ding Fan shook his head and said uncertainly: "I don't guarantee it, but I always have to check!"

"By the way, Xiao Zhu, didn't your captain say before that there was a fortune teller who saw something?"

"Find this guy for me, I need his help!"

Speaking of sectarian affairs, Pengcheng is really a bit complicated, after all, Pengcheng belongs to the coastal city, in ancient times, there were even many merchants from overseas here to trade with each other, at that time there was a certain amount of confusion in the population here, and even a lot of mixed races, foreign merchants even settled here, and at the same time, there were many foreign missionaries who followed these merchants.

It's like the Nestorian Christians who came from Europe during the Tang Dynasty, and the Persians at that time, and so on.

Wherever the missionaries walked, there were some believers left behind, and whether they remained here in the future or not, these believers were recognized.

Therefore, the sectarian beliefs of the Pengcheng generation were relatively chaotic, and some people even said that they were more exaggerated, saying that the sectarian beliefs of a family of three could be completely different.

It is conceivable how developed the sectarian culture of Pengcheng is.

If it weren't for the Xingyue Banner that Liu Jian found at that time, Ding Fan really didn't think of this.

It's not that this case really has anything to do with the sect, but the graphics drawn around the deceased at that time look not small, and it shouldn't be a complicated picture, so it is very likely that the sect symbols will be copied.

As long as he determined which sect this symbol came from, Ding Fan would have a way to find someone to identify the meaning of the rune and confirm the motive for the killing.

As for the identity of the deceased, it depends on whether Qin Lu can provide some useful clues.

Liu Jian, who didn't know much about the sect itself, investigated on the computer for a long time, and finally checked it out in a daze, rubbing his eyes and saying helplessly: "Boss, I think your way of finding a needle in a haystack is a bit tricky, do you know how many sects I found just now?"

"There are five sects that are more officially recognized, but there are still many factions among these sects, and I am dazzled by them!"

Ding Fan held a pen in his hand, drew the mutilated pattern taken by the deceased on the spot on the paper, handed it to Liu Jian and said: "I've also heard of some, so I don't plan to ask you to find out all of them, and when Xiao Zhu comes back later, he has determined how many sect settlements there are in Pengcheng, you are looking in this direction, and you can find out what is in line with this general pattern!"

The matter of sectarian beliefs is not the key to the case itself, but only the direction of investigation now.

It's not a big deal on the whole, and it's not certain that this case is necessarily related to sectarian rituals.

At least Ding Fan hadn't heard of a sect where people came to make sacrifices, and it was enough to listen to it.
